Heat exchanger and heat exchanger flow path closing member and heat exchanger having heat exchanger and heat exchanger flow path closing member

The present invention relates to a medical heat exchanger which is used in a hemodialysis treatment or a blood purification treatment (hereinafter referred to as "hemodialysis treatment" or the like), which is disposable (disposable and disposable) medical treatment. The device is used to exchange (heat) the fluid such as dialysate (hereinafter sometimes referred to as "fluid") from normal temperature to around 37 °C.

More specifically, it relates to a medical heat exchanger having a general shape of a sheet (or a bag shape, a bag shape, a bag body) and a serpentine fluid flow inside. A fluid such as a dialysate flows through the fluid flow path, and the flow path portion of the fluid contacts the heat source (heater) to perform heat exchange (heating), and the medical heat exchanger has an effect of effectively removing the fluid a shape and a structure of a gas in a fluid flow path; a fluid flow path closing means for a heat exchanger, that is, a closing member for promoting gas removal efficiency of the heat exchanger; and the heat exchanger having the heat exchanger and The heat exchanger uses a fluid flow path to close the closure member of the means.

As a conventional medical heat exchanger, the following representative ones are known.

(Prior Art 1)

An invention of a sheet-shaped heat exchanger 111 is disclosed in the patent document 1 (Japanese Laid-Open Patent Publication No. 2002-102349), which is characterized in that the sheet body shown in Fig. 19 is heat-sealed and formed by a spacer. Liquid flow path.

The purpose of the heat exchanger 111 is to improve the fluidity of the fluid from the lower direction to the upper direction (vertical direction) with respect to the direction in which the fluid flows (from the lower fluid inlet 113FI toward the upper fluid outlet 113FO). The plurality of fluid flow paths 113FP inclined by the horizontal line toward the upper direction are combined into a plurality of segments. The heat exchanger 111 is configured to allow the gas to naturally move in the upward direction when gas is mixed during priming of the fluid.

(Prior Art 2)

In the invention described in the patent document 2 (Japanese Laid-Open Patent Publication No. 2011-30942), it is disclosed that a serpentine fluid flow path of the sheet heat exchanger described in Patent Document 1 can be formed more easily than the heat fusion processing. According to the invention, in the invention, the base plate on which the unevenness is formed is press-bonded to the bag-shaped sheet, and the convex portion and the concave portion form a flow path.

In other words, the base holding plate (symbol 14) and the cover holding plate (symbol 16) for holding the bag body (refer to the reference numeral 12 in Patent Document 2, the same applies hereinafter) form a concave-convex surface facing the bag body 12. shape. In the convex portion of the concavo-convex shape, the two sheets forming the bag body (reference numeral 12) are sandwiched and adhered to each other to form a flow path 38 which is curved in a portion corresponding to the concave portion. The internal space (reference numeral 24) of the bag body (reference numeral 12) is a simple shape such as a square when it is single, and is bent in the internal space 24 by being sandwiched by the holding plates (reference numerals 14 and 16). The flow path.

In a conventional medical heat exchanger, by using a snakelike shape or The plurality of bent portions form a fluid flow path having a folded portion to increase the length of the flow path and increase the amount of heat exchange (see FIG. 19). In this case, in order to promote degassing of air (gas) which is mixed in and retained in the flow path, the partition (surface) is inclined upward. However, in the case where the spacer is formed more in order to increase the amount of heat exchange, the length of the flow path is inevitably lengthened, and a stagnation portion is likely to be generated in the flow path, so that as a comprehensive degassing operation, It is not enough. When a gas is mixed in, during the movement of the mixed gas along the partition, the contact between the liquid and the heat source is lowered, and thus the integrated heat transfer (heat transfer) from the heat source to the liquid via the sheet layer (usually a synthetic resin sheet) The coefficient is reduced. It is therefore desirable to remove the gas in the sheet heat exchanger as quickly and fully as possible. In particular, in the initial stage of operation, it is necessary to thoroughly remove the gas in the apparatus (in the system) and rapidly remove the gas mixed or brought in during the operation.

However, the inventors of the present invention have reached a conclusion that a medical heat exchanger which simply tilts a plurality of spacers is conventionally used, and in order to ensure a sufficient heat exchange amount, the flow path is prolonged, and as a result, a gas is inevitably caused ( The residence time of the bubble) is increased, so that it is a difficult configuration to completely and quickly discharge the gas of the same gas out of the system.

More specifically, the conventionally known technique, that is, the invention described in the cited document 1-2, has the following problems.

The invention described in Patent Document 1 has the following problems.

(Question 1): In this configuration, when the gas is continuously mixed into the heat exchanger, since the gas moves along the fluid flow path 113FP (formed in a plurality of combinations in the vertical direction), the contact area between the fluid and the sheet becomes small. The heat exchange efficiency is deteriorated.

(Question 2): Since the gas passes through the fluid flow path 113FP together with the fluid, an error occurs in the fluidity of the fluid, and the heat exchange efficiency is still deteriorated.

(Problem 3): Since the portion 113FPN having a narrow width of the fluid channel 113FP and the portion 113FPW having a wide width interact with each other, the length of the fluid channel 113FP is shortened, and there is a fear that heat exchange (heating) cannot be sufficiently performed.

(Question 4): Since the area of the partition portion 112P inside the heat exchanger (refer to the oblique line in the drawing) is large (approximate to the area of the fluid flow path 113FP), the dead space (the portion where no liquid flows) Increased, heat exchange efficiency is poor.

On the other hand, the invention described in Patent Document 2 can be exemplified as follows.

(Problem): In the same manner as the technical concept of the invention described in Patent Document 1, the gas moves along the fluid flow path 113FP together with the fluid, so that even if the gas is removed in the upper direction, the process is The heat exchange rate will still decrease.

[Heat exchanger 1]

First, the heat exchanger device 1 of the present invention will be described on the one hand with reference to the drawings (Figs. 1 to 18). The heat exchanger device 1 of the present invention is basically composed of a heat exchanger and a flow path closing member. The heat exchangers of the first to third embodiments are exemplified in a specific embodiment. 11', 11'''), and the flow path closing members (20, 20', 20A' of the first to third embodiments).

In the following description, in order to avoid complication of the symbols, in the first to third embodiments, the same reference numerals are used for the same or related members, and only the different members are denoted by different symbols.

Further, when a plurality of members are formed in one direction of the side portion S, a symbol indicating the directivity is described in the rear portion of the symbol of the display member. For example, in the "spacer portion 12P" of FIG. 1 and the like, the space portion P on the upper "U" side is referred to as "12PU", and the space portion P in the lower portion "D" is referred to as "12PD". Similarly, for example, in the "groove 12M" of FIG. 10 and the like, the groove on the "U" side of the upper end of the base end "PE" side is referred to as "12MPEU", and the upper side of the terminal "DE" side is referred to as "U" side. The slot is described as "12MDEU".

[Heat exchanger 11 (first embodiment)]

As illustrated in Fig. 1, the heat exchanger 11 has a heat exchanger body 12H.

The heat exchanger body 12H is formed with a plurality of spacers 12P in the longitudinal direction L direction, 12P, 12P, ....

The so-called "snake-like" fluid flow path 12FP is formed in the longitudinal direction L direction of the heat exchanger body 12H by the plurality of spacers 12P, 12P, 12P, .

The partition portion 12P is in one direction from the side portion S toward the other side portion in one direction [substantially perpendicular to the V direction] of the side portion S [from the upper U (lower D) direction toward the lower portion D (upper U ) Direction] erect.

Each of the partition portions 12P, 12P, 12P, ... is disposed in a space along the long side L direction with a space interposed therebetween.

This space is the above-described fluid flow path 12FP.

The partition portion 12P and the "snake-like" fluid flow path 12FP can be formed, for example, by welding two sheets. This welded portion is the spacer 12P.

Further, a plate-shaped member (or a sheet of one piece) in which the fluid portions 12FP of the spacers 12P, 12P, 12P, ... and "snake" are formed in advance may be closely adhered (thermally welded) or adhered to one piece. The sheet (or panel-like member) is formed in the like.

The partition portion 12P is formed to be substantially the same length in one direction from the side portion S toward the other side portion S [from the upper U (lower D) direction toward the lower portion D (upper U) direction).

The spacer 12P is arranged to be placed adjacent to the upper U side (denoted as the symbol "12PU") and to the lower D side (denoted as the symbol "12PD").

All of the upper end portions of the partition portion 12P on the U side are disposed on the upper portion of the heat exchanger body 12H so as not to be connected (not in contact). That is, the upper end portion of the partition portion 12P on the U side is the upper open portion 12OU. In other words, the upper opening portion 120U is an upper opening portion, and a part of the fluid rising from the lower side flows out from the opening portion. On the other hand, when air bubbles (gas bubbles) are mixed in the fluid, the gas also flows from the opening portion. Flows upward (in the direction of 12SL). Further, the upper opening portion 12OU (opening portion) can be closed (sealed) by the flow path closing member 21SP of the present invention.

The end portion on the lower portion D side of the partition portion 12P is alternately disposed in the lower portion of the heat exchanger body 12H, and the "non-connector" is disposed alternately (the D-side end portion does not contact the lower portion of the main body 12H (that is, the above-mentioned 12PU)) and " "Connector" (the D-side end is in contact with the lower portion of the body 12H (that is, the above 12PD)).

The U side of the upper portion of the heat exchanger body 12H is formed in one direction from the side portion S toward the other side portion S [the base end PE side to the terminal end DE] and toward the side portion S [the upper U side ] Tilt up 12SL. By forming the inclination 12SL in this way, it is ensured that the gas trapped by the large space 12LS described later is rapidly degassed toward the discharge port.

The angle θ of the inclination 12SL may be formed to be inclined by 5 to 30° with respect to the horizontal direction, preferably 10 to 20°. For example, when the angle θ is excessively larger than 30°, the fluid flow path 12FP in the long side L direction is shortened, and the heat exchange (heating) efficiency is lowered. On the other hand, if the angle θ is less than 5° which is too small, the above-described degassing effect cannot be sufficiently expected, which is not preferable.

A large space 12LS is formed between the inclination 12SL and the end of one side [upper U side] of the side portion S of the partition portion 12P. This large space 12LS is a gas trap portion ATS which will be described later.

The upper opening portions 12OU of the partition portions 12P, 12P, 12P, ... are all in communication with the large space 12LS. Therefore, the fluid flow path 12FP also communicates with the large space 12LS (via the upper opening portion 12OU).

The heat exchanger body 12H is provided with a fluid inlet, an outlet, and a fluid valve (clip), and a heat exchanger 1 is formed adjacent to the heat source (heater). One feature of the present invention is that an exhaust port 14 is also provided together with the fluid inlet 13FI and the fluid outlet 13FO. In more detail, the heat exchanger body 12H is tied in one direction of the side portion S [base end PE The fluid inlet 13FI is provided on the side and the upper U side.

Further, the heat exchanger body 12H is provided with a fluid outlet 13FO in one direction of the side portion S [terminal DE side and lower D side].

Further, the heat exchanger body 12H is provided with an exhaust port 14 in one direction of the side portion S [terminal DE side and upper U side].

The first clip C1 (see FIG. 2) is attached to the connecting pipe of the fluid outlet 13FO (the symbol is not specifically described).

Further, a second clip C2 (see FIG. 2) is attached to the connecting pipe of the exhaust port 14 (the symbol is not specifically described).

The first clip C1 and the second clip C2 may be externally mountable clips, manual stopcocks (ie, three-way stopcocks, etc.), and solenoid valves. The first clip C1 (or the second clip C2) may be directly attached to the fluid outlet 13FO (or the exhaust port 14), or a connecting pipe or the like may be installed near the fluid outlet 13FO (or the exhaust port 14). The connecting pipe is provided with a first clip C1 (or a second clip C2).

[Flow passage closing member 20 for heat exchanger (first embodiment)]

The flow path closing member 20 (hereinafter sometimes referred to simply as "flow path closing member 20") of the heat exchanger is in the longitudinal direction thereof by, for example, the flow path occluder 21SP (Fig. 3(B)), for example, as shown in Fig. 3 ( As shown in A), the upper opening portion 12OU of the fluid flow path 12FP is closed.

As illustrated in FIG. 3(B), the heat exchanger flow path closing member 20 (hereinafter simply referred to as "flow path closing member 20") has a movable portion 21 and a fixed portion 22.

In order to apply pressure (pressing) to the sheet-shaped heat exchanger 11 from both the front side and the back side, pressure can be uniformly applied, and it is preferable that the movable portion 21 and the fixing portion 22 use a so-called "substantially plate shape". .

Therefore, the movable portion 21 is also referred to as a "movable plate" (front side), and the fixed portion 22 is also referred to as a "fixed plate" (back side).

The movable portion 21 is provided with a flow path occluder 21SP in the longitudinal direction L direction in one direction [upper U side] of the side portion S.

The flow path occluder 21SP has a so-called "substantially protruding shape" (or (substantially protruding shape)).

By pressing (pressing) (giving "pressing force" by "pressurizing"), the movable portion 21 is moved in the direction of the fixed portion 22, except for one portion, that is, the space 12S near the fluid inlet 13FI (refer to FIG. 3). (A) and FIG. 4), the upper opening portion 12OU of the partition portion 12P is completely closed.

In the case of "pressurization" (giving "pressing force"), as the driving means DF of the movable portion 21, a bladder type, a spring type, a lock type or the like can be used. In short, as long as the "pressing force" capable of closing the upper U side of the fluid flow path 12FP by the flow path occluder 21SP can be given, either manual or automatic, no matter what. Further, electrical or electromagnetic means can be employed as the driving means.

Further, as another flow path closing member, the movable portion 21 itself or the mounting can be changed by using a shape change characteristic of a material such as a bimetal or a shape memory alloy which is generated by an external signal such as temperature or load. It is in the shape of the flow path occluder 21SP of the movable portion 21.

In other words, as the pressing force imparting function to the flow path occluder 21SP (the pressing force imparting function for closing the upper opening portion 12OU of the fluid flow path 12FP), it is also possible to control by utilizing the characteristics of the material itself (by servo The mechanism controls the position of the flow path occluder 21SP and/or its opening and closing angle.

[heat source (heater) 23]

The heat source (heater) 23 may be disposed adjacent to the heat exchange portion 12HE of the heat exchanger body 12H.

That is, in the case where the heat exchanger body 12H is formed by overlapping the two sheets, the fluid can be heated to the target temperature by installing a heat source (heater) 23 on one side or both sides of the sheet.

The heat source (heater) 23 may have any configuration as long as it is in a form (shape, structure) that is closely attached or easily attached to the sheet body (heat exchanger body 12H). For example, any one of usual heat sources selected from the group consisting of a heating wire, carbon, ceramic, far infrared, oil, warm water, warm air, Peltier element, heat pipe, dielectric heating, and induction heating can be used.

[Manufacturing Method of Heat Exchanger 11]

An example of a method of manufacturing the heat exchanger 11 of the present invention in the first embodiment will be described.

(a) [Formation of two sheets]

The two sheets for forming the heat exchanger body (housing) are prepared, and the tubular members are used to form the fluid inlet 13FI, the fluid outlet 13FO, and the exhaust port 14 respectively as shown in FIG. 1 or FIG. The tubular member is sandwiched between the two sheets (as the heat exchanger body 12H) by a predetermined mold (not necessarily shown) and by high frequency, heat, ultrasonic, laser, or the like. The method welds the outer periphery of the sheet body and the inner side (a plurality of parts) of the sheet body.

The tubular member (the member forming the fluid inlet 13FI, the fluid outlet 13FO, and the exhaust port 14) is disposed between the two sheets (the heat exchanger body 12H) as shown in FIG. 1 or FIG. .

In addition, on the inside of the two sheets (heat exchanger body 12H), a plurality of The portion where the linear welding is performed is a plurality of spacers 12P, 12P, 12P, ... (see Fig. 1 or Fig. 2).

A "snake-shaped" fluid flow path 12FP is formed between the plurality of spacers 12P, 12P, 12P, ... as shown in Fig. 1 or Fig. 2 .

A fluid transfer pipe as a connection pipe is connected to each of the fluid inlet 13FI, the fluid outlet 13FO, and the exhaust port 14 (the symbol is not specifically described).

The liquid transfer pipe on the fluid outlet 13FO side is provided with the first clamp C1, and the liquid transfer pipe on the exhaust port 14 side is provided with the second clamp C2.

The material of the sheet body and the tubular member is, for example, not particularly limited, but preferably, it is polyvinyl chloride, polyethylene, polypropylene, polyamide, polyurethane, polyethylene terephthalate or the like. A synthetic resin commonly used in the medical field.

(b) [In the case of a panel-like member]

The heat exchanger body may be formed of a panel-like member having a partition portion and a single sheet body instead of using two sheets.

The panel-shaped member can be formed into a desired shape by melt-mixing the above-exemplified synthetic resin by a known molding method, for example, injection molding, compression molding, and cutting molding.

As shown in Fig. 1 or Fig. 2, the tubular member (fluid inlet 13FI, fluid outlet 13FO, and exhaust port 14) is integrally formed in the panel-like member.

Further, as shown in Fig. 1 or Fig. 2, a plurality of spacers 12P, 12P, 12P, ... are integrally formed in the panel-like member to form a "snake shape" between the plurality of spacers 12P, 12P, 12P, ... The fluid flow path 12FP. On the pressing surface side (front side) of the panel-shaped member, the sheet body is driven by means of high frequency, heat, ultrasonic wave, laser or the like. The outer circumference is closely attached or welded.

Further, the tubular member (the fluid inlet 13FI, the fluid outlet 13FO, and the exhaust port 14) may not be integrally formed, but may be welded to the panel-like member by the above means.

[Use (operation) method of [heat exchanger 1 (including heat exchanger 11 (first embodiment) and heat exchanger flow path closing member 20 (first embodiment))]

Hereinafter, an example of a method of using the heat exchanger device 1 will be described.

[Priming]

(1) The first clamp C1 (fluid outlet) is closed, and the second clamp C2 (exhaust port) is opened, and a fluid such as dialysate flows into the heat exchanger body 12H from the fluid inlet 13FI.

(2) By flowing the fluid, the gas in the body is released from the exhaust port 14 by extrusion, and the fluid is filled in the heat exchanger body 12H on the other hand.

In the present invention, since the upper portion U of the heat exchanger body 12H is not horizontally as is conventionally formed, but the inclination 12SL which gradually rises toward the exhaust port is formed, the gas rapidly rises along the inclination 12SL and does not occur. The heat exchanger body 12H is internally stopped by the exhaust port 14 together with the fluid.

[Formation of air trap ATS]

(3) As illustrated in Fig. 3, in the upper open portion 12OU of the meandering fluid flow path 12FP, the flow path occluder 21SP (movable portion 21) is pressed (pressurized) in the direction of the arrow Z by the flow path Pressing at the front end of the occluder 21SP, the two sheets having the flow path formed by the gap separation arrangement are closely adhered to the portion of the flow path occluder 21SP (projected in the L direction), thereby forming Flow path formed by the gap between two sheets Closed. That is, as shown in Fig. 3(A), the upper opening portion 12OU (upper opening portion) is completely closed except for the portion (near the fluid inlet). In this manner, the upper opening portion 12OU of the fluid flow path 12FP can be completely closed, and the upper opening portion 12OU is completely closed except for the space 12S (see FIGS. 3(A) and 4) of one portion (near the fluid inlet 13FI).

On the other hand, the large space 12LS on the U side of the upper portion of the heat exchanger body 12H that communicates with the upper opening portion 12OU is separated from the opening portion 12OU by the pressed occluder 21 to form the air trap portion ATS.

The original upper opening portion 12OU of the heat exchanger body 12H is on the lower D side, and serves as a heat exchange portion 12HE (see a frame portion of a broken line in Fig. 3).

Further, of course, it is needless to say that the fluid flow path 12FP is serpentine, and the fluid flows through the meandering fluid flow path 12FP in a stable state.

[Flow of Fluid When Heat Exchange (Heating) by Heat Exchanger Body 12H]

(4) When the first clamp C1 is opened and the second clamp C2 is closed in the state in which the above operation is completed, the fluid can be heated and flowed on the one hand in the meandering fluid flow path 12FP. The fluid that has entered the heat exchanger body 12H is sufficiently heat-exchanged along the meandering fluid flow path 12FP (as shown in FIG. 3(A), the fluid flow path 12FP does not become pressed by the occlusion device 21SP that is pressed and adhered. The closed flow path is diverted on the way, and the closed flow path is all in contact with the heat source (the portion surrounded by the broken line), so that sufficient heat exchange can be performed.

Further, in the present invention, even if gas enters the meandering fluid flow path 12FP, the flow path occluder 21SP is temporarily opened, and the upper portion 12OU (opening portion) of the upper portion of the heat exchanger body 12H is reappeared. The upper open portion 12OU allows all of the gas in the fluid flow path 12FP to be removed (or rapidly). Thus, after the gas is removed in a short time, the flow path occluder 21SP can be again Shutdown returns to the operation of the heat exchange operation with the fluid in a steady state. Thereby, the upper opening portion (i.e., the fluid branching portion) of the fluid flow path 12FP in the middle of the flow path disappears, and the fluid flow path 12FP becomes a flow path continuing to the outlet. Therefore, in the heat exchanger of the present invention, it is ensured High heating rate in steady state (no gas incorporation).

(5) Further, for the sake of caution, the mechanism of gas removal will be described. Since the gas is mixed in the upper direction even if a gas is mixed in the middle, the gas moves to the air trap portion ATS. In the case where a gas is mixed in the inflowing fluid, since the gas floats in the upper U direction, the gas flows from the fluid inlet 13FI toward the upper U direction, and is stored along the inclination 12SL on the U side formed above the flow path occluder 21SP. Air trap portion ATS.

(6) If it is appropriate to open the second clamp C2, the gas can be discharged from the exhaust port 14. When the gas trap portion ATS is filled with gas, the second clip C2 can be appropriately opened to discharge the gas.

(7) When the gas is introduced into the meandering fluid flow path 12FP, if the flow path occluder 21SP is temporarily opened, the gas can be naturally discharged from the upper opening portion 12OU to the air trap portion ATS.

[Linking control of each component by the control unit CPU]

The heat exchanger device 1 of the present invention includes a heat exchanger 11 (first embodiment) and a heat exchanger channel closing member 20 (first embodiment), and includes a second embodiment and a third embodiment which will be described later. The same is true. For example, as illustrated in FIG. 5 (block diagram), the control unit CPU can automatically perform interlocking control of driving of each member or the like.

(A) The control unit CPU controls opening and closing of the first clip C1 and the second clip C2.

(B) The control unit CPU controls the driving of the driving means DF (the above-described airbag type, spring type, lock type, etc.) of the movable portion 21.

(C) The control unit CPU controls the heat source 23 (the above-mentioned heating wire, carbon, ceramic, far infrared ray, oil, warm water, warm air, Peltier element, heat pipe, and medium) that are not adjacent to the heat exchange unit 12HE. The temperature of electric heating, induction heating, etc.).

The heat source 23 can change the shape of the flow path occluder 21SP (the above-described bimetal, shape memory alloy, etc.) installed in the movable portion 21.

Further, in the case of the heat exchanger 11, as shown in Fig. 6, each of the connection pipes (liquid transfer pipes) which can be connected to the fluid inlet 13FI is provided with a liquid inflow pump PI and a connection pipe (liquid transfer pipe) at the fluid outlet 13FO. A liquid discharge pump PG is installed in the connection pipe (liquid transfer pipe) in which the liquid flows out of the pump PO and in the exhaust port 14.

(D) The control unit CPU controls the driving of the liquid inflow pump PI, the liquid outflow pump PO, and the gas discharge pump PG, and automatically controls the heat exchange of the fluid by the above-described priming and heat exchanger body 12H on the one hand ( heating).

As shown in FIG. 5, the heat exchanger device 1 can be installed in a flow path closed by a sensor selected from the liquid level sensor LS, the gas sensor AS, and the temperature sensor TS or a combination thereof. The movable portion (21, 21', 21A') or the fixed portion (22, 22', 22A') of the member (20, 20', 20A') (or a suitable portion of the heat exchanger body or the like). As the liquid level sensor LS and the gas sensor AS, a well-known ultrasonic sensor, a microwave sensor, a near-infrared sensor, a photoinductor, or the like can be used as a temperature sensor, and it is suitable for use. Temperature resistance sensor, thermocouple sensor, thermistor, etc., of course, are not limited to these.

(E) As shown in FIG. 5, the control unit CPU is connected to one or a combination selected from the group consisting of a liquid level sensor LS, a gas sensor AS, and a temperature sensor TS, and performs the above-described (A) ~ (D) control.

[How to use the heat exchanger device 1 using the control unit CPU]

Hereinafter, an example of the method of use (operation method) will be described.

[Priming]

(1) closing the first clamp C1, opening the second clamp C2, and causing the liquid to flow into the pump PI (Fig. 6) to operate so that the fluid (dialysis solution) flows from the fluid inlet 13FI into the heat exchanger body 12H (as explained The air (gas) in the system (inside the device) is squeezed and discharged by the inflowing fluid.).

(2) The gas discharge pump PG is operated to degas the gas from the exhaust port 14 on the one hand, and fill the fluid in the heat exchanger body 12H on the other hand.

(Formation of air trap ATS)

(3) After the liquid level sensor LS detects that the heat exchanger body 12H is filled with a predetermined amount of liquid, the driving portion DF is operated, as illustrated in Fig. 3, on the meandering fluid flow path 12FP. The opening portion 12OU presses (presses) the flow path occluder 21SP to close the upper opening portion 12OU of the fluid flow path 12FP. The upper open portion 12OU is completely closed except for the space 12S near the fluid inlet 13FI (in addition, although the U-side upper large space 12LS communicates with the upper open portion 12OU, the pressurization and close-coupled occluder 21SP explicitly both Isolate into 2 areas.).

The large space 12LS on the U side of the upper portion of the heat exchanger body 12H serves as the air trap portion ATS.

The original upper opening portion 12OU of the heat exchanger body 12H (now closed) is on the lower D side (in the frame of the broken line in Fig. 3), and becomes the heat exchange portion 12HE (see the frame portion of the broken line in Fig. 3).

The fluid flow path 12FP is serpentine (the upper open portion 12OU is closed, and the split flow is continuous to the outlet). The fluid then flows through the meandering fluid flow path 12FP.

[Flow of Fluid When Heat Exchange (Heating) by Heat Exchanger Body 12H]

(4) When the first clip C1 is opened and the second clip C2 is closed, the fluid can be heated while flowing in the meandering fluid flow path 12FP. In this way (in the steady state in which the occluder 21SP is closed), a long flow path for the fluid to meander is formed, so that the fluid flowing in from the 13FI can be sufficiently cooled to a sufficient retention time τ from the discharge of the 13FO, and can be easily heated to the place. The temperature of hope.

In this state, the heating operation is performed by heating the heat source 23 and heating the heat exchanger body 12H.

The fluid flowing into the heat exchanger body 12H, on the one hand, flows along the meandering fluid flow path 12FP on the one hand and is heat exchanged. The temperature of the liquid can be sensed by the temperature sensor TS, and the heat source 23 is, for example, subjected to ON/OFF control by the detected temperature, thereby being adjusted to a suitable temperature (set temperature).

On the other hand, when the gas intrudes (mixes in) into the meandering fluid flow path 12FP, the bubble sensor (gas sensor) AS detects the drive unit DF in the opposite direction, and temporarily flows. The road occluder 21SP is opened, and all the gas in the fluid flow path 12FP can quickly rise through the open portion 12OU and be trapped by the large space 12LS that is reconnected, thereby being removed from the exhaust port 14.

(5) In this way, even if the gas is mixed in the middle, the gas moves to the air trap portion ATS by temporarily opening the flow path occluder and the gas has a property of floating upward in the U direction (that is, the gas is mixed in the inflowing fluid). In the case of a gas, since the gas floats upward in the direction of the upper U, the gas flows from the fluid inlet 13FI toward the upper U direction, along the inclination 12SL. The gas trap portion ATS formed on the U side of the upper portion of the flow path occluder 21SP is stored. ).

(6) In the steady state, the flow path occluder 21SP is closed, but it is assumed that the gas trap portion ATS is filled with gas in this state. In this case, the gas can be self-contained as long as the second clamp C2 is appropriately opened. The exhaust port 14 is exhausted.

(7) Further, in the case where the gas is introduced into the meandering fluid flow path 12FP, if the gas sensor AS is used again for sensing, and the flow path occluder 21SP is temporarily opened, the gas can be naturally ventilated. The well portion ATS is discharged.

[Heat exchanger 11' (second embodiment)]

Fig. 7 is a schematic view showing a heat exchanger 11' of the second embodiment.

As described above, in the heat exchanger 11 of the first embodiment (see Fig. 1), the exhaust port 14 is disposed in one direction of the side portion S of the heat exchanger body 12H [terminal DE side and upper U side] . Therefore, one direction [upper U side] of the side portion S of the heat exchanger body 12H is formed in one direction from the side portion S toward the other side portion S [from the base end PE side toward the terminal DE side] And the inclination 12SL which rises toward one direction [upper U side] of the side portion S.

However, the position (installation) position of the exhaust port 14' may be formed in one direction from the side portion S toward the other side in the one direction [upper U side] of the side portion S of the heat exchanger body 12H. Any position between one side of the side S [from the base end PE side toward the terminal DE side].

(position position of exhaust port 14')

For example, in the heat exchanger 11' (second embodiment) shown in Fig. 7, the exhaust port 14' is disposed in one direction (upper U side) of the side portion S of the heat exchanger body 12H', and is disposed on the side. The approximate middle position of one direction S [long side L direction]. Therefore, one direction [upper U side] of the side portion S of the heat exchanger body 12H' is formed from one direction of the side portion S toward the other direction [from the base end PE side toward the terminal DE side] and toward the side portion S The first inclination 12SL1 in which the one direction [upper U side] rises and the second inclination 12SL2 which decreases from one direction of the side portion S toward the other side portion S [from the first inclination 12SL1 toward the terminal DE side] .

Further, the upper U side of the heat exchanger body 12H' is the first inclination 12SL1 rising from the fluid inlet 13FI of the base end PE toward the exhaust port 14' of the upper U side, and the exhaust from the upper U side. The port 14' is formed by the second inclination 12SL2 which is lowered toward the terminal DE side.

[Heat exchanger 11'" (third embodiment)]

Fig. 16 is an overall view of the heat exchanger 11''' (third embodiment) as seen from the front direction.

As illustrated in Figure 16, the heat exchanger 11"" has a heat exchanger body 12H"".

The heat exchanger body 12H''' is formed in one direction of the side portion S [the long side L direction (substantially perpendicular to the V direction, from the upper U direction toward the lower portion D direction)] is formed with a plurality of spacers 12P, 12P, 12P, ... .

The plurality of spacers 12P, 12P, 12P, ... form a so-called "snake-shaped" fluid flow path 12FP in one direction [long side L direction] of the side portion S of the heat exchanger body 12H'".

The partition portion 12P is erected so as to rise from one direction of the side portion S toward the other side portion S (the side from the first side portion S1 side toward the second side portion S2 side).

The angle θ of inclination is formed to be inclined by 5 to 30°, preferably 10 to 20° with respect to the horizontal direction, similarly to the heat exchanger 11 (first embodiment).

Each of the partition portions 12P, 12P, 12P, ... is disposed in a space along the long side L direction with a space interposed therebetween.

This space is the fluid flow path 12FP.

The partition portion 12P and the "snake-like" fluid flow path 12FP can be formed in the same manner as the heat exchanger 11 (first embodiment).

The plurality of spacers 12P, 12P, 12P, ... are formed in one direction from the side S toward the other side S (from the first side S1 side toward the second side S2 side). The same length.

In addition, the spacers 12P, 12P, 12P, ... are formed closer to the first side portion S1 side (described as the symbol "12PS1") and closer to the second side portion S2 side (described as the symbol "12PS2") ) Interactive configuration.

The end portions on the second side portion S2 side of the partition portions 12P, 12P, 12P, ... are all disposed on the second side portion S2 side of the heat exchanger body 12H so as not to be connected (not in contact). In other words, the second side opening portion 12OS2 is formed closer to the second side portion S2 side of the partition portion 12P.

On the other hand, the end portions on the first side portion S1 side of the partition portions 12P, 12P, 12P, ... are "unconnected" (not in contact) (the above 12PS2) and "connected" (contacted) (the above) Each of 12PS1) is alternately arranged on the first side portion S1 side of the heat exchanger body 12H'''. Thereby, the flow direction of the fluid becomes substantially opposite directions.

A large space 12LS is formed between the second side portion S2 side of the heat exchanger body 12H''' and the second side portion S2 side of the partition portion 12P. The large space 12LS is the air trap portion ATS.

The second side opening side (opening) 12OS2 of the partition portion 12P communicates with the large space 12LS, and all of the fluid flow path 12FP communicates with the large space 12LS.

The heat exchanger body 12H''' is provided with a fluid inlet 13FI in one direction of the side portion S [the base end PE side and the first side portion S1 side]. Further, the heat exchanger body 12H''' is provided with a fluid outlet 13FO in one direction of the side portion S [terminal DE side and first side portion S1 side]. Further, the heat exchanger body 12H''' is provided with an exhaust port 14 in one direction of the side portion S [the terminal DE side and the second side portion S2 side].

The first clip C1 and the second clip C2 are the same as those of the heat exchanger 11 (first embodiment), and can be similarly mounted.

In the same manner as the heat exchanger 11 (first embodiment), the heat exchanger flow path closing member 20 (see FIG. 3) can be installed in the heat exchanger 11''', and can be used as shown in FIG. The flow path closing member 20 for the heat exchanger is substantially the same as that of the first embodiment.

Hereinafter, the operation method will be briefly described.

(Priming)

(1) The first clip C1 attached to the connecting pipe of the fluid outlet 13FO is closed, and the second clamp C2 attached to the connecting pipe of the exhaust port 14 is opened to allow the fluid to flow from the fluid inlet 13FI into the heat exchanger body 12H.

(2) The gas ejected by the inflowing fluid, on the one hand, degassing from the exhaust port 14, on the one hand, filling the fluid in the heat exchanger body 12H''.

The spacer portion 12P is raised from the first side portion S1 side toward the second side portion S2 side. At the inclination, the gas does not stagnate inside the heat exchanger body 12H'" and is removed from the exhaust port 14 together with the fluid.

[Formation of air trap ATS]

(3) As shown in Fig. 17, the second side opening portion 12OS2 of the meandering fluid flow path 12FP presses (presses) the flow path occluder 21SP to open the second side of the fluid flow path 12FP. The part 12OS2 is closed. The second side opening portion 12OS2 is the same as the case shown in Fig. 12, and is completely closed except for the space 12S of one portion [lower D side]. That is, the connection of the 12OS2 to the large space 12LS is blocked by the 21SP.

The large space 12LS on the second side portion S2 side of the heat exchanger body 12H''' serves as the air trap portion ATS.

According to the first embodiment, it can be understood that the original second side opening portion 12OS2 to the first side portion S1 side of the heat exchanger body 12H''' serves as the heat exchange portion 12HE. The fluid flow path 12FP is serpentine in the same manner as in the first embodiment. The fluid is formed by flowing through the meandering fluid flow path 12FP.

[Flow of fluid when heat exchange (heating) is performed by heat exchanger body 12H'"

(4) After the completion of the priming, if the first clip C1 attached to the fluid outlet 13FO is opened and the second clip C2 attached to the exhaust port 14 is closed, it can be in the meandering fluid flow path 12FP ( In the state in which the second side opening portion 12OS2 is closed by the flow path occluder 21SP, the fluid is heated on the one hand to flow therethrough. The fluid entering the heat exchanger body 12H, on the one hand, flows along the meandering fluid flow path 12FP on the one hand and is sufficiently heat exchanged (heated).

(5) Furthermore, even if there is gas invading the serpentine fluid flow path 12FP, as long as it is temporary The flow path occluder 21SP is opened, and all the gas in the fluid flow path 12FP can be removed at the same time, which is the same as in the first embodiment and the like.

More specifically, since the gas has a property of floating in the upper U direction even if a gas is mixed in the middle, the gas moves to the air trap portion ATS. When a gas is mixed in the inflowing fluid, since the gas floats in the upper U direction, the gas flows from the fluid inlet 13FI toward the upper U direction, and is stored in the flow path occluder 21SP along the inclination 12SL of the partition portion 12P. The air trap portion ATS on the second side portion S2 side.

(6) In this state, the gas can be discharged from the exhaust port 14 as long as the second clip C2 (installed in the exhaust port 14) is appropriately opened. Further, when the gas trap portion ATS is filled with gas, the second clip C2 can be appropriately opened to discharge the gas.

(7) When the gas is introduced into the meandering fluid flow path 12FP, as described above, when the flow path occluder 21SP is temporarily opened, the gas can be naturally discharged to the air trap portion ATS.
