Description

  The present invention relates to an all-plastic resin radiator capable of room heating by hot water circulation and room cooling by cold water circulation, and is a heating / cooling radiator suitable for concealment arrangement in a partition of a building.

A heat radiator in which the hot water circulation heat radiating portion is made of plastic has already been proposed by Conventional Example 1 shown in FIG. 5, Conventional Example 2 shown in FIG. 6, and Conventional Example 3 shown in FIG.
Conventional Example 1 (FIG. 5) is a hot water circulation radiator disclosed in Patent Document 1, and FIG. 5 (A) is a heat radiating part by bending and extending one of plastic pipes. , (B), a plurality of pipes are arranged in parallel and both ends are connected by a socket, a forward pipe is connected to the upper end of the socket at one end, a return pipe is connected to the lower end of the socket, and the return side pipe is connected to the return side pipe. The hot water is circulated through all the pipes to the pipe, (C) is an explanatory view of the flowing water of the socket part, and (D) is a perspective view of the socket part.

Further, Conventional Example 2 (FIG. 6) is cited as Patent Document 2, and the present inventors have developed two radiator panels developed as radiators suitable for a hot water circulation heater for floor mounting. 6A is a front view of the first heat dissipation panel side, FIG. 6B is a left side view of the heat sink, and FIG. 6C is a right side view of the heat dissipation portion. (D) is a front view for the back side, that is, the second heat radiation panel side.
That is, as shown in FIG. 6 (A), the first heat radiating panel is integrated with the vertical pipe group between the upper and lower horizontal pipes, and the vertical pipe tip is fitted into the insertion hole of the horizontal pipe and thermally integrated. The ends of the upper and lower horizontal pipes are closed with a closing plate, and the supply port projects downward from one end (right end) of the lower horizontal pipe.

In addition, as shown in FIG. 6 (D), the second heat radiating panel is integrated with the vertical pipe group between the upper and lower horizontal pipes, and the vertical pipe tip is fitted into the insertion hole of the horizontal pipe and thermally integrated. The end of the upper and lower horizontal pipes is closed with a closing plate, and at the other end (left end) of the upper horizontal pipe, a partition plate is arranged while maintaining one vertical pipe from the closing plate, and one end (right end of the lower horizontal pipe) ), The partition plate is disposed while maintaining one vertical pipe from the closing plate, and the discharge port is disposed below between the closing plate and the partition plate.
Then, as shown in FIG. 6 (B), the first heat radiating panel and the second heat radiating panel are connected by connecting pipes between the horizontal pipe ends on the upper left side (the other end) and between the horizontal pipe ends on the lower side. Are connected by a spacer pipe, and the upper and lower sides of the right end (one end) are connected by a spacer pipe between the ends of the horizontal pipe.

  Therefore, as shown in FIG. 6, the hot water supplied from the supply port at the lower end of the first heat radiating panel is f1 flow at the supply port → left f2 flow in the lower horizontal pipe → upward f3 flow of the vertical pipe group → upper side. Left side f4 flow of horizontal pipe → f5 flow from the first heat dissipating panel to the second heat dissipating panel in the communication pipe → left end vertical pipe by the closing plate and partition plate at the other end (left end) of the upper horizontal pipe of the second heat dissipating panel Downward f6 flow in the right row f7 flow to the partition plate of the lower horizontal pipe → Upward f8 flow of the vertical pipe group → Right row f9 flow from the partition plate of the upper horizontal pipe to one end (right end) in the vertical pipe The descending f10 flow → the f11 flow from the discharge port, and the hot water circulates in the two panels in the form of multiple layers.

  In addition, Conventional Example 3 (FIG. 7) was developed by the inventor of the present invention as a hot / cold water circulation radiator suitable for concealment arrangement in a partition of a building, and is cited as Patent Document 3, This is an all-plastic resin heatsink in which two heat dissipation panels are integrated, with (A) showing a partial cross-sectional plan view of the header and (B) showing the relationship between the header and the vertical pipe. FIG. 4C is a partially enlarged plan view of the heat dissipation panel.

In other words, Conventional Example 3 (Fig. 7) is prepared by injection molding a header that protrudes in parallel with a branch pipe group with a medium diameter (17 mm) from the large diameter (27 mm) header main pipe to the side with a center distance of 20 mm. A vertical pipe 2C group having a small diameter (13 mm) is connected between the upper and lower headers to form an all-plastic resin heat dissipating panel, and the two heat dissipating panels are connected and integrated in a multilayered structure to form a heat radiator. .
The connection between the header and the vertical pipe group is made by manually fitting the ends of the vertical pipes one by one into the mounting hole located at a depth of 10 mm from the tip on the inner periphery of the joint pipe for the header. The outer periphery of the joint branch pipe is melted by a heating tool, and the joint branch pipe and the insertion vertical pipe in the outer peripheral portion are fused.

JP 2001-116475 A JP 2009-192144 A Registered Utility Model No. 3163477

In the radiator of the conventional example 1 (FIG. 5), since the pipes are arranged in the horizontal direction, the resistance to flowing water is large, and when the number of pipes is large, each pipe is drifted and the temperature of the heat radiation surface is increased. It becomes inhomogeneous.
In addition, there are many fusion parts such as a fusion plate, a socket, a closing plate, and a pipe group, and the production is complicated, and the production work requires skill.

  In addition, the heat radiator of Conventional Example 2 (FIG. 6) is made of all plastic resin and integrates two layers of heat radiation panels excellent in radiant heat radiation, so it is lightweight and has excellent thermal efficiency. However, in order to obtain uniform heat dissipation over the entire surface, it is necessary to attach each vertical pipe group to the horizontal pipe without any distortion, and the uniform dense joint of the small diameter vertical pipe group to the large diameter horizontal pipe is It is a complicated and skillful task.

  In addition, the first heat radiating panel is provided with a supply port at one end (right end) of the lower horizontal pipe, and the second heat radiating panel is provided with a discharge port at one end (right end) of the lower horizontal pipe. Since the flow path changing partition plate is interposed between the vertical pipe and the leftmost vertical pipe, the structure of the first heat radiating panel is different from that of the second heat radiating panel. Is complicated.

Further, the radiator of the conventional example 3 (FIG. 7) has a branch pipe group for joints with an intermediate diameter (outer diameter of 17 mm) from the side of the header main pipe with a large diameter (outer diameter of 27 mm), a center distance of 20 mm, that is, a joint. It is complicated and expensive to manufacture a mold for injection-molding a header having a mounting hole having a depth of 10 mm from the tip of the joint branch pipe, with the interval between the branch pipes protruding at 3 mm.
In addition, the thickness of the joint branch pipe is limited in view of the flow-in effect of the molten resin in the mold, and there is a risk of nest formation at the joint between the joint branch pipe and the header main pipe. In order to avoid the risk of cracking due to heat stress and hydraulic load during use, the thickness reduction of the joint branch pipe is restricted.

Then, the fusion bonding of each vertical pipe to each joint branch pipe is a fusion joint obtained by covering and sandwiching the outer peripheral surface of each joint branch pipe with a pair of upper and lower heating tools (not shown). Even when aiming to increase the density of the vertical pipe group with the aim of increasing the heat dissipation of the pipe, the fusion interval of the branch pipes for each joint is the minimum necessary for inserting and interposing a pair of upper and lower heating tools (standard: 3 mm) ) Is required.
Therefore, in the radiator of the conventional example 3 (FIG. 7) in which a vertical pipe is inserted into the joint branch pipe and the vertical pipe is fused and integrated into the joint branch pipe, the fusion between the joint branch pipes is achieved. The vertical pipe is inserted into the joint branch pipe and fused and integrated under the minimum required size constraint of the wearing interval. It is larger than the interval (standard: 7 mm), and the maximum number of vertical pipes per unit width is limited to increase the heat generation of the radiator.

  The present invention is a heat radiator that is superior in function to the conventional example 3 (FIG. 7) and can be manufactured more rationally with a greater amount of heat radiation, which reduces the problem of the header injection mold. This is a new and highly practical heatsink made of all-plastic resin that has a smaller space between vertical pipes and can increase the amount of heat dissipation per unit area. Is to provide.

  In the present invention, as shown in FIG. 1, between the upper and lower headers 1 made of plastic resin, two pieces of first and second heat radiation panels, in which vertical pipes 2C made of plastic resin and having the same diameter and the same length are connected in close parallel, are connected. , An all-plastic resin radiator having an integrated communication in the form of a multi-layer, with a supply port 2S projecting at one end of one heat dissipating panel 101 and a discharge port 2R projecting at one end of the other heat dissipating panel 102, The header 1 is provided with a group of mounting holes Ha on the side surface of the large-diameter main pipe 2A, and a small-diameter joint branch pipe 2B group is fitted and welded to each mounting hole Ha so as to protrude sideways in parallel. The upper and lower ends of the vertical pipe 2C are fitted and heat-sealed to the outer periphery of each joint branch pipe 2B of the header 1, and the vertical pipe 2C group communicates with the upper and lower headers 1. It is a vessel.

  In this case, the header 1 main pipe 2A, the joint branch pipe 2B, and the vertical pipe 2C may be made of a thermoplastic resin that can be heat-sealed to each other. Typically, polypropylene, random, copolymer resin (PP- As shown in FIG. 2, the main pipe 2A has an outer diameter dA of 27 mm, a wall thickness tA of 5 mm, and has a fitting hole step portion hb for fitting and fixing the small-diameter joint branch pipe 2B. The length L1 is 362 mm, the joint branch pipe 2B is provided with the mounting hole Ha group provided on the side, the outer diameter dB is 9.8 mm, the wall thickness tB is 1.0 mm, and the mounting hole Ha of the main pipe 2A. The vertical pipe 2C has an outer diameter dC of 13 mm and a wall thickness tC of 1.6 mm, and is fitted and integrated with the outer periphery of the upper and lower branch pipes 2B. The exposed length h2 is 1946 mm.

  The header 1 is for a small-diameter short joint that can be prepared by extrusion molding for a main pipe 2A (standard: outer diameter 27 mm, wall thickness 5 mm) of a large-diameter injection molded product having mounting holes Ha on the side surface. Since the branch pipe 2B is constructed by fitting and fusion integrated, a simple and inexpensive injection mold can be used to prepare a homogeneous header and the mounting hole Ha of the header main pipe 2A can be arranged freely. The arrangement interval of the groups is the minimum fusion interval at which a pair of upper and lower welding heating tools (not shown) can sandwich the outer periphery of the vertical pipe 2C in a state where each vertical pipe 2C is fitted to the outer periphery of the joint branch pipe 2B. (3 mm), and the heat radiation amount per unit area of the heat radiator He can be maximized by concentrating the vertical pipe 2C group.

Note that the fusion interval can be minimized to a minimum of 3 mm by adopting a new heat fusion means (Japanese Patent Application No. 2010-152929) developed and proposed by the present applicant.
Therefore, in the radiator of Conventional Example 3 (FIG. 7), the fusion site is the outer periphery of the joint branch pipe fitted to the outer periphery of the vertical pipe. In the radiator He according to the present invention, the minimum possible distance between the vertical pipes is 7 mm, because the outer periphery of the vertical pipe 2C fitted to the outer periphery of the joint branch pipe 2B is fused. Even if the same vertical pipe 2C as the vertical pipe of Example 3 (FIG. 7) is adopted, the minimum possible distance between the vertical pipes 2C can be shortened to 3 mm, and the heat dissipation per unit area of the radiator He of the present invention is The amount of heat released was significantly improved from that of Conventional Example 3 (FIG. 7) (result of demonstration comparison experiment: 23.5% increase).

  Therefore, in the radiator of the present invention, the heat radiation and cooling efficiency per unit area are large because the heat radiation and cooling efficiency per unit area is large, with two layers of heat radiation panels consisting of all plastic pipe groups. It is subordinate (less than 30%) to circulate and heat the inside of the two heat dissipating panels 101 and 102, and to heat and heat the air around the heat dissipating panel. Strong) heating function, and the heat dissipation panel has a surface temperature (standard: 45 ° C) that does not cause burns even if it is touched by hand by circulating hot water (standard: 60 ° C). By providing a total with radiant heat, it provides gentle heating that is gentle on the human body.

Further, during cooling, if cooling water (standard: 14 ° C.) is circulated in the heat radiating panels 101 and 102, convection cooling and radiation, mainly radiant heat cooling, follow convective cooling heat transfer of air as in the heating operation. The total cooling will create a uniform temperature environment with no spots in the room.
The joint branch pipe 2B is short (standard length: 30 mm), and the mounting work of the header main pipe 2A to the mounting hole Ha is easy. The vertical pipe 2C is fitted to the outer periphery of the joint branch pipe 2B. Because it is easy to work, it can be carried out with simple manual work.

Moreover, the joint branch pipe 2B group has a holding function as well as a header function with respect to the vertical pipe 2C group, and thus guarantees a uniform flowing water function and durability of the vertical pipe 2C group.
And since it is made of all plastic resin, it is lightweight and has excellent manufacturing, transportation, and mounting workability, and can be arranged in a suspended form via the upper header 1, so that the space in the partition wall of the building, etc. It is possible to construct a concealed heating / cooling system in a narrow space.

Further, in the radiator of the present invention, the vertical pipe 2C group is arranged by repeating a plurality of blocks BP as shown in FIG. It is preferable that the inside is a minute interval gc and the blocks BP are arranged with a small interval gc ′ larger than the intra-block interval gc.
In this case, the intra-block interval gc is the minimum interval capable of heat-sealing with the joint branch pipe 2B of the vertical pipe 2C, and the inter-block interval gc ′ is a small interval having a function of promoting air convection. Specifically, the intra-block BP interval gc is 3 mm, and the inter-block BP interval gc ′ is 5 mm.
The number of vertical pipes 2C in one block BP may be determined from the number of all vertical pipes 2C and the size of the fusion processing tool, and is typically three.

Therefore, in the radiator He, the vertical pipes 2C of each block BP are in a dense (standard interval: 3 mm) parallel configuration, and air convection between the vertical pipes 2C is reduced, but an increase in heat generation can be achieved. The interval between the blocks BP (standard interval: 5 mm) promotes air convection between the space between the two heat dissipating panels and the outside of the heat dissipating panel.
Since the vertical pipe 2C group is arranged as a block BP unit, a pair of upper and lower fusing tools (not shown) can be made into short sized working tools corresponding to the block BP, and fusing by heating (standard: 210 ° C.). The fusion work is performed in a state where the thermal expansion of the processing tool can be ignored, and the vertical pipes 2C can be fused and integrated at intervals as designed.

  In addition, the space in the block BP (standard: 5 mm) is an interstitial gap for inserting a suspension fitting (not shown) for supporting the suspension of the header 1 between the vertical pipes 2C when the radiator He is used. Provided for the suspension arrangement of the heat radiator He having a width L1 (standard: 362 mm) and a long length h1 (standard: 2000 mm) of the present invention when applied in a narrow space such as in a partition wall. A locking space is also provided.

  Further, as shown in FIG. 4, in the radiator of the present invention, the first heat radiating panel 101 and the second heat radiating panel 102 close each end of the upper and lower header main pipes 2A with a closing plate 2F, and the first heat radiating panel 101. Then, the upper header main pipe 2A protrudes upward from the supply port 2S from one end, and a partition plate 2P is arranged between the first and second vertical pipes 2C from one end. The main pipe 2A protrudes upward from the discharge port 2R from one end, and a partition plate 2P is disposed between the first and second vertical pipes 2C from the other end, and both heat radiation panels 101 and 102 are connected to the upper header main pipe 2A. It is preferable that the other end is communicated by a communication pipe 2D, and one end of the upper header main pipe 2A and the both ends of the lower header main pipe 2A are fixed by a spacer pipe 2E.

  In this case, as the supply port 2S and the discharge port 2R, a pipe piece obtained by cutting the vertical pipe 2C material into a short size (standard: 50 mm) may be adopted. The first heat radiation panel 101 and the second heat radiation panel 102 have a structure. As shown in FIG. 4, since only the arrangement positions of the supply port 2S and the discharge port 2R are different, a heat radiation panel body having the same structure is prepared for mass production, and the supply port 2S or the discharge port 2R to the upper header main pipe 2A is prepared. The first heat dissipating panel 101 and the second heat dissipating panel 102 can be prepared by sorting the mounting positions of the right end and the left end, and when the two layers 101 and 102 are integrated with each other, the supply port 2S and the discharge port 2R However, they may be integrated so as to be before and after the same position.

  Further, the first heat radiating panel 101 and the second heat radiating panel 102 have four corners, that is, both ends of the upper header main pipe 2A and both ends of the lower header main pipe 2A at one corner as a communication pipe 2D, and at the other three corners as a spacer pipe 2E. However, the space between the two heat dissipating panels 101 and 102 can be arranged in a narrow space, for example, in a partition wall of a building, etc. Preferably, the radiator typically has a total height h1 of 2000 mm, a vertical pipe exposure length h2 of 1946 mm, a thickness W1 of 58.5 mm, a first heat dissipating panel 101 and a second heat dissipating panel 102, as shown in FIG. The gap gs between the header main pipes 2A is 4.5 mm allowing a minimum air flow, and the panel surface gap gp is 18.5 mm.

  Therefore, the radiator of the present invention is mass-produced with two heat radiating panels having the same structure before the supply port 2S and the discharge port 2R are attached, as shown in the front view (B) and the rear view (D) of FIG. Prepare two heat dissipating panels by attaching the supply port 2S to the right end of the header main pipe 2A as the first heat dissipating panel 101 and attaching to the left end of the header main pipe 2A of the discharge port 2R as the second heat dissipating panel 102. Since the heat radiation panel 101 and the second heat radiation panel 102 can be produced simply by integrating them at the four corners in a multi-layered form in which the supply port 2S and the discharge port 2R are front and rear at the same position, Preparation can be streamlined.

  And the obtained heat radiator is the supply flow f1 of the warm water for heating from the supply port 2S of the one end (right end) of the 1st heat radiating panel 101, or the cooling water supply flow f1 in the right end vertical pipe. Cross flow f3 in side main pipe 2A → upward flow f4 in vertical pipe → cross flow f5 in upper main pipe 2A → communication flow f6 into second heat radiating panel 102 in communication pipe 2D → left end vertical pipe in second heat radiating panel The first heat radiating panel circulates in the path of the inner descending flow f7 → the cross current f8 in the lower main pipe 2A → the simultaneous upflow f9 in the vertical pipe → the cross current f10 in the upper main pipe 2A → the discharge flow f11 at one end (right end) of the radiator. Since the upper main pipe 2A is always filled with the simultaneous upward flow f4, f9 of the vertical pipe group, both the 101 and the second heat radiating panel 102 are filled with air in the upper end position, that is, the upper header main pipe 2A. It becomes a heatsink that does not generate.

  Therefore, the radiator has a narrow front and rear width W1 and is a radiator with excellent thermal efficiency mainly using radiant heat radiation during heating or cooling, and is suitable for hanging arrangement in a narrow space such as in a partition wall space of a building. In addition, the radiator He itself has hot water or cooling water for the ceiling pipe, the forward pipe S as the radiator supply port 2S, and the return pipe R as the radiator outlet 2R. Connected, both ends of the upper header main pipe 2A can be supported in a suspended form by suspension fittings (not shown), and are arranged in a concealed form in the space in the partition wall of the building, exhibiting high thermal efficiency mainly with radiant heat This makes it possible to build a heating / cooling system that does not require air bleed maintenance.

Since the radiator of the present invention is made of all plastic resin, it is lightweight and easy to manufacture, transport, and mount.
In addition, since the header main pipe 2A has a single structure, the injection mold can be manufactured inexpensively and easily, and the header main pipe 2A having a uniform and high quality can be manufactured.
Since the fitting of the small-diameter joint branch pipe 2B into the header main pipe mounting hole Ha and the fitting of the medium-diameter vertical pipe 2C to the outer circumference of the joint branch pipe 2B can be easily performed manually, Guaranteed heatsink becomes easy.

Moreover, since the vertical pipe 2C group constituting the heat radiating surface is fitted to the outer periphery of each joint branch pipe 2B group of the header 1 and is heat-sealed, each vertical pipe 2C is spaced at a minute interval (standard: 3 mm). Closely parallel arrangement increases heat dissipation.
And the branch pipe 2B group for joints covered with the vertical pipe 2C group plays the holding function of the vertical pipe 2C, guarantees the uniform water flow function and durability of the vertical pipe 2C group, and the vertical pipe 2C group. Since the outer shell of the header main pipe 2A is connected in a smooth shape, smooth natural convection of the airflow flowing around the outer periphery of the vertical pipe 2C group is ensured.

In addition, the vertical pipe 2C group that constitutes the heat generating surface has heat generation and cooling effects from the entire surface of the heat radiator through the simultaneous water flow from the upper and lower header main pipes 2A. (Slightly over 70%), and by the total action of radiant heat and natural convection heat with natural convection subordinate (slightly less than 30%), it exhibits gentle heating and cooling that is gentle to the human body, and there is no uncomfortable forced air flow. It is possible to provide a high-quality heating / cooling system that warms and cools the living room without any spots.
And since arrangement | positioning of a radiator is suitable for the suspension form via the upper header 1, arrangement | positioning to the partition wall space of a building is also possible, and the concealment arrangement | positioning heating / cooling system in the partition wall space is novel. Construction is also possible.

[Manufacture of heat dissipation panels (Figs. 2 and 3)]
The heat dissipating panel is formed by integrating two layers of the upper header main pipe 2A with different positions on the left and right to form a heat sink, and the small-diameter joint branch pipe 2B group is attached to the header main pipe 2A mounting hole. Two headers 1 which are fused and bonded to Ha and protruded in parallel from the side are arranged, and a group of elongated vertical pipes 2C are connected and integrated in a densely packed form between the upper and lower headers 1 as shown in FIG. Fig. 2B is an exploded perspective view of the header 1, Fig. 2B is a partial cross-sectional view of the header 1, and Fig. 2C is a vertical side view showing a connection state of the header 1 and the vertical pipe 2C. 3 is a partially enlarged plan view of the heat dissipation panel.

  As shown in FIG. 2 (A), the header 1 is fitted and integrated into a header main pipe 2A in which a mounting hole Ha group is drilled in parallel on one side surface, and a joint branch pipe 2B group is inserted into a side surface mounting hole Ha in the header main pipe 2A. In the upper header 1, as shown in FIG. 2A, a partition plate 2P is arranged in the main pipe 2A between the second joint branch pipe 2B from the left end and the right end, and both ends are closed. The lower header 1 is closed by a plate 2F, and the closing plate 2F is disposed at both ends of the main pipe 2A where the partition plate 2P does not exist.

That is, the upper and lower header main pipes 2A are prepared by injection molding of polypropylene, random, copolymer resin (PP-R resin), and the structure is as shown in FIG. A mounting hole Ha having a diameter of 7.8 mm is provided on one side surface of the main pipe 2A having a diameter of 5 mm, the inner diameter of the branch pipe 2B being the same as that of the joint branch pipe 2B. The center-to-center dimension PA of the mounting hole Ha in each block BP is 16 mm, the center-to-center dimension PB of the mounting hole Ha between the blocks BP is 18 mm, and the mounting hole Ha is formed from the outer surface of the main pipe 2A. A joint branch pipe 2B fitting step hole hb having a depth of 2 mm and a thickness of 1 mm is provided.
The upper header main pipe 2A has a partition plate 2P formed between the outermost mounting hole Ha and the second mounting hole Ha, and the lower header main pipe 2A has no partition plate 2P. Is used.

  Then, a pipe having a thickness of 1 mm and an outer diameter of 9.8 mm prepared by extrusion molding of PP-R resin is cut to prepare a joint branch pipe 2B. For example, a conventional technique (Japanese Patent Laid-Open No. 2007-247869) The joint branch pipe 2B is fitted into each mounting hole Ha of the header main pipe 2A, and the tip bf of the joint branch pipe 2B is fitted into the fitting step hole hb. Then, the joint branch pipe 2B having a protrusion length LB of 30 mm is attached to the header main pipe 2A so that the inner peripheral surface thereof is flush with the inner peripheral surface of the attachment hole Ha.

  Next, both ends of the vertical pipe 2C group prepared by cutting a pipe having an outer diameter dc of 13 mm and a wall thickness tc of 1.6 mm prepared by extrusion molding of PP-R resin into a predetermined size (standard: 1946 mm), As shown in FIG. 2C, the joint branch pipe 2B and the vertical pipe 2C are fitted on the outer periphery of the joint branch pipe 2B of the upper and lower headers so as to cover the protruding length (30 mm) of the joint branch pipe 2B. In the form of covering the outer periphery of the vertical pipe 2C with a heat fusion processing tool (not shown), the vertical pipe 2C and the joint branch pipe 2B are heat-sealed and joined to each other in the middle of the multi-layered portion of FIG. As shown in the figure, the vertical pipe 2C is integrated with a fusion part 2T in a form in which the fusion resin 2M appears on the entire circumference, and both ends of the upper and lower header main pipes 2A are closed with PP-R resin closing plates 2F, A heat radiating panel main body in which the vertical pipes 2C communicate with each other is obtained.

Next, if the supply port 2S is vertically projected between the partition plate 2P and the closing plate 2F of the upper header main pipe 2A from the heat dissipating panel body prepared for mass production with the same structure, the first shown in FIG. If the discharge port 2R is provided to project upward from the opposite end portion where the partition plate 2P of the upper header main pipe does not exist, the second heat dissipating panel 102 shown in FIG. 4 (D) is obtained.
Note that both the supply port 2S and the discharge port 2R may be formed by cutting the vertical pipe 2C material into a length of 50 mm.
The obtained first heat radiating panel 101 and the second heat radiating panel 102 both have an overall height h1 of 2000 mm, an exposed length h2 of the vertical pipe 2C group of 1946 mm, an overall width L1 of 362 mm, and each vertical pipe 2C is very small (3 mm). ), A set of three blocks BP having a pipe interval of a small distance (5 mm) and closely arranged in a repetitive form.

[Production of radiator He (Figs. 1 and 4)]
The heat radiator He of the present invention comprises a first heat radiating panel 101 and a second heat radiating panel 102 which are prepared by arranging a supply port 2S and a discharge port 2R on the opposite side in an all plastic resin heat radiating panel body having the same structure. The upper projecting pipe piece of the upper header main pipe 2A, that is, the supply port 2S and the discharge port 2R are overlapped in the front and rear form, and connected at the four corners, that is, at both ends of the upper header main pipe 2A and at both end positions of the lower header main pipe 2A. In this case, the left end portion of the upper header main pipe 2A of the first heat dissipating panel 101 and the space Sa defined by the closing plate 2F and the partition plate 2P of the second heat dissipating panel 102 are connected by the communication pipe 2D. The other three corners, that is, the end from which the pipe piece 2S (2R) protrudes and the both ends of the lower header main pipe 2A are simply integrated with a spacer pipe 2E having a gap between them. .

  When the front heat dissipation panel, that is, the first heat dissipation panel 101 and the rear heat dissipation panel, that is, the second heat dissipation panel 102 are joined and integrated, as shown in FIG. 1B and FIG. If the distance gs between the opposite header main pipes 2A is maintained at 4.5 mm, the distance gp between the vertical pipe 2C group surfaces of both panels becomes 18.5 mm, and the radiator He has a front and rear thickness W1 of 58.mm. The heat radiation panel 101, 102 multi-layer type is 5 mm, the width L1 is 362 mm, the total height h1 is 2000 mm, and the exposed length h2 of the vertical pipe 2C group is 1946 mm.

As shown in FIG. 4, when the obtained radiator He is supplied with hot water or cooling water from the supply port 2 </ b> S of the upper protruding pipe piece of the first radiator panel 101, the supply water flow f <b> 1 is divided into the partition plate 2 </ b> P and the closing plate. The downward flow f2 of the outermost vertical pipe 2C flows into the lower header main pipe 2A from the space Sa with 2F and flows into the lower header main pipe 2A, and becomes the simultaneous upward flow f4 of the vertical pipe 2C group from the lateral flow f3 of the lower header main pipe 2A. The full lateral flow f5 in the upper header main pipe 2A becomes a cross current f6 from the upper header main pipe 2A to the second heat radiating panel 102 via the communication pipe 2D. In the second heat radiating panel 102, the space Sa between the partition plate and the closing plate To the descending flow f7 in the vertical pipe 2C at the outermost end to become the lateral flow f8 in the lower header main pipe 2A, and the vertical pipe 2C group is lifted up from the lower header main pipe 2A all at once f9 to raise the upper head. Filling the cross flow f10 next in over main 2A, the effluent f11 from the outlet 2R.
And since the uppermost part, ie, the inside of the upper header main pipe 2A of the first heat radiating panel 101 and the second heat radiating panel 102, is prone to air accumulation in the water flow path, it is filled with the simultaneous upward flow from the vertical pipe 2C group. During operation of the radiator He, no air pool is generated in the radiator He.

  The radiator He has a thin front and rear thickness W1 (standard: 58.5 mm), a small width L1 (standard: 362 mm), and a vertically long (standard: 2000 mm). Each of the vertical pipes 2C group is a multi-layered type in which a single block BP, in which three pipes are densely packed with a minute gap gc of 3 mm, is repeatedly arranged in parallel with a small gap gc ′ of 5 mm, so that the inside of the block BP The gap gc 'between the blocks BP ensures air convection between the space between the front and rear heat dissipation panels and the outside of the heatsink He, while exhibiting an increase in heat dissipation due to high-density parallelism, and convective heat transfer along with radiant heat radiation Therefore, a heat radiator He having no heat dissipation spots and a large calorific value is guaranteed.

In addition, when the heatsink He obtained in the embodiment of the present application was subjected to a comparative heat generation test at the heatsink of the conventional example 3 (FIG. 7) and the Hokkaido Industrial Test Station, the heat generation amount increased by 23.5%. Results were obtained.
Therefore, the radiator He of the present invention can be arranged in a suspended form between the pillars of the partition wall of the building, for example, and if connected to the running water supply pipe S and the discharge pipe R of the ceiling pipe, It is possible to construct a new heating / cooling system with a large calorific value that does not cause air accumulation and does not interfere with the room space.
