Description

  The present invention relates to a heat exchanger.

  Some heat exchangers turn a fluid flowing inside the heat exchanger by providing a separator inside the tank. For example, Patent Document 1 discloses a heat exchanger in which a partition plate serving as a separator that divides the internal space of the header tank is provided inside the header tank. In the heat exchanger described in Patent Document 1, the separator is interposed between the tank header and the plate header when the tank head included in the header tank and the plate header are fitted. And it is assembled | attached so that the protrusion part of a separator may penetrate the through-hole of a tank header.

JP 2003-139483 A

  Conventionally, when assembling by placing the separator in the header tank, an assembly process is performed in which the separator tank is disposed so as to pass through a part of the outer peripheral wall of the header tank, and then a brazing process is performed in which it is heated and brazed. . The separator is configured such that a gap is not formed between the separator and the outer peripheral wall when the separator is disposed perpendicular to the outer peripheral wall. Therefore, if the separator is inclined, a gap is generated between the separator and the outer peripheral wall, and the gap may not be filled by brazing. When such a brazing defect occurs, the flow path through which the fluid originally flows is short-cut when the heat exchanger is operated, so that it must be handled as a defective product, resulting in a poor yield. Although the solution means of providing the separator penetration structure in the above-mentioned prior art over the entire circumference of the separator is also conceivable, since the header tank constituting the heat exchanger has a side surface to which the tube is connected, the penetration structure is arranged around the circumference. It cannot be installed across.

  This invention is made in view of such a subject, The objective is to provide the heat exchanger which suppresses that the separator which divides | segments the internal space of a header tank inclines in an assembly process and a brazing process. is there.

  In order to solve the above problems, a heat exchanger (100) according to the present invention includes a header tank (120, 120C) connected to a longitudinal end of a tube (111) for guiding a fluid, and an interior of the header tank. Separators (150, 150A, 150B) that divide the space, and the header tank has tank side abutting portions (121b, 121bA) that abut against the separator. It has a contact part (151, 151A, 151B). The tip of one of the tank side contact portion and the separator side contact portion is configured as a split portion (122bA, 153, 153B) having a cracked shape, and the other tip enters the tip split portion. Is formed.

  In the present invention, at the portion where the separator and the header tank abut, either one of the separator and the header tank is provided with a leading portion, and the other enters the leading portion. Since the separator can be configured so as not to deviate from the place where the leading portion is formed with respect to the header tank, the inclination of the separator can be suppressed without providing a through structure.

  In order to solve the above problems, a heat exchanger (100D) according to the present invention is provided between a plate header (120eD) and a plate header connected to an end portion in a longitudinal direction of a tube (111) for guiding a fluid. A header tank (120D) having a tank header (120aD) that forms an internal space, and a separator (150D) that divides the internal space of the header tank, and at least one of the plate header and the tank header includes a plate header and a tank A holding portion (125e) for holding the end portion of the other side of the header is provided.

  In the present invention, by providing the holding portion, the other can hold the end of the plate header or tank header, so even if the material forming the plate header or tank header is thinned, A predetermined shape can be maintained. Accordingly, the internal space formed between the plate header and the tank header can also be maintained in a predetermined shape, so that the separator can be held at a predetermined position and its inclination can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the heat exchanger which suppresses that the separator which divides | segments the internal space of a header tank inclines in an assembly process and a brazing process can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  First, the heat exchanger according to the present embodiment will be described with reference to FIGS. 1 and 2. The heat exchanger 100 according to the present embodiment includes a core part 110, an upper header tank 120, and a lower header tank 130. The upper header tank 120 corresponds to the “header tank” of the present invention. The core part 110 includes a plurality of tubes 111, a plurality of corrugated fins 112, and side plates 113. The plurality of tubes 111 and the plurality of corrugated fins 112 are alternately stacked. Side plates 113 are disposed on the outer sides of the outermost corrugated fins 112 in the stacking direction.

  The outer shape of the cross section of the tube 111 is flat. The tube 111 is formed by, for example, extrusion. A plurality of flow paths through which a fluid such as a refrigerant flows are formed inside the tube 111. As shown in FIGS. 1 and 2, the tubes 111 are provided in two internal spaces between the upper header tank 120 and the lower header tank 130, and are arranged in two rows in the flow direction of the blown air.

  The corrugated fin 112 is a roller molded product obtained by processing a thin strip material into a wave shape. A louver is formed on the surface of the corrugated fin 112 to increase the heat exchange efficiency. The louver is not shown in FIGS. 1 and 2.

  The side plate 113 constitutes a reinforcing member in the core portion 110, and is formed from a flat plate material by pressing. When viewed in the longitudinal direction of the side plate 113, the cross section of the side plate 113 exhibits a shape in which the central portion is recessed as a whole. On the bottom wall on the side where the side plate 113 abuts on the corrugated fin 112, a plurality of ribs having a wavy cross section for improving the strength are provided in the longitudinal direction.

  As shown in FIG. 2, the upper header tank 120 is divided into two in the longitudinal direction of the tube 111, and includes a tank header 120a and a plate header 120b. The tank header 120 a is provided on the side opposite to the tube 111. The plate header 120b is provided on the tube 111 side.

  Each of the tank header 120a and the plate header 120b has a semicircular or semi-rectangular cross-sectional shape when viewed in the longitudinal direction of the upper header tank 120, and is formed by pressing from a flat plate material. The tank header 120a and the plate header 120b are fitted to each other to form an upper header tank 120 as a cylindrical body in which two internal spaces are arranged in the flow direction of the blown air.

  Caps 140 are brazed to the openings 121 formed at both ends in the longitudinal direction of the upper header tank 120. The cap 140 closes the opening 121.

  As shown in FIG. 1, two separators 150 are brazed at a substantially central portion in the longitudinal direction of the upper header tank 120. The two separators 150 divide the two internal spaces of the upper header tank 120 in the longitudinal direction of the upper header tank 120 that is the left-right direction. That is, the separator 150 provided in the upper header tank 120 on the downstream side of the blown air flow divides the internal space of the upper header tank 120 into the first partial space 120s and the second partial space 120t. The separator 150 provided in the upper header tank 120 on the upstream side of the blown air flow divides the internal space of the upper header tank 120 into a third partial space 120u and a fourth partial space 120v.

  In the heat exchanger 100, in the region on the right side of the separator 150 of the upper header tank 120 when viewed in the flow direction of the blown air, the two internal spaces of the upper header tank 120 communicate with each other through a plurality of communication paths. . That is, the second partial space 120t and the fourth partial space 120v communicate with each other through a plurality of communication paths.

  The lower header tank 130 is similar to the upper header tank 120. Caps 140 are provided in openings 131 formed at both ends in the longitudinal direction of the lower header tank 130. This is as described for the configuration of the upper header tank 120. In the lower header tank 130, the separator 150 and the communication path described above are not provided.

  The end portions of the tubes 111 and the end portions of the side plates 113 are respectively inserted and brazed on the wall surfaces of the upper header tank 120 and the lower header tank 130 on the core portion 110 side. Thereby, the tube 111 communicates with the internal space of the upper header tank 120 and the lower header tank 130.

  As shown in FIG. 1, a block-like joint 160 is brazed to the left end of the upper header tank 120 when viewed in the flow direction of the blown air. The joint 160 has an inlet 161 through which a refrigerant as a fluid flows in and an outlet 162 through which the refrigerant flows out. The inflow port 161 communicates with the first partial space 120 s in the internal space of the upper header tank 120. In addition, the outlet 162 communicates with the third partial space 120 u in the internal space of the upper header tank 120.

  In the heat exchanger 100, the fluid flows from the inlet 161 into the first partial space 120 s of the upper header tank 120, and then flows by making a U-turn up and down through the tube 111 group on the downstream side of the blast air flow. It is guided to the partial space 120t. The fluid guided to the second partial space 120t is guided to the fourth partial space 120v through the communication path. The fluid guided to the fourth partial space 120v moves to the tube 111 group on the upstream side of the blown air flow, flows in a U-turn up and down, flows to the third partial space 120u, and then flows out from the outlet 162. To do.

  Next, the assembly structure of the separator and the upper header tank will be described with reference to FIGS.

  The outer shape of the separator 150 is formed so as to correspond to the inner shape of the upper header tank 120. As shown in FIG. 5, the separator 150 includes a first protrusion 152 that protrudes toward the tube 111, and a second protrusion 154 that protrudes away from the tube 111. The first protrusion 152 and the second protrusion 154 are provided at a substantially central portion in the flow direction of the blown air when the separator 150 is assembled to the upper header tank 120.

  The separator 150 is interposed and assembled between the tank header 120a and the plate header 120b when the tank header 120a and the plate header 120b are fitted. At this time, the 1st protrusion part 152 fits in the hole provided in the plate header 120b. Moreover, the 2nd protrusion part 154 fits in the hole provided in the tank header 120a, for example. Then, after the separator 150 is temporarily fixed to the upper header tank 120, the upper header tank 120 and the separator 150 are brazed to each other.

  Here, during the heating of the assembly process or the brazing process of the separator, the separator may be inclined with respect to the upper header tank, and an excessive clearance may be generated between the separator and the header tank. Then, brazing failure occurs, and fluid may leak during operation of the heat exchanger.

  On the other hand, in the heat exchanger 100 according to the present embodiment, as shown in FIG. 3, the plate header 120 b is fitted into the leading portion 153 of the separator 150 in the tank side contact portion 121 b. The separator 150 is in contact with the plate header 120b at the separator-side contact portion 151 provided at the end portion on the plate header 120b side. As shown in FIG. 3, the separator 150 has a front split portion 153 whose tip is cracked at the separator-side contact portion 151. The front split portion 153 is formed by splitting the side surface at the tip of the separator-side contact portion 151.

  On the other hand, the plate header 120b hits the separator 150 at a tank side contact portion 121b protruding toward the separator 150 side. As shown in FIG. 3, the plate header 120b is fitted into the leading portion 153 in the tank side contact portion 121b.

  Therefore, the upper header tank 120 and the separator 150 are fitted to each other during heating of the assembly process or brazing process of the separator 150. Therefore, the separator 150 can be prevented from moving with respect to the upper header tank 120. Specifically, it is possible to prevent the separator 150 from being inclined with respect to the upper header tank 120. Therefore, it can be suppressed that an excessive clearance is generated between the separator 150 and the upper header tank 120. Thereby, it is possible to suppress the occurrence of defective brazing and to prevent the fluid flowing through the upper header tank 120 from leaking.

  In addition, since the plate header 120b is fitted into the front split portion 153 in the tank-side contact portion 121b, the longitudinal direction of the upper header tank 120 even when the separator 150 moves slightly with respect to the upper header tank 120. When viewed, a part of the front split portion 153 overlaps with the tank side contact portion 121b. Therefore, it is possible to further suppress the occurrence of excessive clearance between the separator 150 and the upper header tank 120.

  As shown in FIG. 3, when viewed in the direction perpendicular to the longitudinal direction of the upper header tank 120, the separator 150 is divided into two forks at the separator-side contact portion 151 and extends linearly. That is, the front split portion 153 has a shape that is bifurcated and extends linearly. Therefore, the separator 150 contacts the plate header 120b with a wide area or a long distance. Therefore, brazing can be performed even if there is a slight shift between the separator 150 and the plate header 120b. Therefore, assembly management at the time of manufacturing the heat exchanger 100 can be simplified.

  Further, the tank side contact portion 121 b is provided on the plate header 120 b of the upper header tank 120. Therefore, when assembling the separator 150, the upper header tank 120 can be easily fitted into the leading portion 153 of the separator 150, and the productivity of the heat exchanger 100 can be improved.

  Furthermore, the tank side contact portion 121b of the plate header 120b protrudes toward the separator 150 side. Therefore, when the heat exchanger 100 according to the present embodiment is used as an evaporator of an air conditioner, it is possible to suppress the tank-side contact portion 121b from becoming a resistance to the flow of blown air.

  In the heat exchanger 100 according to the present embodiment, as illustrated in FIG. 4, the separator 150A may be fitted into the leading portion 122bA of the plate header 120bA at the separator-side contact portion 151A.

  That is, in the assembly of the separator 150A and the upper header tank 120 shown in FIG. 4, the plate header 120bA hits the separator 150A at the tank side contact portion 121bA provided at the end of the separator 150A. The plate header 120bA has a front split portion 122bA whose tip is broken at the tank side contact portion 121bA. The leading portion 122bA is formed by cutting and raising the tip of the tank side contact portion 121bA.

  On the other hand, the separator 150A is in contact with the plate header 120bA at the separator-side contact portion 151A provided at the end of the plate header 120bA. As shown in FIG. 4, the separator 150 </ b> A is fitted into the leading portion 122 b </ b> A at the separator-side contact portion 151 </ b> A.

  Therefore, the upper header tank 120 and the separator 150A are fitted to each other when the separator 150A is assembled or when the brazing process is heated. Therefore, it is possible to prevent the separator 150A from moving with respect to the upper header tank 120. Specifically, it is possible to prevent the separator 150 </ b> A from being inclined with respect to the upper header tank 120. Therefore, it can be suppressed that an excessive clearance is generated between the separator 150A and the upper header tank 120. Thereby, it is possible to suppress the occurrence of defective brazing and to prevent the fluid flowing through the upper header tank 120 from leaking. Further, the same effect as described above with reference to FIG. 3 can be obtained.

  As shown in FIG. 5, the front split portion 153 is provided in a part of the separator-side contact portion 151. In the separator 150, the leading portion 153 is provided in a part of the separator-side contact portion 151 and is provided on both sides of the first protrusion 152. On the other hand, as shown in FIG. 6, in the separator 150B, the leading portion 153B is provided over the entire separator-side contact portion 151B. According to the separator 150B, the pre-splitting portion 153B is provided over the entire separator-side contact portion 151B, so that the plate header 120b extends over the entire separator-side contact portion 151B in the tank-side contact portion 121b. It is fitted in the portion 153B. Thereby, it is possible to further suppress the separator 150B from moving with respect to the upper header tank 120, and it is possible to further suppress the fluid flowing through the upper header tank 120 from leaking.

  In addition, the upper header tank may be formed as a cylindrical body provided with one internal space in the flow direction of the blown air, as shown in FIG. The upper header tank 120C is divided into two in the longitudinal direction of the tube 111, and has a tank header 120aC and a plate header 120bC. The tank header 120aC is provided on the side opposite to the tube 111. The plate header 120bC is provided on the tube 111 side.

  Each of the tank header 120aC and the plate header 120bC has a semicircular or semi-rectangular cross-sectional shape when viewed in the longitudinal direction of the upper header tank 120C, and is formed by pressing from a flat plate material. The tank header 120aC and the plate header 120bC are fitted with each other to form an upper header tank 120C as a cylindrical body provided with one internal space in the flow direction of the blown air. In this case, the tubes 111 are provided in a row in the flow direction of the blown air. Thus, in the heat exchanger 100 according to the present embodiment, the number of rows of the tubes 111 is not particularly limited.

  As described above, the heat exchanger 100 according to the present embodiment includes the upper header tanks 120 and 120C connected to the longitudinal ends of the tubes 111 that guide the fluid, and the separator that divides the internal space of the upper header tanks 120 and 120C. 150, 150A, 150B. The upper header tank 120 has tank side contact portions 121b and 121bA that contact the separators 150, 150A, and 150B. The separators 150, 150 </ b> A, 150 </ b> B have separator-side contact portions 151, 151 </ b> A, 151 </ b> B that contact the upper header tank 120. The tips of the separator-side contact portions 151 and 151B are configured as split portions 153 and 153B having a broken shape, and the tip of the tank-side contact portion 121b is configured to enter. The tip of the tank side contact portion 121bA is configured as a split portion 122bA having a cracked shape, and the tip of the separator side contact portion 151A is configured to enter. Therefore, the tip of one of the tank side contact portion and the separator side contact portion is configured as a split portion having a cracked shape, and the other tip is formed so as to enter the split portion. .

  In the present embodiment, at the portion where the separators 150, 150A, 150B and the upper header tank 120 abut, either the separator or the header tank is provided with a leading portion, and the other enters the leading portion. ing. Since the separators 150, 150A, and 150B can be configured so as not to deviate from the location where the leading portion is formed with respect to the upper header tank 120, the inclination of the separators 150, 150A, and 150B can be provided without providing a through structure. Can be suppressed.

  As described above, in the present embodiment, the upper header tank 120 includes the plate headers 120b and 120bA to which the tube 111 is connected, and the tank header 120a that forms an internal space between the plate headers 120b and 120bA. The tank side contact portions 121b and 121bA are provided on the plate headers 120b and 120bA.

  Since the tank side contact portions 121b and 121bA are provided in the plate headers 120b and 120bA to which the tube 111 is connected, the separators 150, 150A and 150B are held without providing through holes in the plate headers 120b and 120bA. Can do. Even if the plate headers 120b and 120bC constituting the upper header tank 120 are used for the lower header tank 130, since the through holes are not formed, they can be discharged without causing dew condensation.

  As described above, in the present embodiment, the separators 150 and 150B are configured as plate-like members, and the front split portions 153 and 153B extend along the direction in which the end surfaces of the end faces of the separators 150 and 150B that are plate-like members extend. The tank side abutting portion 121b is formed so as to be divided and formed in a convex shape on the plate header 120b.

  As described above, in the present embodiment, the leading portion 122bA is provided on the tank-side contact portion 121bA that is convexly formed on the plate header 120bA, and sandwiches the separator 150A configured as a plate-like member.

  Subsequently, a heat exchanger according to another embodiment of the present invention will be described with reference to FIGS. FIG. 8 corresponds to a cross-sectional view taken along section line II-II shown in FIG. A heat exchanger 100D shown in FIG. 8 includes a core part 110, an upper header tank 120D, and a lower header tank 130. The core part 110 and the lower header tank 130 are as described with reference to FIG. 1 and FIG.

  The upper header tank 120D is divided into two in the longitudinal direction of the tube 111, and includes a tank header 120aD and a plate header 120eD. The tank header 120aD is provided on the side opposite to the tube 111. The plate header 120eD is provided on the tube 111 side.

  Each of the tank header 120aD and the plate header 120eD has a semicircular or semirectangular cross-sectional shape when viewed in the longitudinal direction of the upper header tank 120D, and is formed by pressing from a flat plate material. The tank header 120aD and the plate header 120eD are fitted together to form an upper header tank 120D as a cylindrical body in which two internal spaces are arranged in the flow direction of the blown air.

  As shown in FIGS. 8 and 9, the plate header 120eD has a pair of holding portions 125e provided on the inner wall 127e. As shown in FIG. 11, the pair of holding portions 125e is formed by cutting and raising the inner wall 127e of the plate header 120eD. As shown in FIGS. 8 and 9, the holding portion 125e holds the end portion of the tank header 120aD inside the plate header 120eD, and the outside of the plate header 120eD, that is, the arrows A1 and A2 shown in FIG. Suppress the spread toward the direction of.

  As shown in FIG. 10, in the heat exchanger 100D according to the present embodiment, the two holding portions 125e are arranged side by side in the longitudinal direction of the upper header tank 120D. A separator 150D is sandwiched between the two holding portions 125e. The separator 150D is formed so as to correspond to the shape inside the upper header tank 120D, and is in contact with the holding portion 125e. The other structure of the heat exchanger 100D is similar to the structure of the heat exchanger 100 described above with reference to FIGS.

  According to the heat exchanger 100D according to the present embodiment, when the tank header 120aD is fixed to the plate header 120eD, the end of the tank header 120aD is held by the holding portion 125e provided inside the plate header 120eD. The holding part 125e suppresses the plate header 120eD from spreading outward. Therefore, it is possible to prevent the plate header 120eD from expanding outward and the fluid flowing through the upper header tank 120D from leaking from the expanded portion.

  Further, since the holding portion 125e suppresses the plate header 120eD from spreading outward, it is possible to suppress an excessive clearance from being generated between the separator 150D and the plate header 120eD. Thereby, it is possible to suppress the occurrence of brazing failure and to prevent the fluid flowing through the upper header tank 120D from leaking.

  Separator 150D is sandwiched between two holding portions 125e. The separator 150D is in contact with the holding portion 125e. Therefore, the movement of the separator 150D with respect to the upper header tank 120D is suppressed. For example, it is possible to suppress the separator 150D from being inclined with respect to the upper header tank 120D. Therefore, it can be suppressed that an excessive clearance is generated between the separator 150D and the plate header 120eD.

  Note that the two holding portions 125e are not necessarily provided. For example, one holding part 125e may be provided. In the heat exchanger 100D according to the present embodiment, the number of the holding portions 125e is not particularly limited. Even when one holding portion 125e is provided, when the separator 150D is in contact with the holding portion 125e, the movement of the separator 150D with respect to the upper header tank 120D is suppressed.

  The heat exchanger 100D according to the present embodiment includes an upper header tank 120D that is provided at an end portion in the longitudinal direction of the tube 111 that guides fluid and is connected to the tube 111. The upper header tank 120D includes a plate header 120eD in which the tube 111 is inserted and fixed, and a tank header 120aD provided on the opposite side of the tube 111 from the plate header 120eD and fixed to the plate header 120eD. The plate header 120eD has a holding portion 125e that holds the end of the tank header 120aD on the plate header 120eD.

  When the tank header 120aD is fixed to the plate header 120eD, the end of the tank header 120aD is held by a holding portion 125e provided inside the plate header 120eD. The holding part 125e suppresses the plate header 120eD from spreading outward. Therefore, it is possible to prevent the plate header 120eD from expanding outward and the fluid flowing through the upper header tank 120D from leaking from the expanded portion.

  Since the holding portion 125e is provided on the inner side surface of the plate header 120eD, the inner side surface of the plate header 120eD can be attracted and held to the tank header 120aD. In the present embodiment, the holding portion 125e is provided on the plate header 120eD, but may be provided on the tank header 120aD.
