Definitions

  • the present invention relates to a heat exchanger unit and a method of manufacturing the same.
  • a stacked-type heat exchanger unit 9 shown in FIG. 20 is known.
  • electronic components 4 are arranged between the tubes 92 to be cooled by a heat medium flowing in the tubes 92 through side surfaces thereof.
  • This kind of heat exchanger unit is for example disclosed in Japanese Patent Publication No. 2001-320005.
  • ends of the tubes 92 are connected to a first header 94 and a second header 95 . Because the first header 94 and the second header 95 are provided as individual parts, the number of parts increases. As such, manufacturing costs are likely to increase.
  • the tubes 92 are fixed to the first header 94 and the second header 95 . Therefore, it is difficult to change spaces between adjacent tubes 92 . With this, it is difficult to insert the electronic components 4 between the tubes 92 so that both of the side surfaces of the electronic components 4 properly contact the tubes 92 .
  • FIG. 21 Another stacked-type heat exchanger unit is known, as shown in FIG. 21 .
  • tubes 92 are arranged such that electronic components 4 are interposed between the adjacent tubes 92 .
  • communication members 93 are disposed between the tubes 92 so that the tubes 92 communicate with each other through the communication members 93 .
  • This kind of heat exchanger unit is for example disclosed in Japanese Patent Publication No. 2002-26215.
  • the tubes 92 and the communication members 93 are provided as individual parts. It is necessary to connect the communication members 93 to the tubes 92 . As such, manufacturing costs are likely to increase. Further, it is difficult to improve productivity.
  • a heat exchanger unit has a plurality of tubes each having a flat body section and at least one of an inner pipe section and an outer pipe section extending from the body section in a direction perpendicular to an axis of the body section and defining an opening at an end.
  • the body section defines a passage through which a heat medium flows.
  • Each of the inner pipe section and the outer pipe section has a first portion and a second portion adjacent to the first portion.
  • the first portion and the second portion of the inner pipe section have an outer diameter smaller than an inner diameter of the first portion and the second portion of the outer pipe section.
  • the tubes are stacked such that the body sections are spaced from each other for performing heat exchange between the heat medium and an object existing between the adjacent body sections, and the inner pipe section is received in the outer pipe section, to thereby form a header part for permitting communication between the adjacent body sections.
  • the inner pipe section is received in the outer pipe section such that the first portion of the inner pipe section overlaps the first portion of the outer pipe section, and the second portions of the inner pipe section and the outer pipe section are located on opposite sides of the overlapped first portions in an axial direction of the inner pipe section and the outer pipe section.
  • the passages of the adjacent tubes are communicated with each other through the inner pipe sections and the outer pipe sections, which are coupled to each other. As such, it is not necessary to use an additional member for coupling the adjacent tubes. Thus, the number of parts reduces and manufacturability improves.
  • the inner pipe section and the outer pipe section are coupled by joining side walls thereof.
  • the header part has an inner diameter substantially equal to the inner diameter of the inner and outer pipe sections. Therefore, flow resistance in the header part is reduced, and pressure loss in the header part is suppressed. Accordingly, the heat medium can be distributed substantially equally into the plural tubes. As a result, heat exchange is properly performed.
  • the inner pipe section has the second portion that has the outer diameter smaller than the inner diameter of the first portion of the outer pipe section.
  • the outer pipe section has the second portion that has the inner diameter larger than the outer diameter of the first portion of the inner pipe section. Therefore, the inner pipe section and the outer pipe section do not have portions that contact and push each other in the axial direction of the inner pipe section and the outer pipe section while the inner pipe section is inserted in the outer pipe section.
  • a heat exchanger unit has a plurality of tubes each having a flat body section and at least one of an inner pipe section and an outer pipe section extending from the body section in a direction perpendicular to an axis of the body section and defining an opening at an end.
  • the body section defines a passage through which a heat medium flows.
  • the outer pipe section has a flange portion at the end. An end of the flange has a diameter larger than an inner diameter of a remaining portion of the outer pipe section.
  • the tubes are stacked such that the inner pipe section is inserted in the outer pipe section in a condition that a brazing material is disposed between the flange of the outer pipe section and the inner pipe section.
  • a brazing material is melted and then hardened, an outer side wall of the inner pipe section and an inner side wall of the outer pipe section are brazed to each other.
  • the brazing material is easily held by the flange while the inner pipe section is inserted in the outer pipe section. Furthermore, the brazing material can easily flow between the outer side wall of the inner pipe section and the inner side wall of the outer pipe section. Accordingly, the adjacent tubes are easily and properly joined to each other.

  • the brazed projecting pipe sections 22 have rigidity in the axial direction, that is, in the stacking direction so that the pipe sections 22 are not buckled even if pressure having the magnitude that can deform the diaphragm portions 23 is applied.
  • the spacing jig 6 has a thickness slightly larger than a thickness of the electronic component 4 . Therefore, there are clearances between the tubes 2 and the electronic component 4 at the stage shown in FIG. 10C .
  • the heat exchanger 1 is pressed in the stacking direction.
  • the diaphragm portions 23 receive pressure through the projecting pipe sections 22 . Therefore, the diaphragm portions 23 are deformed inside of the tubes 2 , that is, in a direction parallel to the axis of the header parts 11 , 12 , as shown in FIG. 10D .
  • the electronic components 4 are constructed as semiconductor modules having semiconductor elements such as IGBT (Insulated Gate Bipolar Transistor) and diodes.
  • the semiconductor modules construct part of an inverter for an automobile.
  • As the heat medium 5 water containing ethylene glycol antifreeze liquid is used, for example.
  • the electronic components 4 can be held in directly contact with the tubes 2 .
  • insulation plates such as ceramic plates or heat conductive grease can be interposed between the electronic components 4 and the tubes 2 .
  • the projecting pipe sections 22 are coupled by joining the side walls, as shown in FIG. 2 . Therefore, the passage areas of the first header part 11 and the second header part 12 are ensured by the inner diameter of the projecting pipe sections 22 . Namely, the passage diameter of the first header part 11 and the second header part 12 is substantially equal to the inner diameter of the projecting pipe sections 22 . As such, a flow resistance in the first header 11 and the second header 12 is reduced, and therefore pressure loss in the first header 11 and the second header 12 is reduced. With this, the heat medium 5 is substantially equally distributed into the plural tubes 2 . As a result, the plural electronic components 4 are equally cooled.
  • the outer diameter D 1 of the overlapping wall portion 224 a and the adjacent wall portion 225 b of the inner pipe section 222 is smaller than the inner diameter D 2 of the overlapping wall portion 224 b and the adjacent wall portion 225 b of the outer pipe section 223 . Therefore, it is less likely that the inner pipe section 222 and the outer pipe section 223 will push each other. As such, the inner pipe section 222 and the outer pipe section 223 do not receive load in the axial direction of the inner pipe section 222 and the outer pipe section 223 .
  • the electronic components 4 are placed in the tubes 2 , as shown in FIG. 10C . Then, the stack of tubes 2 are compressed in the stacking direction. As such, the tubes 2 contact the electronic components 4 , as shown in FIG. 10D . If the tubes 2 are partly deformed before the electronic components 4 are placed, it is difficult to place the electronic components 4 between the tubes 2 . Therefore, it is significant to reduce the deformation of the tubes 2 during the stacking.
  • the outer pipe section 223 has the flange 226 at the end. Therefore, it is easy to arrange the wire brazing material 15 between the flange 226 and the inner pipe section 222 , which is opposed to the flange 226 . Further, the melted brazing material 15 easily flows in the space defined between the inner pipe section 222 and the outer pipe section 223 along the flange 226 . Accordingly, the adjacent tubes 2 are easily and properly joined. Thus, the heat exchanger 1 is easily manufactured.
  • the outer diameter Dt of the extending wall portion 227 a is larger than the outer diameter Dk of the overlapping wall portion 224 a .
  • the wire brazing material 15 can be pressed against the flange 226 by the extending wall portion 227 a of the inner pipe section 222 . Therefore, it is less likely that the wire brazing material 15 will be displaced. As such, the inner pipe section 222 and the outer pipe section 223 are properly brazed.
  • each of intermediate tubes 2 is constructed of the pair of outer plates 27 , the middle plate 28 and the inner fins 29 .
  • the intermediate tubes 2 are the tubes 2 that are located in a middle section of the stack of the tubes 2 . That is, the intermediate tubes 2 are the tubes 2 other than the end tubes 2 .
  • the outer plates 27 , the middle plate 28 and the inner fins 29 are separately formed into the predetermined shapes such as by pressing. Then, the outer plates 27 , the middle plate 28 and the inner fins 29 are joined to each other.
  • the tubes 2 having drawn cup structure can be produced. Accordingly, the tubes 2 are easily manufactured.
  • the end tubes 2 can be formed of the outer plates 27 , the middle plate 28 and the inner fins 29 .
  • the inner fins 29 are formed at desired positions. Because the inner fins 29 are not arranged at positions corresponding to the first header 11 and the second header 12 , it is easy to process the first header 11 and the second header 12 .
  • each of the tubes 2 has double layered passages 21 in the stacking direction. Therefore, it is less likely that heat will be transferred between the adjacent electronic components 4 arranged on opposite sides of the tube 2 . As such, even if the temperature of the electronic component 4 arranged on one side of the tube 2 is rapidly increased, the electronic component 4 arranged on the opposite side of the tube 2 will not be affected.
  • the inner diameter of the extending wall portion 227 a and the inner diameter of the extending wall portion 227 b that is opposite to the extending wall portion 227 a in the same tube 2 have the equal inner diameter. Therefore, the diaphragm portion 23 on one side of the tube 2 and the diaphragm portion 23 on the opposite side of the same tube 2 have the same diameter. Accordingly, the amount of deformation is equal in the pair of diaphragm portions 23 in the same tube 2 .
  • the outer diameter Dp of the flange 226 is larger than the outer diameter Dr of the wire brazing material 15 , as shown in FIG. 3 . Therefore, the wire brazing material 15 is easily and properly held between the inner pipe section 222 and the outer pipe section 223 , at the flange 226 . Also, when the brazing material 15 melts, the melted brazing material 15 easily flows between the inner pipe section 222 and the outer pipe section 223 without overflowing from the flange 226 .
  • the heat exchanger unit 10 can be easily manufactured in the above manner. Further, it is less likely that the tubes 2 will be deformed during the stacking. Also, the manufacturing cost reduces.

  • the core of the inner fin 29 is made of aluminum containing zinc.
  • each inner fin 29 is made of aluminum containing zinc. Therefore, the core of the inner fins 29 has an electrical potential (corrosion potential) lower than that of the core 271 of the outer plate 27 . Because the inner fin 29 is more likely to be corroded than the outer plate 27 , the corrosion of the outer plate 27 is reduced.

  • the sacrificial anode material 273 since the inner surface of the core 271 of the outer plate 27 is covered with the sacrificial anode material 273 , the sacrificial anode material 273 is selectively corroded. Therefore, it is less likely that the core 271 will corrode. Because the corrosion of the outer plate 27 in its thickness direction is restricted, it is less likely that the tubes 2 will have holes due to corrosion.
  • the heat exchanger unit 10 of the third example embodiment provides advantageous effect similar to those of the first and second example embodiments.
  • the tubes 2 are easily assembled. Since the brazing material 272 is disposed on the inner surfaces of the outer plates 27 , it is easy to join the outer plates 27 each other and with the inner fins 29 . Further, the brazing material 272 is also disposed on the inner surface of the projecting pipe section 22 , it is not necessary to use the wire brazing material 15 as the first to third example embodiments. As such, the inner pipe section 222 and the outer pipe section 223 are easily and properly brazed through the brazing material 272 .
  • the core 281 of the middle plate 28 is made of aluminum containing zinc, the core 281 has a potential (corrosion potential) lower than that of the core 271 of the outer plate 27 .
