Description

  The present invention relates to a compact heat exchange module or the like having high heat dissipation efficiency.

  For example, in order to cool a heat generating part such as an automobile motor, a heat exchange module that radiates heat of the heat generating part to the outside air or the like is used. In this case, the heat generating part and the heat radiating part may be arranged at positions separated by the layout of the device. In this case, heat transport is performed from the heat generating portion to the heat radiating portion by, for example, a heat pipe.

  In addition, heat transport and heat dissipation may not catch up with instantaneous or pulsed heat generation. Therefore, for such heat generation, there is a method of arranging a heat storage unit and storing heat generated in the heat generation unit in the heat storage unit.

  As such a heat exchange module, for example, a heat receiving unit thermally connected to the heat generating element and a heat receiving block including a heat storage unit for temporarily storing heat of the heat generating element are provided. There is a cooling device connected by a heat pipe (Patent Document 1).

JP 2010-267912 A

  However, in a cooling device like patent document 1, since the heat storage part and the heat dissipation part are separated, the heat dissipation efficiency of the heat stored in the heat storage part is poor. For this reason, in order to ensure the amount of heat radiation, a large heat radiation fin is required. Moreover, since the heat transfer area between the heat transport unit and the heat storage unit is small, heat cannot be efficiently transferred to the heat storage unit.

  On the other hand, there is a method of using a heat storage member in the heat storage section. However, when a container holding such a heat storage member is used as the heat storage unit, a thermal resistance between the container and the heating element or the heat transport unit is generated. For this reason, it is not possible to efficiently transfer heat to the heat storage unit.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a heat exchange module and the like that have high heat dissipation efficiency and are compact.

  In order to achieve the above-described object, the first invention includes a heat transport unit that comes into contact with the heat generating unit, a heat storage unit capable of storing heat from the heat transport unit, and a heat dissipation unit provided in the heat transport unit, And the heat transport unit and the heat storage unit are integrally formed, and the heat storage unit houses a heat storage member therein.

  The heat storage unit may be provided with a plurality of fins, and the heat storage member may be filled between the fins.

  It is desirable that the opening direction of the fins substantially coincides with the heat transport direction of the heat transport portion.

  It is desirable that a heat pipe is embedded in the heat transport part.

  The heat storage part has at least a heat generation part side heat storage part located on the heat generation part side and a heat radiation part side heat storage part located on the heat dissipation part side, and the heat storage member filled in the heat generation part side heat storage part The melting point of the heat storage member may be higher than the melting point of the heat storage member filled in the heat radiating unit side heat storage unit.

  The heat storage unit includes at least a first heat storage unit in contact with the heat transport unit, and a second heat storage unit stacked on the first heat storage unit, and a heat storage member filled in the first heat storage unit. You may make melting | fusing point higher than melting | fusing point of the thermal storage member with which the said 2nd thermal storage part is filled.

  According to the first invention, since the heat storage part and the heat transport part that can accommodate the heat storage member are integrally formed, there is no need to use a separate thermal interface or the like between the heat storage part and the heat transport part. For this reason, the thermal resistance between a heat storage part and a heat transport part can be made small. Moreover, since the heat storage part and the heat transport part are integrated, the heat during movement of the heat transport part can also be efficiently stored in the heat storage part. For this reason, it is excellent in a heat dissipation characteristic and can make a thermal radiation part compact.

  Moreover, a heat | fever can be efficiently stored in a thermal storage part by providing a fin inside a thermal storage part and filling a thermal storage member between fins. At this time, by making the opening direction of the fins substantially coincide with the heat transport direction, the heat exchange module main body including the fins can be integrally manufactured in the heat transport direction by extrusion or drawing. Furthermore, heat can be efficiently transported by embedding a heat pipe in the heat transport section.

  Further, the heat storage part is divided into a heat generation part side heat storage part located on the heat generation part side and a heat radiation part side heat storage part located on the heat dissipation part side, and the melting point of the heat storage member filled in the heat generation part side heat storage part is By making it higher than the melting point of the heat storage member filled in the heat radiating part side heat storage part, it is possible to suppress the delay of heat dissipation by suppressing the heat storage on the side close to the heat generating part, and heat on the heat radiating part side. Since heat can be stored from the transport section to the heat dissipation section side heat storage section, heat can be efficiently transferred to the heat dissipation section.

  Moreover, the 1st heat storage part which contacts a heat transport part and the 2nd heat storage part laminated | stacked on a 1st heat storage part are provided, and melting | fusing point of the heat storage member with which a 1st heat storage part is filled is filled into a 2nd heat storage part By making the temperature higher than the melting point of the heat storage member, the heat storage efficiency of the heat storage unit can be secured, and in particular, the heat at the initial stage of heat generation can be efficiently transported to the heat dissipation unit.

  A second invention includes a heat exchange module and a motor coil, and the heat exchange module is a heat transport part that contacts the motor coil that is a heat generating part, and heat storage that can store heat from the heat transport part. And a heat dissipating part provided in the heat transport part, wherein the heat transport part and the heat storage part are integrally formed, and the heat storage part includes a heat storage member therein, and the motor coil The heat transport part is provided on the outer periphery, the heat storage part is provided on the outer periphery of the heat transport part, a heat pipe is embedded in the heat transport part, and the heat pipe protrudes from the motor coil. The motor structure is joined to the heat radiating portion.

  By doing in this way, the heat from a motor coil can be efficiently conveyed to a thermal radiation part.

  According to a third aspect of the present invention, a main body including a heat transporting portion that comes into contact with the heat generating portion and a heat storage portion capable of storing heat from the heat transporting portion is integrally formed by extrusion processing or drawing processing, and the heat storage portion In addition, the heat storage module is filled with a heat storage member, and a heat radiating part is joined to the heat transport part.

  According to the third aspect of the invention, the heat storage part that can accommodate the heat storage member and the heat transport part can be easily and integrally manufactured.

  A fourth invention uses a plurality of heat exchange modules according to the first invention, and disposes the heat dissipating part in an air flow path for heating a vehicle interior, so that the heat of the heating element is transferred to the air in the air flow path. A heating system that dissipates heat, wherein a plurality of the heat exchange modules are provided side by side from the upstream side to the downstream side of the air flowing through the air flow path, and the plurality of heat exchange modules are in contact with the heating elements, respectively, The heating system is characterized in that a plurality of the heat exchange modules are provided so as to increase the melting point of the heat storage member filled in the heat storage section of each of the heat exchange modules as going from the side to the downstream side. .

  According to the fourth aspect of the invention, for example, the heating element that is weak against heat is arranged on the upstream side of the cooling air, and the melting point of the heat storage member is lowered, so that overheating of the heating element can be suppressed. In addition, the heat-resistant heating element is arranged on the downstream side of the cooling air, and by increasing the melting point of the heat storage member, if the temperature of the heating element does not exceed a predetermined value, heat is not stored in the heat storage section, and it is efficient. The heat can be moved to the heat radiating part.

  According to the present invention, it is possible to provide a compact heat exchange module or the like with high heat dissipation efficiency.

Schematic which shows the heating system 50. FIG.

  Hereinafter, the heat exchange module 1 concerning embodiment of this invention is demonstrated. Fig.1 (a) is a side view which shows the heat exchange module 1, and FIG.1 (b) is the sectional view on the AA line of Fig.1 (a). The heat exchange module 1 is mainly composed of a main body 5 having a heat transport section 7 and a heat storage section 9, a heat radiating section 11 and the like.

  In the main body 5, the heat transport unit 7 and the heat storage unit 9 are integrally formed. The heat generating part 3 is in contact with one end of the heat transport part 7. Further, in the vicinity of the other end of the heat transporting part 7, a heat radiating part 11 composed of a plurality of fins is provided. That is, the heat transport unit 7 transports the heat of the heat generating unit 3 to the heat radiating unit 11.

  A heat pipe 13 is embedded in the heat transport section 7 along the heat transport direction. In addition, if the heat transport part 7 has sufficient heat transport capability, the heat pipe 13 is not necessarily required. In addition, the heat pipe 13 may not be completely embedded in the heat transport unit 7, and a part of the heat pipe 13 may be exposed on the surface of the heat transport unit 7.

  A heat storage unit 9 is integrally provided below the heat transport unit 7 (on the side opposite to the contact side with the heat generating unit 3). The heat storage unit 9 is filled with a heat storage member 15. That is, the heat storage unit 9 has a space that can accommodate the heat storage member 15. Both ends of the main body 5 are closed so that the heat storage member 15 does not leak.

  The heat storage member 15 only needs to be able to temporarily store heat. For example, a material capable of storing a large latent heat at the time of phase change, such as paraffin or “Passermo” (trade name) manufactured by Kanto Shoji Co., Ltd., can be used. .

  The heat storage unit 9 functions as follows. For example, when the heat generating unit 3 generates heat with a pulsed heat generation amount or generates a large amount of heat instantaneously, but the average heat generation amount is small, if the heat storage unit 9 is not provided, the large heat generation amount is It is necessary to dissipate heat at the timing. For this reason, a large heat radiating portion (for example, a large heat radiating fin) is required. On the other hand, the heat storage unit 9 functions when the temperature reaches a predetermined temperature or higher, and can temporarily store heat. Therefore, at the time of rapid heat generation, a part of the heat is stored, and after the heat generation is stabilized, the stored heat can be gradually released. For this reason, it is not necessary to enlarge the heat radiation part 11 excessively.

  The heat exchange module 1 can be manufactured as follows. First, the material of the main body 5 can be manufactured by, for example, extrusion or drawing. By doing in this way, the heat transport part 7 and the heat storage part 9 can be easily manufactured integrally. In this case, for example, holes and grooves for the heat pipe 13 can be easily formed in the heat transport direction. After the material of the main body 5 is cut to a predetermined length, the heat transport portion 7 is formed by soldering the heat pipe 13 to the hole or groove. Moreover, the heat storage part 9 is formed by filling the space of the heat storage part 9 with the heat storage member 15 and closing both ends. The heat radiating portion 11 is formed by joining the heat radiating fins to the upper surface of the main body 5 with solder or the like.

  According to the present embodiment, a part of the heat can be stored in response to the pulsed or instantaneous heat generation, so that it is not necessary to excessively increase the size of the heat radiating part 11. The heat storage unit 9 is formed integrally with the heat transport unit 7. For this reason, it is not necessary to use another thermal interface material etc. between the heat storage part 9 and the heat transport part 7, and thermal resistance can be made small.

  In addition, the heat storage unit 9 is provided along the heat transport unit 7 in a range from the contact portion between the heat transport unit 7 and the heat generating unit 3 to the heat radiation unit 11. For this reason, when a part of heat transport part 7 becomes high temperature, the heat storage part 9 functions in that part. Therefore, heat exchange with the heat storage part 9 is possible in each part of the heat transport part 7.

  Moreover, since the main body 5 is formed with a constant cross section in the heat transport direction by extrusion processing or drawing processing, it is easy to form the installation portion of the heat pipe 13 and the storage portion of the heat storage member 15.

  Next, a second embodiment will be described. 2A and 2B are views showing the heat exchange module 10 according to the second embodiment, where FIG. 2A is a side view, and FIG. 2B is a cross-sectional view taken along the line BB in FIG. 2A. is there. In the following description, the same components as those of the heat exchange module 1 are denoted by the same reference numerals as those in FIG.

  The heat exchange module 10 has substantially the same configuration as the heat exchange module 1, but the structure of the heat storage unit 9 is different. The heat storage unit 9 of the heat exchange module 10 is provided with fins 17. The heat storage member 15 is filled between the fins 17. Note that the fin 17 may have a corrugated fin shape as shown in the figure, or may have another shape. The fins 17 may be formed integrally with the main body 5 or may be joined after being formed separately. In addition, by forming the fins 17 in a direction that opens in the heat transport direction (left and right direction in FIG. 2A), the fins 17 can be processed integrally when the body 5 is extruded or drawn. it can.

  According to the second embodiment, an effect similar to that of the first embodiment can be obtained. In addition, by providing the heat storage unit 9 with the fins 17, heat exchange between the heat storage unit 9 and the heat transport unit 7 is promoted. Moreover, the main body 5 and the fin 17 can be manufactured integrally by forming the fin 17 in a direction opening in the heat transport direction.

  Next, a third embodiment will be described. FIGS. 3A and 3B are diagrams showing a heat exchange module 20 according to the third embodiment, in which FIG. 3A is a side view, and FIG. 3B is a cross-sectional view taken along the line C-C in FIG. is there. The heat exchange module 20 has substantially the same configuration as the heat exchange module 10, but the structure of the heat storage unit 9 is different.

  In the heat exchange module 20, the heat storage unit is divided into heat storage units 9a and 9b. In addition, the fin 17 in the thermal storage part 9a, 9b is provided as needed. The heat storage part 9a is provided in the contact part side with the heat generating part 3 with respect to the heat transport direction. Moreover, the heat storage part 9b is provided in the thermal radiation part 11 side. That is, the heat storage units 9a and 9b are provided in the heat transport direction so as to be in contact with the heat transport unit 7, respectively.

  The heat storage units 9a and 9b are different in heat storage members filled therein. Here, the melting point of the heat storage member filled in the heat storage unit 9a is higher than the melting point of the heat storage member filled in the heat storage unit 9b. That is, the phase change from an individual to a liquid is not performed unless the heat storage unit 9a rises to a higher temperature than the heat storage unit 9b. Therefore, heat storage unit 9a does not store heat unless heat generating unit 3 side of heat transport unit 7 rises to a certain temperature or higher. By doing so, the heat generated from the heat generating part 3 can be efficiently transported to the heat radiating part 11 side and radiated without storing the heat generated from the heat generating part 3 until the vicinity of the heat generating part 3 reaches a predetermined temperature.

  On the other hand, on the heat radiating part 11 side of the heat transport part 7, heat storage is started from a lower temperature. By doing in this way, when the heat dissipation amount by the heat radiating part 11 is insufficient, heat storage is started immediately and the temperature gradient of the heat transport part 7 can be maintained. Therefore, the heat of the heat generating part 3 side can be efficiently transported to the heat radiating part 11 side. In addition, it is desirable to provide a partition between the heat storage units 9a and 9b so that the respective heat storage members are not mixed. As a partition, you may insert between fins from an edge part, and you may insert a notch into a partition part from the outside and may insert a partition member.

  According to the third embodiment, an effect similar to that of the second embodiment can be obtained. Moreover, by dividing into heat storage parts 9a and 9b and changing the heat storage start temperature between the upstream side and the downstream side of heat, heat can be efficiently transported to the heat radiating part.

  Next, a fourth embodiment will be described. FIG. 4 is a view showing a heat exchange module 30 according to the fourth embodiment, FIG. 4 (a) is a side view, and FIG. 4 (b) is a sectional view taken along the line DD in FIG. 4 (a). is there. The heat exchange module 30 has substantially the same configuration as the heat exchange module 10, but the structure of the heat storage unit 9 is different.

  In the heat exchange module 30, the heat storage units 9c and 9d are stacked. The heat storage unit 9 c is provided on the lower surface of the heat transport unit 7 so as to be in contact with the heat transport unit 7. The heat storage unit 9d is stacked on the lower surface of the heat storage unit 9c. Both the heat storage units 9c and 9d are provided over the entire length of the heat transport unit 7.

  The heat storage parts 9c and 9d are different in the heat storage member filled therein. Here, the melting point of the heat storage member filled in the heat storage unit 9c is higher than the melting point of the heat storage member filled in the heat storage unit 9d. That is, the phase change from an individual to a liquid is not performed unless the heat storage unit 9c rises to a higher temperature than the heat storage unit 9d. Therefore, the heat storage unit 9c does not store heat unless the temperature of the heat transport unit 7 rises to a certain level. By doing in this way, heat can be efficiently transported to the heat radiating part 11 side without storing heat until the heat transport part 7 reaches a predetermined temperature.

  On the other hand, the heat storage unit 9d starts to store heat from a lower temperature. By doing in this way, when the temperature of the heat transport part 7 rises and the heat storage by the heat storage part 9c is insufficient, the heat storage part 9d heat storage is immediately started, and the heat storage to the heat storage part 9c is maintained and the heat dissipation part The heat dissipation from 11 can be maintained. In addition, what is necessary is just to provide the fin 17 in the thermal storage part 9a, 9b as needed, respectively.

  According to the fourth embodiment, an effect similar to that of the second embodiment can be obtained. Moreover, it can divide | segment into the thermal storage part 9c, 9d, and can thermally convey a heat | fever to a thermal radiation part efficiently by laminating | stacking a thermal storage part in two steps.

  Next, the motor structure 40 using the heat exchange module described above will be described. The motor structure 40 includes a heat exchange module 40a, a motor 41, and the like. The case constituting the motor 41 is integrally formed in a substantially cylindrical shape, and the coil 43 is accommodated in the approximate center. The coil 43 becomes a heat generating part.

  A hole is provided in the outer periphery of the coil 43 and the heat pipe 13 is inserted. The block portion 51 on the outer peripheral portion of the coil 43 and the heat pipe 13 partially embedded in this constitute the heat transport portion 45. A heat radiating portion 47 is provided at the end of the heat pipe 13 protruding from the block portion 51. The heat dissipation part 47 is configured by joining a plurality of fins to the heat pipe 13.

  A heat storage unit 49 is provided on the outer periphery of the block unit 51. The heat storage part 49 is configured by filling the heat storage member 15 in the hollow part. Note that the heat storage section 49 may be formed with fins that open in the heat transport direction. By doing in this way, the whole case can be integrally formed by an extrusion process or a drawing process. Note that both ends of the heat storage unit 49 are closed by lids not shown.

  Such a motor structure 40 can transport heat from the coil 43 to the heat radiating section 47 by the heat transport section 45 and store heat by the heat storage section 49. At this time, the heat storage unit 49 is configured integrally with the heat transport unit 7. For this reason, it is not necessary to use another thermal interface material etc. between the heat storage part 9 and the heat transport part 7, and thermal resistance can be made small.

  In addition, as a structure of the thermal storage part 49, you may divide into multiple as mentioned above.

  Next, the heating system 50 using the heat exchange module described above will be described. The heating system 50 is a heating system for automobiles. The heating system 50 includes a plurality of heat exchange modules 1a, 1b, and 1c, an air flow path 57, an air ejection unit 53, and the like. Note that any of the heat exchange modules 1, 10, 20, and 30 described above may be applied to the heat exchange modules 1a, 1b, and 1c. Further, the motor structure 40 may be applied to the heat exchange module 1a combined with the motor 55a. Further, the number of heat exchange modules arranged is not limited to the illustrated example.

  A plurality of heat exchange modules 1a, 1b, and 1c are provided, and a motor 55a, a DCDC converter 55b, and an inverter 55c, which are heat generating parts, are joined to each other. The heat radiating portions 11 of the heat exchange modules 1a, 1b, and 1c are arranged in the air flow path 57. At this time, the heat exchange modules 1a, 1b, and 1c are arranged in order from the upstream side of the air flowing through the air flow path 57.

  For example, outside air is taken into the air channel 57 from the upstream side (in the direction of arrow E in the figure). The air taken into the air flow path 57 is first subjected to heat exchange with the heat radiating portion 11 of the heat exchange module 1a. Next, after the heat exchange with the heat radiating units 11 is completed in the order of the heat exchange modules 1b and 1c, the warmed air is sent from the air ejection unit 53 into the vehicle (in the direction of arrow F in the figure). In addition, air is discharged | emitted to external air except the time of heating use.

  Here, the heat storage member filled in each of the heat exchange modules 1a, 1b, and 1c has a higher melting point in the order of the heat exchange modules 1a, 1b, and 1c. That is, the melting point of the heat storage member used in the heat exchange module 1a is the lowest, and the melting point of the heat storage member used in the heat exchange module 1c is the highest. Therefore, the heat storage part of the heat exchange module 1a functions from a lower temperature.

  Moreover, since the thermal radiation part 11 of the heat exchange module 1a is arrange | positioned in the most upstream side of the air flow path 57, the temperature of air is also low and heat exchange efficiency is excellent. Therefore, since the heat exchange module 1a has a large amount of heat radiation and the timing for starting the heat storage is early, the cooling efficiency of the motor 55a to be cooled is large. Similarly, the cooling efficiency of the DCDC converter 55b and the inverter 55c, which are the objects of cooling, deteriorates in the order of the heat exchange modules 1b and 1c.

  On the other hand, since the motor 55a is vulnerable to heat, high cooling efficiency is required. Therefore, the highest cooling efficiency is required for the heat exchange module 1a. On the other hand, the heat resistance increases in the order of the DCDC converter 55b and the inverter 55c. For this reason, even if the temperature at which the heat storage unit functions is increased so that the temperature of the device rises, there is no risk of device failure. Therefore, when the device is in use at a temperature lower than the heat-resistant temperature, the heat can be effectively used by transporting the heat to the heat radiating unit without storing the heat in the heat accumulating unit. Thus, while arrange | positioning from the upstream of the air flow path 57 in order from the apparatus weak with respect to a heat | fever, heat | fever can be thermally radiated efficiently by making melting | fusing point of a thermal storage member high in order from an upstream.

  According to the present embodiment, it is possible to cool the equipment that is the heat generating portion and to effectively use the generated heat for heating the vehicle interior. Moreover, the heat of each apparatus can be effectively conveyed to the air side by making arrangement | positioning of an apparatus and the structure of the heat exchange module 1a, 1b, 1c used for this appropriate. For this reason, an efficient heating system can be obtained.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs.
