  ADVANTAGE OF THE INVENTION According to this invention, in the heat exchanger which has a heat-transfer member and a fin, the heat exchanger etc. which can perform heat exchange (heat transport) with high efficiency between a fin and a heat-transfer member are provided. be able to.

It is a figure which shows the heat exchanger 1, (a) is a top view, (b) is a perspective view of the cover member 3. FIG. The bottom view which shows the heat exchanger 1. FIG. It is a figure which shows the header 9, and is the sectional view on the AA line of Fig.1 (a) in the header 9 vicinity. The C section enlarged view of FIG. The system block diagram which shows the heating system 30. FIG. The figure which shows the heat exchanger 1a. The figure which shows the heat exchanger 1b. The figure which shows the heat exchanger 1c.

  Hereinafter, a heat exchanger according to an embodiment of the present invention will be described. FIG. 1 is a view showing a heat exchanger 1, FIG. 1 (a) is a plan view showing a state where a lid member 3 is mounted, and FIG. 1 (b) is a lid member 3 relative to FIG. 1 (a). It is a figure which shows the state which saw through. FIG. 2 is a bottom view of the heat exchanger 1.

  The heat exchanger 1 includes a main body 11, a lid member 3, a heat pipe 17, and the like. The heat exchanger 1 has a high temperature side channel 19 that is a first channel and a low temperature side channel 21 that is a second channel. In each flow path, a plurality of fins 15 are integrally formed on the base portion 13 of the main body 11. The main body 11 is composed of a member having good thermal conductivity, and is made of, for example, aluminum.

  The plurality of fins 15 are provided in the direction in which the fluid flows (from the right side to the left side in FIG. 1B). At this time, the fins 15 provided on the downstream side (left side) of the fins 15 on the upstream side (right side) are arranged so as to be shifted from each other substantially vertically (up and down direction in the drawing). That is, the fins 15 are arranged in a staggered pattern from the upstream side toward the downstream side. The fins 15 are provided in parallel with the direction in which the fluid flows. Further, the fins 15 are arranged at substantially equal intervals in a direction substantially perpendicular to the direction in which the fluid flows.

  As shown in FIG. 2, a groove 23 is formed on the bottom surface side of the base portion 13. The groove 23 is provided so as to straddle the high temperature side channel 19 and the low temperature side channel 21. A heat pipe 17 is provided in the groove 23. The heat pipe 17 is fixed in the groove 23 by solder or the like not shown. That is, the heat pipe 17 is arranged in a direction substantially perpendicular to the direction of fluid flow in the flow path (substantially left-right direction in the figure).

  In addition, if it is a means (heat-transfer member) which can perform heat transport, it may replace with the heat pipe 17 and another form (for example, high heat conductive material etc.) may be used, However, A heat pipe is used preferably. The heat pipe 17 can transmit a heat | fever by evaporation and condensation of a solvent, for example, arrange | positioning a solvent inside the metal which sealed the edge part. Many heat pipes are mainly used in which water is put inside copper. For this reason, heat can be transferred without using a power source, and since it is hermetically sealed, water is not reduced, so that maintainability is excellent. A thermosiphon type heat pipe is more preferable.

  Further, when the high temperature side channel 19 is disposed below and the low temperature side channel 21 is disposed above, the heat pipe 17 extends from the lower end of the high temperature side channel 19 to the upper end of the low temperature side channel 21. Be placed. The hydraulic fluid in the heat pipe 17 vaporizes by taking heat in the high temperature side channel 19 and condenses in the low temperature side channel 21 to release heat. The hydraulic fluid aggregated at the top falls downward and repeats vaporization. Thus, the heat received from the fluid flowing through the high temperature side channel 19 can be transported to the upper low temperature side channel 21 side (in the direction of arrow B in the figure). In addition, the thing which has arrange | positioned the high temperature side flow path 19 below, has arrange | positioned the low temperature side flow path 21 upward, and connected the fluid path | route to each flow path is called a heat exchange module.

The lid member 3 is placed on the main body 11. That is, by attaching the lid member 3 to the main body 11, the high temperature side flow path 19 and the low temperature side flow path 21 are formed. The lid member 3 is provided with fluid inlets 5a and 5b serving as fluid inlets to the high temperature side channel 19 and the low temperature side channel 21 and fluid outlets 7a and 7b serving as fluid outlets.
1 and 2, the fluid inlets 5a and 5b of the high temperature side channel 19 and the low temperature side channel 21 are arranged on the same side, and the fluid flows in the high temperature side channel 19 and the low temperature side channel 21. However, the fluid inlets 5a and 5b of the high temperature side channel 19 and the low temperature side channel 21 are arranged on opposite sides, and the flow direction of the fluid in the high temperature side channel 19 and the low temperature side channel 21 is determined. It is also possible to reverse the direction. In this case, improvement in heat transport performance can be expected.

  In the high temperature side channel 19, the fluid inlet 5b is arranged at the lower part of the channel, and the fluid outlet 7b is arranged at the upper part of the channel. Moreover, in the low temperature side flow path 21, the fluid inlet 5a is arrange | positioned at the upper part of a flow path, and the fluid outlet 7a is arrange | positioned at the lower part of a flow path. As described above, by arranging either one of the fluid inlet and the outlet at the upper part of each flow path, the air can be efficiently extracted when the fluid flows.

  In addition, headers 9 are provided at the fluid inlets 5a and 5b and the fluid outlets 7a and 7b. FIG. 3 is an enlarged view of the vicinity of the header 9 in the cross-sectional view taken along the line AA in FIG. The header 9 has a space in which the fluid cross-sectional area of the fluid becomes large. The direction of the flow of the fluid flowing into the header 9 from the fluid inlet 5a is expanded by the header 9, and flows into the flow path. By providing the header 9 in this way, the fluid can flow through the entire flow path. The header 9 may be formed only on one of the fluid inlets 5a and 5b or the fluid outlets 7a and 7b.

  The heat pipe 17 (groove 23) is disposed at the fin 15 site. That is, the fins 15 are aligned along the heat pipe 17.

  FIG. 4 is an enlarged view of a portion C in FIG. In the cross section, the heat pipe 17 is provided so as to protrude beyond the base portion inner surface 13a of the base portion 13 in the flow path direction (upper side in the figure). That is, the depth of the groove 23 is deeper than the thickness of the base portion 13. Here, in the cross section, it is desirable that more than half (D in the drawing) of the entire circumference of the heat pipe 17 protrude above the base portion inner surface 13a. That is, when the cross section of the heat pipe is circular, the value obtained by subtracting 1/2 of the outer diameter of the heat pipe 17 from the depth of the groove 23 is set to be equal to or greater than the thickness of the base portion 13. By arrange | positioning in this way, the heat from the heat pipe 17 can be efficiently transmitted to the fin 15 side.

  Next, a heating system using the heat exchanger 1 will be described. FIG. 5 is a system configuration diagram showing the heating system 30. FIG. 5 is a conceptual diagram viewed from the side of the system. The heating system 30 mainly includes a heat source side cooling path 31, a heating side heating path 33, an air path 45, the heat exchanger 1, and the like. The heating system 30 is a heating system for automobiles.

  The heat source side cooling path 31 is a path for cooling a driving unit of an automobile such as an engine or a motor. In the heat source side cooling path 31, cooling water or the like circulates as a heat medium. The heat source side cooling path 31 is provided with a motor 35, a pump 39, a cooling unit 37, and the like.

  The motor 35 is a drive unit of the automobile and is a part that becomes a heat source. In addition, in this embodiment, although the example of the electric vehicle whose heat source is only the motor 35 is shown, this invention is not limited to this. For example, a normal engine may be used as the heat source, or both of them may be arranged. Further, the heat source is not limited to the drive unit, but may be any part that generates heat during driving of an automobile.

  The pump 39 circulates the heat medium in the heat source side cooling path 31 (in the direction of arrow E in the figure). The cooling unit 37 is a part that cools the heat medium in the heat source side cooling path 31. The cooling unit 37 is, for example, a radiator or the like, and releases heat to the outside.

  The heating side heating path 33, which is a heat utilization path that uses heat from the heat source side cooling path, is a path that heats air for heating the interior of the vehicle, for example. Water or the like circulates in the heating side heating path 33 as a heat medium. In the heating side heating path 33, a heater 41, a pump 43, a heat radiating portion 47, and the like are provided.

  The heater 41 is a part that heats the heat medium in the heating side heating path 33. The pump 43 circulates the heat medium in the heating side heating path 33 (in the direction of arrow F in the figure). The heat radiating unit 47 is a part that radiates heat of the heat medium in the heating side heating path 33 to the air in the air path 45. That is, the heat radiating portion 47 is formed at a portion where the heating side heating path 33 and the air path 45 intersect. In the air path 45, outside air or air taken from inside the vehicle flows. The air flowing in the air path 45 is heated by the heat radiating portion 47 and sent into the vehicle. That is, the air in the air path 45 is heat-exchanged with the heat medium in the heating side heating path 33.

  The heat source side cooling path 31 is connected to the high temperature side flow path 19 of the heat exchanger 1. Further, the low temperature side passage 21 of the heat exchanger 1 is connected to the heating side heating path 33. At this time, the heat exchanger 1 is arranged such that the high temperature side channel 19 is downward and the low temperature side channel 21 is upward (refer to FIG. 1 below).

  The heat medium in the heat source side cooling path 31 flows in the high temperature side flow path 19. At this time, the heat of the heat medium in the high temperature side channel 19 is transmitted to the heat pipe 17 through the fins 15. Further, heat is transported by the heat pipe 17 toward the upper low-temperature channel 21. In the low temperature side flow path 21, the heat released from the heat pipe 17 is transmitted to the heat medium in the heating side heating path 33 through the fins 15. As described above, the heat of the heat source side cooling path 31 can be transferred to the heating side heating path 33.

  Here, the heat pipe 17 heats from the heat source side cooling path 31 to the heating side heating path 33 side by being arranged so that the low temperature side path 21 is positioned higher than the high temperature side path 19. Although transported, heat is not transported from the heating side heating path 33 to the heat source side cooling path 31. In order to further enhance such an effect, it is desirable to dispose the heat pipe 17 in a substantially vertical direction.

  Next, the function of the heating system 30 will be described with reference to FIG. As described above, the heat medium in the heat source side cooling path 31 is circulated in the heat source side cooling path by the pump 39 (in the direction of arrow E in the figure). For example, the heat medium flowing through the motor 35 that is driving (generating heat) takes heat from the motor 35 and cools the motor 35.

  The heat medium heated by the motor 35 is heat-exchanged by the fins 15 of the high temperature side flow path 19, and a part of the heat is transmitted to the heat pipe 17. When heat is received at the lower end of the heat pipe 17, the heat pipe 17 transports heat to the upper low-temperature channel 21. Further, the heat is transferred to the heat medium in the heating side heating path 33 by the fins 15.

  In addition, the heat medium in the heat source side cooling path 31 that has transmitted heat to the heat exchanger 1 is sent to the cooling unit 37 and is cooled by releasing heat to the outside air or the like. The cooled heat medium is sent again to the motor 35 to cool the motor 35. The heat exchanger 1 is disposed between the motor 35 and the cooling unit 37 with respect to the circulation direction of the heat medium in the heat source side cooling path 31. This is to cause heat exchange with a higher temperature heat medium immediately after receiving heat from the motor 35. Note that the cooling unit 37 is not necessarily required if the heat transfer amount of the heat exchanger 1 is sufficient with respect to the heat generation amount of the motor 35.

  The heat medium in the heating side heating path 33 is circulated by the pump 43 (in the direction of arrow F in the figure). The heat medium heated by the heat exchanger 1 moves to the heater 41. When the temperature of the heat medium is not sufficient, the heat medium is further heated by the heater 41 as necessary.

  The heat medium heated to a predetermined temperature or higher releases heat to the air in the air path 45 at the heat radiating portion 47, and warm air is sent into the vehicle. As described above, it is possible to perform heating by effectively using the heat of the motor 35 and minimizing the heating by the heater 41. The heat exchanger 1 is disposed between the heat radiating unit 47 and the heater 41 with respect to the circulation direction of the heat medium in the heating side heating path 33. This is because heat exchange is performed with a lower temperature heat medium immediately after the heat radiation unit 47 radiates heat. Note that the heater 41 is not necessarily required if the heat transfer amount of the heat exchanger 1 is sufficient with respect to the heat dissipation amount of the heat dissipation portion 47.

  According to the present invention, heat generated from a heat source such as a drive unit such as the motor 35 can be efficiently transmitted to the heating side heating path 33, so that the heat medium in the heating side heating path 33 can be efficiently heated. it can. For this reason, the emitted-heat amount by the heater 41 can be suppressed.

  Moreover, in the heat exchanger 1, since the heat pipe 17 is arrange | positioned so that it may protrude in a flow path, the heat exchange efficiency of the heat pipe 17 and the heat medium in each flow path is high. In particular, the heat exchange efficiency between the fins 15 and the heat pipes 17 is good because the fins 15 are aligned along the heat pipes 17 so that the heat pipes 17 cut out part of the fins 15.

  Further, since the heat pipe 17 is provided in the groove 23 on the back side of the base portion 13, the heat pipe 17 does not come into contact with the fluid in the flow path. For this reason, even if it uses the copper heat pipe 17 for the main body 11 made from aluminum, it can prevent that corrosion progresses with a fluid.

  Moreover, since the high temperature side flow path 19 is arrange | positioned below and the low temperature side flow path 21 is arrange | positioned upwards, the heat pipe 17 can be arrange | positioned substantially perpendicularly. Therefore, the heat of the heat source side cooling path 31 can be transmitted to the heating side heating path 33 and the heat can be prevented from flowing back from the heating side heating path 33 to the heat source side cooling path 31.

  At this time, any one of the fluid inlets 5a, 5b or the fluid outlets 7a, 7b is arranged on the upper end side of the flow path, so that air can be easily released when the heat medium is introduced. Further, by providing the header 9 in at least one of the fluid inlets 5a and 5b and the fluid outlets 7a and 7b, the heat medium can be made to flow uniformly in the flow path.

  Next, another embodiment will be described. FIG. 6 is a diagram showing the heat exchanger 1a. In addition, in the following description, about the structure which show | plays the function similar to the heat exchanger 1 shown in FIGS. 1-4, the code | symbol similar to the heat exchanger 1 is attached | subjected, and the overlapping description is abbreviate | omitted. The heat exchanger 1a has substantially the same configuration as the heat exchanger 1, but the direction of the fins 15 is different.

  As described above, the fluid inlets 5a and 5b and the fluid outlets 7a and 7b are arranged so as to be shifted up and down in each flow path. Therefore, the fluid flowing in each flow path does not completely flow in the left-right direction of the heat exchanger 1a, but generally has a straight direction connecting the fluid inlets 5a, 5b and the fluid outlets 7a, 7b (see FIG. Middle H direction and I direction).

  In the heat exchanger 1a, the fins 15 are arranged in a direction parallel to the flow direction of the fluid (H direction and I direction in the drawing). That is, the direction in which the heat pipes 17 are arranged and the direction of the fins 15 are not orthogonal to each other and are formed at a predetermined angle. By doing in this way, the fin 15 becomes difficult to obstruct the flow of the fluid, and the fluid can flow more smoothly. In addition, if the arrangement of the fluid inlets 5a and 5b and the fluid outlets 7a and 7b is appropriately set, the direction of the fins 15 can be made the same in the high temperature side channel 19 and the low temperature side channel 21.

  The effect similar to the heat exchanger 1 can be acquired also by the heat exchanger 1a. The heat exchanger 1a can also be applied to the heating system 30 in the same manner as the heat exchanger 1.

  Moreover, the heat exchanger 1b shown in FIG. 7 can also be used. In the heat exchanger 1b, the heat pipe 17 is arranged directly in the flow path, not in the groove on the bottom surface side of the base portion 13. That is, the heat pipe 17 is disposed so as to penetrate the fins 15.

  Even in this case, it is assumed that the heat pipe 17 protrudes from the inner surface of the base portion 13 to the flow path side. In addition, it is assumed that the heat pipe 17 is arranged so as to cut out a part of the fin 15.

  The effect similar to the heat exchanger 1 can be acquired also by the heat exchanger 1b. Further, the heat exchanger 1 b can be applied to the heating system 30 in the same manner as the heat exchanger 1. In the heat exchanger 1b, countermeasures against corrosion due to fluid are required, but since the entire circumference of the heat pipe 17 can contribute to heat exchange with the fluid, heat exchange efficiency is good.

  Moreover, the heat exchanger 1c shown in FIG. 8 can also be used. The heat exchanger 1c uses a pair of heat exchangers and is integrated so that the base portions 13 face each other. The heat pipe 17 is sandwiched between the base portions 13. That is, the depth of each groove 23 is about ½ of the outer diameter of the heat pipe 17. Even in this case, in the cross section, the heat pipe 17 is arranged so as to protrude from the inner surface of the base portion 13 to the flow path side. That is, the thickness of the base portion 13 is thinner than the depth of the groove 23.

  A branch pipe 49 is connected to the pair of fluid inlets 5b. For example, the heat medium flowing through the heat source side cooling path 31 is branched by the branch pipes 49 and flows into the respective flow paths (high temperature side flow paths 19). In each channel, heat is transferred to the heat pipe 17 through the fins 15. The heat pipe 17 dissipates heat by transporting heat to the low temperature side flow path side (heating side heating path 33 side). As described above, heat can be transported.

  The effect similar to the heat exchanger 1 can be acquired also by the heat exchanger 1c. Further, the heat exchanger 1 c can be applied to the heating system 30 in the same manner as the heat exchanger 1. Further, in the heat exchanger 1c, the contact area between the heat medium and the fins 15 can be increased. Further, heat can be received and radiated from the heat medium on substantially the entire circumference of the heat pipe 17.

  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, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, the high temperature side channel 19 and the low temperature side channel 21 do not necessarily have to be formed integrally, and may be configured separately and connected by the heat pipe 17.
