Description

[Technical field]

[0001] The present invention relates to a conductor member with a cooling structure that connects a component terminal of an electric / electronic component to an electrical connection target while cooling itself. [Background technology]

[0002] Conventionally, a conductor member with a cooling structure is known that adds its own cooling function to a conductor member that connects the component terminal of an electric / electronic component to an electrical connection target (see, for example, Patent Document 1). The conductor member with a cooling structure of Patent Document 1 uses a conductive pipe as the conductor member, and has a configuration in which both ends are crushed to form connection parts with the component terminal of the electric / electronic component and the electrical connection target. The electrical connection is made by the conductive pipe itself, and cooling is achieved by a coolant flowing inside the pipe. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-018661 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the above-mentioned conductor member with cooling structure using the conductive pipe, the connection part formed by crushing the end part tends to be separated from the refrigerant flowing in the hollow part. On the other hand, in this conductor member with cooling structure, heat generation is higher at the connection part with the component terminal of the electric / electronic component than in other parts. However, since the connection part tends to be separated from the refrigerant as described above, the above-mentioned conductor member with cooling structure has a problem that the cooling efficiency for this connection part is low.

[0005] Therefore, in view of the above-mentioned problems, an object of the present invention is to provide a conductor member with a cooling structure capable of efficiently cooling a connection portion with a component terminal of an electric / electronic component. [Means for solving the problem]

[0006] In order to solve the above problems, the conductor member with a cooling structure is characterized in comprising: a cooling pipe through which a refrigerant flows; and a conductor member formed in a band shape from a conductive metal, one end of which is connected to a component terminal of a specified electrical / electronic component and the other end of which is connected to an electrical connection object of the electrical / electronic component to conduct electricity, and to which the cooling pipe is fixed so as to contact the connection portion with the component terminal. Effect of the Invention

[0007] According to the above-mentioned conductive member with a cooling structure, the connection portion with the component terminal of the electric / electronic component can be efficiently cooled. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of a conductor member with a cooling structure will be described. First, a first embodiment will be described.

[0010] Fig. 1 is a perspective view showing a conductor member with a cooling structure according to a first embodiment, and Fig. 2 is a plan view of a connection portion between a component terminal of an electric / electronic component and a conductor member in the conductor member with a cooling structure shown in Fig. 1, as viewed from the direction of arrow V11 in Fig. 1. Fig. 3 is a cross-sectional view of a connection portion between a component terminal of an electric / electronic component and a conductor member shown in Fig. 2, taken along line V12-V12 in Fig. 1. And Fig. 4 is a perspective view showing two conductor plates constituting the conductor member shown in Figs. 1 to 3 arranged side by side.

[0011] The conductor member 1 with a cooling structure in this embodiment is a member for connecting a pair of component terminals E11 in a relay, which is an electric / electronic component E1, to an electrical connection target of the electric / electronic component E1. The conductor member 1 with a cooling structure includes one cooling pipe 11 and a pair of conductor members 12 connected one-to-one to the pair of component terminals E11 to fix the cooling pipe 11.

[0012] The cooling pipe 11 is a round pipe bent into a U-shape midway, and a refrigerant flows inside. In this embodiment, water, which is a fluid having electrical conductivity, is used as the refrigerant. Moreover, a metal pipe having electrical conductivity is used as the cooling pipe 11. An example of the metal pipe is a copper pipe.

[0013] The pair of conductor members 12 are formed in a strip shape from conductive metal, one end of which is connected to the component terminal E11 of the electric / electronic component E1, and the other end of which is connected to an electrical connection target to conduct electricity. The cooling pipe 11 is fixed to each conductor member 12 by the following structure so as to contact the connection portion 12a with the component terminal E11. That is, in this embodiment, the conductor member 12 has two strip-shaped conductor plates 121 that are overlapped with each other, and the cooling pipe 11 is sandwiched and fixed between the two conductor plates 121. Each of the two conductor plates 121 has a pipe holding groove 121a formed on the opposing surface 121b when overlapped, which holds a part of the cooling pipe 11 in the thickness direction D12, specifically, half of the cooling pipe 11, inside, so as to cross the connection portion 12a of the conductor member 12 in the width direction D11.

[0014] In this embodiment, the connection portion 12a of the conductor member 12 is screwed to the component terminal E11 by the screw E12. Each of the two conductor plates 121 has a screw through hole 121d for screwing in an end portion 121c corresponding to the connection portion 12a, and a pipe holding groove 121a is formed so as to cross the end portion 121c next to the screw through hole 121d. Since the cooling pipe 11 is a round pipe, the pipe holding groove 121a has a semicircular cross section. In addition, both the conductor side contact surface 121a-1, which is the inner surface of the pipe holding groove 121a that contacts the cooling pipe 11, and the pipe side contact surface 111 that contacts the conductor side contact surface 121a-1 of the cooling pipe 11 are subjected to an insulating treatment by insulating paint or the like. Then, the cooling pipe 11 is fixed to the pipe holding groove 121a by adhesion or the like, and the two conductive plates 121 are joined to each other by a conductive adhesive, welding, or the like. The two conductive plates 121 may be joined by adhesive bonding using an insulating adhesive or the like. In this case, of the two conductive plates 121, one conductive plate 121 that is in direct contact with the component terminal E11 contributes to conduction with the electrical connection target.

[0015] In this embodiment, the other end of the conductor member 12 is also connected to an electrical connection target by screw fastening, and each conductor plate 121 has a screw through hole 121e formed on this other end for screw fastening.

[0016] In this embodiment, the pair of conductor members 12 are arranged to extend in the arrangement direction D13 of the pair of component terminals E11. The cooling pipe 11 is bent into a U-shape between the pipe holding groove 121a of one conductor member 12 and the pipe holding groove 121a of the other conductor member 12.

[0017] According to the conductor member 1 with a cooling structure of the first embodiment described above, the cooling pipe 11 is fixed to the conductor member 12 so as to contact the connection portion 12a with the component terminal E11 of the electric / electronic component E1. By fixing the cooling pipe 11 at such a position, heat generated at the connection portion 12a with the component terminal E11 is easily transferred to the refrigerant of the cooling pipe 11, and the connection portion 12a can be efficiently cooled.

[0018] In this embodiment, the refrigerant is water, which is a fluid having electrical conductivity, and the cooling pipe 11 is a metal pipe having electrical conductivity. Insulation treatment is applied to both the conductor side contact surface 121a-1 of the conductor member 12 and the pipe side contact surface 111 of the cooling pipe 11. With this configuration, it is possible to use general water, copper pipe, or the like as the conductive refrigerant and cooling pipe 11 while preventing the connection portion 12a with the component terminal E11 of the electric / electronic component E1 from being short-circuited to an unintended location via the refrigerant or cooling pipe 11.

[0019] In this embodiment, the conductor member 12 is configured to sandwich and fix the cooling pipe 11 between two conductor plates 121, and each conductor plate 121 is formed with a pipe holding groove 121a for holding a part of the cooling pipe 11 inside. According to this configuration, by sandwiching the cooling pipe 11 between the two conductor plates 121 so that it fits in the pipe holding groove 121a, the contact area between the cooling pipe 11 and the conductor member 12 can be increased, and the cooling efficiency can be further improved. Also, by sandwiching the cooling pipe 11 between the two conductor plates 121, the fixing strength of the cooling pipe 11 to the conductor member 12 can be increased.

[0020] In this embodiment, the pipe holding groove 121a is formed so as to cross adjacent to the screw through hole 121d for screw fastening in each conductive plate 121. With this configuration, the cooling pipe 11 can be effectively brought into contact with the connection portion 12a which is connected to the component terminal E11 of the electric / electronic component E1 by screw fastening.

[0021] In this embodiment, the cooling pipe 11 is a single pipe having a portion fixed to each of the pair of conductor members 12, and is bent into a U-shape between the pipe holding groove 121a of one conductor member 12 and the pipe holding groove 121a of the other conductor member 12. With this configuration, the pair of connection parts 12a connected to the pair of component terminals E11 of the electric / electronic component E1 can be efficiently cooled by the single cooling pipe 11.

[0022] Next, a second embodiment will be described. The second embodiment differs from the first embodiment in the configuration of the conductor member. The following description of the second embodiment will focus on the differences from the first embodiment.

[0023] Fig. 5 is a perspective view showing a conductor member with a cooling structure according to a second embodiment, and Fig. 6 is a perspective view showing the conductor member shown in Fig. 5 from the front and back sides. Note that in Fig. 5, components equivalent to those of the first embodiment shown in the perspective view of Fig. 1 are given the same reference numerals as in Fig. 1 only for those elements necessary for explanation, and hereinafter, redundant explanations of those components will be omitted.

[0024] The conductor member 2 with a cooling structure of the second embodiment is similar to the first embodiment described above in that it includes one cooling pipe 11 and a pair of conductor members 22 that are connected one-to-one to a pair of component terminals E11 of an electric / electronic component E1 to fix the cooling pipe 11. However, this embodiment differs from the first embodiment in that the conductor member 22 is a sheet metal member having a band plate portion 221 and a pair of side wall ribs 222.

[0025] The band plate portion 221 is a band-shaped portion having a connection portion 22a with the component terminal E11 at one end, and a screw through hole 221c for screw fastening is formed in the connection portion 22a, and a screw through hole 221e for screw fastening to an electrical connection target is also formed on the other end side. The pair of side wall ribs 222 are portions erected on a pair of side edges of the band plate portion 221, and in this embodiment, each side wall rib 222 is formed by sheet metal processing in which a side edge portion of a metal band plate wider than the band plate portion 221 is bent at a right angle. Then, each of the pair of side wall ribs 222 is formed with a pipe holding portion 222a that passes through and holds the cooling pipe 11 so as to contact the connection portion 22a of the band plate portion 221 across the width direction D11. The pipe holding portion 222a is a portion having a notch-like shape cut in an arc shape from the edge of each of the pair of side wall ribs 222. The pipe holding portions 222a of the pair of side wall ribs 222 are formed at positions coaxial with each other in the width direction D11, and a part of the cooling pipe 11 is fixed so as to pass through the pair of pipe holding portions 222a.

[0026] Here, the connection portion 22a of the band plate portion 221 has a terminal contact surface 221a that contacts the component terminal E11 on the front and back sides opposite to the protruding side of the sidewall rib 222, and a pipe contact surface 221b that contacts the cooling pipe 11 on the protruding side of the sidewall rib 222. A pipe passing groove 221d is formed in the width direction D11 on the pipe contact surface 221b, through which the cooling pipe 11 passes with a part of the cooling pipe 11 housed inside in the thickness direction D12. Each of the pair of sidewall ribs 222 has a pipe holding portion 222a formed at a position in the rib height direction D14 where a part of the cooling pipe 11 is housed in the pipe passing groove 221d. The pipe passing groove 221d is a circular groove that receives a part of the round cooling pipe 11 and has a groove cross section that is an arc-shaped groove that forms a part of the arc-shaped shape of the pipe holding portion 222a. The pipe passing groove 221d and the pair of pipe holding portions 222a are formed by punching the pair of side wall ribs 222 while cutting the pipe contact surface 221b with a predetermined tool.

[0027] In the conductor member 22 of this embodiment, the inner edge of the pipe holding portion 222a having a notched shape in the sidewall rib 222 and the inner surface of the pipe passing groove 221d in the band plate portion 221 form a conductor side contact surface 22b that comes into contact with the cooling pipe 11. The conductor side contact surface 22b and the pipe side contact surface 111 of the cooling pipe 11 are each subjected to an insulation treatment in which an insulating paint is applied. Then, the conductor member 22 and the cooling pipe 11 are fixed to each other by adhesion or the like.

[0028] It goes without saying that the conductive member 2 with a cooling structure according to the second embodiment described above can also efficiently cool the connection portion 22a with the component terminal E11 of the electric / electronic component E1, similarly to the first embodiment described above.

[0029] In the present embodiment, the conductor member 22 is a portion having the band plate portion 221 and a pair of sidewall ribs 222, and a pipe holding portion 222a having a notched shape is formed in each of the pair of sidewall ribs 222. With this configuration, the conductor member 22 can be made into a thin-walled structure including the band plate portion 221 and the pair of sidewall ribs 222. With this thin-walled structure, it is possible to reduce the material cost of the conductor member 22 and reduce the weight of the conductor member 22, as compared to forming the conductor member 22 into a thick plate shape.

[0030] In this embodiment, a pipe passing groove 221d is formed on the pipe contact surface 221b of the connection portion 22a of the band plate portion 221. The pipe holding portion 222a of each side wall rib 222 is formed at a position in the rib height direction D14 where a part of the cooling pipe 11 fits in the pipe passing groove 221d. According to this configuration, the cooling pipe 11 held by the pipe holding portion 222a is brought into contact with the pipe contact surface 221b of the band plate portion 221 so as to fit in the pipe passing groove 221d, thereby increasing the contact area between the cooling pipe 11 and the conductor member 22 and further improving the cooling efficiency.

[0031] In this embodiment, the cooling pipe 11 is bent into a U-shape between the pipe holding portion 222a on one side of the pair of conductor members 22 connected to the pair of component terminals E11 in a one-to-one manner and the pipe holding portion 222a on the other side of the pair of conductor members 22. With this configuration, the pair of connection portions 22a connected to the pair of component terminals E11 in the electric / electronic component E1 can be efficiently cooled by the single cooling pipe 11.

[0032] Next, a third embodiment will be described. The third embodiment is a modified example of the second embodiment described above, and the pipe holding portion of the conductor member is different from that of the second embodiment. The following description of the third embodiment will focus on the differences from the second embodiment.

[0033] Fig. 7 is a perspective view of the conductor member according to the third embodiment, seen from both the front and back sides. In Fig. 7, components equivalent to those of the second embodiment shown in the perspective view of Fig. 6 are denoted by the same reference numerals as in Fig. 6 only for those components necessary for the explanation, and duplicate explanations of those components will be omitted below.

[0034] The conductor member 32 in the third embodiment is different from the second embodiment in the shape of the pipe holding portion 322a provided on the pair of sidewall ribs 222 and the pipe passing groove 321d provided on the pipe contact surface 221b of the connection portion 22a of the band plate portion 221. In this embodiment, the pipe holding portion 322a is not notched but has a through-hole shape that coaxially penetrates the pair of sidewall ribs 222. The through-hole as the pipe holding portion 322a has a shape in which a semicircular hole portion on the edge side of the sidewall rib 222 and a rectangular hole portion on the band plate portion 221 side are connected in the rib height direction D14. The pipe passing groove 321d provided on the pipe contact surface 221b of the connection portion 22a is a portion that is connected to the rectangular hole portion in the pipe holding portion 322a at both ends in the width direction D11, and is a rectangular groove with a rectangular groove cross section. In the present embodiment, the pipe passing groove 321d and the pair of pipe holding portions 322a are also formed by punching the pair of side wall ribs 222 while cutting the pipe contact surface 221b with a predetermined tool, similarly to the second embodiment.

[0035] Also in this embodiment, the inner edge of the pipe holding portion 322a and the inner surface of the pipe passing groove 321d in the band plate portion 221 form a conductor side contact surface 32b that comes into contact with the cooling pipe 11. An insulating treatment is performed by applying an insulating paint to each of the conductor side contact surface 32b and the pipe side contact surface 111 of the cooling pipe 11. Then, the conductor member 32 and the cooling pipe 11 are fixed to each other by adhesion or the like.

[0036] It goes without saying that the third embodiment described above can efficiently cool the connection portion 22a between the component terminal E11 of the electric / electronic component E1, similarly to the second embodiment described above, that is, similarly to the first embodiment.

[0037] Next, a fourth embodiment will be described. The fourth embodiment differs from the first embodiment in the mounting structure of the cooling pipe to the conductor member. The following description of the fourth embodiment will focus on the differences from the first embodiment.

[0038] Fig. 8 is a perspective view showing a conductor member with a cooling structure according to a fourth embodiment, Fig. 9 is a plan view of the conductor member with a cooling structure shown in Fig. 8, seen from the direction of arrow V13 in Fig. 8, and Fig. 10 is a perspective view showing the conductor member shown in Fig. 8. Fig. 11 is a schematic diagram showing how a cooling pipe is held by the conductor member shown in Fig. 10. In Figs. 8 to 10, the same reference numerals as in Figs. 1 to 4 are used for components equivalent to those of the first embodiment shown in Figs. 1 to 4, and only those components necessary for explanation are given, and duplicate explanations of those components will be omitted below.

[0039] The conductor member 4 with a cooling structure of the fourth embodiment is a member for connecting each of a pair of component terminals E11 in a relay, which is an electric / electronic component E1, to an electrical connection target of the electric / electronic component E1, similarly to the first embodiment described above. However, in this embodiment, one cooling pipe 41 is attached to each of a pair of conductor members 42 connected one-to-one to a pair of component terminals E11.

[0040] Each cooling pipe 41 is fixed to each conductor member 42 so that at least a portion of each cooling pipe 41 extends in a length direction D41 of the conductor member 42 while contacting a connection portion 42a of the conductor member 42.

[0041] Each conductor member 42 includes a band plate portion 421 having a connection portion 42a with the component terminal E11 at one end and having screw through holes 421a, 421e for screw fastening formed at the connection portion 42a and the other end, and a bent holding portion 422 for fixing the cooling pipe 41. The bent holding portion 422 is provided upright on both of a pair of side edges of the band plate portion 421 and is bent toward the center of the band plate portion 421 in the width direction D11 to sandwich and hold the extending portion 411 of the cooling pipe 41 in the length direction D41 between the band plate portion 421 and the bent holding portion 422.

[0042] Each cooling pipe 41 includes a pair of extending portions 411 held by a pair of bending holding portions 422, and a U-shaped bent portion 412. The U-shaped bent portion 412 is a portion that connects the connecting portion 42a side of each of the pair of extending portions 411 so as to surround the periphery of the screw through hole 421a in a U-shape and contacts the connecting portion 42a.

[0043] In this embodiment, the pair of extending portions 41 of the cooling pipe 41 contact the inner surfaces of the band plate portion 421 and the pair of bending holding portions 422, and the U-shaped bending portion 412 contacts the connection portion 42a. Therefore, the pair of extending portions 41 and the U-shaped bending portion 412 are all insulated by insulating paint. Also, on the conductor member 42 side, the surfaces of the protruding sides of the bending holding portions 422 on the front and back sides of the band plate portion 421 and the inner surfaces of the pair of bending holding portions 422 are insulated by insulating paint. Due to these insulating treatments, in this embodiment as well, a conductive metal pipe such as a copper pipe is used as the cooling pipe 41, and water, which is a conductive fluid, is used as the refrigerant.

[0044] 11, the cooling pipe 41 is strongly pressed against the band plate portion 421 by a spring force F41 resulting from the bending structure of the bending holding portion 422. The cooling pipe 41 is fixed to the conductor member 42 by utilizing the spring force F41 at the bending holding portion 422 without relying on adhesion or the like.

[0045] It goes without saying that the fourth embodiment described above can also efficiently cool the connection portion 42a with the component terminal E11 of the electric / electronic component E1, similarly to the first embodiment described above.

[0046] In this embodiment, the conductor member 42 includes a band plate portion 421 and bent holding portions 422 provided on both sides thereof for holding an extending portion 411 of the cooling pipe 41 in the length direction D41 between the band plate portion 421 and the conductor member 42. This configuration increases the contact area between the conductor member 42 and the cooling pipe 41, thereby enabling efficient cooling. As shown in Fig. 11, the cooling pipe 41 is strongly pressed against the band plate portion 421 by a spring force F41 resulting from the bending structure of the bent holding portions 422, and this also improves the cooling efficiency of the cooling pipe 41.

[0047] In this embodiment, the cooling pipe 41 includes a pair of extending portions 411 and a U-shaped bent portion 412 that connects the extending portions 411 to surround the periphery of the screw through hole 421c in a U-shape and contacts the connection portion 42a. With this configuration, the U-shaped bent portion 412 of the cooling pipe 41 surrounds the periphery of the screw through hole 421c for screw fastening in a U-shape and contacts the connection portion 42a, so that the contact area between the cooling pipe 41 and the connection portion 42a can be increased, and the cooling efficiency can be further improved.

[0048] Next, a fifth embodiment will be described. The fifth embodiment is a modified example of the fourth embodiment described above, and the shape of the cooling pipe attached to the conductor member is different from that of the fourth embodiment. The fifth embodiment will be described below, focusing on the differences from the fourth embodiment.

[0049] Fig. 12 is a plan view of a conductor member with a cooling structure according to a fifth embodiment, equivalent to Fig. 9. In Fig. 12, components equivalent to those of the fifth embodiment shown in Figs. 8 to 9 are denoted by the same reference numerals as in Figs. 8 to 9 only for components necessary for the explanation, and hereinafter, redundant explanations of those components will be omitted.

[0050] In the conductor member 5 with a cooling structure of the fifth embodiment, two cooling pipes 51 are attached to each of a pair of conductor members 42 similar to those of the fourth embodiment, which are connected one-to-one to a pair of component terminals E11 of an electric / electronic component E1, so as to be aligned parallel to the width direction D11. Each attached cooling pipe 51 extends linearly from one of the pair of conductor members 42 to the other and is attached as follows. That is, each cooling pipe 51 leaves the bent holding portion 422 of one conductor member 42, contacts a pair of connection portions 42a, and advances straight in the arrangement direction D51 of the pair of component terminals E11 to reach the bent holding portion 422 of the other conductor member 42. Each cooling pipe 51 is arranged in this manner and held by the pair of bent holding portions 422.

[0051] It goes without saying that the fifth embodiment described above can also efficiently cool the connection portion 42a with the component terminal E11 of the electric / electronic component E1, similarly to the first embodiment described above.

[0052] In this embodiment, the cooling pipe 51 runs straight from the bent and held portion 422 of one conductor member 42 to the bent and held portion 422 of the other conductor member 42 while contacting the pair of connecting portions 42a along the way. With this configuration, the pair of connecting portions 42a connected to the pair of component terminals E11 of the electric / electronic component E1 can be collectively and efficiently cooled.

[0053] In this embodiment, two straight cooling pipes 51 are arranged in parallel in the width direction D11 and contact the pair of connecting portions 42a. With this configuration, the two cooling pipes 51 work together to cool the pair of connecting portions 42a, thereby improving the cooling efficiency.

[0054] The first to fifth embodiments described above are merely representative forms of the conductor member with a cooling structure, but the conductor member with a cooling structure is not limited thereto and can be modified in various ways.

[0055] For example, in the above-described embodiment, as an example of the conductor member with a cooling structure, conductor members 1,...,5 for connecting each of a pair of component terminals E11 in a relay, which is an electric / electronic component E1, to an electrical connection target are illustrated. However, the conductor member with a cooling structure is not limited to this, and the electric / electronic component to be connected may be an electric component other than a relay, or may be another electronic component.

[0056] In the above-described embodiment, as an example of the conductor member with a cooling structure, the liquid-cooled conductor members with a cooling structure 1,...,5 in which water, which is a conductive liquid, is flowed as a coolant through the cooling pipes 11, 41, 51 are exemplified. However, the conductor member with a cooling structure is not limited to this, and the coolant may be a non-conductive liquid or a gas for air cooling.

[0057] In the above-described embodiment, as an example of a conductor member with a cooling structure, conductor members with a cooling structure 1,...,5 including a pair of conductor members 12,...,42 are given. However, the conductor member with a cooling structure is not limited to this, and may include only one conductor member, or three or more conductor members, etc.

[0058] In the above-described embodiment, the cooling pipes are exemplified by round cooling pipes 11, 41, and 51 made of conductive metal pipes such as copper pipes. However, the cooling pipes are not limited to this, and may be made of non-conductive metal, resin, or the like, and may have a shape other than round, such as a square or other polygonal shape. When the cooling pipes are made of non-conductive metal, resin, or the like, insulation between the cooling pipes and the conductor member is not required.

[0059] In the above-described embodiment, as an example of a conductor member with a cooling structure, conductor members with a cooling structure 1..., 5 that have been subjected to an insulation treatment as follows are exemplified. That is, the insulation treatment here is performed on both the conductor side contact surfaces 22b, 121a-1 of the conductor members 12,..., 42 and the pipe side contact surface 111 of the cooling pipe 11, 41, 51. However, the conductor member with a cooling structure is not limited to this, and the insulation treatment may be performed on only one of the conductor side contact surface of the conductor member and the pipe side contact surface of the cooling pipe.
