Description

[Technical field]

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

[0002] Conventionally, a conductive member with a coolant passage is known that adds its own cooling function to a conductive member that connects the component terminal of an electric / electronic component to an electrical connection target (see, for example, Patent Document 1). The conductive member with a coolant passage of Patent Document 1 has a configuration in which both ends of a conductive pipe 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, the conductive member with a coolant passage using the above-mentioned conductive pipe is disadvantageous in terms of reducing the height because the thickness dimension is determined by the diameter of the pipe. Furthermore, if the current flowing during energization becomes large, the diameter of the pipe needs to be made larger, making it even more difficult to reduce the height.

[0005] Therefore, in view of the above-mentioned problems, an object of the present invention is to provide an electrically conductive member with a coolant passage that can achieve both a low profile and a large current when energized. [Means for solving the problem]

[0006] In order to solve the above problems, the conductive member with a refrigerant flow path is characterized in that the conductive member has a flat band-like appearance with a thickness dimension shorter than the width dimension and an internal flow path for flowing a refrigerant at least in the length direction, and is one of the divided shapes obtained by dividing the band member in the thickness direction including the internal flow path, and is made of a conductive metal and has one end connected to a component terminal of a specified electrical / electronic component and the other end connected to an electrical connection target of the electrical / electronic component to conduct electricity, a second part having the other of the divided shapes and combined with the first part to form the band member, and a pair of refrigerant inlets and outlets provided in the band member for flowing the refrigerant in the internal flow path of the band member formed by combining the first part and the second part. Effect of the Invention

[0007] According to the above-mentioned conductive member with a coolant passage, it is possible to achieve both a low profile and a large current when energized. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the conductive member with a coolant passage will be described. First, a first embodiment will be described.

[0010] Fig. 1 is a perspective view showing a conductive member with a coolant passage according to the first embodiment, and Fig. 2 is an exploded perspective view of the conductive member with a coolant passage shown in Fig. 1. In addition, Fig. 3 is a cross-sectional view taken along line V11-V11 in Fig. 1, and Fig. 4 is a cross-sectional view taken along line V12-V12 in Fig. 1.

[0011] The conductive member 1 with a coolant passage in this 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. The conductive member 1 with a coolant passage includes a pair of strip plate members 11 connected one-to-one to the pair of component terminals E11, a pair of coolant inlets and outlets 12 provided in each strip plate member 11, and a flat connection pipe 13 connecting the pair of strip plate members 11.

[0012] Each of the pair of strip members 11 has a flat strip-like appearance with a thickness dimension T11 shorter than a width dimension W11, and has an internal flow path 11a through which a refrigerant flows in the longitudinal direction D11, and is provided with a first part 111 and a second part 112.

[0013] The first component 111 is a component having one of the shapes of the divided shapes obtained by dividing the strip member 11 in the thickness direction D12 including the internal flow path 11a. In this embodiment, the first component 111 is a cover component that covers the groove opening 112a in the second component 112 as a groove component extending along the internal flow path 11a to form the internal flow path 11a. The first component 111 is formed of a conductive metal, and one end side is a component side connection piece 111a that is connected to a component terminal E11 of a predetermined electric / electronic component E1, and the other end side is an object side connection piece 111b that is connected to an electrical connection object. The first component 111 plays the role of a bus bar that connects the component terminal E11 of the electric / electronic component E1 to an electrical connection object.

[0014] The second part 112 is a member having the other shape of the divided shapes. In this embodiment, the second part 112 is a groove part whose groove opening 112a is covered by the first part 111 as a cover part. The second part 112 is combined with the first part 111 to form the strip plate member 11. The second part 112 is a flat rectangular groove part whose groove cross section is a flat rectangular shape, and the groove opening 112a is covered by the first part 111 to form the strip plate member 11 having a flat rectangular tube shape and an internal flow passage 11a whose flow passage cross section is a flat rectangular shape. In this embodiment, the second part 112 is also formed of a conductive metal like the first part 111.

[0015] Here, the component-side connection piece 111a and the target-side connection piece 111b of the first component 111 are rectangular pieces that protrude from the second component 112 in the longitudinal direction D11 of the strip member 11 and are connected to the component terminal E11 and the electrical connection target. The component-side connection piece 111a is fastened and fixed to the component terminal E11 via a screw E12, and a through-hole 111a-1 for the screw E12 is provided at approximately the center of the component-side connection piece 111a. The target-side connection piece 111b is similar, and a similar through-hole 111b-1 is provided at approximately the center.

[0016] In this embodiment, water, which is a conductive fluid, is used as the refrigerant flowing through the internal flow path 11a. In both the first component 111 and the second component 112, insulating coatings 111c-1 and 112b-1 are formed on the surface portions 111c and 112b constituting the inner surface of the internal flow path 11a as an insulating treatment for electrically insulating the refrigerant from the first component 111 and the second component 112. The first component 111 and the second component 112 are joined by forming a watertight joint 11b so that the refrigerant does not leak from the internal flow path 11a. The watertight joint 11b is formed by joining with an adhesive having watertight performance, or by brazing or welding the first component 111 and the second component 112 as metal members.

[0017] Next, a pair of refrigerant inlets 12 are provided in each strip member 11 to allow refrigerant to flow through internal flow path 11a. A component-side inlet 121 is provided near component-side connection piece 111a in first component 111, and a connection-side inlet 122 is provided near target-side connection piece 111b.

[0018] The component-side inlet / outlet 121 is a flow path opening that opens in the extension direction of the internal flow path 11a at the side of the component-side connecting piece 111a of the strip member 11, that is, at a position adjacent to one end side of the first component 111. Here, the internal flow path 11a extends while bending at a substantially right angle to the longitudinal direction D11 at a position adjacent to this one end side, and the component-side inlet / outlet 121 is a flow path opening that opens in the bending perpendicular extension direction D13. The component-side connecting piece 111a is a rectangular piece in which a part of the first component 111 protrudes in the longitudinal direction D11 from the edge of the second component 112 that constitutes this component-side inlet / outlet 121.

[0019] On the other hand, the connection side inlet / outlet 122 is a portion erected on the outer surface 111d of the first component 111, which is one of the front and back surfaces of the band plate member 11, at a position adjacent to the target side connection piece 111b side of the band plate member 11, that is, the other end side of the first component 111. At a position adjacent to this other end side, the internal flow path 11a extends at a substantially right angle to the length direction D11, but bent in the opposite direction to the right angle extending direction D13 of the component side inlet / outlet 121 described above. The connection side inlet / outlet 122 is erected on the outer surface 111d of this extending portion of the first component 111, and is a cylindrical protrusion communicating with the internal flow path 11a. The target side connection piece 111b is a rectangular piece in which a part of the first component 111 protrudes in the length direction D11 from the right angle extending portion of the second component 112 covered by the extending portion on which the connection side inlet / outlet 122 is erected.

[0020] The flat connection pipe 13 is a pipe that connects the component side inlets 121 of the pair of strip members 11 to connect the pair of internal flow paths 11a. This flat connection pipe 13 also has a flat appearance in which the pipe thickness dimension T12 is shorter than the pipe width dimension W12, similar to the strip members 11. On the other hand, the flat connection pipe 13 is formed of an insulating material so as not to electrically short the pair of strip members 11. In this embodiment, the flat connection pipe 13 is a U-shaped pipe that is connected to one of the component side inlets 121 and extends in the perpendicular extension direction D13, bends at right angles twice along the way, extends in the perpendicular extension direction D13, and is connected to the other component side inlet 121. Similarly to the band plate member 11, the flat connection pipe 13 is a flat rectangular tubular pipe with a flow passage cross section, and is composed of a pair of flat groove members 131 that divide the flat rectangular tubular pipe in two in the thickness direction D14. The flat connection pipe 13 is connected to each component side inlet / outlet 121 by sandwiching each component side inlet / outlet 121 in the thickness direction D14 at both ends of the pair of flat groove members 131. The connection here is made to form a watertight joint 13a so that the refrigerant does not leak from the connection with the component side inlet / outlet 121. The watertight joint 13a may be a joint between the pair of flat groove members 131 including the component side inlet / outlet 121 by an adhesive having watertight performance. Moreover, the watertight joint 13a may be a welded portion in which a pair of resin flat grooved members 131 are joined together, including the component side inlet / outlet 121, by partially heating and melting the resin flat grooved members 131.

[0021] According to the conductive member 1 with coolant flow passages of the first embodiment described above, a large current can be achieved by increasing only the width dimension of the first component 111 having a current-carrying function, that is, only the width dimension W11 of the strip member 11. On the other hand, since the thickness dimension T11 of the strip member 11 remains unchanged and is shorter than the width dimension W11, the conductive member 1 with coolant flow passages can be made low-profile. In this way, according to the conductive member 1 with coolant flow passages of this embodiment, it is possible to achieve both a low profile and a large current when electricity is applied.

[0022] In this embodiment, the second part 112 is a groove part, and the first part 111 is a cover part. With this configuration, the combination of the groove part and the cover part can effectively configure the flat cylindrical internal flow path 11a.

[0023] In this embodiment, one end of the first component 111 is a component-side connection piece 111a that protrudes from the second component 112, and the other end is a target-side connection piece 111b that protrudes from the second component 112. With this configuration, the component-side connection piece 111a and the target-side connection piece 111b, which are electrical connection parts and generate more heat when electricity is applied than other parts, are formed into a protruding shape, making it possible to form an internal flow path 11a up to the vicinity of them. In other words, with the above configuration, it is possible to efficiently cool the component-side connection piece 111a and the target-side connection piece 111b, which are expected to generate a lot of heat when electricity is applied.

[0024] In addition, the component side inlet / outlet 121 of the pair of refrigerant inlets / outlets 12 is a flow path opening that opens in the perpendicular extension direction D13 of the internal flow path 11a. On the other hand, the connection side inlet / outlet 122 of the pair of refrigerant inlets / outlets 12 is a cylindrical protrusion that is erected on one of the front and back surfaces of the strip member 11 and communicates with the internal flow path 11a. With this configuration, by making one of the pair of refrigerant inlets / outlets 12 a flow path opening of the flat-shaped internal flow path 11a, it is possible to easily connect the internal flow path 11a to another flow path having a similar flat shape. In addition, by making the other one a cylindrical protrusion that communicates with the internal flow path 11a, it is possible to connect to a flow path of another shape, such as a pipe shape, and the degree of freedom regarding the flow path connection can be improved.

[0025] In this embodiment, a pair of strip members 11 are provided so as to be connected one-to-one to a pair of component terminals E11 of the electric / electronic component E1, and the internal flow paths 11a of the pair of strip members 11 are connected by a flat connection pipe 13 made of an insulating material. With this configuration, the pair of strip members 11 connected to the electric / electronic component E1 can be efficiently cooled by one refrigerant flow path formed by connecting the pair of internal flow paths 11a via the flat connection pipe 13. In addition, since the connection of the internal flow paths 11a is performed by the flat connection pipe 13, the height of the flat connection pipe 13 as well can be reduced.

[0026] In this embodiment, an insulating treatment is applied to the surface portions 111c, 112b constituting the inner surface of the internal flow path 11a in both the first component 111 and the second component 112 of each strip member 11. This configuration makes it possible to effectively prevent a short circuit between a pair of component terminals E11 in the electric / electronic component E1, while allowing the use of water, which is a common conductive refrigerant.

[0027] Next, a second embodiment will be described. The second embodiment differs from the first embodiment in the division configuration of the band plate member. The following description of the second embodiment will focus on the differences from the first embodiment.

[0028] Fig. 5 is an exploded perspective view showing a conductive member with a coolant passage according to the second embodiment. In Fig. 5, components equivalent to those of the first embodiment shown in the exploded perspective view of Fig. 2 are denoted by the same reference numerals as in Fig. 2 only for components necessary for explanation, and duplicate explanations of those components will be omitted below.

[0029] In the conductive member 2 with a refrigerant passage of the second embodiment, the first part 211 and the second part 212 constituting the strip member 21 are a grooved part and the second part 212 is a cover part, which is the opposite of the first embodiment. The first part 211 as the grooved part is provided with a part-side connection piece 211a connected to the part terminal E11 of the electric / electronic part E1 by the screw E12 and a target-side connection piece 211b connected to the electrical connection target. On the other hand, the second part 212 as the cover part in this embodiment is in the shape of a cover obtained by removing the part-side connection piece 111a and the target-side connection piece 111b from the first part 111 in the first embodiment. In this embodiment, the conductive member 2 with a refrigerant passage is also constituted by connecting a pair of strip members 21 composed of the first part 211 and the second part 212 by the flat connection pipe 13 equivalent to that in the first embodiment.

[0030] It goes without saying that the electrically conductive member 2 with coolant passages of the second embodiment described above can also achieve both a low profile and a large current during energization, similar to the first embodiment described above.

[0031] Next, a third embodiment will be described. The third embodiment differs from the first embodiment in that the third embodiment has a configuration in which electric and electronic components are directly cooled. The following describes the third embodiment, focusing on the differences from the first embodiment.

[0032] Fig. 6 is a perspective view showing a conductive member with a coolant passage according to a third embodiment, and Fig. 7 is an exploded perspective view of the conductive member with a coolant passage shown in Fig. 6. Fig. 8 is a cross-sectional view taken along line V31-V31 in Fig. 1, and Fig. 9 is a cross-sectional view taken along line V32-V32 in Fig. 1. Fig. 10 is a partial plan view showing the peripheral structure of an electric / electronic component in the conductive member with a coolant passage shown in Fig. 6, as seen from the direction of arrow V33 in Fig. 6. In Figs. 6 to 10, the same reference numerals as in Figs. 1 to 4 are used for components equivalent to those in the first embodiment shown in Figs. 1 to 4, and only those components necessary for the explanation are given, and in the following, duplicate explanations of those components will be omitted.

[0033] First, in the conductive member 3 with a coolant passage of the third embodiment, a first component 311 as a groove component is provided with a component-side connection piece 311a and a target-side connection piece 311b, similar to the above-mentioned second embodiment. The component-side connection piece 311a is connected to a component terminal E31 of an electric / electronic component E3 by a screw E32, and the target-side connection piece 311b is connected to an electrical connection target of the electric / electronic component E3. On the other hand, the second component 312 is a simple cover member, similar to the second embodiment. In the first component 311 and the second component 312, the surface portions 311c and 312b constituting the inner surface of the internal passage 31a are subjected to the formation treatment of insulating coatings 311c-1 and 312b-1, similar to the first embodiment, as shown in FIG. 8. The first component 311 and the second component 312 are also joined watertightly, similar to the first embodiment.

[0034] Here, in this embodiment, the component terminals E31 of the electric / electronic component E3 are provided on a terminal surface E3a different from that of the first embodiment. The electric / electronic component E3 has a rectangular block-like appearance, and a pair of component terminals E31 are arranged in a terminal arrangement direction D15 along one side edge E3b on a terminal surface E3a, which is one of the six rectangular outer surfaces of the electric / electronic component E3, as in the first embodiment. On the other hand, the terminal surface E3a is a surface shifted by 90° from the surface on which the component terminals E31 are provided in the electric / electronic component E3 of the first embodiment. As a result, in this embodiment, a pair of strip members 31 are connected to the electric / electronic component E3 in a position shifted by 90° from that of the first embodiment. In the first components 311 of the pair of strip members 31, each component-side connection piece 311a is connected to the component terminal E31 so as to extend along the terminal arrangement direction D15 on the terminal surface E3a.

[0035] In this embodiment, among the pair of refrigerant inlets and outlets 32 in each band plate member 31, the connection side inlet and outlet 322 is the same as in the first embodiment except for the band plate member 31. On the other hand, the component side inlet and outlet 321 to which the flat connection pipe 13 is connected is a bent flow passage opening as follows. That is, the component side inlet and outlet 321 is a bent flow passage opening that is bent and extended in the orthogonal direction D16 relative to the front and back surfaces of the band plate member 31 and opens as an extension of the internal flow passage 31a. In order to form this bent flow passage opening, the adjacent portion of the component side connection piece 311a in the first component 311 is a bent groove that extends in the width direction D17 of the band plate member 31 and is bent and extended in the orthogonal direction D16 at the tip side. And the portion of the second component 312 as a cover component that closes the bent groove is also a bent cover having a shape corresponding to the bent groove. The bent groove of the first component 311 is covered with the bent cover of the second component 312, thereby forming the component side inlet and outlet 321 as the bent flow passage opening. A pair of internal flow paths 31a are connected by connecting the component side inlets 321 of the pair of band plate members 31 with the flat connection pipe 13 similar to that of the first embodiment. The connection of the flat connection pipe 13 to the component side inlets 321 as the bent flow path openings is performed by clamping with a pair of flat groove members 131 similar to that of the first embodiment and forming a watertight joint 13a, as shown in Fig. 9.

[0036] The flat connection pipe 13 is positioned at a surface mounting position P31 with respect to the terminal surface E3a of the electric / electronic component E31 and the adjacent outer surface E3c adjacent thereto at one side edge E3b along the terminal arrangement direction D15 by connecting the component side inlet / outlet 321 as a bent flow path opening. In this embodiment, the flat connection pipe 13 positioned at this surface mounting position P31 is surface mounted to the adjacent outer surface E3c at one surface 132 of its front and back surfaces. Furthermore, the surface mounting here is performed via a heat transfer material 133 such as silicone grease as shown in FIG.

[0037] It goes without saying that the conductive member 3 with coolant passages of the third embodiment described above can also achieve both a low profile and a large current during energization, similar to the first embodiment described above.

[0038] In this embodiment, the flat connection pipe 13 is disposed so that one of the front and back surfaces 132 is in contact with the outer surface of the electric / electronic component E31. With this configuration, even if the electric / electronic component E3 itself generates heat, the heat can be effectively transferred to the internal refrigerant via the flat connection pipe 13 that is in contact with the outer surface, thereby cooling the electric / electronic component E3.

[0039] In addition, in this embodiment, the flat connection pipe 13 is surface-attached to the electric / electronic component E3 via a predetermined heat transfer material 133. According to this configuration, the heat of the electric / electronic component E3 can be more effectively transferred to the flat connection pipe 13 via the heat transfer material 133.

[0040] In this embodiment, component terminals E31 are arranged in a terminal arrangement direction D15 on a terminal surface E3a, which is one rectangular outer surface of the rectangular block-shaped electric / electronic component E3. The flat connection pipe 13 is surface-attached to an adjacent outer surface E3c adjacent to the terminal surface E3a. A pair of component-side inlets 321 connected by the flat connection pipe 13 are bent flow passage openings that position the flat connection pipe 13 at a surface-attachment position P31 relative to the adjacent outer surface E3c. With this configuration, by surface-attaching the adjacent outer surface E3c relative to the terminal surface E3a of the electric / electronic component E3 and the flat connection pipe 13, heat from the electric / electronic component E3 can be transferred to the flat connection pipe 13 while keeping the whole compact.

[0041] Next, a fourth embodiment will be described. The fourth embodiment differs from the first embodiment in the second member constituting the band plate member and the connection structure of the pair of internal flow paths. The following description of the fourth embodiment will focus on the differences from the first embodiment.

[0042] FIG. 11 is a perspective view showing a conductive member with a coolant passage according to the fourth embodiment, and FIG. 12 is an exploded perspective view of the conductive member with a coolant passage shown in FIG. 11. FIG. 13 is a plan view of the conductive member with a coolant passage shown in FIG. 11, with electric and electronic components removed, as viewed from the direction of arrow V41 in FIG. 11. FIG. 14 is a cross-sectional view taken along line V42-V42 in FIG. 11, and FIG. 15 is a view showing how a pair of internal passages are connected in the conductive member with a coolant passage shown in FIG. 11, as viewed from the direction of arrow V43 in FIG. 11. FIG. 16 is a cross-sectional view taken along line V44-V44 in FIG. 13. In FIG. 11 to FIG. 16, the same reference numerals as in FIG. 1 to FIG. 4 are used for components equivalent to those of the first embodiment shown in FIG. 1 to FIG. 4, and only those components necessary for the description will be described below.

[0043] In the conductive member 4 with a refrigerant passage of the fourth embodiment, a second part 412 constituting the strip member 41 is an outer wall part constituting a part of the outer wall B11 of the device housing B1 made of an insulating material. The second part 412 is a groove part in which a flow groove 412a constituting a part of the internal flow path 41a is formed on one of the front and back surfaces of the outer wall part. The second part 412 is combined one-to-one with the first part 111 which is a cover part similar to that of the first embodiment to constitute the strip member 41. The second part 412 as the outer wall part in which the flow groove 412a is formed is provided in a pair such that each flow groove 412a extends along the terminal arrangement direction D15 of a pair of component terminals E11 of the electric / electronic component E1.

[0044] Here, the second component 412, which is an outer wall part made of insulating resin, and the first component 111, which is made of conductive metal and plays the role of a bus bar, are joined by forming a watertight joint 41b so that the refrigerant does not leak from the internal flow path 41a, as shown in FIG. 14. The watertight joint 41b is formed by joining with a watertight adhesive, or by welding in which the second component 412 is partially heated and melted while being joined to the first component 111. Also in this embodiment, water, which is a fluid having electrical conductivity, is used as the refrigerant flowing through the internal flow path 41a. For this reason, an insulating coating 111c-1 is formed on a surface portion 111c constituting the inner surface of the internal flow path 41a in the first component 111 as an insulating treatment.

[0045] In this embodiment, the pair of refrigerant inlets and outlets 42 on the side of the target-side connection piece 111b in the first component 111 is the connection-side inlet and outlet 122 similar to the first embodiment. On the other hand, the component-side inlet and outlet 421 of the pair of refrigerant inlets and outlets 42 is provided in the flow passage groove 412a of the second component 412 at a position adjacent to the component-side connection piece 111a, which is the connection end portion fastened and fixed to the component terminal E11 by the screw E12, and is a through hole penetrating the outer wall portion.

[0046] As a connection structure of a pair of internal flow paths 41a in which a pair of flow grooves 412a are covered one-to-one with the first component 111, a through hole connection groove 43 shown in FIG. 15 and FIG. 16 and a groove cover 44 shown in FIG. 12 and FIG. 16 are provided. Here, an access opening B12 is provided between the pair of second components 412 for connecting the component-side connection piece 111a of the first component 111 to the component terminal E11 with the screw E12 from the other surface side opposite to the flow groove 412a. The component-side entrance / exit 421 is provided at a position adjacent to the inner periphery B12a of the access opening B12. The component-side entrance / exit 421 is provided at two adjacent positions aligned in the terminal arrangement direction D15 around the inner periphery B12a according to the pair of flow grooves 412a extending along the terminal arrangement direction D15. As indicated by arrow D18, the through hole connecting groove 43 is formed so as to extend from one component side entrance 421, branch out into two, along the inner peripheral edge B12a of the access opening B12, and join at the other component side entrance 421. The groove cover 44 is a resin ring plate formed so as to cover the pair of component side entrances 421 and the pair of through hole connecting grooves 43 extending along the inner peripheral edge B12a of the access opening B12.

[0047] As shown in Fig. 16, the groove cover 44 is formed by forming a watertight joint 44a on the outer wall portion of the second part 412 so that the refrigerant does not leak from the internal flow path 41a. The watertight joint 44a is formed by bonding with a watertight adhesive or by welding the second part 412 and the groove cover 44 while partially heating and melting them. As shown in Figs. 12 and 16, the groove cover 44 is configured so that a part of it enters the inside of the access opening B12. A ring-shaped packing 45 is disposed between the cover-side entry part 441 and the inner periphery B12a of the access opening B12, so that further watertightness is achieved so that the refrigerant does not leak from the internal flow path 41a to the inside of the access opening B12.

[0048] It goes without saying that the conductive member 4 with coolant passages of the fourth embodiment described above can also achieve both a low profile and a large current during energization, similar to the first embodiment described above.

[0049] In this embodiment, the second component 412 is an outer wall portion in which a flow path groove 412a is formed in a part of the outer wall B11 of the device housing B1. In addition, the component side inlet / outlet 421 of the pair of refrigerant inlets / outlets 42 is a through hole provided at a position adjacent to the component side connection piece 111a in the flow path groove 412a. In addition, a through hole connecting groove 43 connecting the pair of component side inlets / outlets 421 is formed on the surface of the outer wall B11 opposite to the flow path groove 412a. A groove cover 44 is provided to cover the groove opening of the through hole connecting groove 43 and thereby form a connecting flow path that connects the pair of internal flow paths 41a.

[0050] According to this configuration, since the second component 412 is an outer wall portion of the outer wall B11 of the device housing B1, the additional dimension in the thickness direction D12 on the flow path groove 412a side is only the thickness of the first component 111, and further reduction in height can be achieved. Also, the connection flow path connecting the pair of internal flow paths 41a is composed of a pair of component side inlets 421, each of which is a through hole, and the through hole connecting groove 43 and groove cover 44 connecting them. For this connection flow path as well, the additional dimension in the thickness direction D12 is only the thickness of the groove cover 44, and further reduction in height can be achieved in this respect as well.

[0051] In addition, in this embodiment, an access opening B12 is provided between the pair of second components 412. The pair of component-side inlets 421 are provided at a pair of adjacent positions with respect to the inner periphery B12a of the access opening B12. The through-hole connecting groove 43 is formed so as to extend in two branches along the inner periphery B12a at one component-side inlet 421 and join at the other component-side inlet 421. According to this configuration, by providing the access opening B12, it is possible to improve the workability of connecting the first component 111 and the component terminal E11 of the electric / electronic component E1. In addition, by arranging the component-side inlets 421 and the through-hole connecting groove 43 that constitute the connecting flow path that connects the internal flow paths 41a so as to surround the access opening B12, it is possible to provide the connecting flow paths compactly together around the access opening B12. Furthermore, by forming the through hole connecting groove 43 to be bifurcated along the inner peripheral edge B12a of the access opening B12, the connecting flow paths can be made compact while providing a sufficiently large flow path cross-sectional area for the connecting flow paths.

[0052] Next, a fifth embodiment will be described. The fifth embodiment differs from the first embodiment in the configuration of the internal flow path in the band plate member and the refrigerant inlet and outlet. The fifth embodiment will be described below, focusing on the differences from the first embodiment.

[0053] Fig. 17 is a perspective view showing a conductive member with a coolant passage according to a fifth embodiment, and Fig. 18 is a cross-sectional view taken along line V51-V51 in Fig. 17. Fig. 19 is a top view showing one strip member shown in Fig. 17 together with an internal passage and an electric / electronic component as viewed from the direction of arrow V52 in Fig. 17. Fig. 20 is a bottom view showing a connection between one strip member and an electric / electronic component as viewed from the direction of arrow V53 in Fig. 17 together with an internal passage and an electric / electronic component. In Figs. 17 to 20, components equivalent to those of the first embodiment shown in Figs. 1 to 4 are denoted by the same reference numerals as in Figs. 1 to 4 only for those components necessary for the explanation, and in the following, duplicate explanations of those components will be omitted.

[0054] In the conductive member 5 with coolant passage of the fifth embodiment, one end of each strip plate member 51 is connected to a component terminal E11 of an electric / electronic component E1, and the other end is connected to an electrical connection target. Each end is fastened to the other by a screw. The strip plate member 51 is composed of a first part 511 and a second part 512 made of conductive metal and having a rectangular plate shape that is mirror symmetrical to each other.

[0055] The first component 511 has a first component-side screw through hole 511a at one end through which a screw E12 for screwing the component terminal E11 passes, and a similar first target-side screw through hole 511b at the other end for screwing the electrical connection target. A first flow passage groove 511c constituting a part of the internal flow passage 51a is formed on one of the front and back surfaces of the first component 511. The first flow passage groove 511c passes between the first component-side screw through hole 511a and the end face 511d on the component terminal E11 side and a pair of side faces 511e along the length direction D11 on the component terminal E11 side, and forms a U-shaped groove surrounding the periphery of the first component-side screw through hole 511a.

[0056] The second component 512 has a mirror-symmetrical shape to the first component 511, and is assembled so as to be superimposed on the surface of the first component 511 on which the first flow passage groove 511c is formed to form the strip member 51. The second component 512 is formed with second component-side screw through holes 512a and second target-side screw through holes 512b which are in one-to-one communication with the first component-side screw through holes 511a and the first target-side screw through holes 511b. In addition, a second flow passage groove 512c which is superimposed on the first flow passage groove 511c to form the internal flow passage 51a is formed on the surface facing the surface on which the first flow passage groove 511c is formed.

[0057] The first component 511 and the second component 512 are joined by overlapping the forming surface of the first flow channel 511c and the forming surface of the second flow channel 512c, and forming a watertight joint 51b at the boundary between the two so that the refrigerant does not leak from the internal flow channel 51a. The watertight joint 51b is formed by joining with an adhesive having watertight performance. Also in this embodiment, water, which is a fluid having electrical conductivity, is used as the refrigerant. For this reason, an insulating treatment is applied to the inner surface of the first flow channel 511c to form an insulating coating 511c-1 that electrically insulates the refrigerant from the first component 511. Also, an insulating treatment is applied to the inner surface of the second flow channel 512c to form a similar insulating coating 512c-1.

[0058] In this embodiment, the internal flow passage 51a thus formed opens on each of a pair of band side surfaces 51d along the length direction D11 of the band plate member 51, and extends between the pair of band side surfaces 51d while bending in a U-shape as described above. The opening positions of the pair of band side surfaces 51d of this internal flow passage 51a are coaxial with each other in the width direction D17 of the band plate member 51 near the first target side screw through hole 511b and the second target side screw through hole 512b. In addition, a pair of refrigerant inlets and outlets 52 are attached to the openings of the internal flow passage 51a on each band side surface 51d, and serve as nipple members 521 for connecting a predetermined pipe to the internal flow passage 51a.

[0059] It goes without saying that the electrically conductive member 5 with coolant passages according to the fifth embodiment described above can also achieve both a low profile and a large current during energization, similar to the first embodiment described above.

[0060] In this embodiment, the first component 511 has a first flow groove 511c that passes between the pair of side surfaces 511e and surrounds the first component side screw through hole 511a in a U-shape, and the second component 512 has a similar second flow groove 512c. With this configuration, the first component 511 and the second component 512, which are two mirror-symmetric plate members, are stacked together, so that the strip plate member 51, that is, the conductive member 5 with a coolant flow path, can be made even lower in height. In addition, the internal flow path 51a is configured to surround the first component side screw through hole 511a and the second screw through hole 512a used for connection to the component terminal E11 in a U-shape, so that the connection portion around the screw, which tends to generate a large amount of heat when current is applied, can be effectively cooled.

[0061] In this embodiment, the refrigerant is water, i.e., a fluid having electrical conductivity, and the inner surface of the first flow passage groove 511c is insulated, and the inner surface of the second flow passage groove 512c is similarly insulated. With this configuration, by forming both the first component 511 and the second component 512 from a conductive metal, the electrical resistance of the conductive member 5 with a refrigerant flow passage can be reduced. Furthermore, by insulating the inner surface of the first flow passage groove 511c and the inner surface of the second flow passage groove 512c, the refrigerant can be electrically isolated from the current passing through the conductive member 5 with a refrigerant flow passage, and a general refrigerant such as water can be used.

[0062] In this embodiment, the internal flow passage 51a opens on each of a pair of band side surfaces 51d of the band plate member 51, and extends from one of the pair of band side surfaces 51d to the other while bending in a U-shape midway. A pair of refrigerant inlets and outlets 52 are nipple members 521 attached to the respective openings of the internal flow passage 51a. With this configuration, the nipple members 521 are attached to the openings of the internal flow passage 51a on each of the pair of band side surfaces 51d of the band plate member 51, so that the height of the connection to other piping can also be reduced.

[0063] Next, a sixth embodiment will be described. The sixth embodiment is a modified example of the fifth embodiment, and differs from the fifth embodiment in the shape of the internal flow path and the associated position of the refrigerant inlet and outlet. The sixth embodiment will be described below, focusing on the differences from the fifth embodiment.

[0064] Fig. 21 is a top view similar to Fig. 19 relating to the fifth embodiment, showing a conductive member with a coolant flow path according to the sixth embodiment. In Fig. 21, components equivalent to those in the fifth embodiment shown in Figs. 17 to 20 are denoted by the same reference numerals as in Figs. 17 to 20 only for components necessary for the explanation, and duplicate explanations of those components will be omitted below.

[0065] In the conductive member 6 with refrigerant passage of the sixth embodiment, the internal passage 61a of the band plate member 61 is formed in a U-shape surrounding the first component side screw through hole 611a of the first member 611 and the second component side screw through hole 612a of the second member 612, which is the same as the fifth embodiment. However, in this embodiment, the opening position of the internal passage 61a on a pair of band side surfaces 61d is different from that of the fifth embodiment. That is, the opening position of one band side surface 61d is approximately at the center position in the length direction D11, while the opening position of the other band side surface 61d is biased toward the end surface 611d on the component terminal E11 side of the electric / electronic component E1. Then, the nipple members 521 similar to those of the fifth embodiment are attached to the openings at different positions as a pair of refrigerant inlets and outlets 52.

[0066] It goes without saying that the conductive member 5 with refrigerant flow path of the sixth embodiment described above can achieve the same effect as the fifth embodiment, namely, the same effect as the first embodiment described above of achieving both a low profile and a large current when energized.

[0067] In the fifth and sixth embodiments described above, the conductive members 5, 6 with refrigerant flow paths are exemplified, in which the nipple members 521 as the refrigerant inlet / outlet 52 are attached at different positions on the band side surfaces 51d, 61d of the band plate members 51, 61. In this manner, in the fifth and sixth embodiments, the refrigerant inlet / outlet can be set at any position during design.

[0068] Next, a seventh embodiment will be described. The seventh embodiment is a modified example of the fifth embodiment described above, and differs from the fifth embodiment in that a plurality of conductive members with coolant flow paths are connected in the width direction. The seventh embodiment will be described below, focusing on the differences from the fifth embodiment.

[0069] Fig. 22 is a perspective view showing a conductive member with a refrigerant passage according to the seventh embodiment, and Fig. 23 is a plan view of the conductive member with a refrigerant passage shown in Fig. 22, as seen from the direction of arrow V71 in Fig. 22. Note that in Figs. 22 and 23, for components equivalent to those of the fifth embodiment shown in Figs. 17 to 20, only those components necessary for explanation are given the same reference numerals as in Figs. 17 to 20, and duplicate explanations of those components will be omitted below.

[0070] The conductive member 7 with a refrigerant passage of the seventh embodiment has the same configuration as the conductive member 5 with a refrigerant passage of the fifth embodiment. However, in this embodiment, a plurality of electric / electronic components E1 to be connected (two in the illustrated example) are linearly arranged in the width direction D17 of the strip member 51 connected to the component terminal E11. The nipple members 521 of the refrigerant inlet / outlet 52 of one of a pair of strip members 51 corresponding to a pair of adjacent electric / electronic components E1 and the nipple members 521 of the refrigerant inlet / outlet 52 of the other are linearly arranged in the width direction D17. The nipple members 521 arranged in this manner are connected by a straight pipe 71 extending in the width direction D17. A retaining portion 521a is formed at the tip of each nipple member 521, which enters the inside of the straight pipe 71 and engages with the inner surface of the pipe from the inside. As described in the fifth embodiment, the nipple members 521 of the pair of refrigerant inlets and outlets 52 in one band plate member 51 are positioned coaxially in the width direction D17 of the band plate member 51 near the first target side screw through hole 511b and the second target side screw through hole 512b. For this reason, in this embodiment, the same band plate members 51, that is, the same conductive members 5 with refrigerant flow paths, can be simply arranged in two in the width direction D17 to connect adjacent nipple members 521 with the straight piping 71. As a result, the internal flow paths 51a of adjacent band plate members 51 are connected with each other by the straight piping 71.

[0071] It goes without saying that the conductive member 7 with coolant passages of the seventh embodiment described above can also achieve both a low profile and a large current during energization, similar to the fifth embodiment described above.

[0072] In this embodiment, the refrigerant inlet / outlet 52 of one of a pair of adjacent band plate members 51 and the refrigerant inlet / outlet 52 of the other are aligned in a straight line in the width direction D17 and connected by a straight pipe 71 extending in the width direction D17. With this configuration, the internal flow paths 51a of the multiple conductive members 7 with refrigerant flow paths are connected by the straight pipe 71, so that the overall configuration of the refrigerant flow paths for cooling the electrical connections of the multiple electric and electronic components E1 can be simplified. This simplification allows for a reduction in space and weight of the overall configuration for cooling the electrical connections of the multiple electric and electronic components E1.

[0073] Next, an eighth embodiment will be described. The eighth embodiment is a modified example of the seventh embodiment described above, and the connection position of the straight pipe is different from that of the seventh embodiment. The following describes the eighth embodiment, focusing on the differences from the seventh embodiment.

[0074] Fig. 24 is a plan view of an electrically conductive member with a coolant passage according to an eighth embodiment, showing only a pair of adjacent band plate members connected by one straight pipe, similar to Fig. 23. Note that in Fig. 24, for components equivalent to those of the seventh embodiment shown in Figs. 22 and 23, only those components necessary for the explanation are given the same reference numerals as in Figs. 22 and 23, and hereinafter, redundant explanations of those components will be omitted.

[0075] In the conductive member 8 with refrigerant flow passages of the eighth embodiment, the opening position of the internal flow passage 81a of the strip member 81 is slightly closer to the component terminal E11 of the electric / electronic component E1 than in the seventh embodiment. The nipple member 521 forming the refrigerant inlet / outlet 52 is attached to this position closer to the component terminal E11, and the adjacent nipple members 521 are connected to each other by the straight pipe 71 at the position closer to the component terminal E11, so that the internal flow passages 81a are connected to each other. In this embodiment, the opening positions of the internal flow passages 81a in each strip member 81, that is, the attachment positions of the nipple members 521, are aligned coaxially in the width direction D17. By utilizing this arrangement, the adjacent nipple members 521 can be connected to each other by the straight pipe 71 simply by arranging two identical conductive members 8 with refrigerant flow passages in the width direction D17.

[0076] It goes without saying that the conductive member 8 with coolant passages according to the eighth embodiment described above can also achieve both a low profile and a large current during energization, similar to the seventh embodiment described above.

[0077] Next, a ninth embodiment will be described. The ninth embodiment is a further modified example of the seventh embodiment described above, and the connection position of the straight pipe is different from both the seventh and eighth embodiments. The following describes the ninth embodiment, focusing on the differences from the seventh and eighth embodiments.

[0078] Fig. 25 is a plan view of a conductive member with a coolant passage according to the ninth embodiment, equivalent to Fig. 23. In Fig. 25, components equivalent to those of the seventh embodiment shown in Figs. 22 and 23 are denoted by the same reference numerals as in Figs. 22 and 23 only for components necessary for the explanation, and duplicate explanations of those components will be omitted below.

[0079] In the conductive member 9 with refrigerant flow passage of the ninth embodiment, the opening positions of the internal flow passages 91a in the band plate member 91, i.e., the nipple members 521 of the refrigerant inlet / outlet 52, are not aligned coaxially in the width direction D17. One of the pair of nipple members 521 is provided closer to the component terminal E11 of the electric / electronic component E11 than the center in the length direction D11, and the other is provided closer to the first target-side screw through hole 511b and the second target-side screw through hole 512b. The internal flow passage 91a connects the nipple members 521 thus positioned in the length direction D11 in a bent shape that surrounds the first component-side screw through hole 511a and the second component-side screw through hole 512a in a U-shaped manner.

[0080] Here, in this embodiment, the attachment positions of the nipple members 521 in the strip member 91 are shifted in the length direction D11. Due to this shift, even if two conductive members 9 with refrigerant passages are simply arranged in the width direction D17, the nipple members 521 of the refrigerant inlet / outlet 52 cannot be connected to each other with the straight pipe 71. For this reason, in this embodiment, the following configuration is adopted so that the nipple member 521 of one refrigerant inlet / outlet 52 and the nipple member 521 of the other refrigerant inlet / outlet 52 are arranged in a straight line in the width direction D17 and can be connected to each other with the straight pipe 71. That is, in this embodiment, between two adjacent conductive members 9 with refrigerant passages, one strip member 91 is connected to the component terminal E11 of each electric / electronic member E1 in an inverted state in which the other strip member 91 is reversed.

[0081] It goes without saying that the conductive member 9 with coolant passages of the ninth embodiment described above can also achieve both a low profile and a large current during energization, similar to the seventh embodiment described above.

[0082] Moreover, in the seventh to ninth embodiments described above, conductive members with refrigerant flow paths 7 to 9 are exemplified in which the relative positions in the longitudinal direction D11 of a pair of refrigerant inlets and outlets 52 in one strip member 51, 81, 91 are different. In this manner, in the seventh to ninth embodiments, the refrigerant inlets and outlets can be set at any positions during design. However, as explained in the ninth embodiment, when the pair of refrigerant inlets and outlets 52 are set at positions offset in the longitudinal direction D11, one of a pair of adjacent strip members 91 can be inverted relative to the other to enable connection by a straight pipe 71.

[0083] The first to ninth embodiments described above are merely representative forms of the conductive member with a coolant passage. The conductive member with a coolant passage is not limited to these, and can be modified in various ways.

[0084] For example, in the above-described embodiment, as an example of the conductive member with a coolant passage, conductive members 1,...,9 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 exemplified. However, the conductive member with a coolant passage 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.

[0085] In the above-described embodiment, as an example of the conductive member with a coolant flow passage, a liquid-cooled conductive member with a coolant flow passage 1,...,9 in which water, which is a conductive liquid, flows as a coolant through the internal flow passage 11a,...,91a is exemplified. However, the conductive member with a coolant flow passage is not limited to this, and the coolant may be a non-conductive liquid or an air-cooling gas. When a non-conductive liquid or an air-cooling gas is used as the coolant, insulation treatment is not required on the inner surface of the internal flow passage on the side of the first component made of conductive metal.

[0086] In the above-described embodiment, the conductive member with refrigerant passage 1,...,9 including a pair of strip plate members 11,...,91 is illustrated as an example of the conductive member with refrigerant passage. However, the conductive member with refrigerant passage is not limited to this, and may include only one strip plate member, or three or more strip plate members. When only one strip plate member is included, the strip plate member functions as the conductive member with refrigerant passage itself.

[0087] In the above-mentioned first to fourth embodiments, the conductive members 1,...,4 in which the internal channels 11a,...,41a of a pair of strip members 11,...,41 are connected by the flat connecting pipes 13 or the through-hole connecting grooves 43 are exemplified as an example of the conductive member with a refrigerant channel. However, the conductive member with a refrigerant channel is not limited thereto. For example, as exemplified in the fifth to ninth embodiments, a conductive member with a refrigerant channel may be provided with a pair of strip members 51,...,91, but the two strip members may not be connected to each other. In the seventh to ninth embodiments among these examples, each strip member 51,...,91 is connected to the strip member 51,...,91 of another conductive member with a refrigerant channel 7,...,9 via a straight pipe 71. In this way, each of the pair of unconnected strip members 51, 81, 91 in one conductive member with a coolant passage 5,..., 9 can be said to function as an independent conductive member with a coolant passage by itself.

[0088] In the above-mentioned first to third and fifth to ninth embodiments, the strip members 11,...,31,51,81,91 in which the first component 111,...311,511 and the second component 112,...312,512 are both made of conductive metal are exemplified as an example of the strip member. In the above-mentioned fourth embodiment, the strip member 41 in which the first component 111 is made of conductive metal and the second component 412 is made of insulating material and serves as an outer wall portion constituting a part of the outer wall B11 of the device housing B1 is exemplified as an example of the strip member. However, the strip member is not limited to these, and as long as the first component that is responsible for the electrical connection of the electric and electronic components is made of conductive metal, the second component may be made of insulating material regardless of its shape, etc. [Explanation of symbols]
