Summary of the Invention
Problems to be Solved by the Invention
[0004] Here, the conductive member with a refrigerant flow path using the above-described conductive pipe is disadvantageous in terms of low-profile design because its thickness dimension is determined by the pipe diameter. Further, when the current flowing during energization increases, it is necessary to increase the pipe diameter, making it even more difficult to achieve a low-profile design.
[0005] Therefore, the present invention focuses on the above problems and aims to provide a conductive member with a refrigerant flow path that can achieve both low-profile design and large current during energization.
Means for Solving the Problems
[0006] In order to solve the above problems, the conductive member with a refrigerant flow path has a flat strip-like appearance with a thickness dimension shorter than the width dimension, and an internal flow path for flowing the refrigerant at least in its length direction. It has one of the split shapes obtained by splitting the strip member in the thickness direction including the internal flow path, is formed of a conductive metal, has one end side connected to a component terminal of a predetermined electrical and electronic component, and the other end side connected to an electrical connection target of the electrical and electronic component to conduct electricity. It includes a first component, a second component having the other of the split shapes and combined with the first component to form the strip member, and a pair of refrigerant inlets and outlets provided on the strip member for flowing the refrigerant through the internal flow path of the strip member formed by combining the first component and the second component.

[0009] Hereinafter, an embodiment of the conductive member with a refrigerant flow path will be described. First, the first embodiment will be described.
[0010] FIG. 1 is a perspective view showing a conductive member with a refrigerant flow path according to the first embodiment, and FIG. 2 is an exploded perspective view of the conductive member with a refrigerant flow path shown in FIG. 1. Further, 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 refrigerant flow path in the present embodiment is a member for connecting each of a pair of component terminals E11 in a relay which is an electric and electronic component E1 to an electrical connection target of the electric and electronic component E1. The conductive member 1 with a refrigerant flow path includes a pair of strip members 11 connected one-to-one to the pair of component terminals E11, refrigerant inlets and outlets 12 provided in pairs on each strip member 11, and a flat connection pipe 13 connecting the pair of strip members 11.
[0012] Each of the pair of strip members 11 is a member having a flat strip-like appearance in which the thickness dimension T11 is shorter than the width dimension W11, and an internal flow path 11a for flowing refrigerant in the length direction D11 thereof, and includes a first component 111 and a second component 112.
[0013] The first component 111 is a member having one of the divided shapes obtained by dividing the strip member 11 in the thickness direction D12 including the internal flow path 11a. In the present embodiment, the first component 111 serves as 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. Further, this first component 111 is formed of a conductive metal, and one end side serves as a component side connection piece 111a connected to the component terminal E11 of a predetermined electrical and electronic component E1, and the other end side serves as a target side connection piece 111b connected to an electrical connection target. The first component 111 serves as a bus bar that connects the component terminal E11 of the electrical and electronic component E1 and the electrical connection target.
[0014] The second component 112 is a member having the other of the above-described divided shapes. In the present embodiment, the second component 112 serves as a groove component in which the groove opening 112a is covered by the first component 111 as a cover component. The second component 112 is combined with the first component 111 to form the strip member 11. This second component 112 is a flat angle groove component having a flat rectangular groove cross section, and when the groove opening 112a is covered by the first component 111, a flat angle cylindrical strip member 11 having an internal flow path 11a with a flat rectangular flow path cross section is formed. Further, in the present embodiment, the second component 112 is also formed of a conductive metal, similar to the first component 111.
[0015] Here, the component side connection piece 111a and the target side connection piece 111b in the first component 111 are rectangular pieces that project from the second component 112 in the length direction D11 of the strip member 11 and are connected to the component terminal E11 and the electrical connection target. Further, 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 substantially at the center of the component side connection piece 111a. The same applies to the target side connection piece 111b, and a similar through hole 111b-1 is provided substantially at the center thereof.
[0016] Further, in the present embodiment, water, which is a fluid having conductivity, is used as the refrigerant flowing through the internal flow path 11a. Then, as an insulation treatment for electrically insulating the refrigerant from the first component 111 and the second component 112 on the surface portions 111c and 112b that constitute the inner surface of the internal flow path 11a in both the first component 111 and the second component 112, a formation treatment of the insulating films 111c-1 and 112b-1 is performed. Also, the joining of the first component 111 and the second component 112 is performed by forming a watertight joint portion 11b so that the refrigerant does not leak from the internal flow path 11a. The watertight joint portion 11b is formed by joining with an adhesive having watertight performance, brazing, welding, etc. of the first component 111 and the second component 112 as metal members.
[0017] Next, the refrigerant inlets and outlets 12 provided in pairs on each strip member 11 are portions provided for flowing the refrigerant through the internal flow path 11a. A component-side inlet / outlet 121 is provided near the component-side connection piece 111a in the first component 111, and a connection-side inlet / outlet 122 is provided near the target-side connection piece 111b.
[0018] The component-side inlet / outlet 121 is a flow path opening that opens in the extending direction of the internal flow path 11a at an adjacent position on the component-side connection piece 111a side in the strip member 11, that is, on one end side of the first component 111. Here, the internal flow path 11a extends while being bent substantially at a right angle with respect to the length direction D11 at an adjacent position to this one end side, and the component-side inlet / outlet 121 is a flow path opening that opens in the bent right-angle extending direction D13. The component-side connection piece 111a is a rectangular piece in which a part of the first component 111 projects in the length 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 entrance / exit 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 strip member 11, at an adjacent position to the target-side connection piece 111b side in the strip member 11, that is, the other end side of the first component 111. The internal flow path 11a extends in a direction substantially perpendicular to the length direction D11 at an adjacent position to this other end side, but bends and extends in a direction opposite to the right-angle extension direction D13 of the component-side entrance / exit 121 described above. The connection-side entrance / exit 122 is a cylindrical protrusion erected on the outer surface 111d of this extended portion of the first component 111 and 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 a right-angle extended portion of the second component 112 covered by the extended portion where the connection-side entrance / exit 122 is erected.
[0020] The flat connecting pipe 13 connects the component-side entrances and exits 121 in the pair of strip members 11 to connect the pair of internal flow paths 11a. Similar to the strip member 11, the flat connecting pipe 13 has a flat appearance with a pipe thickness dimension T12 shorter than the pipe width dimension W12. On the other hand, the flat connecting pipe 13 is formed of an insulating material so as not to electrically short-circuit the pair of strip members 11. In the present embodiment, the flat connecting pipe 13 is connected to one component-side entrance and exit 121 and extends in the right-angle extending direction D13. It bends at a right angle twice in the middle and extends in the right-angle extending direction D13 and is connected to the other component-side entrance and exit 121, forming a U-shaped pipe. Also, similar to the strip member 11, the flat connecting pipe 13 is a flat rectangular pipe with a flat rectangular cross-section of the flow path. The flat connecting pipe 13 is composed of a pair of flat groove members 131 obtained by dividing the flat rectangular pipe in its thickness direction D14. The flat connecting pipe 13 is connected to each component-side entrance and exit 121 by sandwiching each component-side entrance and exit 121 in the thickness direction D14 at both ends of the pair of flat groove members 131. The connection here is made so as to form a watertight joint 13a so that refrigerant does not leak from the connection part with the component-side entrance and exit 121. Examples of the watertight joint 13a include a joint between a pair of flat groove members 131 including the component-side entrance and exit 121 by an adhesive having watertight performance. Also, examples of the watertight joint 13a include a welded part where a pair of flat groove members 131 including the component-side entrance and exit 121 are joined while partially heating and melting the resin-made flat groove members 131.
[0021] According to the conductive member 1 with a refrigerant flow path of the first embodiment described above, it is possible to increase the current by expanding only the width dimension of the first component 111 having an energization 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 a refrigerant flow path can be made low-profile. Thus, according to the conductive member 1 with a refrigerant flow path of the present embodiment, it is possible to achieve both low-profile and increased current during energization.
[0022] Here, in the present embodiment, the second component 112 is a groove component, and the first component 111 is a cover component. According to this configuration, a flat cylindrical internal flow path 11a can be effectively configured by combining the groove component and the cover component.
[0023] Also, in the present embodiment, one end side of the first component 111 is a component-side connection piece 111a that protrudes from the second component 112, and the other end side is a target-side connection piece 111b that protrudes from the second component 112. According to this configuration, by making the component-side connection piece 111a and the target-side connection piece 111b, which are electrical connection parts and generate more heat during energization than other parts, in an overhanging shape, it becomes possible to form the internal flow path 11a up to their vicinity. That is, according to the above configuration, the component-side connection piece 111a and the target-side connection piece 111b, where a large amount of heat generation is assumed during energization, can be efficiently cooled.
[0024] Also, the component-side inlet / outlet 121 of the pair of refrigerant inlets / outlets 12 is a flow path opening that opens in the direction D13 perpendicular to the extension 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 stands on one of the front and back surfaces of the strip member 11 and communicates with the internal flow path 11a. According to 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 becomes easy to connect the internal flow path 11a to other flow paths having a similar flat shape. Also, by making the other one a cylindrical protrusion communicating with the internal flow path 11a, it becomes possible to connect to other-shaped flow paths such as a pipe shape, for example, and the degree of freedom regarding flow path connection can be improved.
[0025] Further, in the present embodiment, a pair of strip members 11 are provided so as to be connected one-to-one to a pair of component terminals E11 in the electric and electronic component E1, and the internal flow paths 11a of the pair of strip members 11 are connected by a flat connection pipe 13 formed of an insulating material. According to this configuration, the pair of strip members 11 connected to the electric and electronic component E1 can be efficiently cooled by a single refrigerant flow path configured by connecting the pair of internal flow paths 11a via the flat connection pipe 13. Further, since the connection of the internal flow paths 11a is performed by the flat connection pipe 13, the height can be reduced including this flat connection pipe 13.
[0026] Further, in the present embodiment, insulation treatment is performed on the surface portions 111c and 112b that constitute 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. According to this configuration, while effectively preventing a short circuit between the pair of component terminals E11 in the electric and electronic component E1, water, which is a general refrigerant having conductivity, can be used.
[0027] Next, a second embodiment will be described. The second embodiment is different from the first embodiment in the split configuration of the strip member. Hereinafter, the second embodiment will be described focusing on the differences from the first embodiment.
[0028] FIG. 5 is an exploded perspective view showing a conductive member with a refrigerant flow path according to the second embodiment. In FIG. 5, for the components equivalent to those of the first embodiment shown in the exploded perspective view of FIG. 2, only the elements necessary for the description are given the same reference numerals as in FIG. 2, and hereinafter, the description of those components will be omitted for the sake of brevity.
[0029] In the conductive member 2 with a refrigerant flow path according to the second embodiment, contrary to the above-described first embodiment, among the first component 211 and the second component 212 that constitute the strip member 21, the first component 211 is a groove member, and the second component 212 is a cover member. And, the first component 211 as the groove component is provided with a component-side connection piece 211a connected to the component terminal E11 of the electrical and electronic component E1 by a screw E12, and a target-side connection piece 211b connected to the object to be electrically connected. On the other hand, the second component 212 as the cover component in the present embodiment has a cover shape in which the component-side connection piece 111a and the target-side connection piece 111b are removed from the first component 111 in the above-described first embodiment. And, also in the present embodiment, a pair of strip members 21 constituted by the first component 211 and the second component 212 are connected by a flat connection pipe 13 equivalent to that in the first embodiment, and the conductive member 2 with a refrigerant flow path is constituted.
[0030] Needless to say, also with the conductive member 2 with a refrigerant flow path according to the second embodiment described above, it is possible to achieve both a reduction in height and an increase in current during energization, similar to the above-described first embodiment.
[0031] Next, a third embodiment will be described. The third embodiment is different from the first embodiment in that it has a configuration for directly cooling an electrical and electronic component. Hereinafter, the third embodiment will be described by focusing on the differences from the first embodiment.
[0032] FIG. 6 is a perspective view showing a conductive member with a refrigerant flow path according to the third embodiment, and FIG. 7 is an exploded perspective view of the conductive member with a refrigerant flow path shown in FIG. 6. Further, 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. And, FIG. 10 is a partial plan view of the peripheral structure of the electrical and electronic component in the conductive member with a refrigerant flow path shown in FIG. 6 as viewed from the direction of arrow V33 in FIG. 6. Note that in FIGS. 6 to 10, for the components equivalent to the components of the first embodiment shown in FIGS. 1 to 4, the same reference numerals as those in FIGS. 1 to 4 are given only to the components necessary for the description, and hereinafter, the description of those components will be omitted for the sake of brevity.
[0033] First, in the conductive member 3 with a refrigerant flow path according to the third embodiment, similar to the second embodiment described above, the first component 311 as a groove component is provided with a component-side connection piece 311a and a target-side connection piece 311b. The component-side connection piece 311a is connected to the component terminal E31 of the electrical and electronic component E3 by a screw E32, and the target-side connection piece 311b is connected to the electrical connection target of the electrical and electronic component E3. On the other hand, the second component 312 is merely a cover member as in the second embodiment. On the surface portions 311c and 312b that constitute the inner surface of the internal flow path 31a in the first component 311 and the second component 312, as shown in FIG. 8, the formation process of the insulating films 311c-1 and 312b-1 similar to those in the first embodiment is performed. Also, regarding the joining of the first component 311 and the second component 312, a watertight joint similar to that in the first embodiment is performed.
[0034] Here, in the present embodiment, in the electrical and electronic component E3, the component terminal E31 is provided on a terminal surface E3a different from that in the first embodiment described above. The electrical and electronic component E3 has a rectangular block-shaped appearance, and a pair of component terminals E31 are arranged along one side edge E3b in the terminal arrangement direction D15 on the terminal surface E3a, which is one of the six rectangular outer surfaces, the same as in the first embodiment. On the other hand, the terminal surface E3a is a surface that is displaced by 90° from the surface on which the component terminal E31 is provided in the electrical and electronic component E3 of the first embodiment. As a result, in the present embodiment, the pair of strip members 31 are connected to the electrical and electronic component E3 in a posture that is displaced by 90° from that in the first embodiment. Each component-side connection piece 311a of each of the pair of strip members 31 is connected to the component terminal E31 so as to extend along the terminal arrangement direction D15 on the terminal surface E3a.
[0035] And in this embodiment, among the pair of refrigerant inlets and outlets 32 in each strip plate member 31, the connection-side inlet and outlet 322 is the same as that in the first embodiment if the strip plate members 31 are separated. On the other hand, the component-side inlet and outlet 321 to which the flat connection pipe 13 is connected has the following bent flow path opening. That is, this component-side inlet and outlet 321 is a bent flow path opening that bends and extends in the direction D16 orthogonal to the front and back surfaces of the strip plate member 31 and opens as an extension of the internal flow path 31a. To configure this bent flow path 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 strip plate member 31 and bends and extends in the orthogonal direction D16 at the tip side. And in the second component 312 as a cover component, the portion that closes the above-mentioned bent groove is also a bent cover having a shape corresponding to the bent groove. By covering the bent groove of the first component 311 with the bent cover of the second component 312, the component-side inlet and outlet 321 as the above-mentioned bent flow path opening is configured. By connecting the component-side inlets and outlets 321 in the pair of strip plate members 31 with the same flat connection pipe 13 as in the first embodiment, the pair of internal flow paths 31a are connected. The connection of the flat connection pipe 13 to the component-side inlet and outlet 321 as the bent flow path opening is performed by sandwiching with a pair of flat groove members 131 and forming a watertight joint 13a as in the first embodiment, as shown in FIG. 9.
[0036] The flat connection pipe 13 is positioned at the surface attachment position P31 with respect to the terminal surface E3a in the electrical and electronic component E31 and the adjacent outer surface E3c that is continuously adjacent along one side edge E3b in the terminal arrangement direction D15 by connecting the component-side inlet and outlet 321 as the bent flow path opening. And in this embodiment, the flat connection pipe 13 positioned at this surface attachment position P31 is surface-attached to the adjacent outer surface E3c with one surface 132 of its front and back surfaces. Further, this surface attachment is performed via a heat transfer material 133 such as silicone grease, as shown in FIG. 10.
[0037] Needless to say, the conductive member 3 with a refrigerant flow path according to the third embodiment described above can also achieve both a reduction in height and an increase in current during energization, similar to the first embodiment described above.
[0038] Also, in the present embodiment, the flat connection pipe 13 is arranged to be surface-attached to the outer surface of the electric and electronic component E31 on one surface 132 of the front and back surfaces. According to this configuration, even when the electric and electronic component E3 itself generates heat, heat can be effectively transferred to the internal refrigerant through the flat connection pipe 13 surface-attached to its outer surface for cooling.
[0039] Also, in the present embodiment, the surface attachment of the flat connection pipe 13 to the electric and electronic component E3 is performed via a predetermined heat transfer material 133. According to this configuration, the heat of the electric and electronic component E3 can be more effectively transferred to the flat connection pipe 13 through the heat transfer material 133.
[0040] Also, in the present embodiment, component terminals E31 are arranged and provided in the terminal arrangement direction D15 on a terminal surface E3a which is one rectangular outer surface of the rectangular block-shaped electric and electronic component E3. And the flat connection pipe 13 is surface-attached to an adjacent outer surface E3c adjacent to this terminal surface E3a. Also, a pair of component-side inlets and outlets 321 connected by the flat connection pipe 13 are each a bent flow path opening positioned at the surface attachment position P31 with respect to the adjacent outer surface E3c of the flat connection pipe 13. According to this configuration, by surface-attaching the adjacent outer surface E3c to the terminal surface E3a of the electric and electronic component E3 and the flat connection pipe 13, the heat of the electric and electronic component E3 can be transferred to the flat connection pipe 13 while making the whole compact.
[0041] Next, the fourth embodiment will be described. The fourth embodiment is different from the first embodiment in the second member constituting the strip member and the connection structure of the pair of internal flow paths. Hereinafter, the fourth embodiment will be described focusing on the differences from the first embodiment.
[0042] FIG. 11 is a perspective view showing a conductive member with a refrigerant flow path according to the fourth embodiment, and FIG. 12 is an exploded perspective view of the conductive member with a refrigerant flow path shown in FIG. 11. Further, FIG. 13 is a plan view of the conductive member with a refrigerant flow path shown in FIG. 11 as viewed from the direction of arrow V41 in FIG. 11 with the electrical and electronic components removed. 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 flow paths are connected in the conductive member with a refrigerant flow path shown in FIG. 11 as viewed from the direction of arrow V43 in FIG. 11. And FIG. 16 is a cross-sectional view taken along line V44-V44 in FIG. 13. In FIGS. 11 to 16, for the components equivalent to the components of the first embodiment shown in FIGS. 1 to 4, the same reference numerals as those in FIGS. 1 to 4 are given only to the components necessary for the description, and the redundant description of those components will be omitted hereinafter.
[0043] In the conductive member 4 with a refrigerant flow path according to the fourth embodiment, the second component 412 that constitutes the strip member 41 is an outer wall portion that forms a part of the outer wall B11 of the device housing B1 formed of an insulating material. The second component 412 is a groove component in which a flow path groove 412a that constitutes a part of the internal flow path 41a is formed on one of the front and back surfaces of this outer wall portion. And the second component 412 is combined one-to-one with the first component 111, which is the same cover component as in the first embodiment, to constitute the strip member 41. The second component 412 as the outer wall portion in which the flow path groove 412a is formed is provided in a pair such that each flow path groove 412a extends along the terminal arrangement direction D15 of the pair of component terminals E11 in the electrical and electronic component E1.
[0044] Here, the joining of the second component 412, which is an outer wall portion made of insulating resin, and the first component 111, which is formed of conductive metal and serves as a bus bar, is performed by forming a watertight joint portion 41b so that the refrigerant does not leak from the internal flow path 41a, as shown in FIG. 14. The watertight joint portion 41b is formed by joining with an adhesive having watertight performance, welding in which the second component 412 is joined to the first component 111 while being partially heated and melted, or the like. Also, in this embodiment, water, which is a conductive fluid, is used as the refrigerant flowing through the internal flow path 41a. Therefore, a formation process of an insulating film 111c-1 is performed as an insulation treatment on a surface portion 111c that constitutes the inner surface of the internal flow path 41a in the first component 111.
[0045] Also, in this embodiment, on the side of the target-side connection piece 111b in the first component 111 among the pair of refrigerant inlets and outlets 42, it serves as the connection-side inlet and outlet 122 similar to the first embodiment. On the other hand, the component-side inlet and outlet 421 among the pair of refrigerant inlets and outlets 42 is provided at a position adjacent to the component-side connection piece 111a, which is a connection end portion fastened and fixed to the component terminal E11 with a screw E12 in the flow path groove 412a of the second component 412, and is a through hole that penetrates the outer wall portion.
[0046] And, as a connection structure of a pair of internal flow paths 41a configured by covering a pair of flow path grooves 412a one-to-one with a first component 111, a through-hole connection groove 43 shown in FIGS. 15 and 16 and a groove cover 44 shown in FIGS. 12 and 16 are provided. Here, between a pair of second components 412, an access opening B12 is provided for connecting the component-side connection piece 111a of the first component 111 and the component terminal E11 with a screw E12 from the other surface side opposite to the flow path groove 412a. The component-side entrance / exit 421 is provided at an adjacent position to the inner peripheral edge B12a of the access opening B12. Further, the component-side entrance / exit 421 is provided at two adjacent positions arranged in the terminal arrangement direction D15 around the inner peripheral edge B12a according to the pair of flow path grooves 412a extending along the terminal arrangement direction D15. As shown by an arrow D18, the through-hole connection groove 43 is formed to branch into two along the inner peripheral edge B12a of the access opening B12 from one component-side entrance / exit 421 and merge at the other component-side entrance / exit 421. The groove cover 44 is a resin ring plate formed to cover a pair of component-side entrance / exit 421s and a pair of through-hole connection grooves 43 extending along the inner peripheral edge B12a of the access opening B12.
[0047] As shown in FIG. 16, this groove cover 44 is formed by forming a watertight joint portion 44a in an outer wall portion which is the second component 412 so that refrigerant does not leak from the internal flow path 41a. The watertight joint portion 44a here is formed by joining with an adhesive having watertight performance, welding by partially heating and melting the second component 412 and the groove cover 44, or the like. Further, as shown in FIGS. 12 and 16, the groove cover 44 is configured such that a part of it enters the inside of the access opening B12. And a ring-shaped packing 45 is arranged between this cover-side entry portion 441 and the inner peripheral edge B12a of the access opening B12 to further ensure watertightness so that refrigerant does not leak from the internal flow path 41a to the inside of the access opening B12.
[0048] Needless to say, the conductive member 4 with a refrigerant flow path according to the fourth embodiment described above can also achieve both a reduction in height and an increase in current during energization, similar to the first embodiment described above.
[0049] Also, in the present embodiment, the second component 412 is an outer wall portion of the outer wall B11 of the device housing B1 where the flow path groove 412a is formed. Further, 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. Further, a through hole connection groove 43 that connects between 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. And a groove cover 44 that forms a connection flow path connecting the pair of internal flow paths 41a is provided by closing the groove opening in the through hole connection groove 43.
[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, on the side of the flow path groove 412a, the dimensional addition in the thickness direction D12 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 / outlets 421 that are each through holes, a through hole connection groove 43 that connects them, and a groove cover 44. Regarding this connection flow path as well, the dimensional addition in the thickness direction D12 is only the thickness of the groove cover 44, and in this regard as well, further reduction in height can be achieved.
[0051] In addition, in the present embodiment, an access opening B12 is provided between a pair of second components 412. The pair of component side entrances 421 are provided at a pair of adjacent positions with respect to the inner peripheral edge B12a of the access opening B12. The through-hole connection groove 43 is formed so as to branch into two along the inner peripheral edge B12a at one of the component side entrances 421 and merge at the other component side entrance 421. According to this configuration, by providing the access opening B12, the workability of connecting the first component 111 and the component terminal E11 of the electric and electronic component E1 can be improved. Further, by arranging the component side entrances 421 and the through-hole connection groove 43 that constitute the connection flow path connecting the internal flow path 41a so as to surround the access opening B12, this connection flow path can be provided compactly around the access opening B12. Furthermore, by forming the through-hole connection groove 43 to branch into two along the inner peripheral edge B12a of the access opening B12, while making the connection flow path compact, a sufficiently large flow path cross-sectional area can be obtained for the connection flow path.
[0052] Next, the fifth embodiment will be described. The fifth embodiment is different from the first embodiment in the configuration of the internal flow path and the refrigerant inlet / outlet in the strip member. Hereinafter, the fifth embodiment will be described focusing on the differences from the first embodiment.
[0053] FIG. 17 is a perspective view showing a conductive member with a refrigerant flow path according to the 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 the internal flow path and the electric and electronic components as viewed from the direction of arrow V52 in FIG. 17. Further, FIG. 20 is a bottom view showing the connection portion between one strip member and the electric and electronic components shown in FIG. 17 together with the internal flow path and the electric and electronic components as viewed from the direction of arrow V53 in FIG. 17. In FIGS. 17 to 20, for the components equivalent to the components of the first embodiment shown in FIGS. 1 to 4, only the components necessary for the description are given the same reference numerals as in FIGS. 1 to 4, and hereinafter, the description of these components will be omitted for the sake of brevity.
[0054] In the conductive member 5 with a refrigerant flow path according to the fifth embodiment, in each strip plate member 51, one end side is the connection side with the component terminal E11 of the electrical and electronic component E1, and the other end side is the connection side with the electrical connection target. And on either side, it is fastened and fixed to the other party by screwing. This strip plate member 51 is composed of a first component 511 and a second component 512 made of conductive metal having a rectangular plate shape that are mirror-symmetrical to each other.
[0055] In the first component 511, a first component side screw through hole 511a through which a screw E12 for screwing with the component terminal E11 penetrates is formed on one end side, and a similar first target side screw through hole 511b for screwing with the electrical connection target is formed on the other end side. Further, on one of the front and back surfaces of the first component 511, a first flow path groove 511c that constitutes a part of the internal flow path 51a is formed. This first flow path groove 511c passes between the first component side screw through hole 511a, the end face 511d on the component terminal E11 side, and a pair of side surfaces 511e along the length direction D11 on the component terminal E11 side and surrounds the periphery of the first component side screw through hole 511a in a U shape.
[0056] The second component 512 has a shape that is mirror-symmetrical to the first component 511 and is combined so as to overlap the formation surface of the first flow path groove 511c in the first component 511 to constitute the strip plate member 51. In this second component 512, a second component side screw through hole 512a and a second target side screw through hole 512b that communicate one-to-one with the first component side screw through hole 511a and the first target side screw through hole 511b are formed. Further, on the surface facing the formation surface of the first flow path groove 511c, a second flow path groove 512c that overlaps the first flow path groove 511c to constitute the internal flow path 51a is formed.
[0057] The joining of the first component 511 and the second component 512 is performed by overlapping the formation surfaces of the first flow channel groove 511c and the second flow channel groove 512c, and forming a watertight joint portion 51b at the boundary between the two so that the refrigerant does not leak from the internal flow channel 51a. The watertight joint portion 51b is formed by joining with an adhesive having watertight performance or the like. Also, in this embodiment, water, which is a fluid having conductivity, is used as the refrigerant. For this reason, an insulation process for forming an insulation film 511c-1 that electrically insulates the refrigerant from the first component 511 is performed on the inner surface of the first flow channel groove 511c. Also, an insulation process for forming a similar insulation film 512c-1 is performed on the inner surface of the second flow channel groove 512c.
[0058] And in this embodiment, the internal flow channel 51a formed in this way opens at each of a pair of strip side surfaces 51d along the length direction D11 of the strip member 51, and extends while bending in a U shape as described above midway between the pair of strip side surfaces 51d. The opening positions of each of the pair of strip side surfaces 51d in the internal flow channel 51a are coaxial positions in the width direction D17 of the strip member 51 in the vicinity of the first target side screw through hole 511b and the second target side screw through hole 512b. Also, a pair of refrigerant inlets and outlets 52 are attached to the openings of the internal flow channel 51a in each strip side surface 51d and serve as nipple members 521 for connecting a predetermined pipe and the internal flow channel 51a.
[0059] Needless to say, the conductive member 5 with a refrigerant flow path according to the fifth embodiment described above can also achieve both a reduction in height and an increase in current during energization, similar to the first embodiment described above.
[0060] In addition, in the present embodiment, a first flow path groove 511c is formed in the first component 511 so as to surround the periphery of the first component side screw through hole 511a in a U shape while passing between a pair of side surfaces 511e, and a similar second flow path groove 512c is also formed in the second component 512. According to this configuration, by overlapping the first component 511 and the second component 512, which are two mirror-symmetrical plate members, it is possible to further reduce the height of the strip member 51, that is, the conductive member 5 with a refrigerant flow path. Further, since the internal flow path 51a is configured to surround the peripheries of 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, it is possible to effectively cool the connection portion around the screw where the heat generation amount tends to increase during energization.
[0061] In addition, in the present embodiment, the refrigerant is water, that is, a fluid having conductivity, an insulating treatment is applied to the inner surface of the first flow path groove 511c, and a similar insulating treatment is also applied to the inner surface of the second flow path groove 512c. According to this configuration, by forming both the first component 511 and the second component 512 of a conductive metal, it is possible to reduce the electrical resistance of the conductive member 5 with a refrigerant flow path. Then, by applying an insulating treatment to the inner surfaces of the first flow path groove 511c and the second flow path groove 512c, it is possible to electrically isolate the refrigerant from energization by the conductive member 5 with a refrigerant flow path while using a general refrigerant such as water.
[0062] In addition, in the present embodiment, the internal flow path 51a opens at each of a pair of strip side surfaces 51d in the strip member 51, and extends while bending in a U shape midway from one of the pair of strip side surfaces 51d to the other. And a pair of refrigerant inlets / outlets 52 are formed as nipple members 521 attached to each opening of the internal flow path 51a. According to this configuration, since the nipple member 521 is attached to the opening of the internal flow path 51a at each of the pair of strip side surfaces 51d in the strip member 51, it is possible to reduce the height also for connection with other pipes.
[0063] Next, the sixth embodiment will be described. The sixth embodiment is a modification of the above-described fifth embodiment, and the shape of the internal flow path and the positions of the refrigerant inlets and outlets associated therewith are different from those of the fifth embodiment. Below, the sixth embodiment will be described by focusing on the differences from the fifth embodiment.
[0064] FIG. 21 is a top view similar to FIG. 19 related to the fifth embodiment, showing the conductive member with a refrigerant flow path according to the sixth embodiment. In FIG. 21, for the components equivalent to those of the fifth embodiment shown in FIGS. 17 to 20, only the components necessary for the description are given the same reference numerals as in FIGS. 17 to 20, and the duplicate description of these components will be omitted below.
[0065] In the conductive member 6 with a refrigerant flow path according to the sixth embodiment, the internal flow path 61a of the strip member 61 is formed so as to surround 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 in a U shape, which is the same as in the fifth embodiment. However, in this embodiment, the opening positions of the internal flow path 61a on the pair of strip side surfaces 61d are different from those of the fifth embodiment. That is, the opening position on one strip side surface 61d is at a substantially central position in the length direction D11, while the opening position on the other strip side surface 61d is offset toward the end surface 611d on the component terminal E11 side of the electrical and electronic component E1. And the same nipple member 521 as in the fifth embodiment is attached to these openings at different positions as a pair of refrigerant inlets and outlets 52.
[0066] Needless to say, the conductive member 5 with a refrigerant flow path according to the sixth embodiment described above can also achieve the same effect as in the fifth embodiment, that is, the same effect as in the first embodiment above, of achieving both a reduction in height and an increase in current during energization.
[0067] In addition, in the above-described fifth and sixth embodiments, the refrigerant flow path-provided conductive members 5 and 6 are exemplified in which the attachment positions of the nipple members 521 as the refrigerant inlets / outlets are different on the belt side surfaces 51d and 61d of the belt plate members 51 and 61. Thus, in the fifth and sixth embodiments, the refrigerant inlets / outlets can be set at arbitrary positions during design.
[0068] Next, a seventh embodiment will be described. The seventh embodiment is a modification of the above-described fifth embodiment, and is different from the fifth embodiment in that a plurality of refrigerant flow path-provided conductive members are connected in the width direction. Hereinafter, the seventh embodiment will be described by focusing on the differences from the fifth embodiment.
[0069] FIG. 22 is a perspective view showing a refrigerant flow path-provided conductive member according to the seventh embodiment, and FIG. 23 is a plan view of the refrigerant flow path-provided conductive member shown in FIG. 22 as viewed from the direction of arrow V71 in FIG. 22. In FIGS. 22 and 23, for the components equivalent to those of the fifth embodiment shown in FIGS. 17 to 20, only the components necessary for the description are given the same reference numerals as in FIGS. 17 to 20, and the overlapping description of those components will be omitted hereinafter.
[0070] The conductive member 7 with a refrigerant flow path according to the seventh embodiment has the same configuration as the conductive member 5 with a refrigerant flow path according to the fifth embodiment described above. However, in this embodiment, a plurality (two in the illustrated example) of electrical and electronic components E1 to be connected are linearly arranged in the width direction D17 of the strip member 51 connected to the component terminal E11. And, of a pair of strip members 51 corresponding to a pair of adjacent electrical and electronic components E1, the nipple member 521 of the refrigerant inlet / outlet 52 on one side and the nipple member 521 of the refrigerant inlet / outlet 52 on the other side are linearly arranged in the width direction D17. And the nipple members 521 arranged in this way are connected by a straight pipe 71 extending in the width direction D17. At the tip of each nipple member 521, a retaining portion 521a is formed which enters the inside of the straight pipe 71 and locks onto the inner surface of the pipe from the inside. The nipple members 521 of the pair of refrigerant inlets / outlets 52 in one strip member 51 are coaxial in the width direction D17 of the strip member 51 in the vicinity of the first target-side screw through-hole 511b and the second target-side screw through-hole 512b as described for the fifth embodiment. For this reason, in this embodiment, the same strip member 51, that is, the same conductive member 5 with a refrigerant flow path, can connect adjacent nipple members 521 to each other simply by arranging two in the width direction D17 with a straight pipe 71. As a result, the internal flow paths 51a of adjacent strip members 51 are connected by the straight pipe 71.
[0071] Needless to say, the conductive member 7 with a refrigerant flow path according to the seventh embodiment described above can also achieve both a reduction in height and an increase in current during energization, similar to the fifth embodiment described above.
[0072] In addition, in the present embodiment, the refrigerant inlets / outlets 52 in one of the pair of strip members 51 adjacent to each other and the refrigerant inlets / outlets 52 in the other are arranged linearly in the width direction D17 and are connected by a straight pipe 71 extending in the width direction D17. According to this configuration, since the internal flow paths 51a of the plurality of conductive members 7 with refrigerant flow paths are connected by the straight pipe 71, the overall configuration of the refrigerant flow path for cooling related to the electrical connection of the plurality of electrical and electronic components E1 can be simplified. By this simplification, it is possible to achieve space saving and weight reduction in the overall configuration for cooling related to the electrical connection of the plurality of electrical and electronic components E1.
[0073] Next, the eighth embodiment will be described. The eighth embodiment is a modification of the above-described seventh embodiment, and the connection position by the straight pipe is different from that of the seventh embodiment. Hereinafter, the eighth embodiment will be described by focusing on the differences from the seventh embodiment.
[0074] FIG. 24 is a plan view equivalent to FIG. 23 showing only a pair of adjacent strip members connected by a single straight pipe, which are the conductive members with refrigerant flow paths according to the eighth embodiment. In FIG. 24, for the components equivalent to those of the seventh embodiment shown in FIGS. 22 and 23, only the components necessary for the description are given the same reference numerals as in FIGS. 22 and 23, and the redundant description of these components will be omitted hereinafter.
[0075] In the conductive member 8 with a refrigerant flow path according to the eighth embodiment, the opening position of the internal flow path 81a of the strip member 81 is slightly closer to the component terminal E11 of the electrical and electronic component E1 than in the seventh embodiment. A nipple member 521 forming the refrigerant inlet / outlet 52 is attached at a position closer to the component terminal E11, and adjacent nipple members 521 are connected by a straight pipe 71 at a position closer to the component terminal E11 so that the internal flow paths 81a are connected to each other. Also in this embodiment, the opening positions of the internal flow paths 81a in each strip member 81, that is, the attachment positions of the nipple members 521, are coaxially aligned in the width direction D17. And by utilizing this arrangement, just by simply arranging two of the same conductive members 8 with refrigerant flow paths side by side in the width direction D17, adjacent nipple members 521 can be connected by a straight pipe 71.
[0076] Needless to say, also with the conductive member 8 with a refrigerant flow path according to the eighth embodiment described above, it is possible to achieve both a reduction in height and an increase in current during energization, similar to the above-described seventh embodiment.
[0077] Next, the ninth embodiment will be described. The ninth embodiment is a further modification of the above-described seventh embodiment, and the connection position by the straight pipe is different from both the seventh and eighth embodiments. Below, the ninth embodiment will be described by focusing on the differences from the seventh and eighth embodiments.
[0078] FIG. 25 is a diagram showing a conductive member with a refrigerant flow path according to the ninth embodiment in a plan view equivalent to FIG. 23. In FIG. 25, for the components equivalent to those of the seventh embodiment shown in FIGS. 22 and 23, only the elements necessary for the description are given the same reference numerals as in FIGS. 22 and 23, and hereinafter, duplicate description of these components will be omitted.
[0079] In the conductive member 9 with a refrigerant flow path according to the ninth embodiment, the opening positions of the internal flow path 91a in the strip member 91, that is, 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 electrical and 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. And the internal flow path 91a connects the nipple members 521 at positions thus shifted in the length direction D11 in a bent shape that U-shapedly surrounds the first component side screw through hole 511a and the second component side screw through hole 512a in the middle.
[0080] Here, in this embodiment, the mounting 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 flow paths are simply arranged side by side in the width direction D17, the nipple members 521 of the refrigerant inlet / outlet 52 cannot be connected by 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 can be linearly arranged in the width direction D17 and connected by the straight pipe 71. That is, in this embodiment, between two adjacent conductive members 9 with refrigerant flow paths, one strip member 91 is connected to the component terminal E11 of each electrical and electronic member E1 in an inverted state where it is the reverse of the other strip member 91.
[0081] Needless to say, also with the conductive member 9 with a refrigerant flow path according to the ninth embodiment described above, it is possible to achieve both a reduction in height and an increase in the current during energization, similar to the above-described seventh embodiment.
[0082] In addition, in the above-described seventh to ninth embodiments, the refrigerant flow path-provided conductive members 7 to 9 in which the relative positions in the length direction D11 of the pair of refrigerant inlets and outlets 52 in one strip plate member 51, 81, 91 are different are illustrated. Thus, in the seventh to ninth embodiments, the refrigerant inlets and outlets can be set at arbitrary positions during design. However, when the pair of refrigerant inlets and outlets 52 are set at positions shifted in the length direction D11, as described in the ninth embodiment, it is possible to connect them with the straight pipe 71 by inverting one of the pair of adjacent strip plate members 91 with respect to the other.
[0083] Note that the first to ninth embodiments described above merely show typical forms of the refrigerant flow path-provided conductive members. The refrigerant flow path-provided conductive members are not limited to these and can be implemented in various modified forms.
[0084] For example, in the above-described embodiments, as an example of the refrigerant flow path-provided conductive member, the refrigerant flow path-provided conductive members 1 to 9 for connecting each of the pair of component terminals E11 in the relay, which is the electrical and electronic component E1, to the electrical connection target are illustrated. However, the refrigerant flow path-provided conductive member is not limited to this, and the electrical and electronic component to be connected may be an electrical component other than the relay or other electronic components.
[0085] In addition, in the above-described embodiments, as an example of the refrigerant flow path-provided conductive member, the liquid-cooled refrigerant flow path-provided conductive members 1 to 9 in which water, which is a conductive liquid, flows through the internal flow paths 11a to 91a are illustrated. However, the refrigerant flow path-provided conductive member is not limited to this, and the refrigerant may be a non-conductive liquid or an air-cooling gas. When a non-conductive liquid or an air-cooling gas is employed as the refrigerant, insulation treatment of the inner surface on the first component side made of conductive metal in the internal flow path becomes unnecessary.
[0086] In addition, in the above-described embodiments, as an example of the conductive member with a refrigerant flow path, the conductive members 1 to 9 with a refrigerant flow path including a pair of strip members 11 to 91 are illustrated. However, the conductive member with a refrigerant flow path is not limited to this, and it may have only one strip member or three or more strip members. When there is only one strip member, the strip member functions as the conductive member with a refrigerant flow path itself.
[0087] In addition, in the above-described first to fourth embodiments, as an example of the conductive member with a refrigerant flow path, the conductive members 1 to 4 with a refrigerant flow path in which the internal flow paths 11a to 41a of a pair of strip members 11 to 41 are connected by the flat connection pipe 13 or the through-hole connection groove 43 are illustrated. However, the conductive member with a refrigerant flow path is not limited to this. For example, as illustrated in the fifth to ninth embodiments, even if a pair of strip members 51 to 91 are provided, they may not be connected to each other. Among these examples, in the examples of the seventh to ninth embodiments, each of the strip members 51 to 91 is connected to the strip members 51 to 91 of other conductive members 7 to 9 with a refrigerant flow path via the straight pipe 71. In this way, each of the pair of strip members 51, 81, 91 that are not connected in one conductive member 5 to 9 with a refrigerant flow path can be said to function as an independent conductive member with a refrigerant flow path by itself.
[0088] In addition, in the above-described first to third, fifth to ninth embodiments, as an example of the strip member, strip members 11, ···, 31, 51, 81, 91 in which both the first components 111, ···, 311, 511 and the second components 112, ···, 312, 512 are formed of a conductive metal are exemplified. Further, in the above-described fourth embodiment, as an example of the strip member, a strip member 41 that forms a part of the outer wall B11 of the device housing B1 in which the first component 111 is formed of a conductive metal and the second component 412 is formed of an insulating material is exemplified. However, the strip member is not limited to these, and if the first component responsible for the electrical connection of the electrical and electronic components is formed of a conductive metal, the second component may be formed of an insulating material regardless of its shape or the like.
