Description

  The present invention relates to a wiring member.

  BACKGROUND ART Wiring members are used in a wide range of industrial fields as conductive paths provided in electric devices, electronic devices, and the like. Generally, the wiring member is made of a metal material such as aluminum and copper, and generates heat due to electric resistance inherent to the metal when energized. When the current flowing through the wiring member is small, the calorific value is small, but when a large amount of current flows, the calorific value increases, and the temperature of the wiring member becomes high. Such heat generation causes malfunctions and failures of the electric equipment and the like. Therefore, general electric devices and the like are provided with a cooling mechanism for cooling and radiating heat generated in the wiring member (Patent Documents 1 to 3).

Patent Literature 1 discloses a cooling device including a plurality of projecting heat radiation units. In the cooling device described in Patent Literature 1, the protruding heat radiating portion is filled with a cotton-like body containing a volatile liquid. Such a cooling device has a plurality of protrusions filled with the flocculent body, thereby enhancing the cooling effect by the heat of vaporization of the volatile liquid.
Patent Literature 2 discloses a heat sink in which a linear coil is provided on bulk copper. Such a heat sink transfers heat generated in a chip or the like of an electronic device to bulk copper and radiates heat from a linear coil as a heat radiating portion.
Patent Literature 3 discloses a wiring member used for a power supply rod of a plasma processing apparatus. The power supply rod described in Patent Document 3 includes a conductive wiring member and a hollow portion for flowing a coolant such as air. The power supply rod of Patent Literature 3 has a plurality of protrusions provided in the hollow portion as a heat radiating portion, thereby enhancing the cooling effect of the refrigerant and preventing overheating of the wiring member.

JP-A-7-335797 JP 2004-311711 A Japanese Patent No. 4183059

However, the cooling mechanisms described in Patent Documents 1 to 3 simply increase the surface area of the heat radiating portion to increase the cooling efficiency, and thus cannot obtain a sufficient cooling effect.
The cooling device described in Patent Literature 1 has a protruding portion and therefore requires a considerable thickness, and is not suitable for space saving. Similarly, the heat sink described in Patent Literature 2 has a linear coil and is not suitable for saving space. Further, the heat sink described in Patent Literature 2 includes bulk copper and is heavy and is not suitable for weight reduction. It is difficult to adopt the cooling mechanisms of Patent Documents 1 to 3, which require a considerable thickness, in electrical devices and the like that require space saving such as miniaturization and thinning.
As described above, the cooling mechanisms of Patent Literatures 1 to 3 have an insufficient cooling effect and are not suitable for miniaturization and thinning.

Further, in a wiring member or the like used for an electric device or the like, for example, the central portion of the wiring member tends to be relatively hot. In order to efficiently cool the hot central portion, it is effective to locally cool the hot central portion.
However, since the cooling mechanisms described in Patent Literatures 1 to 3 are simply attached so as to entirely cover a heating element such as a wiring member, it cannot be said that local cooling can be realized.

  The present invention has been made in view of the above background, and it is an object of the present invention to provide a wiring member which has an excellent cooling effect, is easily reduced in size and thickness, and enables local cooling.

The present invention has the following aspects.
[1] A metal fiber sheet including at least one of a copper fiber and an aluminum fiber, and a cooling mechanism for cooling the metal fiber sheet, wherein at least a part of the fibers included in the metal fiber sheet are included. Wiring member bound by.
[2] The wiring member according to [1], wherein the cooling mechanism includes a container that stores the metal fiber sheet, and a refrigerant introduction unit that introduces a refrigerant into the container.
[3] The wiring member according to [2], wherein the container is formed of at least one selected from the group consisting of a copper plate, an aluminum plate, a copper foil, and an aluminum foil.
[4] The wiring member according to [1], wherein the cooling mechanism includes a support for supporting the metal fiber sheet, and a hollow portion serving as a flow path of a coolant is provided inside the support.
[5] The wiring member according to [4], wherein the support has a through-hole through which the coolant is drawn out from the hollow portion toward the metal fiber sheet.
[6] The wiring member according to any one of [1] to [5], wherein an insulator covering at least one of the metal fiber sheet and the cooling mechanism is provided.
[7] The wiring member according to any one of [1] to [6], wherein the fibers are bound by sintering.

  ADVANTAGE OF THE INVENTION According to this invention, the wiring member which is excellent in a cooling effect, is easy to reduce in size and thickness, and enables local cooling can be provided.

[First Embodiment]
Hereinafter, the wiring member of the first embodiment to which the present invention is applied will be described in detail with reference to the drawings, but the wiring member of the present invention is not limited to the following description. In the drawings used in the following description, the dimensional ratios and the like of the components are not always the same as the actual ones.

FIG. 1 is a perspective view showing a wiring member 1 according to the first embodiment. As shown in FIG. 1, the wiring member 1 according to the first embodiment has a metal fiber sheet 6 and a cooling mechanism 7.
The wiring member 1 of the first embodiment can have an arbitrary three-dimensional shape employed in a known wiring member according to the purpose of use and the like. Such a three-dimensional shape may be, for example, any of a columnar shape, an elliptical columnar shape, and a polygonal columnar shape. Hereinafter, a polygonal columnar wiring member will be described as an example of an embodiment of the present invention, but the shape of the wiring member of the present invention is not limited to a polygonal columnar member.

(Metal fiber sheet)
The metal fiber sheet 6 includes at least one of a copper fiber and an aluminum fiber. Since the metal fiber sheet 6 contains at least one of a copper fiber and an aluminum fiber, the metal fiber sheet 6 is efficiently cooled by a refrigerant described below. The metal fiber sheet 6 may include only a copper fiber, may include only an aluminum fiber, or may include a copper fiber and an aluminum fiber. The metal fiber sheet 6 may further include metal fibers other than copper fibers and aluminum fibers, and fibers other than metal fibers, as long as the conductivity is not impaired.
Copper fiber or aluminum fiber is excellent in balance between rigidity and plastic deformability, and thus can provide the wiring member 1 of the first embodiment with stable and sufficient conductivity. Examples of metals other than copper and aluminum include, but are not particularly limited to, stainless steel, iron, nickel, and chromium. The metal other than copper may be a noble metal such as gold, platinum, silver, palladium, rhodium, iridium, ruthenium, and osmium.
Components other than metals include polyolefins such as polyethylene terephthalate (PET) resin, polyvinyl alcohol (PVA), polyethylene, and polypropylene, polyvinyl chloride resin, aramid resin, nylon, and acrylic resin, and fibrous materials thereof. Organic substances having a binding property and a supporting property. These organic substances may be used, for example, to assist and improve the shape retention during the production of the metal fiber sheet. In the case where an organic material is used for the bonding portion between fibers, it is preferable to select an organic material in consideration of heat resistance.

In the metal fiber sheet 6, fibers included in the metal fiber sheet 6 are bound at least in part. The fibers contained in the metal fiber sheet 6 are bound together, for example, when the metal fibers of the present embodiment include a copper fiber and an aluminum fiber, the copper fibers, the aluminum fibers, Alternatively, it means that the copper fiber and the aluminum fiber are physically fixed to form a binding portion.
In the metal fiber sheet 6, the fibers included in the metal fiber sheet 6 may be directly fixed to each other at the binding portion. In the metal fiber sheet 6, the fibers included in the metal fiber sheet 6 may be indirectly fixed to each other via a copper component, an aluminum component, or a metal component other than copper and aluminum.
Since the fibers included in the metal fiber sheet 6 are bound at least in part, the wiring member 1 of the first embodiment can have conductivity. The transmission attenuation rate of the metal fiber sheet 6 is preferably within ± 5% of the transmission attenuation rate difference from the solid material of the same material. If the transmission attenuation difference of the metal fiber sheet 6 is within ± 5%, the wiring member 1 of the first embodiment can have the same conductivity as a conventional wiring member.

Since the fibers included in the metal fiber sheet 6 are bound at least in part, the metal fiber sheet 6 can have voids formed of copper fibers or aluminum fibers in the sheet. Such voids may be formed by, for example, entanglement of copper fibers or aluminum fibers. When the metal fiber sheet 6 has the voids, a refrigerant described later is introduced into the metal fiber sheet 6, so that heat is easily removed from the fibers constituting the metal fiber sheet 6, and the cooling efficiency of the metal fiber sheet 6 is excellent. It will be easier.
The thermal conductivity of the metal fiber sheet 6 is preferably 10 W / m · K or more, more preferably 50 W / m · K or more. When the thermal conductivity of the metal fiber sheet 6 is 10 W / m · K or more, the cooling efficiency of the wiring member 1 of the first embodiment is easily improved.
The metal fiber sheet 6 preferably has fibers contained in the metal fiber sheet 6 bound by sintering. Since the fibers are bonded to each other by sintering, the conductivity, heat conductivity, and homogeneity of the metal fiber sheet 6 are easily stabilized.

The structure of the metal fiber sheet 6 is not particularly limited as long as it is sheet-like, and may have any sheet structure. For example, the sheet structure of the metal fiber sheet 6 may be a nonwoven fabric in which copper fibers or aluminum fibers are randomly entangled, a regular woven fabric, or a mesh material. The surface of the metal fiber sheet 6 may be flat, may be corrugated, and may have irregularities, and is not particularly limited.
FIG. 2 is a sectional view taken along line II-II of the wiring member of FIG. The thickness D in the vertical direction of the metal fiber sheet 6 shown in FIG. 2 is preferably in the range of 100 μm to 5 mm. When the thickness D of the metal fiber sheet 6 is 100 μm or more, the cooling effect of the wiring member 1 tends to be excellent. If the thickness D of the metal fiber sheet 6 is 5 mm or less, the thickness of the wiring member 1 is easily reduced. The thickness D of the metal fiber sheet 6 can be appropriately adjusted in a pressing step described later.
The basis weight of the metal fiber sheet 6 ^is preferably in the range of ^{10g / m 2 ~1000g / m 2} . If the basis weight of the metal fiber sheet 6 is 10 g / m ² or more, it is easy to sufficiently exert a cooling effect. If the basis weight of the metal fiber sheet 6 is 1000 g / m ² or less, the weight and thickness of the metal fiber sheet 6 are easily reduced, so that the wiring member 1 is easily reduced in weight and thickness.

The average fiber diameter of the copper fiber or the aluminum fiber can be arbitrarily set as long as the effect of the present invention is not impaired. The average fiber diameter of the copper fiber or the aluminum fiber is preferably 1 μm to 30 μm, and more preferably 2 μm to 20 μm. When the average fiber diameter of the copper fiber or the aluminum fiber is less than 1 μm, the rigidity of the copper fiber or the aluminum fiber is reduced, and so-called lump is easily generated when the metal fiber sheet 6 is manufactured. When the lumps are generated, the electrical conductivity, thermal conductivity, and homogeneity of the metal fiber sheet 6 become difficult to stabilize. When the average fiber diameter of the copper fiber or the aluminum fiber exceeds 30 μm, the rigidity of the copper fiber or the aluminum fiber may hinder fiber entanglement.
The shape of the cross section perpendicular to the longitudinal direction of the copper fiber or the aluminum fiber can be any shape. The shape of such a cross section may be any shape such as, for example, a circle, an ellipse, a substantially square, and an irregular shape.

The average fiber length of the copper fiber or the aluminum fiber can be arbitrarily set within a range that does not impair the effects of the present invention. The average fiber length of the copper fiber or the aluminum fiber is preferably in the range of 1 mm to 10 mm, and more preferably in the range of 3 mm to 5 mm. When the average fiber length of the copper fiber or the aluminum fiber is in the range of 1 mm to 10 mm, the conductivity, heat conductivity, and homogeneity of the wiring member 1 are easily stabilized.
The copper fiber or the aluminum fiber preferably has an aspect ratio of 33 to 10,000. When the aspect ratio is less than 33, entanglement of the copper fiber or the aluminum fiber is unlikely to occur, and the strength of the wiring member 1 may be reduced. If the aspect ratio exceeds 10000, the homogeneity of the metal fiber sheet 6 may be reduced, and the conductivity of the wiring member 1 may not be stable.

  The lower limit of the space factor of the metal fiber sheet 6 is preferably 2% or more, more preferably 4% or more, and even more preferably 5% or more. The upper limit of the space factor of the metal fiber sheet 6 is preferably 65% or less, and more preferably 60% or less. If the space factor is less than 2%, the pressure loss at the time of introducing the refrigerant can be suppressed, but the cooling effect may be reduced due to insufficient fiber amount. If the space factor exceeds 65%, the pressure loss at the time of introducing the refrigerant may increase.

The coefficient of variation (CV value) of the basis weight defined in JIS Z8101 per 1 cm ^{2 of the} metal fiber sheet 6 is preferably 10% or less. Since the grammage is an index indicating the weight per unit volume, the fact that the coefficient of variation of the grammage is equal to or less than a certain value means that the conductivity, thermal conductivity, and space factor of the metal fiber sheet 6 are also stable. It can be said that this is the value obtained. That is, if the coefficient of variation of the basis weight of the metal fiber sheet 6 is 10% or less, extremely small lumps and voids are unlikely to be present in the metal fiber sheet 6, the uniformity of the metal fiber sheet 6 is excellent, and the wiring member is 1 is hard to increase the transmission attenuation rate and the value of the thermal conductivity is easily stabilized.

  Examples of a method for producing the metal fiber sheet 6 include a dry method of compression molding and a method of papermaking by a wet papermaking method. When the metal fiber sheet 6 is manufactured by a wet papermaking method, a fiber entanglement treatment step of tangling copper fibers, aluminum fibers, or the like with each other may be performed after the wet papermaking. When sintering the metal fiber sheet 6, the metal fiber sheet 6 may be sintered in a vacuum or a non-oxidizing atmosphere at a temperature equal to or lower than the melting point of the copper fiber or the aluminum fiber. In addition to these, in the manufacturing process of the metal fiber sheet 6, a pressing process such as pressing may be appropriately performed to reduce voids formed between the fibers and improve homogeneity. In order to appropriately adjust the thickness D of the metal fiber sheet 6 by the pressing step, the pressure at the time of pressing may be appropriately adjusted.

(Cooling mechanism of the first embodiment)
The cooling mechanism 7 of the first embodiment cools the metal fiber sheet 6. The cooling mechanism 7 includes a container 10 and a refrigerant introduction unit (not shown) for introducing a refrigerant into the container.
The container 10 stores the metal fiber sheet 6. The shape of the container 10 is not particularly limited, and may have any structure and shape. The container 10 can be made of a known metal material, a known ceramic material, a known resin material, or the like. The metal material is not particularly limited, and copper, aluminum, and metal materials other than copper and aluminum can be used. Examples of the metal other than copper and aluminum include the same metals as the “metal other than copper that can form the metal fiber sheet 6” described above. As the ceramic material, alumina, zirconia, barium titanate, silicon carbide, silicon nitride, aluminum nitride, or the like can be used. Among these, the material of the container 10 is preferably made of a metal material from the viewpoints of conductivity and heat conductivity. For example, in the wiring member 1 of the first embodiment, the container 10 can be made of a conductive material such as a copper plate, an aluminum plate, a copper foil, and an aluminum foil. That is, the container 10 can be composed of at least one selected from the group consisting of a copper plate, an aluminum plate, a copper foil, and an aluminum foil. When the container 10 is made of these conductive materials, the container 10 can be provided with conductivity. The container 10 may be made of a material other than the conductive material, and is not particularly limited. That is, in the wiring member 1, it may be possible to energize the container 10, but there is no particular limitation.

In the wiring member 1 of the first embodiment, the cooling mechanism 7 includes a refrigerant introduction unit (not shown) for introducing a refrigerant into the housing 10. Thereby, the refrigerant can be introduced into the housing 10. The refrigerant is not particularly limited, and includes known refrigerants used in industrial fields such as electric devices and electronic devices. Examples of the refrigerant include air, a fluorine-based inert liquid, and an insulating oil. The refrigerant introduction means is not particularly limited, and may be a known refrigerant introduction means such as a compressor and a liquid pump.
By introducing the coolant into the housing 10, the metal fiber sheet 6 housed in the housing 10 can be cooled. Since the metal fiber sheet 6 is made of copper fiber or aluminum fiber, it is efficiently cooled by the refrigerant.

The structure of the container 10 is a structure capable of introducing a refrigerant into the container 10. In the wiring member 1 of the first embodiment, both ends of the container 10 are open ends. That is, the container 10 includes the first open end 11 and the second open end 12.
The refrigerant introduced into the container 10 from the first open end 11 cools the wiring member 1 from the inside, and is drawn out from the second open end 12. By providing the first open end 11 and the second open end 12, the refrigerant is introduced into the housing 10 from the first end of the housing 10, and the refrigerant is introduced from the second open end 12. Can be derived.
As described above, in the wiring member 1 of the first embodiment, the refrigerant introduced into the housing 10 cools the metal fiber sheet 6 and is derived from the housing 10. When the metal fiber sheet 6 of the wiring member 1 according to the first embodiment generates heat, the cooling medium is continuously introduced into the housing 10 so that the metal fiber sheet 6 can be cooled. Further, the temperature of the refrigerant introduced into the housing 10 is increased by cooling the metal fiber sheet 6 compared to before the introduction. In the wiring member 1 of the first embodiment, the coolant whose temperature has increased is led out from the second opening end portion 12, so that the metal fiber sheet 6 can be efficiently cooled.

In the wiring member 1 of the first embodiment, the cross-sectional shapes of the first and second opening end portions 11 and 12 and the area of the opening surface can be arbitrarily selected. The cooling effect of the wiring member 1 can be adjusted by appropriately selecting the areas of the opening surfaces of the first and second opening ends 11 and 12. For example, when it is desired to further enhance the cooling effect of the wiring member 1, the efficiency of introducing the refrigerant may be increased by increasing the area of the opening surface of the first opening end 11.
When the area of the opening surface of the first opening end 11 is small and it is difficult to introduce the refrigerant, or when it is desired to improve the cooling efficiency, a known refrigerant introducing means for introducing the refrigerant into the housing 10 is used. Pressurizing means can be used. Such pressurizing means is not particularly limited, and includes known pressurizing means such as a compressor and a pressurizing pump.
The housing 10 of the wiring member 1 of the first embodiment has open ends at both ends. However, the wiring member of the first embodiment is not limited to this, and only one of the ends is open. It may be an end.

  When the container 10 is made of metal, the metal fiber sheet 6 and the container 10 are preferably bonded. As a method for binding the metal fiber sheet 6 and the container 10, for example, the container 10 can be arranged on the metal fiber sheet 6 in a manner as shown in FIG. 1 and sintered.

(Other configurations)
The wiring member 1 of the first embodiment can have, in addition to the metal fiber sheet 6 and the container 10 described above, a known configuration of a known wiring member as another configuration. For example, the wiring member 1 can include an insulator that covers the cooling mechanism 7 as an example of another configuration. Such an insulator can cover the outer surface of the container 10. When the wiring member 1 has an insulator, it can be easily applied to various uses requiring insulation. The insulating material is not particularly limited, and includes a known insulating material such as a resin. In addition to the above-described insulator, the wiring member 1 can have a configuration provided with a known wiring member such as a terminal for energization as an example of another configuration.

In the wiring member 1 of the first embodiment, the entire area of the metal fiber sheet 6 is accommodated in the housing 10, but even if a part of the area of the metal fiber sheet 6 is housed in the housing 10. Good. In this case, by introducing the refrigerant into the container 10, it is possible to locally cool the metal fiber sheet 6 in a part of the region accommodated in the container 10.
Further, in the wiring member 1 of the first embodiment described above, both ends of the container 10 are open ends, but both ends may be closed ends. In this case, a coolant inlet for introducing a coolant into the housing 10 must be provided at an arbitrary position of the housing 10. When such a refrigerant inlet is provided in the container 10, a refrigerant outlet from which the refrigerant is discharged from the inside of the container 10 may be further provided at an arbitrary position of the container 10.

(Operation and Effect of First Embodiment)
The wiring member 1 of the first embodiment described above is different from the wiring member 1 of the first embodiment in that the metal fiber sheet 6 is made of copper fiber or aluminum fiber. Cooled efficiently by By introducing the refrigerant into the housing 10 of the wiring member 1, the wiring member 1 can continuously hold the refrigerant inside the metal fiber sheet 6. Further, since the metal fiber sheet 6 of the wiring member 1 is housed in the housing 10, the entire surface of the metal fiber sheet 6 is forcibly cooled by the refrigerant. As described above, the cooling effect of the wiring member 1 is significantly improved as compared with the conventional wiring member in which the conductor is formed of a solid material.
In addition, the wiring member 1 of the first embodiment can be reduced in thickness and weight by having the metal fiber sheet 6 suitable for use in reducing the thickness and weight.

[Second embodiment]
Hereinafter, the wiring member 2 of the second embodiment to which the present invention is applied will be described. In the wiring member 2 of the second embodiment shown in FIGS. 3, 5, and 6, the same components as those of the wiring member 1 of the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
FIG. 3 is a perspective view showing the wiring member 2 of the second embodiment. As shown in FIG. 3, the wiring member 2 of the second embodiment has a metal fiber sheet 6 and a cooling mechanism 8. The cooling mechanism 8 of the second embodiment cools the metal fiber sheet 6.

(Cooling mechanism of the second embodiment)
As shown in FIG. 3, the cooling mechanism 8 of the second embodiment includes a support 20. The support 20 supports the metal fiber sheet 6.
Inside the support body 20, there is provided a hollow portion 23 serving as a coolant flow path. The support body 20 is also cooled by the coolant flowing through the hollow portion 23. The cooling mechanism 8 of the second embodiment can cool the metal fiber sheet 6 mainly by the refrigerant introduced into the cooling mechanism 8.

  The support 20 can be made of a known metal material, a known ceramic material, a known resin material, or the like. Examples of the metal material include stainless steel, copper, and aluminum. Examples of the ceramic material include alumina, zirconia, barium titanate, silicon carbide, silicon nitride, and aluminum nitride. Examples of the resin material include polyacrylic acid resins such as polymethacrylic acid and polycyanoacrylic acid (polycyanoacrylate); polyvinylpyrrolidone resins; polyester resins such as polyethylene terephthalate; polypropylene resins; fluorine resins such as polytetrafluoroethylene; Polyimide resin; polyamide resin containing aramid; polyparaphenylene benzobisoxazole resin, and the like. From the viewpoint of cooling efficiency, a metal material having high thermal conductivity is preferable as the material of the support 20.

  FIG. 4 is a top view showing the cooling mechanism 8 of FIG. As shown in FIG. 4, a plurality of through holes 25 penetrating from the upper surface of the support 20 to the hollow portion 23 inside the support 20 are provided on the upper surface of the support 20. Since the through hole 25 is provided on the upper surface of the support 20, the refrigerant flowing through the hollow portion 23 is drawn out from the through hole 25 toward the metal fiber sheet 6. The hole diameter of the through hole 25 is not particularly limited, and can be set arbitrarily. The number of the through holes 25 is not particularly limited, and can be set arbitrarily. In the cooling mechanism 8 shown in FIG. 4, the spacing between the through holes 25 is regular, but the through holes 25 may be provided on the upper surface of the support 20 at irregular intervals.

Arrows in FIG. 4 indicate an example of the direction of the flow of the refrigerant introduced into the hollow portion 23 from the open end 21 of the support 20. In the cooling mechanism 8 of the second embodiment, a refrigerant can be introduced from the open end 21 of the support 20 into the hollow portion 23. Therefore, the cooling mechanism 8 of the second embodiment can cool the metal fiber sheet 6 by the coolant drawn out toward the metal fiber sheet 6 from the through hole 25 mainly opened at a portion in contact with the metal fiber sheet 6.
The shape and structure of the support 20 are not particularly limited as long as the refrigerant can be introduced into the hollow portion 23 inside the support 20. When the area of the opening surface of the open end 21 is small and it is difficult to introduce the refrigerant, or when it is desired to improve the cooling efficiency, a refrigerant introducing means for introducing the refrigerant into the hollow portion 23 can be used. Such a refrigerant introducing means is not particularly limited, and includes a known pressurizing means such as a pressurizing pump.

  FIG. 5 is a sectional view taken along line VV of the wiring member 2 of FIG. The arrow in FIG. 5 shows an example of the direction of the flow of the refrigerant derived from the through hole 25. When the refrigerant is introduced into the hollow part 23, the refrigerant flows through the hollow part 23. The refrigerant flowing through the hollow portion 23 is drawn out from the through hole 25 toward the metal fiber sheet 6. The coolant led out from the through holes 25 cools the metal fiber sheet 6. In the metal fiber sheet 6, since the fibers included in the metal fiber sheet 6 are bound at least in part, the refrigerant enters the gap of the metal fiber sheet and is continuously held in the gap, Is efficiently cooled.

By providing the through-hole 25 in the support body 20, the refrigerant can directly reach the metal fiber sheet 6 from the hollow portion 23. Therefore, the cooling mechanism 8 of the second embodiment can sufficiently cool the metal fiber sheet 6 by drawing the refrigerant from the through holes 25. In addition, since the flow rate of the refrigerant can be controlled by adjusting the hole diameter of the through hole 25, the cooling effect of any part that particularly requires cooling can be enhanced.
The coolant that has cooled the metal fiber sheet 6 is derived from the metal fiber sheet 6, but the portion from which the coolant is derived from the metal fiber sheet 6 is not particularly limited, and the upper surface of the metal fiber sheet 6, or the metal fiber It may be derived from the side of the seat 6.

As shown in FIG. 5, a partition 26 is provided inside the support 20. By providing the partition 26 inside the support 20, a plurality of hollow portions 23 that serve as a flow path for the refrigerant are formed inside the support 20.
As shown in FIG. 4, the through-hole 25 is provided on the upper surface of the support 20 along the direction of the partition 26. Therefore, the direction of the refrigerant flowing through the hollow portion 23 is guided by the partition portion 26, and the refrigerant is efficiently led out from the through hole 25. In the wiring member 2 of the second embodiment, the flow rate of the refrigerant flowing through the flow path can be arbitrarily controlled by adjusting the size of the partition 26. Thereby, it is possible to enhance the cooling effect particularly at an arbitrary location requiring cooling.

Specific examples of the material of the first substrate 41 include metal materials such as stainless steel, copper, aluminum, and alumina; polyacrylic resins such as polymethacrylic acid and polycyanoacrylic acid (polycyanoacrylate); polyvinylpyrrolidone resins; Polyester resins such as polyethylene terephthalate; polypropylene resins; fluorine resins such as polytetrafluoroethylene; polyimide resins; polyamide resins containing aramid; polyparaphenylene benzobisoxazole resins.
The organic mold layer 27 is formed from an organic layered material. Examples of the material for the organic layered material include polyvinyl alcohol (PVA) resin; polyacrylic acid resin such as polymethacrylic acid and polycyanoacrylic acid (polycyanoacrylate); polyvinyl pyrrolidone resin; polyester resin such as polyethylene terephthalate; A fluororesin such as polytetrafluoroethylene; a polyimide resin; a polyamide resin containing aramid; a polyparaphenylenebenzobisoxazole resin; a starch; a mannan; a pulp-based material; a non-pulp-based material;

  In step S <b> 2, a through pattern 28 for injecting a casting material is formed in the organic mold layer 27 on the first substrate 41. The penetration pattern 28 can be formed by irradiating the organic mold layer 27 with a laser. In addition to the laser, a punching die, a knife, scissors, an ultrasonic cutter, a cutter, a water jet, or the like can be used. The shape of the penetrating pattern 28 can be set arbitrarily.

In step S3, the casting material 29 is injected into the through pattern 28 formed in step S2 and cured. As shown in FIG. 8, by injecting the casting material 29 into the through pattern 28, the casting material 29 can be cured on the first substrate 41 according to the shape of the through pattern 28. The injection material 29 injected into the through pattern 28 becomes a casting 261 by being cured.
Examples of the casting material include a silicone resin, a fluorine resin, a urethane resin, and an ABS resin. The method for filling the mold with the casting material is not particularly limited, and examples thereof include a filling method using a blade.

At this time, the partition part 26 is formed by laminating the casting 261 and the casting 262. By manufacturing by the method using the casting described above, a cooling mechanism suitable for miniaturization, thinning, and space saving can be obtained without using a mold or the like.

  The height H of the partition 26 shown in step S6 of FIG. 8 is preferably set to 0.5 mm to 5 mm. If the height H of the partition portion 26 is equal to or more than the lower limit value, it becomes easy to introduce the refrigerant. If the height H of the partition portion 26 is equal to or less than the upper limit, the wiring member 2 is easily thinned. The height H of the partition part 26 can be set to an arbitrary height by adjusting the thickness of the organic form layer 27 and the like.

In the wiring member 2 shown in FIGS. 3, 5, and 6, the lower surface of the metal fiber sheet 6 is covered with the support 20, and the side and upper surfaces of the metal fiber sheet 6 are open surfaces. However, the wiring member of the second embodiment is not limited to a form in which the side and top surfaces of the metal fiber sheet 6 are open, and a form in which the side and top surfaces of the metal fiber sheet 6 are not open. There may be. In a mode in which the side surface and the upper surface of the metal fiber sheet 6 are not open surfaces, the refrigerant is not drawn out from the closed surface of the metal fiber sheet 6, and thus is efficiently drawn out to the open surface of the metal fiber sheet 6.

  For example, in the wiring member 2 shown in FIG. 3, instead of the metal fiber sheet 6, the wiring member 1 of the first embodiment described in the section of “[First Embodiment]” may be laminated. In this case, by providing a through hole in the lower surface of the housing 10 of the wiring member 1, the refrigerant introduced from the hollow portion 23 is allowed to pass through the through hole 25 and the lower surface of the housing 10.

(Operation and Effect of Second Embodiment)
In the wiring member 2 according to the second embodiment described above, the support body 20, the metal fiber sheet 6, and the like are cooled by the coolant flowing through the hollow portion 23. Further, since the wiring member 2 of the second embodiment has the partition portion 26, the refrigerant introduced into the hollow portion 23 is easily guided to the flow path formed by the partition portion 26.

The lid 24 can be made of a known metal material, a known ceramic material, a known resin material, or the like. As such a metal material, a ceramic material, and a resin material, the same materials as those described for the support 20 of the second embodiment can be used. As a material of the lid 24, a metal material having high thermal conductivity is preferable from the viewpoint of cooling efficiency.

For example, the metal material can be composed of a copper plate or a copper foil, and the resin material can be composed of a polyester resin, a silicone resin, a fluorine resin, or the like.

  FIG. 10 is a sectional view of the wiring member 3 taken along line XX of FIG. The upward arrow in FIG. 10 indicates an example of the direction of the flow of the refrigerant derived from the through hole 251. When the refrigerant is introduced from the open end 21 of the wiring member 3 into the hollow part 231, the refrigerant flows through the hollow part 231. The refrigerant flowing through the hollow portion 231 is led out of the through hole 251. The coolant led out of the through holes 251 can cool the metal fiber sheet 6.

It is not led out of the member 3. Therefore, the wiring member 3 of the third embodiment can control the flow direction of the refrigerant more easily than the wiring member 2 of the second embodiment, so that the cooling effect can be dramatically improved.
The downward arrow in FIG. 10 shows an example of the direction of the flow of the refrigerant introduced from the through hole 252 into the hollow portion 232. The coolant that has cooled the metal fiber sheet 6 is introduced into the hollow portion 232 through the through hole 252 provided near the through hole 251.

  FIG. 11 is a top view showing the support 20 of FIG. As shown in FIG. 11, a plurality of through holes 251 and 252 are provided on the upper surface of the support 20.

The hole diameters of the through holes 251 and 252 are not particularly limited, and can be set arbitrarily. The number of the through holes 251 and 252 is not particularly limited, and can be set arbitrarily.

In the cooling mechanism 9 of the third embodiment, the refrigerant can be introduced from the opening end 21 into the hollow portion 231, and can be discharged from the through hole 251 toward the metal fiber sheet 6. After that, the refrigerant that has cooled the metal fiber sheet 6 can be introduced into the hollow portion 232 through the through hole 252 and be drawn out from the hollow portion 232.
When the area of the opening surface of the opening end 21 is small and it is difficult to derive the refrigerant, or when it is desired to improve the cooling efficiency, a refrigerant deriving unit that derives the refrigerant from the hollow part 232 can be used. Such a refrigerant deriving unit is not particularly limited, and includes a known depressurizing unit such as a decompressing pump.

The wiring member 3 of the third embodiment can have, in addition to the above-described metal fiber sheet 6, the support 20, and the lid 24, a known configuration of a known wiring member as another configuration. . For example, as an example of another configuration, an insulator covering the metal fiber sheet 6 can be provided. The insulating material is not particularly limited, and includes a known insulating material such as a resin.
In the wiring member 3 shown in FIGS. 9 and 10, the side surface of the metal fiber sheet 6 is an open surface. However, the wiring member of the third embodiment is not limited to the form in which the side surface of the metal fiber sheet 6 is an open surface, and may be a form in which the side surface of the metal fiber sheet 6 is not an open surface. In a mode in which the side surface of the metal fiber sheet 6 is not an open surface, the refrigerant is efficiently led out of the hollow portion 232.

(Operation and Effect of Third Embodiment)
Since the wiring member 3 of the third embodiment described above has the lid 24, it is easy to control the flow direction of the refrigerant. Therefore, the wiring member 3 can be efficiently cooled including the inside of the metal fiber sheet 6 while allowing local cooling. Therefore, the cooling efficiency of the metal fiber sheet 6 is dramatically increased, and the cooling effect of the wiring member 3 is easily excellent. Further, similarly to the wiring member 2 of the second embodiment, the wiring member 3 can be easily reduced in size and thickness, and can be locally cooled.

  FIG. 14 is a perspective view showing the wiring member 5 of the fifth embodiment. As shown in FIG. 14, the wiring member 5 of the fifth embodiment has a metal fiber sheet 6 and cooling mechanisms 8 and 8. In the wiring member 5 of FIG. 14, similarly to the wiring member 4 of FIG. 12, a cooling mechanism 8 is disposed on each of the upper surface and the lower surface of the metal fiber sheet 6. In the wiring member 5, the cooling mechanism 8 has the same configuration as the cooling mechanism 8 described in the wiring member 2 of the second embodiment.

[Sixth embodiment]
Hereinafter, a wiring member 50 according to a sixth embodiment of the present invention will be described. In the wiring member 50 of the sixth embodiment shown in FIGS. 16 to 18, the wiring member 1 of the first embodiment, the wiring member 2 of the second embodiment, the wiring member 3 of the third embodiment, and the wiring member 3 of the fourth embodiment. The same components as those of the wiring member 4 and the wiring member 5 of the fifth embodiment are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 16 is a top view of the wiring member 50 of the sixth embodiment. FIG. 17 is a cross-sectional view along XVII-XVII of the wiring member 50 according to the sixth embodiment. FIG. 18 is a side view of the wiring member 50 of the sixth embodiment.
As shown in FIGS. 17 and 18, the wiring member 50 of the sixth embodiment has a metal fiber sheet 6 and a cooling mechanism 53.
The cooling mechanism 53 has a first metal layer 51, a second metal layer 52, and a refrigerant introduction unit (not shown).
As shown in FIG. 17, the first metal layer 51 is a layer in contact with the first surface A of the metal fiber sheet 6. In the wiring member 50, the first surface A is the upper surface of the metal fiber sheet 6. The second metal layer 52 is a layer in contact with the second surface B of the metal fiber sheet 6. In the wiring member 50, the second surface B is the lower surface of the metal fiber sheet 6 and is a parallel surface facing the first surface A. Thus, the metal fiber sheet 6 is sandwiched between the first metal layer 51 and the second metal layer 52.

The first metal layer 51 and the second metal layer 52 may be a metal plate or a metal foil. The type of the material of the metal plate or the metal foil is not particularly limited. The details and preferred embodiments of the material of the metal plate or the metal foil are the same as those described for the material of the metal fiber sheet 6.
The material of the first metal layer 51 and the material of the second metal layer 52 may be different from each other or may be the same.

The thicknesses of the first metal layer 51 and the second metal layer 52 are not particularly limited. From the viewpoint of flexibility of the wiring member 50, the thickness of the first metal layer 51 is preferably from 18 to 500 μm, and the thickness of the second metal layer 52 is preferably from 100 to 5000 μm.
When the thickness of each of the first metal layer 51 and the second metal layer 52 is equal to or more than the above lower limit, the durability of the wiring member 50 is improved. When the thickness of each of the first metal layer 51 and the second metal layer 52 is equal to or less than the above upper limit, the wiring member 50 is excellent in flexibility.
The thickness of the first metal layer 51 and the thickness of the second metal layer 52 may be different from each other or may be the same.

In the wiring member 50, the first metal layer 51 is a metal foil, and the second metal layer 52 is a metal plate. In this case, as the metal foil (first metal layer 51), a copper foil or an aluminum foil is preferable, and a copper foil is more preferable. And as a metal plate (2nd metal layer 52), a copper plate or an aluminum plate is preferable, and a copper plate is more preferable.
In the wiring member 50, the thickness of the first metal layer 51 (metal foil) is larger than the thickness of the second metal layer 52 (metal plate). In this case, in consideration of the durability, flexibility, and ease of processing of the wiring member 50, the thickness of the first metal layer 51 (metal foil) is preferably 18 to 500 μm. The thickness of the second metal layer 52 (metal plate) is preferably 100 to 500 μm.
As described above, when the first metal layer 51 is a metal foil and the second metal layer is a metal plate, the wiring member 50 is more excellent in flexibility, and the processing of the wiring member 50 is further facilitated.
In the wiring member 50, the first metal layer 51 and the second metal layer 52 are parallel to each other, but the present invention is directed to a mode in which the first metal layer 51 and the second metal layer 52 are parallel to each other. It is not limited to.

The coolant introducing means (not shown) is not particularly limited as long as the coolant can be directly introduced into the metal fiber sheet 6. As a specific example of such a refrigerant introduction unit, the same as the refrigerant introduction unit described in the first embodiment can be mentioned.
As described above, since the cooling mechanism 53 includes the first metal layer 51, the second metal layer 52, and the coolant introducing means (not shown), the coolant is introduced into the gap of the metal fiber sheet 6 so that the metal fiber sheet 6 Can be cooled.

As described above, in the wiring member 50, the metal fiber sheet 6 is sandwiched between the first metal layer 51 and the second metal layer 52. Therefore, it can be said that the wiring member 50 is a laminate having the metal fiber sheet 6, the first metal layer 51, and the second metal layer 52. Since the metal fiber sheet 6 is a sheet-like flexible material, such a laminate has excellent workability. Therefore, by preparing the wiring member 50 (laminated body) having a relatively large size in advance, the wiring member 50 can be used as a wiring member of an arbitrary shape and a precursor (base material) of a wiring member of an arbitrary size. . That is, the wiring member 50 can be used as a base material when the size is relatively large.
Such a base material may be used, for example, by forming a plurality of grooves in the surface of the metal layer by processing and arbitrarily deforming the surface of the metal layer as described in a seventh embodiment described later. As in the eleventh embodiment of the present invention, the present invention may be used for the manufacture of relatively finely divided wiring members. That is, such a base material can be used as a laminate for manufacturing a wiring member having an arbitrary shape and size.

(Operation and Effect of Sixth Embodiment)
Since the wiring member 50 of the sixth embodiment includes the metal fiber sheet 6 and the cooling mechanism 53, the wiring member 50 has an excellent cooling effect. The wiring member 50 of the sixth embodiment can be used as a precursor of a wiring member of any shape and a wiring member of any size.

In the wiring member 54, a plurality of grooves 57 are formed on the surface of the first metal layer 56. The shape of the groove 57 is not particularly limited. The number of grooves may be one or more. The position on the surface of the first metal layer 56 where the groove 57 is formed is not particularly limited, and can be formed, for example, in accordance with the position of a desired coolant flow path.

As shown in FIG. 20, in the wiring member 54, the metal fiber sheet 6 is divided into regions C1, C2, and C3 by a plurality of grooves 57. The regions C1, C2, and C3 of the metal fiber sheet 6 divided into a plurality function as coolant flow paths.
Since the cooling mechanism 55 has the first metal layer 56, the second metal layer 52, and a refrigerant introduction unit (not shown), the cooling mechanism 55 introduces the refrigerant into the gaps between the regions C1, C2, and C3 of the metal fiber sheet 6. The metal fiber sheet 6 can be cooled effectively. The flow paths in the regions C1, C2, and C3 may be completely shut off, or may be narrowed by the grooves 57.

When the groove 57 is formed, an external force is applied to the surface of the first metal layer 51 on the upper surface of the wiring member 50, so that the first metal layer 56, the metal fiber sheet 6, and the second metal layer 52 are separated. It may be fixed and joined in this order. As a method of applying an external force to the surface of the first metal layer 51, pressure or driving may be used, and any molding method can be applied.
Before forming the groove 57, the wiring member 50 may be cut into a desired size, and after adjusting the size, the groove 57 may be formed.

(Operation and Effect of Seventh Embodiment)
Since the metal fiber sheet 6 between the regions C1, C2, and C3 is bound, the number of voids is relatively small and the size of the voids is also small. Therefore, the refrigerant introduced into each of the regions C1, C2, and C3 of the metal fiber sheet 6 hardly passes through the portion of the metal fiber sheet 6 fixed by the groove 57. As a result, according to the wiring member 54, the cooling effect of the metal fiber sheet 6 in each of the regions C1, C2, and C3 is further enhanced as compared with the wiring member 50 of the sixth embodiment. Furthermore, by introducing a refrigerant into the gaps between the regions C1, C2, and C3 of the metal fiber sheet 6, the regions C1, C2, and C3 of the metal fiber sheet 6 can be locally cooled.

As described above, according to the wiring member 54, the first metal layer 56 and the second metal layer 52 at the portions in contact with the regions C1, C2, and C3 of the metal fiber sheet 6 can be locally cooled. For example, the refrigerant may be simultaneously introduced into all of the plurality of regions C1, C2, and C3, and the refrigerant may be selectively introduced into at least one of the plurality of regions C1, C2, and C3. You may.
The position where the groove 57 is formed can be changed as appropriate. By changing the position where the groove 57 is formed, the positions of the metal fiber sheet 6, the first metal layer 56, and the second metal layer 52 that are locally cooled can be changed. As described above, one of the features is that the wiring member 54 has a high degree of freedom in design.

A part 67 is formed. In the wiring member 63, portions of the metal fiber sheet 6 separated by the crimping portions 67 at both ends function as a flow path for the refrigerant.
Since the cooling mechanism 64 has the first metal layer 65, the second metal layer 66, and a refrigerant introducing unit (not shown), the refrigerant is supplied to the gaps between the two ends of the metal fiber sheet 6 separated by the crimping portions 67. By introducing, the metal fiber sheet 6 can be cooled effectively.

In the wiring member 72, portions of the metal fiber sheet 6 separated by the joints 76 at both ends function as flow paths for the refrigerant.
Since the cooling mechanism 73 has the first metal layer 74, the second metal layer 75, and a refrigerant introduction unit (not shown), the refrigerant is supplied to the gaps of the metal fiber sheet 6 at the portions separated by the joints 76 at both ends. By introducing, the metal fiber sheet 6 can be cooled effectively. Note that, also in the wiring member 72, the configuration that functions as a flow path for the refrigerant is not necessarily limited to the sheet-like form.

In the wiring member 72, similarly to the wiring member 68 of the tenth embodiment, a partition section for dividing the metal fiber sheet 6 into a plurality of regions may be provided in the second metal layer 75.

(Operation and Effect of Eleventh Embodiment)

By using a plurality of wiring members 72, it is possible to locally cool a portion to be cooled.
In particular, since the metal fiber sheet 6 is a flexible material, the wiring member 72 has excellent flexibility. Therefore, the wiring member 72 can be easily applied to a surface other than a flat surface such as a curved surface or an uneven surface.

The metal layer 80 is provided on the lower surface of the metal fiber sheet 6 in contact with the lower surface of the metal fiber sheet 6.
The material of the resin layer 79 is not particularly limited as long as flexibility is ensured. From the viewpoint of flexibility, the thickness of the resin layer 79 is preferably 0.5 to 5 mm, more preferably 0.8 to 4 mm, and still more preferably 1 to 3 mm. When the thickness of the resin layer 79 is equal to or larger than the lower limit, the production of the wiring member 77 is easy. When the thickness of the resin layer 79 is equal to or less than the upper limit, the flexibility of the wiring member 77 is further improved.
The width of the resin layer 79 is the same as the width W of the second metal layer 75 described above, and the preferred embodiment is also the same.

At both ends of the wiring member 77, the resin layer 79 and the metal layer 80 are joined. In the wiring member 77, the portion of the metal fiber sheet 6 between the resin layer 79 and the metal layer 80 functions as a coolant flow path.

Note that, also in the wiring member 77, the configuration that functions as a coolant flow path is not necessarily limited to a sheet-like configuration. That is, in the wiring member 77, the configuration functioning as a coolant flow path may be a form of a prismatic metal fiber body.

  The wiring member 77 is formed, for example, by cutting the respective base materials of the resin layer 79 and the metal layer 80 into a desired size, cutting the metal fiber sheet 6 into a desired size, and placing the metal fiber sheet 6 on the metal layer 80. Can be manufactured by disposing the resin layer 79 on the upper surface of the metal fiber sheet 6 in a state where is disposed.

(Operation and Effect of Twelfth Embodiment)
Since the width of the wiring member 77 is relatively shorter than that of the wiring member 63 of the ninth embodiment, the wiring member 77 can be suitably applied to electric equipment and electronic equipment that are required to be reduced in size and thickness.
Since the metal fiber sheet 6 and the resin layer 79 are flexible materials, the wiring member 77 is more excellent in flexibility than the wiring member 72. Therefore, the wiring member 77 can be more easily applied to a surface other than a flat surface such as a curved surface or an uneven surface than the wiring member 72.
