Description

  The present invention relates to a conductor and a heat dissipation structure for the conductor.

For example, as a shield conductor mounted on a vehicle such as an electric vehicle, a plurality of non-shielded wires are collectively surrounded by a shield member made of a cylindrical braided wire obtained by knitting metal fine wires in a mesh shape. A shielding structure is considered. As a method for protecting the shield member and the electric wire in this type of shield conductor, generally, a means for surrounding the shield member with a protector made of synthetic resin is used, but there is a problem that the number of parts increases when the protector is used.
Therefore, the applicant of the present application has proposed a structure in which a non-shielded electric wire is inserted into a metal pipe as described in Patent Document 1. According to this structure, since the pipe exhibits the function of shielding the electric wire and the function of protecting the electric wire, there is an advantage that the number of parts can be reduced as compared with the shield conductor using the shield member and the protector.
JP 2004-171952 A

In shield conductors using pipes, there is an air layer between the wires and the pipe, so the heat generated in the wires when energized is blocked by the air with low thermal conductivity and is not easily transmitted to the pipes. Since the pipe does not have an external ventilation path such as a gap between stitches in the braided wire, the heat generated in the electric wire tends to be trapped inside the pipe and the heat dissipation tends to be low.
Here, the amount of heat generated when a predetermined current flows through the conductor decreases as the cross-sectional area of the conductor increases, and the temperature rise value of the conductor due to heat generation is suppressed as the heat dissipation of the conductive path increases. Therefore, in an environment where an upper limit is set for the temperature rise value of the conductor, in the case of a shield conductor with low heat dissipation efficiency as described above, it is necessary to increase the cross-sectional area of the conductor to suppress the amount of heat generation.
However, increasing the cross-sectional area of the conductor means that the shield conductor is increased in diameter and weighted, and a countermeasure is desired.

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3. An engine room is provided in the front part of the vehicle body Bd of the electric vehicle EV. In the engine room, a device Ma (for example, an inverter) that constitutes a power circuit for driving the travel motor Mo and an engine for driving gasoline. Eg is housed. A device Mb (for example, a battery) constituting a power circuit is mounted on the rear portion (for example, a trunk room) of the vehicle body Bd. Between the two devices Ma and Mb, a shield conductor Wa (conductor which is a constituent element of the present invention) and an in-vehicle conductor Wb are routed.

  The shield conductor Wa has a configuration in which three heat pipes 10 are inserted into a shield pipe 20 made of metal (for example, aluminum alloy, stainless steel, copper, copper alloy, etc.) having both a collective shield function and a conductor protection function. . The heat pipe 10 is made of a metal pipe having both ends closed, and has a known structure in which a working fluid (not shown) is sealed in an internal airtight space 11. A synthetic resin is formed on the outer periphery of each heat pipe 10. An insulating coating 12 is provided.

  The front and rear end portions of the three heat pipes 10 protrude to the outside of the shield pipe 20, and the connection member 13 is fixed to the protruding portions so as to be conductive by cold pressure welding or the like. The connecting member 13 is formed with an open barrel-shaped crimping portion 14. In addition, outside the shield pipe 20, a substantially half region on the tip side of the heat pipe 10 is in a state where the insulating coating 12 is removed and exposed. The exposed portion of the front end portion of the heat pipe 10 (the portion disposed outside the shield pipe 20) releases the heat generated by the heat pipe 10 when the heat pipe 10 is energized. It has become.

  The shield conductor Wa is routed substantially horizontally along the under floor of the vehicle body Bd (below the floor plate Fp). At the front end portion of the shield conductor, the front end portion of the shield pipe 20 is fixed in a suspended state to the vehicle body Bd by the bracket 21, and the heat pipe 10 protruding from the shield pipe 20 is attached to the floor plate Fp by the mounting member 30. It is fixed to the outer surface (lower surface). On the other hand, at the rear end portion of the shield conductor Wa, the shield pipe 20 is fixed to the lower surface of the floor board Fp by the bracket 21 in a suspended state.

Next, the attachment member 30 will be described.
The attachment member 30 includes a heat transfer member 31, a fixture 33 and a bolt 37.
The heat transfer member 31 has elasticity capable of exhibiting vibration absorption performance (buffer performance) and is made of a material having high thermal conductivity (for example, synthetic resin such as silicon rubber). The heat pipe 10 and the insulating coating 12 are formed into a substantially rectangular shape by molding so as to collectively surround the heat pipe 10 and the insulating coating 12. Specifically, ribs 32 that protrude from the left and right side edges of the heat transfer member 31 along the upper surface are formed integrally over the entire length of the heat transfer member 31. From the front end surface (the left end surface in FIG. 2) of the heat transfer member 31, the front end portion of the heat pipe 10 protrudes in an exposed state, and the connecting member 13 is fixed to the tip of the protruding portion. On the other hand, between the rear end face of the heat transfer member 31 and the front end of the shield pipe 20, the heat pipe 10 surrounded by the insulating coating 12 is exposed.

  The fixing member 33 is made of a metal plate, and has a substantially “U” -shaped covering portion 34 that is in surface contact with the lower surface of the heat transfer member 31 and the left and right side surfaces, and the lower surface of the rib 32 extending from the left and right edges of the covering portion 34. A pair of left and right support plate portions 35 in surface contact with each other, and a plate-like fin 36 extending from the outer surface of the cover portion 34 at a substantially right angle. A metal bolt 37 is passed through the support plate portion 35 of the fixture 33 from below. The bolt 37 penetrates the rib 32 of the heat transfer member 31 and is screwed into a female screw portion (not shown) of the floor board Fp. By fastening the bolt 37, the fixture 33, the heat transfer member 31, and the heat pipe 10 are fixedly attached to the vehicle body Bd (floor plate Fp). The rear end portion of the fixture 33 and the front end portion of the shield pipe 20 are electrically connected via a shield member (not shown) that collectively surrounds the heat pipe 10 surrounded by the three insulating coatings 12. Connected as possible.

  The in-vehicle conductor Wb encloses three flexible non-shielded electric wires 40 with a flexible shield member (not shown) made of a braided wire obtained by knitting a fine metal wire. It is connected to both front and rear ends of the shield conductor Wa. That is, the core wire 42 exposed by peeling off the resin coating 41 at the terminal portion of the electric wire 40 of the in-vehicle conductor Wb is fixed to the crimping portion 14 of the connecting member 13 of the shield conductor Wa so as to be conductive by crimping. . Further, at the front end portion of the shield conductor Wa, the front end portion of the fixture 33 and the end portion of the flexible shield member of the in-vehicle conductor Wb are connected so as to be conductive, and the rear end of the shield conductor Wa. In the section, the end of the flexible shield member of the in-vehicle conductor Wb is connected to the rear end of the shield pipe 20 so as to be conductive.

Next, the operation of this embodiment will be described.
When the heat pipe 10 as a conductor is energized, the heat pipe 10 generates heat, the heat pipe 10 becomes hot inside the shield pipe 20, and the heat radiating portion 15 of the heat pipe 10 located outside the front of the shield pipe 20 is a low temperature portion. Therefore, a temperature gradient is generated between the inside of the shield pipe 20 and the heat radiating portion 15. Then, the working fluid in the heat pipe 10 evaporates inside the shield pipe 20 to absorb latent heat, the vapor moves toward the heat radiating portion 15, the vapor condenses in the heat radiating portion 15 and releases latent heat, Return to the high temperature side as hydraulic fluid. By repeating this, the heat in the shield pipe 20 moves to the heat radiating portion 15.

  The heat that has moved to the heat radiating portion 15 is transmitted from the outer surface of the heat radiating portion 15 to the heat transfer member 31, and moves inside the heat transfer member 31. The heat transferred to the upper surface of the heat transfer member 31 is transferred to the metal floor plate Fp and spreads from the floor plate Fp to the entire vehicle body Bd. Further, the heat that has moved to the lower surface and the left and right side surfaces of the heat transfer member 31 is transmitted to the fixture 33 and dissipated from the surface of the fixture 33 into the atmosphere, and also moved from the fixture 33 to the fin 36 to move to the fin 36. Is emitted from the surface of the atmosphere into the atmosphere.

  As described above, in this embodiment, the heat pipe 10 having a heat dissipation function is also used as a conductor. In other words, the conductor itself was provided with a heat dissipation function. And the part arrange | positioned outside the shield pipe 20 among the heat pipes 10 functions as the heat radiating part 15, and the heat generated by energizing the heat pipe 10 that is a conductor is released in the heat radiating part 15. ing. Therefore, heat generated by energization does not accumulate in the shield pipe 20 and heat dissipation efficiency is good.

  Further, paying attention to the fact that the vehicle body Bd of the automobile can be used as a heat absorber and a heat radiator having a large heat capacity, the heat radiation portion 15 of the heat pipe 10 is attached to the floor plate Fp of the vehicle body Bd. In the state where the heat radiating part 15 is attached to the vehicle body Bd, the heat dissipation performance of the heat absorbing performance of the vehicle body Bd maintains the temperature gradient between the heat radiating part 15 and the vehicle body Bd, and heat is efficiently transmitted from the heat radiating part 15 to the vehicle body Bd side. Is transmitted to. Therefore, the heat radiation efficiency is better than the means for releasing the heat of the heat radiation portion 15 into the atmosphere.

Further, since the heat transfer member 31 having a bufferable elasticity is interposed between the heat radiating portion 15 and the floor plate Fp of the vehicle body Bd, the heat radiating portion 15 (the heat pipe 10 or the shield conductor Wa) from the vehicle body Bd side. The transmitted vibration can be reduced.
Further, since the heat pipe 10 is used not only as a heat radiating means but also as a conductor, it is superior in space efficiency as compared with a mode in which the conductor and the heat pipe are separately arranged.

Arranged. In a state where the heat radiating unit 15 is disposed facing the heat radiating port 55, the heat of the heat radiating unit 15 is released into the atmosphere through the heat radiating port 55 due to a temperature difference between the inside of the housing 51 and the atmosphere. According to the second embodiment, heat generated by energization is not trapped in the casing 51, so that heat dissipation efficiency is good.
Moreover, in the second embodiment, since the fan 57 that generates the air flow from the inside of the casing 51 toward the atmosphere outside the casing 51 is provided in the heat dissipation port 55, the heat dissipation efficiency is high.
