Abstract

PURPOSE:To enable heat releasing electronic equipments used for a car to be effectively cooled off by arranging a heat pipe between the heat releasing electronic equipments and a carburetor in such a manner that a heat accumulator is placed at the electronic equipment side and a heat radiator is in the carburetor side. CONSTITUTION:A heat pipe 3 is arranged between a housing 2 with heat releasing electronic equipments and a carburetor 6. Heat released from the electronic equipments 1 is concentrated on a heat accumulator of the heat pipe 3 arranged in the housing 2, then is dissipated from a heat radiator 5 in the heat pipe 3 arranged at an air intake duct 7 of the carburetor 6. This configuration enables the electronic equipmentw 1 to be effectively cooled off allowing the 1 to be compactly arranged. Also as the radiator 5 of the heat pipe 3 is arranged in a space of the carburetor 6, the efficiency of radiation can be impoved and the air inducted to the carburetor 6 can be pre-heated as well.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cooling device for automotive electronic equipment.

[Conventional technology]

Conventionally, electronic devices built into automobiles have electronic control, etc., which have been applied only to a relatively limited range, and the amount of heat generated is relatively small. Natural wind cooling is performed.

However, as electronic controls have come to be used in various parts of automobiles, electronic devices have become more compact. There are limits to this.

[Problem that the invention seeks to solve]

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, 1.
The object of the present invention is to provide an efficient cooling device for automotive electronic equipment.

[Means for solving problems]

In order to achieve the above object, the present invention uses a heat pipe to extract the heat generated by the electronic equipment for the automobile, and cools the heat in a part of the carburetor.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which a pipe 6 is arranged between a casing 2 incorporating an electronic device 1 and a carburetor 6, and heat generated by the electronic device 1 is transferred into the casing 2. The heat is collected in the heat receiving part 4 of the heat pipe placed in the air, and is emitted from the heat radiating part 5 of the heat pipe placed in the air intake lower part of the carburetor 6.

FIG. 2 shows another example in which the heat receiving part 4 of the heat vibro is connected to a heat generating electronic component 8°8Z Brt mounted on the electronic device 1.
This is the case, for example, when they are brought into contact via an electrically insulating sheet 9 with excellent thermal conductivity, which is made of synthetic rubber containing an inorganic filler such as alumina or boron nitride. If the heat receiving part 4 is brought into contact with the heat generating part as in this example, the electronic device 1 can be efficiently cooled, which is effective for electronic devices using electronic components that generate a large amount of heat.

〔Effect of the invention〕

As described above, by cooling automobile electronic equipment with a heat pipe, cooling can be performed efficiently and the electronic equipment can be made compact. In addition, since the heat dissipation part is installed in the hollow part of the carburetor, there is no need for a fan for heat dissipation due to the air flow, and it also preheats the air taken into the carburetor, which improves engine efficiency. Connect,
There are other advantages as well.
