BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for a heating element such as a semiconductor element used in a power supply device for a vehicle.

[0002]

2. Description of the Related Art FIG. 30 and FIG.
Issued on May 25, Meiden Hourly Report No. 2. Outline of the conventional configuration of a cooling device of a forced-cooling type heating element using a fan described in Vol. 2, No. 175 (March / April 1984, pp. 34 to 36). is there. FIG. 30 is a front sectional view, and FIG. 31 is a side sectional view. In each of these figures,
Reference numeral 1 denotes a heating element (hereinafter, referred to as a semiconductor element) including a semiconductor element such as a thyristor or a transistor, which is a rectifying element or the like in a vehicle power supply device. It is a metal block having a heat sink function, and is made of a metal having good heat conductivity such as copper and aluminum to derive heat generation of the semiconductor element 1. Reference numeral 3 denotes a plurality of holes formed in the metal block 2, for example, holes formed in the vertical direction from the upper surface of the metal block 2 to a predetermined depth. Reference numeral 4 denotes a working fluid 5 such as water, ammonia, or the like, which is sealed in each of the insides. The plurality of heat pipes extend vertically above the metal block 2 and guide heat generated by the semiconductor element 1 to the outside. Reference numeral 8 denotes a radiating fin provided integrally with the heat radiating side 7 of each heat pipe 4, and each of the heat radiating surfaces is provided in a horizontal direction, and 9 is provided so as to cover the other side 7 of each heat pipe 4. The wind tunnel 10 is a fan that supplies forced cold air into the wind tunnel 9. The working fluid 5 is always located on one side 6 of the heat pipe 4.

Next, the operation will be described. Semiconductor element 1
The heat generated at the hole 3 is transmitted to the metal block 2 and the hole 3
The heat is transmitted to one side 6 of each heat pipe 4 via the wall surface, and is transmitted to the working fluid 5 sealed therein. As a result, the working fluid 5 boils and evaporates into vapor, and moves from one side 6 of the heat pipe 4 to the other side 7 of the heat pipe 4 through the inside. The vapor of the working fluid 5 that has moved from one side 6 of the heat pipe 4 located below to the other side 7 of the heat pipe 4 located above is cooled by cooling air supplied from a fan 10, and the other side of the heat pipe 4 The heat of the working fluid 5 is condensed by heat exchange on the side 7 wall.
Liquefy. The heat exchanged on the wall on the other side 7 of the heat pipe 4 moves to each radiating fin 8 and is cooled by the cooling air forcedly sent by the fan 10, and the heat is transferred from the radiating fin 8 to the surrounding air. Dissipate heat. The condensed and liquefied working fluid 5 travels to the inner wall surface of the heat pipe 4 and returns to one side 6 of the heat pipe 4. By such natural repetition of the operation, the heat generated in the semiconductor element 1 is transported from the one side 6 to the other side 7 of the heat pipe 4 via the metal block 2 and cooled by the forced cooling air from the fan 10. ing.

[0004]

However, in the above-described conventional apparatus, there is a case where the forced supply of the cooling air is stopped due to the stop due to the failure of the fan 10 or the like. That is, the air heated by the other side 7 of the heat pipe 4 may expand due to a rise in temperature and tend to rise in the vertical direction by natural convection. Since the air is prevented from moving upward by the upper radiation fins 8, the heated air stays between the radiation fins 8. Therefore, the cooling capacity is significantly reduced due to an increase in the temperature of the air around the radiation fins 9, and the heat generated in the semiconductor element 1 cannot be sufficiently removed, and the semiconductor element 1 is overheated. Therefore, there is a problem that the power supply device itself such as a thyristor power supply has to be stopped. If the same cooling performance is to be obtained in a state where the forced supply of the cooling air by the fan 10 is stopped or in a state where the fan 10 is not provided, the radiation fins are remarkably large in order to secure a contact area with the air. There is a need to.
Therefore, there is a problem in that when this device is incorporated in another product, it occupies a considerable space and the product itself becomes large. In addition, when used as a cooling device for a heating element such as an in-vehicle power supply device, the cooling capacity in a natural air cooling state when the vehicle is stopped, the vibration resistance to the vibration due to the roll of the vehicle, the measures against the vibration noise accompanying the There is also a problem that the environmental resistance of the heat radiating part exposed to the air is insufficient. In order to improve the cooling capacity of the heating element, it is conceivable to incline the entire cooling device including the metal block 2, the heat pipe 4, and the radiation fins 8 in the horizontal direction. In this case, the radiating fins 8 are inclined, and the cooling capacity is increased by the amount that the heated air does not stay between the radiating fins 8. The flow becomes worse due to friction with the fins 8, and the effect of the cooling capacity cannot be expected much. Further, as a decisive problem in this case, since the entire cooling device is inclined in the horizontal direction, it is necessary to secure an installation space having a large area. There is a problem that is inferior.

The present invention has been made to solve the above-mentioned problems, and has a cooling capacity by natural air cooling.
An object of the present invention is to provide a cooling device for a heating element having excellent vibration resistance.
