2. Description of the Related Art Generally, a heat sink device for a heating element is
As shown in FIG. 2A, a plurality of heat radiation fins 3 are formed upright on a base plate 2, and the surface area of the heat radiation portion (contact area with the base plate 2) is smaller than that of the base plate 2, and the heating element 1 is provided. When cooling the base plate 2, since it is effective to immediately transfer the heat generated from the heat generating element 1 to all the radiation fins 3 and to radiate the heat from the radiation fins 3 in order to improve the cooling efficiency, Is thickened to promote heat diffusion in the base plate 2.

However, in the above-mentioned conventional example, since the thickness of the base plate 2 is large, the cooling air introduced into the housing of the apparatus is as shown by an arrow A in FIG. 2 (a). After hitting the front end (windward side edge) of the base plate 2 and escaping upward, the cooling air does not reach the heat radiation fin region directly above the element, and the upward flow generated at the front end flows in the direction of the heat radiation fin 3. Since it becomes a resistance element against the cooling air parallel to the mounting board,
There is a drawback in that the amount of air blown into the space decreases and the overall cooling efficiency decreases.

In the present invention, when the inclined surface 4 formed on one side edge of the base plate 2 is arranged so as to face the windward side of the cooling air, the cooling air A is supplied to the base plate 2 as shown in FIG. 2 (b). Without colliding with the front end, it gently rises along the inclined surface 4 and is guided between the heat radiation fins 3. As a result, the cooling air is guided between the radiating fins 3 without being obstructed by the turbulent flow generated by the collision at the front end, so that the cooling efficiency is improved.

On the other hand, the radiating fin 3 is essential for radiating the heat absorbed from the heating element 1, but on the other hand, it functions as a pressure loss element for the cooling air, which causes a reduction in the flow velocity. The present inventor has conceived the design of a heat sink device that also takes into consideration the negative side by providing the radiation fin 3, which has not been considered in the past, and reached the following conclusions.

That is, it is generally said that by increasing the number of the heat radiation fins 3, the heat radiation area becomes larger and the heat radiation capacity becomes higher. However, by providing a large number of the heat radiation fins 3 in a certain area, the wind velocity of the cooling air can be increased. As a result, the amount of cooling air that passes through the radiating fins 3 per unit time decreases, and the cooling air amount tends to decrease.

On the other hand, if the radiation fins 3 are reduced, the radiation area is reduced, but the cooling air velocity can be expected to improve due to the pressure loss reduction, and the cooling air volume per unit time increases.

FIG. 2 (c) is a conceptual diagram showing the influence on the cooling performance by disposing the radiation fins 3. For example, as shown in FIG. 1 (a), there are a plurality of stages in the cooling air flow direction. When the radiating fins 3 are arranged, the change of the cooling performance is shown when one row of the radiating fins 3 on the front row (upwind) side is removed within a predetermined length range. In the figure, the upward curve is
It is shown that the contribution to the cooling performance is increased by increasing the length of removing the heat radiation fin 3 (flat portion length-horizontal axis).

On the other hand, the downward-sloping curve in the figure shows the deterioration of the cooling performance due to the wind speed which decreases as the heat radiation area (horizontal axis) increases. The cooling performance is the product of the heat radiation area and the cooling air volume. From a qualitative point of view, it can be expected that the maximum cooling performance is exhibited in the vicinity of the intersection of the above-mentioned two curves.
