To improve the cooling efficiency. Here, in the case of this known example, the cooling fan 17 blows air to the fins 11, 11, 11... Mounted in the lateral direction from the lateral direction indicated by the arrow in FIG.

As the air rises, cool air is supplied from below the cooling panels 1, 1, 1,... To promote heat transfer. The greater the amount of air that rises, the greater the amount of heat radiation (heat transfer), and the cooling performance Goes up.

得ず、いずれにしても不都合である。In the above-mentioned known example, a vertical ventilation hole 18 is provided in each of the fins 11 in order to solve this disadvantage. However, when the ventilation hole 18 is a small hole, the resistance due to the horizontal fin 11 is large, and the improvement is achieved. However, if the number of holes is small, the amount of ventilation cannot be secured. On the other hand, if the hole diameter and the number of holes are increased in order to secure a natural ventilation amount comparable to that of the conventional finless radiator, the area of each fin 11 itself becomes small, and there is no point in attaching the fins. When the interval of 1... Is increased, the radiator 9 becomes large, the installation area increases, and the cooling panel 1,
When the number of 1, 1,... Is reduced, the heat radiation area is reduced and the heat radiation amount is reduced. Therefore, in the above-mentioned known example, when using the self-cooling type, the heat radiation amount is further reduced as compared with the conventional finless radiator, and in order to avoid this, the size must be increased, which is inconvenient anyway.
