ことができないという欠点があった。In the conventional forced air cooling radiator described above, the housing exterior is heated by the air current heated by the power transistor 4. Since the case exterior may be directly touched by the user's hand, it is necessary to keep the temperature within the range of the standard. Therefore, there is a disadvantage that the radiator cannot be downsized.

FIG. 1 is a perspective view showing a forced air cooling radiator according to an embodiment of the present invention. The radiator body 1 shown in the figure is formed in a rectangular cylindrical shape, and a power transistor 4 is adhered to an outer surface thereof in close contact. The fan 2 is attached to one opening of the radiator body 1 and the other opening communicates with the opening of the back panel. Vent holes 3, 3,... Are provided near the air flow outlet of the radiator.

る。The air flows as shown by the arrows in the figure and is exhausted to the outside of the housing so as not to stay inside the housing. The exhaust contains cold air sucked by the airflow of the fan 2 from the ventilation holes 3, 3,..., And its temperature is low so that the rear panel is not heated. The temperature of the part can be suppressed within the range of the standard.

る。FIGS. 2 and 3 show a forced air-cooled radiator according to another embodiment of the present invention. In this embodiment, a cover 5 is provided near the air flow outlet of the radiator body 1 to which the power transistor 4 is attached, and air flows as shown by arrows in the figure. That is, the air flow sent by the fan 2 sucks air from between the cover 5 and the radiator body 1, and the air sent by the fan 2 and the air entered from between the cover 5 and the radiator body 1 are mixed. It is exhausted outside the body. This embodiment also has the same effect as the embodiment described in FIG.

冷却効率が高くなり放熱器を小型にすることができる。According to the forced air-cooled radiator of the present invention, the temperature of the exhaust from the radiator drops, and the exhaust does not heat the radiator through the rear panel, so that the cooling efficiency of the radiator is high. The radiator can be downsized.
