초록

In a small-sized computer of a natural air-cooling type, a high-temperature radiator promotes natural convection so as to increase a quantity of heat radiation and to raise the allowable limit of heat generation of LSI chips, thereby improving the processing speed of the computer. For this purpose, a casing and fins are utilized as heat radiators at relatively low temperatures of about 40°C. which are safe even if they are touched by an operator\s hands. On the other hand, the high-temperature radiator set at about 50°to 60°C. is provided inside of the c...
