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...
A portable computer having an air natural convection and heat radiation structure including computer component parts which generate heat and are provided in a casing, wherein a high-temperature radiator is heat-conductively connected to said heat generating computer component parts via a heat-conductive member inside said casing, a low-temperature radiator is formed by at least one part of said casing thermally connected to said high-temperature radiator, an air passage in said casing is formed between said high-temperature radiator and said low-temperat...
