摘要 |
In a portable personal computer in which high-exothermic devices are mounted within a flat case equipped with an input unit, the and in which a surface temperature of the exothermic devices and the input unit is cooled down to or below a predetermined temperature. A first space is created between the back of a keyboard operating section and an electronic circuit board 3, the electronic circuit board 3 is installed so that the face thereof on which the high-exothermic devices are mounted faces away from the back of the keyboard, a second space is created between the electronic circuit board 3 and an electronic circuit board 2, and a fan 4 is installed inside the case so that cooling air flows from the first space to the second space. A flow path for circulating outside air into the case via an air intake hole 8 is constructed on the wall of the input device operating section.
