PROBLEM TO BE SOLVED: To provide an electronic device which has an outer enclosure for heat radiation. SOLUTION: An outer enclosure includes at least one unit which is built in heat-conducting inner housings 4 and 6 which provide RF(radio frequency) shielding, are brought into contact with the outer enclosure so as to transmit heat to each other and are placed on the wall 7 of the outer enclosure. The wall 11 of the unit has a 1st recess 14 for housing the evaporation device 13 of a heatpipe. The heatpipe is fixed between the outer enclosure and the inner housing. The condensor 22 of the heatpipe is provided at a position lower than the evaporation device and housed in the recess 24 of the wall 7. The evaporation device is fixed in the recess by a fixing member, for instance an another unit 6. As the heatpipe is fixed with both its ends, tight fit is necessary in neither recesses, so that the heatpipe can be removed easily. With this constitution, the RF shielding of the inner housing can be maintained. |
