PORTABLE INFORMATION DEVICE

PROBLEM TO BE SOLVED: To provide a portable information device capable of reducing the thickness and weight of a housing even with a radiator equipped in the inside of the device.SOLUTION: A portable information equipment 10 includes a housing 12 having at least one surface formed of an outer metal cover 12a, the housing 12 containing an electronic part 18 and a radiator 20 for discharging heat generated from the electronic part 18. In the portable information equipment 10, the radiator 20 is formed in such a manner that the outer cover 12a is bonded to a metal cover member 22 in an inner surface 12b whereby a fluid containing part 20a is formed between the cover member 22 and the outer cover 12a and then a cooling fluid is sealed into the fluid containing part 20a. 【課題】内部に放熱器を搭載した構成であっても筐体の薄型化及び軽量化を図ることができる携帯用情報機器を提供する。【解決手段】携帯用情報機器１０は、少なくとも一面が金属製の外装カバー１２ａで形成され、内部に電子部品１８が配設される筐体１２を備え、該筐体１２の内部に電子部品１８から発せられる熱を放熱するための放熱器２０を設けている。この携帯用情報機器１０では、外装カバー１２ａの内面１２ｂに対して金属製の蓋部材２２を接合して該外装カバー１２ａと該蓋部材２２との間に流体収容部２０ａを形成し、該流体収容部２０ａに冷却流体を封入することで放熱器２０を構成している。【選択図】図２
