PROBLEM TO BE SOLVED: To enable a heat sink device, integrated with a fan motor to be installed in a thin-type equipment by eliminating space in an air suction side which prevents thinning of the equipment. SOLUTION: A space which is large enough to suck air to the upper surface of a heat sink device can be obtained by making the height of a fan 6 and a fin part of a heat sink smaller than a drive means part of a motor, etc., whose structural thickness is limited. The shape of a heat sink base 2 and a fin is formed into a structure of exhaust only in one direction, and a cover 5 is provided to a suction side to prevent exhaust from creeping to suction to compensate for the lowered cooling ability caused by size reduction of the fan 6 and the fin part of a heat sink. According to this constitution, it is possible to set up a structural body in the upper part of a heat sink device near the height of the motor 3, and a heat sink device can be installed in a thin type equipment. |
