Abstract
In an electronic apparatus having a housing and a cooling device for cooling at least one section of heat-generating sections in the housing, the cooling device of the present invention has air-discharge-openings provided on the housing and a cooling fan motor that is thermally coupled with at least one part of the heat-generating section. The cooling fan motor of the present invention has a motor section including a rotary shaft, blades mounted on the shaft and a case, wherein the motor section is disposed at one end of the case and an opening is provided at the other end of the case. The case is made of heat conductive material, and is placed so that the openings face the air discharge openings. This structure effectively and sufficiently dissipates the build-up heat produced by the heat-generating components in the housing, and cools them down. As a result, the cooling device and the cooling fan motor of the present invention contributes to slimming electronic apparatuses such as mobile personal computers, digital video cameras and the like that require cooling devices, without degrading the cooling effect or decreasing a components-mounting-area.
