ABSTRACT:
A cooling device mounting a fan unit (3) above a heat sink (2) mounted on a heat-generating element (1) or buried therein, which produces an effective air flow and achieves a uniform cooling action by having the heat sink (2) embodied in various shapes. Further, a cooling fan disposed away from the heat sink (2) or to the side of the same is used for effective cooling through an air conduit passage formed by pipes or a cover.
