Abstract
A cooling device mounts a fan unit above a heat sink. The heat sink is mounted on a heat-generating element or buried therein. The cooling device produces an effective air flow and achieves a uniform cooling action by having the heat sink formed in various shapes. The cooling fan is disposed away from the heat sink or to the side of the same and is used for effective cooling through an air conduit passage formed by pipes or a cover.
