ABSTRACT:
A cooling device for a heat generating element which includes a heat sink disposed on a top surface of the element mounted on a printed circuit board, a cooling air throttling mechanism supported by a base surface of the heat sink, and a plurality of heat-radiating fins on the base surface around the throttling mechanism. A plate-shaped cover covers a top surface of the heat sink and has an opening formed at a position facing the throttling mechanism. A cooling fan unit is positioned beneath the opening and mounted to be accommodated in the throttling mechanism.
