Abstract

An electronic component cooling apparatus capable of minimizing a reduction in cooling efficiency even when discharge of air heated is restricted to two directions and reducing a manufacturing cost. The cooling apparatus includes a heat sink including an elongated base having a plurality of radiation fins arranged thereon, as well as a fan unit. The fan unit includes a casing in which an impeller provided with a plurality of blades and a motor for revolving the impeller are received. The casing is releasably mounted on the heat sink. The heat sink and the casing of the fan unit cooperate with each other to define two discharge ports and form an air flow space which continuously extends between an end of the radiation fins facing the casing and an opposite wall of the casing.
