Abstract

A cooling unit for cooling a semiconductor package has a heat sink and an electric fan device. The heat sink includes a heat receiving portion for heat generated by the semiconductor package, and a heat exchange portion thermally connected to the heat receiving portion. The heat exchange portion is located adjacent to the heat receiving portion and separate from the semiconductor package. The heat sink is movable toward and away from the semiconductor package, and always urged by a plate spring toward the semiconductor package. The electric fan device sends cooling air at least to the heat exchange portion of the heat sink.
