This article is a heat pipe cooling device, which is configured to cool a semiconductor device or the like to be used for a vehicle control apparatus and the like. This article comprises a heat block configured to contact the semiconductor device or the like, a plurality of heat pipes, and a plurality of heat dissipation fins connected by the heat pipes. This article is configured such that heat is transferred from the semiconductor device or the like to the heat block, then transferred from the heat block to the heat dissipation fins through the heat pipes, and finally dissipated from the heat dissipation fins.
