Abstract
A mounting structure for a power module, in which a power module and a heat sink can be easily separated without additional labor and time and without requiring an extra disassembly space in a product and in which parts are not damaged during the disassembly. In the heat sink (), screw holes () having female screw threads into which power module fixing screws () are screwed are formed so as to penetrate a power module mounting surface () of the heat sink () and heat radiation fins (). The power module fixing screw () is constructed such that, to mount the power module () on the heat sink (), the screw head of the power module fixing screw () is tightened from the printed circuit board () side with a tool () and that, to remove the power module () from the heat sink (), the power module fixing screw () is loosened with the tool () from the heat radiation fin () side on the opposite side of the screw head.
