PROBLEM TO BE SOLVED: To provide a cooler for a power converter that is capable of efficiently cooling a joined power converter regardless of a shape of a screw for joining the power converter. SOLUTION: The cooler for a power converter is composed of a body 3 which includes a fin 5 constituting a flow path 9 for flowing a cooling medium, and a lid 4 for closing the flow path 9 and it has the screws 13 respectively having a length longer than a sum of a height (h) of the fin 5 and a thickness (l) of a fin base as a base for the fin 5 and used for joining the power converter 11 to convert DC power to AC power with the body 3. Each part where a screw hole 12 for inserting the screw 13 is formed is provided to the body 3 so as to be longer than the length of the screw 13. The cooler cools the power converter 11 by joining the power converter 11 to the body 3 with the screws 13 via a heat sink 26. COPYRIGHT: (C)2007,JPO&INPIT
