Patent ID: 8630090

Claim:
A heat dissipation device for a power conversion module, comprising: a casing comprising a heat-dissipation fin unit having a plurality of heat dissipation fins arranged at positions spaced apart from each other by predetermined intervals, the casing having a mounting space therein; a high-heat-dissipation heat sink installed in the mounting space of the casing; and a circuit board coupled to a lower surface of the casing, wherein: a power conversion device is mounted to the circuit board, the heat-dissipation fin unit and the mounting space are arranged at the same surface of the casing, the mounting space of the casing is formed at a position corresponding to a high heat generating part of the circuit board where more heat is generated than at other parts, and the high-heat-dissipation heat sink is configured to dissipate heat generated from the high heat generating part of the circuit board.
