Abstract
The present invention provides a heat sink device, suitable to the heat dissipation of a high-power medium-voltage drive power cell. The device comprises a heat dissipation substrate having a first surface, a second surface and an inner layer between the first surface and the second surface; a heat pipe having an evaporation section and a condensation section. The evaporation section is buried in the inner layer of the heat dissipation substrate, and the condensation section is used to dissipate the heat from the evaporation section to the air. The power elements of the high-power medium-voltage drive power cell are disposed on the first surface and the second surface, respectively.
