Abstract
A heat dissipation apparatus is suitable for dissipating heat from heat-generating elements in a medium-voltage drive. The heat dissipation apparatus comprises: a heat-dissipating substrate, wherein the heat-generating elements are placed on at least one of a first surface and a second surface of the heat-dissipating substrate; at least one heat pipe group each of which includes a plurality of heat pipes, each heat pipe having an evaporation section and a condensation section, wherein the evaporation section is buried in an inner layer of the heat-dissipating substrate for absorbing heat from the heat-generating elements; and a plurality of fins arranged to be intersected with each heat pipe and connected to the condensation sections of the heat pipes, so as to transfer the heat released from the condensation sections to air. The contact portions between the heat pipe group and the fins are arranged in triangle staggered arrangements.
