Composite heat-dissipating module

Abstract

A composite heat-dissipating module includes a heat-dissipating plate, an impeller, and a pump. The heat-dissipating plate includes at least one heat-dissipating section and a circulating pipe. The heat-dissipating section is thermally connected to an object to be dissipated. The circulating pipe contains a liquid coolant that circulates in the circulating pipe. The impeller is mounted adjacent to the heat-dissipating section for driving air to cool the heat-dissipating section. The pump drives the liquid coolant to circulate in the circulating pipe between the pump and the heat-dissipating section for cooling the heat-dissipating section.
