Refrigerant immersion heat dissipation device

Abstract

This invention provides a refrigerant immersion-type heat dissipation device, which includes an evaporator and a heat exchange component. The evaporator has a chamber containing liquid refrigerant. The heat exchange component is disposed in the chamber and immersed in the liquid refrigerant, and includes a plurality of heat sinks with small holes, a connecting heat conduction plate, and an external equipment heat transfer plate. The connecting heat conduction plate extends out of the evaporator to enable the external equipment heat transfer plate to conduct heat to the external equipment. By directly exchanging heat with the liquid refrigerant through the heat exchange component, the heat transfer path can be shortened, and the heat exchange efficiency and heat dissipation effect can be improved.
