Title:
PHASE CHANGE HEAT RADIATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155900
Kind Code:
A1
Abstract:
Disclosed is a phase change heat radiating device, comprising a phase change assembly internally provided with a phase change heat exchange medium, wherein when the phase change heat exchange medium provided in the phase change assembly is configured in such a way, when the phase change heat radiating device is operating, the atmospheric pressure in the phase change assembly is more than 0.15 MPa. The phase change heat radiating device of the present invention operates at a temperature in a range of 30-80°C with an internal pressure that is much greater than the standard atmospheric pressure and is in a positive pressure non-vacuum environment, a heat-flow density of a heating source is large, the absolute pressure of an evaporation part of the phase change assembly is high, the relative pressure difference between different parts of the phase change assembly under the same temperature difference condition is large, and more of the phase change medium can be driven by the pressure difference so as to improve the heat exchange ability thereof. The mobility of the internal phase change heat exchange medium is improved, the heat-flow density of heat transfer is increased, and efficient heat radiating is more easily realized.
