HEAT TRANSFER METHOD AND HEAT TRANSFER SYSTEM BASED ON HEAT-PRESSURE CONVERSION EFFECT

WIPO Patent Application WO/2018/137503

A1

A heat transfer method and heat transfer system based on a heat-pressure conversion effect. The method comprises: selecting a heat conducting working medium that meets a requirement of 1.0 kPa/°C according to a determined working temperature interval; then, filling a certain quantity of heat conducting working medium into a closed circulation loop with sufficient rigidity, so that the liquid volume of the heat conducting working medium accounts for 60% to 99% of the total volume of the entire closed circulation loop under the working temperature, ensuring that the interior of the closed circulation loop is basically in a full liquid state; and a liquid heat conducting working medium of a heating end (12) producing thermal expansion due to heating, and forming a pressure wave, wherein the pressure wave produces a compression action on the liquid working medium, and drives the liquid working medium to recirculate, so as to continuously maintain the heat-pressure conversion effect. Stronger and faster heat transfer over ordinary heat pipes can be realized, and an equivalent thermal conductivity coefficient can be up to 50 to 150 kW/ m. K, and the structure design is free and less affected by the gravity overload.
