PULSATING HEAT PIPE TAKING LIQUID METAL MICRO-NANO LIQUID DROPS AS WORKING MEDIUM

摘要

The present invention provides a pulsating heat pipe taking liquid metal micro-nano liquid drops as a working medium, comprising a pulsating heat pipe body. The working medium of the pulsating heat pipe body is a mixed working medium mainly composed of liquid metal and a surfactant solution, the liquid metal is wrapped by the surfactant, an evaporation section of the pulsating heat pipe body generates a large number of tiny bubbles under a heating condition, the liquid metal is dispersed into multiple liquid metal liquid drops having a micro-nano scale by the generated bubbles, the liquid metal liquid drops are dispersed in the surfactant solution, the liquid metal liquid drops are spontaneously generated in the operation phase of the pulsating heat pipe body, and the liquid metal liquid drops are millimeter-scale liquid drops, micron-scale liquid drops, and nanometer-scale liquid drops. According to the pulsating heat pipe of the present invention, the characteristics such as local microconvection can be generated by combining the ultrahigh heat conductivity of the liquid metal and the liquid metal micro-nano liquid drops, and the heat transfer performance and heat load bearing capability of the pulsating heat pipe can be significantly improved.
