Research on Numerical Simulation of High Temperature Heat Pipe

The paper researches the strong heat transfer numerical simulation to the transitional period of medium and low temperature of high temperature heat pipe heat exchanger. It sets the calculation model of the headquarters according to the characteristics of heat transfer of heat pipe heat exchanger, and forecasts the fluid temperature field distribution outside of pipe reasonably and accurately by FULENT software. The results show that heat exchange performance in hot will keep steady well in the early and decline significantly in the late by changing heat pipe amount or increasing flow, and the change in cold is small, but it will keep steady well in the early and decline significantly in the late both in hot and cold by increasing import and export temperature. It lays the foundation for the theoretical research and promoting application to high temperature heat pipe heat exchanger.
