ANALYSIS OF STEADY-STATE OPERATION OF HIGH TEMPERATURE HEAT PIPE AND OPTIMIZATION OF THE WORKING MEDIUM

ABSTRACT
High temperature heat pipes exhibit excellent heat transfer performance and can operate stably under high temperature conditions above 750 K. They are widely used in heat recovery and heat removal processes. In this paper, a flow and heat transfer model is established to calculate the temperature, pressure, and velocity distribution of the high temperature heat pipe, and the results are similar to the experimental data. In addition, the working medium of the high temperature heat pipe is optimized through a novel optimization method based on probability, and it is concluded that sodium has better heat transfer performance than lithium and potassium under 800-1000K operating conditions. The optimal result is consistent with the simulation result, which provides a reference for the optimization of working medium in high temperature heat pipes under other operating conditions.
