摘要
Abstract
Alkali metal heat pipes have important applications in space nuclear power systems and are important components of the spacecraft radiant radiator.In this paper,the sensitivity of the potassium heat pipe to the liquid filling ratio,the count of layers and mesh of the wick and the thermal load power are investigated,and the heat transfer performance of the heat pipe with multi-parameter coupling is optimized.The analysis results show that the temperature difference of the heat pipe decreases with the increase of the liquid filling ratio and the mesh count,and in-creases with the increase of the count of wick layers and thermal load power.Moreover the overall temperature increases and the vapor velocity decreases with the increase of thermal load power.For potassium heat pipe,the count of wick layers and the thermal load power are sensitive to the heat transfer performance.The optimal combination of parameters obtained is 1.0 of liquid filling ratio,7 layers of 350 mesh wick and 712.475 W of thermal load power.The analysis and optimi-zation method adopted in this paper have engineering reference value for the design and optimiza-tion of heat pipe radiators.关键词
