Abstract：In order to improve the heat dissipation of the power element,the power element is immersed in the liquid working medium of the heat pipe heat exchanger to different degrees,and the gravity heat pipe test is carried out to study the limit heat dissipation capacity of the heat pipe radiator under different immersion degree and contact type,the heat transfer performance of the heat pipe under fixed liquid temperature of the working medium,the wall temperature of the power element and the contact surface of the heat pipe heat exchanger,and the temperature uniformity of the outlet section of the cold air side.The test results show that the heat generated by the power element can be transferred to the outside world directly by using the phase transformation heat of the working medium,which can eliminate the high thermal resistance of the contact surface and ensure the consistency of the surface temperature of the power element to the maximum extent.Compared with the contact heat transfer,the heat transfer capacity by immersed phase change under vacuum is significantly improved.The liquid temperature and the wall temperature of the power element can be used as a target parameter to monitor the temperature of the submerged power element.
