Experimental Study on the Temperature Evenness of Heat Pipe Using Magnetic Nano-Fluids as the Working Medium in Permafrost Regions

Abstract:

The simulation experiment system of permafrost regions with low temperature environment and the temperature evenness test system of heat pipe were established and researched experimentally. The temperature evenness of heat pipe using magnetic nano-fluids as the working medium and the traditional heat pipe were comparative analysised at the simulation environment of permafrost regions with low temperature. The experiment results show that the heat pipe using magnetic nano-fluids as the working medium has better thermal conductivity, less heat transfer temperature difference, and the more heat transfer ability, more widely applicable temperature range, more applicable to the life and the higher working efficiency. The results provide a new idea to develop higher efficiency heat pipe having the better temperature evenness.
