The performance analysis of longitudinal finned heat pipe applying to air conditioning

Based on circular finned heat pipe has a big resistance and is easy to be deposited in the air-conditioning heat recovery system, Zhuang Chen et al [1] proposed to apply the separating longitudinal finned heat pipe to the air-conditioning heat recovery system. In this paper, the authors made a three-dimensional numerical simulation of a basic unit of 500 mm long longitudinal finned bundle and circular finned bundle using Fluent software. Through the comparison of heat transfer coefficient, power coefficient and other parameters, the authors conclude that the longitudinal finned heat pipe used in the air-conditioning heat recovery system has certain advantages.
