同轴径向热管传热特性实验研究
Experimental study on heat transfer characteristics of coaxial and radial heat pipe
摘要
Abstract
In order to find out the distribution of temperature on the outer wall and the heat transfer coefficient of heat pipe with different filling rates, the experimental investigation was conducted to study the heat transfer characteristics of five different filling rates of carbon steel-water heat pipe which was radial and coaxial.The temperature on the outer wall during different heat fluxes was collected.According to the principle of the least square method, an experimental correlation was established to reveal the relationship among heat transfer coefficient, working fluid rate and heat flux.The results show that, on the basis of experimental condition, the heat transfer performance of 50％ filling rate of the heat pipe is the best.The errors of the heat transfer coefficient of different heat pipes are within 7.92％.关键词
