Experimental Study on Heat Transfer Enhancement of Wire Mesh Wick Gravity Heat Pipe
Through the experiment of inserting copper wire mesh wick into the heat pipe,the thermal re-sistance factors such as the starting time,stable temperature and thermal resistance of the gravity heat pipe which mainly affect the heat transfer performance of the heat pipe with different mesh number copper wire mesh structure are analyzed and studied.The experimental results show that under the same working con-ditions,the start-up time of the heat pipe with different mesh size is shorter than that of the ordinary heat pipe,and the heat pipe with small mesh size has lower stable temperature.The thermal resistance first de-creases and then increases with the increase of mesh size.In the scope of this experiment,3# tube has the best heat transfer performance.This experiment provides a direction for the study of heat transfer enhance-ment of gravity heat pipe.
