The heat exchanger maintains the normal operation of the machine of the ship, therefore heat exchanger is very important for cooling ship machinery devices. The heat pipe has high heat transfer efficiency and can transfer heat quickly with a small temperature difference. The purpose of this research is to discuss the important influencing parameters in the heat pipe manufacturing process. The performance test of heat pipe with angle of inclination and thermal response test is also conducted. Experimental results heat pipe could heat dissipate heat 160W below thermal resistance R=0.12℃/W. Otherwise, the heat pipe heat may be became a candidate cooler in future for ship machinery devices.
