Experimental study of heat transfer in a heat pipe

摘要

Heat pipes are a promising cooling system due to the fact of high efficiency and nonavailability of moving parts such as pumps. The experimental investigation of heat transfer in a flat heat pipe has been carried out. The temperature field on the heat pipe has been evaluated using an infrared camera and K-type thermocouples. The IR-camera data and K-type thermocouple data have been compared. The linear dependence of the power supplied to the evaporator on the temperature difference between the evaporator and the condenser is shown.
