With the working principle of phase-change heat transfer,micro heat pipe has a broad application space in the respect of highly efficient solar thermal control. According to growing thermal control demand for solar plane heat collectors,design of grooved flat aluminum heat pipe was discussed. Various factors influencing heat transfer performance such as working fluid,material of heat pipe shell,wick structure and filling rate were studied. An experimental platform was set up to investigate the characteristics of fabrica-ted heat pipes heat transfer performance both experimentally and analytically. The conclusions are that non-condensable gases has great impact on performance of heat pipes,so measures should be taken to avoid leaking;in order to ensure heat pipe quality,the processes of cleaning,filling of working fluid and sealing need to be careful;reasonable filling rate helps boost heat pipe ability of temperature u-niformity.
