Abstract

The progress of concentrating photovoltaic technology is regulated the temperature of photovoltaic modules and improving the power generation efficiency of photovoltaic systems have become the core issues to ensure the stable operation of the system. In this work, a heat dissipation technology combined with pulsating heat pipe （PHP） and fin was proposed to reduce the operational temperature of photovoltaic panel. And the experiment tested the operating characteristics and heat dissipation efficiency of the combined device. The results found that the combined heat dissipation structure of the PHP and fin can efficiently and quickly reduce the working temperature of photovoltaic panels. Meanwhile, the high heat dissipation demand of photovoltaic panels could lead to a large temperature difference between the two ends of the PHP, as well as accelerating the working fluid in the pipe. Thus, it could achieve the better startup characteristics and higher heat transfer efficiency of the PHP. Besides, the tested results indicated that the fins could effectively reduce the thermal resistance of the PHP, which could further improve its heat transfer efficiency during the operation. Finally, based on the measured results, a comprehensive evaluation was conducted on the enhanced effect of the combined heat dissipation structure of the PHP and fins. It also discussed the application scopes and advantages of this technology, which provides technical support for further promoting the application of distributed photovoltaic power generation technology.
