An experimental study was conducted to evaluate the thermal performance of a vacuum tube solar air collector that is based on micro heat pipe arrays (MHPA) and features wavelike fins attached to the condenser section of the MHPA. The experimental results were used to analyze the thermal performance of the collector, particularly the temperature distribution in the different localizations of the air...
In order to improve the utilization of solar energy, we use the new flat-plate heat pipe in the solar photovoltaic/thermal (PV/T) system to meanwhile gain electricity and heat. In this way, the temperature of solar cell could be effectively reduced to improve power generation efficiency, and the heat dissipation of solar panel could also be stored up through the forced circulation of the aqueous solution...
A novel micro heat pipe array was used in solar panel cooling. Both of air-cooling and water-cooling conditions under nature convection condition were investigated in this paper. Compared with the ordinary solar panel, the maximum difference of the photoelectric conversion efficiency is 2.6%, the temperature reduces maximally by 4.7??C, the output power increases maximally by 8.4% for the solar panel...
