Abstract
Inorganic heat pipe vacuum tube so-lar collector is a new collector .In this paper ,the collector solar water heating system was studied . Basing on the analysis of heat transfer ,the heat transfer mechanism of the all glass vacuum tube solar collector with inorganic heat pipes as heat transfer tubes is studied in the paper ,and the ex-pression of total heat loss coefficient ,efficiency fac-tor ,heat transfer factor ,instantaneous efficiency were concluded .The amount of solar radiation in a typical day was calculated by a program ,and differ-ent factors impacted water temperature in the pipe is analyzed .The results showed that the amount of solar radiation and water mass flow rate have grea-ter impact on water temperature ,the inlet water temperature has little effect on the rising slope of the water temperature of which in collector pipes , while it has greater impact on the water tempera-ture .The results will help guide the design and predict the operation performance of such heaters .关键词
