【Abstract】 Based on thermal analysis, calculating methods for determining the overall heat loss coefficient, the efficiency factor and the heat removal factor of heat pipe evacuated tubular collector are presented. Instantaneous efficiency curves for both single evacuated tube and complete evacuated tubular collector are also tested. Experimental results coincide with theoretical calculations quite well.更多还原
