摘　　要：在传热分析的基础上，提出了确定热管式真空管集热器的总热损系数、效率因子和热转移因子的计算方法。通过实验，还分别测定了单根真空管和真空管集热器的瞬时效率曲线。实验结果与理论计算值符合较好。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.
