【Abstract】 A method for determining the thermal performance of vacuum collector tubes with heat pipes is studied in this paper. By means of a specially designed "measuring block", heat output of the collector tube can be determined by measurement of the large temperature difference between two ends of a built-in thermal resistance, so as to increase the accuracy of measurenent can be ensured. Making a comparison between testing data and that published by previous literatures, it is proved that the method described in present paper is satisfactory.更多还原
