摘要(Abstract)：

以大面积太阳模拟器考察了平板式太阳能集热器、热管真空管式太阳能集热器、全玻璃真空管式太阳能集热器室内稳态下的性能。经测定,全玻璃真空管式太阳能集热器的时间常数为1235 s,其压力曲线随流速变化平缓。在辐照强度为900 W/m2、进口温度低于57℃时,平板太阳能集热器的效率高于热管真空管式和全玻璃真空管式太阳能集热器;进口温度高于57℃时,式真空管式太阳能集热器的效率高于平板式太阳能集热器;进口温度高于64℃时,全玻璃真空管式太阳能集热器的效率高于平板式太阳能集热器。在工作温度范围内,全玻璃真空管式太阳能集热器的效率低于热管真空管式太阳能集热器。设计、流动和换热特征影响了集热器的性能。
