U-tube solar collector Product Introduction:
U-tube solar collector is a solar thermal collection device, mainly composed of U-tube, vacuum tube, fin header, etc. The working fluid in the U-tube absorbs the solar heat in the vacuum tube and then transfers the heat to realize the conversion of solar energy into thermal energy for heating, hot water and other purposes.

Note:
(1) Rated efficiency:The total irradiance on the daylighting surface of the collector is 1000W/m²,and the temperature difference between the average temperature of the collector and the ambient air temperature is 50℃.Calculate the efficiency value of the solar collector according to the instantaneous efficiency equation of the collector's daylighting area.
(2) Rated power:The total irradiance of the collector lighting plane is 1000w/m²,and the collector power when the temperature difference between the average collector temperature and the ambient air temperature is 50°C is equal to the product of the rated efficiency and theday lighting area and 1000W/m² .
