[0002] Solar water heater has been widely used by people due to its energy saving and environmental protection. Solar water heater heats water through heat collecting plate, and the specific process is as follows: solar radiation transmits through glass cover plate, is absorbed by heat collecting plate, and is transmitted to water in heat absorbing tube along rib and tube wall. The water in heat absorbing tube is heated and the temperature rises, the specific gravity decreases and rises, forming an upward power, forming a thermal siphon system. With the continuous upward movement of hot water and storage in the upper part of the storage tank, the water with lower temperature is continuously supplemented through the lower circulating pipe, so as to circulate repeatedly, and finally the whole tank of water is raised to a certain temperature.
