The solar water heater can convert solar light energy into heat energy, is environment-friendly and energy-saving, and has become popular. The vacuum tube solar water heater has high heat preservation performance, and occupies a large area in domestic market in China. However, the vacuum tube has the defect of tube explosion and glass fragility. The flat-plate solar water heater is safer because of being made of toughened glass, and is more and more popular with users because of higher heat collection efficiency. However, in the northern area, the heat preservation effect of the flat-plate solar water heater is poor, so that the flat-plate solar water heater cannot directly run away in order to prevent the flat-plate solar water heater from freezing out, and most manufacturers adopt a mode of running away antifreeze in a runner and performing secondary heat exchange with water in a water tank to solve the problem of freezing prevention. Due to the adoption of the heat exchange structure and the fact that the antifreeze needs to be replaced periodically, the flat-plate solar water heater is complex, and the investment and maintenance cost is high. The popularization and the use of the flat-plate solar water heater in the north are limited.
