With the continuous development and development of renewable energy, solar energy has attracted people's attention for its environmental protection and renewable characteristics. As a major industry in the application of solar energy achievements, solar water heaters have been popularized in thousands of households in cities and rural areas. In addition, solar water heaters are more and more popular because of their energy saving, good heat preservation and low investment costs in the later stage.

Now there are mainly two types of solar water heaters: vacuum tube solar water heaters and flat plate solar water heaters; the common vacuum tube solar water heaters mainly rely on absorbing solar radiation heat energy to heat cold water to provide convenience for people's life and production.

However, due to weather reasons, especially for solar energy users located in alpine regions, in the long winter when the temperature is low, it is very easy to cause solar water heaters to freeze, and they have to let the solar water heaters go into an idle state and switch to other energy-intensive heat sources. Lose the meaning of energy saving and environmental protection of solar water heaters; in addition, in winter, the phenomenon that the heat-absorbing vacuum glass tubes are frozen and cracked due to the cold often occurs, and the phenomenon that solar water heaters cannot be used also often occurs. It is very likely to pose a threat to people's life safety.
