The collector is the most important part of the solar heating system, which is responsible for converting solar radiation energy into heat energy of the medium. The most common type on the market is the all-glass vacuum tube collector, which has the characteristics of high heat collection efficiency and simple structure, but the vacuum tube itself is not antifreeze and is not suitable for use in low temperature environments. Although flat-plate heat collectors and heat pipe-type vacuum tube heat collectors have overcome the problem of anti-freezing and cracking, their cost is relatively high, and the cost of large-scale engineering use is too high. Ceramic plate heat collector, it not only has high heat collection efficiency, but also the cost is much lower than traditional heat collectors. There is water circulation in the flow channel of the ceramic plate. When the ambient temperature is lower than 0°C, the water needs to be drained to prevent the ceramic plate from freezing and cracking, so it is not suitable for year-round use. the
