The flat-plate solar collector is the basic component of low-temperature heat utilization of solar energy. The flat-plate solar collector is mainly composed of a heat-absorbing plate, a transparent cover plate, an insulating layer and a shell. The heat sink structure is basically in the shape of a flat plate. When the flat-panel solar collector is working, the solar radiation passes through the transparent cover and is projected on the heat-absorbing plate, absorbed by the heat-absorbing plate and converted into heat energy, and then the heat is transferred to the heat-transfer medium in the heat-absorbing plate , to increase the temperature of the heat transfer medium, as the useful energy output of the collector.
