Flat plate solar collector
Flat solar collector is a device that absorbs solar energy and transfers heat to working fluid. It is a special heat exchanger. The flat plate solar collector is composed of one heat-absorbing plate cord and one shell and one piece of transparent cover plate and thermal insulation material and some related components. After the circulation pipe and the heat preservation water tank are connected, it absorbs solar energy to heat the cold water.
When the flat plate solar collector works, the solar passes through the transparent cover and is projected on the heat absorption plate, absorbed by the heat absorption plate and converted into heat energy, and then transferred to the heat transfer medium inside the heat absorption plate and the temperature of the heat transfer working medium rises as a useful energy output of the heat collector. At the same time, the heat-absorbing plate after the temperature rise must inevitably dissipate heat to the surroundings through conduction, convection and radiation to cause heat loss of collector.
