Flat-plate solar collector is a device that absorbs solar radiation energy and transfers heat to the working medium. It is a special heat exchanger. The working medium in the collector exchanges heat with the distant sun.
Sunlight shines through the transparent cover plate to the heat sink coated with the absorption layer, and most of the solar radiation energy is absorbed by the absorber, converted into heat energy, and transmitted to the working medium in the fluid channel.
In this way, the cold working fluid from the bottom inlet of the collector is heated by the solar energy in the fluid channel, and the temperature gradually rises. Standby in the water tank is the useful energy income.
At the same time, due to the increase of the temperature of the heat sink, the heat is dissipated to the environment through the transparent cover plate and the outer shell, which constitutes various heat losses of the flat-panel solar collector.
1. Simple structure, flexible and delicate, easy to maintain;
2. The form is changeable, and it is easy to be perfectly integrated with the building;
3. Long service life and stable performance;
4. Anti-freezing and anti-scaling, defrosting and snow melting;
5. The water quality is clean and beneficial to health.
