Flat Plate Solar Collector

Working Principle
The flat plate solar collector is a key component of the flat plate solar water heater. It consists of an absorber, glass cover, insulation layer, and shell. The metal absorbing plate with coating is welded onto the red copper pipe. The cold water or other medium liquid is heated when running through the pipe. The transparent cover glass allows visible light to pass through but blocks the far infrared. Thus sunlight can enter through the cover glass and reach the absorber to produce heat, but the far infrared produced by the heat absorber is kept inside. In this way, heat loss is reduced, while the heat-absorption efficiency and the temperature of the absorber can be increased.
There are usually three kinds of coatings: black selective coating, black chrome coating and blue tinox titanium coating. In areas with winter temperature above 0 ℃, a system of direct-heating of cold water is applicable, but in areas with winter temperature below 0 ℃, the user could add a medium liquid in the system to heat cold water indirectly as an alternative.
