Working Principle
Sunlight passes through the glazing and strikes the absorber plate which then heats up, changing solar energy into heat energy. The heat is then transferred to the fluid or gas passing through attached pipes through a convective heat transfer process. The absorber plate’s glass cover is often painted with a ‘selective coating”, allowing light to pass through while still blocking infrared light, allowing the absorber plates to better absorb and retain heat.

Structure Diagram

Absorber plate:
Absorber plates are commonly painted with an absorbent coating, allowing them to absorb and retain heat.

Phenolic foam insulation:
It is designed for preventing heat collector heat loss. The phenolic foam insulation is made of nonabsorbent materials with a small thermal coefficient to ensure the excellent thermal insulation effect.

Glass covers:
These covers allow light to pass through while blocking infrared light, thus effectively reducing energy loss.

Shell (frame, baseplate):
It is used to integrate different components, including the absorber plate, glass covers, insulation materials, and more. It is manufactured using steel, color steel plates, aluminum plates, embossed aluminum plates, and stainless-steel plates. The shell features an excellent rigidity and strength, as well as an easy installation.
