2. Structure of solar water heater
Component description:
HEAT PIPES:
An evacuated-tube collector contains several individual glass tubes,
each containing an aluminum fin and a heat pipe. The heat pipe transfers heat efficiently
to the water in the tank.
WATER TANK:
The storage tank is made of three layers: inner shell, intermediate
foam insulation and outer cladding. The shell is built to hold maximum water pressure
of 150 psi. Shell material is corrosion-proof, food-grade stainless steel. Foam insulation
thickness is designed to self-sustainingly maintain the tank water temperature during
continuous overcast days in the coldest wintertime. Outer cladding is normally
galvanized sheet metal, providing a fine surface finish and a long-lasting life.
EVACUATED TUBES:
Top-quality double-walled tubes are used. There is an
aluminum or copper-coated mirror on the inside surface of the inner glass wall. The
mirror well traps thermal energy inside the tube. On the metal mirror layer, there is
selective absorption coating, which converts over 99% of the energy from visible and
invisible lights.
