Heat Pipe Solar Water Heating System
The
selective coating on the inner cover of the Vacuum Tubes
converts solar energy and transfers heat to the heat pipes
by aluminum fins. The liquid in the heat pipe changes into vapor
which rises to the condenser. Then the heat passes through the heat
exchanger, the water inside of water tank is being heated, and the vapor
becomes liquid, returning to the bottom of the heat pipe. This
transference of heat creates a continuous circulation as long as the heat
pipe vacuum tube collector is heated by sun.
Heat
is transferred by liquid to the water tank and heat the water efficiently. In
addition, heat pipe vacuum tubes is highly freezing resistance, which ensures
higher efficiency in cold areas.
Pressurized
water tank ensures high comfort when customer uses hot water, the water flow
and water pressure is much higher than compact non-pressurized solar water
heater.
