Heat Pipe Solar Water Heater

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.
