Solar Water Heating

Pressurized Vacuum Tube Heat Pipe Solar Water Heater

Working Principle:

Vacuum tubes absorb the solar radiation, and convert it into thermal energy, then the thermo energy is transferred to heat pipes via the aluminum fin surrounding heat pipes. The heat transfer medium in heat pipes is vaporized while the heat pipes are heated, and then the medium vapor goes up to heat up the condensers. Then the water in tank is continuously heated by the condensers.
