Product detail:

  Evacuated Tube Solar Thermal Collector

------------------------------------------------------

 

Working Principle of Thermosyphon:

 

Evacuated tube solar thermal collectors consists of a vacuum tube, a heat pipe, a metal heat absorption wing and the connecting manifold. The metal heat absorption wing with selective absorption coating converts solar energy into heat energy and transfers it medium liquid inside. The vacuum between the two glass tubes works as insulation. The liquid in the heat pipe changes into vapor which rises to the condenser. When passing through the heat exchanger, the heat is absorbed and the temperature is lowed, and the vapor becomes liquid, returns to the base of the heat pipe. This transference of heat is a continuous circulation as long as the collector is heated by the sun.
