heat pipe solar vacuum collector,tube.

The characteristic of Heat Pipe Solar Collectors 1) Reliable, efficient, twin-glass evacuated tubes. 2) Red copper(TU1) , The water is heated by the heat pipe rapidly. 3) There is no water in the ,so the tube will not break in the winter. 4) It can be combined with the architecture perfectly, standard frame suitable for pitched roof or flat roof . 5) It can be combined with existing pipeline. 6) Significant advantages over flat plate. 7) Can be used all year round in the cold climate. 8) Improves the environment and save your fuel cost. The Principle of Thermosyphon Metal consists of a , 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. Product Applications 1) Domestic, industrial and commercial heating use 2) Suitable for open or closed Loop (glycol-water) 3) Space heating 4) Caravan Parks, Hotels, Schools, Public Showers/Kitchens , Restaurants 5) For large scale water heatingThe characteristic of U type Solar collectors 1) The vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the U pipe,it can get high temperature.. 2) There is no water in the ,so the tube will not break in the winter. 3) It can be combined with the architecture perfectly, standard frame suitable for pitched roof or flat roof . 4) It can be combined with existing pipeline. 5) Significant advantages over flat plate. 6) Can be used all year round in the cold climate. 7) Improves the environment and save your fuel cost. U type Solar collector working principle Evacuated tubes convert solar energy into heat energy, that is transferred to U pipe by an aluminum fin with high solar energy absorption and low heat radiance loss,Liquid (antifreezing liquid or water) in the U pipe heats up, and the U pipe conducts thermal energy to the water inside the storage tank directly (or through internal copper coil),With a testing pressure of 1.2 MPa, Working pressure is 0.6MPa
