European style vacuum tube solar collector, heat pipe solar thermal collector

European style vacuum tube solar collector, heat pipe solar thermal collector     

 Solar collector working principle:

1. The heat pipe series solar collector are always connected with existing heating supply device.

2. The selective coating on the inner Cover of the evacuated tubes converts solar energy into heat energy and transfers heat to    the heat pipes by aluminium fins.

3. The liquid in the heat pipe changes into vapour which rises to the condenser.

4. The heat then passes through the heat exchanger and the vapour becomes liquid, returning to the base of the heat pipe.

5. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe.

6. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.

Solar collector features: 

1.Can be matched with any low pressure, high pressure hot water system.

2. Use heat pipe for the heat conduction and can get a high heat absorption effciency and rapid heat transfer.

3. Easy plug-in design and installation.

4.Corrision-resist Aluminum manifold and frame.

5. Can supply hot water to large amount water need.

6.Economical for hotel,school,dormitory,hospital and tall high-buildings.
