14*70mm Condenser Copper Keymark Approved High Efficiency Heat Pipe
Solar Collector
Solar heat pipe collector working principle:
1. The heat pipe series solar heat pipe 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 aluminum 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.
