CE Approved 15Tubes Vacuum Tube Black Rooftop Heat Pipe Thermal
Solar Collector with Aluminium Alloy Frame
Working Principle:
high pressure heat pipe solar collector is one of the most popular
solar collector with pretty high efficiency.
The selective coating of vacuum tubes converts solar irradiation
into heat energy and transfers to copper heat pipes by aluminum
wrapping.
The heat transfer liquid in heat pipe then vaporize and rapidly
rise to the top condenser.
In active system, a pump circulates water or heat transfer fluid
through the manifold header pipe, taking away the heat to store in
tank water.
The cooled vapor in heat pipe then liquefies and returns to pipe
bottom, waiting for another heat circulation in few seconds.
