Working principle:
Heat Pipe solar collector consists of a vacuum tube and a copper heat pipe inside. The vacuum is placed in an inclined mode. The selective coating on the inner tube converts the solar energy into
heat and transfer the heat to the heat pipe via the aluminum fin. When heated, the medium 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 lowered, then the vapor becomes liquid and 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. Even though the heat pipe is a vacuum and the boiling point of the medium liquid has been reduced to only 25-30
oC, the freezing point is still the
same as water at sea level, which is 0
oC. As the heat pipe is located within the evacuated tube, brief overnight temperatures as low as -30
oCwill not cause the heat pipe to
freeze.
*Features:
Higher heat efficiency, the temperature at the condenser could be as high as 250oC
Heat pipe made of red copper and heat is conducted via medium liquid;
No water flowing inside the vacuum tube, more resistant to low temperature;
Strong aluminum alloy manifold mould with air-flow design, better wind resistant;
Withstanding high pressure in operation;
Module design, easy combination.
