principle of super heat pipe solar evacuated tube as below:
the super heat pipe solar evacuated tube whosemethod of tranmissive heat is by sunrays shine on the aluminum fin within high evacuated glass tube.then the aluminum find absorbs the heat and transfer it to core copper heat pipe.the heat pipe will transfer heat energy to the top of heat pipe.then the top head of heat pipe will conduct heat exchanges with manifold.it is very easily of installation for the solar collector system.At the same time ,there is no water inside tube.Even if one of super heat pipe solar evacuated tube does not wokr or operate, but there whole symstem is also still working and no effect.
specifications as below table;
