2.Features of heat pipe solar vacuum tube collector
-With triple selective coating, it has a higher heat efficiency than common vacuum tubes
-With patent heat pipe, it can work between -40°c to 300°c
-With patent insulating layer: PU+aluminium silicate wool, less heat loss
-Even 1 or 2 vaccum tubes broke, it can work normally
-Perfect combination with building
-It can be used for large solar heating projects or home use
3. Split heat pipe solar vaccum tube collector working principle
-first, solar radiation is absorbed by vacuum tube,then it is changed into heat and diliveried to heat pipe by aluminum fin.
-working liqiud inside heat pipes absorbs heat and vapors,then it flows toward the top of pipe and releases latent heat of evaporization at condenser.
-antifreezing fluid in flowpassage flows along the pipe and absorbs the latent heat, to the water tank.
-After that,the gas cools down and returns to the bottom to repeat the cycle.
