Heat pipe vacuum tubes for heat pipe solar water heater

Product Description

1.Working Principle


1.On heat pipe collector,the condenser zone of the heat pipe is inserted to the copper sleeves which are distributed on the water pipe averagely.

2.After the solar energy is absorbed by the vacuum tubes,it is transferres to the heat pipe through the aluminum fin.

3.Heated by the energy,the medium in the heat pipe is working and transferring the heat energy to the condenser zone.

4.When water or other medium in the water pipe flows across the copper sleeves,they would bring the energy and be heated.

5.The heated waer or other medium makes water in the tank hotter by walking across the coils in the tank.
