Working Principle rapidly. The vapor rises to the top of the heat pipe and transfers heat. As the heat is lost at the top, the vapor condenses to form a liquid (water) and returns to the bottom of the heat pipe once again to repeat the process.
The heat pipe is hollow and evacuated, as same as the solar tube. There are a small quantity of purified water and some special additives in it. The heat pipe used in Huayang solar collectors has a low boiling point. Thus, when it is heated, the water vaporizes

The Inner Tank |
Unit-designed Heat-absorption Structure and lower loss. Patented design isolates copper coil from inner tank. This can greatly reduce galvanic corrosion.
Evacuated tube, aluminum fin and heat pipe arc closely integrated, realizing faster heat transfer
