The characteristic of heat pipe:
Heat pipe is the most effective het transfer component nowadays. Especially, it can transmit heat if great distance through a small section without any outside power.
The structure of heat pipe vacuum tube:
1.copper heat pipe
2.silicone gasket
3.a luminum fin
4.vacuum tube
Working principle
1.Inside the heat pipe is a vacuum closed cavity of 1.3*(10-1~10-4)Pa, and filled with working liquid
2.When one side is heated, the liquid evaporate in the core, the steam flow to the other side under slim pressure and emit heat condensing to liquid, and the liquid flow to evaporate side be capillarity along the porous material.
By such endless cycle, the heat is transfermed from on side to the other side.
1. Solar water heater system of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becomes lighter and goes to the water tank, while cold water the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated .
