evacuated tube solar collector
Features:
1. Solar heat pipe collector consists of heat pipe,vacuum, stand, manifold.
2. It is very high efficiency that heat pipe transmit heat very quickly.
3. No water in vacuum tube, anti-freezen.
4. Solar heat pipe collector is best fitting for solar pressure water heating system.
5. Well wind, snow and hail resistance.
Working Principle:
The heat pipe is hollow with the space inside evacuated, much the same as the solar tube. In this case insulation is not the goal, but rather to alter the state of the liquid inside. Inside the heat pipe is a small quantity of purified water and some special additives. At sea level water boils at 100oC (212oF), but if you climb to the top of a mountain the boiling temperature will be less that 100oC (212oF). This is due to the difference in air pressure.Based on this principle of water boiling at a lower temperature with decreased air pressure, by evacuating the heat pipe, we can achieve the same result. The heat pipes used in AP solar collectors have a boiling point of only 30oC (86oF). So when the heat pipe is heated above 30oC (86oF) the water vaporizes. This va pour rapidly rises to the top of the heat pipe transferring heat. As the heat is lost at the condenser (top), the va pour condenses to form a liquid (water) and returns to the bottom of the heat pipe to once again repeat the process.
