Knowledge of  Vacuum Tube Heat Pipe Solar Energy Water Heaters  

 

Working Principle:

Heat pipe pressurized solar hot water heater is a high efficiency closed loop thermosyphon system.

1. How vacuum tube heat pipe works.

Copper heat pipe has special heat conductive liquid in it, which has very low boiling point(20 °C -25 °C ).

Solar energy is absorbed by vacuum tube and then it is transmitted to copper heat pipe via the aluminum fin. As the special conductive liquid has low boiling point, it gets to boil easily.

The heated liquid becomes vapour with heat from sun goes up to heat pipe header(condenser)which is pluged into tank.After vapour reaches to cold water, it becomes liquid again and fall down to the bottom of copper heat pipe,and then starts a new circulation.

2. How the water in tank becomes hot.

Cold water in water tank absorbs the heat from copper heat pipe and become hot water and goes up to water tank top. At the same time,cold water falls down to bottom of water tank. As the copper heat pipe bring the heat from vacuum tube continuously, water in water tank will keep circulating.

3. How the hot water goes out.

As its name shows, it is a pressurized system, so this system must be a welded close loop system completely. It can connected with the city tap water system directly. Cold water inlet is installed on bottom and hot water outlet is installed higher than cold water inlet. Once you open the hot water outlet switch, cold water will come into the water tank bottom and push the hot water out.

This system is different from the non-pressurized gravity system, as long as the tap water pressure is enough, it can be installed on the ground even you use the hot water on third floor.

(Remark: Non-pressurized gravity system must be installed on a place where it is higher than the hot water use terminals.)

Feature:

1. Using vacuum tube copper heat pipe solar collector,very high heat efficiency.

2. No water in vaccum tube when it works,even one or two vacuum tubes broke, the system can work normally.

3. It has perfect frost resistance performance, works well even in very cold places,such as Russia,Sweden,Mongolia.

4. Bearing high pressure(Max 7 bar),it can be connected with high pressure city tap water system.

5. Installation is freestanding,no limitation on installation location.

6. Easy installation and free maintenance.
