Solar Water Heater

Heat pipe vacuum tube consists of two parts, all glass evacuated tube and copper heat pipe.

Heat is transferred via heat pipe. When super conductive fluid inside copper pipe is heated, it evaporates and transfers energy to its vapour then condenses, and fluid to its original position due to gravity.

Feature:

Higher Absorbance, Lower emittance, dry exposure up to 270C

Higher efficiency, more heating

Absorbance coating layout:

1 Cmetal reflecting layer (copper)

2 Cabsorbance layer (SS aluminumnitride metal ceramic)

3 Cremittance reducer layer (aluminumnitride)

MAG's vacuum tube adopt dry absorb type selective coating with lower

Remittance, normal tube have not good curve of remittance, when the temperature become higher, the remittance become higher, this will reduce the efficiency of the tube.

3 Higher Point of this new tube

1-Higher efficiency: The absorbance increased by 14% with remittance reduce by 30-40%

2-Higher Heat conduction: Dry exposure temperature up to 270 Cand can endure -30 C environment temperature and still working

3-Higher Vacuum Degree: Unique technology to keep the vacuum degree, stable absorbance which guarantee the long life of the tube

Quality control:

Material quality: Material treatment and production process are extremely important to the creation of a good quality of heat pipe.

It the copper contains too much oxygen or other elements, they will leach out into the vacuum forming a pocket of air in the top of the heat pipe.

This has the effect of moving the heat pipes hottest point (of the heat condenser end) down ward away from the condenser.

We use the Oxygen-free copper with high quality as material of the heat pipe. Chemical composition is:

Thickness of copper pipes wall is 0.7 mm and copper condenser heads thickness is 0.8 mm.

Heat pipe is widely used for the purposes as bellow:

1 To get high pressure from thermal solar system

2 For anti-freezing purpose

3 To accelerate heat transfor.
