  1    performance  

The job of the heat pipes in the evacuated tubes is to rapidly transfer away the heat. The heat pipe capacity must therefore be greater than the evacuated tube's maximum output to avoid a bottle neck in the heat transfer chain. SANENG heat pipes have an average heat transfer capacity of >110Watts. The maximum heat output of an SANENG vacuum tube is around 65Watts.

  2    Freezing  Protection 

Although the heat pipe inside is a vacuum and the boiling point has been reduced to 25°C, the freezing point is still the same 0°C as water at sea level. Since the heat pipe is located within the vacuum insulated glass tube, night temperatures as low as -40°C will not cause the heat pipe to freeze. The water used in heat pipes still freezes in special cold conditions, but it freezes in a controlled way that does not cause swelling of the copper pipe.

  3    Advantages of heat pipe solar collector   

Comparing with vacuum tube solar collector:

1. High efficient heat pipe tubes;

2. High pressure and anti-freezing collector;

3. Less heat loss for closed loop circulation;

4. No risk of tube breaking from thermal shock;

5. No risky of tube breaking from water freezing;

6. No system drainage even though one or several tubes are broken;

Comparing with flat panel solar collector:

1. Higher efficiency collector, much lower heat loss with vacuum insulation;

2. Super anti-freezing performance for heat pipes in cold weather condition;

3. No system drainage even though one or several tubes are broken;

4. More convenient in system parts carrying and installation;
