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;
