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;
