heat pipe solar collector

Solar Collector Features: 

Evacuated tubes convert solar energy into thermal energy that is transferred to heat pipes by an aluminum fin with high solar energy absorption and low heat radiance loss. The heat pipe adopts such kind of character that could transmit quantity of heat under low temperature. 

Character 

1With a testing pressure of 1.0 MPa, this system has a working pressure of 0.6 MPa. 

2Solar water heaters can still work even with several tubes broken. 

3Highly efficient insulation with integrated polyurethane foam.
