split solar collector with heat pipe

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:
1: With a testing pressure of 1.0 MPa, this system has a working pressure of 0.6 MPa.
2: Solar water heaters can still work even with several tubes broken.
3: Highly efficient insulation with integrated polyurethane foam.
