Heat pipe flat panel solar collector.

2.3 Heat pipe flat panel solar collector.

Heat pipe flat panel solar collector combine the advantages of heat pipe and flat solar plate.
Characteristics

Solar collectors are made from black paint coating or highly selective vacuum sputtering coating.
Heat pipe transmit energy from flat plate to horizontal tube. No vertical water tubes.
Insulation layer minimize thermal emission in low seasonal temperatures.
Solar tempered glass as covering and protect collector from hailstone.
Absorber area is 2.0 ㎡
Material of plate: Copper or Aluminum plate.
Solar absorptance:95 % (±2%)
Thermal emittance: 5% (±2%)
