Heat pipe solar water collector

Heat pipe solar collector structure and priciple: the heat pipe is hollow with the space inside evacuated, much the same as the solar tube. Freeze Protection:Because the heat pipe is located within the evacuated glass tube,biref overnight temperatures as low as -20oC will not cause the heat pipe to freeze. High heatconduction coefficient:is 2000-5000times of metal materials High heatconduction coefficient:is 2000-5000times of metal materials Low temperature difference:less than 4oC difference in 2 meter long pipeTechnology:Model Type SHHPC Manifold casing material Anodized Aluminum Frame material Aluminum Header pipe material Copper Heat pipe material Copper Insulation Polyurethane 55mm or rock wool Rubber seals and rings UV stabilized high temperature silicon rubber Test pressure 9 bar Collector Plane roof/slope roof Angle of operation 10oC-80oC Inlet Outlet Φ22 Specifitions: MODEL Lighting(m2) Heat pipe Supply hot water(L/oC) 20/40containner GW KG diameter lengh No. SHHPC47/12 1.26 Φ47mm 1500mm 12 70/60 28 SHPPC47/18 1.80 18 110/60 42 SHPPC47/20 2.10 20 125/60 46 SHPPC47/30 3.15 30 180/60 69 SHPPC58/12 1.73 Φ47mm 1800mm 12 110/60 40 SHPPC58/18 2.57 18 150/60 60 SHPPC58/20 2.88 20 175/60 64 SHPPC58/30 4.32 30 260/60 98 features: Reliable,efficient,twin-glass solar tubes heat pipe Copper heat pipes for rapid heat transfer --Low maintenance effort --Easy installation of single or multiple units 3.
