CE solar energy collector

solar energy collector Material of solar energy collector 1. Inner water tank: SUS 304-2B food grade stainless steel 2. Outer water tank: color steel plate, galvanized sheet / 304 BA stainless steel 3. Bracket: galvanized sheet with plastic spurts models /aluminum alloy 4. Insulation layer: polyurethane foamed 55-65mm 5. Vacuum tube: 3.3 high borosilicate glass 6. Fasteners: stainless steel screw 7. Sealing ring: polymer silicone rubber 8. Reflective angle: 45°golden angle Thevacuum tubeofsolar energy collector our solar water heater has the high absorption rate and low emission rate, Absorption rate: 0.90-0.93 (AM1.5) Emission rate: 0.05-0.075 ( 80±5) Vacuum tightness: P≤5.0*0.001Pa Idle sunning property parameters : Y=220-260./KW Average heat loss coefficient: Ult=0.6-0.7W(.) It means the temperature in the water tank is range from50 to 95 Heat Preservation: 72 hours Hail Resistance: 25mm Working pressure: 0.05Mpa The principle of thermosyphon of solar energy collector 1. Because of the larger proportion of hot water than cold water, cold water flows downward and hot water goes upward. The water will be heated continuously between water tank and vacuum tube. In other words, hot water always floats on cold water. 2. The hot-water flows to the water tank from the vacuum tubes. Because of the proportion, cold water flows to vacuum tubes from the water tank. 3. The cold water is heated in vacuum tubes. After it becomes hot water, it flows to water tank again. The water circulates constantly between water tank and vacuum tubes; the cold water in water tank will be hotter and hotter. 4. Finally, all cold water will be heated to be hot water. This is the heating course of cold water. Specification ofsolar energy collector water tank solar energy collector reflective angle:0-90
