For export trade superconducting heat pipe solar collectors collector U-tube solar collector

U-tube solar collector has the following advantages: ▲ vacuum within the water does not go, it does not scale, long-term use does not affect the collection efficiency; ▲ installation angle is not limited, and can be placed horizontally stacked vertically, that balcony wall; ▲ can be used for dual pressure unpressurized; ▲ tube breakage occasionally does not affect the operation of the machine; ▲ system uses steel connection, no silicone seals bring aging, leaking phenomenon; ▲ using a circulating pump to force liquid heat transfer cycle, efficiency high; ▲ to the series and parallel to a major collector. Solar collectors parameters: a vacuum of not less than 5 × 10-3 Pa coating copper nitrogen aluminum reflectance absorption rate ≥0.93 ≤0.03 start-up temperature ≤25 ℃ nausea drying temperature is 250 ℃ freezing tolerance of minus 50 ℃ life ≥ 15 years of anti- wind 30m / s (11 grade) anti-hail 35mm high boron glass, silica glass absorber plate of copper, aluminum
