Full glass double vacuum solar heat collecting pipe of the ten strengths 1. No scaling: condensing tube and tube whole sealing, tube in the water to solve the ordinary vacuum tube long term deposit water scaling and cleaning problems problem. 2 anti freeze: suitable for used in cold area of North China, winter is not easy Donglie. Progress vacuum tube service life, expand applicable scope. . running water: if there are an odd condensation end damage, can also be used as ordinary vacuum tube water to water, and the medium into the water is non-toxic, tasteless, to human body without any harm. Even if the lower end is broken, the upper part is still sealed, and the same is not leaking. 4. Fast heat: heat conducting medium is directly arranged in the inner absorb heat from the sun to make up for the metal heat pipe indirect heat transfer and thermal resistance of the ills. High efficiency: in the structure of the water heater with the same specifications ordinary vacuum tube mounting dimensions. Aperture size completely consistent, good interchangeability, application convenient. 6: fried tube can be any time in Sheung Shui, not fried tube, to give consumers a convenient. The basic structure of anhydrous solar heat collecting device: 1: all of the three super high vacuum tube technology. 2. The water tank: selection of 0.5mm entrance high-quality SUS304 2B food grade stainless steel, high frequency welding, weld seam in tank top, the welding seam is not for a long time due to contact with acidic water erosion and leakage. 3 water tank shell: selection of Japanese import SUS304 all stainless steel or color coated steel plate, galvanized sheet. 4. Thermal insulation material: the entrance of polyurethane high pressure, high density, the overall mechanical foaming, constant temperature and aging treatment, fine pore average bubble, reasonable density of obturator rate is high, insulation effect is excellent. 5 sealing ring: the use of today's international general high molecular polymer Si rubber material, life expectancy than ordinary silica gel two times longer. < 6. Water tank end cover: a molding, embossed anti-counterfeiting, inside the lock catch by thickened 1.0 mm aluminum alloy materials (than ordinary thin alloy strength increased two times) or 0.5mm than using a plastic end cover a longer life. 7. Support design: excellence series use thicker galvanized steel plate stamping molding, a comprehensive anti-corrosion treatment, anti UV spray, random flat slope installation, strengthen the hail resistant ability than the using plain cold-rolled plate life twice as long. To choose suitable for winter light best angle 45o; imperial series use a bold alloy profiles and is treated via oxidation, a random flat slope installation, enhance the wind strength, service life is longer than ordinary square tube frame, choose suitable for lighting the best angle 45o heat gain stronger, beautiful appearance. 8. Automatic line: can be equipped with microcomputer automatic control system of water level and water temperature display, automatic water feeding off the water, automatic heating, leakage protection, automatic control.
