Question! The working principle of solar water heaters in winter can it light

Question! The working principle of solar water heaters, solar water heaters in winter can it light (Solar water heater) refers to solar energy as an energy heating water heater. It is one of the three water heaters and gas water heaters, electric water heaters with parallel. The first layer of glass on the sun shine through the second layer of heat pipe heat absorbing layer of black glass, heat absorbing solar energy, because it is between two layers of glass vacuum insulation, the heat can not be to the rumor, only can pass the glass tube inside the water, the water heating the glass tube, the heated water becomes lighter along the heating surface up into the insulating glass storage tank, a relatively low temperature of the water along the barrel surface into the glass tube backlight tube complement, so the cycle of that heat storage bins of water constantly heating, hot water so as to achieve the purpose. Solar water heaters to solar energy into heat, the water from the low temperature to high temperature, hot water use to meet people in life and production. Solar water heaters according to the structure into the form of vacuum tube solar water heaters peace plate solar water heaters, vacuum tube solar water heater is currently mainly occupied 95% domestic market share. Household vacuum tube collector tube solar water heater is made, storage tanks and other related stand annexes to rely mainly on solar energy is converted into heat energy collector. Collector tube with hot water cold water sinking floating principle, so that the water produced micro-circulation and achieve the required hot water.

Tank liner made of imported food grade SUS304-2B thick stainless steel plates, automatic high frequency welding. Corrosion-resistant, long life, water quality by testing, in line with national drinking water standards. CFC-free polyurethane foam technology imported automatic temperature high pressure quantitative foaming process thicker insulation, better 360-degree three-dimensional thermal insulation effect, life is more durable. Light purple tube solar vacuum tubes are all using borosilicate glass 3.3 special hardware pipe special materials, vacuum high transmittance, low emissivity high absorption, resistance to thermal shock resistance, can withstand hail 26mm, -20 degrees can be used normally, -40 degrees will not be damaged by frost. Solar light stand using structural stability of high-quality steel, metal forming, electrostatic spray, nice, bearing good, durable.
