Solar water heater has the difference between copper and copper
The utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production. According to the structure of the solar water heater is divided into vacuum tube solar water heater and flat type solar water heater, mainly vacuum tube solar water heater, occupy 95% of the domestic market share.
Solar vacuum tube with aluminum, copper, stainless steel plating, between the three heat absorption ratio is 3%-4%, but we can not simply say what kind of what kind of good or bad, the manufacturing process of the vacuum tube also includes other aspects, such as coating layers, can affect the absorption of solar energy.On the current mainstream brands in the market for the majority of vacuum tube copper plating, the four layer of a small number of coatings, with only one of the few layers of anti oxidation layer of several major brands. Can absorb the length of wave (cloudy or endothermic), long life (spend the same amount of money, the longer the more cost-effective), strong antioxidant capacity (the wall is not easy to scale) the decision is the vacuum tube of good and bad factors.So it is not very important for the vacuum tube not to be plated.
The solar water heater has the difference between the copper tube and the copper tube is that the water heater of the copper tube is faster than the solar water heater without the copper tube, and the heat preservation of the copper tube is more.
