The solar water heater is now basically available in the household, and we're not very familiar with solar water heaters, but we probably don't know much about the internal parts, like solar water heaters, which most people don't know very well, and we're going to tell you the difference between solar water vacuum tubes and ordinary pipes。
Solar water heater collectors
The membrane structure varies, resulting in the absorption of solar light. Gradually modified membranes, which are multi-layered membranes, typically have nine layers of absorbent layer by layer, and their absorption properties are gradually higher. As a result of this gradual structure, the launch is increasing more than it is with the temperature, so that the launch is significantly higher at the working temperature of 300-500°c. Also, the aluminum ion in the absorbent layer is much more dynamic and drifting at high temperatures. The internal structure of the membrane is thus in disarray, leading to an ageing of the membrane. In this chronic state of heat, the membrane is released, thus affecting the centralization efficiency and longevity of the vacuum tube。
Absorption of vacuum tubes increased by 12 per cent, launch by 30-40 per cent, overabsorption, low heat damage and high temperature. High-efficiency tubes, overabsorption, high thermal efficiency and high temperature, with more hot water hotter than normal under the same light conditions; high cold tubes, with little heat damage due to the fact that copper ion is 0. 2 lower than aluminium ion and can still work normally in high-cold environments -30°c; high-temperature special effects tubes, with stainless steel ion resistant to high temperatures, air-resistant sun and membrane in 400°c. Under the same light conditions, thermal intake of the general tube is not as high as that of the tri-pipe or even meets the requirements for bathing; when the temperature is lower, thermal damage is greater and the efficiency of the heating is reduced, affecting normal use; especially when the sun is above 270°c, the membranes start to age, fall, absorb quickly and have a significantly shorter lifetime。
Physical chart of solar water heaters
High-temperature special effects tubes, high cold tubes and high-efficiency tubes use three targets, two targets and single-target magnetic spattering; common tubes generally use single-target magnetic spattering。
A. Pipes, where the membrane is sealed at a temperature above 800°c, the removal of parts is inevitable. The high-temperature special effects tube is about 1 cm long and the other tubes are about 2. 5 cm long due to high temperatures. B. Internal tube colours: high temperature, high cold tube interior colours are dark red (due to copper at the bottom of the membrane) and high-efficiency tubes and ordinary tubes are white (due to aluminium at the bottom of the membrane)。
The difference between a solar water heater vacuum tube and an ordinary tube is what we have described above. The largest use of solar water heaters is now a vacuum tube, which, although also used by households, clearly does not reflect the advantage of a vacuum pipe, so at this point in time, if we want to choose a good one, the vacuum tube is the best。
