Unreasonable.
Be exposed to wind, sun and rain. From a safety perspective, strong winds are likely to present safety risks, so they need to be secured. There are many ways to repair it, such as pulling metal cables, drilling expansion screws, welding brackets, etc.
The working principle of solar water heater: sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the second glass layer, absorbing the heat from solar energy. It is vacuum insulated, so heat transfer will be significantly reduced (radiation heat transfer still exists, but there is no thermal conduction or thermal convection). , causing the water in the glass tube to heat up. The water becomes lighter and enters the insulated water storage bucket alongthe heating surface of the glass tube. The relatively low temperature water in the bucket enters the glass tube along the backlight surface of the glass tube. glass tube for refilling. This continuous cycle keeps the water in the insulated water storage bucket heated to achieve the hot water goal.
Solar water heaters are composed of vacuum collector tubes, insulated stainless steel water tanks, brackets, connecting pipes, etc.
1. Vacuum collector tube?
The collector is the heat collecting element of the system. Its function is equivalent to the electric heating tube of the electric water heater. Unlike electric water heaters and gas water heaters, solar collectors use radiant heat from the sun, so the heating time can only be when the sun is shining. “Vacuum tubes for solar collectors allglass are currently popular in Chinese market. The structure is divided into outer tube, inner tube, selective absorption coating, getter, stainless steel clip, vacuum sandwich and other parts.
2. Insulated water tank
An insulated water tank is a container for storing hot water. Since solar water heaters can only work during the day and people usually use hot water at night, the hot water produced by the collector during the day must be stored in an insulated water tank. The volume is the total amount of hot water used each night.
3. Bracket
The solar water heater bracket is the supporting member of the solar water tank and an important part of the solar water heater.
4. Connection pipes
The pipes that carry hot water from the collector to the water tanku insulated and carry cold water from the insulated water tank to the The manifolds are connected to the pipes so that the entire system forms a closed loop.
