The technology of glass collector tubes for solar water heaters is mature. The hot water produced by the glass tubes is returned to the water tank for insulation without loss, so it heats up quickly and has a high utilization rate throughout the year.
The flat plate carries hot water through the connection pipe between the water tank and the plate. The heat loss is high and the plate conducts heat through the filling fluid, so there is a maintenance cost problem. In addition, the flat plate indirectly heats the water in the water tank and the temperature rises slowly if the water tank heater is turned off, the temperature rises even more slowly.
< strong>The solar water heater is composed of vacuum collector tube, stainless steel insulated water tank and bracket, 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. “All-glass solar collector vacuum tubes are currently popular in the 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 bee 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. Connecting pipes
The pipes that carry hot water from the collector to the insulated water tank and carry cold water from the insulated water tank to the Collectors are connected to the pipes to that the entire system forms a closed loop.
