Solar water heaters convert solar energy into thermal energy and heat water from low temperature to high temperature to meet people's needs in life and production. Hot water is used. Solar water heaters are composed of all-glass evacuated collector tubes, water storage tanks, brackets and associated accessories. The conversion of solar energy into thermal energy mainly relies on glass evacuated collector tubes. The temperature of the surface of the collecting tube exposed to sunlight is high and the temperature of the rear surface of the collecting tube is lowe, and the water in the tube produces a temperature difference reaction. The principle of hot water floating up and cold water floating up. Water sinking is used to cause microcirculation of water to achieve the required hot water.

Solar water heaters are composed of vacuum collector tubes, insulated water tanks, brackets, connecting pipes, etc.

◆Heat sensor: The heat collecting element in 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 heating time can only occur when there is sunshine.

At present, all-glass solar collector vacuum tubes are popular in the Chinese market. The structure is divided into outer tube, inner tube, dry absorption coatinglective, getter, stainless steel clip, vacuum sandwich and other parts. Mature foreign collectors are flat plate collectors. Flat plate collectors have the advantages of long service life, high stability and recyclability. However, due to their slightly higher cost than vacuum tube collectors, many low-cost flat plate collectors produced in China perform well. of the collector is indeed not good, so the performance of the flat collector has been distorted by the domestic major solar power manufacturers. However, the development of flat panel sensors in the solar energy industry is unstoppable and cannot be stifled by the misdirection of some manufacturers. Today, many water supply and drainage designers in design institutes have become aware of this problem.

The vacuum tubes of solar collectors inFully glass are usually made of extra hard high borosilicate 3.3 glass and adopt selective vacuum spray coating process. It can be divided into aluminum-nitrogen single-target coating process and copper, aluminum and stainless steel three-target coating process.

◆Insulated water tank: 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.

The insulated water tank of a solar water heater is composed of three parts: an inner tank, an insulating layer and a water tank shell.

Water tank liner is an important part of water storage chot, and the strength and corrosion resistance of its materials are crucial. There are stainless steel, enamel and other materials on the market. The quality of thermal insulation material is directly related to thermal efficiency and its use at night and early morning, which is especially important in the cold Northeast. At present, the best insulation method is global automated foaming process insulation made of imported polyurethane. The shell is usually made of colored steel sheet, galvanized sheet or stainless steel sheet.

Insulated water tank with solar support requires good insulation effect, corrosion resistance, clean water quality and service life of more than 20 years.

◆Support: A frame that supports the collector and insulated water tank. The structure must be firm, resistant to wind, aging and rust. The material is generallya colored steel plate or aluminum alloy. The lifespan should be up to 20 years.

◆Connecting pipes: pipes that carry hot water from the collector to the insulated water tank and carry cold water from the insulated water tank to the collector, making the entire system forms a closed loop. Properly designed and properly connected circulation lines are essential for optimal operation of the solar installation. Hot water pipes must be insulated. The quality of the pipeline must meet standards and guarantee a lifespan of more than 10 years.
