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. “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 water.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. 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.
What parts does the structure of a solar water heater consist of? What materials are they mainly made of?
Solar water heating is an industry ma major player in the application of solar energy. It provides people with new environmentally friendly, safe, energy-saving and hygienic water heater products that absorb radiant heat. energy from the sun and heat cold water to provide people with energy-saving equipment used in daily life and production.
System composition
◆Heat collector: 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 take place during the day, when the sun is shining.
◆Insulated water tank: Like the insulated water tank of an electric water heater, this is a container for storing hot water. Since solar water heaters cannotwind operate only during the day and people usually use hot water at night, the hot water produced by the collector during the day should be stored in an insulated water tank. The volume is the total amount of hot water used each night. Tongle enamel lined pressure insulated water tank has good thermal insulation effect, corrosion resistance, clean water quality and service life of more than 20 years.
◆Connecting pipes: channels 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. That properly designed and correctly connected circulation pipes achieve optimal operating conditions for the solar system is crucial. Hot water pipes must be insulated. The pipes must bee high quality and guarantee a lifespan of more than 20 years.
Each square meter of flat solar collector can generate heat equivalent to 2.5 kilowatt hours of electricity per normal day of sunshine. It can save about 200 kilograms of standard coal every year and further reduce CO2 emissions. more than 700 kilograms. The widespread use of solar water heaters, especially for domestic hot water, heating and air conditioning, will significantly improve the pollution situation on earth while saving money.
What parts does a solar water heater consist of? How does it work?
Solar water heaters consist of evacuated collector tubes and insulated stainless steel water tanks. , supports and connections Made up of pipes, etc.
1. Vacuum collector tube?
The collector is the heat collecting element of the system. Its functiontion is equivalent to the electric heating tube of the electric water heater.

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 corresponds to the total quantity of waterhot used every 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.
Structural principles of solar water heaters
Solar water heaters consist of the following elements:
1. Heat Collector: Collects heat in the system. Component. Its function is equivalent to the electric heating tube in an electric water heater. Different from electric water heaters and gas water heaters, solar collectors use radiant heat from the sun, so the heating time can only be during the day lwhen the sun is present. shines.
2. Insulated water tank: Like the insulated water tank of an electric water heater, it is a container for storing hot water because solar water heaters do not can operate only during the day, and people in general. use hot water at night, heat should be collected via an insulated water tank. The hot water produced by the device during the day is stored. The volume is the total amount of hot water used each night. It adopts Tongle enamel inner tank. bear pressure and insulate the water tank, which has good insulation effect, corrosion resistance and good water quality. Clean, with a service life of more than 20 years.
3. Connecting pipes: channels that carry hot water from the collector to the insulated water tank and carry cold water from the insulated water tank to the collector, make the whole system form a loop closed. OfProperly designed and properly connected circulation pipes are essential for the solar system to achieve optimal operating conditions. Hot water pipes must be insulated. The pipes must be of high quality and guaranteed to last 20 years. years. The lifespan above.
Each square meter of flat solar collector can generate heat equivalent to 2.5 kilowatt hours of electricity on average per normal sunny day. It can save about 200 kilograms of standard coal every day. per year, which can reduce over 700 kilograms of CO2 emissions. Widespread use of solar water heaters, including domestic hot water, heating and air conditioning, will significantly improve the Earth's pollution situation while saving money.
< p>Solar water heaters Structure and principle: The solar water heater is a device that uses the sun's energy to heatr water from low temperature to high temperature. 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 back surface of the collecting tube is low, 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.
The solar water heater is a photothermal converter, different from traditional natural uses, such as drying and lighting. “The vacuum tube is the heart of the solar water heater. Its structure is like a bottlethe thermos elongated, with a vacuum between the inner and outer layers. The surface of the inner glass tube is covered with a spectrally selective absorption coating using a special process to maximally absorb solar radiation energy. After being irradiated by sunlight, the photons strike the coating and the solar energy is converted into thermal energy. Water absorbs heat from the outside of the coating, water temperature increases, density decreases, hot water rises and cold. water with a higher specific density decreases. The hot water is always in the upper part, i.e. in the water tank. Heating hot water in a solar water heater has little to do with the outside temperature and depends mainly on light. When a kitchen or bathroom faucet is turned on, hot water from the water heater flows according to the natural fall. The steeper the fallnde, the higher the water pressure.
