Solar energy is an inexhaustible source of energy in today's world, and its use is increasingly widespread. The water of vacuum tube solar water heater can be used for bathing, dishwashing, laundry and so on. They reduce the use of other fuels to heat water, protect the environment, and reduce the workload caused by the nature of the work. Vacuum tube solar water heater is composed of collector, water storage tank and bracket. The collector can directly convert solar energy into heat energy. The collector makes use of the working principle of bathing, cooling and sinking of hot water can make water microcirculation, thus achieving the purpose of heating.

The definition

Vacuum tubular solar water heater is a heating device that converts solar energy into heat energy and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. It can be subdivided into all glass vacuum tube type, heat pipe vacuum tube type and U tube vacuum tube type solar water heater.


Use for

Vacuum tubular solar water heater operates automatically and statically without any dangers. Such as personal supervision, noise, pollution, leakage, fire and poisoning. It is safe and reliable, environmentally friendly, energy-saving and beneficial to the nation and the people. The utility model has the function of sewage purification, and the water source is clean and pollution-free. It has good heat preservation and frost resistance. Large area installation can insulate the floor. In cold winter, solar water heater has strong anti-freezing ability. Large-scale installation of solar energy can also isolate floors when you feel very hot. In sunny weather, you can take a hot bath without using any fuel. If you have a cold, you can wash clothes and dishes in winter, so you won't be drowned in cold water.


Working principle

The collector plate of the vacuum tube solar water heater consists of several vacuum tubes. Just like many slender hot water bottles side by side. The inner and outer layers of the vacuum tube are all vacuum tubes. The outer surface of the inner tube is coated with special materials, which can effectively absorb solar radiation energy, convert it into heat energy. And guide it into the water in the tube. Based on the principle that the ratio of cold water to hot water is small. The natural convection cycle between the heat pipe and the heat preservation water tank forms the rise of cold water and hot water. And the water in the water tank gradually becomes hot. 

By storing hot water in an insulating tank, people can use hot water at any time. Hot or cold water is conveyed through connecting pipes to form closed loops as required. Through the control system display and water temperature, water level automatic control. It can also prevent the vacuum tube from bursting after high temperature air drying and sudden injection of cold water. The main frame supports the collector plate and the water insulating tank. It is also used to adjust the angle between the collector plate and the ground surface to form the optimum inclination angle. So that the solar water heater collector plate can obtain the maximum solar energy.



Vacuum tubular solar water heater has good thermal insulation and freezing resistance. It will be very safe and comfortable to use at home. It will also be very cost-effective, and there will be no cost in the latter part. It is energy-saving and environmentally friendly, using solar energy and renewable energy.
