The 5-layer vacuum tube is a significant technological advancement in the field of water heating systems. This innovative design consists of a glass tube with five different layers, each playing a crucial role in the functioning of the vacuum tube and its ability to efficiently heat water. The water heater structure, influenced by this 5-layer vacuum tube, has a profound impact on the overall performance and effectiveness of the water heating system. In this article, we will delve into the details of the 5-layer vacuum tube and explore the effects of its unique structure on water heater efficiency and functionality.
Currently, some solar water heater manufacturers use 5-layer vacuum tubes, so what is a 5-layer vacuum tube and what is the effect in the structure of the water heater? Let’s find out with Thptlaihoa.edu.vn.
What is 5-layer vacuum tube?
The 5-layer vacuum tube is a vacuum heat-absorbing tube with an outer layer made of high-grade transparent glass (with high strength and good heat resistance). Inside the glass layer is a vacuum and the following 5 special layers:
- Layer 1: The outermost layer is high-grade transparent glass, which helps in sunlight exposure and easy heat transfer.
- Layer 2: Made of copper alloy with high heat transfer ability.
- Grade 3: Anti-infrared radiation and clean water because it is made of Titanium Dioxide
- Layer 4: Layer 4 helps the vacuum tube absorb up to 99.5 % of sunlight thanks to its aluminum alloy construction.
- Layer 5: As an anti-scale layer – helps to prevent the inside of the pipe from getting dirty, the water passing through will not be sticky.
What is the effect of the 5-layer vacuum tube in the structure of the water heater?
The 5-layer vacuum tube is an important part of a solar water heater and on the market today, it is also one of the most modern and multi-layered heat-absorbing tubes, helping to increase the absorption capacity of the solar water heater. more heat to the water. Depending on the capacity, the water heater has the right number of vacuum tubes to heat water more efficiently. For example, Tan A Dai Thanh solar water heater has a capacity of:
- 130 liters: there are 12 glass tubes
- 180 liters: there are 18 glass tubes
- 215 liters: there are 21 glass tubes
The job of these vacuum tubes is to absorb and transfer heat . When attached to the water tank through the holes in the tank body, the vacuum tube will absorb heat and transfer heat to the water, then the water will be heated up easily according to the following operating principle:
- When you turn on the water source to supply water to the tub, the water will overflow into the entire interior of the vacuum glass tube and be heated right here.
- When there is sunlight, the sunlight will pass through the glass tube and then contact the heat-absorbing layer, then the heat will be absorbed, making the inside of the tube heated up, that temperature will affect the temperature. The heat transfer layer causes the water contained in the tube to be heated as well.
- According to the principle of natural thermal convection, liquids will tend to move upwards when encountering high temperatures, and they will move downwards when encountering low temperatures. Therefore, the hot water in the glass tube will be moved to the top of the tank, then the cooled water in the tank will move down through the glass tube, the water here is heated and moved again. upward, continuously following the rotation so that the water in the tank will be heated and used.
- When there is no sunlight, the water will increase in temperature from the container to the water in the vacuum tube. The process of making hot water will temporarily end when the water temperature in the container and the vacuum tube are equal.
Just now is the information about the 5-layer heat-collecting vacuum tube, hope you will understand more about the 5-layer heat-collecting vacuum tube as well as its effects to choose for yourself a better product, if you have any questions.

In conclusion, a 5-layer vacuum tube is a type of solar collector used in water heaters. The tube consists of five layers including the inner glass tube, the outer glass tube, the vacuum layer, the absorber plate, and the insulation layer. Each layer plays a crucial role in enhancing the efficiency and effectiveness of the water heater.
The inner and outer glass tubes work together to create a vacuum layer, which acts as excellent insulation, preventing heat losses from the system. This insulation layer not only keeps the water hot for longer periods but also reduces the energy consumption required for heating.
The absorber plate, usually made of copper or stainless steel, absorbs the solar energy and converts it into heat. This allows for the quick and efficient transfer of thermal energy to the water passing through the tube. Additionally, this design provides higher surface areas for absorption, maximizing the utilization of sunlight, and increasing the overall efficiency of the water heater.
Furthermore, the insulation layer ensures minimal heat loss to the surroundings, enabling the water heater to maintain high temperatures even in colder climates. This makes the 5-layer vacuum tube water heaters suitable for various weather conditions and enhances their performance and longevity.
In conclusion, the 5-layer vacuum tube water heater structure greatly affects its efficiency and effectiveness. The design elements, including the glass tubes, vacuum layer, absorber plate, and insulation layer, work in synergy to maximize solar absorption, minimize heat loss, and provide hot water consistently. With advancements in technology and continuous research, the 5-layer vacuum tube water heaters are becoming increasingly popular and are expected to play a vital role in the transition towards more sustainable and energy-efficient heating systems.
