What is a 7-layer Nanomax Vacuum Tube? What is the effect of the water heater?

7-layer Nanomax technology vacuum tube is being produced on some water heaters solar energy today. What type of pipe is this? How does it work in the structure of a water heater? Let’s follow the following article of Tnhelearning.edu.vn.

What is 7-layer Nanomax technology vacuum tube?

– 7-layer Nanomax technology vacuum tube used in solar water heater, is a vacuum heat-absorbing tube, made from transparent glass on the outside (ensures high strength and heat resistance). The vacuum in the middle has the effect of keeping the temperature of the water from being transferred out, and the inside is 7 layers:

• The outer layer of the glass tube (which allows light to pass through and reflect).
• 2 outer absorption layers are sprayed with Nanomax metal dust technology to absorb heat from the sun.
• Magnetron adhesion layer converts radiation into heat energy.
• Next is the Aluminum layer + the absorber used to transfer heat to the inner glass tube layer.
• The inner layer of heat-resistant glass tube is a place to store water and keep heat.
• Finally , a copper + titanium layer catalyzes to heat the water directly and prevent scale.

– 7-layer Nanomax technology vacuum glass tube is capable of:

+ 99% fast water heating to save time.

+ Withstands hail with a particle size of 25mm.

What is the effect of the water heater structure?

The location of the vacuum glass tube in the water heater

The vacuum glass tube is attached directly to the water tank through holes in the tank body. It is an important part of a solar water heater with the task of absorbing heat and then transferring it to heat the water. The number of vacuum glass tubes of the solar water heater depends on the capacity of the container, which has a reasonable quantity. One of the leading manufacturers is Kangaroo solar water heater with a number of models such as:

– 140 liter capacity: 14 glass tubes

– Capacity 160 liters: 16 glass tubes

– Capacity 180 liters: 18 glass tubes

Principle of heating

– Solar water heater works on the principle of natural thermal convection and the phenomenon of the glass cage effect to help convert light energy into heat energy.

– When supplying water to the tank, because the glass pipes are placed at an angle to the horizontal, the water flows inside.

– When there is sunlight on, the light will pass through the glass tube and then be retained by the heat-absorbing layer, causing the inside of the tube to heat up, affecting the heat transfer layer to make the water hot.

– According to the principle of thermal convection, liquids when they encounter high temperatures will tend to move upwards, and when they encounter low temperatures, they will move downwards. Therefore, the hot water in the glass tube will be moved to the top of the tank, and then the cold water inside the tank will move down through the glass tube. The process of making hot water will temporarily end when the water temperature in the container and the vacuum tube are equal.
