How Does Doyoung’s Stainless Steel Water Bottle Maintain Its Insulation Effect in 4 parts?

Many people don’t understand that a stainless steel water bottle is just a simple two-layer iron sheet. How can it achieve insulation? In fact, the secret lies in the technology of “vacuum insulation”.

Vacuum insulation is a method of using vacuum to block heat transfer. As is well known, there are three main ways of heat transfer in physics and chemistry: conduction, convection, and radiation. Conduction refers to the direct contact and transfer of heat through an object. For example, when we place our hands on a hot water bottle, we can feel the heat. Convection refers to the transfer of heat through the flow of fluids, such as water vapor produced when boiling, which can take away some of the energy from boiling water. However, radiation refers to the transfer of heat in the form of electromagnetic waves, such as sunlight shining on us, which is a manifestation of thermal radiation.

1.The Origin of Stainless Steel Bottle

The modern thermos water bottle was invented by British physicist Sir James Dewar in 1892. He was conducting research on gas liquefaction at that time. To liquefy gas at low temperatures, the first step was to design a container that could isolate the gas from the external temperature. Therefore, he asked a glass master to make a double-layer glass container for him, with the inner walls of the two layers coated with mercury. Then remove the air between the two layers to create a vacuum.

2.The Principle of Water Bottle

Doyoung’s stainless steel water bottle adopts a double-layer stainless steel structure, with a vacuum drawn in the middle. This design cleverly blocks the transfer of heat: firstly, there are almost no air molecules in the vacuum layer, such as hydrogen molecules with reducing properties and oxygen molecules with oxidizing properties. Therefore, heat cannot be transferred through the above-mentioned conduction or convection methods. Secondly, stainless steel material has a strong reflection effect on thermal radiation, which can effectively reduce the loss and absorption of heat. In other words, stainless steel material can effectively isolate the liquid inside the bottle from the external environment for energy exchange. At the same time, due to the vacuuming action in the middle layer, the pressure inside the layer will decrease. However, due to the hardness of the stainless steel material, it can also ensure that the product will not deform.

In addition, some stainless steel water bottle will place a layer of charcoal particles at the bottom of the cup before sealing, and the charcoal particles will be fully burned at a high temperature of 500 degrees, which can exhaust the air in the hollow part and achieve almost complete vacuum effect. Charcoal particles play an important role in the insulation process of Doyoung’s stainless steel water bottle. Before vacuuming, charcoal particles are placed at the bottom of the cup and subjected to high-temperature combustion to further increase the vacuum degree. At the same time, carbon particles have strong adsorption capacity and can adsorb trace gases and moisture remaining in the vacuum interlayer.

3.Why is the higher the vacuum degree, the better the insulation effect?

This is because in a vacuum state, there is almost no medium that can transfer heat, and heat conduction is greatly weakened; Meanwhile, in a vacuum environment, without air convection, heat convection cannot occur, and there is even less opportunity for heat transfer and exchange.
