Vacuum thermos is a kind of popular cups. It is aimed at removing the heat transfer medium of convective heat transfer and contact heat transfer and turning it into vacuum to achieve the effect of heat preservation. Therefore, the liquid poured into the vacuum thermos cup can maintain its original temperature for a long time. In life, some people use vacuum mugs to make coffee or keep water cold.
Vacuum insulation bottle is generally a water container made of stainless steel and vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of water and other liquids inside, so as to achieve the purpose of heat preservation.
1. The flask body of the heat preservation bottle adopts a double-layer structure, and the vacuum of the bottle liner and the bottle body can block the transmission of heat.
Moreover, whether the sealing performance of the thermos cup is good also plays a very important role in the thermal insulation effect. The better the sealing, the more difficult it is to transfer heat, so as to make the thermal insulation effect better.

2. Double layer stainless steel vacuum structure vacuum does not transfer heat, which is equivalent to cutting off the heat conduction medium.
The higher the vacuum degree, the better the insulation effect. The vacuum pumping technology is divided into tail pumping and tailless pumping. Now most thermos cup manufacturers use tailless pumping because this technology is more advanced.
3. The inner tank is plated with copper or silver. The inner tank is plated with copper or silver, which can effectively form a layer of heat insulation net in the inner tank of the thermos cup.
In this way, the copper plating can effectively reduce the heat lost through radiation by reflecting heat radiation. The flask or cup is generally a container made of stainless steel and vacuum layer. It has a cover on the top and is sealed tightly. The vacuum insulation layer can delay the heat dissipation of water and other liquids installed inside, so as to achieve the purpose of heat preservation.
That’s all for the relevant knowledge of vacuum thermos cup. I believe many people will know why vacuum thermos cup has such good insulation effect after reading this article on how to use vacuum thermos flask and the principle of vacuum thermos.
