RevoMax Double Wall Insulated Vacuum Stainless Steel Water Bottle
Can keep "cold"
Putting cold things in it (such as: ice cream) can keep it from melting
The middle of the vacuum cup is a double-layer structure, and the middle is in a vacuum state. There are two ways to lose heat in the air.
1. Heat conduction of the container
2. There is also the heat conduction of air
Therefore, the insulation of the thermos cup needs to be designed according to the above points:
1. Vacuum state can avoid heat conduction of air
2. The inner layer of the thermos cup is silver, which can reflect back the heat conduction energy inside the cup.
If cold things are stored in the cup, it can prevent the external heat from being transferred into the cup.
So the vacuum insulation cup can completely keep "cold."
