1.2L Thermos Liner

The thermos bottle is made of double-glazed glass. Both layers of glass are coated with silver. Like a mirror, it can reflect the heat rays back, which cuts off the passage of heat radiation. The vacuum between the two layers of the thermos bottle destroys the conditions of convective conduction. The thermos cap uses a cork that does not easily transfer heat, blocking the passage of convective heat transfer. The three roads of heat transfer are perfectly blocked, and the heat can be retained for a long time. However, the heat insulation of the thermos is not so ideal, and some of the heat can still run out, so the holding time of the thermos has a certain limit.


The function of the thermos is to maintain the temperature of the hot water in the bottle, to cut off the heat exchange between the bottle and the outside of the bottle, so that the "heat" inside the bottle can not be discharged, and the "cold" outside the bottle cannot enter. If you put ice cube in the thermos, the "hot" outside is not easy to run into the bottle, and the ice cube is not easy to change. Therefore, it is scientific to call a thermos a thermos because it can protect both "hot" and "cold".
