Focus on high-quality water bottle for 15 years

Why can’t you put the thermos water bottle in the refrigerator

Presumably, most consumers know that the thermos water bottle has the effect of heat preservation and cold preservation, and the effect of heat preservation and cold preservation can reach more than 6 hours. However, some consumers may misunderstand the cold insulation function of the thermos water bottle, and think that putting the thermos water bottle in the refrigerator can prolong the cold insulation effect. In fact, this practice is very harmful to the performance of the thermos water bottle.

As for why can't the thermos water bottle be put into the refrigerator, we should start with the way of heat transfer. There are three ways of heat transfer: heat radiation, heat conduction and heat convection. The thermos water bottle mainly solves the heat loss caused by the first two heat transfer modes, and the vacuum interlayer can effectively inhibit the occurrence of heat transfer. At the same time, some manufacturers will plating silver on the inner layer of the thermos water bottle, which is also a means to prevent heat transfer.

In this way, it is not difficult to see that the main reason why the thermos water bottle can keep warm is to inhibit the heat transfer. However, if the thermos water bottle is put into the refrigerator for freezing, it will be affected by the cold shrinkage, and the thermos water bottle will not be able to withstand the cold pressure, which will lead to the bending deformation of the internal structure of the thermos water bottle, making the thermos water bottle lose its insulation performance.
