Why does the stainless steel vacuum insulation product fail to keep warm if it falls flat?

Stainless steel vacuum insulation products rely on the vacuum layer between the inner and outer tubes of the product to achieve the insulation effect. If it is broken or collapsed, the inner and outer pipes of the product will encounter "heat conduction" and will not be insulated. In order to prevent "flatness" from falling, high-quality products should be made of steel with appropriate thickness.
