The scientific principle behind vacuum technology: the key to efficient cold preservation and warmth

Detailed analysis of the internal structure of the portable thermos cup and its working mechanism. The core technology of this type of product is the use of advanced double-layer or multi-layer structure design concept, and the interlayer space is filled with inert gas or completely evacuated. This design can significantly reduce the heat transfer efficiency, making it difficult for the external temperature to affect the liquid state in the inner tank, thereby achieving the function of maintaining the initial temperature stably for a long time.

From a physical point of view, there are three main forms of heat conduction: conduction, convection and radiation. In this type of insulation equipment, since the air between the two walls has been eliminated, the energy exchange phenomenon caused by the vibration of air molecules is reduced. This, coupled with the application of special coatings, further weakens the intensity of infrared emissions and together constitutes a nearly closed energy barrier system. Laboratory data show that after several hours or even more than one day under the same conditions, the water temperature in this type of thermos cup can still be maintained within a satisfactory range.
