Working Principle Of Vacuum Flasks

Working Principle Of Vacuum Flasks

The body of the insulated cup is vacuumed. No heat is transferred in a vacuum, so heat transfer is isolated. Generally speaking, the insulation cup double layer of the interlayer will be plated copper or silver, in order to form a heat lock network, reduce heat loss caused by heat radiation.

The insulation cup body adopts double-layer airtight structure, which can avoid the convection between the heat inside the cup and the outside air, thus reducing the convection of heat.

Our stainless steel coffee flaskhave been exported to more than 50 countries internationally.
