Vacuum flask heat preservation principle is introduced
Low temperature bottle, the bottle heat energy radiation to the bottle, vacuum flask and effectively control the heat conduction, convection and radiation heat transfer of three kinds of ways.
Made up by inside and outside two bottles. Bottle of connection between the two as a body, two bottles of wall into a vacuum gap to weaken the heat convection, bright silver plating film glass wall surface reflection infrared thermal radiation. Bottle in high temperature, content of the heat energy radiated outward
Vacuum flask adopts double layer stainless steel bile structure, middle vacuum to eliminate heat transfer and convection, bladder package copper foil or aluminum foil to make it produce specular reflection, to leave the radiation reflected. Make temperature heat preservation.
