Abstract
A vacuum heat insulating panel comprises outer wrapping material and core material. A getter is provided in the core material. The outer wrapping material is made by compounding wrapped material without aluminum foil on one side or both sides. The core material is made of an aggregate of glass fiber with uniform laminated structure, and the diameter of the glass fiber is 1-3 μm. A method for manufacturing the vacuum heat insulating panel is also disclosed. Due to very high vacuum degree in the vacuum heat insulating panel, the heat transferring speed is reduced. And, because of the outer wrapping material without aluminum foil layer, the edge thermal bridge effect is eliminated and the heat insulation effect is very good.
