Abstract
Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.
Claims17
A vacuum-insulated article having a shape, comprising:
- a first metallic wall and a second metallic wall;
- a first insulating space having a pressure of less than 760 Torr formed between the first metallic wall and the second metallic wall;
- a vent communicating with the first insulating space to provide an exit pathway for gas molecules from the first insulating space, the vent being sealable for maintaining a first vacuum within the first insulating space following evacuation of gas molecules through the vent;
- a seal sealing the first insulating space at the vent;
- and
- multiple layers of a metallic reflective material in foil form disposed within the first insulating space, the metallic reflective material having an emissivity of less than 0.4 for wavelengths in the range of from 2 to 50 micrometers,
- the vacuum-insulated article being configured such that the article maintains its shape at up to about 2500 deg. F.
