Abstract
A thermal insulation device includes a first plate, a second plate formed to nest adjacent the first plate with a gap between the first and second plates, a porous material disposed between the plates, and a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient. Multiple such sets of plates may be used to form an enclosure for a device that thermally insulates the device from ambient.
Claims20
A thermal insulation device comprising;
- a first plate;
- a second plate formed to nest adjacent the first plate with a gap between the first and second plates;
- a porous material disposed between the plates;
- and
- a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient.
A thermal insulation enclosure comprising;
- a first plate;
- a second plate formed to nest adjacent the first plate with a gap between the first and second plates;
- a porous material disposed between the plates;
- a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient;
- a duplicate set of first and second plates having a porous material and sealing layer formed to mate with the first and second plates to form a chamber;
- and
- a device disposed within the chamber that is thermally insulated from ambient by the enclosure.
A method comprising:
- pressing a porous material between two plates such that the plates are separated from each other by a gap defined by the porous material;
- and
- in a partial vacuum, depositing a conformal sealing layer to cover the porous material in the gap between the two plates to form a gas seal of the porous material from ambient and maintain the partial vacuum.
