VACUUM HEAT-INSULATING MATERIAL, VACUUM HEAT-INSULATING CONTAINER, AND PRESSURE MEASUREMENT METHOD

Title:

VACUUM HEAT-INSULATING MATERIAL, VACUUM HEAT-INSULATING CONTAINER, AND PRESSURE MEASUREMENT METHOD

Document Type and Number:

WIPO Patent Application WO/2022/130920

Kind Code:

A1

Abstract:

This vacuum heat-insulating material comprises a film, a core, a test layer, and a heated layer. The film forms a hermetically sealed space having a pressure lower than normal pressure in the interior. The core is disposed in the hermetically sealed space. The test layer is positioned between the core and the film and exhibits thermal conductivity that corresponds to the pressure in the hermetically sealed space. The heated layer is positioned between the core and the test layer and is induction-heated by an alternating magnetic field.
