  • Vacuum heat insulator and method of manufacturing the same
    Patent number: 10883647
    Abstract: A vacuum heat insulator which can prevent lowering of a heat insulation performance in its thickness direction, while ensuring a sufficient strength, is provided. The vacuum heat insulator reduces heat transfer in the thickness direction of a core from one surface side of the core to the other surface side thereof. The core includes a first fiber layer and a second fiber layer. The first fiber layer includes short fibers layered in the thickness direction. The second fiber layer includes long fibers layered in the thickness direction, and thickness fiber bundles which extend in the thickness direction, and which bind the long fibers. The long fibers are longer than the short fibers.
    Type: Grant
