Problems solved by technology

However, the heat-insulating part is not necessarily limited to the planar shape. For example, when a vacuum heat insulating material is placed on the outer box side of a refrigerator box formed by an inner box and an outer box, there are protrusions or steps in the heat-insulating part. It is difficult to directly apply plate-shaped vacuum insulation materials

Abstract

The invention provides vacuum heat insulation material, a heat insulation box and equipment employing the vacuum heat insulation material, and a method of making the vacuum heat insulation material, wherein the vacuum heat insulation material has improved production property, can be made by common devices, is low in cost and good in heat insulation property. The vacuum heat insulation material comprises wrapping material (2) with gas isolating property and core material (4) wrapped by the wrapping material (2); a surface of the vacuum heat insulation material is provided with grooves (9), and a backside opposite to the surface provided with the grooves (9) is provided with protrusion rib portions (10) corresponding to the grooves (9); the grooves (9) and the protrusion rib portions (10) are formed by equal volume deformation, so the thickness (t1, t2, t3) in an insulation direction is equalized, and the width (L1, L2) of a deformation scope is proximately equal.

Description

technical field [0001] The present invention relates to a vacuum heat insulation material and a heat insulation box using the vacuum heat insulation material, in particular to a vacuum heat insulation material suitable for cold energy equipment, a heat insulation box, equipment and a manufacturing method. Background technique [0002] Conventionally, urethane foam has been used as a heat insulating material used in heat insulating boxes such as refrigerators. In recent years, in response to the market demand for energy saving or space-saving large-capacity, that is, increasing the internal volume in a limited space by making the insulation wall thinner, vacuums that have better heat insulation performance than urethane foam materials have begun to be used. A form in which heat insulating materials are buried in urethane foam and used together. This vacuum heat insulating material is also used in refrigerators and the like. [0003] Generally, a vacuum heat insulating mater...
