VACUUM THERMAL INSULATING MATERIAL, THERMAL INSULATING CAMERA AND METHOD OF MANUFACTURE OF VACUUM THERMAL INSULATING MATERIAL Russian patent published in 2018 - IPC F16L59/65 

FIELD: refrigerating equipment.

SUBSTANCE: group of inventions refers to the production of heat-insulating products for their use in refrigeration equipment. It is an object of the present invention to provide an evacuated heat-insulating material, a heat-insulating chamber and a method for manufacturing an evacuated heat-insulating material, where a high-permeability wrapper material is used to increase the rate of gas absorption within the evacuated heat-insulating material and improve the thermal insulation characteristics. Vacuum insulated thermal insulation material (1) contains: core material (10) made from a complex of fibers; adsorbent (30) which adsorbs at least water; and outer wrapping material (20) that covers core material (10) and adsorbent (30). Inside of outer wrapping material (20) is evacuated and hermetically sealed. Adsorbent (30) is wrapped with wrapping material (31) for adsorbent (30) without using heat sealing. As wrapping material (31) only Japanese parchment is used.

EFFECT: vacuumed heat-insulating material, a heat-insulating chamber and a method for manufacturing an evacuated heat-insulating material are proposed.
