Title:
HEAT INSULATION STRUCTURE AND MANUFACTURING METHOD OF HEAT INSULATION STRUCTURE
Document Type and Number:
Japanese Patent JP2022001771
Kind Code:
A
Abstract:
To provide a heat insulation structure which can improve heat insulation performance while suppressing an increase of a thickness, and can suppress a rise of a surface temperature of a vacuum heat insulation material.SOLUTION: A heat insulation structure 100 comprises: a vacuum heat insulation material 130 having a core material and an outer cover material for covering the core material while vacuuming and sealing it; a first foaming heat insulation material 110 which is arranged while tightly adhering to the vacuum heat insulation material 130 at one side face, and in which a recess 111 is formed at one side face; and a second foaming heat insulation material 120 which is arranged while covering the vacuum heat insulation material 130 and the first foaming heat insulation material 110. An air heat insulation layer 101 formed of air which is sealed in the recess 111 is formed at the first foaming heat insulation material 110. The air heat insulation layer 101 is arranged at a high-temperature heat source side rather than the vacuum heat insulation material 130.SELECTED DRAWING: Figure 2
