Method for manufacturing heat insulation housing

Abstract

To provide a method for manufacturing a heat insulation housing that prevents deterioration in material yield and generation of post-processing work and does not waste a material.SOLUTION: A method for manufacturing a heat insulation housing includes the steps of: measuring external dimensions of a vacuum heat insulation panel 5; assembling an outer box 3 inside which the vacuum heat insulation panel 5 is attached and an inner box 2 forming a space across the outer box 3 and the vacuum heat insulation panel 5; and injecting a heat insulation foam material 6 into the space in accordance with a volume of the vacuum heat insulation panel 5 on the basis of the measured external dimensions.SELECTED DRAWING: Figure 7
