HEAT INSULATION STRUCTURE AND COLD STORAGE HAVING THE SAME

Title:

HEAT INSULATION STRUCTURE AND COLD STORAGE HAVING THE SAME

Document Type and Number:

Japanese Patent JP2019086269

Kind Code:

A

Abstract:

To restrict the deformation of the opposed wall of a vacuum panel while maintaining the insulation effectiveness.SOLUTION: In a sealed space 40A of a vacuum panel 42 in a heat insulation structure 40, a rib structure 50 is provided, and the rib structure 50 includes a plurality of honey-comb ribs 50A in which the thickness direction of the vacuum panel 42 is the height direction. Therefore, when a pair of opposed walls 44 of the vacuum panel 42 try to be displaced toward the sealed space 40A, the pair of opposed walls 44 press both ends in the height direction of the honey-comb rib 50A so as to push each other via the honeycomb rib 50A. Thereby, the displacement to the sealed space 40A side of the pair of opposed walls 44 in the vacuum panel 42 can be suppressed. Moreover, the rib structure 50 is made of pulp material. Therefore, the thermal conductivity of the rib structure 50 can be made relatively low. Thereby, the heat insulation effect of the heat insulation structure 40 can be maintained.SELECTED DRAWING: Figure 1
