Vacuum Insulation Panel Groove Structure for Smooth Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum insulation panels face issues with smoothness and thermal conductivity deterioration due to the placement of absorbents, which can lead to pinhole generation and poor sealing, causing a decline in insulation performance.
Innovation Solution
The absorbent securing part is formed by cutting the core material in a shape and depth corresponding to the absorbent's dimensions, allowing for a groove-like structure that secures the absorbent and prevents peripheral pressing, thereby enhancing smoothness and maintaining consistent thermal conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the absorbent is placed above the core material or between the core materials, then the absorbent can be secured to maintain vacuum, but the smoothness of the vacuum insulation panel is lowered causing pinhole generation and poor sealing
Solution Approach 1:
The core material is cut to create a localized groove structure at the specific position where the absorbent needs to be placed. This local modification allows the absorbent to be securely held in a depression while the rest of the panel surface remains smooth and flat, resolving the contradiction between vacuum maintenance reliability and manufacturing precision for smoothness.
2Reliability
If an absorbent securing part is provided by cutting some portion of the core material, then the absorbent can be secured, but the density of the core material is reduced at the portion causing partial deterioration of thermal conductivity
Solution Approach 1:
Instead of removing large portions of the core material, only minimal cutting is performed to create shallow grooves just deep enough to hold the absorbent. This partial action secures the absorbent while minimizing the reduction in core material density and volume, thereby reducing the impact on thermal conductivity performance.
3Manufacturing precision
If the core material is cut to secure the absorbent, then the absorbent can be positioned accurately, but the structural integrity and density of the core material are compromised
Solution Approach 1:
The cutting is performed locally only at the positions where absorbents need to be placed, creating isolated grooves rather than extensive cuts. This localized approach achieves accurate absorbent positioning while minimizing the overall impact on the structural integrity and density of the core material.

AI summary
Disclosed are a vacuum insulation panel, a method for manufacturing the same and an insulation box having the same. By cutting the core material correspondingly to shape and thickness of the absorbent without cut of the core material and pressing the absorbent securing part to form the groove for placing the absorbent therein, the vacuum insulation panel prevents partial deterioration of heat transmission caused by the cutoff of the core material or deterioration of the smoothness caused by placing the absorbent above the core material or between the core materials. Particularly, it is possible to prevent the phenomenon that the periphery is pressed together, which is shown in a conventional press process, to thereby improve the smoothness by cutting the core material in shape and depth corresponding to the shape and thickness of the absorbent prior to the press of the absorbent securing part. Therefore, it is possible to provide an energy saving insulation box by reducing generation of wrinkle or poor sealing of the surface material of the vacuum insulation panel to thereby increase insulation efficiency of the vacuum insulation panel for a long time.
