Vacuum Insulation Panel Groove Structure for Absorbent Securing
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 over time.
Innovation Solution
The absorbent securing part is formed by cutting and shaping the core material to match the absorbent's dimensions, creating a groove that secures the absorbent, thereby preventing peripheral pressing and maintaining even density, thus enhancing smoothness and 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, but the smoothness of the vacuum insulation panel is lowered and pinholes may generate in the surface material
Solution Approach 1:
The core material is cut to create a localized groove structure that specifically accommodates the absorbent in a defined region, while the rest of the core material maintains its original smooth surface structure. This local modification approach secures the absorbent without compromising the overall smoothness of the panel surface.
2Reliability
If an absorbent securing part is provided by cutting some portion of the core material, then the absorbent can be placed, but the density of the core material is reduced at the portion corresponding to the absorbent securing part to cause partial deterioration of thermal conductivity
Solution Approach 1:
A groove structure is created in the core material that forms a containment space for the absorbent. The groove walls act as flexible boundaries that secure the absorbent through the structural configuration of the core material itself, eliminating the need for additional securing components that would further reduce density and thermal performance.
3Reliability
If the absorbent is placed in a groove formed by cutting the core material, then the absorbent is secured, but the smoothness may still be affected and wrinkle generation may occur
Solution Approach 1:
The groove is pre-formed in the core material before the absorbent is placed, creating a predetermined securement structure. This preliminary preparation ensures that the absorbent fits precisely into the groove without causing displacement or wrinkling of the surface material during assembly, thereby maintaining surface smoothness while achieving reliable absorbent securing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach improves the smoothness and long-term insulation efficiency of vacuum insulation panels by reducing wrinkle and poor sealing issues, maintaining high thermal performance and energy savings.
Implementation Method 1
the securing part of the core material is formed by cutting the core material in shape and depth corresponding to the shape and thickness of an absorbent and pressing the cut portion
Implementation Method 2
has a considerably reduced thermal conductivity of a gas by keeping an inside of the insulation panel in vacuum
Implementation Method 3
inclusion of an absorbent such as silica gel, calcium oxide and zeolite has been suggested

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.
