C-Channel Enclosed Vacuum Insulation Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum insulated panels used for temperature-sensitive goods suffer from reduced thermal performance due to the fragile nature of their gas-tight outer film, which is prone to abrasion and impact damage, leading to frequent loss of vacuum and insulating value.
Innovation Solution
The use of C-channel binding bars and wear-protective cover sheets to enclose frangible thermal insulation panels, providing protection against abrasion and impact while maintaining thermal insulation integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If vacuum insulated panels are used for temperature-sensitive goods, then thermal insulation performance is improved, but the outer film is prone to abrasion and impact damage
Solution Approach 1:
The protective system is divided into multiple components: C-channel binding bars that enclose the edges and corners of the panel, and separate wear protective cover sheets that protect the major surfaces. This segmentation allows each component to be optimized for its specific protective function while collectively providing comprehensive protection to the vacuum insulated panel.
Solution Approach 2:
The C-channel binding bars and cover sheets act as intermediary protective elements between the fragile vacuum insulated panel and the external environment. These intermediaries absorb and distribute impact forces and prevent direct contact between damaging external factors and the panel's outer film, thereby preserving the vacuum integrity.
2Reliability
If the outer film is made thin and flexible for sealing, then vacuum sealing is achieved, but protection against abrasion and impact is reduced
Solution Approach 1:
The C-channel binding bars and cover sheets are installed beforehand to cushion and protect the vulnerable outer film of the vacuum insulated panel. This pre-protective measure ensures that when abrasion or impact occurs, the damage is absorbed by the protective components rather than the critical vacuum seal, maintaining vacuum integrity despite external hazards.
3Strength
If protective structures are added to the panel, then abrasion and impact resistance is improved, but device complexity increases
Solution Approach 1:
The protective cover sheets are made from flexible, thin material that can conform to the panel surfaces while providing adequate protection. The C-channel binding bars use a simple C-shaped cross-section that is easy to manufacture and install. These design choices provide effective protection while minimizing the addition of structural complexity and maintaining ease of assembly.
