Solution Overview
Problem
Traditional refrigeration appliance doors with heat insulation glass modules often experience condensation issues due to inadequate heat insulation, which compromises their performance.
Innovation Solution
A heat insulation door design featuring a vacuum glass module with overlapping glass plates and inert gas layers between them, along with additional glass plates for decoration and protection, enhances insulation and prevents condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat insulation glass module is used in the refrigeration appliance door, then the user can observe the interior without opening the door, but condensation occurs on the door surface due to insufficient heat insulation effect
Solution Approach 1:
The door body is divided into multiple glass plates (first glass plate, second glass plate, third glass plate) separated by vacuum layers and inert gas layers. This segmentation creates multiple thermal barriers that collectively enhance heat insulation performance and prevent condensation on the door surface.
Solution Approach 2:
Vacuum layers and inert gas layers are introduced as intermediary substances between the glass plates. These intermediaries have low thermal conductivity, effectively blocking heat transfer and preventing the door surface temperature from dropping to the dew point, thereby eliminating condensation.
2Object-affected harmful factors
If multiple glass plates with vacuum and inert gas layers are used to improve heat insulation, then condensation is prevented, but the door structure becomes more complex
Solution Approach 1:
Multiple functional layers (glass plates, vacuum spaces, inert gas layers, sealing portions) are merged into a single integrated door assembly. This combination achieves effective condensation prevention while maintaining structural unity and simplifying installation and maintenance procedures.
Solution Approach 2:
The door employs a composite structure combining different materials (glass, vacuum, inert gas) with complementary properties. Each material contributes specific functions: glass provides structural strength and transparency, vacuum and inert gas provide thermal insulation, and sealing portions provide structural integrity and sealing.
