Solution Overview
Problem
Existing superstructures for refrigerated transport vehicles face challenges in maximizing transport volume due to the need for thick thermal insulation, which increases energy costs and reduces the efficiency of cooling units, especially under varying climatic conditions.
Innovation Solution
A structure featuring vacuum insulation panels securely embedded between inner and outer cover layers using adhesive layers and foam support elements, allowing for a fixed position and enhanced protection, thereby improving thermal insulation and reducing heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thick-walled thermal insulation layers are used to improve thermal insulation, then thermal insulation efficiency is improved, but transport interior volume is reduced
Solution Approach 1:
The patent changes the physical state and density parameters of the insulation material by using vacuum insulation panels (VIPs) with vacuum-evacuated cores. This parameter change enables achieving superior thermal insulation performance (lower heat transfer coefficient) with significantly reduced material thickness, thereby maintaining transport interior volume while improving thermal insulation efficiency.
Solution Approach 2:
The patent employs composite material structures combining vacuum-evacuated cores with outer skin layers and edge sealants. This composite approach creates a multi-layer vacuum insulation panel system that achieves high thermal insulation performance with minimal thickness, resolving the contradiction between insulation efficiency and transport volume.
2Loss of energy
If conventional thermal insulation elements are used to improve thermal insulation, then thermal insulation is improved, but cooling unit energy requirement increases
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional solid foam insulation to vacuum insulation panels with evacuated cores. This parameter change dramatically reduces the heat transfer coefficient, thereby reducing the thermal load on cooling units and lowering their energy requirements during transport operations.
3Loss of energy
If vacuum insulation panels are embedded in plastic foam to improve thermal insulation, then thermal insulation is improved, but position-fixed arrangement becomes more difficult
Solution Approach 1:
The patent applies preliminary action by pre-attaching support corset elements to the vacuum insulation panels before final installation. This preliminary structuring provides inherent positional stability and mechanical support, making the subsequent embedding process in adhesive layers more straightforward and ensuring precise position-fixed arrangement without requiring complex foam embedding procedures.
