Cold Storage Container Inner Fin Positioning Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In typical cold storage heat exchangers, the corrugated inner fin within the cold storage medium container can obstruct the filling process, leading to inefficiencies and difficulties in fully filling the container with the cold storage medium, thereby reducing productivity.
Innovation Solution
The cold storage medium container features a configuration where the peripheral edge portions of container members are brazed to form a filling opening, with an inner fin positioned using engagement projections that create gaps between the fin's corrugated end surfaces and the container walls, facilitating smooth filling by acting as a passage for the medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a corrugated inner fin is disposed within the cold storage medium container to increase strength, then the container strength is improved, but the inner fin becomes an obstacle preventing smooth filling of the cold storage medium
Solution Approach 1:
The inner fin is segmented into multiple sections along its length, with gaps between the corrugated portions. This segmentation allows the cold storage medium to flow through the fin structure during filling, eliminating the obstacle effect while maintaining the structural reinforcement function of the fin.
Solution Approach 2:
The gaps between the corrugated portions of the inner fin act as intermediary passages that facilitate the flow of cold storage medium through the fin structure. These gaps serve as channels that mediate between the obstruction caused by the fin and the need for smooth filling, allowing the medium to pass through rather than being blocked.
2Device complexity
If the inner fin is positioned without proper engagement structure, then the container structure is simpler, but the filling process becomes inefficient and incomplete
Solution Approach 1:
The engagement protrusions are pre-formed on the inner fin and the engagement grooves are pre-formed on the container body walls before assembly. This preliminary action ensures that when the fin is inserted, it automatically engages at the correct position, creating the necessary gaps for medium flow without requiring complex adjustment mechanisms during the filling process.
Solution Approach 2:
The inner fin structure includes self-aligning engagement features (protrusions and grooves) that automatically position the fin correctly within the container during assembly. This self-service mechanism eliminates the need for external positioning devices or complex alignment procedures, maintaining structural simplicity while ensuring optimal filling conditions.

AI summary
In order to provide a cold storage medium container that can be smoothly and reliably filled with a cold storage medium to thereby increase productivity. In a cold storage medium container 5, a body of the container 5 constituted of a pair of container members 10 and 12, and the body has an inner fin 11 therein and is filled with the cold storage medium through a cold storage medium filling opening 20 at an end of the body therein. Furthermore, in the cold storage medium container, an engagement portion 13 projects toward inside of the body to engage a part of a corrugated end surface at each end of the inner fin 11, to thereby position the inner fin 11 in the body, and a gap is disposed between the end surface at each end of the positioned inner fin 11 and an inner wall of the body.
