Battery Pack Tray With Hidden Cooling Tube Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack trays have exposed connecting members that are prone to corrosion and leakage, compromising the reliability of the cooling system.
Innovation Solution
A tray design that includes a bottom plate with integrated flow channels, a frame, and an adapter piece that protects connection portions, allowing for hidden connections and reduced size, while ensuring consistent cooling and reduced flow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting member is exposed out of the tray, then the installation and maintenance are easier, but the reliability deteriorates due to corrosion and leakage risks
Solution Approach 1:
The connecting member is nested within the tray body, forming a hidden connection structure where the connecting member is received in a receiving cavity of the tray, protecting it from external corrosion and collision while maintaining functional accessibility
Solution Approach 2:
The tray body acts as a protective shell enclosing the connecting member, providing corrosion resistance and mechanical protection while allowing fluid flow through integrated channels
2Ease of operation
If the connecting member is exposed out of the tray, then the connection access is better, but the risk of collision and leakage increases
Solution Approach 1:
The connecting member is nested within the tray body, forming a hidden connection structure where the connecting member is received in a receiving cavity of the tray, protecting it from external corrosion and collision while maintaining functional accessibility
Solution Approach 2:
The tray body provides pre-established protective enclosure around the connecting member, preventing harmful factors like corrosion and collision before they can affect the connection reliability
3Reliability
If the adapter piece connections are hidden in the side beam, then the reliability improves by protecting connections, but the device complexity increases
Solution Approach 1:
The tray body integrates multiple functions including structural support, fluid distribution through channels, and protection of connecting members, merging what would otherwise be separate components into a unified structure
Solution Approach 2:
The tray body serves multiple purposes: it provides the cooling channel structure, acts as a protective enclosure for connecting members, and maintains structural integrity of the battery pack, reducing the need for additional protective components

AI summary
A tray (200) and a battery pack (1000) having the same are provided. The tray includes a bottom plate (2), a frame (3), an external connecting tube (5) and an adapter piece (4). The frame includes a first side beam (32), where a first accommodating groove (321) is formed on the first side beam. An inner end of the external connecting tube extends into the first side beam. the adapter piece includes a first connecting portion (41) and a second connecting portion (42), where the first connecting portion is connected to the bottom plate, and the second connecting portion is connected to the inner end of the external connecting tube. the adapter piece is accommodated in the first accommodating groove, to allow the first connecting portion and the second connecting portion to be hidden in first side beam.
