Split Heat Exchange Tube Connector for Battery Pack Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat exchange pipe joints in battery packs are typically one-piece, making them difficult to repair or replace due to the limited space within the battery pack, requiring the detachment of other components for removal.
Innovation Solution
A split-structure heat exchange pipe joint design where the first and second pipes are separately formed and detachably connected to the installation plate, allowing for easy detachment and installation without removing internal components, utilizing a through-hole and sealing members for secure and leak-proof connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a one-piece heat exchange pipe joint is used, then the structural integrity is improved, but the ease of repair deteriorates due to the inability to detach the joint without removing other components
Solution Approach 1:
The heat exchange pipe joint is divided into multiple separable parts: a first pipe connected to the installation plate, a second pipe with a second flange, and connection components. This segmentation allows each part to be independently detached and replaced without removing the entire joint assembly, resolving the contradiction between structural integrity and ease of repair.
2Ease of manufacture
If a one-piece heat exchange pipe joint is used, then the manufacturing process is simplified, but the operation space required for detachment increases
Solution Approach 1:
By segmenting the joint into separate pipe components with standardized connection interfaces (flanges, sealing members), the design maintains manufacturing simplicity while enabling detachment operations to be performed in limited spaces. Each segment can be independently manipulated without requiring large clearance, thus resolving the contradiction between ease of manufacture and ease of operation.
3Ease of repair
If a split-structure heat exchange pipe joint is used, then the ease of repair is improved, but the device complexity increases due to multiple separate components
Solution Approach 1:
The joint is segmented into essential functional components (first pipe, second pipe, flanges, sealing members) that are necessary for the heat exchange function. This segmentation enables easy repair by allowing replacement of only the faulty segment, while the overall device complexity remains controlled because the number of components is minimized to only those required for the core function.
Solution Approach 2:
The connection components (flanges, sealing members, fastening structures) are designed with universal functionality to accommodate different pipe configurations and repair scenarios. This multi-functionality reduces the need for specialized parts, thereby controlling device complexity while maintaining ease of repair.

AI summary
The present disclosure provides a heat exchange pipe joint and a battery pack. The heat exchange pipe joint is fixedly installed to an installation plate. The heat exchange pipe joint includes a first pipe and a second pipe that are separately formed and in communication with each other. The first pipe is detachably connected to a second side of the installation plate, and the second pipe is detachably connected to a first side of the installation plate. When the heat exchange pipe joint of the present disclosure is applied to the battery pack, the heat exchange pipe joint in a split-structure requires a small operation space for detachment and installation. In this case, a process of taking out the entire heat exchange pipe joint from the case can be avoided, so that the battery module and other components inside the case do not interfere with the detachment and installation of the heat exchange pipe joint. In this way, the detachment and installation of the heat exchange pipe joint can be easy and convenient, thereby facilitating the reparation process thereof.
