Elastic Protective Sleeve for Bent Battery Cooling Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective sleeves for pipelines are difficult to install and remove, leading to low efficiency in production and assembly, particularly in battery thermal management systems where pipelines are often designed in bent shapes.
Innovation Solution
A protective sleeve with a sleeve body comprising a first bundling section, a first diameter-variable section, a protective section, a second diameter-variable section, and a second bundling section, where the bundling sections are elastic to securely clamp the pipeline, allowing easy installation and removal, and optionally featuring mechanical and fire protection layers for enhanced durability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional protective sleeves are used for pipelines, then protection function is provided, but installation and removal convenience deteriorates
Solution Approach 1:
The protective sleeve is divided into multiple sections with different functions: elastic bundling sections for clamping, rigid protective sections for protection, and diameter-variable sections for transition. This segmentation allows the sleeve to be easily installed by stretching the elastic sections while maintaining protection functionality.
Solution Approach 2:
The protective sleeve incorporates elastic fiber bundles that provide dynamic expansion and contraction capabilities. The elastic bundling sections can be stretched during installation and automatically clamp onto the pipeline, enabling quick installation and removal without permanent deformation.
2Ease of operation
If protective sleeve with elastic bundling sections is used, then installation convenience is improved, but structural complexity increases
Solution Approach 1:
The protective sleeve integrates multiple functions into a single structure: the elastic bundling sections provide both the expansion mechanism for easy installation and the clamping force for secure fixation. The rigid protective sections provide mechanical protection while the diameter-variable sections provide structural transition, eliminating the need for separate components.
Solution Approach 2:
The protective sleeve uses a flexible woven structure composed of rigid protective fibers and elastic fiber bundles. This flexible shell design allows the sleeve to expand and contract during installation while maintaining structural integrity and providing protection when installed.
3Reliability
If protective sleeve is designed for secure clamping, then fixation reliability is improved, but removal difficulty increases
Solution Approach 1:
The elastic fiber bundles in the bundling sections can be periodically compressed and expanded. During installation, they are stretched to expand the sleeve and then release to clamp securely. During removal, they are compressed to release the clamping force, allowing easy removal while maintaining secure fixation during operation.

AI summary
A protective sleeve, a battery thermal management system, and a battery are provided. The protective sleeve is configured to sleeve a pipeline and includes a sleeve body, where the sleeve body includes a first bundling section, a first diameter-variable section, a protective section, a second diameter-variable section, and a second bundling section arranged in sequence. Diameters of the first bundling section and the second bundling section are smaller than diameter of the protective section, and the first bundling section and the second bundling section are capable of elastically clamping the pipeline, so as to fix the protective sleeve to the pipeline. This can improve the convenience of installing and removing the protective sleeve on the pipeline.
