Parametric Modeling and Airflow Analysis of a Lithium-Ion Battery Drying Oven

The oven is a critical component in lithium-ion battery coating equipment, and its customized design often involves repetitive modeling tasks and long development cycles. This study proposes an integrated process-parameter-driven framework for parametric CAD (Computer Aided Design) modeling and automated assembly of side-air-inlet drying ovens based on the secondary development of SolidWorks. Relationships between key process parameters and oven structural parameters were established, and Visual Basic programming combined with the SolidWorks API (Application Programming Interface) was used to realize parametric component generation and automatic assembly. The proposed framework reduces repetitive modeling operations and improves model-generation efficiency. The automatically generated oven geometry was further transferred to a CFD (Computational Fluid Dynamics) workflow for airflow- and temperature-field evaluation. The CFD results captured the main characteristics of hot-air circulation, temperature distribution, and local airflow non-uniformity, demonstrating that the proposed framework provides a suitable geometric basis for subsequent CFD-based engineering analysis.
