Parametric Study on Enhanced Thermal Management via Regulated Impingement Boiling Cooling

Résumé

This study comprehensively investigates impinging jet cooling mechanisms within a thermal regulation framework. Utilizing an innovative cooling approach based on the Smart Element of Cooling with impinging jets and transverse airflow, a 3D numerical model based on the Inverse Heat Conduction

Problem (IHCP) is developed. This model quantifies heat exchange distribution at the wall of a confined cylindrical space with a margin of error below 3%. The study demonstrates the effectiveness of a regulation algorithm in maintaining target cooling rates, highlighting significant influences of jet aerodynamic and hydraulic parameters, such as flow rate ratios, jet orientation, size, and distribution on cooling performance. The research aims to define the optimal jet configuration for efficient heat dissipation while maintaining precise temperature control and enhanced cooling uniformity. Optimal configurations are found to depend on desired cooling rates and ratio combinations. For average cooling rates around 15°C/min, a spacing ratio of 30 between jets, a hydraulic diameter ratio of 7.5, and a flow ratio of 4 appear optimal for achieving enhanced cooling uniformity. These configurations present promising prospects for designing more efficient cooling systems in various industrial applications, thereby enhancing manufacturing process performance.
