Abstract
Effective thermal management in hybrid electric vehicles (HEVs) is crucial for improving performance, safety, and durability of the vehicle’s powertrain components. This manuscript presents a comprehensive comparative analysis of different cooling techniques used in HEVs, including liquid cooling, air cooling, and phase change material (PCM)-based cooling systems. The study evaluates these methods based on heat dissipation efficiency, weight, cost, complexity, and system reliability. Simulation-based research using validated thermal models assesses the temperature distribution and cooling performance under various operating conditions. Statistical analysis quantifies the effectiveness of each technique, providing valuable insights for optimal thermal management strategies in hybrid vehicles. Results demonstrate that liquid cooling offers superior thermal control, whereas PCM-based systems provide benefits in passive cooling applications. The findings aim to guide engineers and researchers in selecting appropriate thermal management solutions to enhance HEV performance within current technological constraints.
