Optimized Water Jacket Pin-Fin design for Reducing Pressure Drop in Cooling System

Abstract:
In the electric vehicle and solar industries, the cooling performance of power conversion devices is a key factor in ensuring system stability and efficiency. Liquid cooling offers superior heat dissipation, but excessive pressure drop can reduce cooling efficiency. The pin-fin structure inside a water jacket enhances heat transfer; however, an unoptimized design may lead to excessive pressure drop. This study investigates the impact of pin-fin shape, count, and height on pressure drop and thermal performance using CFD simulations with EGW-50 coolant. The findings emphasize the importance of optimizing pin-fin design to achieve an optimal balance between pressure drop and cooling efficiency.
