This paper investigates the feasibility of a direct liquid cooling technique for the thermal management system of an electrical machine for automotive application. The cooling system is a closed liquid coolant loop employing a mixture of Ethylene Glycol and water as a coolant. General performance of the cooling system at different volume fractions of mixture of Ethylene Glycol and water is evaluated. Various geometry of the cooling system, and physical characteristics of the coolant fluid are studied. Thermal analyses of the cooling system are performed using computational fluid dynamics and 3D turbulent fluid motion analysis. According to analysis, influence of the critical parameters on the performance of the cooling system is studied.

Abstract

This paper investigates the feasibility of a direct liquid cooling technique for the thermal management system of an electrical machine for automotive application. The cooling system is a closed liquid coolant loop employing a mixture of Ethylene Glycol and water as a coolant. General performance of the cooling system at different volume fractions of mixture of Ethylene Glycol and water is evaluated. Various geometry of the cooling system, and physical characteristics of the coolant fluid are studied. Thermal analyses of the cooling system are performed using computational fluid dynamics and 3D turbulent fluid motion analysis. According to analysis, influence of the critical parameters on the performance of the cooling system is studied.
