Numerical analysis of heat transfer from perforated fins of an induction motor housing

Abstract

The major goal of this research article is to demonstrate how perforation on the fin surface of an induction motor’s housing improves cooling performance. Heat transfer study was also conducted between traditional fins and the suggested perforated fins housing. An Induction Motor (IM) overheats as a result of continuous operation, raising its temperature, lowering its performance and shortening its lifespan. The innovative designs and development of fins are necessary for effective cooling and enhancing the thermal performance of IM. In the present work, the thermal analysis of induction motor is carried out by means of providing the perforations on existing fins and varying perforation size from 4 mm to 10 mm diameters and number of perforation from 20 to 11, on fins and observed the steady state heat transfer and temperature variation. In this regard, the half part of IM is modelled because of symmetry and steady state thermal analysis is carried out for un-finned, solid fins and perforated fins using ANSYS software. Results show that, more reduction in temperature on the surface of IM is observed in case of perforated fins having 11 perforations of 10 mm diameter, as compared to the other cases.
