Thermal Reduction in Lithium-ion Power Source Using Multilayer Heat Sink Channels with Different Fluids as Coolant

Abstract

In this paper, finite element method (FEM) based modelling and simulation of the Lithium Ion Battery (LIB) is carried out with the mechanism of multilayer multichannel heat sink in it. The capability of four different fluid movement and flow pressure were analyzed in the design. Nitrogen, carbon dioxide, hydrogen, and Freon were taken as fluids for simulation. Among these fluids, nitrogen and carbon dioxide showed the highest movement in the channel. Results confirmed them as the better contender for the fluid as heat sink in channel based heat removal from the device.
