Abstract

A thermal management system for a battery pack includes a plurality of main bodies disposed in a stack, an inlet conduit and an outlet conduit in fluid communication with the plurality of main bodies, and a retention panel coupled to the plurality of main bodies. The main bodies include a thermal fin and conduit and are formed using an extrusion process, which minimizes a weight of the thermal fin and heat sink while minimizing a cost of the thermal management system.
