EXTRUDED THERMAL FIN FOR TEMPERATURE CONTROL OF BATTERY CELLS
First Claim
Patent Images
1. A thermal management system for a battery pack:
- at least one battery cell; and
a main body having a battery cell retention area formed between a plurality of thermal fins and a first conduit in fluid communication with a source of a fluid, the first conduit in thermal communication with the thermal fins, wherein the at least one battery cell is received in the battery cell retention area to place the thermal fins in thermal communication with the at least one battery cell, and wherein the fluid is caused to flow through the first conduit and cooperates with the first conduit and the thermal fins to regulate a temperature of the at least one battery cell.

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.
