Corrugated fin and frame assembly for battery cooling

摘要

A cooling module for a battery pack assembly is disclosed. The cooling module includes a frame having a plurality of legs forming an opening through a central portion of the frame, at least one of the plurality of legs including a slot formed therethrough. A cooling fin is coupled to the frame. The cooling fin includes a corrugated plate interposed between a first plate and a second plate forming a plurality of fluid flow channels between the first plate and the second plate. The cooling modules are disposed in a stack having at least one battery cell disposed between adjacent cooling modules. The battery cell is in heat transfer communication with the cooling fin of at least one cooling module, wherein the cooling fin facilitates a transfer of heat energy between the battery cell and the flow channels formed in the cooling fin.
