Cooling Fins, Cooling Modules with Cooling Fins, and Battery Modules with Cooling Modules

Abstract

The present invention provides a cooling fin, a cooling structure including the cooling fin, and a battery module including the cooling structure, the cooling fin not requiring flatness of a heat transfer portion during processing or assembly Managed and adapted to distribute physical stresses occurring in response to the external environment to thereby minimize deformation of the heat transfer portion. The cooling fin according to the present disclosure includes: a body having a rectangular shape; a first extension protruding from an upper edge of the body and extending in one direction at right angles with respect to the body; The second extension part of the body extending in one direction in the form of steps, wherein the second extension part is divided into a plurality of slits.

Description

technical field [0001] The present invention relates to a cooling fin, a cooling module including the cooling fin and a battery module including the cooling module, the cooling fin does not require heat transfer parts contacting the surrounding structure during processing or assembly. Flatness management (ie, straightness management), and adapted to disperse physical stress occurring in response to the external environment, thereby minimizing deformation of the heat transfer portion. Background technique [0002] In recent years, vehicles are being manufactured based on research conducted to secure driving force using internal combustion engines and / or electric motors, thereby reducing air pollution from vehicle exhaust. Accordingly, vehicles have evolved in the order of hybrid vehicles, plug-in hybrid vehicles, and electric vehicles. In this case, hybrid vehicles and plug-in hybrid vehicles have an internal combustion engine, an electric motor, and a battery pack, and elec...

Problems solved by technology

This influence from external factors exerts physical stress on the heat transfer part so that the heat transfer part cannot maintain a rectangular shape in a flat state and deforms some areas of the heat transfer part

[0005] When the cooling fins and cooling plates or boxes are combined with each other, this deformation of the heat transfer part forms a gap between the cooling fins and the cooling plate, because the gap corresponds to some areas of the heat transfer part, so this deformation prevents The heat of the battery cells is quickly transferred from the cooling fins to the cooling plate

Furthermore, due to the increase in volume of the battery cell during charging or discharging of the battery cell, the cooling fins exert physical stress on the area contacting the battery cell, thereby causing deformation of the heat transfer portion when the battery cell is being used
