Compressible Cooler Plate Contact for Battery Module Cooling

The patent changes the rigidity parameter of the cooler by selecting materials with lower rigidity (such as aluminum or aluminum alloys) compared to the lower case. This parameter change allows the cooler to deform and conform to the outer surface of the lower case, achieving close thermal contact while maintaining structural stability through the force exerting portions.

The patent introduces force exerting portions (such as elastic members, resilient members, or biasing members) that dynamically adjust the position and contact pressure of the cooler against the lower case. These dynamic elements allow the cooler to maintain close contact while accommodating variations in the lower case surface, thereby resolving the contradiction between conformability and structural stability.

The patent employs flexible force exerting portions such as elastic members, resilient members, or thin-walled structures that can deform to conform the cooler to the lower case surface. These flexible elements achieve close thermal contact without requiring complex rigid mechanical systems, thereby reducing overall device complexity while maintaining contact precision.

The force exerting portions are designed to automatically adjust and maintain contact between the cooler and the lower case without requiring external control systems. The elastic or resilient nature of these members allows them to self-regulate their force application, eliminating the need for additional sensors, actuators, or control mechanisms, thus avoiding increased device complexity.
