A recently granted patent (Publication Number: US11923524B2) discloses a cooling module designed for a cell stack, featuring a unique carrier element made of injection-molded plastics that surrounds and supports a cooling element. The carrier element includes elastic compensation regions, undulating outer wall portions, and anchoring portions for secure attachment to the cooling element. Additionally, the carrier element can be stacked on top of each other using stacking regions with reinforcing elements and clamping portions, allowing for efficient cooling of multiple cells within a cell stack.

Furthermore, the patent describes a cell stack, such as an accumulator cell stack, incorporating the cooling modules. The cell stack includes a series of cells and cooling modules that form a side wall of a housing encasing the cells and cooling elements. The design ensures uninterrupted cooling and structural integrity by utilizing end plates as clamping plates to secure the stacked carrier elements. The innovative cooling module and cell stack configuration provide an efficient and reliable cooling solution for various applications requiring temperature management in a stackable and secure manner.
