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, corner elements for stacking, anchoring portions for attachment, and a frame structure formed by corner elements and side parts. This innovative design allows for efficient cooling of cells in a stack while providing structural support and flexibility for assembly.

Furthermore, the patent also covers the application of these cooling modules in a cell stack, particularly for accumulator cells. The design ensures that the carrier elements form a continuous side wall of the housing encasing the cells and cooling elements, maintaining structural integrity and thermal management. Additionally, the inclusion of end plates with clamping plates at both ends of the stack allows for secure clamping of the carrier elements together. Overall, this patented technology offers a comprehensive solution for cooling and housing cell stacks, enhancing performance and reliability in various applications requiring efficient thermal management.
