Cooling Concepts
AB CHILLCORE POUCH COOLER (TOP / BOTTOM)
The AB Chillcore™ pouch cooler for top and bottom cooling is designed for direct contact with battery cells, ensuring efficient heat transfer across the full cell surface. Its flexible structure adapts to dimensional variations and compensates for cell tolerances, maintaining consistent thermal performance. By optimizing surface contact and eliminating the need for gap fillers, the solution supports simplified system design and improved thermal efficiency.
AB CHILLCORE POUCH COOLER (SIDE COOLER)
The AB Chillcore™ side cooler enables reliable thermal management under dynamic operating conditions by applying controlled compression during cell expansion and contraction. It maintains a high coolant flow rate even under compression, ensuring consistent cooling performance. Its compact design supports high energy density battery packs while replacing conventional gap fillers and enabling more efficient use of available space.
AB CHILLCORE RIGID COOLER (Al Cooler)
The AB Chillcore™ rigid aluminum cooler provides a robust solution for advanced battery systems, combining structural stability with precise thermal management. It compensates for cell swelling and breathing effects while enabling controlled and efficient fluid flow. By integrating cooling and structural functions, the design eliminates the need for additional gap fillers and contributes to a more streamlined system architecture.
AB CHILLCORE PROFILE COOLER (IMMERSION COOLING)
The AB Chillcore™ profile cooler is specifically designed for immersion cooling applications, enabling precise control of the coolant flow field for uniform temperature distribution. It offers compatibility with various dielectric fluids, including oil-based systems, and supports flexible application requirements. With a compact design that reduces space requirements and simplifies assembly, the solution eliminates gap fillers and enables efficient integration into next-generation battery systems.
