Trumony Unveils Integrated Liquid Cold Plate and Lower Enclosure for 587 Ah Battery Cells

Suzhou, China – March 26, 2026

Trumony Aluminum Develops Next-Generation Integrated Liquid Cooling Plate for 587 Ah Battery Cells

Trumony Aluminum Limited, a leading manufacturer of thermal management solutions for electric vehicles and energy storage systems (ESS), has announced the development of a next-generation integrated liquid cooling plate and lower enclosure (tray) specifically designed for the emerging generation of 587 Ah battery cells.

As the energy storage industry transitions from 280 Ah to higher capacities exceeding 500 Ah, thermal management and structural integrity have become critical factors in ensuring safety and longevity. The new 587 Ah cell format, aimed at achieving 6+ MWh energy density within standard 20-foot containers, imposes significant mechanical and thermal demands on battery pack components. Trumony’s latest solution addresses these challenges through a highly integrated approach.

Engineering for High-Density Applications

The newly designed component combines the structural role of the lower enclosure with the thermal dissipation function of a liquid cooling plate. By integrating these two elements, Trumony’s design optimizes the internal space required for high-density cell arrangements. The solution focuses on three key engineering principles:

• Structural Load Optimization: The enclosure is engineered to manage the increased gravitational and expansion forces generated by larger cells, providing robust support and vibration resistance for the entire pack.

• Integrated Thermal Management: The liquid cooling plate is embedded into the structural base, ensuring efficient heat dissipation. This design maintains uniform temperature across the cells, which is crucial for preventing thermal runaway and extending cycle life.

• Material Excellence: Utilizing high-grade aluminum alloys (such as 3003 and 6063), the product offers superior thermal conductivity while contributing to overall system lightweighting—a key factor in both automotive and stationary storage applications.

Advanced Manufacturing and Customization

Trumony leverages its extensive manufacturing footprint, to ensure precision and scalability. The company utilizes advanced welding techniques—such as brazing and friction stir welding—to guarantee the reliability of the cooling channels under high pressure.
