Stuttgart, Germany - July 8, 2026 - Automotive thermal management specialist MAHLE has partnered with semiconductor manufacturer Infineon Technologies to develop a high-performance electronic cooling unit for power modules used in AI data center applications, addressing the growing thermal challenges associated with next-generation computing infrastructure.
The jointly developed solution is designed for Infineon's new EasyPACK™ S power module, which controls electric switchgear and power distribution functions in applications such as data center power supply systems. As AI workloads continue to increase server rack power densities, efficient thermal management has become a critical factor in improving the performance, reliability, and lifespan of power electronics that support mission-critical infrastructure.
MAHLE's cooling unit is mounted directly onto the circuit board, where it dissipates heat generated by the power module using liquid coolant. Although compact, roughly the size of two stacked chocolate bars, the system significantly enhances the module's cooling performance compared with previous generations. According to the companies, the improved heat dissipation enables higher operating performance while extending the durability and functional life of the semiconductor components.
The development was completed in just four months, with MAHLE delivering the prototypes to Infineon for testing and validation. The rapid development timeline reflects growing collaboration between thermal management specialists and semiconductor companies as AI infrastructure drives demand for increasingly efficient power delivery technologies.
While MAHLE has traditionally focused on automotive thermal systems, the project highlights the company's broader strategy of expanding into industrial and digital infrastructure markets. The company recently consolidated its non-automotive activities under a dedicated Industrial and Special Solutions business unit, allowing it to adapt expertise developed for electric vehicles to sectors including data centers, industrial electronics, and energy systems.
For data center operators, advances in component-level cooling are becoming increasingly important as AI clusters consume more power and generate greater heat than conventional enterprise servers. High-performance semiconductors used in switchgear, power conversion equipment, and server power supplies must operate within strict thermal limits to maintain efficiency and ensure uninterrupted operation. As rack power continues to climb, improvements in cooling at the component level can contribute to higher system reliability and lower operational costs.
The collaboration also underscores the evolving relationship between the automotive and data center industries. Technologies originally developed to manage heat in electric vehicles are increasingly finding applications in AI infrastructure, where compact, high-efficiency cooling solutions are essential for supporting dense computing environments. As data centers continue to scale to meet surging AI demand, innovations in thermal management are expected to play a pivotal role in enabling more efficient and resilient power systems.
The MAHLE-Infineon project reflects a broader industry trend toward optimizing every layer of AI infrastructure, from chips and power electronics to facility cooling, as operators seek to maximize performance while managing the rising energy demands of next-generation data centers.
