Flex and JetCool Team Up with Broadcom for Advanced AI Thermal Management Solutions

Flex and JetCool Partnership Enhances AI Thermal Solutions

On March 11, 2026, Flex’s subsidiary JetCool announces an important collaboration with Broadcom aimed at developing advanced liquid cooling solutions tailored for next-generation AI processing units (XPUs). As demand for artificial intelligence capabilities escalates, the thermal management of silicon devices faces significant challenges due to rapidly increasing power densities, which can reach multi-kilowatt levels. JetCool’s novel single-phase direct-to-chip cooling technology directly addresses this issue, effectively managing heat flux levels of up to 4 W/mm² during multi-kilowatt ASIC operations. This partnership signifies a critical step toward enhancing the performance and reliability of AI platforms amid rising operational demands.

The collaboration between JetCool and Broadcom integrates sophisticated design elements across silicon architecture, advanced packaging, and thermal engineering. This unified approach promotes efficient development and manufacturing processes for AI hardware, ensuring optimal operational conditions for high-performance silicon. Ken Kutzler, vice president of AI Systems Development at Broadcom, underscores the urgency of synchronizing thermal management with silicon design as AI applications advance. By facilitating efforts that optimize both areas from the outset, the partnership accelerates the timeline for bringing innovative AI XPUs to market.

With Flex’s extensive manufacturing capabilities and JetCool’s pioneering cooling technology, the partnership reinforces the industry’s capacity to meet the thermal constraints imposed by complex AI silicon designs. According to Bernie Malouin, VP of Liquid Cooling at Flex, JetCool's contributions are vital for sustaining the performance of high-density ASIC platforms, ensuring the viability of future generations of AI silicon. As power densities elevate, the collaborative efforts between JetCool and Broadcom stand as a crucial response to the evolving needs of hyperscale AI infrastructures, paving the way for more resilient and efficient AI technologies.

In addition to the JetCool collaboration, Broadcom is simultaneously making waves with the release of a cutting-edge high-speed networking chip designed for AI data centers. This chip significantly enhances the efficiency of data transfers, a necessity in an era where rapid data processing is increasingly critical for AI applications. Broadcom's foray into efficient data handling strategies offers a glimpse into its commitment to staying at the forefront of technological developments in AI infrastructure.

As organizations continue to leverage artificial intelligence across diverse sectors—from automotive to finance—the combined efforts of JetCool, Flex, and Broadcom spotlight a transformative shift in thermal management and data processing capabilities essential for the ongoing evolution of AI technologies.
