JetCool and Flex: Scaling Liquid Cooling Solutions Globally

06 March 2025

As artificial intelligence (AI) and high-performance computing (HPC) workloads push the limits of traditional data centers, the need for scalable, efficient cooling has never been greater. Flex, a global leader in manufacturing and supply chain solutions, has strengthened its position in the liquid cooling market with the acquisition of JetCool, a leading liquid cooling provider specializing in its patented direct-to-chip microconvective cooling® technology. Together, Flex and JetCool deliver end-to-end liquid cooling solutions for AI-driven computing environments at a global scale.

The demand for liquid cooling is surging, with analysts predicting the server cooling market will grow from $4.1 billion in 2024 to $10.6 billion by 2026, a 60.7% compound annual growth rate. High-power processors like Nvidia’s Blackwell GPUs are driving this shift, making heat, power, and scale bigger challenges for data center operators than ever. Flex and JetCool provide the solutions needed to meet these challenges.

JetCool’s microjet impingement technology sets it apart from traditional cold plates by using fluid jets to target processor hot spots, improving thermal performance by 24% over microchannel cold plates, as verified by third-party testing. JetCool’s scalable solutions range from cold plates cooling 3kW Superchips to high-capacity Coolant Distribution Units (CDUs) that support 300kW per rack and scale up to 2.1MW in row-level configurations. For companies transitioning to liquid cooling, JetCool’s self-contained systems require no plumbing or piping, making adoption seamless while delivering immediate efficiency gains.

As a Flex company, JetCool’s direct-to-chip liquid cooling is now manufactured and deployed at an unprecedented scale through Flex’s global footprint. This vertical integration removes traditional supply chain bottlenecks, reduces lead times from months to weeks, and enables rapid deployment anywhere in the world. With advanced liquid cooling solutions now available at scale, backed by global manufacturing and supply chain expertise, data centers can accelerate the adoption of liquid cooling and support the next generation of computing infrastructure.
