About JetCool
We design, engineer and manufacture end-to-end liquid cooling solutions for compute-intensive applications.
Our mission is to engineer next‑generation liquid cooling solutions that enable a more sustainable world. As data centers continue to grow in scale and intensity, JetCool addresses their immense energy and water demands by designing innovative cooling technologies that reduce consumption and carbon impact. Through continuous innovation, we empower high‑performance computing while helping our customers operate more efficiently, profitably, and sustainably.
JetCool’s liquid cooling technology wasn’t born in a data center—it was born in the sky. Originally developed at MIT Lincoln Laboratory for high‑power airborne electronics, our patented microjet impingement technology was engineered to perform in extreme conditions where vibration, gravity, and orientation don’t cooperate. Spun out in 2019, JetCool brought this rugged, orientation‑agnostic cooling to the world’s most demanding processors.

JetCool, a Flex company, designs, engineers, and manufactures high‑performance liquid cooling solutions that enable today’s most demanding compute‑intensive environments, from cloud and enterprise to colocation, semiconductors, and OEMs.
JetCool engineers a comprehensive range of standard and custom liquid cooling technologies, including liquid cold plates, coolant distribution units, AIO liquid‑assisted systems, manifolds, and universal quick disconnects. These technologies are combined into vertically integrated, liquid‑cooled rack solutions delivered as complete systems.
JetCool has a patented microconvective cooling® technology that uses an array of jets to precisely target processor hot spots. In addition, the company develops alternative cold plate architectures, including finned, skived, and pin‑based microchannel designs that deliver uniform, parallel flow across the processor lid. Cold plate configurations are selected and optimized based on application‑specific requirements such as performance targets, sustainability considerations, lead times, and budget.
Founded in 2019 as a spin‑out from MIT, JetCool has grown its liquid cooling technologies across the data center market. Today, the company is recognized for its efficiency and sustainability and is trusted by leading OEMs, semiconductor companies, and hyperscale data center operators.
Following its acquisition by Flex in 2024, JetCool is integrated into Flex’s data center business, enhancing the company’s end‑to‑end liquid cooling capabilities.
