JetCool

Company brief

What JetCool does

JetCool supplies direct-to-chip cooling modules built around microconvective cooling: arrays of small liquid jets target hot regions on a processor instead of relying only on flow through conventional plate channels. Its products range from sealed cold plates to approaches that bring fluid closer to the package or die, and the company also supplies manifold hardware for rack integration. This makes JetCool primarily a server-side thermal technology provider, not the vendor for the entire facility plant.

The approach is aimed at high heat flux and warm-water operation, where concentrating flow at the hot spot may lower thermal resistance and allow the chip to run without throttling. JetCool reports support for devices from 150 watts to more than 2,000 watts and cites coolant temperatures above 50 degrees Celsius in high-performance-computing use. Those figures come from the company and depend on a particular device, interface, flow, and test setup.

A buyer must verify a production cold plate for the exact processor package, server qualification and warranty, material and coolant compatibility, pressure drop, pump capacity, quick connections, leak testing, manifold balancing, and how memory, networking, and power components are cooled. Facility teams also need to assign responsibility for the coolant distribution unit and final heat rejection. JetCool's performance and savings statements are company-reported; the public profile does not establish broad server-vendor coverage, installed fleet size, pricing, or independent long-duration reliability.
