Appl. No.:

17/128731

Inventors:

- Cambridge MA, US
James Paul Smith - Chelmsford MA, US
Eric A. Browne - Westford MA, US

International Classification:

H01L 23/473
F28D 1/02
F28F 3/12
F28F 13/06
H01L 21/48
H05K 7/20

Abstract:

The present invention generally relates to a microjet array for use as a thermal management system for a heat generating device, such as an RF device. The microjet array is formed in a jet plate, which is attached directly to the substrate containing the heat generating device. Additional enhancing features are used to further improve the heat transfer coefficient above that inherently achieved by the array. Some of these enhancements may also have other functions, such as adding mechanical structure, electrical connectivity or pathways for waveguides. This technology enables higher duty cycles, higher power levels, increased component lifetime, and/or improved SWaP for RF devices operating in airborne, naval (surface and undersea), ground, and space environments. This technology serves as a replacement for existing RF device thermal management solutions, such as high-SWaP finned heat sinks and cold plates.

- Cambridge MA, US
Eric A. Browne - Westford MA, US

International Classification:

H01L 23/473

Abstract:

The present invention generally relates to a modular microjet cooler. The modular microjet cooler may be attached to a packaged heat generating device that is mounted on a printed circuit board. The modular microjet cooler has an inlet allowing supply fluid to be directed through microjet nozzles toward an impingement surface on the packaged device. The modular microjet cooler also has one or more outlets that allow exhaust fluid to be removed. The modular microjet cooler is attached to the device after it has been packaged. Further, the modular microjet cooler may be attached to the packaged device either before or after it is mounted to the printed circuit board.

International Classification:

H05K 1/02
H05K 7/20
H01L 23/473

Abstract:

The present invention generally relates to an array backframe with integral manifolding for high performance fluid cooling of devices. The integral manifolding of the array backframe is designed to perform three functions. First, the array backframe parallelizes the fluid paths to provide uniform, cool supply fluid to every device in the array. Second, the array backframe minimizes the parasitic heat losses between supply and exhaust by use of an isolation cavity. Third, the array backframe collapses hundreds of fluid lines into a single internal manifold to enhance modularity while also serving as a structural support member.
