Micro-Jet Arrays for Cooling of Electronic Equipment
ASME 3rd International Conference on Microchannels and Minichannels, Part B cont’d, 2005A high heat flux cooling system using an array of micro-jets is presented. The Micro-Jet Cooling Array (MJCA) is based on an array of small diameter micro-jets, with jet diameters as low as 300 microns. The return flow in MJCA is arranged so that the effect of neighboring jets is essentially eliminated and the high heat fluxes achievable in a single ...
