History

Space Station Freedom

Space Station Freedom

Mikros Manufacturing, Inc was founded by Dr. Javier Valenzuela in 1991 to commercialize micro-EDM technology developed under an SBIR project for NASA Johnson Space Center. The project involved the development of a droplet-impingement evaporator for thermal management on board the Space Station Freedom. Mikros has continued to develop this micro-EDM technology and is presently the world leader in the fabrication of stainless steel micro-nozzles for industrial ink-jet marking systems.

 

The interface heat exchanger rejecting heat from the Crew Habitat required coupling the ammonia droplet-impingement evaporator to a single phase water heat exchanger.   Dr. Valenzuela developed the Normal Flow microchannel heat exchanger (NFHX) to achieve comparable heat transfer rate to that of the ammonia evaporator.   Mikros has continued to advance this technology and our patented Normal Flow heat transfer matrix is capable of removing over 1000 W/cm ² with an approach temperature difference of only 20 ° C and a pressure drop of 20 kPa (3 psi).
