Abstract
Inserting new high power sensors and electronics on the E-8 aircraft will require highly effective cooling. Diamond substrates cooled by evaporative spray techniques can satisfy requirements for both extraordinary cooling effectiveness and tailorabilityto advanced radar systems. M. S. Sehmbey et al have demonstrated that evaporative spray cooled diamond surfaces can maintain components, with high heat fluxes, within a narrow isothermal temperature range. In this study, an isothermal temperature rangeof 120¿C-150¿C was maintained despite heat flux increases of 700 W/cm2 to a maximum (for the test conditions) of 1150W/cm2.These results established that combining diamond surfaces with evaporative spray cooling could generate the highly effective cooling needed by future airborne radar. Two developments have created the potential for producing such a system: (1) noveldiamond substrates fabricated from network polymers and (2) turn-key evaporative spray cooling systems currently being evaluated in DoD systems. A key feature, in both of these developments, is their tailorability to system configurations and coolingrequirements thus creating the opportunity to produce highly effective modular and scalable cooling systems. AMT, Inc. will lead a team to design diamond/evaporative spray cooling systems tailored for the E-8 aircraft and other airborne radomes andelectronics.Potential dual-use commercial applications include cooling of high power electronic switching systems, high power land based communications systems, satellites, and high-end computers and electronics.
