Investigations of supersonic micro-ejector for cooling system of electronic components.

Summary

Innovative approach for electronics cooling was proposed, i.e. heat generated by a part of electronic equipment, e.g. CPU, is absorbed by heat driven micro-ejector refrigeration system that can provide cooling of other electronic components, e.g. GPU. It was demonstrated the procedure of design, fabrication, and experimentation on the supersonic micro-ejectors for the case of isobutane as a working fluid for such system. For the discussed micro-ejector entrainment ratio obtained was app. 0.20 under conditions of the motive heat source temperature app. 60 °C and evaporation temperature app. 22 °C. For reported tests conditions the boundary temperature of the on-design operation condition was between 21 – 25 °C. CFD technique used for numerical predictions of the ejector performance fits to experimental measured values with acceptable accuracy.
