Two-Phase Flow in High-Heat-Flux Micro-Channel Heat Sink for Refrigeration Cooling Applications. Part 2: Low Temperature Hybrid Micro-Channel/Micro-Jet Impingement Cooling

Abstract

This report examines the pressure drop and heat transfer characteristics of two-phase micro-channel heat sinks. New models and correlations are proposed for both saturated and subcooled boiling conditions. These tools are shown to provide accurate predictions of pressure drop, two-phase heat transfer coefficient and critical heat flux. Also discussed in this report is a new hybrid cooling system that combines the cooling attributes of micro-channel flow and jet impingement. It is shown this system is very effective at meeting the cooling demands of high-flux defense electronics, including the ability to dissipate in excess of 1000 W/sq cm. Detailed predictive tools are provided to tackle the design of a hybrid cooling module.
