Abstract

A compact, lightweight, and efficient evaporative spray cooling system is provided for removing high heat fluxes from surfaces of devices such as micro-electronic chips, metal, mirrors, and lasers. The system uses expanding metastable two-phase flow and a method of controlling the spray for optimum heat flux removal. Control includes spray atomization, fluid-phase, mass flow, and spray temperature.
