Abstract

Embodiments of the present disclosure generally pertain to passive cooling systems and methods for electronics. An exemplary passive cooling system for electronics has a circuit package and dielectric liquid. The circuit package has a cover positioned over a circuit element coupled to a substrate. The cover is attached to the substrate and creates a water-tight seal around the circuit element. The circuit package further has a porous media. The dielectric liquid directly contacts the circuit element, and heat from the circuit element is transferred to the dielectric liquid. As the liquid reaches its boiling point, vapor from the liquid is passed through the porous media for further cooling.
