1. An evaporative thermal management device comprising:
a housing having a first case;
a second case positioned opposite the first case;
a plurality of supports extending from the first case to the second case and forming a cavity therebetween, the cavity having an operating pressure associated therewith;
at least one vent coupled to the housing and in fluid communication with the cavity; and
a working fluid disposed in the cavity;
wherein evaporation of the working fluid controls a temperature of a substrate when the cavity is at the operating pressure, and the evaporated working fluid forming in a space in the cavity between the working fluid and the substrate and is vented to an ambient environment surrounding the housing through the at least one vent.
