1. An adsorptive cooling system comprising:
a first highly adsorptive structure positioned to receive thermal energy from a thermal energy source, the first highly adsorptive structure comprising:
a first substrate, wherein the first substrate comprises a first plurality of microchannels configured to conduct thermal energy through an interior volume thereof; and
a first metal-organic framework (MOF) configured to adsorb and desorb a refrigerant under predetermined thermodynamic conditions, wherein the first MOF is adhered to an interior surface of the first plurality of microchannels;
a second highly adsorptive structure positioned to receive thermal energy from the thermal energy source, the second highly adsorptive structure comprising:
a second substrate, wherein the second substrate comprises a second plurality of microchannels configured to conduct thermal energy through an interior volume thereof; and
a second MOF configured to adsorb and desorb the refrigerant under predetermined thermodynamic conditions, wherein the second MOF is adhered to an interior surface of the second plurality of microchannels;
a cooling unit; and
a circulation system configured to circulate the refrigerant from at least one of the first highly adsorptive structure and the second highly adsorptive structure to the cooling unit to provide cooling from the thermal energy source and to return the refrigerant from the cooling unit to at least one of the first highly adsorptive structure and the second highly adsorptive structure,
wherein the first plurality of microchannels and/or the second plurality of microchannels are independently defined by:
grooves in a surface of the first substrate nearest the first MOF;
grooves in a surface of the second substrate nearest the second MOF;
surfaces of a first plurality of microcapillaries of the first substrate; and/or
surfaces of a second plurality of microcapillaries of the second substrate,
wherein the first plurality of microchannels and/or the second plurality of microchannels independently provide ingress and egress paths for the refrigerant, and
wherein the refrigerant is selected from the group consisting of: acid halides, alcohols, aldehydes, amines, chlorofluorocarbons, esters, ethers, fluorocarbons, perfluorocarbons, halocarbons, halogenated aldehydes, halogenated amines, halogenated hydrocarbons, halomethanes, hydrocarbons, hydrochlorofluorocarbons, hydrofluoroethers, hydrofluoroolefins, inorganic gases, ketones, nitrocarbon compounds, noble gases, organochlorine compounds, organofluorine compounds, organophosphorous compounds, organosilicon compounds, oxide gases, refrigerant blends and thiols.
