Adsorption cooling system using metal organic frameworks

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, and
• a first metal-organic framework (MOF) coupled to the first substrate and adapted for adsorbing and desorbing a refrigerant under predetermined thermodynamic conditions;
• a second highly adsorptive structure positioned to receive thermal energy from the thermal energy source, the second highly adsorptive structure comprising:
• a second substrate, and
• a second MOF coupled to the second substrate and adapted for adsorbing and desorbing the refrigerant under the predetermined thermodynamic conditions;
• a cooling unit;
• and
• a circulation system adapted for circulating the refrigerant from the first highly adsorptive structure and/or 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 the first highly adsorptive structure and/or the second highly adsorptive structure,
• wherein the first and/or the second substrate comprises a plurality of microchannels,
• wherein the microchannels are defined by grooves in a surface of the substrate nearest the MOF and/or surfaces of a plurality of microcapillaries of the substrate, and
• wherein the microchannels provide ingress and egress paths for the refrigerant.
