1. An apparatus for cooling an electrical component which comprises:

  • at least one sorber having a housing forming an enclosure,a sorbent located within the enclosurethe sorber including at least one port through which a sorbate may be communicated to the sorbent;

    wherein the sorbate is adsorbed by the sorbent to form a sorbate/sorbent compound;

    an electromagnetic wave generator coupled to the sorber;

    wherein electromagnetic waves transmitted by the electromagnetic wave generator are propagated through the enclosure to desorb the sorbate from the sorbate/sorbent compound;

    wherein the sorbate/sorbent compound is not heated by the electromagnetic waves to a degree sufficient to thermally desorb the sorbate from the sorbate/sorbent compound;

    a condenser connected downstream of the sorber in communication with the enclosure;

    an evaporator connected between the condenser and the port and coupled in heat-exchange relation to the electrical component, anda controllable valve interposed between the condenser and the evaporator;

    wherein sorbate which is desorbed in the sorber is condensed in the condenser and then controllably released into the evaporator to create a cooling effect and thereby cool the electrical component, after which the sorbate is drawn back into the sorber.
