Abstract

An apparatus for cooling an electrical component is disclosed which comprises a sorber containing a sorbent; a condenser in fluid communication with the sorber; an evaporator in fluid communication with both the sorber and the condenser and connected in heat-exchange relation to the electrical component; wherein a sorbate which has been condensed in the condenser is evaporated in the evaporator, thereby absorbing heat from the electrical component, and then adsorbed onto the sorbent; an electromagnetic wave generator, a waveguide coupler for directing the electromagnetic waves to the sorbent; wherein the sorbate is desorbed from the sorbent by the electromagnetic waves and condensed in the condenser; and wherein the desorption of the sorbate from the sorbent is substantially isothermal.
