Method and apparatus for cooling electrical components

摘要

An apparatus for cooling an electrical component is disclosed which comprises a sorber (12) containing a sorbent; a condenser (38) in fluid communication with the sorbet (12); an evaporator (42) in fluid communication with both the sorber (12) and the condenser (38) and connected in heat-exchange relation to the electrical component (208,210), wherein a sorbate which has been condensed in the condenser (38) is evaporated in the evaporator (42), thereby absorbing heat from the electrical component (208, 210), and then adsorbed onto the sorbent; an electromagnetic wave generator (16); a waveguide coupler (14) 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 (38); and wherein the desorption of the sorbate from the sorbent is substantially isothermal.
