Cooling apparatus for electronic and computer components

Apparatus for cooling components or subassemblies of equipment at one or more locations comprising:

• one or more first and one or more second reactors, remote from said equipment, each containing a complex compound of a polar refrigerant and a metal halide, sulphate, nitrite, nitrate, sulfide, oxalate, chlorate salt, or double metal chloride salt, or mixtures, or eutectic, peritectic or stoichiometric mixtures of said salts, of a metal selected from the group consisting of an alkali and alkaline earth metal, transition metal, aluminum, zinc, copper, cadmium and tin, a first heater in said first reactor and a second heater in said second reactor for heating the complex compound therein, respectively,
• a condenser, remote from said equipment, for converting gaseous refrigerant to a liquid phase, and means for cooling said condenser with ambient air,
• a plurality of evaporators, each in independent heat exchange communication with one or more of said components or subassemblies within said equipment,
• valve means cooperating with first conduit means for alternately directing polar refrigerant from said first and said second reactors, respectively, to said condenser, and
• a plurality of second conduits for directing polar refrigerant from said condenser to said evaporators and a plurality of third conduits for directing polar refrigerant from said evaporators to said first and said second reactors wherein each of said evaporators is located between a different pair of said second conduits and said third conduits, respectively, said second conduits for directing refrigerant from said condenser to said evaporators, and said third conduits for directing said refrigerant from said evaporators to said reactors.

• valve means cooperating with first conduit means for alternately directing polar refrigerant from said first and said second reactors, respectively, to said condenser,
• a plurality of successive evaporators in series, each in independent and separate heat exchange communication with a different one or more of said components or subassemblies, and
• second conduit means for directing gaseous refrigerant from said condenser to a first one of said plurality of evaporators, third conduit means for directing gaseous refrigerant from a last evaporator of said plurality of evaporators to said reactors, and fourth conduit means for directing gaseous refrigerant from said first one of said evaporators sequentially and serially to each of aid successive evaporators and to said last evaporator of said plurality of evaporators, whereby said refrigerant sequentially and serially cools said components or subassemblies in said plurality of successive evaporators, respectively.
