Abstract
A self contained cooling system which is amenable to miniaturization so as to accommodate space and connectivity restrictions implicit in computer and other electronics apparatus while enhancing heat transfer. In use, the cooling systems of this invention use compression/expansion cycles of a refrigerant material to move thermal energy from one location to another. The compressor, condenser, and evaporator are all contained within a volume consistent with mounting directly on a semiconductor device such as a processor.
Claims14
An apparatus, comprising:
- a heat generating semiconductor chip;
- and
- a self contained refrigeration device mounted adjacent to and in heat transfer relation to said chip;
- wherein the refrigeration device includes:
- a compressor, and the compressor includes a housing, at least one trilobal impeller comprising a magneto ceramic body and mounted within said housing, and a plurality of electrically conductive coils interacting with said body;
- an evaporator in heat transfer relation to said chip;
- and
- a condenser;
- wherein said evaporator, compressor and condenser are configured to conduct a flow of a refrigerant medium there amongst.
An apparatus, comprising:
- a computer system;
- a heat generating semiconductor chip mounted in said computer system;
- and
- a self contained refrigeration device mounted in said computer system adjacent to and in heat transfer relation to said chip;
- wherein the self contained refrigeration device includes:
- a compressor, and the compressor includes a housing, at least one trilobal impeller comprising a magneto ceramic body and mounted within said housing, and a plurality of electrically conductive coils interacting with said body;
- an evaporator in heat transfer relation to said chip;
- and
- a condenser;
- wherein said evaporator, compressor and condenser are configured to conduct a flow of a refrigerant medium there amongst.
An apparatus, comprising:
- an evaporator element;
- a condenser element;
- and
- a compressor coupled with said evaporator and condenser for circulating a refrigerant material there amongst;
- said compressor having an housing, a magneto ceramic trilobal rotor mounted within said housing, and a plurality of electromagnetic coils disposed about said rotor and magnetically coupled thereto.
An apparatus, comprising:
- an evaporator element;
- a condenser element;
- and
- a compressor coupled with said evaporator and condenser for circulating a refrigerant material there amongst;
- said compressor having an housing, a plurality of trilobal rotors mounted within said housing, and mechanism coupling said plurality of rotors together for coordinated rotation so that vibrational forces otherwise generated by rotation thereof are counterbalanced.
