Cooling system for computer electronics
View Patent ↗A cooling system is provided for supplying a coolant flow to a cold plate associated with a processing chip of an electronic device to cool the processing chip. The system includes an electric motor driven fan; a radiator; an accumulator tank connected to the radiator for the transfer of coolant between the accumulator and the radiator; an electric driven pump connected to at least one of the radiator, the accumulator, and the cold plate to provide the coolant flow through the radiator and the cold plate; and a fan shroud adapted to direct the airflow provided by the fan. The fan, the radiator, the accumulator tank, and the pump are mounted on the shroud to be carried thereby, and the pump is located on an exterior side of the of the fan shroud and outside of the radiator and the accumulator tank.
1. A cooling system for supplying a coolant flow to at least one cold plate associated with a processing chip of an electronic device to cool the processing chip, the system comprising:
an electric motor driven fan;
an air-cooled radiator to transfer heat from a coolant flow to an air flow provided by the fan;
an accumulator tank connected to the radiator for the transfer of the coolant between the accumulator and the radiator;
an electric driven pump connected to at least one of the radiator, the accumulator, and the at least one cold plate to provide the coolant flow through the radiator and the at least one cold plate; and
a fan shroud adapted to direct the airflow provided by the fan, wherein the fan, the radiator, the accumulator tank, and the pump are mounted on the shroud to be carried thereby, and the pump is located on an exterior side of the of the fan shroud and outside of the radiator and the accumulator tank.
2. The system of claim 1 wherein the fan shroud surrounds both the radiator and the fan.
3. The system of claim 1 further comprising a conduit connecting the pump to the radiator.
4. The system of claim 1 wherein the fan is part of a pancake type electric fan unit.
5. The system of claim 1 wherein the radiator includes flat tubes extending between the accumulator tank and a manifold to direct the coolant flow therebetween.
6. The system of claim 5 wherein the radiator further includes serpentine fins extending between adjacent tubes.
7. An electronic device comprising;
at least one processing chip; and
a cooling system for cooling the processing chip, the cooling system comprising
at least one cold plate mounted adjacent the at least one processing chip to transfer heat from the processing chip to a coolant flow passing through the at least one cold plate;
an electric motor driven fan;
an air-cooled radiator to transfer heat from the coolant flow to an air flow provided by the fan;
an accumulator tank connected to the radiator for the transfer of the coolant between the accumulator and the radiator;
an electric driven pump connected to at least one of the radiator, the accumulator, and the at least one cold plate to provide the coolant flow through the radiator and the at least one cold plate; and
a fan shroud adapted to direct the airflow provided by the fan, wherein the fan, the radiator, the accumulator tank, and the pump are mounted on the shroud, the shroud is mounted to the electronic device, and the pump is located on an exterior side of the of the fan shroud and outside of the radiator and the accumulator tank.
8. The electronic device of claim 7 wherein the fan shroud surrounds both the radiator and the fan.
9. The electronic device of claim 7 wherein the cooling system further comprises a conduit connecting the pump to the radiator.
10. The electronic device of claim 7 wherein the fan is part of a pancake type electric fan unit.
11. The electronic device of claim 7 wherein the radiator comprises flat tubes extending between the accumulator tank and a manifold to direct the coolant flow therebetween.
12. The electronic device of claim 11 wherein the radiator further comprises serpentine fins extending between adjacent tubes.
