Cooling System, Cooled Computer System and Computer Facility

摘要

A cooling system for the electronic components of a computer rack, including a primary circuit of primary liquid; a primary exchanger intended to transfer heat from first electronic components to the primary liquid; a secondary circuit of refrigerant fluid; a primary-secondary exchanger; a tertiary circuit of tertiary liquid; a secondary-tertiary exchanger; and a tertiary-thermal source exchanger. The cooling system also includes a tertiary-secondary exchanger; and an air-tertiary exchanger intended to transfer, to the tertiary liquid, heat from the air of the computer rack heated by second electronic components, the air-tertiary exchanger being arranged, in the tertiary circuit, downstream of the tertiary-secondary exchanger and upstream of the secondary-tertiary exchanger.

主权项

1. A cooling system for electronic components of a computer rack, comprising:
a closed circuit, referred to as a primary circuit, of liquid, referred to as primary liquid; a primary exchanger which transfers heat from a plurality of first electronic components to the primary liquid, the primary exchanger further comprising a heat-conducting part provided in contact with the primary liquid and adapted to be pressed against said plurality of first electronic components; a closed circuit, referred to as secondary circuit, of refrigerant fluid; a primary-secondary exchanger which transfers heat from the primary liquid to the refrigerant fluid; a closed circuit, referred to as tertiary circuit, of liquid, referred to as tertiary liquid; a secondary-tertiary exchanger which transfers heat from the refrigerant fluid to the tertiary liquid, such that the refrigerant fluid changes state at least partially; and a tertiary-thermal source exchanger which transfers heat from the tertiary liquid to a thermal source,wherein the tertiary-thermal source exchanger further comprises
a tertiary-secondary exchanger which transfers heat from the tertiary liquid to the refrigerant fluid; and an air-tertiary exchanger which transfers, to the tertiary liquid, heat from the air of the computer rack heated by second electronic components, said air-tertiary exchanger being arranged, in the tertiary circuit, downstream of the tertiary-secondary exchanger and upstream of the secondary-tertiary exchanger.
