Claim of US Patent No. 10,015,911

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;
a tertiary-thermal source exchanger which transfers heat from the tertiary liquid to a thermal source,
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 air 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,
wherein the secondary circuit comprises first and second loops both passing in the secondary-tertiary exchanger and having a common portion, wherein the first loop bypasses the tertiary-secondary exchanger and the second loop bypasses the primary-secondary exchanger, and wherein the primary-secondary exchanger is arranged in the first loop and the tertiary-secondary exchanger is arranged in the second loop.
