Nvidia patents data center cooling that uses cryogenic fluids
Nvidia describes a cooling system for data centers that combines a standard liquid coolant with a cryogenic fluid to manage heat. The system uses a control unit to activate the cryogenic cooler only when hardware generates high heat or power usage, while the standard cooler handles normal loads.
In the filing’s own words
A coolant distribution unit (CDU) and a cryogenic cooling unit (CCU) may cool heat-generating components in hardware. The CDU and CCU may be selectively activated to cool the heat-generating components during high-performance tasks. The CCU may be activated in response to a high amount of heat generation, GPU utilization, or power consumption. The CCU and CDU may have separate cooling loops which cover nonoverlapping portions of hardware.
What exactly they claim (claim 1)
1. A cooling system in a data center, comprising: a coolant distribution unit (CDU) operably connected to a hardware component via a first connecting element, the CDU to transfer heat from the hardware component via fluid-based coolant; a cryogenic cooling unit (CCU) operably connected to the hardware component via a second connecting element, the CCU to transfer heat from the hardware component via cryogenic fluid; and a control system to activate the CDU and the CCU either simultaneously or independently of each other.
