Nvidia patents smart valve system to balance datacenter cooling
Nvidia describes a cooling setup for datacenters that uses a main controller to manage the flow of liquid coolant to multiple smaller sections. The system adjusts the main flow rate based on feedback from individual controllers in each section to keep temperatures stable.
In the filing’s own words
Systems and methods for a datacenter cooling system are disclosed. In at least one embodiment, a secondary cooling loop interfaces with a primary cooling loop and includes at least one processor that is adapted with a first proportional-integral-derivative (PID) controller to control a first flow controller, which can cause a flow rate for a secondary coolant from a coolant distribution unit (CDU) to a plurality of second flow controllers, and where the plurality of second flow controllers are associated with a plurality of second PID controllers and the flow rate is based in part of on feedback from the plurality of second PID controllers.
What exactly they claim (claim 1)
1. A datacenter cooling system, comprising: a secondary cooling loop that interfaces with a primary cooling loop and that comprises at least one processor adapted with a first proportional-integral-derivative (PID) controller to control a first flow controller, the first flow controller to cause a flow rate for a secondary coolant from a coolant distribution unit (CDU) to a plurality of second flow controllers, the plurality of second flow controllers associated with a plurality of second PID controllers, the flow rate based in part of on feedback from the plurality of second PID controllers to the first PID controller.
