Title: Intelligent threshold leak remediation of datacenter cooling systems
Inventor: ALI HEYDARI
IPC: H05K7/20
Filed: 2021-08-27
Abstract: A remediation system for leaks in a data centre liquid cooling system having a coolant fluid flow controller 410 and a power controller 418 of a power distribution system for the computing components in racks 402. A learning subsystem, such as a trained neural network, can determine that a leak has occurred at a threshold level where a computing component is still functioning normally and at nominal operating temperature. The learning system receives operating parameters such as pressure, flow rate and temperature of the coolant at various locations, temperatures of computing components and temperature and humidity at various areas of the data centre. The parameters may be compared with various threshold values and moving ranges. If such a threshold leak is found, it is signalled to both the power and coolant controllers to effect a change in power state to reduce reliance on the coolant and a change of flow of the coolant. The cooling system can comprise multiple loops (fig 1). The flow controllers (222) may be within a server module (fig 2) and or they (32) may be at the rack-level (fig 3). Power controllers (322) may be part of a power distribution system (308, 310) at the rack level (fig 3). The control system may be distributed.
