Abstract
An example device in accordance with an aspect of the present disclosure includes a sensor, a controller, and an injector. The sensor is to provide sensor output regarding fluid chemistry of a fluid of a cooling system. The controller is to identify attributes of the fluid. The injector is to inject at least one additive into the fluid to bring at least one attribute into a threshold range.
Claims20
A device comprising:
- a sensor to provide sensor output regarding fluid chemistry of a fluid of a cooling system, the cooling system comprising a liquid cooling loop disposed in a computer system;
- an injector to inject at least one additive into the fluid, the injector including a plurality of reservoirs to store a plurality of additives wherein at least one of the plurality of reservoirs is replenishable with the at least one additive without stopping the computer system;
- a controller to:
- identify based on the sensor output, a plurality of attributes corresponding to at least one of pH, biocide, and corrosion inhibitor levels of the fluid;
- identify that at least one attribute is outside of a threshold range;
- direct the injector to inject the at least one additive corresponding to the at least one attribute, to bring the at least one attribute into the threshold range;
- and
- send an order to a remote location for at least one replacement additive when the at least one additive reaches an action threshold fill level.
5 more elements
A system comprising:
- a coolant distribution unit (CDU) to distribute a fluid of a cooling system and control a flow of the fluid to a computing rack;
- a sensor coupled to the CDU to provide sensor output;
- a controller to identify in real-time, based on the sensor output, a plurality of attributes of fluid chemistry of the fluid;
- an injector to inject in real-time at least one additive into the fluid, wherein the injector includes a plurality of reservoirs to store a plurality of additives, and a corresponding plurality of gauges to identify fill levels of the plurality of reservoirs;
- and
- the controller to identify, based on the sensor output, that at least one attribute is outside of a threshold range, direct the injector to inject a corresponding at least one additive to bring the at least one attribute into the threshold range, wherein the controller is to identify that a given reservoir fill level has reached an action threshold, and provide a refill indication corresponding to the given reservoir, and send an order to a remote location for at least one replacement additive when the at least one additive reaches an action threshold fill level.

A method, comprising:
- obtaining, via a sensor, sensor output indicative of fluid chemistry of a fluid of a cooling system;
- identifying, by a controller according to the sensor output, a plurality of attributes corresponding to levels of a pH, a biocide, and a corrosion inhibitor in the fluid;
- identifying that at least one attribute is outside of a threshold range;
- and
- injecting, by an injector as directed by the controller, at least one additive into the fluid to bring the corresponding at least one attribute into the threshold range, wherein the at least one additive is provided from a plurality of reservoirs to store a plurality of additives and;
- provisioning by automatically ordering from a remote location at least one replacement additive when the at least one additive reaches an action threshold fill level.
