Abstract
Disclosed are cooling systems and methods for detecting coolant leakage. Processors of servers are attached to cold plates. An internal liquid coolant is contained in a coolant reservoir and is circulated through the cold plates via a coolant distribution manifold. Coolant leakage is detected based at least on a level of the internal liquid coolant in a tapered chamber of the coolant distribution manifold.
Claims15
A cooling system for a plurality of servers, the cooling system comprising:
- a plurality of cold plates that are attached to corresponding processors of the plurality of servers;
- a coolant reservoir that contains an internal liquid coolant;
- and
- a coolant distribution manifold through which the internal liquid flows from the coolant reservoir to the plurality of cold plates, the coolant distribution manifold having a tapered chamber, a first liquid level sensor that monitors a level of the internal liquid coolant in the tapered chamber, and an air-relief valve that is connected to the tapered chamber.

A method of detecting coolant leakage, the method comprising:
- attaching cold plates to processors of a plurality of servers;
- flowing an internal liquid coolant from a coolant reservoir through the cold plates via a coolant distribution manifold;
- monitoring a level of the internal liquid coolant in a tapered chamber of the coolant distribution manifold;
- detecting leakage of the internal liquid coolant responsive to the level of the internal liquid coolant in the tapered chamber triggering one or more liquid level sensors;
- and
- initiating an intervention to protect the plurality of servers responsive to detecting the leakage of the internal liquid coolant.
