Leak auto detection for a rack liquid cooling system

A computer program product for testing a closed cooling loop for leaks, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being readable and/or executable to:

• cause, by a processor, air to be pumped into the closed cooling loop;
• identify, by the processor, an initial internal temperature value and an initial internal pressure value of the closed cooling loop;
• in response to a predetermined amount of time passing since the air was pumped into the closed cooling loop, identify, by the processor, an updated internal temperature value and an updated internal pressure value of the closed cooling loop;
• use, by the processor, (i) the initial internal temperature value, (ii) the initial internal pressure value (iii) the updated internal temperature value, and (iv) the updated internal pressure value, to determine if the closed cooling loop has a leak;
• in response to determining that the closed cooling loop has a leak, issue, by the processor, a warning;
• wherein using (i) the initial internal temperature value, (ii) the initial internal pressure value, (iii) the updated internal temperature value, and (iv) the updated internal pressure value, to determine if the closed cooling loop has a leak includes:
• determining whether the initial internal temperature value is about equal to the updated internal temperature value;
• in response to determining that the initial internal temperature value is about equal to the updated internal temperature value, determining whether the initial internal pressure value is about equal to the updated internal pressure value;
• and
• in response to determining that the initial internal pressure value is not about equal to the updated internal pressure value, identifying that the closed cooling loop has a leak.

A compute system comprising:

• a coolant distribution unit;
• a central controller;
• and
• logic integrated with and/or executable by the central controller, the logic being configured to:
• cause, by the central controller, air to be pumped into a cooling loop;
• identify, by the central controller, an initial internal temperature value and an initial internal pressure value of the cooling loop;
• in response to a predetermined amount of time passing since the air was pumped into the cooling loop:
• identify, by the central controller, an updated internal temperature value and an updated internal pressure value of the cooling loop;
• use, by the central controller, (i) the initial internal temperature value, (ii) the initial internal pressure value, (iii) the updated internal temperature value, and (iv) the updated internal pressure value, to determine if the cooling loop has a leak;
• in response to determining that the cooling loop has a leak, issue, by the central controller, a warning;
• wherein using (i) the initial internal temperature value, (ii) the initial internal pressure value, (iii) the updated internal temperature value, and (iv) the updated internal pressure value, to determine if the cooling loop has a leak includes:
• determining whether the initial internal temperature value is about equal to the updated internal temperature value;
• in response to determining that the initial internal temperature value is about equal to the updated internal temperature value, determining whether the initial internal pressure value is about equal to the updated internal pressure value;
• and
• in response to determining that the initial internal pressure value is not about equal to the updated internal pressure value, identifying that the cooling loop has a leak.
