Standardizing FWS connections, OCP ACS Immersion Solutions - Thread type, delta T


Don Mitchell <Don.Mitchell@...>
 

The Advanced Cooling – Facilities (ACF) subproject of OpenComputeProject requests your input on standardizing connections to OCP ACS Immersion solutions.

 

Thread connection standardization:   General feedback to date has been:

-          FWS connection point under 2” = metric thread (DN 25 or DN 40)

-          FWS connection point > 2” would grooved coupling connection (or possibly a flanged connection)

Is it better let every vendor choose their thread connection of preference and let the local pipefitter figure it out?

 

Input request:   Do you see benefit to OCP global standard of the connection to the tank options.  (with adaptors used per customer and regional preference)

 

Delta T range standardization: 

  • Diversity in Delta T expectations adds complexity to planning. 

Input Request:  Can the range of delta T options be reduced for OCP solutions.

 

Will be sending a similar survey to ACS Cold Plate and ACS RDHX teams

 

Attached below are workstreams we are seeking to finalize into WPs by end of summer. 

Would value insights on alignment with ACS Immersion guidance

 

 

 

Kind Regards

Don,

My 2 cents:

I don't think OCP should adopt a global standard for metric threads at the facility level (ACF).  This will not facilitate adoption of liquid cooling in the US where many plumbing components are not widely available in metric.  Every vendor should choose their connections based on their target markets.  Some will have different standards for different markets.

Delta T should not be considered in isolation of supply temperature.  In my opinion it is more important to standardize on design supply temperature, but a combined  supply and delta T standard would be fine.
