Rear door heat exchanger transition frame

Abstract

A transition frame system integrates a liquid cooling door with associated computer equipment racks. Dissimilar dimensions of equipment racks and cooling doors are accommodated by a transition frame. The frame has a top, bottom, first side, and a second side; each providing a rack face opposing a door face. The frame may be one piece. The rack face includes a means for mating/sealing with the rack and the door face includes a means for mating/sealing with a cooling door that may include replacement hinges and latches. The transition frame can be included as part of the rack or the door. Cooling of equipment in the rack is maintained through airflow through the cooling door.

AI Technical Summary

Benefits of technology

[0009]A system and method for integrating a liquid cooling door with associated computer equipment racks is disclosed. Transition frame embodiments include replacements for rack hinges and latches, overcoming the lack of standards in this area. The solution enables the purchase of inexpensive air-cooled racks initially, when relatively few components are installed. Then, as rack capacity is reached by adding components resulting in peak heat loads, the existing rack can be retrofitted with a rear door heat exchanger.

Problems solved by technology

This has reached the point where air conditioning systems are unable to cool computing facilities without supplemental liquid cooling.

For example, temperatures can climb 2 degrees Centigrade per minute following air conditioning failure, resulting in server shut down and 100 degree Fahrenheit temperatures in less than 15 minutes.

These are expensive and often exceed the needs and budget of start-ups and cost-sensitive operations.

Currently, the upgrade options available are limited and operationally prohibitive, often requiring shutting down equipment and replacing the racks housing it.

This rack replacement involving shutting down mission critical servers, removing the hardware, and reinstalling the equipment is a very expensive and labor intensive process.

No alternative may exist though, if expansion requires a new rack to accommodate a rear door heat exchanger.

While standardized rack sizes exist, variations prevent direct interchangeability of components such as doors.

This lack of interchangeability requires an extensive initial investment for a more advanced rack than may be required at start-up if rear door heat exchangers are anticipated.
