Publication number: 20200049435Abstract: A recirculating cooling system includes a coolant sampling line, a deterministic lateral displacement (DLD) microfluidic separation device, a monitoring device, and an alert generation device. The coolant sampling line is in fluid communication with a recirculating coolant line, and the DLD microfluidic separation device receives a coolant sample diverted into the coolant sampling loop from the recirculating coolant line via the coolant sampling line. The DLD microfluidic separation device includes a separation array for separating bacteria into an output channel according to a size threshold. The monitoring device monitors a characteristic property of the coolant sampling loop for comparison to a threshold for bacterial growth in the recirculating cooling system. The alert generation device generates an alert to remediate the bacterial growth in the recirculating cooling system responsive to the characteristic property of the coolant sampling loop satisfying the threshold.Type: ApplicationFiled: August 9, 2018Publication date: February 13, 2020Inventors: JASON T. WERTZ, JOSEPH KUCZYNSKI, BRADFORD O. BROOKS, DONALD W. PORTER, ALLAN C. VANDEVENTER

Publication number: 20180084676Abstract: A cooling system is provided which includes, for instance, a coolant circulation loop, one or more primary coolant pumps, and a fill and drain pump. The primary coolant pump(s) is coupled to facilitate circulating coolant through the coolant circulation loop, and the fill and drain pump facilitates selective filling of the cooling system with the coolant, or draining of the coolant from the cooling system. The fill and drain pump is integrated with the cooling system as a backup coolant pump to the primary coolant pump(s), and circulates the coolant through the coolant circulation loop responsive to an error in the primary coolant pump(s). The primary coolant pump(s) and fill and drain pumps may be different types of pumps, and the cooling system further includes a control system for automatically activating the fill and drain pump upon detection of an error in the primary coolant pump(s).Type: ApplicationFiled: November 28, 2017Publication date: March 22, 2018Inventors: David L.

Publication number: 20160215999Abstract: An apparatus is provided which includes a changeable cover assembly sized to cover, at least in part, an air outlet side of an electronics rack. The cover assembly, when positioned at the air outlet side of the rack, redirects and vents airflow egressing from the air outlet side. The cover assembly includes a frame and at least one vent cover. The frame has at least one opening through which air egressing from the electronics rack passes, and the vent cover(s) is coupled to the frame and overlies, at least in part, the opening(s) in the frame to facilitate redirecting and venting the air passing through the frame. The at least one vent cover is changeable to change a direction of the vented air. For instance, the vent cover(s) may be reversible, or otherwise adjustable or changeable, to change the direction of vented air egressing from the cover assembly.Type: ApplicationFiled: January 27, 2015Publication date: July 28, 2016Inventors: Seth E.

Publication number: 20120118534Abstract: An apparatus is provided for cooling an electronic system, which includes one or more electronic components across which air passing through the system flows. A cooling unit provides, via a coolant loop, system coolant to cool the electronic component(s), and to an air-to-liquid heat exchanger is coupled to the coolant loop downstream of the electronic component(s) to cool, in primary, liquid-cooling mode, air passing through the system. In primary, liquid-cooling mode, the cooling unit provides cooled system coolant to cool the electronic component(s), and provides system coolant to the air-to-liquid heat exchanger to cool at least a portion of air passing through the electronic system, and in a secondary, air-cooling mode, system coolant flows from cooling the electronic component(s) to the air-to-liquid heat exchanger for rejecting, via the system coolant, heat from the electronic component(s) to air passing across the air-to-liquid heat exchanger.Type: ApplicationFiled: November 16, 2010Publication date: May 17, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Gary F.
