A coupling that includes a female coupling member having at least one electrically conductive ring on an inner mating surface; a male coupling member having at least one electrically conductive ring on an outer mating surface, the outer mating surface sized to fit within the inner mating surface of the female coupling member; and wherein when the male coupling member is inserted into the female coupling member, alignment of the at least one electrically conductive ring of the female coupling member with the at least one electrically conductive ring of the male coupling member indicates whether the female coupling member and the male coupling member are fully engaged.

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.

Monitoring a recirculating cooling system for bacterial growth

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).

An apparatus for a switchable filter assembly includes a first conduit coupled to a second and a third conduit, where a liquid has the ability to flow through the first conduit to the second conduit and the third conduit, and where the second conduit and the third conduit are arranged in parallel. A first assembly is capable of sliding inside the first conduit, such that a position of the first assembly determines an amount of liquid flowing to the third conduit. The first assembly includes a compressible member coupled to a first structure, where the first structure prevents the liquid from passing through the first conduit to the third conduit. An amount of compression of the compressible member coupled to the first structure is dependent on a pressure of the liquid flowing from the first conduit to the second conduit.

Autonomous filtration switch

A cooling assembly is provided which includes: one or more coolant-cooled heat sinks configured to couple to one or more electronic components to be cooled; one or more flexible coolant conduits; and one or more pivotable coolant manifolds. The flexible coolant conduit(s) couples in fluid communication the pivotable coolant manifold(s) and the coolant-cooled heat sink(s), and accommodates pivoting of the pivotable coolant manifold(s), while maintaining the coolant-cooled heat sink(s) in fluid communication with the pivotable coolant manifold(s). In one or more embodiments, the pivotable coolant manifold(s) pivots between a first position laterally offset from one or more of the coolant-cooled heat sink(s), and a second position above the one or more coolant-cooled heat sinks. First and second pivot arms may be provided at opposite ends of the pivotable coolant manifold(s) to facilitate pivotable movement of the manifold(s) between the first position and the second position.

Cooling apparatuses, cooled electronic modules, and methods of fabrication are provided which facilitate heat transfer from one or more electronic components to a liquid coolant in an operational mode, and drainage of coolant therefrom in a transport mode. The cooling apparatus includes a liquid-cooled heat sink configured to horizontally couple along a main heat transfer surface to the electronic component(s). The heat sink includes a thermally conductive structure with a coolant-carrying compartment through which coolant flows, and a coolant inlet tube and a coolant outlet tube affixed to the thermally conductive structure and in fluid communication with the coolant-carrying compartment to facilitate coolant flow through the compartment. The coolant-carrying compartment has a base surface, and the coolant outlet tube extends into the coolant-carrying compartment towards the base surface to facilitate withdrawal of the liquid coolant from the compartment in the transport mode of the cooling apparatus.

Liquid-cooled heat sink configured to facilitate drainage

Apparatuses and methods are provided for preventing removal of an air-moving assembly from a chassis when in operating state. The apparatus includes an interlock assembly having a slide element and one or more interlock elements. The slide element is slideably coupled to the air-moving assembly and resides in a first position when the air-moving assembly is in the operating state, and is slidable to a second position when the air-moving assembly is in a quiesced state. The slide element prevents removal of the air-moving assembly from the chassis in the first position, and allows removal of the air-moving assembly from the chassis in the second position. The interlock element(s) is associated with the slide element and prevents sliding of the slide element from the first position to the second position when the air-moving assembly is in the operating state.

Flexible coolant manifold-heat sink assembly

An electronics rack with a cooling apparatus and a liquid-coolant-driven, electricity-generating system. The generating system includes a housing coupled in fluid communication with a fluid transport pipe of the cooling apparatus, an impeller disposed within the housing and positioned to turn with flow of fluid across the impeller, one or more magnetic structures disposed to turn with turning of the impeller, and an electrical circuit. Electricity is generated for the electrical circuit with turning of the one or more magnetic structures, and is supplied to an electrical load disposed within or associated with the electronics rack.
