A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through a fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.

A data center cooling system is operated in a first mode, has an indoor portion wherein heat is absorbed from components in the data center by a heat transfer fluid, and has an outdoor heat exchanger portion and a geothermal heat exchanger portion. The first mode includes ambient air cooling of the heat transfer fluid in the outdoor heat exchanger portion and/or geothermal cooling of the heat transfer fluid in the geothermal heat exchanger portion. Based on an appropriate metric, a determination is made that a switch should be made from the first mode to a second, different, mode; and, responsive thereto, the data center cooling system is switched to the second mode. The second mode includes at least another of ambient air cooling of the heat transfer fluid in the outdoor heat exchanger portion and geothermal cooling of the heat transfer fluid in the geothermal heat exchanger portion.

An information handling system includes a front door having a first frame, a main portion, and a rear portion. The main portion includes a second frame, a component node having multiple components, and a first channel. The rear portion includes a third frame, a cooling coil, a cooling fan, and a second channel. The information handling system is airtight when the first frame is in physical communication with a first end of the second frame and the third frame is in physical communication with a second end of the second frame. An airflow circulates within the information handling system to cool the components in the component node. The airflow circulates from the cooling coil to the cooling fan, through the second channel, through the first channel, through the component node, and back through the cooling coil.

A cable adapter for a server chassis is disclosed. The cable adapter comprises an adapter body having a first surface with a key slot. The key slot is configured to receive a key rib on a busbar clip of the server chassis. A pair of latches are pivotably attached to opposite sides of the adapter body. Each latch has a latch arm that extends across an open end of the adapter body when in a closed position. The latch arms are configured to engage one or more latching ribs on the blades of the busbar clip such as by hooking around the latching ribs. A pair of connectors inside the adapter body configured to engage blades of the busbar clip.
