Abstract
A liquid-cooled roll-formed busbar assembly comprises a sheet of copper or similarly conductive metal roll-formed into at least one arcuate region. One or more cooling pipes of a fluid network (e.g., a coolant supply pipe and a coolant return pipe) circulate a cooling fluid through the busbar such that the arcuate region/s conform to a portion of the external circumference of the cooling pipe/s. A thermal interface is disposed between the cooling pipes and the liquid-cooled roll-formed busbar, such that the circulating fluid absorbs heat from the busbar via the thermal interface and transfers the absorbed heat to a primary fluid network.
Claims18
A busbar assembly, comprising:
- at least one busbar attached to a rack, the busbar configured to carry a current load between a power source and at least one information technology (IT) device disposed within the rack, the at least one busbar comprising a metallic sheet roll formed into at least one arcuate region;
- at least one cooling pipe defining a portion of a fluid network configured for circulating a fluid refrigerant through at least one of the rack or the at least one IT device, wherein the at least one arcuate region of the busbar at least partially conforms to an external circumference of the at least one cooling pipe;
- and
- a thermal interface between the at least one cooling pipe and the at least one arcuate region, wherein the thermal interface comprises at least one thermally conductive material.
A method for providing operating power, the method comprising:
- providing at least one information technology (IT) device disposed within a rack;
- providing a power source configured for supplying operating current to the at least one IT device;
- providing a fluid network configured for thermal management of the at least one IT device, wherein the fluid network comprises at least one cooling pipe configured for circulating a fluid refrigerant through one or more of the rack or the at least one IT device;
- providing at least one busbar attached to the rack, wherein the busbar is configured to carry a current load between the power source and the at least one IT device, wherein the at least one busbar comprises a metallic sheet roll formed into at least one arcuate region, and wherein the at least one arcuate region at least partially conforms to an external circumference of the at least one cooling pipe;
- and
- providing a thermal interface between the at least one arcuate region and the at least one cooling pipe, wherein the thermal interface comprises at least one thermally conductive material.
