摘要： Compliant conduction rail assembly and method are provided for facilitating cooling of an electronics structure. The rail assembly includes a first thermally conductive rail mounted to a surface of the electronics structure, a second thermally conductive rail thermally conductively interfaced to the first rail, and a biasing mechanism biasing the second rail away from the first rail. The first and second rails and the biasing mechanism are configured for slidable insertion into a housing with the electronics structure, the housing containing a liquid-cooled cold plate(s). With insertion of the electronics structure into the housing, the second rail engages the liquid-cooled cold plate and is forced by the biasing mechanism into thermal contact with the cold plate, and is forced by the cold plate towards the first rail, which results in a compliant thermal interface between the electronics structure and the liquid-cooled cold plate of the housing.

摘要： Condenser structures and cooling apparatuses are provided which facilitate vapor condensation heat transfer of a coolant employed in cooling an electronic device. The condenser structure includes a thermally conductive condenser block with multiple exposed cavities therein extending from a first main surface towards a second main surface. The condenser block is a monolithic structure, and the first main surface is a coolant vapor condensate formation surface when the condenser structure is operationally facilitating cooling of an electronic device. The exposed cavities extend from the first main surface into the condenser block to increase a condensation surface area of the condenser block, thereby facilitating coolant vapor condensate formation on the condenser block, and thus cooling of the electronic device using a two-phase coolant. The condenser structure also includes coolant-carrying channels for facilitating cooling of the condenser block, and thus vapor condensate formation on the condenser block.

摘要： Liquid-cooled electronics racks and methods of fabrication are provided wherein a liquid-based cooling apparatus facilitates cooling of electronic subsystems when docked within the electronics rack. The cooling apparatus includes a liquid-cooled cooling structure mounted to a front of the rack, and a plurality of heat transfer elements. The cooling structure is a thermally conductive material which has a coolant-carrying channel for facilitating coolant flow through the structure. Each heat transfer element couples to one or more heat-generating components of a respective electronic subsystem, physically contacts the cooling structure when that electronic subsystem is docked within the rack, and provides a thermal transport path from the heat-generating components of the electronic subsystem to the liquid-cooled cooling structure. Advantageously, electronic subsystems may be docked within or undocked from the electronics rack without affecting flow of coolant through the liquid-cooled cooling structure.
