摘要： A heat exchanger door and heat exchanger core optimization method are provided. The door resides at an air inlet or outlet side of an electronics rack, and includes an air-to-coolant heat exchanger with a heat exchanger core. The core includes a first coolant channel coupled to a coolant inlet manifold downstream from a second coolant channel, and the first channel has a shorter channel length than the second channel. Further, coolant channels of the core are coupled to provide counter-flow cooling of an airflow passing across the core. The core optimization method determines at least one combination of parameters that optimize for a particular application at least two performance metrics of the heat exchanger. This method includes obtaining performance metrics for boundary condition(s) of possible heat exchanger configurations with different variable parameters to determine a combination of parameters that optimize the performance metrics for the heat exchanger.

摘要： A cooling unit and cooling method are provided for a container-type data center. The cooling unit includes a heat rejection unit, for rejecting heat from coolant passing through a coolant loop to air passing across the heat rejection unit, and a refrigeration unit controllable to selectively provide auxiliary cooling to at least a portion of the coolant passing through the coolant loop. The heat rejection unit includes a heat exchange assembly, having a first heat exchanger and a second heat exchanger, and one or more air-moving devices providing airflow across the first and second heat exchangers. The first heat exchanger couples in fluid communication with the coolant loop, and the second heat exchanger is coupled in fluid communication with a refrigeration loop of the refrigeration unit for rejecting heat from refrigerant passing through the refrigeration loop to the airflow passing across the second heat exchanger.

摘要： Thermoelectric-enhanced air and liquid cooling of an electronic system is provided by a cooling apparatus which includes a liquid-cooled structure in thermal communication with an electronic component(s), and liquid-to-liquid and air-to-liquid heat exchangers coupled in series fluid communication via a coolant loop, which includes first and second loop portions coupled in parallel. The liquid-cooled structure is supplied coolant via the first loop portion, and a thermoelectric array is disposed with the first and second loop portions in thermal contact with first and second sides of the array. The thermoelectric array operates to transfer heat from coolant passing through the first loop portion to coolant passing through the second loop portion, and cools coolant passing through the first loop portion before the coolant passes through the liquid-cooled structure. Coolant passing through the first and second loop portions passes through the series-coupled heat exchangers, one of which functions as heat sink.

摘要： An air-cooling apparatus is provided which includes a securing mechanism for holding two or more separate electronics racks in fixed relation adjacent to each other, and a multi-rack door sized and configured to span the air inlet or air outlet sides of the racks. The securing mechanism holds the electronics racks in fixed relation with their air inlet sides facing a first direction, and air outlet sides facing a second direction. The door includes a door frame with an airflow opening. The airflow opening facilitates the ingress or egress of airflow through the electronics racks, and the door further includes an air-to-liquid heat exchanger supported by the door frame, and disposed so that air flowing through the airflow opening passes across the heat exchanger. In operation, the heat exchanger extracts heat from the air passing through the separate electronics racks.

摘要： A cooling apparatus for an electronics rack is provided which includes an air-to-liquid heat exchanger, one or more coolant-cooled structures and a tube. The heat exchanger, which is associated with the electronics rack and disposed to cool air passing through the rack, includes a plurality of distinct, coolant-carrying tube sections, each tube section having a coolant inlet and a coolant outlet, one of which is coupled in fluid communication with a coolant loop to facilitate flow of coolant through the tube section. The coolant-cooled structure(s) is in thermal contact with an electronic component(s) of the rack, and facilitates transfer of heat from the component(s) to the coolant. The tube connects in fluid communication one coolant-cooled structure and the other of the coolant inlet or outlet of the one tube section, and facilitates flow of coolant directly between that coolant-carrying tube section of the heat exchanger and the coolant-cooled structure.

摘要： An apparatus determines cooling characteristics of an operational cooling device used for transferring heat from an electronic device. The operational cooling device is thermally coupled to a heat pipe. The heat pipe has an exposed surface for selective application of heat thereon. Heat from a localized heat source is selectively applied to at least one region of the exposed surface. The heat source is preferably capable of being varied both positionally relative to the exposed surface and in heat intensity. A heat shield is preferably positioned around the exposed surface of the heat pipe to isolate the operational cooling device from the heat from the localized heat source. A temperature detector repeatedly measures a temperature distribution across the exposed surface while the cooling device is in a heat transfer mode. The temperature distribution is then used to thermally characterize the operational cooling device.
