摘要： Augmenting air cooling of electronics system using a cooling fluid to cool air entering the system, and to remove the heat dissipated by the electronics. A cooled electronics system includes a frame with drawers containing electronics components to be cooled. The frame includes a front with an air inlet and a back with an air outlet. A cabinet encases the frame, and includes a front cover positioned over the air inlet, a back cover positioned over the air outlet, and first and second side air returns at opposite sides of the frame. At least one air moving device establishes air flow across the electronics drawers. The air flow bifurcates at the back cover and returns to the air inlet via the first and second side air returns and the front cover. An air-to-liquid heat exchanger cools the air flowing across the electronics drawers.

At least some wires reside partially over a first region of higher heat flux and extend partially over a second region of lower heat flux, wherein the first and second regions are different regions of the surface to be cooled. These wires function as thermal spreaders facilitating heat transfer from the surface to be cooled to the cooling assembly.

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.
