Abstract:
1. A method of fabricating a cooling apparatus comprising: providing a liquid-cooled structure, the liquid-cooled structure being configured to couple to at least one electronic component to be cooled; providing a coolant loop, the coolant loop comprising a first loop portion and a second loop portion, the first loop portion and the second loop portion being parallel portions of the coolant loop; coupling the liquid-cooled structure in fluid communication with the first loop portion of the coolant loop; providing a liquid-to-liquid heat exchanger and an air-to-liquid heat exchanger coupled in series fluid communication via the coolant loop, wherein coolant egressing from the liquid-to-liquid heat exchanger passes, via the coolant loop, through the air-to-liquid heat exchanger; and providing a thermoelectric array comprising at least one thermoelectric module, the thermoelectric array being disposed with the first loop portion of the coolant loop at least partially in thermal contact with a first side of the thermoelectric array, and the second loop portion of the coolant loop at least partially in thermally contact with a second side of the thermoelectric array, wherein the thermoelectric array operates to transfer heat from coolant passing through the first loop portion to coolant passing through the second loop portion, the thermoelectric array cooling coolant passing through the first loop portion before the coolant passes through the liquid-cooled structure, and after passing through the liquid-cooled structure, the coolant passing through the first loop portion and the coolant passing through the second loop portion pass through the series-coupled, liquid-to-liquid heat exchanger and air-to-liquid heat exchanger, wherein one of the liquid-to-liquid heat exchanger or the air-to-liquid heat exchanger operates as heat sink for the coolant loop, dependent on a mode of operation of the cooling apparatus.
