    Abstract: Thermoelectric-enhanced, rack-level cooling of airflow entering an electronics rack is provided by a cooling apparatus, which includes: an air-to-liquid heat exchanger; a coolant loop coupled to the heat exchanger, the coolant loop including a first loop portion and a second loop portion, where the heat exchanger exhausts heated coolant to the first loop portion and receives cooled coolant from the second loop portion. The cooling apparatus further includes a heat rejection unit and a thermoelectric heat pump(s). The heat rejection unit is coupled to the coolant loop between the first and second loop portions, and provides partially-cooled coolant to the second loop portion. The thermoelectric heat pump is disposed with the first and second loop portions coupled to opposite sides to transfer heat from the partially-cooled coolant within the second loop portion to provide the cooled coolant before entering the air-to-liquid heat exchanger.

    Abstract: An automated multi-fluid cooling method is provided for cooling an electronic component(s). The method includes obtaining a coolant loop, and providing a coolant tank, multiple valves, and a controller. The coolant loop is at least partially exposed to outdoor ambient air temperature(s) during normal operation, and the coolant tank includes first and second reservoirs containing first and second fluids, respectively. The first fluid freezes at a lower temperature than the second, the second fluid has superior cooling properties compared with the first, and the two fluids are soluble. The multiple valves are controllable to selectively couple the first or second fluid into the coolant in the coolant loop, wherein the coolant includes at least the second fluid. The controller automatically controls the valves to vary first fluid concentration level in the coolant loop based on historical, current, or anticipated outdoor air ambient temperature(s) for a time of year.

    Abstract: Cooling apparatuses and methods are presented for facilitating dissipation of heat generated by one or more electronic components. The apparatuses include, for instance, a coolant-cooled heat sink and a thermostat-controlled valve. The heat sink includes one or more coolant-carrying channels and one or more valve wells intersecting the channels. The thermostat-controlled valve is disposed, at least partially, within a respective valve well so as to intersect a respective coolant-carrying channel, and includes a valve disk and a thermal-sensitive actuator mechanically coupled to rotate the valve disk. The valve disk is rotatable between an open position where coolant is allowed to flow through the respective coolant-carrying channel, and a closed position where coolant is blocked from flowing through the respective channel. The actuator rotates the valve disk between the open position and the closed position, dependent on heating of the thermal-sensitive actuator by the electronic component(s).
