    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: A cooling apparatus and method are provided for cooling an electronic subsystem of an electronics rack. The cooling apparatus includes a local cooling station, which has a liquid-to-air heat exchanger and ducting for directing a cooling airflow across the heat exchanger. A cooling subsystem is associated with the electronic subsystem of the rack, and includes either a housing facilitating immersion cooling of electronic components of the electronic subsystem, or one or more liquid-cooled structures providing conductive cooling to the electronic components of the electronic subsystem. A coolant loop couples the cooling subsystem to the liquid-to-air heat exchanger of the local cooling station. In operation, heat is transferred via circulating coolant from the electronic subsystem and rejected in the liquid-to-air heat exchanger of the local cooling station to the cooling airflow passing across the liquid-to-air heat exchanger. In one embodiment, the cooling airflow is outdoor air.
