    摘要： 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.

    摘要： A spot welding-type system is provided adapted to facilitate evaluating a rechargeable battery. The system includes first and second electrodes to contact the rechargeable battery. The first electrode includes a first contact surface to facilitate inducing an internal short circuit within the rechargeable battery during operation of the spot welding-type system, and the second electrode includes a second contact surface to contact the rechargeable battery. The first and second contact surfaces are dissimilar contact surfaces, and the second contact surface is larger than the first contact surface. The system with the rechargeable battery disposed between the first and second contact surfaces produces, in operation, a localized pressure on, and a localized heating of, the rechargeable battery in a spot-sized region where the first contact surface contacts the rechargeable battery to facilitate generating and evaluating a potential internal short circuiting of the rechargeable battery.

    摘要： A heat sink and method of fabrication are provided for removing heat from an electronic component(s). The heat sink includes a heat sink base and frame. The base has a first coefficient of thermal expansion (CTE), and includes a base surface configured to couple to the electronic component to facilitate removal of heat. The frame has a second CTE, and is configured to constrain the base surface in opposing relation to the electronic component, wherein the first CTE is greater than the second CTE. At least one of the heat sink base or frame is configured so that heating of the heat sink base results in a compressive force at the base surface of the heat sink base towards the electronic component that facilitates heat transfer from the electronic component. A thermal interface material is disposed between the base surface and the electronic component.

    摘要： An air-to-coolant heat exchanger for an electronics rack is provided, which includes first and second tube segments, one or more connector segments, and a plurality of thermally conductive fins attached to the tube segments. The first tube segment includes a first inner tube positioned within a first outer tube, defining a first inner coolant-carrying channel and first outer coolant-carrying channel, and the second tube segment has a second inner tube positioned within a second outer tube, defining a second inner coolant-carrying channel and second outer coolant-carrying channel. The connector segment(s) couples in fluid communication at least one of the first and second inner coolant-carrying channels, or the first and second outer coolant-carrying channels. The heat exchanger is coupled to separately receive a first coolant and a second coolant, with the first coolant passing through the inner channels, and the second coolant through the outer channels.

    摘要： A battery pack is provided which includes an enclosure. The enclosure includes a battery cell compartment and a vent. The battery cell compartment is a sealed compartment, except for the vent, and the vent facilitates pressure-induced venting of gas from the battery cell compartment. One or more battery cells are disposed within the battery cell compartment, and the battery pack also includes a filter system associated with the enclosure. The filter system filters the pressure-induced venting of gas from the battery cell compartment resulting from a thermal runaway event at a battery cell of the one or more battery cells within the battery cell compartment of the enclosure.
