Claim:
1. A liquid-cooled system for a platform with air cooling, comprising: an electrical system comprising first and second electrical assemblies, the first electrical assembly comprising a first electrical component, the second electrical assembly comprising a second electrical component; a cooling unit housing comprising an air inlet duct, an air outlet duct, a first heat exchanger comprising a first air inlet and a first air outlet, and a second heat exchanger comprising a second air inlet and a second air outlet, the second heat exchanger being arranged in series with the first heat exchanger, wherein air from the air inlet duct flows into the first air inlet of the first heat exchanger and out of the first air outlet of the first heat exchanger, and wherein air from the first air outlet of the first heat exchanger flows into the second air inlet of the second heat exchanger and out of the second air outlet of the second heat exchanger to the air outlet duct; a first liquid loop passing through the first heat exchanger and the first electrical assembly; a first controllable pump for causing fluid circulation throughout the first liquid loop and the first electrical assembly; a second liquid loop passing through the second heat exchanger and the second electrical assembly; a second controllable pump for causing fluid circulation throughout the second liquid loop and the second electrical assembly; and a thermal barrier comprising a non-metal material between the first and second heat exchangers, the thermal barrier being separate from the air inlet duct and the air outlet duct, the thermal barrier defining a passage configured to contain and direct air flow between the first outlet of the first heat exchanger and the second inlet of the second heat exchanger, the thermal barrier comprising a portion extending continuously from the passage to a position between the first and second controllable pumps, wherein the first electrical component is more thermally sensitive than the second electrical component, wherein the first electrical component and the first heat exchanger are proximate to the air inlet duct and the second electrical component and the second heat exchanger are proximate to the air outlet duct, and wherein the first liquid loop is substantially thermally isolated from the second liquid loop by the thermal barrier.
