Abstract
Cooling apparatuses, cooled electronic modules, and methods of fabrication are provided which facilitate heat transfer from one or more electronic components to a liquid coolant in an operational mode, and drainage of coolant therefrom in a transport mode. The cooling apparatus includes a liquid-cooled heat sink configured to horizontally couple along a main heat transfer surface to the electronic component(s). The heat sink includes a thermally conductive structure with a coolant-carrying compartment through which coolant flows, and a coolant inlet tube and a coolant outlet tube affixed to the thermally conductive structure and in fluid communication with the coolant-carrying compartment to facilitate coolant flow through the compartment. The coolant-carrying compartment has a base surface, and the coolant outlet tube extends into the coolant-carrying compartment towards the base surface to facilitate withdrawal of the liquid coolant from the compartment in the transport mode of the cooling apparatus.
