Cooling module with leak detector and related systems
In some respects, concepts disclosed herein generally concern systems, methods and components to detect a presence of a liquid externally of a desired primary flow path through a segment of a fluid circuit, e.g., throughout a cooling loop. Some disclosed concepts pertain to systems, methods, and components to direct seepage or leakage of a liquid coolant toward a lead-detection sensor. As but one example, some disclosed liquid-cooled heat exchangers incorporate a leak-detection sensor, which, in turn, can couple with a computing environment that monitors for detected leaks, and, responsive to an indication of a detected leak, invokes a task to control or to mitigate the detected leak.
1. A liquid-cooled heat exchanger configured to cool a heat-dissipation component by transferring heat dissipated by the heat-dissipation component to a liquid coolant in the heat exchanger, the heat exchanger comprising:
a heat sink having a first major surface defining a region configured to be placed into thermal contact with a corresponding surface of a heat-dissipation component, wherein such thermal contact conductively transfers heat from the heat-dissipation component to the heat sink, wherein the heat sink has a second major surface positioned opposite the first major surface;
a housing assembly coupled with the heat sink, defining an internal passageway configured to direct a flow of liquid coolant over the second major surface of the heat sink, wherein such flow of liquid coolant convectively transfers heat from the heat sink to the liquid coolant;
a peripheral channel extending at least partially around the region of the first major surface configured to be placed into thermal contact with the heat-dissipation component; and
a liquid-detection sensor positioned in the peripheral channel.
