Thermal monitoring and analysis of conditions in a power electronic system include sensing of thermal parameters of interest, such as temperature and humidity in an enclosure housing power electronic components. The components are cooled by a liquid coolant flow from a chiller through chiller plates associated with the power electronic components. Air is circulated through the enclosure for heat rejection from the chiller plates. Based on the sensed parameters, factors such as relative humidity and dew point of the cooling air may be computed and evaluated to determine the potential for condensation. Alarms, notices, or recommendations may be output for regulation of the chiller to avoid condensation. The system may also provide for evaluation of installation errors, and degradation of performance over time.

An example ventilation system for a computing device includes: a cover slidably engageable with a housing of the computing device to a closed position defining an internal space of the computing device, the cover having first ventilation holes; a system mesh slidably engaged with the cover, the system mesh having second ventilation holes; and a stopper disposed in the internal space of the computing device, the stopper to stop the system mesh at a predefined position when the cover is engaged with the housing in the closed position, wherein the first ventilation holes and the second ventilation holes overlap to define system ventilation holes for the computing device.

An electronic device includes proximity sensor, a memory and a processor. The proximity sensor is positioned within an enclosure of the electronic proximate to one or more air vents. The proximity sensor generates a sensing signal to detect blockage of the one or more air vents.
