Electrochemical sensor for sensing two-phase cooling fluid contamination

Abstract

An immersion cooling system includes an immersion tank defining an immersion chamber therein, an immersion working fluid, a first electrode, and a second electrode. The immersion working fluid is positioned at least partially in the immersion chamber. The first electrode is electrically coupled to an electrical power source, and the second electrode is positioned proximate to the first electrode and defines a sampling region therebetween. A sample portion of the immersion working fluid is positioned in the sampling region, and the second electrode is coupled to a microcontroller configured to measure at least a current across the sampling region between the first electrode and the second electrode.
