METHOD FOR DETERMINING HEAT-SINK SOILING BY MEANS OF ARTIFICIAL INTELLIGENCE

A method for determining soiling of a heat sink for cooling an electronic component is disclosed. A load curve controlled by the component and a temperature curve along a heat transfer chain from the at least one component to the heat sink are continuously captured. In a training phase, a decision f...

Summary:A method for determining soiling of a heat sink for cooling an electronic component is disclosed. A load curve controlled by the component and a temperature curve along a heat transfer chain from the at least one component to the heat sink are continuously captured. In a training phase, a decision function is determined, which is provided for application to a portion of the load curve and to at least one correspondingly captured portion of a temperature curve. In a classification phase, a non-soiled state of the heat sink is detected when the portion of the load curve presented to the decision function is similar to the portions of the load curve captured in the training phase and when the at least one corresponding portion of a temperature curve is similar to the portions of the temperature curve in question that were correspondingly captured in the training phase.
