Abstract
It is increasingly common the presence of new technologies in the current automotive projects, with energy efficiency as the main objective, and, consequently, the reduction of fuel consumption. The majority of these technologies require a specific calibration for each vehicle, to enhance the efficiency of the component, maintaining the performance in acceptable limits. One of the newest technologies used at the cooling system is the fan controlled activated by PWM, aiding in the energy efficiency of the vehicle with less demand from the alternator. One of the problems faced by this component is its calibration, since the PWM Fan needs to fulfill its energetic function and reach the thermal balance performance targets as well. keeping the temperature at acceptable levels. At most of the times, the calibration of this component is done experimentally, in such a way that many tests need to be run until satisfying values to the calibratable parameters are found. The present work shows a computational method to calculate the optimum calibration parameters for the fan. This way, it is possible to find the optimum parameters in a faster and less expensive way, avoiding a large number of physical tests.
