“…As a new thermal management method, dynamic thermal management (DTM) [1,2] is put forward in the cooling system of electronic device that has strict demand of thermal control. The measurement of heat flux signal is important for DTM, since it can provide better thermal control accuracy and better control response performance than the traditional temperature signal [2]. The measurement of heat flux has been widely studied, which can be classified into three categories: the gradient method, the transient method, and active heating method [3].…”

Heat flux measurement is important for dynamic thermal management (DTM) since it can provide more predicted information. Commercial heat flux sensors are too expensive and fragile for practical applications. Thermoelectric Cooler (TEC) based DTM provides the possibility of measuring the heat flux without additional heat flux sensor. Soft measurement of TEC heat flux has been presented via Neural Network (NN), which is suitable for identifying TEC model. NN models have been proposed by combing the classical TEC model together. The soft measurement performances with different NN models have been reported and analyzed in terms of accuracy, efficiency, and generalization capability.
