Popis: This article presents a novel alternative for measuring the heat power generated by microelectronic devices during their designing stages. The proposed system is comprised of an uncommon geometry and a signal-processing measuring strategy based on the calorimetric principle and natural convection. The calorimeter is nonconventional compared to others proposed in the literature because it does not require an external power supply or internal moving parts. Therefore, this device features a low-cost operation. In addition, the calorimeter’s geometry and design make able to be implemented at any place, as well as enhancement-adaptable. Furthermore, the thermal behavior is studied based on experimental data and numerical simulations to characterize the system properly. Thus, the calorimeter is modeled as a Cauchy problem by an ordinary differential equation to find the transient time constant. Several testing devices ranging from 1 to 20 W were used. Therefore, an algorithm was developed to determine the net heat power in a reduced time. The slowest procedure identified using the proposed algorithm is a 1-W device with less than a half-time constant. Finally, the time reduction when employing devices with power dissipation higher than 20 W is also discussed.
