Abstract

This paper shows by numerical simulation that addition of fins to a thermal sensor may be a convenient way to improve its time response. Fins are of usefulness when the heat exchange sensor-ambient is a rather poor one. In the present work the fin performances of configurations of interest are evaluated with the aid of an standard finite element package. Typical responses of sensor to a step function are given. The numerical results helps to establish criteria of engineer utility. 1 Introduction Time response of a thermal sensor depends on its inner structure and the characteristic of the heat exchange between the sensor itself and the ambient. By means of a simplified analysis, considering the sensor
