Tool for fast modelling active heat sinks

The paper presents a tool for electrothermal simulations and very fast mode lling active heat sinks. The tool is based on a special electrothermal mode l of an active heat sink and makes use of the electronic circuit simulator SPICE. By its means one can find values of electrical current supplying a t hermo-electric device so as to change temperature of a cooled object accord ing to a given algorithm. The electrothermal model of an active heat sink, way of calculating control functions of a Peltier device supplying electric al current and examples of simulations are shown.
