Popis: The physical model of the thermoelement in the unsteady cooling mode is considered. The heat capacity of the cooling object and the connecting and insulating plates, the heat load, the heat exchange with the ambient, the release of the Joule heat due to the presence of contact resistance between the thermoelectric material and the metallic connecting plate, as well as the Thomson effect impact in the bulk of thermoelement legs are taken into account. A method is described for calculating the optimal dependence of the thermoelement supply current on time, which provides the preset time dependence of the cooling temperature. Examples of computer simulation of current control functions for implementation of the specified time functions of operating temperature in medical devices are given.
