On the modelling of thermomagnetic cooling

The existence of Bi-Sb alloys with thermomagnetic properties allows to consider the construction of some thermomagnetic cooler operating at a temperature of about 100 K. The optimization of such a device, that is a very difficult experimental task, may be solved using a computer modelling. This paper proposes the analysis of the thermal flux inside the cooler with a new set of boundary conditions. It becomes possible to predict the conditions to achieve the greatest temperature difference with the device. (author) 4 figs., 4 refs
