The use of the Ettingshausen effect in refrigeration is considered. The phenomenological similarity of this cooling effect with the cooling by a cascade of Peltier couples is treated. Theoretical expressions are derived for the maximum cooling that is possible with the Ettingshausen effect, and it is shown that the optimum shape of the cooling element is an exponential of a given form. Preliminary experiments with bismuth alloys have given a cooling of about 0.25°C.
