An infinite staged Ettingshausen cooler of exponential shape has been constructed, using an oriented single crystal of Bi97Sb3. The magnetic field of B=0.75 T was provided by a permanent magnet system. A maximal temperature difference ΔT=42 K was achieved maintaining the heat sink at T=160 K. Referring to the temperature range and magnetic field strength used, this result represents a large cooling effect for an Ettingshausen cooling device. A simulation program that takes into account the temperature dependence of the transport coefficients was developed. Not only the predicted maximal temperature difference but also the electrical current necessary to obtain this maximum are in reasonable agreement with experimental results.
