Low-Temperature Ettingshausen Coolers
With recent advances in materials technology, a new means of solid state cooling in the 77° to 200°K temperature range now shows a great deal of promise. This method of cooling is based upon an effect first observed in 1887 by the German physicist, Ettingshausen. He found that when a magnetic field exists perpendicular to an electrical current flowing in a conductor, a transverse temperature gradient is observed which is perpendicular to both the current flow and the magnetic field.
