27884-2 A B S T R A C T A cell arrangement for electrometallurgical purposes, for example aluminum electrolysis. This arrangement provides a practical means for heat recovery as well as regulation and con- trol of the temperature conditions during cell operation. The cell arrangement comprises a cell box having an internal refract- ory lining in its bottom and walls, an anode, a heat exchanger comprising cooling chambers adapted to receive a circulating flow of a cooling medium which is regulated on the basis of signals from temperature sensor means connected to a system for tempera- ture control. The heat exchanger is directly incorporated in a closed circuit with an expansion engine, whereby the assembly of the heat exchanger, closed circuit and expansion engine is such that the cooling medium of the heat exchanger and the working medium of the expansion engine are the same fluid.
