  • Electrolytic Cell With a Heat Exchanger
    Publication number: 20080271996
    Abstract: This invention relates to electrolytic cells used for production of aluminium. The side walls (8) of the pot surrounding its crucible (4, 4?) include a part (13) made of a porous material over at least one fraction of their height and/or their thickness, to enable a heat transfer gas to circulate, the part (13) made of a porous material being connected to heat transfer gas inlet means (15) and outlet means (16), so as to make a heat exchanger in order to recover heat energy lost through the sides of the pot.
