The thermal equilibrium system of the electrolyzer was chosen to be the closed physical interface between the aluminum cell and the environment, ie the slot top, the slot cover, the slot shell, and the bottom of the tank, including the ribs and cradle at the interface. The heat flow was calculated in unit time Of the electric power kilowatts (Kw) as a unit.



In order to accurately measure the loss of heat dissipation in the aluminum electrolytic bath system, it is necessary to divide the virtual area and arrange the measuring points on the surface of the tank system according to the warp-weft. The side surface of the cathode channel shell is divided into a melt region (electrolyte + aluminum liquid), a cathode carbon block region and a refractory heat retaining region in the latitudinal direction, and a cradle frame is used as a warp to form a measurement point region. For the slot cover, the bottom of the groove and the top of the slot using the same method for regional division and distribution measurements. In addition, the measuring point also includes protruding or exposing the system surface of the cradle, anode rod, cathode steel rods and along the plate and other cooling components.
