Abstract
An anode cooling table for supporting anodes during cooling, has: a frame; a heat absorbing layer defining a substantially continuous surface for being contacted with the anodes; and a heat diffusing layer in contact with the frame and disposed between the frame and the heat absorbing layer, the heat absorbing layer in heat exchange relationship with the frame through the heat diffusing layer.

An anode cooling table for supporting hot spent anodes during cooling, comprising:
- a frame;
- a plurality of heat-conducting slabs secured to the frame, the plurality of heat-conducting slabs made of a material having a heat capacity of at least 500 J/kg*K, the heat-conducting slabs extending from top faces for contacting the anodes to bottom faces opposed to the top faces and oriented toward the frame;
- and
- a heat-transfer path extending from the top faces to an environment around the anode cooling table by conduction through a heat absorbing layer and by convection and/or radiation to the environment via a heat diffusing layer in heat exchange relationship with the heat absorbing layer.
