A cathode for a power module of the type including a consumable electrode. The cathode includes a face plate and a back plate with the face plate having a face surface defined by a plurality of horizontal ribs separated by grooves which function to present an electrolyte under controlled flow conditions to the inner face between the cathode and the anode. The rear surface of the face plate has electrolyte inlet and outlet passages therein extending generally at right angles to the grooves and opening into the grooves in the form of metering slots. The back plate is constructed for communication with inlet and outlet manifolds and provides inlet and outlet passages aligned with like passages in the face plate to effect a constant supply of electrolyte for circulation along the face surface of the face plate, as well as an ample outlet and return arrangement.
A cathode face plate for a power module of the type including a consumable anode, said cathode face plate including a face surface and a rear surface, said face surface substantially in its entirety defining a plurality of adjacent parallel continuous anode contacting ribs having parallel electrolyte circulating path defining grooves therebetween, a plurality of separate parallel inlet and discharge passage means arranged in alternating relation in said rear surface transversely of said grooves for respectively supplying and discharging an electrolyte, the combined depths of said grooves and said passage means being greater than the thickness of said face plate with said passage means intersecting said grooves in flow controlling slots.
A cathode for a power module of the type including a consumable anode, said cathode comprising a face plate including a face surface and a rear surface, said face surface defining a plurality of adjacent anode contacting ribs having electrolyte circulating path defining grooves therebetween, and a plurality of inlet and discharge passages in said rear surface transversely of said grooves, the combined depths of said grooves and said passages being greater than the thickness of said face plate with said passages intersecting said grooves in flow controlling slots, a back plate having a front surface in opposing sealed relation to said face plate rear surface, said back plate having inlet and outlet passages aligned with said inlet and outlet passages in said face plate and of a materially greater capacity.
A cathode for a power module of the type including a consumable anode, said cathode comprising a face plate including a face surface and a rear surface, said face surface defining a plurality of adjacent anode contacting ribs having electrolyte circulating path defining grooves therebetween, and a plurality of inlet and discharge passages in said rear surface transversely of said grooves, tthe combined depths of said grooves and said passages being greater than the thickness of said face plate with said passages intersecting said grooves in flow controlling slots;
