The invention discloses a water-cooling coil pipe type integral cast aluminum anode for aluminum electrolysis. The water-cooling coil pipe type integral cast aluminum anode is characterized by mainly consisting of an aluminum anode main body (1), more than one anode monomer (2) formed on the aluminum anode main body (1) and a cooling coil pipe (3) arranged inside ach anode monomer (2), wherein the cooling coil pipes (3) inside all anode monomers (2) are respectively formed together with independent water inlets and water outlets on the top of the aluminum anode main body (1). According to the water-cooling coil pipe type integral cast aluminum anode for aluminum electrolysis, the conventional aluminum guide rod, a steel claw and a carbon anode of different materials are cast by pure aluminum, so that a cast integer is formed, and therefore, not only can the defect that greater voltage drop on the joint of the conventional aluminum guide rod and the steel claw, and the joint of the steel claw and the carbon anode be overcome, but also the current impedance can be smaller to ensure that the voltage drop of the whole anode conductive part is reduced by over 200 millivolts as the materials of the steel claw and the carbon block are changed into aluminum material.
