Crystallizer cast ingot cooling equipment

The invention provides crystallizer cast ingot cooling equipment, and belongs to the field of manufacturing of forging auxiliary equipment. The cooling device comprises a plurality of cooling modules; each cooling module is of a circular tube-shaped structure; an annular heat conduction sleeve is arranged in an inner cavity of the cooling module. A plurality of vertical air inlet pipes and a plurality of vertical air outlet pipes are arranged in the annular heat conduction sleeve, and one air inlet pipe is arranged between every two adjacent air outlet pipes. Every two adjacent cooling modules are stacked in the vertical direction, and the air inlet pipe and the air outlet pipe are in butt joint. In each cooling module, the outer side of the annular heat conduction sleeve is sleeved with an annular water channel, and the annular water channel is provided with a water inlet pipe and a water outlet pipe; the plurality of cooling modules comprise a bottom module, a plurality of middle modules and a top module wh
