The invention provides a nodular cast iron isothermal quenching cooling device, and belongs to the field of heat treatment. The invention particularly relates to a cooling device for cooling a quenching medium after heat treatment of ductile iron. Comprising a salt bath medium circulating system and a cooling integrated pipe arranged on the circulating system, the cooling integrated pipe comprises a plurality of sets of cooling pipes which are integrally arranged, the cooling pipes are correspondingly provided with first fluid channels and second fluid channels, the first fluid channels are arranged on the outer sides of the second fluid channels in a wrapping mode to form composite cooling, and the second fluid channels are arranged on the outer sides of the second fluid channels in a wrapping mode. The cooling integrated pipe is provided with a stock solution leading-in channel, one end of the stock solution leading-in channel is correspondingly communicated with the solution increasing pipe set, the other
