NOVELTY - The utility model claims an iron core column structure, comprising a plurality of iron core column monomers, a plurality of laminated iron core column formed by stacking the iron core column monomer; the middle part of two sides of the laminated iron core column is connected with a radiating rod for helping cooling and conducting iron core column monomer heat through the groove on the iron core column monomer; the corner of the laminated iron core column is provided with a wrap angle; the iron core column monomer comprises an iron chip; the upper surface of the upper insulating layer is printed with a gas gap pad of graphene/barium ferrite (BaFe12O19) composite material. The air gap pad of the utility model is printed on the upper insulating layer of the iron core column monomer by printing; the connection is firm; it will not loose; it overcomes the problem that the gasket is inclined when manually installing the air gap; offset; the iron core flash gap and so on; the air gap pad is made of graphene/barium ferrite (BaFe12O19) composite material; it has excellent heat transfer effect, and uniformly distributed in the laminated iron core column; the liquid cooling reactor has good effect.
