The invention relates to an electric reactor iron core structure. The structure comprises a magnetic core cake and a winding wound on the magnetic core cake, the winding comprises an insulation paper layer and an aluminum foil tape layer which are mutually staggered and stacked, the outer side wall of the magnetic core cake is coated with an epoxy resin layer, division bars are fixed to the four vertex angles of the magnetic core cake in a protruding mode, and the division bars are fixedly connected to the epoxy resin layer. The length direction of the division bars is parallel to the length direction of the magnetic core cake, the winding is wound on the division bar, and a first heat dissipation air channel is formed between the inner wall of the winding and the outer wall of the magnetic core cake; and mounting plates are arranged on the two opposite outer side walls of the magnetic core cake in a protruding mode, a plurality of partition plates are arranged on the mounting plates, the length direction of the partition plates is parallel to the length direction of the magnetic core cake, winding cavities allowing windings to penetrate through and be wound are formed between the partition plates and the partition strips and between every two adjacent partition plates on the same mounting plate, and second heat dissipation air channels are formed in the end faces of the partition plates in a penetrating mode. The structure has the advantage that the heat dissipation effect of the reactor is improved.
Description
technical field [0001] The present application relates to the technical field of reactor production, in particular to a reactor core structure, manufacturing equipment and a manufacturing method thereof. Background technique [0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electric conductors that can carry current have inductance in the general sense. According to the structure and cooling medium: divided into hollow type, iron core type, dry type, oil-immersed type, etc. [0003] Due to the wide application of reactors in power electronic components, the efficiency and power loss of reactors in various environments are also concerned by the industry, especially in high-frequency environments. The requirements are more stringent. [0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the structure of the r...
