The reactor and the transformer are electromagnetic induction components which are wound by insulated wires or foil conductors and insulating layers. When the reactor and the transformer work, the coil can generate continuous heat, the untimely consumption of the heat can influence the performance and the service life of the whole electromagnetic component, and even potential safety hazards are generated.

In the prior art, the heat dissipation mode for the electromagnetic component mainly increases the heat dissipation area of the coil and utilizes the heat conduction effect of the iron core. The heat dissipation is limited due to the part (industry term: window) of the coil blocked by the inherent structure of the iron core, and even more due to the principle of heat convection, the heat is dissipated upwards, and the temperature of the coil is highest in the part theoretically. Often causing excessive temperature rise and even burnout. Therefore, in design, the heat generated by loss is reduced by increasing the sectional area of the conductor and the sectional area of the iron core, and as a result, the product has high cost, large volume, heavy weight and the like.
