Abstract

The invention relates to a preparation method of a coil structure and a magnetic element. The preparation method comprises the following steps: S1, arranging an insulating partition plate and a right side jig on a left side jig in a sleeving mode in sequence; S2, providing a winding wire, and winding the winding wire in a winding gap between the jig and the insulating partition plate to form a flat coil; S3, performing heat setting on the flat coil, the insulating partition plate and the jig; S4, disassembling the jig to obtain a coil assembly, wherein the flat coil is fixed to the insulating partition plate; S5, fixedly connecting the insulating partition plate with a positioning block, and putting the coil assembly and the positioning block into a glue pouring cavity matched with the coil assembly and the positioning block; S6, filling the glue pouring cavity with pouring glue at a time; S7, after the pouring glue is shaped, obtaining the full-glue-pouring type coil structure.

Description

technical field [0001] The invention relates to the technical field of magnetic elements, in particular to a method for preparing a wire-wrap structure and a magnetic element including the wire-wrap structure. Background technique [0002] Some high-power magnetic components, such as transformers and inductors in vehicle charging systems, need a very good heat conduction path to export the temperature rise on the winding and magnetic core to the cooling system during operation. This is usually done by pouring thermal paste. Moreover, in order to achieve a better heat conduction effect, it is necessary to fill as much heat conduction glue as possible between the magnetic core and the winding. In terms of electrical characteristics, it is usually required: (1) between the windings and between the windings and the magnetic core must be able to withstand sufficient withstand voltage; (2) There are stable inductance, mutual inductance, leakage inductance, etc. between the windin...
