Document Type and Number:
WIPO Patent Application WO/2024/037177
Kind Code:
A1
Abstract:
Provided are a winding device (10), a transformer, and an inductor. The winding device (10) comprises a plurality of metal sheet conductors (11) which are sequentially stacked to form the winding device (10), wherein each metal sheet conductor (11) is provided with a polyimide film layer (12) formed by an electrophoresis process. The film layer arranged on each metal sheet conductor (11) in the winding device (10) is a polyimide film layer (12) formed by an electrophoresis process, so that the thickness of the insulating film layer (12) on the outer surface of each metal sheet conductor (11) is greatly reduced, thereby reducing the overall size of the winding device (10), and making the structure of the winding device (10) more compact. In addition, the polyimide film layer (12) has good insulation, heat resistance, corona resistance, and the like, so that the space occupied by the winding device (10) can be greatly reduced while the winding device (10) has good working performance, thereby facilitating the miniaturization and high performance of the winding device (10), and thus facilitating wider application of the winding device (10).
