Embodiment 1

[0021] Such as figure 1 Shown is a schematic diagram of the structure of the heat dissipation column in the present invention when the waist-shaped column is selected. The present invention is a magnetic core for wireless charging used in a vehicle power supply, including a magnetic core body and a heat dissipation column 1 installed in the middle of the magnetic core body; The magnetic core body includes a magnetic core base 2 combined into a semi-open whole and magnetic core legs 3 located on both sides; the inner surface of the magnetic core leg 3 is set as a leg spherical surface; the heat dissipation column 1 is vertically arranged on the magnetic base 2 In the middle of the surface, there are heat dissipation spherical surfaces corresponding to the spherical surfaces of the legs on both sides.

[0022] The heat dissipation column 1 is a waist-shaped column, and heat dissipation channels 6 are evenly distributed in the heat dissipation column 1. Both sides of the heat dis...

Embodiment 2

[0024] Such as figure 2 As shown, the main structure of this embodiment is the same as that of Embodiment 1, the difference is that: the heat dissipation column 1 is hemispherical; the spherical surface of the outrigger and the heat dissipation column have the same spherical center; Outrigger drainage grooves 4 and heat dissipation drainage grooves 5; outrigger drainage grooves 4 and heat dissipation drainage grooves 5 are arranged alternately.

Abstract

The invention provides a wireless charging magnetic core for a vehicle-mounted power supply. The wireless charging magnetic core comprises a magnetic core body and a heat dissipation column installedin the middle of the magnetic core body; the magnetic core body comprises a magnetic core base and magnetic core supporting legs located on the two sides of the magnetic core base, wherein the magnetic core base and the magnetic core supporting legs are combined into a semi-open whole; the inner side surfaces of the magnetic core supporting legs are supporting leg spherical surfaces; the heat dissipation column is vertically arranged in the middle of the surface of the magnetic base; and heat dissipation spherical surfaces corresponding to the supporting leg spherical surfaces are arranged onthe two sides of the heat dissipation column. According to the wireless charging magnetic core of the invention, the overall internal space of the magnetic core is increased, or the internal space structure of the magnetic core is changed, so that heat the dissipation effect of the magnetic core during operation is improved, and therefore, the temperature range characteristic of the magnetic coreis remarkably improved, it is guaranteed that the magnetic core still has good heat dissipation efficiency in a long-time working state, and charging efficiency and stability are kept.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a magnetic core for wireless charging used in a vehicle power supply. Background technique [0002] With the promotion of environmental protection concepts and the development of new energy technologies, electric vehicles are becoming more and more popular. An electric vehicle is a vehicle powered by an on-board power supply, driven by a motor to drive the wheels, and conforms to the requirements of road traffic and safety regulations. The on-board power supply is the most important part of the entire electric vehicle, and the charging and discharging of electric vehicles need to rely on inductive magnetic cores. At present, the charging methods of on-board power supplies are all direct-connected, but with the advancement of technology, on-board power supplies are gradually developing towards miniaturization and high power, and the requirements for charging...
