Description

Technical Field

[0001] The utility model relates to the technical field of magnetic devices, in particular to an inductor structure of a charging pile. Background Art

[0002] With the development of electronic devices, communications, information technology, and new energy, the demand for functional materials in electronic devices continues to increase, and performance requirements are constantly improving. As one of the most popular functional materials in recent years, soft magnetic materials have attracted widespread attention. Soft magnetic materials, which are easily magnetized and demagnetized, are widely used in the power and electronics industries, primarily for information conversion, transmission, and storage.

[0003] Charging pile inductors are crucial electronic components. During the charging process, charging piles generate a significant amount of high-frequency noise and interference signals. If these signals are transmitted directly to the electric vehicle's battery, they could damage the battery. The filtering effect of the inductor effectively removes this high-frequency noise and interference, ensuring the stability and safety of the charging process. When charging an electric vehicle's battery, excessive current can cause dangerous conditions such as overcharging or overheating. The current limiting function of the inductor ensures that the charging current fluctuates within a reasonable range, protecting the battery from damage. Charging piles also generate a certain amount of electromagnetic radiation during operation. If this radiation exceeds a certain range, it may interfere with other nearby electronic devices. The magnetic shielding and electromagnetic interference resistance of the inductor can effectively reduce the electromagnetic radiation level of the charging pile, improving the electromagnetic compatibility of the entire system.

[0004] Inductors, also known as chokes, reactors, and dynamic reactors, are common electronic components in electrical devices. On circuit boards, you'll find spring-like coils—inductors. Inductors typically consist of a bobbin, windings, a shield, packaging materials, a core, or an iron core, and other magnetic components.

[0005] An inductor acts as a short circuit in a DC circuit, presenting high resistance to sudden current fluctuations. When DC flows through an inductor, it behaves like a wire, with no resistance. However, when encountering sudden current fluctuations, the inductor prevents these current fluctuations, maintaining a stable flow. This acts like a security guard for the circuit, ensuring a steady flow of current.

[0006] Based on this, Chinese patent CN207800328U discloses a charging pile inductor, which includes a magnetic core and a winding. The magnetic core includes an upper yoke, a lower yoke, a left core core, and a right core core. The left core core and the right core core are symmetrically arranged between the upper yoke and the lower yoke. The left side of the left core core is flush with the left side of the upper yoke and the lower yoke of the core, and the right side of the right core core is flush with the right side of the upper yoke and the lower yoke of the core. The winding includes a first winding wound on the left core core and a second winding wound on the right core core. In the inductor structure disclosed in this patent, it has only two cores, the magnetic core combination method is simple, and the consistency of the two cores is good; the winding is a flat wire vertical winding, and each layer of flat wire can directly contact the external air, which is easy to dissipate heat. The overall heat dissipation effect of the inductor is good and the temperature rise is low.

[0007] However, the charging pile inductor disclosed above still has the technical problem of poor heat dissipation. Specifically, the heat dissipation of the charging pile inductor is an important part of the charging pile design, because the inductor will generate a lot of heat during the charging process. If it is not dissipated in time, it may cause a safety accident. The main function of the charging pile is to replenish electric energy for electric vehicles in a relatively short period of time, especially DC fast charging, which can be fully charged within 1-2 hours. However, as the charging speed increases, the current and voltage will increase, causing components such as the inductor to generate a lot of heat. If the heat is not dissipated in time, the inductor temperature may increase, affecting the performance and life of the charging pile, and even causing a safety accident. Utility Model Content

[0029] Specifically, the utility model discloses a kind of charging pile inductance structure when working, the supporting base 1 is connected with the installation environment outside, such as external circuit board or the preset installation position of charging pile;After this, in the process that external charging pile charges externally, the magnetic core structure 3 generates energy loss in the magnetization process due to the turning and friction of magnetic domain, this part of loss will be converted into heat energy and released, resulting in the heating of magnetic core;In addition, in the alternating magnetic field formed by the magnetic core structure 3 and the coil structure 4, eddy current will be generated due to the change of magnetic flux. When eddy current flows in the magnetic core, it will generate resistance loss, which will also be converted into heat energy and released.
