Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically to an inductor ventilation and heat dissipation structure. Background Technology

[0002] The basic structure of an inductor includes a frame, windings, shielding, encapsulation material, and leads (pins). An inductor, also known as a choke, reactor, or dynamic reactor, is a magnetic electronic component that converts electrical energy into magnetic energy and stores it. The original model of an inductor is a cylindrical coil of wire. Its working principle is that when current flows through it, a magnetic field is generated. This magnetic field stores some electrical energy. When the current stops or changes direction, the magnetic field releases the stored energy, attempting to maintain a constant current flow.

[0003] The existing technology has the following problems:

[0004] In traditional inductors, the wires are directly wound around the frame, and during operation, a large number of wires come into contact with each other. This causes the temperature inside the wound wires to rise and accumulate, making it impossible to dissipate heat effectively. As a result, the inductor is damaged when the temperature rises to a certain level. Utility Model Content

[0005] This invention provides an inductive ventilation and heat dissipation structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An inductor ventilation and heat dissipation structure includes an inductor frame, which is cylindrical in shape. Circular baffles are fixedly connected to both the upper and lower ends of the inductor frame. Ventilation ports that communicate vertically are opened in the middle of the upper surface of both the upper and lower circular baffles and the upper surface of the inductor frame. Connecting components are provided on the inner walls of the vents. A plurality of heat dissipation components are fixedly connected to the outer surface of the inductor frame. A wire winding channel is formed between adjacent heat dissipation components. Each heat dissipation component includes four arc-shaped plates forming a ring. An arc-shaped groove that communicates vertically is opened on the upper surface of each of the four arc-shaped plates. A plurality of heat dissipation holes that communicate internally and externally are opened on the inner walls of the arc-shaped grooves.

[0008] A further improvement of this utility model is that a channel is formed between two adjacent arc-shaped plates, and the material of the four arc-shaped plates is copper.

[0009] A further improvement of the present invention is that the connecting component includes a heat-conducting plate, the length of which is the same as the height of the inductor frame and the thickness of the circular baffle. The left and right sides of the heat-conducting plate are fixedly connected to the inner wall of the vent. A transverse plate is fixedly connected to the lower surface of the heat-conducting plate, and a longitudinal plate is fixedly connected to the middle of the front and rear sides of the transverse plate.

[0010] A further improvement of this utility model is that the horizontal plate and the two vertical plates form a cross shape.

[0011] A further improvement of this utility model is that: a plurality of heat-conducting pillars are fixedly connected to the upper surface of the heat-conducting plate, and a circular heat sink is fixedly connected to the upper end of the plurality of heat-conducting pillars.

[0012] A further improvement of this utility model is that the circular heat sink and several heat-conducting pillars are positioned directly above the inductor frame.

[0013] A further improvement of this utility model is that the thickness of the heat-conducting plate is the same as the thickness of the horizontal plate.

[0014] A further improvement of this utility model is that the heat-conducting plate, the plurality of heat-conducting pillars, and the circular heat sink are made of copper.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides an inductor ventilation and heat dissipation structure, which adopts the cooperation of heat dissipation components, arc plates, arc grooves, and heat dissipation holes. After the wire is wound around the inductor frame, the wound wire contacts the four arc plates after operation. The arc plates transfer heat to the outside, while the arc grooves facilitate the transfer of heat from the wound wire to the inside and discharge it through the heat dissipation holes. Through this structure, the wound wire can dissipate heat, so that heat transfer and heat dissipation can be achieved, and heat accumulation cannot be caused.

[0017] 2. This utility model provides an inductive ventilation and heat dissipation structure, which adopts the cooperation of vent, connecting components, heat-conducting plate, horizontal plate, vertical plate, heat-conducting column, and circular heat sink.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 As shown, this utility model provides an inductive ventilation heat dissipation structure: the inductive ventilation heat dissipation structure includes an inductive frame 1, a circular baffle 2, a heat dissipation component 3, and a connecting component 5;

[0024] Inductor frame 1: As the basic support of the entire structure, the inductor frame 1 adopts a cylindrical design, with circular baffles 2 fixedly connected to both its upper and lower ends. The circular baffles 2 are made of insulating material. A vent 4 is opened in the middle of the upper surface of the inductor frame 1 to allow air circulation between the inside and outside and enhance the heat dissipation effect. The material of the inductor frame 1 is a metallic magnetic material. Circular baffle 2: The circular baffle 2 is fixedly connected to the upper and lower ends of the inductor frame 1, which facilitates the winding of the wires. It also forms an air circulation channel with the inductor frame 1 through the vent 4 opened on it.

[0025] Heat dissipation component 3: Heat dissipation component 3 is a key component for improving heat dissipation performance. It is fixedly connected to the outer surface of the inductor frame 1. Each heat dissipation component 3 consists of four arc-shaped plates 31, forming a ring structure to adapt to the cylindrical shape of the inductor frame 1. The upper surface of the arc-shaped plate 31 is provided with an arc-shaped through groove 32. The inner wall of the arc-shaped through groove 32 is distributed with several heat dissipation holes 33 that are connected inside and outside. The design of the arc-shaped through groove 32 and the heat dissipation holes 33 facilitates better heat dissipation of the wires during operation. The arc-shaped plate 31 directly transfers heat for heat dissipation, while the arc-shaped through groove 32 and the heat dissipation holes 33 allow heat between the wires to enter the interior and then be discharged to form secondary heat dissipation. A wire winding channel is formed between two adjacent heat dissipation components 3, which facilitates the winding of the inductor coil.

[0026] Connection component 5: Connection component 5 is located on the inner wall of vent 4 to further enhance heat dissipation. It mainly consists of a heat-conducting plate 51, a horizontal plate 52, a vertical plate 53, a heat-conducting pillar 54, and a circular heat sink 55. Heat-conducting plate 51: It is fixedly connected to the inner wall of vent 4, acting as a bridge to conduct heat from inside the inductor frame 1 to the outside. Horizontal plate 52 and vertical plate 53: They form a cross-shaped structure to support the inductor frame 1, allowing the vent 4 to vent vertically, facilitating better heat dissipation during operation. The horizontal plate 52 and vertical plate 53 are designed to facilitate connection and fixation to the circuit board via welding. Heat-conducting pillar 54 and circular heat sink 55: The heat-conducting pillar 54 further conducts heat from the heat-conducting plate 51 to the circular heat sink 55. The circular heat sink 55 increases heat dissipation efficiency by increasing the surface area. This structural design allows connection component 5 to not only effectively conduct heat but also facilitate vertical heat dissipation of the inductor frame 1.

[0027] Material: The arc plate 31 is made of copper, which has good thermal conductivity and can quickly conduct heat to the heat dissipation hole 33 to improve heat dissipation efficiency; the heat conduction plate 51, heat conduction pillar 54 and circular heat sink 55 are also made of copper, which enables efficient heat conduction and dissipation to meet heat dissipation requirements. The wires wrapped around the surface of the inductor frame 1 are made of copper, and after the wires are wrapped around the surface of the inductor frame 1, the two ends of the wires are fixed with pins, and the pins are soldered to the circuit board to form an electrical path.

[0028] Working principle: During use, the arc plate 31 directly transfers the heat in the wound wire to the outside. At the same time, the arc groove 32 and heat dissipation hole 33 achieve secondary heat dissipation of the wire and exhaust the heat. The heat conduction plate 51 facilitates heat conduction in the vent 4 in the inductor frame 1. The heat conduction column 54 and circular heat sink 55 facilitate further heat dissipation from the vent 4. The horizontal plate 52 and vertical plate 53 facilitate support for the inductor frame 1, so that the vent 4 can be vented from top to bottom, improving heat dissipation efficiency.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
