Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an inductor for a micro ultra-thin mobile electronic device. Background Art

[0002] An inductor is a device that works on the principle of electromagnetic induction. When current flows through a wire, it generates a certain electromagnetic field around the wire, and the wire itself in this electromagnetic field will induce the wires within the range of this electromagnetic field. As electronic products develop towards smaller, thinner and lighter, the inductor as a basic circuit will also develop in the direction of smaller and thinner.

[0003] Existing Chinese patent document CN202022767503.5 discloses an inductor with a long service life, comprising a mounting plate, the right side of the top of the mounting plate being fixedly connected to the inductor body, the left side of the top of the mounting plate being movably connected to a rotating rod, the bottom of the surface of the rotating rod being sleeved with a rotating disk, both sides of the top of the rotating disk being provided with a first hand wheel, the bottom of the first hand wheel being fixedly connected to a first threaded rod, and the top of the mounting plate and both sides of the rotating rod being provided with slots for use with the first threaded rod. The utility model solves the problem of the short service life of existing inductor coils by providing a mounting plate, an inductor body, a rotating rod, a rotating disk, a first hand wheel, a first threaded rod, a slot, a limiting shell, a second hand wheel, a second threaded rod, a pressure block, a rotating frame, an adjusting box, a third hand wheel, a third threaded rod, a threaded sleeve and an adjusting rod. The inductor coil has the advantage of a long service life and is worthy of promotion.

[0004] However, the above patent has certain defects when used. During use, the inductor will generate heat due to the principle of electromagnetic induction. Long-term use will cause the inductor coil to overheat, thereby damaging the electronic equipment. The inductor coil of the device relies solely on natural cooling, and the cooling effect is insufficient, which greatly reduces the service life of the device.

[0005] Therefore, a micro ultra-thin inductor for mobile electronic devices is proposed to solve the above-mentioned problems. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides an inductor for a micro ultra-thin mobile electronic device.

[0007] The utility model is implemented by the following technical solutions:

[0008] A miniature ultra-thin mobile electronic device inductor comprises a magnetic powder body, an inner body, a coil, and a heat sink. The inner body is provided with a winding post, which is integrally connected to the inner body. The inner body is T-shaped. Two coils are arranged in sequence, one above the other, and fixed to the front of the inner body. One end of each coil extends outward and is fixed to the back of the body.

[0009] The magnetic powder body is wrapped around the outside of the inner body, covering the inner body and the coil completely. The heat sink is fixed on the bottom of the magnetic powder body, and the heat sink is used for heat dissipation of the device.

[0010] The heat sink is hollow inside and is filled with coolant.

[0011] The surface of the heat dissipation plate is provided with a plurality of heat dissipation grooves, and the heat dissipation grooves are evenly and equidistantly arranged.

[0012] The coil is a flat coil.

[0013] A groove is provided on one side of the magnetic powder body away from the heat dissipation plate, electrodes are provided on both sides of the groove, and the electrodes are connected to the coil.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a heat sink on the inductor, the interior of the heat sink is hollow and filled with coolant, combined with the design of the surface heat dissipation groove, the heat dissipation performance of the inductor is greatly improved, ensuring the stable operation of the inductor in a high temperature environment;

[0016] 2. The flat coil design reduces resistance and inductance losses and improves the electrical performance of the inductor. The "T"-shaped internal body and flat coil design achieve miniaturization and thinning of the inductor, meeting the needs of micro and ultra-thin electronic devices.

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a miniature ultra-thin mobile electronic device inductor includes a magnetic powder body 1, an internal body 6, a coil 5 and a heat sink 4. The internal body 6 is provided with a winding post 61, which is integrated with the internal body 6 to provide a stable support structure for the coil 5. The winding post 61 is the basis for winding the coil 5. Its shape and position determine the layout and inductance value of the coil 5. Through the winding post 61, the coil 5 can be evenly distributed on the internal body 6 to form the desired inductance effect.

[0026] The internal body 6 is in a "T" shape, and there are two coils 5, which are arranged in sequence from top to bottom and fixed on the front side of the internal body 6. One end of each coil 5 is extended and fixed on the back side of the body. This design optimizes space utilization and reduces the overall thickness. The internal body 6 is usually made of non-magnetic or low-magnetic material to avoid interference with the magnetic field. The design of its "T"-shaped structure is based on the principles of electromagnetics and mechanical design, and aims to provide the largest coil 5 winding space and stability with the smallest volume.

[0027] The magnetic powder body 1 is wrapped around the outside of the internal body 6, completely covering the internal body 6 and the coil 5. The magnetic powder body 1 not only protects the internal components, but also enhances the inductance of the inductor through its magnetic properties. The heat sink 4 is fixed to the bottom of the magnetic powder body 1. The heat sink 4 is used for heat dissipation of the device and for improving the heat dissipation performance of the inductor.

[0028] The heat sink 4 is hollow inside and filled with coolant. The circulation of the coolant can effectively reduce the working temperature of the inductor, thereby ensuring the long-term stable operation of the inductor.

[0029] The surface of the heat dissipation plate 4 is provided with a plurality of heat dissipation grooves 41 , which are evenly and equidistantly arranged. These heat dissipation grooves 41 can increase the heat dissipation area and further improve the heat dissipation efficiency.

[0030] The coil 5 is a flat coil 5 , which not only reduces the volume of the coil 5 , but also reduces resistance and inductance losses, thereby improving the electrical performance of the inductor.

[0031] The surface of the magnetic powder body 1 facing away from the heat sink 4 is provided with a groove 3. Electrodes 2 are located on either side of the groove 3. These electrodes 2 are connected to the coil 5, facilitating the installation of the inductor and connection to external circuits. The groove 3 design facilitates the installation and securement of the electrodes 2 while ensuring a reliable and stable connection. The electrodes 2 are typically made of a highly conductive material, such as copper or silver. They are connected to the coil 5 by welding or crimping, forming a complete circuit path.

[0032] The working principle of the present invention is as follows: when in use, as the current continues to flow and the magnetic field continues to change, a certain amount of heat is generated inside the inductor, and the heat sink 4 begins to work, and the coolant inside it absorbs and takes away the heat generated by the inductor through circulation;

[0033] At the same time, the heat dissipation grooves 41 on the surface of the heat dissipation plate 4 increase the heat dissipation area and improve the heat dissipation efficiency.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
