Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and more specifically, to an adjustable multilayer heat dissipation inductor. Background Technology

[0002] Inductors are important components in electronic circuits and are widely used in power supply, filtering, oscillation and other circuits. When an inductor is working, the current passing through the coil will generate heat. Especially under high frequency and high current conditions, the heating phenomenon of inductors is more obvious. The heat dissipation structure of traditional inductors is relatively simple and the heat dissipation efficiency is low. A large amount of heat accumulation will not only lead to the deterioration of the inductor's own performance, such as inductance drift and increased loss, but may also affect the normal operation of surrounding electronic components and even shorten the service life of the entire electronic device.

[0003] Furthermore, in practical applications, different circuit requirements often necessitate inductors with different inductance values. Existing adjustable inductors typically have complex adjustment methods and limited adjustment accuracy, making it difficult to meet diverse circuit design needs. Moreover, some adjustable inductors are prone to problems such as poor contact during adjustment, leading to unstable inductance values ​​and affecting the normal operation of the circuit.

[0004] Utility model patent CN215988330U discloses a continuously adjustable variable inductor, including a housing, a frame fixedly disposed in the middle of the inner wall of the housing, an induction coil disposed on the surface of the frame, a magnetic core inserted through the middle of the frame, a movable plate fixedly connected to the top of the magnetic core, a rotating seat fixedly disposed in the middle of the top of the movable plate, a temperature sensor embedded on one side of the bottom of the movable plate, a cooling fan fixedly mounted at the bottom of the frame, a semiconductor cooling chip fixedly disposed in the middle of the bottom of the cooling fan, and several heat sinks fixedly connected to the bottom of the semiconductor cooling chip. This utility model, a continuously adjustable variable inductor, uses the combined action of the cooling fan and the semiconductor cooling chip to dissipate heat from the surface of the magnetic core, avoiding excessively high surface temperature of the magnetic core that would increase magnetic resistance and thus reduce inductance, thereby improving heat dissipation efficiency and solving the problems of reduced inductance and inconvenience in adjusting the inductance of the inductor.

[0005] While the aforementioned technical solutions offer the advantage of adjusting the inductance of the inductor, they still present some challenges in practical application. Firstly, the number of heat dissipation holes and heat sinks is limited, and their arrangement is unreasonable. Secondly, directly mounting a cooling fan from the bottom is problematic due to the fan's large size, making assembly difficult and consuming considerable space. Furthermore, bottom mounting reduces the fan's usable area, hindering its efficient heat dissipation. Therefore, developing an inductor with good heat dissipation and adjustable inductance is of significant practical importance. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable multilayer heat dissipation inductor includes an adjustable inductor body and a top cover disposed on the top of the adjustable inductor body. A perforated ventilation plate is fixedly installed on the bottom of the housing of the adjustable inductor body. A heat-conducting ring is fixedly installed on the outer surface of the housing in the middle of the adjustable inductor body.

A heat dissipation assembly for ventilation and heat dissipation is also provided on the adjustable inductor body.

[0011] Preferably, the height of the support leg is between 0.8cm and 1.5cm, and a support base is fixedly installed at the bottom of the support leg.

[0012] Preferably, the support base is fixedly installed on the top surface of the air outlet, and the top plate of the air outlet is provided with multiple air outlet holes;

[0018] Preferably, a fixing rod is fixedly installed between the air collecting pipe and the air inlet ring, and multiple screw fixing plates are fixedly installed on the annular side of the air inlet ring, and the screw fixing plates are fixedly installed on the external frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1.

The perforated ventilation plate facilitates airflow at the bottom, the heat-conducting ring and heat dissipation fins directly conduct heat, the heat dissipation holes accelerate air convection at the top, and the heat dissipation component guides the airflow generated by the fan in an orderly manner to the adjustable inductor body, achieving a highly efficient and sufficient heat dissipation effect and effectively avoiding heat accumulation that leads to a decline in inductor performance.

[0021] 2. This utility model changes the traditional bottom-blowing heat dissipation method by placing the fan inside the air inlet ring and connecting it to the air outlet through the air collection pipe, air inlet cover and ventilation pipe. It realizes flexible air guidance and diversion, which can not only effectively dissipate heat on the main body of the adjustable inductor, but also direct some air to other electronic devices.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: an adjustable multilayer heat dissipation inductor, including an adjustable inductor body 1 and a top cover 10 disposed on the top of the adjustable inductor body 1. A perforated ventilation plate 15 is fixedly installed at the bottom of the housing of the adjustable inductor body 1. The perforated ventilation plate 15 has a perforated plate structure. Two symmetrical support legs 13 are fixedly installed at the bottom of the housing of the adjustable inductor body 1, which enable ventilation operation of the perforated ventilation plate 15. In addition, the support legs 13 provide support, forming a ventilation space at the bottom of the adjustable inductor body 1. The perforated ventilation plate 15 facilitates air circulation, and the support legs 13 suspend the body, ensuring smooth airflow at the bottom, thereby achieving effective heat dissipation at the bottom of the inductor body, reducing the temperature at the bottom of the body and improving heat dissipation efficiency.

[0033] In this embodiment, a heat-conducting ring 12 is fixedly installed on the outer side of the middle shell of the adjustable inductor body 1. Multiple heat dissipation fins 121 arranged in a ring at equal intervals are fixedly installed on the heat-conducting ring 12. The inner ends of the heat dissipation fins 121 extend to the inner wall of the shell of the adjustable inductor body 1, which can quickly conduct the heat generated by the body. The heat dissipation fins 121 are arranged in a ring at equal intervals and the inner ends extend to the inner wall of the shell, which greatly increases the heat dissipation area and achieves the purpose of efficiently conducting the heat inside the body to the outside and dissipating it, thereby reducing the overall temperature of the body and ensuring the stable operation of the inductor.

[0034] Specifically, the top surface of the top cover 10 is provided with multiple heat dissipation holes 11 that are connected to the interior of the adjustable inductor body 1, so that the hot air inside the adjustable inductor body 1 can be discharged upward through the heat dissipation holes 11 to form air convection. Together with the mesh ventilation plate 15 at the bottom, the air inside the body can circulate vertically, thereby further improving the heat dissipation effect and preventing heat accumulation.

[0035] like Figure 2 and Figure 4 As shown, the adjustable inductor body 1 is also provided with a heat dissipation component 2 for ventilation and heat dissipation. The heat dissipation component 2 includes an air outlet 20 located at the bottom of the adjustable inductor body 1 and a fan 22 for air intake into the air outlet 20. The height of the support leg 13 is between 0.8cm and 1.5cm. A support base 14 is fixedly installed at the bottom end of the support leg 13. The support base 14 is fixedly installed on the top surface of the air outlet 20. Multiple air outlet holes 201 are provided on the top plate of the air outlet 20, so that air is blown out from the air outlet holes 201 and performs better heat dissipation on the adjustable inductor body 1.

[0036] like Figure 4 As shown, multiple fixed protrusions 202 arranged in a ring at equal intervals are fixedly installed on the annular side of the bottom cylinder of the air outlet duct 20. The fixed protrusions 202 can be detachably installed on the corresponding external frame by multiple fastening screws, which facilitates the fixed installation operation.

[0037] It is worth noting that the heat dissipation assembly 2 also includes an air inlet ring 21, with the fan 22 fixedly installed on the inner wall of the air inlet ring 21. The heat dissipation assembly 2 also includes an air collecting pipe 23 disposed at the air outlet end of the air inlet ring 21. An air inlet cover 24 is fixedly installed at the air outlet end of the air collecting pipe 23, and a ventilation pipe 25 is fixedly installed at the end of the air inlet cover 24. The ventilation pipe 25 is fixedly installed on the air outlet duct 20 and communicates with the interior of the air outlet duct 20. This allows some of the air blown out by the fan 22 to be delivered to the adjustable inductor body 1 for heat dissipation, while also allowing other air blown out by the fan 22 to flow to other electronic components for heat dissipation. This achieves reasonable distribution and efficient utilization of the air blown out by the fan 22, thereby improving the fan's heat dissipation utilization rate and meeting various heat dissipation needs.

[0038] It is worth noting that a fixing rod 231 is fixedly installed between the air collection duct 23 and the air inlet ring 21, which serves to fix and support the air inlet ring 21; multiple screw fixing plates 211 are fixedly installed on the annular side of the air inlet ring 21, and the screw fixing plates 211 are fixedly installed on the external frame by multiple fastening screws, which facilitates the fixing and installation operation.

[0039] When the adjustable multilayer heat dissipation inductor of this utility model is in use, part of the heat generated by the inductor is conducted to the heat dissipation fins 121 through the heat conduction ring 12, and the heat dissipation fins 121 are used to dissipate heat by contacting the air over a large area; another part of the hot air is discharged upward from the heat dissipation holes 11 of the top cover 10, while the bottom mesh ventilation plate 15 draws in cold air, forming air convection to assist in heat dissipation.

[0040] When the heat dissipation component 2 is working, the fan 22 starts running, and the air enters the air outlet 20 through the air collection pipe 23, the air inlet shroud 24 and the ventilation pipe 25, and is blown out from the air outlet 201 to provide directional heat dissipation for the adjustable inductor body 1; and part of the air blown out by the fan 22 can also be guided to other electronic components for heat dissipation through reasonable layout.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
