Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and in particular to an inductor with easy heat dissipation. Background Technology

[0002] An inductor is a common electronic component that works on the principle of electromagnetic induction. Inductors have the characteristic of impeding changes in current; the faster the current changes, the stronger the impeding effect. This characteristic enables them to perform a variety of functions. For example, in a filter circuit, it can block high-frequency currents while allowing low-frequency currents to pass through smoothly, thereby purifying the current.

[0003] Existing technologies often have the following drawbacks: When current flows through the inductor coil during actual use, power loss occurs due to the resistance of the wires, which is converted into heat. This thermal effect is more pronounced, especially under high current or high frequency current conditions. If the heat cannot be dissipated in time, the inductor temperature will continue to rise. Excessive temperature will negatively affect the inductor's performance, reduce its stability, increase its losses, and may also accelerate the aging of the inductor's internal materials, shortening its service life.

[0004] Therefore, this invention provides an inductor that is easy to dissipate heat. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is inconvenient to dissipate heat from inductors, and to propose an inductor that is easy to dissipate heat.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inductor with easy heat dissipation, comprising an inductor body, two leads fixedly connected to the surface of the inductor body, a metal shell covering the outer side of the inductor body, two reserved holes on the lower surface of the metal shell, the size of the reserved holes being adapted to the size of the leads, a plurality of heat sinks being uniformly fixedly connected to the outer side of the metal shell, and a layer of silicone grease being bonded to the inner side of the metal shell.

[0007] The effect achieved by the above components is that by setting the above structure, the effective heat dissipation of the inductor is facilitated, which to a certain extent improves the service life of the inductor and maximizes the service life of the inductor.

[0008] Preferably, a row of heat dissipation holes is uniformly formed on the surface of the heat sink.

[0009] The effect achieved by the above components is that the heat dissipation holes on the surface of the heat sink promote air circulation and accelerate the dissipation of heat into the surrounding environment.

[0010] Preferably, the outer surface of the inductor body is wrapped with graphite paper, which is located between the silicone grease layer and the inductor body.

[0011] The effect achieved by the above components is as follows: the graphite paper wrapped around the outer surface of the inductor plays a key role. The good thermal conductivity of the graphite paper can quickly absorb the heat generated by the inductor and conduct the heat away.

[0012] Preferably, a first adhesive paper is bonded to the inner side of the graphite paper, and a second adhesive paper is bonded to the outer side of the graphite paper.

[0013] The effect achieved by the above components is that the first and second adhesive tapes between the graphite paper and the inductor body ensure a tight fit between the graphite paper and the inductor body, thereby improving the stability of the graphite paper when it is wound around the inductor body.

[0014] Preferably, the inner side of the metal shell is threaded with a cap.

[0015] The effect achieved by the above components is that the cap with the threaded connection on the inside of the metal shell can, on the one hand, provide a certain degree of protection for the inductor body and prevent foreign objects from entering and affecting the performance of the inductor.

[0016] Preferably, a sealing gasket is glued to the side wall of the cap, and the sealing gasket is located between the metal shell and the cap.

[0017] The effect achieved by the above components is that the sealing gasket bonded to the side wall of the cap can enhance the sealing performance of the metal shell, preventing dust, moisture, etc. from entering and affecting the normal operation of the inductor.

[0018] Preferably, a torsion block is fixedly connected to the upper surface of the cap, and the torsion block has a cross structure.

[0019] The effect achieved by the above components is that the "+" shaped twist block on the upper surface of the cap makes it easy for operators to rotate the cap, thus enabling the cap to be installed and removed.

[0020] In summary:

[0021] In this invention, when the inductor is connected to the circuit and current flows through the coil of the inductor body, heat is generated due to the resistance of the wire. At this time, the graphite paper wrapped around the outer surface of the inductor body plays a key role. The good thermal conductivity of the graphite paper can quickly absorb the heat generated by the inductor body and conduct the heat away. By setting the above structure, the effective heat dissipation of the inductor is facilitated, which improves the service life of the inductor to a certain extent and maximizes the service life of the inductor.

[0028] Reference Figure 1-5 As shown, this utility model provides a technical solution: an inductor with easy heat dissipation, including an inductor body 1, and two leads 2 are fixedly connected to the surface of the inductor body 1.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] In this implementation scheme: a metal shell 3 is fitted around the outer side of the inductor body 1. Two pre-drilled holes 7 are formed on the lower surface of the metal shell 3, the size of which matches the size of the lead wire 2. Several heat sinks 4 are uniformly fixedly connected to the outer side of the metal shell 3, and a silicone grease layer 10 is bonded to the inner side of the metal shell 3. This structure facilitates effective heat dissipation of the inductor, improving its lifespan to a certain extent. A row of heat dissipation holes 5 is uniformly formed on the surface of the heat sink 4. These holes promote airflow and accelerate heat dissipation into the surrounding environment. Graphite paper 9 is wound around the outer surface of the inductor body 1, located between the silicone grease layer 10 and the inductor body 1. The graphite paper 9 plays a crucial role; its excellent thermal conductivity allows it to quickly absorb the heat generated by the inductor body 1 and conduct it away. A first adhesive tape 11 is bonded to the inner side of the graphite paper 9, and a second adhesive tape 12 is bonded to the outer side of the graphite paper 9. The first adhesive tape 11 and the second adhesive tape 12 between the graphite paper 9 and the inductor body 1 ensure that the graphite paper 9 and the inductor body 1 are tightly bonded, thereby improving the stability of the graphite paper 9 when it is wound around the inductor body 1.

[0031] Specifically, a cap 6 is threaded onto the inner side of the metal casing 3. The cap 6, threaded onto the inner side of the metal casing 3, provides some protection for the inductor body 1, preventing external foreign objects from entering and affecting the inductor's performance. A sealing gasket 8 is glued to the side wall of the cap 6, located between the metal casing 3 and the cap 6. The sealing gasket 8 enhances the sealing performance of the metal casing 3, preventing dust, moisture, etc., from entering and affecting the normal operation of the inductor. A toggle block 13, with a cross-shaped structure, is fixedly connected to the upper surface of the cap 6. The cross-shaped toggle block 13 on the upper surface of the cap 6 facilitates the operator's rotation of the cap 6, enabling the installation and removal of the cap 6.

[0032] Working principle: When the inductor is connected to the circuit, and current flows through the coil of the inductor body 1, heat is generated due to the resistance of the wires. At this time, the graphite paper 9 wound on the outer surface of the inductor body 1 plays a crucial role. The excellent thermal conductivity of the graphite paper 9 allows it to quickly absorb the heat generated by the inductor body 1 and conduct it away. The first adhesive paper 11 and the second adhesive paper 12 between the graphite paper 9 and the inductor body 1 ensure a tight fit between the graphite paper 9 and the inductor body 1, improving the stability of the graphite paper 9 when wound on the inductor body 1. The heat conducted by the graphite paper 9 is transferred to the silicone grease layer 10. The silicone grease has good thermal conductivity and filling properties, which can fill the tiny gaps between the graphite paper 9 and the metal shell 3, improving the heat transfer efficiency and quickly transferring heat to the metal shell 3. The metal shell 3 serves as the main heat dissipation component. The evenly distributed heat sinks 4 on the outer side greatly increase the heat dissipation area. The heat dissipation holes 5 on the surface of the heat sinks 4 promote air circulation and accelerate the dissipation of heat into the surrounding environment, achieving efficient heat dissipation. The cap 6 with the threaded connection on the inner side of the metal shell 3 can, on the one hand, protect the inductor body 1 to a certain extent and prevent foreign objects from entering and affecting the performance of the inductor. On the other hand, the sealing gasket 8 glued to the side wall of the cap 6 can enhance the sealing of the metal shell 3 and prevent dust, moisture and other substances from entering and affecting the normal operation of the inductor. The "+" structure toggle block 13 on the upper surface of the cap 6 makes it easy for operators to rotate the cap 6 to install and remove the cap 6. By setting the above structure, the effective heat dissipation of the inductor is facilitated, which to a certain extent improves the service life of the inductor and maximizes the service life of the inductor.
