Description

Technical Field

[0001] This utility model relates to the field of differential mode inductor technology, and in particular to a differential mode inductor with good heat dissipation. Background Technology

[0002] A differential-mode inductor is an inductor used in power electronics and signal processing. It is mainly used to suppress electromagnetic interference and improve the differential-mode signal characteristics of circuits. It is commonly used in devices such as switching power supplies, filters, and transformers. It mainly consists of a magnetic core, windings, and pin terminals. It reduces the impact of ground noise by using the phase difference of the differential-mode signal, thereby improving the stability and performance of the system.

[0003] In order to improve the heat dissipation capacity of the magnetic core, existing differential mode inductors typically add a thermally conductive silicone pad and a thermally conductive base between the bottom of the magnetic core and the base, and increase the number of heat sinks or heat sink fins in the thermally conductive base to expand the overall heat dissipation area, so as to better guide airflow through the heat dissipation structure and remove more heat.

[0004] However, the differential mode inductor heat dissipation structure mentioned above has a large number of heat sinks layered on top of each other. During long-term use, dust easily accumulates on the surface of the heat sinks. On the one hand, since the heat sinks are fixed on the heat conduction base and the distance between two adjacent heat sinks is small, it is inconvenient to remove the dust on the heat sinks, which affects the heat dissipation efficiency of the differential mode inductor. Utility Model Content

[0005] To address the problems existing in the background technology, a differential mode inductor with good heat dissipation is proposed. The magnetic core is cooled by a heat sink and thermally conductive silicone. A heat sink component is provided on the outside of the heat sink. Multiple first and second fins are spaced apart using first and second strip plates, and fastening components are provided to limit their movement. This allows the heat sink component to be removed from the heat sink. Furthermore, the first and second strip plates separate the first and second fins, thereby increasing the clearance between the fins for cleaning, improving operational convenience, and ensuring effective heat dissipation for the core.

[0006] This utility model proposes a differential mode inductor with good heat dissipation, including...

[0007] The base plate has a heat sink cover, which is filled with thermally conductive silicone. A magnetic core is located on the top of the heat sink cover, and a coil is wound around the outside of the magnetic core.

[0008] A heat sink, disposed on both sides of the heat sink shroud, includes a first heat sink assembly and a second heat sink assembly, which are used to increase the heat dissipation area of ​​the heat sink shroud; and

[0009] A fastening assembly, mounted on the heat sink, is used to simultaneously limit the first and second heat sink groups on both sides of the heat sink.

[0010] Preferably, the first heat dissipation group includes a first strip plate, and a plurality of first fins are linearly and equidistantly arranged on one side of the first strip plate, with the sides of the plurality of first fins abutting against the sides of the heat dissipation shroud.

[0011] Preferably, the second heat dissipation group includes a second strip plate, which is vertically offset from the first strip plate. Multiple sets of second fins are linearly and equidistantly arranged on one side of the second strip plate. The sides of the multiple sets of second fins abut against the sides of the heat dissipation shroud, and the multiple sets of second fins are horizontally offset from the multiple sets of first fins.

[0012] Preferably, the fastening assembly includes a guide frame, a movable plate, a clamp, and a manual drive component. Two sets of guide frames are symmetrically arranged at both ends of the heat sink. Two sets of movable plates are slidably arranged between the two sets of guide frames. A manual drive component for moving the two sets of movable plates is arranged between them. A clamp is connected between the two sets of movable plates on the same side. The clamp is U-shaped, and its vertical section abuts against the side of the heat sink.

[0013] Preferably, the manual drive component includes a two-way lead screw, lugs, and a drive rod. The two-way lead screw is laterally rotatable inside the heat sink, and both ends of the lead screw are threaded through the heat sink and connected to lugs. The two sides of the lugs are rotatably connected to the corresponding two moving plates, and the end of the two-way lead screw is connected to a handwheel.

[0014] Preferably, a horizontal tube for covering the bidirectional lead screw is also horizontally arranged inside the heat sink.

[0015] Through the above technical solution, namely the differential mode inductor disclosed in this utility model, the magnetic core is dissipated through a heat sink and thermally conductive silicone. A heat sink component assembled from a first heat sink group and a second heat sink group is provided on the outside of the heat sink. Multiple first fins and second fins are spaced apart by a first strip plate and a second strip plate. At the same time, fastening components that limit the position of the two are provided. With the cooperation of a guide frame, a moving plate, a clamp, and a manual drive component, the heat sink component can be removed from the heat sink. At the same time, the first fins and second fins can be separated by the first strip plate and the second strip plate, thereby increasing the cleaning gap between the fins, improving the convenience of operation, and ensuring the subsequent heat dissipation effect on the iron core.

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] Example 1

[0024] like Figures 1-4 As shown, the present invention proposes a differential mode inductor with good heat dissipation effect, including a base plate 1, heat sink components and fastening components. A heat sink 2 is provided on the base plate 1, and the heat sink 2 is filled with thermally conductive silicone. A magnetic core 3 is provided on the top of the heat sink 2, and a coil 4 is wound around the outside of the magnetic core 3. Heat sink components are provided on both sides of the heat sink 2, and the heat sink components include a first heat sink group and a second heat sink group, which are used to expand the heat dissipation area of ​​the heat sink 2. A fastening component is provided on the heat sink 2 for synchronously limiting the first heat sink group and the second heat sink group.

[0025] Among them, the first fin 6, the second fin 8 and the heat sink 2 are all made of copper, which has a good heat conduction and heat dissipation effect.

[0026] like Figure 3 As shown, the first heat dissipation group includes a first strip plate 5, and multiple sets of first fins 6 are linearly and equidistantly arranged on one side of the first strip plate 5. The sides of the multiple sets of first fins 6 abut against the sides of the heat dissipation shroud 2.

[0027] like Figure 3 As shown, the second heat dissipation group includes a second strip plate 7, which is vertically offset from the first strip plate 5. Multiple sets of second fins 8 are linearly and equidistantly arranged on one side of the second strip plate 7. The sides of the multiple sets of second fins 8 abut against the sides of the heat dissipation shroud 2, and the multiple sets of second fins 8 are horizontally offset from the multiple sets of first fins 6.

[0028] The first fin 6 and the second fin 8 are staggered on both sides of the heat sink 2 by the first strip plate 5 and the second strip plate 7, which ensures the overall arrangement density and maximizes the heat dissipation area. When it is necessary to remove dust from the first fin 6 and the second fin 8, they can be separated by the first strip plate 5 and the second strip plate 7, which expands the processing space and improves the convenience of operation.

[0029] Example 2

[0030] like Figures 1-4 As shown, this utility model proposes a differential mode inductor with good heat dissipation. Based on the above embodiments, this embodiment also details the specific components of the fastening assembly and its specific limiting method for the heat sink.

[0031] like Figure 1 and Figure 4 As shown, the fastening assembly includes a guide frame 9, a movable plate 10, a clamp 11, and a manual drive component. Two sets of guide frames 9 are symmetrically arranged at both ends of the heat sink 2. Two sets of movable plates 10 are slidably arranged between the two sets of guide frames 9. A manual drive component for moving the two sets of movable plates 10 is arranged between them. A clamp 11 is connected between the two sets of movable plates 10 located on the same side. The clamp 11 is set in the shape of a chamfer, and its vertical section is limited and abutted against the side of the heat sink.

[0032] The movable plate 10 can be moved horizontally along the guide frame 9 by a manual drive component. During the movement, the clamp 11 moves synchronously, thereby tightly limiting the heat sink component to the side of the heat sink 2.

[0033] like Figure 4 As shown, the manual drive component includes a two-way lead screw 12, lugs 13, and a drive rod 14. The two-way lead screw 12 is laterally rotatably disposed inside the heat sink 2, and both ends of the lead screw 12 are threaded through the heat sink 2 and connected to lugs 13. The two sides of the lugs 13 are respectively rotatably connected to the corresponding two moving plates 10 and the drive rod 14. The end of the two-way lead screw 12 is connected to a handwheel 15.

[0034] The bidirectional lead screw 12 and the two lugs 13 are connected by opposite threads, meaning that when the bidirectional lead screw 12 is rotated by the handwheel 15, the two lugs 13 will move synchronously in opposite directions.

[0035] like Figure 2 As shown, a horizontal tube 16 is also horizontally arranged inside the heat sink 2 to cover the bidirectional lead screw 12. The bidirectional lead screw 12 is protected by the horizontal tube 16 to prevent it from contacting the thermally conductive silicone and affecting the subsequent operation.

[0036] When it is necessary to remove the heat sink from the heat sink cover 2 to remove the dust on it, the handwheel 15 is turned in the opposite direction. The handwheel 15 drives the double-acting screw 12 to rotate. During the rotation of the double-acting screw 12, the two lugs 13 move towards each other. During the movement, they drive one end of the drive rod 14 to move. The other end of the drive rod 14 adaptively changes its angle and drives the moving plates 10 on both sides of the double-acting screw 12 to move to both sides. During the movement of the moving plates 10, the clamps 11 move to both sides, thereby loosening the fastening of the heat sink.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
