Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer heat sink with high heat dissipation efficiency. Background Technology

[0002] Heat sink fins are a common heat dissipation method for transformers. They can quickly transfer the heat generated by the transformer to the outside through heat conduction. Although heat sink fins facilitate heat dissipation for transformers, they still have shortcomings in actual use. When a transformer is used for a long time, an electromagnetic field is generated around it, which causes dust to be attracted to the heat sink fins. Since the heat sink fins mainly play the role of enhancing heat dissipation, if dust is attached, it will easily affect its heat dissipation effect, making it difficult for the heat inside the transformer to dissipate. Therefore, a high heat dissipation efficiency transformer heat sink is proposed to self-clean the heat sink fins and maintain their heat dissipation efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a transformer heat sink with high heat dissipation efficiency, solving the problem of reduced heat dissipation efficiency caused by dust accumulation on the heat sink fins.

A limiting insert, matching the narrow opening of the T-slot, is slidably connected inside the limiting sleeve. A return spring is fixedly connected between the limiting insert and the limiting sleeve. Two abutment plates, matching the pressing plate, are fixedly connected between the two sides of the inner cavity of the mounting shell, and two abutment plates are symmetrically arranged above and below each other.

[0007] Preferably, the multi-angle blower mechanism includes a U-shaped frame, and two U-shaped frames are provided, with the two U-shaped frames respectively fixedly installed on both sides of the top of the mounting shell. Short rods are rotatably installed on the front and rear sides of the inner cavity of the U-shaped frame. An electric fan is fixedly connected between the two short rods.

[0012] Beneficial effects This invention provides a transformer heat sink with high heat dissipation efficiency. Compared with existing technologies, it has the following advantages: (1) The high heat dissipation efficiency transformer heat sink, by setting a dust removal mechanism, an angle adjustment mechanism and a multi-angle blower mechanism on the surface of the mounting shell, enables the device to accelerate the airflow around the heat sink fins through the above-mentioned coordinated action, thereby improving the heat dissipation effect and strengthening the heat dissipation. At the same time, it simultaneously performs a reciprocating single-pass scraping to remove dust from the heat sink fins, ensuring that the heat sink fins are not affected by dust accumulation, which would lead to a significant reduction in heat dissipation efficiency. Simultaneously, it adjusts the tilt of the reciprocating scraper that is about to move from bottom to top, which ensures that the scraper surface automatically removes dust and avoids the problem that the dust will re-contact the heat sink fins when the scraper moves from bottom to top.

[0013] (2) The high heat dissipation efficiency transformer heat sink, by rotating the roller at the end of the extrusion plate, can improve the smoothness of the extrusion displacement between the extrusion plate and the inclined groove when the extrusion plate and the inclined groove are extruded and matched.

[0014] (3) The high heat dissipation efficiency transformer heat sink is designed to limit the extrusion plate by setting a guide groove and a guide slider that are compatible with the extrusion plate on the inner wall of the vertical slot opening.

[0015] (4) The high heat dissipation efficiency transformer heat sink has guide grooves on both sides of the mounting shell that are matched with the horizontal plate, so that the threaded sleeve can slide and limit the horizontal plate through the guide groove, making the threaded sleeve move more smoothly.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Please see Figures 1-9 The present invention provides a technical solution: a transformer heat sink with high heat dissipation efficiency, including a mounting shell 1 installed on the surface of the transformer, and a plurality of heat dissipation fins 2 are installed in an equidistant array through mounting openings on the rear side of the inner cavity of the mounting shell 1.

[0020] In a preferred embodiment, to facilitate cleaning of dust accumulation on the surface of the heat dissipation fins 2, a dust removal mechanism 3 is provided on the surface of the mounting shell 1. The dust removal mechanism 3 includes a drive motor 301, which is fixedly mounted on one side of the mounting shell 1. The output shaft of the drive motor 301 is fixedly connected to a reciprocating screw 302 via a coupling. The surface of the reciprocating screw 302 is rotatably connected to the side of the mounting shell 1 via a bearing. A threaded sleeve 303 is threadedly connected to the surface of the reciprocating screw 302. A horizontal plate 304 is fixedly connected to one side of the threaded sleeve 303. Several mounting frames 305 are fixedly connected in an equidistant array on the rear side of the horizontal plate 304. A rotating rod 306 is rotatably mounted inside the mounting frame 305, and one end of the rotating rod 306 extends to the rear side of the mounting frame 305. A scraper 307 is fixedly connected to the surface of the rotating rod 306. Guide grooves 12 that slide and adapt to the horizontal plate 304 are provided on both sides of the mounting shell 1.

[0021] In a preferred embodiment, to facilitate flexible adjustment of the single-pass scraping angle of the scraper 307, the dust removal mechanism 3 is internally equipped with an angle adjustment mechanism 4. The angle adjustment mechanism 4 includes a first gear 401, which is fixedly mounted on the surface of the rotating rod 306. The mounting frame 305 is internally connected to a first toothed plate 402 that meshes with the first gear 401. T-slots 403 are provided at the top and bottom of the inner cavity of the first toothed plate 402. A T-block 404 is slidably mounted inside the T-slots 403, and an inclined groove 40 is provided inside the T-block 404. 5. The first toothed plate 402 is slidably provided with an extrusion plate 406 that is used in conjunction with the inclined groove 405. The top and bottom of one side of the inner cavity of the mounting frame 305 are fixedly connected with a limiting sleeve 407. The limiting sleeve 407 is slidably connected with a limiting block 408 that is used in conjunction with the narrow opening of the T-slot 403. A return spring 409 is fixedly connected between the limiting block 408 and the limiting sleeve 407. A baffle plate 410 that is used in conjunction with the extrusion plate 406 is fixedly connected between the two sides of the inner cavity of the mounting shell 1. Two baffle plates 410 are symmetrically arranged on the upper and lower sides. The top and bottom of the first toothed plate 402 are provided with vertical slot openings 6 that communicate with the T-slot 403. The inner wall of the vertical slot opening 6 is provided with a guide slide groove 7. The guide slide groove 7 is slidably connected to the inside of the guide slide groove 7, and the guide slide groove 8 is fixedly connected to the side of the extrusion plate 406. The end of the extrusion plate 406 is provided with a roller 9 through an installation groove.

[0022] In a preferred embodiment, to facilitate the accelerated airflow around the heat dissipation fins 2, a multi-angle blower mechanism 5 is provided on the top of the mounting shell 1. The multi-angle blower mechanism 5 includes a U-shaped frame 501, and two U-shaped frames 501 are provided. The two U-shaped frames 501 are respectively fixedly provided on both sides of the top of the mounting shell 1. Short rods 502 are rotatably provided on the front and rear sides of the inner cavity of the U-shaped frame 501. An electric fan 503 is fixedly connected between the two short rods 502. One end of the front short rod 502 extends to the outside of the U-shaped frame 501. A second gear 504 is fixedly connected to the surface of the front short rod 502. A cam 505 is fixedly connected to the surface of the reciprocating screw 302. A second toothed plate 506 that meshes with the second gear 504 is slidably provided on the top of the mounting shell 1. A hollow strip frame 507 that matches the cam 505 is fixedly connected to one side of the second toothed plate 506. The front side of the mounting shell 1 is provided with several limiting grooves 10 at equal intervals. The limiting grooves 10 are slidably connected to the limiting sliders 11, and the limiting sliders 11 are fixedly connected to the front side of the second tooth plate 506 through the bracket.

[0023] During heat dissipation: the electric fan 503 and drive motor 301 are started. When the electric fan 503 starts, it accelerates the airflow around several heat dissipation fins 2. When the drive motor 301 starts, it drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the cam 505 to reciprocate and laterally squeeze the hollow frame 507, causing the hollow frame 507 to drive the second tooth plate 506 to reciprocate and mesh with the second gear 504. The second gear 504 reciprocates and adjusts the airflow direction of the electric fan 503 through the short rod 502. When the reciprocating screw 302 rotates, the threaded sleeve 303 on the surface of the reciprocating screw 302 will drive the horizontal plate 304, mounting frame 305, rotating rod 306 and scraper 307 to move downwards. The scraper 307 descends and cleans the dust attached to the side of the guide groove 7. As the mounting frame 305 descends, the pressing plate 406 at the bottom of the mounting frame 305 will pre-press into contact with the bottom stop plate 410, causing the pressing plate 406 to press and push the T-block 404 through the inclined surface of the inclined groove 405. The force on the T-block 404 will push the limiting insert 408 out of the T-groove 40. Outside of 3, as the T-block 404 fills the narrow opening of the T-slot 403, the extrusion plate 406 is subjected to force and will drive the first toothed plate 402 to rise through the T-block 404 until the top limiting insert 408 engages with the T-slot 403. When the first toothed plate 402 rises, it will mesh with the first toothed plate 402, causing the rotating rod 306 to drive the scraper 307 to tilt. As the scraper 307 adjusts its tilt, the corresponding threaded sleeve 303 will change from the downward threaded path of the reciprocating screw 302 to the upward path, thereby driving the tilted scraper 307 to rise. When the threaded sleeve 303 rises to the limit of the rising path of the reciprocating screw 302, the corresponding scraper 307 is squeezed and cooperated by the top pressing plate 406, the inclined groove 405, the T-block 404 and the stop plate 410, so that the scraper 307 forms a balanced state before descending.
