Description

Technical Field

[0001] This utility model relates to the field of transformer radiator technology, and in particular to a transformer radiator heat sink with optimized structure. Background Technology

[0002] Transformer radiator fins are crucial components of transformers, primarily used to reduce the transformer's temperature during operation and prevent heat buildup that can lead to aging of the internal insulation materials. Transformers generate heat during operation, which can accumulate and, if not dissipated promptly, accelerate the aging of the internal insulation, affecting the transformer's stability and lifespan. Therefore, the design and performance of transformer radiator fins are critical to the stable operation of the transformer.

[0003] An existing transformer radiator with optimized structure makes it inconvenient for workers to adjust the distance between multiple radiators according to the transformer's usage when working with cooling equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a transformer heat sink with optimized structure.

[0005] This utility model is achieved using the following technical solution: a transformer radiator heat sink with optimized structure, including a fixed sleeve, a fixed base plate fixedly connected to the rear end of the fixed sleeve, a positioning screw threadedly connected to the inside of the fixed sleeve, a push ring fixedly connected to the surface of the positioning screw, a limit groove formed inside the fixed sleeve, a limit plate threadedly connected to the surface of the positioning screw, a spring fixedly connected to the rear end of the limit plate, a limit ring fixedly connected to the rear end of the spring, a heat sink slidably connected to the surface of the fixed sleeve, push rings fixedly connected to the front and rear ends of the heat sink, and grooves formed at the front and rear ends of the heat sink.

[0006] As a further improvement to the above solution, the number of the fixing sleeve and the fixing base plate is set to two, and the two fixing sleeves and the fixing base plate are symmetrically distributed vertically around the heat sink.

[0007] With the above technical solution, when installing the heat sink, the retaining ring can be rotated and pushed to make it contact the surface of the heat sink and apply appropriate pressure according to the specific size and installation requirements of the heat sink, thereby firmly fixing the heat sink in the fixing sleeve and preventing the heat sink from shifting during use.

[0008] As a further improvement to the above solution, the number of push retaining rings is set to several, and several push retaining rings are threadedly connected to the inner wall of the fixed sleeve.

[0009] As a further improvement to the above solution, the number of the limiting plates and springs is set to several, and the several limiting plates and springs are symmetrically distributed vertically around the heat sink.

[0010] With the above technical solution, several limiting plates and springs are symmetrically distributed above and below the heat sink. The springs can play a buffering role. When the heat sink is subjected to external impact or shakes due to transformer vibration, the springs can absorb and buffer this energy, protecting the heat sink and other related components from damage.

[0011] As a further improvement to the above solution, the limiting ring is fixedly connected to the front side of the heat sink, and the spring is fixedly connected to the front side of the heat sink.

[0012] As a further improvement to the above solution, the limiting plate is located at the rear end of the heat sink, and the number of the limiting slots is set to several, with the several limiting slots symmetrically distributed vertically around the heat sink.

[0013] As a further improvement to the above scheme, the number of the driving rings is set to several, and each pair is a group, with the several driving rings symmetrically distributed back and forth around the heat sink.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, by rotating the positioning screw inside the fixed sleeve and the pushing ring on the surface, moves and extends back and forth within the fixed sleeve. This causes the limiting plate on the surface of the positioning screw to move in the limiting groove and inside the fixed sleeve in conjunction with the positioning screw and the pushing ring on the surface to extend to the rear end position. This causes the limiting plate to be subjected to a backward compressive force, which in turn causes the spring and the limiting ring to extend the heat sink and the tile groove back and forth on the surface of the fixed sleeve.

[0016] This utility model uses a limiting ring to fix the front of the heat sink, which works in conjunction with other components to provide positioning. It serves as a positioning reference point for the front end of the heat sink, ensuring the accurate installation position of the heat sink within the fixing sleeve. During installation, the installer can judge whether the heat sink is installed correctly based on the relative position of the limiting ring and the front end of the fixing sleeve, ensuring the correct installation depth of the heat sink within the fixing sleeve. Its fixed connection to the front end of the heat sink allows the front end to maintain good shape and stability when subjected to various forces, preventing deformation or damage to the front end, thereby indirectly ensuring the heat dissipation performance of the heat sink.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figures 1-5 This embodiment of a transformer radiator heat sink with optimized structure includes a fixed sleeve 1. A fixed base plate 2 is fixedly connected to the rear end of the fixed sleeve 1. A positioning screw 3 is threadedly connected inside the fixed sleeve 1. A push ring 11 is fixedly connected to the surface of the positioning screw 3. A limit groove 5 is formed inside the fixed sleeve 1. A limit plate 6 is threadedly connected to the surface of the positioning screw 3. A spring 7 is fixedly connected to the rear end of the limit plate 6. A limit ring 8 is fixedly connected to the rear end of the spring 7. A heat sink 9 is slidably connected to the surface of the fixed sleeve 1. The front and rear ends of the heat sink 9 are fixedly connected to... There is a push ring 11. The heat sink 9 has grooves 10 at both ends. When the positioning screw 3 inside the fixed sleeve 1 and the push ring 4 on the surface move and extend in the interior of the fixed sleeve 1, the limiting plate 6 on the surface of the positioning screw 3 can be driven to extend in the rear end position when the positioning screw 3 drives the push ring 4 in the interior of the fixed sleeve 1 in conjunction with the limiting groove 5. This causes the limiting plate 6 to be subjected to a backward squeezing force, which drives the spring 7 and the limiting ring 8 to extend the heat sink 9 and the groove 10 in the interior of the fixed sleeve 1.

[0025] The number of fixed sleeve 1 and fixed base plate 2 is set to two, and the two fixed sleeve 1 and fixed base plate 2 are symmetrically distributed vertically around the heat sink 9.

[0026] When installing the heat sink 9, the push ring 11 can be rotated according to the specific size and installation requirements of the heat sink 9 to make it contact the surface of the heat sink 9 and apply appropriate pressure, thereby firmly fixing the heat sink 9 in the fixing sleeve 1 and preventing the heat sink 9 from shifting during use.

[0027] The number of push rings 11 is set to several, and several push rings 11 are threadedly connected to the inner wall of the fixed sleeve 1.

[0028] The number of limiting plates 6 and springs 7 is set to several, and the several limiting plates 6 and springs 7 are symmetrically distributed vertically around the heat sink 9.

[0029] Several limiting plates 6 and springs 7 are symmetrically distributed around the heat sink 9. The springs 7 can act as a buffer. When the heat sink 9 is subjected to external impact or shakes due to transformer vibration, the springs 7 can absorb and buffer this energy, protecting the heat sink 9 and other related components from damage.

[0030] The limiting ring 8 is fixedly connected to the front of the heat sink 9, and the spring 7 is fixedly connected to the front of the heat sink 9.

[0031] The limiting plate 6 is located at the rear end of the heat sink 9. The number of limiting slots 5 is set to several, and the several limiting slots 5 are symmetrically distributed vertically around the heat sink 9. They are fixedly connected to the front of the heat sink 9 by setting a limiting ring 8, which works with other components to play a positioning role. It can serve as a positioning reference point for the front end of the heat sink 9, ensuring that the heat sink 9 is accurately installed in the fixed sleeve 1. During the installation process, the installer can judge whether the heat sink 9 is installed in place based on the relative position of the limiting ring 8 and the front end of the fixed sleeve 1, ensuring the correct installation depth of the heat sink 9 in the fixed sleeve 1. It is fixedly connected to the front end of the heat sink 9, so that the front end of the heat sink 9 can maintain a good shape and stability when subjected to various forces, preventing the front end from being deformed or damaged, thereby indirectly ensuring the heat dissipation performance of the heat sink 9.

[0032] The number of push rings 11 is set to several, and each pair is a group of several push rings 11 symmetrically distributed around the heat sink 9.

[0033] The implementation principle of the optimized transformer radiator heat sink in this embodiment is as follows: When the positioning screw 3 inside the fixed sleeve 1 and the pushing ring 4 on the surface move and extend back and forth inside the fixed sleeve 1, the limiting plate 6 on the surface of the positioning screw 3 can be driven to extend the rear end position of the pushing ring 4 inside the limiting groove 5 and the fixed sleeve 1, so that the limiting plate 6 is subjected to a backward compressive force, which drives the spring 7 and the limiting ring 8 to extend the heat sink 9 and the groove 10 on the surface of the fixed sleeve 1. The limiting ring 8 is used to fix the heat sink 9 and the groove 10 in a back and forth position. The front of the heat sink 9, in conjunction with other components, serves as a positioning reference point for the front end of the heat sink 9, ensuring the accurate installation position of the heat sink 9 within the fixing sleeve 1. During installation, the installer can determine whether the heat sink 9 is installed correctly based on the relative position of the limiting ring 8 and the front end of the fixing sleeve 1, ensuring the correct installation depth of the heat sink 9 within the fixing sleeve 1. Its fixed connection to the front end of the heat sink 9 allows the front end to maintain good shape and stability when subjected to various forces, preventing deformation or damage to the front end, thereby indirectly ensuring the heat dissipation performance of the heat sink 9.
