It is typically made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating. The core and the coils wound around it form a complete electromagnetic induction system. The power transmitted by a power transformer depends on the material and cross-sectional area of ​​the core. Transformers are widely used in industry, agriculture, transportation, urban communities, and are also widely used in charging stations for new energy vehicles.

[0003] However, the transformer cores currently on the market need to be fixed after the silicon steel sheets are stacked before the coils are installed. But the stacked cores have many layers, and the silicon steel sheets are prone to misalignment during coil installation, which leads to errors and a decrease in transformer performance. Utility Model Content

[0014] 1. An alignment and fixing assembly is provided. Rotating the compression nut compresses the compression spring, which in turn compresses the movable clamping plate, aligning the top and bottom ends of the laminated iron core. Rotating the rotating block in the middle of the tie rod sequentially rotates the tie rod, pulling the internally threaded tubes at both ends closer together, which in turn pulls the fixing clamping plates closer together. The compression nut is adjusted as needed to ensure the final alignment of the mating hole and the heat dissipation hole. During this process, the movable clamping plate continues to compress the top and bottom ends of the laminated iron core, completing the fixing while aligning the top and bottom ends of the laminated iron core. This facilitates fixing while ensuring the flatness of the laminated iron core ends, resulting in better assembly.

The heat pipes are embedded in the insulated heat pipes in a position that does not obstruct the wiring. Then, the connecting screw at the end of the mounting ring is rotated and inserted into the connecting nail hole for installation and fixation. Through the high thermal conductivity of the heat pipes, the heat dissipated by the laminated iron core during operation can be transferred to the heat dissipation fins for heat dissipation, effectively reducing the internal temperature of the laminated iron core and preventing it from overheating and causing safety problems.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1-4 As shown, this utility model provides a transformer core technical solution for new energy, including a laminated core 1. An alignment and fixing assembly 2 is installed on the outside of the laminated core 1. The alignment and fixing assembly 2 includes a fixing clamp 201, a movable clamp 202, a clamping adjustment hole 203, a limiting screw 204, a compression nut 205, a compression spring 206, a support base rod 207, a compression screw 208, an internal threaded tube 209, a pull screw 210, and a rotating block 211.

[0027] Fixed clamping plates 201 are installed on both sides of the top and bottom ends of the laminated iron core 1. Movable clamping plates 202 are installed on both sides of the two fixed clamping plates 201 at the same height. Clamping adjustment holes 203 are provided at both ends of the movable clamping plates 202 corresponding to the fixed clamping plates 201. A limiting screw 204 is welded inside the clamping adjustment hole 203 of the fixed clamping plate 201. The clamping adjustment hole 203 is an elongated hole with rounded corners at both ends. The diameter of the limiting screw 204 is equal to the width of the clamping adjustment hole 203, facilitating the sliding of the limiting screw 204 within the clamping adjustment hole 203. One end of the limiting screw 204 is threadedly connected to a compression nut 205. The limiting screw 204 is positioned between the compression nut 205 and the movable clamping plate. A compression spring 206 is sleeved between 202. The ends of the two fixed clamping plates 201 at the bottom are connected to the support rod 207 by bolts. Both ends of the movable clamping plate 202 are connected to the compression screw 208 through screw holes. The ends of the two fixed clamping plates 201 on the same side are welded with internal threaded tubes 209. The two opposing internal threaded tubes 209 are respectively connected to the two ends of the pull screw 210 by threads. A rotating block 211 is fixedly sleeved in the middle of the pull screw 210. The threads at both ends of the pull screw 210 turn in opposite directions. The rotating block 211 is a hexagonal prism with a round hole in the middle, which makes it convenient to turn the rotating block 211 to drive the pull screw 210 to rotate while adjusting the distance between the internal threaded tubes 209 at both ends.

[0028] The fixed clamp 201 is equipped with an auxiliary heat dissipation component 3, which includes a docking hole 301, a heat dissipation hole 302, an insulating heat conduction pipe 303, an isolation plate 304, a heat pipe 305, a heat dissipation fin 306, a mounting ring 307, a connecting screw 308, and a connecting screw hole 309.

[0029] The fixing clamp 201 has evenly spaced docking holes 301 in the middle. The laminated iron core 1 has heat dissipation holes 302 corresponding to the docking holes 301. An insulating heat-conducting pipe 303 is embedded inside the heat dissipation hole 302. An isolation plate 304 is bonded to the middle of the insulating heat-conducting pipe 303. Heat pipes 305 are movably sleeved at both ends of the insulating heat-conducting pipe 303. Heat dissipation fins 306 are evenly fixedly sleeved at the ends of the heat pipes 305. An installation ring 307 is fixedly sleeved in the middle of the heat pipe 305. Connecting screws 308 are symmetrically installed on one side of the installation ring 307 through screw holes. The fixing clamp 201 has connecting screw holes 309 corresponding to the connecting screws 308 to facilitate the installation and fixing of the heat pipes 305.

[0030] The working principle and usage process of this utility model are as follows: When installing the coil, the support base rod 207 is placed in the assembly position, and the fixed clamping plate 201 is symmetrically placed on the top surface of the support base rod 207. Then, the lower half of the laminated iron core 1 is placed on the top surface of the movable clamping plate 202 between the fixed clamping plates 201. After the coil is connected, the upper half of the laminated iron core 1 is installed. Then, the top fixed clamping plate 201 is installed. The pull screw 210 is threaded to the two ends of the corresponding internal threaded tube 209. Then, the clamping adjustment hole 203 of the movable clamping plate 202 is aligned with the limiting screw 204 and embedded. The compression spring 206 is sleeved on the limiting screw 204 on the top surface of the movable clamping plate 202, and the compression nut 205 is installed to complete the initial limiting operation.

[0031] After initial assembly, rotate the compression nut 205, which compresses the compression spring 206, which in turn compresses the movable clamping plate 202, thus initially compressing the laminated iron core 1 and aligning its top and bottom ends. Since the coil has already been installed, no adjustment is needed on either side of the laminated iron core 1. Rotate the rotating block 211 in the middle of the pull screw 210 in sequence, causing the pull screw 210 to rotate and pull the internal threaded tubes 209 at both ends closer together. This, in turn, pulls the fixed clamping plate 201 closer together. Adjust the compression nut 205 as needed to ensure that the final mating hole 301 and the heat dissipation hole 302 are aligned. During this process, the movable clamping plate 202 continues to compress the top and bottom ends of the laminated iron core 1, completing the fixation while aligning the top and bottom ends of the laminated iron core 1. This facilitates fixation while ensuring the flatness of the ends of the laminated iron core 1, resulting in a better assembly effect.

[0032] After the transformer with laminated iron core 1 is wired, before powering on, an insulating heat pipe 303 is embedded in the heat dissipation hole 302. The insulating heat pipe 303 is made of thermally conductive silicone. A heat pipe 305 is embedded in the insulating heat pipe 303 in a position that does not obstruct the wiring. Then, the connecting screw 308 at the end of the mounting ring 307 is rotated and embedded into the connecting screw hole 309 for installation and fixation. Through the high thermal conductivity of the heat pipe 305, the heat dissipated by the laminated iron core 1 during operation can be transferred to the heat dissipation fins 306 for heat dissipation, effectively reducing the internal temperature of the laminated iron core 1 and preventing it from overheating and causing safety problems.
