Technical Field
[0001] This utility model relates to the field of generator manufacturing technology, and in particular to a generator silicon steel lamination with an integrated T-shaped heat dissipation component. Background Technology
[0002] Generators are key equipment in power systems, and the iron core is an important component of generators. The iron core is usually made of multiple layers of silicon steel laminations. The quality of the laminations and the assembly precision directly affect the performance and efficiency of the generator.
[0003] In the existing iron core assembly process, it is usually necessary to stack the stamped sheets manually or with the help of simple tooling. This method is highly dependent on the experience of workers and it is difficult to accurately control the overall stacking height of the iron core, resulting in poor consistency between different batches of iron cores.
[0004] Furthermore, if circumferential misalignment of the laminations occurs during the stacking process, it will affect the magnetic circuit characteristics and structural stability of the core. More importantly, during generator operation, the windings generate a large amount of heat, which is transferred to the core. Because traditional silicon steel laminations are tightly stacked, the heat inside the core is difficult to dissipate outwards, relying mainly on the surface of the core for heat dissipation, resulting in low heat dissipation efficiency. The accumulation of heat inside the core will cause the generator temperature to be too high, affecting the insulation performance of the windings and even shortening the generator's service life.
[0005] Therefore, this utility model proposes a generator silicon steel lamination with integrated T-shaped heat dissipation components to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems in the existing technology of generator silicon steel laminations, such as the difficulty in accurately controlling the overall height of the iron core during assembly and stacking, and the difficulty in dissipating heat inside the iron core after stacking, resulting in limited heat dissipation efficiency, this utility model aims to provide a generator silicon steel lamination with an integrated T-shaped heat dissipation component that has been structurally improved and can effectively solve the above problems.

The heat dissipation mechanism has a protrusion on the top of the stamped sheets, an airflow groove on the top of the protrusion, a ventilation groove on the top of the stamped sheets, a guide plate fixed to the inner wall of the ventilation groove, and a groove on the bottom of the stamped sheets.
[0009] Furthermore, the protrusion is embedded in the groove when multiple layers of stamped sheets are stacked, and a winding groove is provided on the inner side of the stamped sheet.

[0011] Preferably, the measuring mechanism further includes a button threadedly connected to the rear side of the slip ring, the button being used to pass through the slip ring and press against the support rod to fix the slip ring.
[0012] Preferably, the measuring mechanism further includes a support cylinder, the bottom of which is fixed to the top of the chassis, and a sliding groove is provided on the front side of the support cylinder.

It can quickly set the target height and improve the assembly quality and efficiency.
[0019] 2.

[0038] In a preferred embodiment, the airflow groove 302 and the ventilation groove 303 are structurally connected, and the guide vane 304 is disposed in the ventilation groove 303.
[0039] Working Principle: When assembling the generator core, the height is first set. The operator manually adjusts the position of the measuring rod 205 according to the predetermined height requirement of the core. The measuring rod 205 is slidably mounted on the outer wall of the support rod 203 via the slip ring 204. The support rod 203 is fixed to the chassis 1. The operator can hold the slip ring 204 or the measuring rod 205, causing the slip ring 204 to drive the measuring rod 205 up and down along the outer wall of the support rod 203. During this sliding process, the other end of the measuring rod 205 slides within the groove 202 of the support cylinder 201. The support cylinder 201 is fixed to the top of the chassis 1. The scale 209 on the front side of the support cylinder 201 provides the operator with a visual height reference. When the target height is reached, the operator turns the screw 206. The screw 206 is threaded onto the back side of the slip ring 204. The screw 206 will thread forward and press against the surface of the support rod 203. Through the reaction force, the slip ring 204 is firmly locked onto the support rod 203. The current position of rod 203 ensures that measuring rod 205 is also fixed at the target height. After the height is set, the stamping sheet 4 is stacked. The operator takes the stamping sheet 4 and aligns the limiting groove 208 on the outer wall of the stamping sheet 4 with the limiting rod 207 fixed on the top of the chassis 1. At the same time, the inner edge of the stamping sheet 4 with a central through hole is aligned with the outer wall of the support cylinder 201. The stamping sheet 4 slides down along the outer wall of the support cylinder 201 until it is placed stably on the top of the chassis 1. The matching relationship between the limiting rod 207 and the limiting groove 208 ensures that each layer of stamping sheet 4 will not rotate or misalign during the stacking process. The operator repeats this stacking action, stacking the stamping sheets 4 layer by layer. When the top of the stacked stamping sheet 4 touches the previously set measuring rod 205, it indicates that the iron core has reached the predetermined height. At this time, the stacking operation is stopped. The height measuring mechanism 2 solves the problem of difficulty in accurately controlling the height when stacking manually in this way.
[0040] During generator operation, the windings wound in the winding slots 5 generate a large amount of heat, which is transferred to the inside of the iron core. At this time, the heat dissipation mechanism 3 begins to function. The heat dissipation mechanism 3 is integrated on the stamped laminations 4. When multiple stamped laminations 4 are stacked, the protrusions 301 on the top of the lower stamped lamination 4 will be embedded in the grooves 305 at the bottom of the upper stamped lamination 4, achieving tight stacking. At the same time, the airflow grooves 302 opened on the top of the protrusions 301 will not be blocked, but will form a radial heat dissipation channel penetrating the inside of the iron core after stacking. The hot air inside the iron core will enter these airflow grooves 302 under the action of temperature difference and air pressure difference, and flow from the inside to the outside of the iron core along the airflow grooves 302. When the airflow reaches the outer end of the protrusions 301 When the airflow groove 302 and the ventilation groove 303 are structurally connected, the hot air then flows into the ventilation groove 303 opened on the top of the stamping plate 4. After the multiple stamping plates 4 are stacked, the ventilation groove 303 forms an axial heat dissipation channel that runs through the iron core. The airflow turns into axial flow in the ventilation groove 303. On the inner wall of the ventilation groove 303, the guide plate 304 is also fixed. The guide plate 304 is set in the ventilation groove 303 and has a specific guide angle to guide the axially flowing hot air, so that the hot air can be discharged from the iron core more smoothly. Through this T-shaped composite structure of the radial channel provided by the airflow groove 302 and the axial channel provided by the ventilation groove 303, the problem of the heat inside the iron core is difficult to dissipate efficiently is solved.
