[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 A combined generator rotor comprises a center ring 1, a support ring 2, a support assembly and fins 3. The support ring 2 is arranged on the lower outer part of the center ring 1, and the support assembly is arranged on the outer side of the support ring 2. The support assembly comprises a bottom plate 4 and a connecting plate 5. The support assembly is in an inverted T shape. The connecting plate 5 is narrower at one end close to the bottom plate 4, and wider at one end away from the bottom plate 4. The fin 3 is provided with a connecting groove matched with the connecting plate 5. Friction blocks 6 are also embedded on both sides of the connecting plate 5, and the friction blocks 6 are matched with the connecting grooves. The fins 3 and the friction blocks 6 are arranged in several groups. The fin 3 is provided with a first pin hole at one end close to the center ring 1, and the support ring 2 is also provided with a second pin hole matched with the first pin hole.

[0021] In this embodiment, a guide groove is provided on the inner wall of the center ring 1 to facilitate auxiliary fixation. The support ring 2 provides stable support for the center ring 1. A support assembly is also provided on the support ring 2. The support assembly includes a base plate 4 and a connecting plate 5 which is larger at the top and smaller at the bottom. The fins 3 are plugged into the connecting plate 5. The base plate 4 and the support ring 2 provide a stable layer for the fins 3. A friction block 6 is also provided on the connecting plate 5 to ensure the stability of the connection between the fins 3 and the connecting plate 5. Preferably, the assembled rotor is plugged and stacked through the center axis cooperating with the center ring 1 and the pin rod cooperating with the first pin hole and the second pin hole.

[0022] During actual use, it is necessary to ensure that the fin 3 is stably fitted with the center ring 1 so that the first pin hole and the second pin hole can be aligned. For this purpose, a positioning rod 7 for assisting in fixing the fin 3 is also provided on the support ring 2. A slot matching the positioning rod 7 is provided at one end of the fin 3 close to the positioning rod 7. The positioning rod 7 is clamped with the fin 3, and the slot of the fin 3 is elastic to ensure the stability of its positioning assembly.

[0023] Traditional fins 3 are mostly closed structures, and several groups of heat dissipation holes of fins 3 pass through an overall heat dissipation cavity, resulting in low heat dissipation efficiency. For this reason, heat dissipation holes are also provided on the fins 3, and several groups of heat dissipation grooves are also provided at one end of the fins 3 away from the center ring 1. The several groups of heat dissipation grooves disperse the overall heat dissipation cavity into several groups of small cavities to improve the heat dissipation efficiency.
