By fixing the heat dissipation device inside the end cover shell, when the generator is working, the mechanical heat generated inside the generator can be discharged to the outside through the heat dissipation device, and the heat dissipation of the generator drive end cover is achieved through the contact between the arc-shaped heat conductive block and the outside air.

[0004] However, since the number of arc-shaped heat-conducting blocks in the above device is unknown, the heat dissipation performance of the generator end cover may be poor due to the small number of arc-shaped heat-conducting blocks. Therefore, it is necessary to improve the heat dissipation performance of the generator end cover.

[0005] Therefore, it is necessary to provide a new type of generator drive end cover to solve the above problems.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] like Figure 1-4 As shown, the present application provides a novel generator drive end cover, comprising an end cover shell 1, with a plurality of fixing blocks 2 fixedly connected to the arc surface of the end cover shell 1. The fixing blocks 2 can fix the end cover shell 1 on the generator body.

[0031] like Figure 1 and Figure 2As shown, the heat dissipation mechanism 3 includes a circular column 31 fixedly connected to the end cover shell 1, a receiving ring 35 is slidably connected to the circular arc surface of the circular column 31, a plurality of screw holes 32 are provided on the receiving ring 35, the receiving ring 35 is fixedly connected to the circular column 31 by fastening bolts 33, a plurality of heat-conducting rods 37 are fixedly connected to the circular arc surface of the receiving ring 35, one end of the heat-conducting rod 37 is fixedly connected to the arc-shaped heat-conducting block 36, a plurality of arc holes 34 are provided on the end cover shell 1, and the size of the arc holes 34 is consistent with the size of the arc-shaped heat-conducting block 36. The sizes of the blocks 36 are adapted and the numbers correspond one to one. Through the cooperation of the heat-conducting rod 37 and the arc-shaped heat-conducting block 36, the arc-shaped heat-conducting block 36 can continuously exchange heat with the outside air through the arc-shaped hole 34, thereby realizing heat dissipation inside the generator, thereby reducing the heat generation of the rotor and the power loss caused by mechanical heat, thereby reducing the power loss of the generator to a certain extent. At the same time, the arc-shaped heat-conducting block 36 is clamped in the arc-shaped hole 34, which can increase the stability of the connection between the receiving ring 35 and the circular column 31 to a certain extent.

[0032] It should be noted that in order to increase the stability of the connection between the circular column 31 and the end cover shell 1, a plurality of reinforcing ribs 38 are fixedly connected to the arc surface of the circular column 31. One side of the reinforcing rib 38 is fixedly connected to the end cover shell 1, and the reinforcing ribs 38 are cross-symmetrically arranged relative to the center point of the circular column 31. The support of the circular column 31 by the cross-symmetrically arranged reinforcing ribs 38 can improve the stability of the rotor rotation when the generator is working, thereby extending the service life of the generator.

[0033] like Figure 3 and Figure 4 As shown, the mounting mechanism 4 includes four connecting blocks 41 fixedly connected to the end cover shell 1, a circular heat conducting sheet 44 is placed directly below the connecting block 41, and a plurality of heat sinks 45 are fixedly connected to the circular heat conducting sheet 44, and a plurality of mounting blocks 42 are fixedly connected to the arc surface of the circular heat conducting sheet 44, and a circular hole 46 is opened on the mounting block 42, and a bolt rod 47 is threadedly connected to the inner wall of the connecting block 41, one end of the bolt rod 47 is fixedly connected to the pressing piece 49, and the end of the bolt rod 47 away from the pressing piece 49 is fixedly connected to the rotating block 48, and the bolt rod 47 is rotatably connected to the inner wall of the connecting block 41 with the help of the rotating block 48. The setting of the rotating block 48 can facilitate the operation of the bolt rod 47, and the number of mounting blocks 42 corresponds to that of the connecting blocks 41. The bolt rod 47 rotates inside the connecting block 41, thereby driving the pressing piece 49 to be stuck in the circular hole 46, thereby realizing the installation of the circular heat conducting sheet 44.

[0034] It should be noted that a coating area 43 is provided on the arc-shaped shell, and heat dissipation grease is coated on the coating area 43. The heat dissipation grease can better transfer the heat on the end cover shell 1 to the circular heat conductive sheet 44, thereby improving the heat dissipation effect of the circular heat conductive sheet 44.

[0035] At the same time, the arc-shaped heat conducting sheet, the heat conducting rod 37 , the circular heat conducting sheet 44 , and the heat sink 45 are all made of aluminum.

[0036] Working principle: During actual use, the end cover shell 1 can be connected to the generator body through the fixing block 2. At the same time, when the rotor in the generator rotates, the heat emitted will be transferred to the arc-shaped heat conducting plate, and finally the heat will be dissipated into the air outside the generator, thereby achieving heat dissipation inside the generator.

[0037] At the same time, in order to further improve the heat dissipation performance of the end cover shell 1, the bolt rod 47 can be rotated to make the pressing plate 49 fit into the circular hole 46, thereby realizing the installation of the circular heat conducting plate 44, and the heat sink 45 can increase the contact area between the circular heat conducting plate 44 and the air, thereby improving the heat dissipation performance of the circular heat conducting plate 44.

[0038] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
