[0002] Currently, brushless exciters are widely used in generator sets, and their rotary rectifier mechanism is one of the key components. The rotary rectifier mechanism typically includes a rotating disk, with rectifier elements mounted on both sides of the disk.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the existing structure has poor heat dissipation performance, the rectifier components are prone to overheating, affecting service life and system stability, and therefore needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a rotary rectifier mechanism for a brushless exciter, aiming to solve the aforementioned problems.

[0005] A rotary rectifier mechanism for a brushless exciter includes a rotary disk, characterized in that: the rotary disk includes two mounting disks, a heat sink is mounted between the two mounting disks, a plurality of heat sink fins are spaced apart along the circumferential edge of the heat sink, and the heat sink is detachably connected to the mounting disks by a fastener.

[0006] By adopting the above technical solution, the structure of using two mounting plates to clamp the heat sink makes the rotating rectifier mechanism more compact, while also facilitating disassembly and maintenance. The detachable connection design between the heat sink and the mounting plates allows for quick disassembly of the heat sink when maintenance is required, without disassembling the entire rotating rectifier mechanism, which greatly improves maintenance efficiency.

[0007] Optionally, the fixing component includes a fixing rod, one end of which is connected to a fixing block and the other end is threaded to a fixing cylinder for pressing against the mounting plate. One end of the fixing cylinder is connected to a connecting block, and fixing holes for the fixing rod to pass through are provided on the heat sink and the two mounting plates.

[0008] By adopting the above technical solution, the fixing rod can firmly fix the heat sink between the two mounting plates through the cooperation of the fixing block and the fixing cylinder. The threaded connection design of the fixing cylinder makes installation and disassembly more convenient, without the need for additional tools, thus improving installation efficiency and reliability.

[0009] Optionally, several heat-conducting blocks are connected to both sides of the heat sink, and each mounting plate has a corresponding heat-conducting groove for the heat-conducting blocks to be inserted.

[0010] By adopting the above technical solution, the heat-conducting block and the heat-conducting groove of the mounting plate can effectively conduct the heat generated by the heat sink to the mounting plate, and then conduct it to other heat dissipation components through the mounting plate, which greatly improves the heat dissipation efficiency and extends the service life of the rectifier components.

[0011] Optionally, guide posts are connected to both opposite sides of the heat sink, and each mounting plate has a guide groove for the guide posts to be inserted into. The height of the guide posts is greater than the height of the heat-conducting block.

[0012] By adopting the above technical solution, the cooperation between the guide column and the guide groove ensures the accurate positioning of the heat sink during installation, avoiding problems such as poor heat dissipation or unstable fixation caused by installation position deviation, and improving installation accuracy and reliability.

[0013] Optionally, the heat sink has several heat dissipation holes extending through its circumferential edge.

[0014] By adopting the above technical solution, the design of the heat dissipation holes increases the heat dissipation area, promotes air circulation, further improves heat dissipation efficiency, and effectively reduces the operating temperature of the rectifier components.

[0015] Optionally, the heat sink is made of aluminum alloy.

[0016] By adopting the above technical solution, aluminum alloy has good thermal conductivity and lightweight properties, which not only ensures good heat dissipation, but also reduces the weight of the rotary rectifier mechanism, which is conducive to improving the overall performance and efficiency of the brushless exciter.

[0029] This application discloses a rotary rectifier mechanism for a brushless exciter. (Refer to...) Figure 1 and Figure 2The system includes a rotating disk 1, which comprises two mounting disks 11, with a heat sink 2 installed between the two mounting disks 11. The heat sink 2 is made of aluminum alloy. Aluminum alloy has good thermal conductivity and is lightweight, ensuring good heat dissipation while reducing the weight of the rotating rectifier mechanism, which is beneficial to improving the overall performance and efficiency of the brushless exciter. Several heat sink fins 21 are integrally formed along the circumferential edge of the heat sink 2. The structure of the heat sink 2 being held between the two mounting disks 11 makes the rotating rectifier mechanism more compact and facilitates disassembly and maintenance. The detachable connection design between the heat sink 2 and the mounting disks 11 allows for quick removal of the heat sink 2 during maintenance without disassembling the entire rotating rectifier mechanism, greatly improving maintenance efficiency.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The heat sink 2 and the mounting plate 11 are detachably connected by a fastener 3, which includes a fixing rod 31. One end of the fixing rod 31 is fixedly connected to a fixing block 32, and the other end is threadedly connected to a fixing cylinder 33 for pressing against the mounting plate 11. One end of the fixing cylinder 33 is fixedly connected to a connecting block 34. Both the heat sink 2 and the two mounting plates 11 have fixing holes 4 for the fixing rod 31 to pass through. Through the cooperation of the fixing block 32 and the fixing cylinder 33, the fixing rod 31 can firmly fix the heat sink 2 between the two mounting plates 11. The threaded connection design of the fixing cylinder 33 makes installation and disassembly more convenient, requiring no additional tools and improving installation efficiency and reliability.

[0031] Reference Figure 2 and Figure 3 Several heat-conducting blocks 22 are integrally formed on both opposite sides of the heat sink 2. Each mounting plate 11 has a corresponding heat-conducting groove 111 for the heat-conducting blocks 22 to be inserted into. The heat-conducting blocks 22 cooperate with the heat-conducting grooves 111 of the mounting plate 11 to effectively conduct the heat generated by the heat sink 2 to the mounting plate 11, and then conduct it to other heat dissipation components through the mounting plate 11, which greatly improves the heat dissipation efficiency and extends the service life of the rectifier components.

[0032] Reference Figure 2 and Figure 3 Guide posts 23 are fixedly connected to both opposite sides of the heat sink 2. Each mounting plate 11 has a guide groove 112 for the guide post 23 to engage. The height of the guide post 23 is greater than the height of the heat-conducting block 22. The cooperation between the guide post 23 and the guide groove 112 ensures the accurate positioning of the heat sink 2 during installation, avoiding problems such as poor heat dissipation or unstable fixation caused by installation position deviation, thus improving installation accuracy and reliability.

[0033] Reference Figure 2 and Figure 3The heat sink 2 has several heat dissipation holes 24 extending along its circumferential edge. The design of the heat dissipation holes 24 increases the heat dissipation area, promotes air circulation, further improves heat dissipation efficiency, and effectively reduces the operating temperature of the rectifier components.

[0034] The implementation principle of a rotary rectifier mechanism for a brushless exciter according to an embodiment of this application is as follows: a plurality of heat sink fins 21 are integrally formed along the circumferential edge of the heat sink 2. The structure of using two mounting plates 11 to clamp the heat sink 2 makes the rotary rectifier mechanism more compact and facilitates disassembly and maintenance. The detachable connection design between the heat sink 2 and the mounting plates 11 allows for quick disassembly of the heat sink 2 when maintenance is required, without disassembling the entire rotary rectifier mechanism, greatly improving maintenance efficiency.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
