An air outlet frame 4 is provided above the air vent. The bottom of the air outlet frame 4 is fixedly connected to the top of the top cover 3. Heat dissipation plates 2 are provided on both sides of the housing 1. The heat dissipation plates 2 are hinged to the outer wall of the housing 1. Cooling components are fixedly connected to both sides of the inner wall of the housing 1. The cooling components include an inlet pipe 9, an outlet pipe 10, and a heat dissipation radiator 1. 1. Cooling pipes 12 and mounting brackets 13; the mounting brackets 13 are fixedly connected to a designated position on the inner wall of the housing 1 and are used to support the heat sink 11; the heat sink 11 is made of metal and has embedded cooling pipes 12 inside, which are used to contain and transport coolant; one end of the cooling pipes 12 is connected to the coolant storage tank through the inlet pipe 9, and the other end is connected to the liquid storage tank through the outlet pipe 10 to form a complete liquid circulation path; a fan 8 is provided on one side of the heat sink 11, two fans 8 are symmetrically arranged on both sides of the heat sink 11, and four fans 8 are provided on both sides of the inner wall of the housing 1 through the heat sink 11;

[0023] It should be noted that the housing 1 serves as the external protective shell for the entire heat dissipation system. Its internal space accommodates the generator 7 and cooling components. The outer wall is equipped with a hinged heat dissipation plate 2 for easy ventilation and maintenance. The mounting rack 5 is fixed to the bottom of the housing 1, supporting the generator 7. Multiple ventilation holes 6 are opened at the top to facilitate the exhaust of hot air and help form an upward and downward convection airflow, improving the overall heat dissipation effect. The top cover 3 is located at the top of the housing 1, serving as a seal and air guide. Air vents are located in the middle or on both sides of the top cover 3 to exhaust high-temperature gases. An exhaust rack 4 is fixed above the air vents to guide the directional exhaust of hot air and prevent backflow. The heat dissipation plate 2 is hinged to the outer wall of the housing 1 and can be opened or closed. When open, it increases the air intake area and enhances airflow. The plate is equipped with a filter and a louver. The louver structure provides dust protection without affecting ventilation. The cooling components are symmetrically arranged on both sides, located on the inner walls of both sides of the housing 1. The mounting bracket 13 is fixed to the inner wall of the housing 1 to support the heat dissipation radiators 11. The heat dissipation radiators 11 are made of metal (such as aluminum or copper) and have embedded cooling pipes 12. The coolant enters the cooling pipes from the storage tank through the inlet pipe 9, absorbs heat, and then flows back to the storage tank through the outlet pipe 10, forming a closed loop. Each heat dissipation radiator 11 has two fans 8 on one side, for a total of four fans 8 symmetrically distributed on both sides of the housing 1. Each heat dissipation radiator 11 has two fans 8 on one side, for a total of four fans. The fans 8 are symmetrically arranged on both sides of the inner wall of the housing 1, forming positive and negative pressure airflow channels. The symmetrical dual-fan configuration can significantly improve the heat exchange efficiency of the heat dissipation radiators 11, especially suitable for high heat load conditions.

[0024] In the specific implementation process, refer to Figure 4-5As shown, this utility model provides a heat dissipation structure for a generator. Filters 19 are mounted on both sides of the housing 1 via fixing components. The outer wall of the housing 1 has mounting grooves for the filters 19, and limit grooves are formed at the four corners of the mounting grooves. The fixing components include a button 20, an outer post 21, a locking ball 22, a spring 23, and a groove 24. The inner wall of the limit groove is slidably connected to the outer wall of the outer post 21. Multiple sliding grooves are equidistantly formed on the bottom outer wall of the outer post 21, and the inner wall of the sliding grooves is slidably connected to the outer wall of the locking ball 22. The inner wall of the outer post 21 is slidably connected to the outer wall of the button 20. The bottom of the button 20 has a groove 24 for accommodating the locking ball 22. The bottom of the button 20 is fixedly connected to the top of the spring 23, and the bottom of the spring 23 is fixedly connected to the outer wall of the outer post 21. A fixed frame 14 is fixedly connected to the bottom of the inner wall of column 21 and one side of the outer wall of box 1. A drive motor 15 is fixedly connected to the top of the fixed frame 14. A threaded rod 16 is fixedly connected to the output end of the drive motor 15. One end of the threaded rod 16 passes through the top of the fixed frame 14 and extends to the bottom of the inner wall of one side of the fixed frame 14. A scraper 17 is threadedly connected to the outer wall of the threaded rod 16. A guide rod 18 is slidably connected to the other end of the scraper 17. One end of the guide rod 18 is fixedly connected to the top of the inner wall of the other side of the fixed frame 14. The other end of the guide rod 18 extends to the bottom of the inner wall. A cleaning brush is fixedly connected to the side of the scraper 17 facing the filter screen 19. Two fixed frames 14, drive motor 15, threaded rod 16, scraper 17 and guide rod 18 are provided on both sides of box 1.

[0025] It should be noted that the housing 1 has mounting slots on both sides for embedding and installing the filter screen 19. The four corners of the mounting slots have limiting slots for quick locking with the fixing components. The outer column 21 is slidably connected in the limiting slots and serves as the main support structure of the fixing components. The bottom of the button 20 has a groove 24 for accommodating the locking ball 22. The spring 23 provides a restoring force so that the locking ball 22 automatically engages in the limiting slot after the button 20 is released. The locking ball 22 can slide in the groove, realizing the function of unlocking when the button 20 is pressed and automatically locking after being released. The fixing bracket 14 is located on one side of the outer wall of the housing 1 to support the entire cleaning system. The drive motor 15 drives the threaded rod 16 to rotate, controlling the scraper 17 to move up and down. The scraper 17 moves smoothly through the guide rod 18 to avoid deviation. The cleaning brush adheres to the surface of the filter screen 19 and completes the automatic dust removal operation as the scraper 17 moves up and down.

[0026] The working principle of this utility model is as follows: The generator 7 is placed on the rack 5 inside the housing 1. The rack 5 has a vent 6 at the top to facilitate air circulation and assist in heat dissipation at the bottom, ensuring that the coolant tank is full of coolant and the liquid circulation system is in normal condition. The coolant enters the cooling pipe 12 from the storage tank through the inlet pipe 9. The coolant circulates in the embedded cooling pipe 12, absorbing the heat generated by the generator 7. After absorbing heat, the coolant returns to the storage tank through the outlet pipe 10 to complete the cooling. At the same time, the fan 8 is started and symmetrically arranged on both sides of the heat dissipation radiator 11 to form an airflow channel. The fan accelerates the airflow and improves the heat exchange efficiency of the heat dissipation radiator 11. External air enters the housing through the filter screens 19 on both sides of the housing 1. The heat dissipation plate 2 is hinged and can be opened and closed according to the ambient temperature. After the hot air rises, it is discharged from the top cover 3. The air is discharged through the vent, and the air outlet frame 4 guides the hot air to be discharged in a directional manner to avoid hot air backflow. When installing the filter screen 19, insert it into the installation groove on the outer wall of the housing 1, align the four corners of the filter screen 19 with the limit groove, press the button 20, compress the spring 23, and the locking ball 22 retracts into the groove 24, so that the outer column 21 slides into the limit groove. Release the button 20, the spring 23 resets and pushes the locking ball 22 into the limit groove to achieve fixation. When disassembling, press the button 20 again, and the locking ball 22 retracts to remove the filter screen 19. When the dust on the surface of the filter screen 19 reaches a certain amount, the drive motor 15 starts, the drive motor 15 drives the threaded rod 16 to rotate, and controls the scraper 17 to move up and down along the guide rod 18. The cleaning brush adheres to the surface of the filter screen 19 and removes the dust with the movement of the scraper 17. After cleaning, the scraper 17 returns to the initial position and stops operation.

[0027] The heat dissipation structure of this generator has the following advantages: water cooling absorbs heat through embedded cooling pipes 12, and air cooling enhances the heat exchange efficiency of the radiator 11 through the symmetrical arrangement of dual fans 8. The housing 1 is equipped with vents 6, an exhaust rack 4, and a heat dissipation plate 2 to form a good air convection path. The dual-sided cooling component layout ensures a balanced temperature distribution inside the housing 1 and prevents local overheating. The filter screen 19 is fixed by a button 20 for unlocking, a spring 23 for resetting, and a locking ball 22 for limiting, achieving tool-free installation and disassembly, which is convenient for users to clean or replace regularly. The mounting groove and the limiting groove cooperate to improve sealing and stability. The drive motor 15 drives the threaded rod 16 to rotate, controlling the scraper 17 to move up and down, and the cleaning brush adheres to the surface of the filter screen 19 to automatically remove dust.
