[0028] like Figure 1-3 As shown, this application provides a cooling device for a nitrogen compressor motor, including a housing 1 and a motor body 2. The motor body 2 is disposed inside the housing 1, and the output shaft of the motor body 2 extends outside the housing 1. The top of the housing 1 is provided with an opening, and a suitable heat dissipation cover 3 is provided inside the opening. The heat dissipation cover 3 is evenly provided with multiple heat dissipation holes. The top of the housing 1 is provided with a locking component 4 for locking the heat dissipation cover 3 at the opening. Air inlets are provided on both the front and rear sides of the housing 1. A blower component 5 and an air filter component 6 are detachably connected to the air inlets. The blower component 5 is located inside the air filter component 6. By setting the air filter component 6, dust in the air is filtered, preventing external cold air from being directly blown into the housing 1 when the blower component 5 is operating. This effectively reduces the generation of dust on the surface of the motor body 2, ensures the normal dissipation of motor heat, guarantees heat dissipation efficiency, and at the same time prevents corrosive substances in the dust from corroding the motor, ensuring the service life of the motor.

[0029] like Figure 1 and Figure 3As shown, the blower assembly 5 includes a fan 51 and a mounting frame 52. A set of plug-in posts 7 are symmetrically arranged at the air inlet. The fan 51 is fixed on the mounting frame 52. The mounting frame 52 is provided with a first plug-in hole that matches the plug-in post 7. The mounting frame 52 is connected to the plug-in post 7 through the first plug-in hole. The plug-in post 7 facilitates the assembly and disassembly of the mounting frame 52.

[0030] like Figure 1 and Figure 3 As shown, the air filter assembly 6 includes an air filter frame 61, a first insertion shaft 62, a second insertion shaft 63, and a filter cloth 64. The air filter frame 61 is provided with a second insertion hole that matches the insertion post 7. The air filter frame 61 is connected to the insertion post 7 through the second insertion hole. One end of the filter cloth 64 is fixedly connected to the first insertion shaft 62, and the other end of the filter cloth 64 is connected to the second insertion shaft 63. The air filter frame 61 is provided with a first insertion groove that matches the first insertion shaft 62 and a second insertion groove 612 that matches the second insertion shaft 63. The first insertion shaft 62 is inserted into the first insertion groove 611, and the second insertion shaft 63 is inserted into the second insertion groove 612. Through the cooperation of the first insertion shaft 62 and the first insertion groove, and the cooperation of the second insertion shaft 63 and the second insertion groove 612, it is convenient to remove the filter cloth 64 from the air filter frame 61 for cleaning or replacement.

[0031] like Figure 1 and Figure 3 As shown, the end of the plug-in post 7 away from the air inlet is threaded, and the plug-in post 7 is threadedly connected to the locking nut 8. Specifically, when installing the blower assembly 5 and the air filter assembly 6, first connect the mounting frame 52 with the fan 51 to the plug-in post 7 through the first plug-in hole, then connect the air filter frame 61 to the plug-in post 7 through the second plug-in hole, then insert the first plug-in shaft 62 into the first plug-in slot and the second plug-in shaft 63 into the second plug-in slot to keep the filter cloth 64 in a taut state, and finally thread the locking nut 8 to the plug-in post 7 to fix the filter frame.

[0032] like Figure 1 and Figure 2 As shown, there are two locking components 4, which are symmetrically arranged. Each locking component 4 includes a locking pin 41, a pressing block 42, and a limiting block 43. The lower end of the locking pin 41 is fixed to the housing 1, and the upper end of the locking pin 41 moves through the pressing block 42. The limiting block 43 is fixed to the upper end of the locking pin 41. By rotating the pressing block 42 to the top of the heat dissipation cover 3, the heat dissipation cover 3 is pressed against the opening. The locking components 4 make it easy to remove the heat dissipation cover 3 from the opening, which facilitates the maintenance of the motor inside the housing 1.

[0033] like Figure 2 and Figure 3As shown, a support frame 9 is fixed inside the housing 1, and the motor body 2 is fixed on the support frame 9. Specifically, the support frame 9 is hollow, which can increase the contact area of ​​the cold air entering the housing 1 of the motor body 2 and improve the cooling efficiency of the motor body 2.

[0034] like Figure 2 and Figure 3 As shown, a rubber pad 10 is provided between the support frame 9 and the motor body 2. The rubber pad 10 can reduce the vibration generated by the motor body 2 during operation and enhance the stability of the motor operation.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
