[0002] As compressed air production equipment, air compressors now have a wide range of application scenarios in industry. When air compressors compress air, air compression will generate a lot of heat energy.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] like Figure 1 , 2 As shown in Figure 3, the present embodiment includes a plurality of cooling components 1, and the plurality of cooling components 1 are evenly distributed on the outer walls around the inner cavity of the air compressor. The cooling component 1 includes an air inlet 2 and a cooling pipe 3. The air inlet 2 is sealed on both sides of the cooling pipe 3. The cooling airflow enters the cooling pipe 3 from the air inlet 2, and is then discharged from the air outlet 5 that passes through the upper part of the cooling pipe 3, taking away the heat on the outer wall of the inner cavity of the air compressor, and being discharged from the exhaust port 4 at the bottom of the cooling component 1, thereby playing a role in cooling the inner cavity of the air compressor and preventing dust from accumulating in the cooling device and affecting the cooling efficiency.

[0030] In this embodiment, a cooling device 6 is provided inside the cooling tube 3. The cooling device 6 contains a cooling medium for the cooling gas to pass through, so as to reduce the temperature of the cooling gas and improve the cooling effect. Shut-off valves 9 are provided at the air inlets 2 at both ends of the cooling tube 3. The shut-off valves 9 are used to isolate the interior of the cooling tube 3 from the air inlet 2. When no gas enters the cooling tube 3, the shut-off valve 9 is closed to prevent the cooling medium from flowing out of the air inlet 2 to cause leakage, thereby ensuring the cooling effect. The horizontal maximum height of the air inlet 2 is greater than the horizontal height of the cooling device 6, which further ensures that the cooling medium will not leak from the air inlet 2. A recovery plate 7 is provided at the upper end of the cooling device 6. The recovery plate 7 is inclined above the center of the cooling component 1. The inclined recovery plate 7 can effectively recover the cooling medium and reduce the loss of the cooling medium.

[0031] In this embodiment, a filtering device 8 is further provided between the air inlet 2 and the air-locking valve 9. The filtering device 8 is used to filter large particles of impurities in the air to prevent the large particles of impurities from colliding with the air-locking valve 9 and causing damage to the air-locking valve 9, thereby ensuring the safety of the air-locking valve 9, increasing the service life of the air-locking valve 9, and preventing subsequent cooling medium from leaking from the damaged air-locking valve 9.

[0032] In this embodiment, the exhaust port 4 is connected to the bottom of the cooling component 1 by a fixing component. In this embodiment, the exhaust port 4 and the cooling component 1 can be connected by a limiting slot, or the sub-button on the exhaust port 4 can be fixedly connected with the mother button on the cooling component 1, thereby ensuring the stability of the connection of the exhaust port 4, avoiding the generation of cooling airflow to blow the exhaust port 4 and causing the exhaust port 4 to loosen, and the exhaust port 4 can be frequently disassembled and cleaned to avoid dust accumulation that affects the cooling effect.

[0033] In this embodiment, the top of the cooling component 1 is an arc-shaped inner wall, the cooling pipe 3 is located on the side of the cooling component 1 away from the outer wall of the inner cavity, the air outlet direction of the air outlet 5 is facing the top of the cooling component 1, and the cooling pipe 3 is located on the side of the cooling component 1 away from the outer wall of the inner cavity of the air compressor, so that the cooling airflow has enough space to contact the outer wall of the inner cavity of the air compressor, and the diversion of the cooling airflow is reduced, thereby improving the cooling effect.

[0034] In this embodiment, the cooling tube 3 is detachably connected to the cooling assembly 1, and both ends of the cooling tube 3 are sealed with the air inlet 2. The detachable cooling tube 3 ensures the replaceability of the cooling tube 3, which is not only convenient for replacing damaged cooling tubes 3, but also convenient for adding new cooling media, thereby improving the convenience of use.

[0035] When this embodiment is actually used, the air inlet 2 is sealed and connected with the air outlet of the air cooling device to discharge the cooling gas, and the air-closing valve 9 is opened to facilitate the cooling gas to enter the air-closing valve 9 from the air inlet 2 and then enter the cooling device 6. Due to the nature of the gas itself, after being cooled by the cooling medium, it escapes from the cooling device 6 and is discharged from the air outlet 5 to between the cooling component 1 and the outer wall of the inner cavity of the air compressor, taking away the heat of the outer wall of the inner cavity of the air compressor, and then discharged from the exhaust port 4 to achieve cooling of the inner cavity of the air compressor. The detachable exhaust port 4 and cooling pipe 3 improve the replaceability of the entire cooling component 1, improve the convenience of use, and facilitate cleaning.

[0036] In the above description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the above examples are merely preferred implementation methods of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
