[0002] A screw air compressor is a positive displacement air compressor. Its core component is a screw rotor, which compresses gas and increases the pressure of compressed air through the rotational motion of the rotor within the casing. It is widely used in various fields such as industrial manufacturing, chemical industry, pharmaceuticals, food and beverage, and energy, providing power to various tools and equipment on the production line. It also plays an important role in traditional pneumatic applications such as tire inflation and gas separation. Screw air compressors have advantages such as high compression efficiency, stable operation, low noise, and convenient maintenance. However, due to limitations in rotor rigidity and bearing life, they are generally suitable for medium and low pressure ranges.

[0003] Based on the above, the inventors have discovered the following problems: Most screw air compressors are installed inside a housing, and a cooling fan is installed on the surface of the housing for heat dissipation. However, when the cooling fan is damaged and needs to be repaired, the power cord of the cooling fan extends into the power distribution cabinet inside the housing. Therefore, when removing the cooling fan, it is necessary to open the cabinet door and remove the power cord, which is quite troublesome.
