Preferably, in this embodiment, the cooler 9 is in abutment connection with the outlet of the air guide channel, and the area of the upper surface of the cooler 9 is larger than the cross-sectional area of the outlet of the air guide channel. The above arrangement enables the cooling gas flowing out of the air guide channel to completely enter the cooler 9, thereby avoiding the waste of cooling air.

Of course, in an alternative embodiment not shown in the drawings of the present invention, at least part of the cooler 9 may also be placed in the air guide channel, as long as the cooling air flowing out of the air guide channel outlet can be fully entered into the cooling The technical solutions of the device are all within the protection scope of the present application.

As shown in FIG. 1 to FIG. 4, in the first embodiment of the present invention, the compressor pump body assembly includes a cover plate 6, a static plate assembly, and an end cover 10. The static plate assembly is located between the cover plate 6 and the end cover 10, and the cover plate 6, the static plate assembly 51, and the end cover 10 surround at least a part of the air guide channel.

Specifically, one end of the static disk assembly 51 is connected to the cover plate 6, and the other end of the static disk assembly 51 is connected to the end cover 10, so that the cover plate 6, the static disk assembly 51, and the end cover 10 form an air guide channel to guide the wind.

The comb teeth 511 can accelerate the heat generated when the cooling gas takes the moving plate 52 and the static plate 512 to compress air. A passage for cooling air to flow is formed on the side of the static disk 512 near the cover plate 6, thereby improving the reliability of the air compressor. In this embodiment, the comb teeth 511 may be of equal thickness design or have a certain draft angle, and some columnar structures are arranged in the middle of the adjacent comb teeth 511, as shown in FIG. 13, to improve the disturbance of the air, Thereby, the heat exchange efficiency of the comb teeth 511 is improved.

When the air compression works randomly, the driving unit 1 drives the fan 2 to rotate together. Preferably, the fan 2 here is a multi-wing centrifugal fan, and the air inlet of the fan 2 faces the side close to the pump body component of the compressor. Of course, if the cooling of the driving part 1 is to be considered, the air inlet of the fan 2 can also be arranged on the side facing the driving part 1, so that the rotation of the fan 2 can simultaneously take away the heat generated by the driving part 1 while working, thereby eliminating the need for the driving part. 1 A separate fan is provided for heat dissipation, which saves costs and makes the structure of the air compressor more compact.

The flow direction of the cooling gas in the air guide channel is shown by the arrow in FIG. 14. During the operation of the air compressor, the temperature of the cooling gas that has absorbed the heat of the driving unit 1 will rise to a certain extent. As a result of the temperature rise test, the temperature rise of the drive unit 1 is not large, so it will not cause a relatively bad impact on the working environment of the fan 2.
