Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1 and 2, the embodiment provides an outlet cooling air compressor, which includes an inlet end 2, a compression pump body 1, a pump body housing 4, an outlet end 3, and a secondary pressure increasing pipe 5.
Wherein, this pump body shell 4 is the hollow cylinder structure, establishes the installation cavity in it, and the compression pump body 1 is inserted and is located in this pump body shell 4, and the both ends of this pump body shell 4 respectively are equipped with a flange 42, and then, make this inlet end 2 and give vent to anger and hold 3 and locate respectively on this flange to realize this inlet end 2 and give vent to anger and hold 3 and be fixed in on this compression pump body 1 respectively.
Meanwhile, the air outlet of the compression pump body 1 is communicated to the air outlet end 3 through the secondary pressurization pipe 5, so that secondary pressurization of compressed air is realized.
In this embodiment, the air outlet end 3 includes a spiral outlet pipe 31, and fins 32 are uniformly distributed on the outer wall of the spiral outlet pipe 31, so that the air outlet end 3 is integrated with the fins 32, and an intercooler is formed to cool the gas of the second-stage compression.
