Abstract

The invention discloses an air compressor box body realizing lifting heat dissipation and noise reduction. The air compressor box body realizing lifting heat dissipation and noise reduction comprisesa bottom plate, a top cover plate, a front door sheet, a rear door sheet, two side plates, four vertical frame columns and a box body frame, wherein an air inlet is formed in the front door sheet, a fan assembly and a lifting assembly, the lifting assembly controls lifting of the fan assembly, and a heat dissipation port is formed in the rear door sheet; and the fan assembly comprises a driving motor and an axial flow fan blade, wherein the axial flow fan blade comprises a hub and at least one blade, and the blade is arranged on the outer peripheral wall of the hub, a first flow guide groove is formed in the negative pressure surface of the blade, and the first flow guide groove comprises at least two sub-grooves arranged in the radial direction of the hub at intervals. According to the air compressor box body, a heat dissipation fan is mounted on the front door sheet, the fan can realize lifting heat dissipation, the heat dissipation effect is good; and meanwhile, blades of the fan are improved, so that the fan can also effectively reduce air supply noise.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor box body that can be raised and lowered to dissipate heat and reduce noise. Background technique [0002] An air compressor is a machine that compresses air to generate huge gas power. It is used to propel machinery, gas or liquid and has many uses. Air compressor air pumps can be divided into electric air pumps, manual air pumps and foot-operated air pumps according to the power source. Existing air compressors emit a large amount of heat energy during operation. After a short period of operation in a confined space, the high heat will cause poor compression efficiency or shutdown. [0003] Aiming at the situation of poor efficiency, in the prior art, a fan is installed in the box to realize heat dissipation, but the blades of the conventional fan are relatively smooth, and part of the air flow is easy to form a vortex air flow under the action of cent...

AI Technical Summary

Problems solved by technology

Existing air compressors will emit a lot of heat energy during operation, and after a short period of operation in a confined space, it will cause poor compression efficiency or shutdown due to high heat

[0003] Aiming at the situation of poor efficiency, in the prior art, a fan is installed in the box to realize heat dissipation, but the blades of the conventional fan are relatively smooth, and part of the air flow is easy to form a vortex air flow under the action of centrifugal force, resulting in relatively large noise. The air compressor itself will also generate a lot of noise when it is running, and the noise of the fan will increase the overall noise volume

Moreover, the heat dissipation effect of the fan of the prior art is not good
