Description

Technical field:

[0001] The utility model relates to the technical field of air compressor equipment, and more specifically to a single-head box-type air compressor. Background technology:

[0002] Air compressors are the main body of air source devices and are widely used in industrial production. Oil-free scroll air compressors provide clean, oil-free compressed air and are a new type of air compressor with development prospects.

[0003] For oil-free scroll air compressors, since they are oil-free compressors, the temperature of the compressed air is very high, and it needs to be cooled when it is output. The existing cooling method is to connect a radiator to the output end of the oil-free scroll air compressor head and directly blow the radiator with a fan to cool the compressed air entering the radiator. However, the fan requires additional electricity, which increases energy consumption and the effect is not ideal.

[0004] Moreover, there is no structure in the existing box to guide the wind blowing from the radiator, so the wind blowing to the radiator is directly dispersed and discharged through some heat dissipation holes in the box, with poor concentration. Moreover, the air after heat exchange is easy to flow back to the air compressor, affecting its cooling. Utility model content:

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a single-head box-type air compressor, which can blow the cooling air outlet of the oil-free scroll air compressor head directly toward the radiator, so that the compressed air in the radiator can be heat exchanged and cooled without the need to install an additional cooling fan, thereby reducing energy consumption. The interior of the utility model has an air guide structure, which can discharge the heat-exchanged gas from the exhaust through hole on the top plate of the main box body directly above the front wall plate of the main box body and the vertical fixing plate, and the exhaust is concentrated.
