Cooling mechanism of screw air compressor

The utility model relates to the technical field of air compressors, in particular to a cooling mechanism of a screw air compressor, a ring pipe is wound on a main machine of the air compressor and is tightly attached to the outside of the main machine of the air compressor through a connecting plate and a flitch plate, the heat conduction effect is good, and then cooling water in a water tank is pumped into the ring pipe through a water pump. Heat of the air compressor main machine is taken away through flowing of cooling water, the cooling effect is good, rapid heat dissipation during cooling is facilitated through cooperation of the heat dissipation pipe and the draught fan, and the cooling effect is effectively improved; comprising a base, a shell and an air compressor host, the shell is fixedly arranged at the top of the base, and the air compressor host is fixedly arranged at the top of the base and located in the shell; the air compressor further comprises an air inlet pipe, an air outlet pipe, a cooli
