Auxiliary cooling system for coal mining equipment

The utility model discloses an auxiliary cooling system for coal mine equipment, and belongs to the technical field of mine equipment. The device mainly comprises a box body, wherein a compressed air inlet, a cold air outlet and a hot air outlet are formed in the side wall of the box body; a refrigeration bin is arranged in the box body; a compressed air conveying pipe, a flow dividing pipe, a vortex pipe, a cold air conveying pipe and a hot air conveying pipe are installed in the refrigerating bin. And a nozzle, a vortex chamber, a separation pore plate and a heat valve are arranged in the vortex tube. Compressed air is input into the vortex tube, is accelerated by the nozzle, enters the vortex chamber in the tangential direction, rotates at a high speed in the vortex chamber, generates an energy separation effect and is finally separated into cold air flow and hot air flow with different temperatures, and the cold air flow can be used for carrying out auxiliary cooling on coal mine equipment so as to prolon
