A heat dissipating system of a high-speed circular knitting machine is provided to jet the cold air from a cold air outlet of a cryogenic air gun, thereby removing the high heat generated by a base portion of a cylinder during a knitting process. A cryogenic air gun(100) includes an air inlet(101), a cold air outlet(102), a swirl generating chamber(103), a brake(104) and a high temperature air outlet(105). The air inlet, cold air outlet and swirl generating chamber are installed at an end of the cryogenic air gun. The brake and high temperature air outlet are installed at the other end of the cryogenic air gun. A compressed air is introduced toward the outside of the swirl generating chamber through the air inlet and injected toward the tangential direction as the sound-speed expansion so that the high speed swirl is generated from A point to B point. |
