발명의 명칭: Vortex tube
1. A vortex tube comprising: a main body having a hollow tube shape with a cylindrical inner cavity defined in the main body; an inlet coupled to a back side of the main body and into which compressed air is configured to be introduced; an air circulating chamber having a hollow tube shape with a cylindrical inner cavity defined in the air circulating chamber, the air circulating chamber installed coaxially in the cylindrical inner cavity of the main body and having an outer passage channel of annular shape defined between a cylindrical inner surface of the main body and a cylindrical outer surface of the air circulating chamber for allowing passage of compressed air through the outer passage channel; a vortex generator coupled to a front side of the air circulating chamber so as to enable the compressed air introduced through the outer passage channel to spin and move backwardly into the cylindrical inner cavity of the air circulating chamber; a cold air-outlet coupled to a front side of the main body and through which cold air is configured to be discharged outside from the cylindrical inner cavity of the air circulating chamber; and a hot air-outlet coupled to a back side of the air circulating chamber and through which hot air is configured to be discharged outside from the cylindrical inner cavity of the air circulating chamber.
