Abstract
The invention relates to a vortex tube (1) for the generation of cold air. The vortex tube comprises a tube body (2) with a wall (5), the inner wall surface (6) of which forms a channel (7) with a circular-cylindrical cross section. A vortex generator (8) is arranged in a first end (9) of the channel (7) and a flow limiting body (10) is arranged in a second end (11) of the channel (7). One or several outlet/s (12) for hot air is/are arranged at the second end (11) of the channel (7). The vortex generator (8) has an opening (13) through which cold air may leave the channel. A conduit (14) for the supply of compressed air to the vortex generator (8) runs through the wall (5) of the tube body (2) in parallel with the inner channel (7) from a rear end (3) of the tube body (2) up to an inlet (15) to the vortex generator (8).
Claims12
A vortex tube for the generation of cold air, which vortex tube comprises a tube body with a wall, the inner wall surface of which forms an inner channel with a circular-cylindrical cross section, and wherein a vortex generator is arranged in a first end of the channel and a flow limiting body is arranged in a second end of the channel, and wherein at least one outlet for hot air is arranged at the second end of the channel and the vortex generator has an opening through which cold air may leave the channel in a first end of the channel, and wherein the vortex tube further has at least one conduit for the supply of compressed air to the vortex generator, and wherein said at least one conduit for the supply of compressed air extends in the same axial direction as the tube body and extends from a rear end of the vortex tube up to an inlet to the vortex generator, and in that the rear end of the vortex tube is adapted to be connected to a source of compressed air.
