A device is disclosed comprising a tube with a hot gas outlet at a first end and a cold gas outlet at a second end, an inlet in fluid communication with the tube and an accelerator associated with the tube. The device is configured to accept a supply of compressed gas at the inlet, the accelerator causing the air to form a vortex inside the tube and the device producing a cold gas stream that exits from the cold gas outlet and a hot gas stream that exits from the hot gas outlet. The device may further include a ventilated heat shield surrounding at least a portion of the tube. Air flowing within the heat shield can contact the outside of the tube and the heat shield may extend past the first end of the tube. The device may include an orifice to supply air from the inlet to a space between the tube and the heat shield or the hot gas stream exiting the hot gas outlet may draw ambient air through the heat shield. In one embodiment, the accelerator includes a helical groove.
