The difference in temperature distributions over the cold and hot air flow cross-sections for the axial and radial arrangements of the counterflow vortex tube outlets has been experimentally established. In the case of axial arrangement of outlets of both the cold and hot air, temperature gradient over the flow cross-section depends on the ratio between the areas of outlet channel cross-sections. The minimum temperature is exhibited by the zones of secondary vortex structures. In the case of radial arrangement of the outlets of both the cold and hot air, temperature over the flow cross-sections evens out due to destruction of secondary large-scale vortex structures. Keywords: vortex tube, temperature separation, vortex structures.
