Embodiment Construction

[0017] Such as figure 1 As shown, a vortex tube refrigerating device with a sleeve-type cold flow outlet includes a vortex chamber 1, a hot end pipe 2, and a sleeve-type cold end pipe 3; The end pipe 3 and the hot end pipe 2 are connected; the sleeve type cold end pipe 3 is a mutual coaxial structure composed of a central pipe 3-1 and at least one layer of outer casing 3-2 which are all communicated with the vortex chamber 1. Rotary channel.

[0018] Each flow channel of the central pipe 3-1 and the flow channel of the rotary body is connected to different cold fluid outlets 3-3 that can individually adjust their respective flow rates. The outlets flow out simultaneously, and under normal operating conditions, the several streams of cold fluid are at different temperatures.

[0019] The vortex chamber 1 has a tangential fluid inlet 1 - 1 through which high-pressure fluid flows in; the fluid inlet 1 - 1 of the vortex chamber 1 makes the fluid form a vortex flow in the vortex ...

Abstract

A vortex tube refrigeration device with a sleeve-type cold flow outlet is characterized in that it comprises a vortex chamber, a hot end pipe, and a sleeve-type cold-end pipe; The end pipes are connected; the sleeve type cold end pipe is a mutually coaxial rotary body flow channel composed of a central pipe and at least one layer of outer sleeves which are all communicated with the vortex chamber. Compared with the traditional vortex refrigerating tube, the present invention can draw out airflows with different temperatures from different radii of the outlet of the cold end of the vortex chamber, and switch different sources of cold air with the change of the working conditions of the vortex tube refrigerating device, and pass Adjust the flow of each cold air passage to adjust the working state of the vortex tube to adjust the cooling effect.

Description

Technical field: [0001] The invention belongs to the technical field of refrigeration in engineering thermophysics, and in particular relates to a vortex tube refrigeration device with a sleeve-type cold flow outlet. Background technique: [0002] Vortex refrigeration tubes have been used in many fields. When the fluid flows in the pipe in the form of a vortex, there will be energy transfer from the inner layer to the outer layer, so that the total temperature of the inner layer fluid is lower than that of the outer layer fluid, and the inner and outer fluids are respectively drawn out. Two fluids can obtain high temperature fluid and low temperature fluid respectively. In previous research and application, it was found that the temperature field at the cold fluid outlet of the vortex tube is not uniform, and the temperature at different radii is not consistent. The fluid temperature at some radii is lower than that at other regions, but this temperature difference varies wi...
