Vortex tube refrigerating device with sleeve type cold flow outlet

Abstract

A vortex tube refrigerating device with a sleeve type cold flow outlet is characterized by comprising a vortex chamber, a hot end tube and a sleeve type cold end tube; two sides of the vortex chamber are respectively connected with the sleeve type cold end tube and the hot end tube; and the sleeve type cold end tube is a mutually coaxial revolving body flow channel composed of a central tube and at least one layer of outer sleeve which communicate with the vortex chamber. Compared with a traditional vortex refrigerating tube, the vortex tube refrigerating device has the advantages that air flows with different temperatures can be led out from positions with different radii of the cold end outlet of the vortex chamber, different cold air sources are switched along with change of the working condition of the vortex tube refrigerating device, and the working state of the vortex tube is adjusted by adjusting the flow of different cold air flow channels so as to adjust the refrigerating effect.

Description

Technical field: [0001] The invention belongs to the technical field of refrigeration in engineering thermophysics, and specifically 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, energy transfers from the inner layer to the outer layer, so that the total temperature of the inner fluid is lower than that of the outer fluid, which leads to the inner and outer layers respectively. Two streams of fluid can obtain high temperature fluid and low temperature fluid respectively. Past research applications have found that the temperature field at the cold fluid outlet of the vortex tube is not uniform, and the temperature at different radii are not consistent. The fluid temperature at some radii is lower than the fluid temperature in other areas, but this temperature difference varies with It disappears as ...
