Description

one

The invention relates to refrigeration engineering, in particular, to vortex refrigeration units, and is intended to produce cold flow in air-conditioning and thermostatic systems,

The purpose of the invention is the development of adiabatic efficiency.

Figure 1 schematically shows the proposed vortex cooler; figure 2 - section aa in figure 1.

The vortex cooler contains a vortex tube 1 with a nozzle inlet 2, a diaphragm 3 of the cold flow outlet, a diffuser 4 and an additional gas inlet pipe 5 installed along the axis of the pipe 1 from the diffuser 4 side and connected to the latter through an additional heat exchanger 6 A tube 7 connected to the cavity and coaxially arranged and a cylindrical screen 8 forming with the bowl 7 and tube 5 a two-way channel 9 are installed for taking and returning the inhibited flow into the cavity of pipe 1. valve 10 is provided for outputting a hot flow from the cycle; Radial plates 11 are installed for braking and flow in channel 9.

Vortex cooler works in the following way.

2084292

Compressed gas from a source (not shown) is fed to the nozzle inlet 2, from where it enters the vortex tube 1, where it is divided into two streams. Cooled: the near axial flow through the diaphragm 3 flows to the consumer. The hot peripheral flow in the hot zone of the vortex tube is divided into two flows. The hottest layers, which are closer to the walls of the vortex tube 1, being pressed in the diffuser 4, enter the heat exchanger 6 where they are cooled. From the heat exchanger 6, part of the flow in the amount of 10–15% through the valve that controls the holding capacity of the valve 10 is removed from the cycle, and the rest through the pipe 5 of the additional flow is supplied from the di (5) side of the fuzor 4 to the axial zone of the vortex

20 of the tube 1, where it is mixed with the cooled axial flow, participates with it in the process of energy separation and passes through the diaphragm 3 to the consumer. The least heated layers of the peripheral flow, which are closer to the axis of the vortex tube, are braked by the radial plates 11 and due to the radial and axial pressure gradient along the two-way channel 9, 30 are given into the vortex tube 1, to the zone between the cooled axial and hot peripheral in streams.
