Abstract

The utility model relates to a vortex pipe refrigerating device, which comprises a vortex room wall pipe which is arranged in a pipe body, a hot air pipe and a hole plate seat. The base hole plate is orderly loaded in the pipe body from one end of the pipe body and is fixed with nuts; a throat pipe and a cold air duct are orderly loaded in the pipe body from the other end of the pipe body, and are fixed through the nuts. The utility model which is particularly suitable for refrigerating and cooling devices worked under high temperature environment has the advantages of simple structure, small size, light weight, low cost, convenient installation and operation, longtime and continuous use, high refrigerating and cooling efficiency, etc.

Description

Vorter pipe refrigerator

The utility model relates to a kind of vortex tube refrigerator, belongs to refrigerating appliance, and the instrument and equipment that is particularly suitable for working in hot environment cools; Also available its made small-sized air-conditioner.

Refrigeration Technique in the past, generally be to adopt traditional compressor and freon or ammonia refrigerant to realize, though effect is better, but complex structure, take up room big, cost is high, mobile, the maintenance inconvenience, environment for use is required also strict, more can not be used for cooling of the instrument and equipment of working in hot environment; Past uses electric fan that it is cooled usually, and what also have is loaded on it in thermal insulation protection cover, cover is cooled off again; often because environment temperature is higher; cause effect not ideal enough, the discontinuous operation of have to start-stop stopping, what influence was produced normally carries out.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, in light weight, cost is low, installation, easy to use, need not keep in repair, can use continuously for a long time, vortex tube refrigerator that the efficient that cools is high.

The purpose of this utility model realizes by the following technical solutions: comprise body, eddy current locular wall pipe is packed in the body, heating pipe, orifice plate seat, orifice plate are put into body in turn from an end of body, locate with nut, trunnion, refrigerator pipe are put into body successively from the other end of body, fix by nut.

One side of described eddy current locular wall pipe is provided with nozzle along its inwall tangential direction.

The inlet end of the inner chamber of described trunnion is a cylindrical section, is the diffuser of platform taper thereafter.

The utility model compared with prior art, owing to utilize compressed air, tangentially enter the minor air cell through nozzle with very high speed, and form a series of vortex effect such as free vortex flow, thereby realize the refrigeration purpose, and the results showed its refrigeration ideal, simple in structure, cost is low, need not keep in repair, can use continuously for a long time, the efficient that cools advantages of higher, implement simultaneously to be beneficial to and to apply easily.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is the A-A cross-sectional view.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, and body 8 is with the stainless steel tube moulding, and eddy current locular wall pipe 6 is put in the body 8, and heating pipe 4, nut 5, orifice plate seat 2, orifice plate 3 are in an end of body 8 is packed body 8 in turn into, and be fixing with nut 1; Trunnion 7, refrigerator pipe 9, put into body 8 successively from the other end of body 8, fixing with nut 10; Side at eddy current locular wall pipe 6 is provided with nozzle 11 along its inwall tangential direction, and the inlet end of the inner chamber of trunnion 7 is a cylindrical section, is the diffuser of platform taper thereafter.

When the utility model uses, it is loaded on the space that needs the cooling cooling, suppose that admission pressure is that 10.5 ℃ of 0.4HPa, temperature tangentially enter with very high speed from nozzle 11 and form free vortex flow in the minor air cell 12, owing to phase mutual friction between the air-flow with different angular speed, outer gas flow angular speed is improved, the angular speed of internal layer air-flow reduces, form forced vortex gradually, meanwhile realized the energy exchange between the ectonexine air-flow, outer gas flow obtains energy, with the friction of tube wall, temperature raises and forms thermal current in addition; Internal layer air-flow degradedness, temperature reduces, and outer field thermal current conducts heat to internal layer, but the energy that loses because of the internal layer air-flow is greater than heat output, so the temperature of internal layer air-flow is still lower, form cold airflow, because action of centrifugal force, air-flow is flowed to orifice plate 3 directions with spirality along tube wall, arrive orifice plate 3 place's constricted flow, thermal current is discharged from orifice plate 3, and the cold airflow of internal layer just is detained to get off, and pressure raises and greater than the atmospheric pressure in the exit of refrigerator pipe 9, so produce inverse axial flow, through trunnion 7,9 outlet rows can reach-24 ℃ cold airflow to the cooling space cold air temperature from refrigerator pipe, thereby reach being located at the instrument in this space, the purpose of apparatus cools cooling.
