Problems solved by technology

The refrigeration efficiency of these refrigerators is high, but because the structure is generally more complicated, there are many rotating parts inside, in order to prevent gas mixing and leakage before and after refrigeration, generally all are equipped with various forms of dynamic seals and outer seals, this The bearing capacity of this type of machine is greatly reduced

Embodiment Construction

[0049] A multi-tube jet oscillation refrigerator mainly consists of a body (3), an oscillation receiving tube (1), a core (6), an acoustic oscillator (8), a jet nozzle (9) and the like.

[0050] The body (3) is processed from a metal plate with a size of 100-120mm in thickness, and according to the size of the processing capacity, 3-15 metal plates with a length of 500-600mm, a width of 6-10mm, and a depth of The diameter is 60-80mm, and the cross-section is a rectangular jet flow channel (4). There is a stepped platform processed in the flow channel, which is specially used for positioning the inserts of the welding package flow channel, and to ensure the size of the flow channel. The overall distribution of the runners is divergent, the distance between the runners near the end of the core (6) is tapered, and the distance between the runners at the end of the injection area is generally 2mm, and the runners are sharply narrowed. This will help the jet nozzle (9) to fully unh...

Abstract

Cold-heat effect of shock oscillation tube combined with jet oscillation technique is adopted in the invention to reach purpose of refrigeration. The machine is composed of main machine body, static ejector nozzle, oscillation receiving tube and acoustic oscillator etc. Under combined action of gas distributor and acoustic oscillator, gas is jetted in periodic deflexion and periodic intermittent into receiving tubes around to generate flow in high frequency oscillation. Further, under interaction effect and inference of series of wave including shock wave, compression wave and expansion wave, the machine completes unsteady expanding work and energy conversion so as to realize refrigeration through gas. Features are simple structure adjustable continuous flow, suitable to work medium in phases of gas and liquid.

Description

technical field [0001] The invention belongs to the technical field of jet flow engineering and expansion refrigeration of pressurized gas. Background technique [0002] Gas wave refrigerators and heat separators (Chinese patents 87101903.5, 89213744.4, 96115022.X, etc.) all belong to one-time and multiple unsteady expansion refrigeration, and all rely on motor drive or use the pressure difference of the gas to drive the gas distributor to automatically Rotation, at a certain rotation speed, the medium gas is sequentially jetted to the receiving tubes that are closed at each end of the ring, so that the resident gas in the tube does unsteady expansion work. The turbo expander realizes refrigeration at high speed. The refrigeration efficiency of these refrigerators is high, but because the structure is generally more complex, there are many rotating parts inside, in order to prevent gas mixing and leakage before and after refrigeration, generally all are equipped with various...
