Self-excited microjet control multi-tube oscillator

The invention belongs to the technical field of jet control engineering refrigeration of pressure gas, and relates to a self-excited microjet control multi-tube oscillator. The self-excited microjet control multi-tube oscillator is special equipment of gas jet control like a refrigeration device, a same-gas-source fluid separated from main jet and equal to the total pressure of the main jet is intruded into a self-excited oscillating cavity from the outside, self-excited oscillating is carried out to generate periodic microjet, the main jet is pushed and pressed at the wall attaching side froma perpendicular exciting opening, the manner of pushing and pulling the main jet is used for achieving main jet oscillating, the main pressure is increased and continues, continuous oscillating is finally achieved, and the problem that energy consumption is high due to self-excited jet oscillating is solved. The oscillator has the advantages of being simple in structure, convenient to operate andmaintain and the like, ex
