The concrete operation principle of air wave refrigerating device provided by the invention is following;
(1) the incident stage: driving gas gets in the casing 1 from driving gas inlet 11; Driving gas promotes impeller 9 and rotates; Impeller 9 drives rotor 5 and rotates (driving gas can be the sub-fraction of incoming flow gases at high pressure shunting, also can be other source of the gas) together; After rotor 5 rotated, the incoming flow gases at high pressure quickened through pressurized gas inlet 21, spray into successively in the oscillating tube 6 on the rotor 5 with the velocity of sound or supersonic speed;
(2) the compression refrigeration stage: the high-speed gas that is accelerated through pressurized gas inlet 21 is to the original gas compressed action in the oscillating tube 6; Because spraying into the gas of oscillating tube 6 from pressurized gas inlet 21 is velocities of sound or supersonic; So the gas in spraying into oscillating tube 6 can produce shock wave when running into the static gas that has existed in the oscillating tube 6; Original gas in high-speed gas that shock wave sprays into just as an invisible piston cuts off and the oscillating tube 6; And the gas in the oscillating tube 6 compressed (the compressed high temperature medium pressure gas that becomes); Make that original gas temperature and pressure all raise in the oscillating tube 6, then through pressing heat outlet 31 to get into heat exchangers 8 heat radiations in the high temperature and becoming the normal temperature medium pressure gas; The high-speed gas that sprays into from pressurized gas inlet 21 simultaneously is because to original gas acting in the oscillating tube 6, self-energy is consumed, so become low-temp low-pressure gas, stays in the oscillating tube 6;
(3) exhaust phase: stay the low-temp low-pressure cold air in the oscillating tube 6; Rotation along with rotor 5; Can be communicated with low-temp low-pressure cold air outlet 22 and normal temperature medium pressure gas inlet 32; Normal temperature medium pressure gas in the heat exchanger 8 returns through normal temperature medium pressure gas inlet 32 and gets in the oscillating tube 6, ejects the low-temp low-pressure cold air in the oscillating tube 6 and stay in the oscillating tube 6, and low-temp low-pressure cold air is discharged through low-temp low-pressure cold air outlet 22; Along with the rotation of rotor 4, press heat outlet 31 to be communicated with in oscillating tube 6 and pressurized gas inlet 21 and the high temperature, stay normal temperature medium pressure gas in the oscillating tube 6 again by high-speed gas compression from pressurized gas inlet 21 incidents, get into next circulation, reciprocation cycle like this.
In sum; Because pressurized gas inlet 21 of the present invention is surrounded with the movable plate 212 that can in open trough 211, move up and down by open trough 211 and forms; Movable plate 212 is driven by executing agency 7 and in open trough 211, moves up and down; Thereby realized regulating the purpose of pressurized gas inlet 21 sizes, improved refrigerating efficiency, solved the problem that the jet size on the gas distributor of existing air wave refrigerating device can't be regulated.
In addition; The present invention adopts driving gas to get in the casing 1 from driving gas inlet 11, and driving gas promotes impeller 9 and rotates, and impeller 9 drives rotor 5 and rotates together; Therefore; Rotating shaft 4 of the present invention need not stretch out that casing 1 is outer to be connected with motor and to be rotated by motor-driven, sealing property significantly improves, and has significantly reduced the amount of leakage of the interior gases at high pressure of casing 1; Reduced the cold energy loss, the interior high pressure gas of casing that has solved existing air wave refrigerating device is known from experience the problem of going out from the clearance leakage between rotating shaft and the casing.Simultaneously, be connected with motor, therefore, reduced the volume of whole air wave refrigerating device, convenient transportation, installation and operation because rotating shaft 4 of the present invention need not be stretched out outside the casing 1.
Moreover the present invention also can adopt the structure of foregoing adjusting pressurized gas inlet 21 sizes to regulate the size of pressing heat outlet 31 in the high temperature, also belongs to protection scope of the present invention.
The above is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also are regarded as protection scope of the present invention.
