It is a new and pollution free way to drive a pulse tube cooler by a thermoacoustic engine without any moving parts and with inert gas as working fluid. Traveling-Standing wave Thermoacoustic Engine including two main parts, that are traveling wave loop and resonance tube, The pulse tube refrigerator including regenerator, pulse and phase modulation organizations. Some experimental studies on Traveling-Standing wave Thermoacoustic Engine were conducted, and structure's effect of pulse tube cooler on its performance was also theoretically simulated.1) The heater, the main cooler and the auxiliary Cooler of Thermoacoustic Engine were designed and processed.2) Following experimental studies were conducted:the system start-up process, the relation between filling pressure and the amplitude, frequency, temperature, pressure ratio, the contrast of different parts'amplitude in the engine when it start, and the relation between the heating temperature and the amplitude of gas.3) A pulse tube refrigerator have been optimized by using REGEN3.3. The parameters such as length of regenerator, cold compression ratio, the cold side mass flow and pressure wave phase, the regenerator packing, were analyzed by the software. |
