Experimental Of Mini-refrigerator Driven By A High-frequency Thermoacoustic Engine

The high frequency traveling wave thermoacoustic engine has the advantages of no moving parts, no mechanical friction loss, long life and other advantages. And the driving source can use natural energy such as solar energy, so it has very good research prospect.Thermal acoustic gas mechanism was discussed, and I analyze Benavides vibration mechanics model and make appropriate improvements. Based on the existing experimental conditions to observe how pressure and heating power charge system. Simulate through the thermal acoustic software Deltae to contrast. And find out the differences and then analysis the reasons for deviations. Theoretical analysis of pipe is connected between the thermoacoustic engine and a thermoacoustic refrigerator role, through the simulation and experiments to find out the best length and diameter of the connecting pipe for the device. The theoretical analysis of the thermoacoustic refrigerator condenser tube function, and carries on the simulation analysis. To simulation the refrigerator cold storage and other parts briefly.Analyze the heat exchanger in static sound systems by experiment and simulation by SolidWorks Simulation. Through the experimental phenomena and analysis the reason, obtains the system heating process should be gradually increased, and should not be directly transferred to the high. Compare the performance of the vacuum hood and insulation materials. And compare the performance of the vacuum hood and insulation materials.In this thesis, we improve the refrigeration performance of the thermoacoustic engine through experiments and analyze of thermoacoustic engine under the existing experiment condition. And know how to do experiment better.
