| Abstract: | The heater, which is the key part of a thermoacoustic engine is improved. With t he new heater, the self-made traveling-wave thermoacoustic engine was used to drive a single stage orifice pulse tube cooler. Charged with helium of 2.2 MPa, the lowest refrigeration temperature of 110K is obtained. Based on the experime ntal results, the optimum match between the pulse tube cooler and the thermoac oustic engine was discussed and the practical solution was proposed to obtain be tter cooling performance. |
