Abstract
This article introduces our recent experimental advances on a 300 Hz pulse tube cooler driven by a thermoacoustic standing-wave engine. After some modifications on the engine, the integral system performance is improved, which leads to a better cooling performance of the high frequency pulse tube cooler compared with that in former reports. Cooling powers of the pulse tube cooler with different operating conditions have been measured in detail for the first time. So far, a lowest no-load temperature of 68 K and a maximum cooling power of 1.16 W at 80 K have been obtained with the mean pressure and the heating power being 4.1 MPa and 1 kW, respectively.
