【 摘 要 】

Thermoacoustic refrigerator has emerged as one of new alternative ways of cooling. The use of this technology which converts sound energy to heat energy has not been popular despite its environmentally friendly and simple construction. A laboratory scale thermoacoustic cooling device has been constructed to conduct experiments on three different shapes of resonators that results in temperature difference occurring at its stack ends. Geometry of the device parts is one of the parameter that holds importance to its characteristic. The device applied a different shape of resonator for each experiment and record temperature data at stacks ends. The experiments were conducted with variations in resonator which are square tube, cylinder tube and tapered tube. The material of resonator is acrylic and its inner volume remains unchanged.
