Abstract:Pulse tube refrigerator with 1kW cooling capacity is one of the key technology for HTC super conductor cable, LNG re-condensing, and others. High power pulse tube refrigerator meets a lot of technology difficult, such as matching of the linear compressor and cold head and design of the regenerator whose length diameter ratio is small. In this paper, a 1kW pulse tube refrigerator was designed with numerical simulation based on a small pulse tube refrigerator whose theoretical efficiency is over 15%.
