MULTISTAGE PULSE TUBE COOLERS

摘要

Various embodiments are directed to a pulse tube cooler. The pulse tube cooler may comprise a fluid compressor, a first regenerator, a first pulse tube, a first reservoir, a second regenerator, a second pulse tube, and a second reservoir. The first end of the first regenerator may be in fluid communication with the fluid compressor. The cold end of the first pulse tube may be in fluid communication with the second end of the first regenerator. The first reservoir may be in fluid communication with the hot end of the first pulse tube. The first end of the second regenerator may be in fluid communication with the cold end of the first regenerator. The cold end of the second pulse tube may be in fluid communication with the second end of the second regenerator. The cold end of the first pulse tube and the hot end of the second pulse tube may be in fluid communication with one another through the second reservoir.
