Influence of hot end heat exchangers on cascading three pulse tube coolers

Hot end heat exchanger (HHX), an indispensable part in the traditional pulse tube cooler (PTC), rejects the heat generated by dissipation of the acoustic power. The acoustic power, which should have been dissipated at the phase shifters, is delivered to the latter stage cooler in the cascade PTC. Th...

Description
Summary:Hot end heat exchanger (HHX), an indispensable part in the traditional pulse tube cooler (PTC), rejects the heat generated by dissipation of the acoustic power. The acoustic power, which should have been dissipated at the phase shifters, is delivered to the latter stage cooler in the cascade PTC. Therefore, by removing the HHX, power loss could be decreased. Specifically, in our experiment, after removing HHXs, the cooling power obtained by cascading three PTCs could reach 273.2 W at 233 K under the same working condition, which is 23.6 W more than that of the original structure.
