“…Matsubara and Miyake [8] and Brito and Peskett [9] proposed the use of passive phase shifters with a moving plug at room temperature. Later, [10,11] introduced the use of an active phase shifter that is controlled and synchronized with the main drive. Active phase shifters give the possibility of achieving the optimum operating conditions of the cold finger.…”

“…The inertia of the gas provides phase shift [7] for the inertance tube-reservoir phase shifter. There are many types of pulse tube cryocoolers and are named based on the phase shifters they use, like double inlet pulse tube coolers [8], tandem [9], active phase control [10], adjustable inertance [11], looped pulse tube cooler [12], etc. An Inertance Pulse Tube Cryocooler (IPTC) uses an inertance tube-reservoir as a phase controller.…”

A performance comparison of a Pulse Tube Cryocooler (PTC) that uses inertance tube- bounce space and inertance tube-reservoir as a phase shifter is conducted using numerical simulations. The initial design cryocoolers were carried out using Sage software. A CFD model was developed using ANSYS Fluent to analyze the Cryocooler performance. The CFD model was used to simulate the effect of different volumes of reservoir and bounce space on Cryocooler performance. The thermal non-equilibrium mode was chosen to consider the effect of temperature difference between solid and fluid temperature difference in porous zones. The numerical model was validated with experiments from referred journal. The simulation results showed a phenomenal increasing trend in cooling capacity up to 400cm3 , and thereafter, a marginal increment in performance with increase in volume. The Stirling cryocooler with inertance tube-bounce space as phase shifter has over performed the cryocooler with inertance tube-reservoir. The COP of cryocooler with 400cm3 bounce volume was found to be 0.042, is 1.38 times higher than that of 200 cm3 and for higher volumes difference in COP was less significant.

“…The above are in reference to the modification of phase shifters. In addition to this, there are methods like modifying the compressor pattern like in case of step piston [5], sharing of compression space between two cryocoolers as in case of Tandem type coolers [6], introducing an additional compressor of lower capacity as in case of Active Phase Control [7]. These techniques are adopted to decrease the size constrain of the cryocooler reservoir volume.…”

Abstract. Pulse tube cryocoolers are used for cooling applications, where very high reliability is required as in space applications. These cryocoolers require a buffer volume depending on the temperature to be maintained and cooling load. A miniature single stage coaxial Inertance Pulse Tube Cryocooler is proposed which operates at 80 K to provide a cooling effect of at least 2 W. In this paper a pulse tube cryocooler, with modified reservoir is suggested, where the reverse fluctuation in compressor case is used instead of a steady pressure in the reservoir to bring about the desired phase shift between the pressure and the mass flow rate in the cold heat exchanger. Therefore, the large reservoir of the cryocooler is replaced by the crank volume of the hermetically sealed linear compressor, and hence the cryocooler is simplified and compact in size. The components of the cryocooler consist of a connecting tube, aftercooler, regenerator, cold heat exchanger, flow straightener, pulse tube, warm heat exchanger, inertance tube and the modified reservoir along with the losses were designed and analyzed. Each part of the cryocooler was analysed using SAGE v11 and verified with ANSYS Fluent. The simulation results clearly show that there is 50% reduction in the reservoir volume for the modified Inertance pulse tube cryocooler.
