    "abstract": "The design of a Double Inlet Pulse Tube Refrigerator is investigated by means\nof an analogy with an electric circuit. The results obtained with the electric\nscheme are compared with both those of the thermodynamic model (Part A) and\nexperiments. The basic formulation of equivalent electronic components is\ndiscussed and a few improvements are proposed to adjust the theoretical\nexpressions of the electrical impedances of capillaries and regenerator in\norder to consider additional effects such pressure drops due to geometrical\nsingularities at different internal flow regimes. A simplified formulation for\nthe regenerator inefficiency is deduced from considerations on its harmonic\nfunctioning. The main purpose of this analysis considers especially the design\nof miniature cryocoolers dedicated to electronic applications. These models are\napplied to a commercial miniature refrigerator. A discussion of their relevance\nis achieved and a few suggestions on the refrigerator design are proposed to\nimprove the cooling production.",
