A pulse tube refrigerating system comprising a compressing cavity for compressing a working fluid, a heat radiator connected with the compressing cavity and a regenerator connected with the heat radiator. A pulse tube is provided and connected with the heat radiator through a refrigerating section. The pulse tube is connected through a heat exchanger and a flow regulating valve with an expansion cavity which is operable with a phase difference with respect to the compressing cavity, whereby the working fluid from the compressing cavity is cooled by the heat radiator and passed through the refrigerating section into the pulse tube, the working fluid in the pulse tube being compressed by the working fluid from the refrigerating section to be increased in temperature and passed to the heat exchanger to radiate heat.
A pulse tube refrigerating system comprising compressing means for compressing a working fluid, heat radiating means connected with the compressing means, regenerating means connected with the heat radiating means, pulse tube means, refrigerating means between the heat radiating means and the pulse tube means, heat exchange means connected with the pulse tube means, and expansion means fluidically connected with the heat exchange means by a fluid flow path permitting two directional fluid flow and operable with a phase difference with respect to the compressing means, whereby the working fluid from the compressing means is cooled by the heat radiating means and passed through the refrigerating means into the pulse tube means, the working fluid in the pulse tube means being compressed by the working fluid from the refrigerating means to be increased in temperature and passed to the heat exchange means to radiate heat.
A pulse tube refrigerating system comprising a first refrigerating part including first compressing means for compressing a working fluid, first heat radiating means connected with the first compressing means, first regenerating means connected with the first heat radiating means, first pulse tube means, first refrigerating means between the first heat radiating means and the first pulse tube means, first heat exchange means connected with the first pulse tube means, and first expansion means connected with the first heat exchange means and operable with a phase difference with respect to the first compressing means, and a second refrigerating part including second compressing means for compressing a working fluid, second heat radiating means connected with the second compressing means, second regenerating means connected with the second heat radiating means, second pulse tube means, second refrigerating means between the second heat radiating means and the second pulse tube means, second heat exchange means connected with the second pulse tube means, and second expansion means connected with the second heat exchange means and operable with a phase difference with respect to the second compressing means, said first compressing means being operated with a phase difference with respect to said second compressing means.
