ABSTRACT:
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.
