    • A pulse tube cryocooler (PTC) includes an etched glass substrate bonded to a glass plate and defining one or multiple stages or layers. The PTC includes a plurality of channels etched into a surface of the substrate to define a heat exchanger, a pulse tube, a cold heat exchanger or cold head, a regenerator and an aftercooler. The bonded substrate and plate encloses the plurality of channels to form capillaries operable for conducting and distributing fluid. The pulse tube is disposed between the cold head and the heat exchanger and the regenerator is disposed between the cold head and the aftercooler. The heat exchanger is connected to a valve or inertance tube which, in turn, is connectable to a buffer tank or reservoir that contains fluid. The aftercooler is connectable to an external compressor operable for oscillating movement, which increases and decreases pressure and temperature within the PTC.
    • 脉冲管低温冷却器(PTC)包括结合到玻璃板并限定一个或多个阶段或多层的经蚀刻的玻璃基板。 PTC包括蚀刻到基板的表面中以限定热交换器,脉冲管,冷热交换器或冷头,再生器和后冷却器的多个通道。 键合衬底和板包围多个通道以形成可操作以导电和分配流体的毛细管。 脉冲管设置在冷头和热交换器之间,再生器设置在冷头和后冷却器之间。 热交换器连接到阀或惯性管,该阀或惯性管又连接到包含流体的缓冲罐或储存器。 后冷却器可连接到可操作以进行摆动运动的外部压缩机,其可增加和减小PTC内的压力和温度。

    • 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.
