介绍了一种应用于红外焦平面探测器组件上的自调式节流制冷器,该制冷器为锥形结构,采用了一种新型自调方式,与传统的波纹管型自调式节流制冷器相比,具有制冷速度快、结构简单、成本低廉、装调方便等优点;文中还对该制冷器自调机构的工作原理进行了简单的介绍和分析,并对该型制冷器进行了性能测试.%This paper introduces a kind of the self-regulated J-T cryocoolers applied to infrared focal plane detector components. The cryeooler with tapered structure, adopts a kind of new self-regulated way. And the crycoolers compared with the traditional self-regulated J-T cryocoolers with bellows have some advantages,such as the cooling speed, simple structure, low cost, convenient assembly and so on. The paper also analyses the working principle of this kind of self-regulated J-T cryocooler, and we have performance test of these coolers.
