摘　　要：介绍了一种采用新型功能材料记忆合金作为调节元件的节流制冷机。从控制机理上讲,该机是利用特种材料记忆合金随温度变化表现出来的形状记忆特性,藉此来对制冷机进行流量调节,从而达到制冷机流量自调的目的。与传统波纹管调节式制冷机相比,该机具有结构简单,装调方便,寿命长,稳定性好的优点。对此制冷机的结构、参数、记忆合金材料及调节机构设计进行了简要介绍与分析。A technical design on self-regulated cryocoolers made by shape memory alloy is proposed in this paper. The cryocoolers flux in this design is determined by the shape memory characteristics of SMA . Compared with the cryocoolers self-regulated with bellows, the new type cryocoolers have merits in simple structure, easy assembly, long life-span and good working stability. Structure, technical parameters, shape memory alloy materials and regulators related to the cryocoolers are introduced.
