摘　　要：为研究微型混合工质节流制冷器的降温性能,搭建了微型压缩机驱动微型混合工质节流制冷器的制冷系统,并得到了初步实验研究结果。采用Aspen微型压缩机驱动微型J-T节流制冷器,应用混合制冷剂实现深度制冷。微型J-T节流制冷器采用微小通径的不锈钢毛细管制作,其通道特征尺寸为0.3mm。初步实验表明,微型J-T节流制冷器达到了180K温区。由于采用微型压缩机驱动,系统结构紧凑,可在便携生物储存设备、低温医疗以及电子器件冷却等领域应用。The cool-down performance of a miniature mixed refrigerant J-T refrigerator was experimentally investigated. A miniature mixed refrigerant J-T refrigerator driven by an Aspen mini-compressor was developed, and preliminary test results were presented. The miniature J-T cryocooler was constructed with stainless steel capillary tubes with specific inner diameter of 0.3mm. By using muhicomponent mixed refrigerant, the miniature J-T refrigerator can reach no-load temperature of 18OK. Driven by the mitli-compressor, such miniature J-T cryocoolers have good perspective in such applications as mobile biomaterials preservation, cryosurgery and electronic devices cooling, etc.
