摘要
针对波纹管式自调节流制冷器普遍存在稳定性差的问题,通过对此类制冷器最核心的部件——波纹管自调机构的受力分析,对制冷器的预留位移量这个核心参数进行优化设计,增强了制冷器的自调能力,从设计上避免制冷器不自调或流量变化现象的发生,改善了长期困扰自调式制冷器的间歇性喷液现象,提高了制冷器的稳定性,并通过实验得到了论证。
Aiming at the problem of poor stability of self-regulated crycooler with bellows, through the force analysis of self-regulated structure of bellows, the reserved displacement is optimally designed which is the core components of the self-regulated crycooler with bellows. Self-regulation ability of the crycooler is enhanced. Mis-function of self-regula- ting and flow rate changing of the crycooler are avoided by design. The phenomenon of intermittent hydrojet of the self-regulated crycooler is improved. The stability of this crycooler is improved observably, which is verified through experiments.
