技术介绍
制冷机导冷装置是设置于制冷机冷端,将制冷机制取的冷量传导出去的机构,冷量的有效传导是制冷机实现快速高效制冷的关键之一。脉动热管是蛇形的无芯毛细金属管在冷端和热端之间反复弯折形成的回路,毛细管内抽成真空然后充入一定量的工质。工质在蒸发段受热蒸发,使蒸发段压力上升推动工质流向冷凝段,在冷凝段气泡收缩破裂,压力下降回流,通过气柱和液塞的自激励震荡实现潜热和显热的传递。脉动热管作为一种新型热管,克服了常规热管需要吸液芯或者受重力影响的缺点。在一定的条件下,脉动热管可以在任何倾角下运行且对传热性能产生的影响很小,在制冷领域应用前景广阔。有中国专利20150521282.4公开了一种斯特林制冷机结合脉动热管的低温冰箱,包括箱体、自由活塞斯特林制冷机、脉动热管系统、散热系统。其特征为:脉动热管系统包括脉动热管和导冷板管,自由活塞斯特林制冷机的冷端与导冷板管进行换热,使与导冷板管联通的毛细 ...
