Description

一种用于剪切变稀型流体的冷凝管
技术领域
本发明涉及冷凝管,特别涉及触变性流体中的剪切变稀型的流体的冷凝管。
背景技术
冷凝管包括外管和内管,是实现流体冷却的实验设备,也广泛的应用于工业及家用的冷却设备中。
对于触变性的流体,高分子在流动时各液层间总存在一定的速度梯度,细而长的大分子若同时穿过几个流速不等的液层时,同一个大分子的各个部分就要以不同速度前进,这种情况显然是不能持久的。因此,在流动时,每个长链分子总是力图使自己全部进入同一流速的流层。不同流速液层的平行分布就导致了大分子在流动方向上的取向。这种现象犹如河流中随同流水一起流动的绳子(细而长)一样,它们总是自然地顺着水流方向纵向排列的,聚合物在流动过程中随剪切速率或剪切应力的增加,由于分子的取向使黏度降低,我们称之为剪切变稀型。因此,流速及对流体的剪切形成切应力可使得流体变稀,易于流动,不会在内管中产生迟滞从而增加流体推动力的问题。
发明内容
本发明所要解决的技术问题是提供一种适合剪切变稀型的流体的冷凝管,为此,本发明采用以下技术方案:
一种实施方式,它包括外管和内管,所述内管供需冷却流体经过,所述外管填充冷媒,所述内管设有:
剪切部件,被配设为分布在内管壁上的、剪切流体的薄片。
进一步的,所述薄片为分布在内管壁上的朝向内管中心的方形片状物。
方形片状物的一种实施例是所述方形片状物可在内管的中心接触也可不接触;另一种实施例是所述方形片状物从内管的入口一直延伸至出口;再一种实施例是所述方形片状物的长度小于内管的长度,可间隔的设置在内管壁上。
另一种实施方式,所述薄片为设置在内管壁上的延内管壁曲线的片状物。
进一步的,所述片状物从内管的入口一直延伸至出口。
进一步的,所述片状物的长度小于内管的长度,其间隔的设置在内管壁上。
由于采用了本发明的技术方案,本发明的内管专业为剪切变稀型的流体设计。在保证流体的流动性的前提下,设计了可切断流体的剪切部件,不会在内管中产生因流体粘度增加而迟滞。
