Description
开孔波纹高效内翅换热管
技术领域
[0001] 本实用新型涉及的是一种热交换设备中的换热元件，是空分设备中各类压缩机所需级间冷却器或增压膨胀机后冷却器中不同温度介质进行热量交换的设备之主要元器件， 属于换热设备技术领域。
背景技术
[0002] 冷却器是空气分离装置中的一个非常重要的单元设备，特别是对于各类压缩机 (包括空气压缩机、氧气压缩机、氮气压缩机等）或增压膨胀机，为了保证压缩机的正常运行，必须对压缩后的高温气体进行冷却而进入下一级压缩，所以，换热器的冷却效果，直接影响压缩机的效率和使用寿命，也会影响整个空分装置的正常运行。在各类冷却器中，采用光管作为换热元件，是最传统、最普通的结构型式，其特点是结构简单、制造维修方便，但效率低、结构尺寸大、重量较重、制造成本高。
发明内容
[0003] 本实用新型的目的在于克服现有产品在结构设计上的不足，而提供一种体积小、 换热效率高、制造成本低的开孔波纹高效内翅换热管。它是在现有冷却器的基础上，经过改进，将开孔波纹高效内翅换热管替代传统的光管换热管。
[0004] 本实用新型的目的是通过如下技术方案来完成的，它主要由外管、内管组成，所述的外管和内管之间通过钎焊连接有梅花形波纹翅片，并使所述外管和内管相互连接，所述的梅花形波纹翅片上开设有小孔。
[0005] 所述的内管进气端用堵头堵住，外管和内管的中间由22_观个用铜或不锈钢制成的梅花形波纹翅片相连，翅片厚度0. 15-0. 20mm。
[0006] 本实用新型在每个翅片上均开有Φ 3的小孔，开孔位置为：纵向每间隔IOmm—个； 径向为每个翅片的中间部位。
[0007] 当工艺气体进入换热管时，气体的热量通过翅片传递到外管上，达到与管外的冷却水进行热量交换之目的。由于翅片的作用，相当于将整个横截面分成了 25个区间，不仅大大增加了换热面积，也改善了工艺气体的流动状况，提高了换热效率；同时，由于波纹状翅片及翅片上小孔的存在，不仅可以增加工艺气体的湍流度，提高传热系数，而且还可以沟通不同区间之间的联系，减小不同区间之间由于流量分配不均而造成的附加压力损失，降低了气体流动阻力。
[0008] 本实用新型与现有技术相比，具有如下技术效果：其一是增加了单位体积的换热面积，提高了换热效率；其二是缩短了管束的长度，从而减小了整个设备的体积和重量，节约了材料消耗，降低了制造成本。
附图说明
[0009] 图1是本实用新型的横截面图。[0010] 图2是本实用新型的波纹状翅片外观图
[0011] 图3是本实用新型的翅片展开后开孔图。
具体实施方式
[0012] 下面将结合附图对本实用新型作详细的介绍：图1、2、3所示，本实用新型主要由外管1、内管2组成，所述的外管1和内管2之间通过钎焊连接有梅花形波纹翅片3，并使所述外管1和内管2相互连接，所述的梅花形波纹翅片3上开设有小孔4。
[0013] 所述的内管2进气端用堵头堵住，外管1和内管2的中间由22_观个用铜或不锈钢制成的梅花形波纹翅片3相连，翅片厚度0. 15-0. 20mm。在每个翅片3上均开有Φ 3 的小孔4，开孔位置为：纵向每间隔IOmm—个；径向为每个翅片的中间部位。
[0014] 实施例：图1所示，本实用新型主要包括有外管1、内管2和纵向波纹状梅花形翅片3组成，外管直径2，内管直径Φ 14*1，内管2进气端用堵头堵住，中间由25个梅花状的翅片3，翅片厚度0. 18mm，用钎焊法与内、外管连接。内、外管与翅片的材料可以根据工艺需要，采用铜或不锈钢。当工艺气体进入换热管时，气体的热量通过翅片传递到外管上，达到与管外的冷却水进行热量交换之目的。由于翅片的作用，相当于将整个横截面分成了 25个区间，不仅大大增加了换热面积，也改善了工艺气体的流动状况，提高了换热效率。
[0015] 图2所示，每个翅片在纵向都做成波纹状，当工艺气体进入换热管时，由于波纹状翅片的作用，可以改变工艺气体的流动路径，增加湍流度，从而提高换热系数。
[0016] 图3所示，在每个翅片上均开有Φ 3的小孔，开孔位置为：纵向每间隔IOmm—个； 径向为每个翅高h的中间部位。当工艺气体进入换热管时，由于翅片上小孔的存在，每个小孔相当于一个湍流发生器，不仅可以增加工艺气体的湍流度，提高传热系数，而且还可以沟通不同区间之间的联系，减小不同区间之间由于流量分配不均而造成的附加压力损失，降低了气体流动阻力。
