Description

鳍型冷凝器及其制造方法
本发明涉及鳍型冷凝器及其制造方法,特别涉及通过纵向和横向弯曲整体成形的铝管和鳍状物制成的鳍型冷凝器,使换热面积增加而冷凝器的总尺寸减小。
冷凝器是热交换器的一种。它们用于冰箱、空调器等空气调节装置中,通过与压缩机,蒸发器和膨胀阀一起构成致冷循环来进行空气调节。
在致冷器中用有两类基本类型的冷凝器:A)通过在同一长度的预定位置多次弯曲一个长管使得形成多排而制成的冷凝器,所得到的冷凝器的宽度不大于冰箱或空调器的宽度;B)用于形成冷凝器的管在形成“A”冷凝器后又经一个附加步骤而制成的冷凝器,所述附加步骤即各管排横向弯曲多次,所得到的冷凝器是紧凑的,但不再是扁平的。“A”型的冷凝器一般装在冰箱的背后,而“B”型的冷凝器一般设在冰箱的底部,在设置着运行冰箱的各种组件的冰箱的一个室中。
“A”型冷凝器结构较简单,从而容易制造和安装。“A”冷凝器的另一优点是占用最小的空间。然而,这些冷凝器通过自然对流实现热交换,而不同于用一个冷却风扇,冷却效果受限制。而且,因为“A”冷凝器安装在致冷器外,有损致冷器的外观,也存在冷凝器会被损坏的可能性。
如上所述,“B”冷凝器是设计紧凑的。这可使换热面积扩大。而且,这些冷凝器通过冷却风扇的强制对流实现热交换,热交换的效率比“A”型大为提高。“B”型冷凝器也具有装在致冷器内的优点,从外部见不到。由于上述原因,越来越多的致冷器的生产厂家采用“B”型的冷凝器。
见图1A,1B和1C,图中示出上述现有技术的“B”型冷凝器10的制造过程的透视图。
在图1A中,现有技术的冷凝器10的长钢管11,首先在一弯曲机上进行弯曲。即管11在预定位置被弯曲多次,形成多排,冷凝器10的宽度不大于管11的长度。如图所示,弯曲是U型的。管11是钢制的,弯曲半径R根据材料适当地确定。即,过小的弯曲半径会造成一有折皱的管11。
其次,见图1B,在管11的交替侧面上跨管排11垂直焊接钢丝12的多个组G1,G2,G3和G4,即在钢丝12的第一和第二组G1和G2之后,在管的交替侧焊接所有随后的组。钢丝12的作用是增加冷凝器10的传热面积。在钢丝12的组G1,G2,G3和G4之间设置预定的长度间隔。
见图1C,最后的步骤是,被弯曲多次形成排的并具有焊接在交替侧的多组G1,G2,G3和G4钢丝12的管11,在组G1,G2,G3和G4之间横向弯曲,形成紧凑的冷凝器10。
虽在图1B中,管11交替地在侧面焊接钢丝12的组G1,G2,G3和G4,但也可在每一个位置管11的相对侧焊接增加传热面积的两组钢丝12。
如上构成的现有技术冷凝器,因为冷凝器的管是钢制的,较硬的材料制的管的弯曲过程不仅是困难的,而且材料的性质决定弯曲半径必须大。而且,另一个用钢管制造的缺点是尽管需要冷凝器具有高的传热系数,但是钢管造成较低的传热系数。最后,需要在钢管上进行防腐蚀处理,从而增加整个制造过程和成本。
本发明是为了解决上述问题。本发明的目的是提供一种鳍型的冷凝器和一种制造冷凝器的方法,这种冷凝器由能够容易快速制造的材料制成。本发明的另一目的是提供一种鳍型冷凝器和制造这种冷凝器的方法,其中,用于制造冷凝器的材料具有高传热系数,从而提高热交换率。
为达到上述目的,本发明提供一种鳍型冷凝器和制造该冷凝器的方法。所述冷凝器包括一个管,所述管具有分别接受和输出致冷剂的入口和出口;和整体形成在所述管相对侧的用于热传递的鳍状物,所述鳍状物具有一预定宽度,并在一预定长度上从所述管向外伸出。
所述鳍状物一方面可以均匀地(evenly)伸出。另一方面,所述鳍状物可以有弯曲。
所述管纵向再横向弯曲,使所述冷凝器紧凑。而且,在管的预定位置上从管上将鳍状物切削掉形成切削部分,所述管在所述切削部分纵向弯曲。
特别是,所述管和鳍状物由铝材整体制造,加工容易且传热特性好。
在制造所述冷凝器的方法中,所述管是由挤压成形(extrusion)制成的,使所述鳍状物与管一体形成在管的相对例。接着,在管的预定位置从管上切掉鳍状物,在管上形成切削部分,然后所述管在切削部分多次弯曲形成多个排。最后,所述管在多个预定位置横向弯曲。
通过以下结合附图的说明会使本发明的其它目的和优点更明了,其中:
图1A、1B和1C是现有技术的冷凝器制造过程的透视图;
图2是根据本发明的优选实施例的冷凝器制造过程的一步骤的透视图;
图3是图2所示冷凝器制造过程的另一步骤的透视图;
图4A是图2所示管的截面图;
图4B是本发明的另一优选实施例的管的截面图。
首先见图2,本发明优选实施例的冷凝器20由铝制造。用铝易于进行挤压成形(extrusion)。而且铝是轻的优良的传热材料。
在根据本发明的优选实施例中,冷凝器20的长管21首先由挤压成形制成,鳍状物22在管21的相对两侧整体形成,鳍状物22具有预定的宽度,并在预定长度上由管21向外伸出。然后在管的预定位置由管21切削掉鳍状物22,在管21上形成切削部分31。
然后在切削部分31上弯曲多次,形成图2所示的多个排。因此冷凝器鳍状物22的宽度不大于管21的宽度。最好管21进行弯曲的位置选择得使得在弯曲后在鳍状物22之间形成的间隙允许足够的空气在它们之间流动。
然后,见图3,如上所述形成的管21在预定位置横向弯曲多次,形成一紧凑的冷凝器20。
见图4A,在管21上整体形成的鳍状物22,在管21上是均匀地向外伸出的,即鳍状物22是扁平的。
根据如图4B所示的本发明的另一实施例,鳍状物22稍有弯曲。这使空气更顺利地在鳍状物22间流动,从而提高热交换率。
如上结构的冷凝器20连接到压缩机的出口和膨胀阀的入口通道,起热交换器的作用。
在上述结构和制造的优选实施例的冷凝器中,用铝材料制造冷凝器,挤压成形和切削工序容易实施。而且,不需要象现有技术那样向管上焊接钢丝。其结果整个制造过程简单快速。
另外,因为用铝,本发明的冷凝器轻,容易安装,具有较高的传热效率,从而提高热交换率。比钢制的现有技术的冷凝器较容易进行防腐处理。
