Description

热交换器，特别是用于汽车的增压空气冷却器
技术领域
本发明涉及一种热交换器，特别是用于汽车的增压空气冷却器。
背景技术
已知的热交换器由一个热交换器芯体(或被称为管系)和布置在两侧的集流箱组成，所述集流箱用于热交换介质如冷却液或增压空气的进出或汇集和分配。热交换器芯体由平行布置的管如扁平管以及用来加大管外侧的传热面并被周围空气掠过的翅片组成。在扁平管上使用的是波纹翅片，它们与管钎接。为了提高传热效率，在管、特别是扁平管的内侧布置了所谓的内波纹翅片或湍流发生机构，它们同样与管钎接。通过这种方式，使热交换器芯体具有良好的稳定性和高内部抗压强度。管的管端接入到管板中，而管板则是集流箱的一部分或与集流箱连接。管板带有通孔，管端***到孔中并钎接。类似的热交换器曾在DE-A 198 57435中公开。
按照热交换器的功率，可采用单列或多列***(热交换器芯体)，即在冷却空气的流动方向上，布置着一个列或多个前后排列、之间带有间距的列。在特别是风冷的增压空气冷却器上，在冷却汽车内燃机的燃烧用空气时，在效率较低的情况下采用单列的管系，在效率较高的情况下采用双列的管系，后者的结构深度超过约70mm。但双列***具有若干缺点：它们的制造成本较高、效率较低。在制造时，两个管列必须与连续的翅片紧束在一起，然后***到管板上的两列通孔中。出于生产方面的考虑，管板中的通孔之间在深度方向上必须有一个最小间距，这个最小间距也规定了管系中的管列之间的间距。这个间距提高了冷却空气侧的压降，加大了热交换器的总深度。
发明内容
本发明的目的是提供一种本文开头所述的热交换器，它的制造成本较低并且热动力性能得到改善。
这个目的是由具有以下特征的热交换器实现的。按照本发明，热交换器芯体只具有一列扁平管，其深度T大于70mm且小于120mm。在冷却空气的流动方向上具有这种深度的单管列热交换器、特别是增压空气冷却器，在制造和成本以及效率方面具有优势。而在这种深度上，已知的热交换器、特别是增压空气冷却器采用的是双管列结构。按照本发明的***则与之不同，只需要一列扁平管以及冷却空气侧的波纹翅片和增压空气侧的内波纹翅片。这样一种***要比双管列***更容易束在一起(kassettieren)。此外，管板只具有一列通孔，也就是说，不再有冷却空气流动方向上的通孔之间以及管列之间的间距。这样还带来另外的优点，即总深度较小以及在一次侧和二次侧的压降较少。
按照本发明的一个优选实施形式，扁平管的深度在70到100mm的范围内，优选在80到90mm的范围内。
按照本发明的另一个实施形式，扁平管的深度在90到120mm的范围内，优选在90到100mm的范围内。
按照本发明的一个优选实施形式，扁平管的净宽为3到10mm，优选为5到10mm，特别优选为6到8mm，其中，最佳的净宽为7mm。扁平管的这样一种横断面将会提高热交换器的效率。
按照本发明的另一个优选实施形式，扁平管中布置着内波纹翅片或嵌入式湍流元件，它们与扁平管钎接。通过这种方式，改善了传热，提高了扁平管的内部抗压强度，这对于较大的深度尤为必要。
附图说明
下面通过实施例和附图对本发明进行详细说明。
附图为本发明热交换器芯体1的截面图。
具体实施方式
本发明的唯一附图是热交换器芯体1的截面图，所述芯体由一(数词)列扁平管2和布置在扁平管之间的波纹翅片3组成。扁平管2和波纹翅片3是图未示的增压空气冷却器的一部分，这个增压空气冷却器通过外界空气(冷却空气)对图未示的、被增压的汽车内燃机的空气(增压空气)进行冷却。增压空气在垂直于图示平面的扁平管2中穿流，而周围空气或冷却空气则沿箭头L所示方向在扁平管2之间流动并掠过波纹翅片3，所述翅片带有用于改善传热的鳃片4。在扁平管2的内部布置着内波纹翅片5，从横断面看它们将扁平管2分成多个室，并与扁平管2在其内侧钎接。与之相反，波纹翅片4则与扁平管2的外侧钎接。就这一点而言，从扁平管2的内侧到它的外侧形成了良好的导热。如前面的现有技术所述，扁平管2固定在图未示的管板上的通孔之中并与之钎接。在管板上安置着图未示的集流箱，即所谓的空气箱。
总深度T，即扁平管2和波纹翅片3在气流方向L上的延伸用T表示。虽然尺寸T对扁平管2非常重要，但波纹翅片3却可以具有一个与之相比较小或较大的尺寸，也就是说，它们相对于扁平管2的窄侧凹入或凸出。扁平管2的净宽由尺寸H表示。在扁平管2的一个实施形式中，尺寸T在一个较窄的范围80到90mm之内，也可以在一个较宽的范围70到100mm之内，还可以在一个更宽的范围70到120mm之内。扁平管2优选由铝板制成，并在窄侧沿纵向焊接。波纹翅片3(冷却空气翅片)和内波纹翅片5(增压空气翅片)由薄铝板制成，并与扁平管2钎接。这样就形成一个紧凑的、耐压的热交换器芯体1。
