Abstract

本发明涉及一种热交换器(1)，包括用于传热流体流过的至少一个管(2)，其连接到至少一个散热翅片(4)。翅片(4)由多孔金属板制成。

Description

具有改进的翅片的热交换器
技术领域
本发明涉及一种热交换器，更特别地涉及一种机械热交换器。
背景技术
热交换器通常包括传热流体将通过其流动的管和连接到这些管的热交换元件。
钎焊热交换器和机械热交换器之间通常根据其制造方法进行区分。
在机械热交换器中，在这种情况下被称为“翅片”的热交换元件以如下方式连接到管。首先，在翅片上形成使管穿过的通孔。这些通孔通常每个都由形成颈部的凸起边缘界定。接下来，翅片基本上彼此平行地设置，并且每个管插入翅片中的一排对准的孔中。最后，通过使膨胀工具穿过这些管的内部来引起管的径向膨胀，以便通过压接机械地结合管和翅片，界定用于管的通孔的颈部然后形成围绕管夹持的套环。
管的该类型的翅片通常由光滑的金属片制成。
发明内容
本发明的目的是要提出一种热交换器，其中热交换性能在器质量受到限制的同时得到改善。
为此目的，本发明的主题是一种热交换器，其包括至少一个用于传热流体流过的管，连接到至少一个散热翅片，其特征在于，所述翅片由多孔(expanded)金属片材制成。
翅片由多孔金属片材制成的事实使得可以在限制热交换器的质量的同时增加空气和翅片之间的热交换，因为翅片的热交换表面面积与光滑的金属片材相比增加，而不另外向其中添加材料。
在对应于机械热交换器的一个特定实施例中，通过将管夹持在形成在翅片中的套环中而将管连接到翅片。
优选地，为了进一步增加空气与翅片之间的热交换，其中热交换器包括一排基本上平行的管，翅片包括至少一排形成百叶片的偏转器，所述排形成在翅片中并介于一排管的两根管之间。
在本发明的一个特定实施例中，多孔金属片材包括每个都呈菱形的整体形状的网孔。
优选地，为了减轻热交换器，多孔金属片材包括铝。
本发明还涉及一种用于制造根据本发明的热交换器的翅片的方法，所述翅片由金属片材形成，其特征在于，
a)将金属片材压缩在分别由压机的两个夹爪承载的两排互补对准的齿之间；
b)两排齿移动半个间距，该间距对应于同一排中的两个齿的连续顶点之间的距离；
c)金属片材横向于成排的齿移动一对应于一个齿的宽度的距离；
d)重复步骤a)；
e)在与步骤b)中的指向相反的指向上将两排齿移动半个间距；
f)重复步骤a)至e)
g)形成使管穿过的通孔。
在一个特定实施例中，该方法包括在所述通孔之间形成百叶片的附加步骤。
附图说明
通过阅读以下仅通过示例并参考附图给出的描述，将更好地理解本发明，在附图中：
-图1是根据本发明的一个特定实施例的热交换器的翅片的局部透视图；
-图2至图7是根据本发明的一个特定实施例的在用于制造翅片的方法中在不同步骤期间用于制造翅片的压机(press)的示意性透视图。
-图8是根据本发明的热交换器的示意图。
具体实施方式
图1示出用于装备机动车辆的机械热交换器1的翅片。
热交换器包括一排基本上平行的管2，传统的传热流体用于流过该管2，以及与这些管2连接的叠置的百叶片4。
管2通过将管夹持在形成在翅片4中的套环6中而连接到翅片4。为此，翅片4设置有供管穿过的通孔8。这些通孔8各自由形成套环6并具有由两个短的半圆形边缘部分连接的两个长边缘部分的边缘界定。每个通孔都具有长形的整体形状，其长的部分在它们的中间略微凹入。
在所描述的例子中，管2各自具有与由通孔描述的形状相对应的形状。管2彼此基本平行地布置，以形成单排。
翅片4具有基本平坦矩形的整体形状，并且以基本上彼此平行且垂直于管2的纵向的方式布置在热交换器1中。
热交换器1允许空气流从上游流向下游，翅片4用于延伸穿过该流。箭头F表示图1中流的行进方向。
为了增加流F和翅片4之间的热交换，热交换器1还包括形成百叶片的成排10的偏转器12，偏转器12形成在每个翅片4中并且没有介于两个管2之间。
翅片4由多孔的金属片材制成，因此偏转器10也是如此。金属片材优选包括铝，例如基本上包括铝的合金。
更具体地说，多孔的金属片材包括各自为菱形的网孔12。
现在将描述根据本发明的用于制造热交换器1的翅片4的方法，所述方法的步骤在图2至图7中示出。
由于翅片4由金属片材16形成，所以该金属片材16首先被压缩在两排18互补的对准齿20之间，互补齿20分别由压机24的两个夹爪22承载。
这例如通过沿图2中的箭头C所示的方向和指向(sense)降低上夹爪22来实现，该压缩如图3所示。
接下来，使两排18的齿移动半个间距，该间距对应于同一排18中的两个齿20的连续顶点之间的距离p。该移动由图4中的箭头P1表示。
然后，金属片材16横向于排18的齿移动一距离d，该距离d对应于一个齿20的宽度。该移动由图5中所示的箭头D表示。
一旦已重复了成排18的齿20之间的压缩步骤，如图5和6所示，两排18的齿20以与箭头P1相反的指向，也就是说在箭头P2的指向上，移动半个间距，如图7所示。
为了获得如图1所示的多孔的金属片材4，重复上述步骤，直到片材16的整个表面已经被压缩，然后实现孔和百叶片。
本发明不限于所给出的实施例，并且进一步的实施例对于本领域技术人员而言将是显而易见的。例如，根据未示出的实施例，管具有圆形横截面并且对应的通孔是圆形的。
