Description

冷却装置
技术领域
本实用新型涉及一种用于带有外壳的内燃机的冷却装置，尤其是废气冷却装置，在该外壳中设有至少一个热传递单元，其中，外壳具有这样设计的冷却剂入口和冷却剂出口，使得冷却剂环流过热传递单元，其中，热传递单元具有流体入口和流体出口，所述流体入口和流体出口通过流体通道相互连通，其中，流体通道具有这样设计的导热肋，使得在流体流过流体通道时在流体和导热肋之间发生热交换。 
背景技术
这种冷却装置是公知的并且在很多申请中有记载。在此，尤其已知这样的热交换器，这些热交换器被位于外壳和热交换器之间的冷却剂环绕流过，并且具有指向内部的，也就是指向流体通道的导热肋。这些导热肋明显改善了冷却剂和待冷却的流体之间的热传递。这些肋相比不带肋的设计方案尤其延长了流体通道中的滞留时间并且增大了速滞压力。在一种用作内燃机废气热交换器的热交换器中也可以使用这种肋，以进一步防止废气流过的通道被布满烟炱或形成积炭层。 
因此，在US 6,173,758B1中记载了一种热交换器，其具有大量伸入流体通道中的导热肋。现在为了延长流体通道并因此延长流体在热交换器中的滞留时间，以达到热交换器更好的效率，该文献记载了一种将流体通道分成两个被U型地相继流过的流体通道部段的隔板。 
这种设计方案的缺点是，必须分别针对发动机特有的需求开发一种特定的冷却装置。不能在制造技术上简单地使冷却装置与所需的冷却功率相适应。 
发明内容
因此，本实用新型所要解决的技术问题是，创造一种克服上述缺点的冷却装置。 
该技术问题通过一种用于带有外壳的内燃机的冷却装置，尤其是废气冷却装置解决，在所述外壳中设有至少一个热传递单元，其中，所述外壳具有这样设置的冷却剂入口和冷却剂出口，使得冷却剂环流过所述热传递单元，其中，所述热传递单元具有流体入口和流体出口，所述流体入口和流体出口通过一流体通道相互连通，其中，所述流体通道具有这样设计的导热肋，使得在流体流过所述流体通道时，在所述流体和所述导热肋之间发生热交换。按本发明，在热传递单元中设置至少一个导板，其中，导板分别形成流体通道部段平行于导热肋延伸的侧壁。冷却装置可以以这种方式借助导板与不同的需求相适应。因此，可以通过改变导板数量使流体通道增加一倍、两倍、或三倍。通过选择导板的布置也可以改变各流体通道部段的流量。 
在一种优选的设计方案中，在导热肋和热传递单元之间夹紧有导板。为了进一步提高效率，在外壳和热传递单元之间设置一个用于冷却剂流的螺栓状的导向连接件。由此也确保冷却剂在冷却装置中的滞留时间足够长。在此，导向连接件基本上由成型件，例如铝或塑料弓形件构成，其中，成型件夹紧在热传递单元上。 
附图说明
在附图中示出并且下面描述冷却装置按本实用新型的设计方案。在附图中： 
图1以剖面图示出了按本实用新型的冷却装置的俯视图， 
图2是带有打开的外壳和封闭的热传递单元的冷却装置的俯视图。 
具体实施方式
附图中示出的、优选作为废气冷却装置应用在汽车中的冷却装置包括外壳2，在该外壳2中设有热传递单元3。在装配之后，在外壳2和热传递单元3之间形成一个由冷却剂流过的通道(此处尤其参见图2)。此外，外壳2具有流体入口4和流体出口5，它们在该实施形式中称作废气入口4和废气出口5。在废气入口4和废气出口5之间形成一流体通道，在此是废气通道6，该废气通道6在该实施形式中分成三个废气通道段7、8和9。热传递单元3以公知的方式具有导热肋10，该导热肋10这样伸入废气通道中，使得在流过废气通道6时，在废气和导热肋10之间发生热交换。 
在此，各废气通道段由夹紧在导热肋10和热传递单元3之间的导板11、12构成。由此，可以按特别简单和廉价的方式使热传递单元与内燃机冷却效率方面的各种要求相适应。 
现在图2示出了按本实用新型的、带有开口的外壳2和封闭的热传递单元3的冷却装置1的俯视图。在外壳中设有冷却剂入口和冷却剂出口，在当前的视图中，冷却剂出口和入口分别在位置13和14处示出。在外壳2和热传递单元3之间设有一个螺栓状的导向连接件15，其保证冷却剂全面地环流过热传递单元。冷却剂从冷却剂入口13到冷却剂出口14的基本通流方向与废气从废气入口4到废气出口5的基本通流方向相反，由此，可以再次提高冷却装置的效率。导向连接件15基本上是由成型件，例如铝或塑料弓形件构成。在此，成型件16借助夹紧器件17夹紧在热传导单元上，并且可以与未进一步示出的焊缝共同作用，以形成导向连接件15。
