Abstract

本发明涉及一种热交换器,特别是增压空气/冷却液冷却器(1),它带有多个盘(2),两个相邻的盘确定一个被热交换介质穿流的中间空隙;所述热交换器还包括各盘(2)共有的一个热交换介质进口(9)和一个热交换介质出口(11)。为热交换介质进口和/或热交换介质出口(9,11)设置了至少两个热交换介质通道(5,6)。

Description

热交换器,特别是增压空气/冷却液冷却器
技术领域
本发明涉及一种盘式结构的热交换器,特别是增压空气/冷却液冷却器。
背景技术
在传统的盘式结构增压空气/冷却液冷却器中,增压空气和冷却液通过一个唯一的接管进入到冷却液盘中。但这种增压空气/冷却液散热器的冷却效率还不能令人满意。
发明内容
本发明的目的是提供一种改善了的热交换器。
这一目的是由具有以下述特征的热交换器实现的。进一步的特征提供了具有优点的实施形式。
按照本发明,一种盘式结构的热交换器,特别是增压空气/冷却液冷却器,带有多个盘,其中,两个相邻的盘确定一个被热交换介质穿流的中间空隙;它还带有各盘共有的一个热交换介质进口和一个热交换介质出口,这里,为热交换介质进口和/或热交换介质出口设置了至少两个热交换介质通道。在这里,热交换介质通道优选地由各盘中相互完全对中的开口形成。
增压空气/冷却液冷却器也可由任一种具有相同结构的其它热交换器代替,如油冷却器。这种按照本发明形成的热交换器,可以使热交换介质在构成热交换器的各盘中与热交换有关的区域内均匀分布。通过流体的这种均匀分布,减少了用于临界区域的热交换器的沸腾问题。
在涉及热交换介质通道时,该盘相对于其纵轴成轴对称,这样将会促进热交换介质的分布。如果盘另外还相对于其横轴成轴对称,将会使装配得到简化。
本发明优选地设置一个唯一的热交换介质进口和/或一个唯一的热交换介质出口,所述进口或出口带有一个分流装置或汇流装置。由于流体分布得到改善,从而促进了热交换,因此这种布置可以使结构相对简化。
分流装置和/或汇流装置优选为圆弧形,这样就可以在将各盘连接在一起的螺栓等的周围形成一个节省空间的结构。
从流动方向看,在分流装置和/或回流装置区域优选地设有一个30°到90°的弯折部,其中,分流装置或汇流装置的叉形部分与盘平行。
通过分流装置过渡成为两个热交换介质通道的热交换介质进口优选地平行于热交换介质通道,而分流装置的两个部分则优选地布置在与热交换介质通道垂直的平面内。两个热交换介质通道通过汇流装置过渡成为热交换介质出口,它优选地平行于热交换介质通道,而分流装置的两个部分则优选地布置在与热交换介质通道垂直的平面内。这就使热交换器具有一个紧凑、节省空间的结构。介质也可以通过两个单独、分离的管输送,这两个管通过一个Y形的连接件相互连接。
这种热交换器优选地作为增压空气/冷却液冷却器,用来冷却增压空气。这里优选地采用水和乙二醇(Glykol)的混合物作为热交换介质(冷却液)。
附图说明
下面通过附图和实施例对本发明进行详细说明。其中,
图1是按照本发明实施例的盘式结构增压空气/冷却液冷却器的立体爆炸示意图,
图2是图1中所示的增压空气/冷却液冷却器的立体图,
图3是图1中所示的增压空气/冷却液冷却器沿图4中的III-III线的截面图,
图4是图1中所示的增压空气/冷却液冷却器沿图3中的IV-IV线的截面图。
具体实施方式
如图所示,增压空气/冷却液冷却器1作为增压空气和冷却液之间的热交换器,具有多个相互叠置的冷却液盘2。在这里,每个冷却液盘2中分别设有两个流入孔3和两个流出孔4,作为热交换介质的冷却液通过它们进入到冷却液盘2中间的空隙或从那里流出。流动方向在图中用箭头表示。冷却液在通过流入孔3进入后,就在冷却液盘2中间空隙的整个宽度内扩散,并均匀地流向流出孔4(见图3),这样就使中间空隙在流入孔3和流出孔4之问的整个长度和宽度都被穿流,从而可以使在冷却液盘2之间穿过增压空气/冷却液冷却器1的、待冷却的增压空气的传热实现优化。
相互叠置的冷却液盘2中的孔3和4形成冷却液通道5和6。为此,孔3和4所在的区域相应升高,这样就可以获得足够的中间空隙,以便增压空气能在冷却液盘2之间穿流并被冷却。
从冷却液的流动方向看,两个冷却液通道5布置在分流装置7处,它具有一个圆弧形的叉形件8和和一个布置在圆弧形中心、并与冷却液通道5平行的冷却液进口9。这样,通过冷却液进口9进入的冷却液被均匀地分配到两个冷却液通道5中。
进口的结构与出口相同。两个冷却液通道6的终点是汇流装置10,它的结构与分流装置7相同,并带有一个冷却液出口11。
