Description
本发明涉及热交换器，更具体地说，是一种液冷式两相热交换器，其中的流体与一种液体进行热交换后，该流体可以从气态变为液态，或者从液态变为气态。
近几十年来，人们对内燃机给环境带来的影响越来越关心。各种各样的车辆中绝大多数广泛采用这种发动机。这些关注中有些是关于节约能源，而另一些是关于废气排放。
需要解决的许多问题和解决问题的方法是相互作用的。例如，提高车辆动力消耗系统的效率，就减少了燃料消耗，这既满足了节约能源的要求，也满足了减少废气排放的要求。
均属于Lukas等人的美国专利号为5,408,843和5,520,015的两项专利，分别于1995年4月25日、1996年5月28日公告。这两项专利公开了一种车辆冷却系统，能够用于解决前述的问题。这两项专利都由最先应用的受让人拥有，公开的所有内容都参考在内。
在前面提到的专利所公开的系统中，在车辆的空调系统内应用的是液冷式的冷凝器。这种冷凝器把制冷剂从气态冷凝到液态，然后再循环到一个蒸发器，在此蒸发以为车辆的某些部分提供制冷。在Lukas公开的专利中，蒸发器是气冷式的，但是，在某些情况下，特别是希望制冷剂管道具有最小长度以减少制冷剂量及需要制冷的位置距离空调系统较远时，会希望在需要制冷的位置提供冷却液体，该液体由位于靠近空调系统其他部件的一个蒸发器来冷却。
本发明提供一种新型、改进的液冷式两相热交换器，适用于诸如在Lukas的专利所公开的及其它需要由液态转变为气态、或由气态转变为液态的一种流体与一种液体之间进行热交换系统中。
本发明的主要目的是提供一种新型、改进的液冷式两相热交换器。
更具体地说，本发明的一个目的是提供一种液冷式两相热交换器，该交换器包括若干个相互间隔、并排设置的板状扁平管。端板位于板状扁平管的端部，在密封关系中，承受力相同。液体容器固定在各个端板上，其中的一个液体容器安装有一个液体输入口。还有一个液体容器安装有液体输出口。还包括多个并排设置的扁平蛇形管，每个蛇形管都有端部，在蛇形管的端部之间有许多大致平行的直管。安装有一对大致平行的集流管，容纳并密封蛇形管对应的端部。每个板状扁平管以热交换的关系嵌套在蛇形管相邻的两个直管之间。每个蛇形管位于两个端板之间。
在一最佳实施例中，板状管和蛇形管形成一个压缩的堆叠管组。
在更优先的发明中，每一个蛇形管都有一个圆拱形管以连续的方式把两个相临的直管连接起来，当压缩到堆叠管组中时，圆管成为球根形。
在实施例中，每个板状管有多个内部薄板条以确定多个流动路径。直管最好与流动路径垂直。
在另一实施例中，一对集流管为扁平状。
图1是根据本发明的液冷式两相热交换器的一个侧视图；
图2是热交换器的一个平面图；
图3是沿图1中3-3线所做的一个剖视图。
图4是热交换器的一个后视图；
图5是用于本发明中的蛇形管的一个正视图；
图6是用于本发明中的板状扁平管的一个剖视图。
根据本发明制造的液冷式两相热交换器的一个典型实施例如附图所示。它可以根据需要用作液冷式冷凝器或蒸发器，当做为热交换器用作其他用途时，同样可以发现其功效。
参考图1和图2，热交换器包括两个相互间隔开、相对的端板10，12。每个端板10，12安装有一个有关的容器14，16。容器14包括一个液体输入口18，而容器16包括一个液体输出口20。但是，应当认识到，在某些情况下，输入口18和输出口20可以由两者之间的直接液体流动连接到同一个液体容器，输入口和输出口之间由一个内部隔板隔开(图中未示出)。也就是说，所示的实施例是液体一侧的单通路热交换器，如果需要，也可以是多通路。
在图3中，可以最清楚地看到多个板状扁平管22在端板10和12之间延伸。在图2中可以看到，管22的端部通过端板10和12中的槽(未示出)，然后用例如铜焊等方法密封在端板10和12上。由此，每个容器14和16的内部与管22进行液体交换。
在图2和图3中还可以看到，板状管22一般相互平行并彼此间隔设置。
根据本发明，在板状管22的一侧，一对大致为圆柱形的集流管/容器30，32通常以相互间隔并相互平行的关系延伸。集流管/容器30，32包括狭槽34，用于安装多个蛇形管40的两个相对的端部36、38。蛇形管40通常为挤制的、多端口管，每个蛇形管有多个水力直径相当小的内部流动路径，即水压直径约为0.07英寸。端部34以一通常方式，例如铜焊分别与集流管/容器30，32焊接密封。
在每个蛇形管40的端部34之间，有多个直管42。相临的直管42由圆拱形管44连接，圆拱形管44分布在板状扁平管22的外侧。
参照图5，圆拱形管44在直管42之间为蛇形管40提供180°的转向，以确定一个连续的流动路径。
由图1可见，蛇形管40通常为并排设置并分布于端板10和12之间。由图3可见，板状扁平管22嵌套在蛇形管40的两个相临的直管42之间。
最初，蛇形管的外形如图5所示。在板状扁平管22嵌套在直管42之间而在直管42的端部加上管22后，侧面板46加到板状扁平管22的端部，并利用合适的夹具压力，把端板46、板状扁平管22和蛇形管40的直管42压成一个如图3中50所示的堆叠管组，最后再焊在一起。堆叠管组通常为长方形，由于压缩的结果，在伸出堆叠管组的圆拱形管44部分中呈现为图3中所示的球根状。
参照图6，可以看到板状扁平管22包括多个在相对的侧面54，56之间延伸的内部腹板52，以确定通过每个板状扁平管22的多个不连续流动路径58。流动路径58通常与直管42互相垂直。当然，在蛇形管40内也分布有相似的腹板，除了提供在使用热交换器时的压力阻抗外，还用以防止在压缩过程中的收缩。
在实施中，一液体冷却剂可以流入输入口18进入容器14。液体冷却剂从容器14将进入板状扁平管22的端部，以经液体流动路径58进入容器16，然后在输出口20流出。正如前面所提到的，由于各部件被压缩成一个堆叠管组50中并焊在一起，板状扁平管22和蛇形管40的直管42之间形成了良好的热交换。一制冷剂可以经例如集流管30一端的夹具60流入蛇形管40。从此制冷剂将流过每一个蛇形管40。当制冷剂流经蛇形管40的直管42时，将与板状扁平管22中的液体进行热交换。最终，制冷剂流入集流管30，然后被传导到夹具62中，再从这里回到本系统的剩余部件中。
如图所示，装置60作为本系统制冷剂的输入口，由于其尺寸相对较小，一液态制冷剂从这里被导入。从夹具62可以补充气态制冷剂。在这种情况下，热交换器可以用作蒸发器，使流经板状扁平管22的冷却液得以冷却。或者，当用作一冷凝器时气态制冷剂流入较大的夹具62，由较小的装置60流出。气态制冷剂被流经板状扁平管22的冷却液在蛇形管40中冷却、凝结。在这种情况下，热交换器用作一冷凝器。
由前述可知，根据本发明制造的一热交换器非常小巧，并提供了组成各个流动路径的管子之间的紧密接触，从而提供了极好的热交换效果。因而，得到了很高的性能体积比。
