具体实施方式
下面将参照附图更详细地描述本公开的示例性实施方式。虽然附图中显示了本公开的示例性实施方式，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施方式所限制。相反，提供这些实施方式是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
应理解的是，文中使用的术语仅出于描述特定示例实施方式 的目的，而无意于进行限制。除非上下文另外明确地指出，否则如文中使用的单数形式“一”、“一个”以及“所述”也可以表示包括复数形式。术语“包括”、“包含”、“含有”以及“具有”是包含性的，并且因此指明所陈述的特征、步骤、操作、元件和/或部件的存在，但并不排除存在或者添加一个或多个其它特征、步骤、操作、元件、部件、和/或它们的组合。文中描述的方法步骤、过程、以及操作不解释为必须要求它们以所描述或说明的特定顺序执行，除非明确指出执行顺序。还应当理解，可以使用另外或者替代的步骤。
尽管可以在文中使用术语第一、第二、第三等来描述多个元件、部件、区域、层和/或部段，但是，这些元件、部件、区域、层和/或部段不应被这些术语所限制。这些术语可以仅用来将一个元件、部件、区域、层或部段与另一区域、层或部段区分开。除非上下文明确地指出，否则诸如“第一”、“第二”之类的术语以及其它数字术语在文中使用时并不暗示顺序或者次序。因此，以下讨论的第一元件、部件、区域、层或部段在不脱离示例实施方式的教导的情况下可以被称作第二元件、部件、区域、层或部段。

如图1至图8所示，根据本公开的实施方式的第一方面，提出了一种管路集成模块100，如图6、图7和图8所示，其中，图6为管路集成模块100焊接后的截面结构示意图，图7为图6中A处的局部放大图，图8为图6中B处的局部放大图。管路集成模块100包括第一板状部件10以及第二板状部件20，其中第一板状部件10沿着其厚度方向设置有第一凹槽11，第一凹槽11在槽口的端部具有第一冲压倒角13。这是由于第一凹槽11是采用冲压工艺制成的，因此，在第一凹槽11的槽口的端部无可避免地会出现冲压倒角，这里将第一凹槽11在槽口的端部的冲压倒角称为第一冲压倒角13。
与此类似，第二板状部件20在其厚度方向上设置有第二凹槽21，第二凹槽21在槽口的端部具有第二冲压倒角23，这是由于第二凹槽21是采用冲压工艺制成的，因此，在第二凹槽21的槽口的端部无可避免地会出现冲压倒角，这里将第二凹槽21在槽口的端部的冲压倒角称为第二冲压倒角23。
第一板状部件10和第二板状部件20盖合设置，且第二凹槽21与第一凹槽11对应设置并合围形成腔体40，腔体40在第一冲压倒角13和第二冲压倒角23之间具有间隙50。
在现有技术中，管路集成模块100也是通过两个板体盖合连接，限定出腔体40，腔体40内具有间隙50，间隙50的存在降低了腔体40的耐高压性能。
其中，这里的盖合连接通常是采用焊接的方式实现两个板体的连接，具体是采用钎料片放置在两个板体之间，通过钎焊实现连接，两片冲压形成的板体在拼接后会在第一冲压倒角13和第二冲压倒角23之间的位置形成间隙50，导致形成的腔体40出现形状突变，而使用炉中钎焊工艺时无法将该间隙50完全填充，当腔体40承受较大静载荷或者交变载荷时，形成的钎缝往往会在间隙 50处在钎缝厚度方向撕裂，对间隙50的填充程度越大，腔体40承受静载荷及交变载荷的性能越好。
另外，由于现有技术中的两块板体是采用冲压工艺制成，容易导致板体出现平面度不佳的情况，如果两个板体在相同位置同时出现起皱、鼓包、平面度差等缺陷，当两个板体盖合后，会出现间隙50叠加的情况，不利于钎缝成型，导致钎缝的强度较低。
在本公开中，管路集成模块100还包括夹板层30，夹板层30设置于第一板状部件10和第二板状部件20之间，并且夹板层30连接于第一板状部件10和第二板状部件20，夹板层30靠近腔体40的端部位于间隙50内，也就是说，夹板层30的部分位于间隙50中。
需要说明的是，这里提到的夹板层30靠近腔体40的端部是指夹板层30的内端部，这是与夹板层30的外端部相对的概念。夹板层30的外端部是背离腔体40的一端，夹板层30的内端部是位于腔体40内的。
本公开中的管路集成模块100对现有技术中的管路集成模块100进行了改进，在第一板状部件10和第二板状部件20之间增加了夹板层30，其中，部分夹板层30位于间隙50内，可以形成对间隙50的填充，另外，在夹板层30和第一板状部件10之间进行的连接，以及在夹板层30和第二板状部件20之间进行的连接，也可以形成对间隙50的填充，从而可以提高对第一冲压倒角13和第二冲压倒角23之间的间隙50的填充，对间隙50的填充量相比较于现有技术中的方案，提高了至少一倍以上，且可以明显提高钎缝的厚度，有效减小腔体40受到载荷后的应力集中水平，提升由两个冲压钣金制成的两块板体进行拼接后形成的腔体40的耐压及耐疲劳性能。
此外，由于本公开中的夹板层30可以采用机加工或者采用别的方式加工，平整度均匀，且表面粗糙度低，将夹板层30放置在 第一板状部件10和第二板状部件20之间，可以使得第一板状部件10和夹板层30之间的间距变小，且可以使得第二板状部件20和夹板层30之间的间距变小，在进行焊接后，避免第一板状部件10的形变和第二板状部件20的形变导致的间隙50叠加，更有利于钎缝的铺展和成型。
在一些可选的实施例中，如图1至图2所示，以及图4和图5所示，其中，图1示意性地示出了根据本公开实施方式的管路集成模块100的立体结构示意图，图2为图1中所示的管路集成模块100处于第二视角的立体结构示意图，图4为图1中所示的第一板状部件10的结构示意图，图5为图1中所示的第二板状部件20的结构示意图。第一板状部件10除了包括第一凹槽11外，还包括第一本体部12，第一本体部12呈平板状，且第一本体部12与第一凹槽11连接，第一本体部12设有第一通孔121，第二板状部件20除了包括第二凹槽21外，第二板状部件20还包括第二本体部22，第二本体部22呈平板状，第二本体部22与第二凹槽21连接，第二本体部22设有第二通孔221。
通过第一本体部12和第二本体部22对应并连接，可以使得第一凹槽11和第二凹槽21合围形成腔体40，腔体40成为液体流动的管体。
需要特别指出的是，这里的第一通孔121和第二通孔221是对应设置的，且数量均为多个，可以通过第一通孔121和/或者第二通孔221对钎缝进行补焊，方便后续对管路集成模块100进行维修和保养，例如，当出现流体泄漏时，根据流体泄漏的位置，通过泄漏位置附近的第一通孔121和/或者第二通孔221进行补焊。
在一些可选的实施例中，夹板层30在间隙50内的伸出长度L为第一冲压倒角13的第一凸弧131半径R的0.2至1.2倍，也就是说L为R的0.2至1.2倍，如0.4、0.6、0.7或者0.8倍等。 其中，这里的伸出长度为图8中标注L对应的长度范围，就是指的在图8中夹板层30在间隙50中露出的长度，如果夹板层30在间隙50内的伸出长度L太小，会导致焊接后的钎缝覆盖夹板层30在间隙50中的端部，导致对间隙50的填充效果太差；但是，如果夹板层30在间隙50内的伸出长度L太长，会导致由于伸出长度L太大会影响腔体40的应用功能，比如降低油分离的效果。
需要说明的是，夹板层30在间隙50中的伸出长度L在不同的位置是相同的，从而对间隙50的填充效果也是均匀和一致的，不会出现局部填充程度高，局部填充程度低的情况。
需要说明的是，这里的第一凸弧131是指的第一冲压倒角13朝向腔体40内部的表面，第二凸弧231是指的第二冲压倒角23朝向腔体40内部的表面，第一凸弧131和第二凸弧231是对称且对应设置的方式，如果第一冲压倒角13和第二冲压倒角23之间不存在间隙50，则第一凹槽11和第二凹槽21合围形成的腔体40的横截面是呈规则的圆形，然而由于间隙50的存在，会使得第一凹槽11和第二凹槽21合围形成的腔体40的横截面是呈不规则的圆形，因此，需要对非圆部分对应的间隙50进行填充，使得腔体40的横截面更加接近圆形，从而提高腔体40的耐压及耐疲劳性能。
在一些可选的实施例中，夹板层30的厚度为0.2毫米至1毫米，厚度过小会导致夹板层30的加工及装配过程比较困难，但是，夹板层30的厚度过大会使腔体40的截面积明显变大，提升腔体40的应力水平，不利于提高腔体40的承压性能及抗疲劳性能。因此，这里的夹板层30的厚度可以是0.3毫米、0.4毫米或者0.5毫米中的一个，当然也可以选择这个范围0.2毫米至1毫米内的其他参数。
在一些可选的实施例中，如图3所示，图3示意性地示出了根据本公开实施方式的管路集成模块100的夹板层30的结构示意图，夹板层30整体呈板状结构，且设有避让口31，避让口31与 腔体40对应设置，从而可以使得夹板层30不会对腔体40内部流体的流动产生影响。夹板层30的内端部是指避让口31的边缘部分。在图3中，夹板层30的外端部围成矩形的形状，夹板层30的内端部形成的形状与腔体40的形状一致。
在一些可选的实施例中，夹板层30通过钎料层分别与所述第一板状部件10和所述第二板状部件20连接，具体地，夹板层30通过钎料层与第一本体部12连接，并且夹板层30通过钎料层与第二本体部22连接，可以形成对间隙50的填充。
这里的钎料层可以设置在第一板状部件10朝向夹板层30的表面，也可以设置在第二板状部件20朝向夹板层30的表面，当然，也可以设置在夹板层30面向第一板状部件10的表面和/或者面向第二板状部件20的表面，具有多种可选的情况，这里不再进行一一举例。
作为经常选择的一种方式，夹板层30朝向第一板状部件10的表面设置有第一钎料层(未图示)，夹板层30朝向第一板状部件10的表面为上表面，并且夹板层30朝向第二板状部件20的表面设置有第二钎料层(未图示)，夹板层30朝向第二板状部件20的表面为下表面，通过在夹板层30的上表面和下表面分别设置第一钎料层和第二钎料层，可以通过第一钎料层实现与第一板状部件10的连接，从夹板层30的上侧通过第一钎料层形成的钎缝实现对间隙50的填充，也可以通过第二钎料层实现与第二板状部件20的连接，从夹板层30的下侧通过第二钎料层形成的钎缝实现对间隙50的填充。
下面将对第一钎料层和第二钎料层的具体设置方式将在下面进行展开阐述。
可选地，第一钎料层可以是固体的，也可以是膏状的，例如第一钎料层为箔状钎料或者膏状钎料，同样地，第二钎料层也可以为箔状钎料或者膏状钎料，当第一钎料层和/或第二钎料层选择 箔状钎料时，可通过电阻点焊的方式将第一钎料层和/或第二钎料层固定在夹板层30的表面上。如果第一钎料层和第二钎料层均选择为膏状钎料的形状，则可以通过涂覆的方式将膏状钎料设置在夹板层30的两个表面上，这里的表面是夹板层30朝向第一板状部件10和朝向第二板状部件20的表面。
在一些可选的实施例中，箔状钎料的厚度为0.03毫米至0.15毫米，具体可以是0.04毫米、0.05或者0.08毫米等，可以预先设置在夹板层30的上表面和/或者下表面。这里需要指出的是，夹板层30的上表面和下表面可以同时设置箔状钎料，也可以同时设置膏状钎料，或者夹板层30的上表面设置箔状钎料，下表面设置膏状钎料，也可以采用相反的设置方式，夹板层30的下表面设置箔状钎料，上表面设置膏状钎料，可以根据方便程度选择使用。
继续参照图7，第一钎焊层在完成焊接后，形成了第一钎缝60，第二钎焊层在完成焊接后，形成了第二钎缝70，其中，第一钎焊层在毛细作用下，形成的第一钎缝60可以对间隙50进行填充，第二钎焊层在毛细作用下，形成的第二钎缝70也可以对间隙50进行填充，再加上夹板层30对间隙50的填充，这三者，即第一钎缝60、第二钎缝70和夹板层30共同形成对间隙50的填充，明显提高了对间隙50的填充效果，填充量相比于现有技术中的技术方案提高了一倍以上。
另外，这里补充说明下第一通孔121和第二通孔221的设置位置以及产生的技术效果，从图5中可以看出，第二通孔221是沿着腔体40的边缘向外等距离延伸一定间隔后设置的，这里的向外，是指向与远离腔体40的方向，且多个第二通孔221是均匀间隔设置的结构，在需要进行补焊的时候，可以通过泄漏位置附近的第二通孔221向第二钎缝70所在的位置填充焊料，对泄漏的位置进行补焊。
与此类似，第一通孔121也是沿着腔体40的边缘向外等距离 延伸一定间隔后设置的，这里的向外，是指向与远离腔体40的方向，且多个第一通孔121是均匀间隔设置的结构，并与第二通孔221相对应设置，在需要进行补焊的时候，可以通过泄漏位置附近的第一通孔121向第一钎缝70所在的位置填充焊料，对泄漏的位置进行补焊。
在一些可选的实施例中，第一凹槽11的数量为至少两个，且至少两个第一凹槽11为间隔设置；夹板层30的数量为至少两个，且至少两个夹板层30间隔设置，夹板层30与第一凹槽11一一对应设置，形成了至少两个腔体40，这也是本公开的一个重要创新之处，下面将对该实施例进行详细描述。
在前面的实施例中，第一凹槽11和第二凹槽21的数量都是一个，第一凹槽11和第二凹槽21合围形成的腔体40为一个，而在该实施例中，第一凹槽11的数量为至少两个，第二凹槽21的数量与第一凹槽11的数量一致，也就是说，管路集成模块100上至少集成了两个腔体40，对于两个腔体40的情况，这里将夹板层30设置为两个独立的情况，而非设置为一体的夹板层30，一方面是由于单独的一个夹板层30有利于钎缝成型，另一方面是方便对至少两个腔体40进行一次性检漏，不需要逐个腔体40分别进行检查，提高了检测的效率。
相应地，为了避免两个腔体40之间出现连通的情况，相邻两个夹板层30之间的间距大于2毫米，如果距离过小，例如相邻两个夹板层30之间的间距为1毫米，将会导致钎焊过程中相邻两个夹板层30之间的钎缝连接，如果相邻的两个腔体40出现内部串漏，无法通过一次检漏检查到出现泄露情况的腔体40。
相邻两个夹板层30之间的间距需要小于一定的尺寸，可根据两个腔体40之间的间距来定，这里的间距，可以通过两个第一凹槽11之间的最近距离来确定。例如，当两个腔体40之间的间距为10毫米时，两个夹板层30之间的间距需要小于10毫米，可以 在2毫米和10毫米之间选出合适的间距，例如4毫米或者5毫米等。
上面提到了腔体40为两个的情况，对于更多个腔体40，例如三个或者四个的腔体40，相应地，夹板层30也设置为三个或者四个，每个夹板层30对应一个腔体40设置，从而实现对每个腔体40的间隙50均进行分别填充。
在一些可选的实施例中，参照图2所示，当腔体40用于油分离场景的情况时，第一凹槽11上设置有进气口14，进气口14连接有进气管，通过进气口14将气体输送到腔体40的内部。另外，在第一凹槽11的一端还形成有第一凸包15，通过第一凸包15对流体的流向进行改变，在第一凹槽11的另一端还形成有回油口16，通过回油口16连接的回油管，实现对油分离后的废油进行转运。相应地，如图5所示，在第二凹槽21上设置有第二凸包25，第二凸包25和第一凸包15对应设置，第二凸包25上设置有出气孔251，通过出气孔251与出气管进行连接。这里的第一凸包15和第二凸包25均呈圆形结构，也可以设置为方形结构或者其他形状的结构。
在一些可选的实施例中，第二凹槽21与进气口14对应的位置还设置有导流部24，导流部24采用冲压工艺制成，可以对从进气口14进入的气体进行导流，使得气体能够顺畅地进入腔体40的内部。相应地，为了避免夹板层30对气体产生影响，在夹板层30上还设置了冲压口311，冲压口311形成了避让口31的一部分。
另外，这里的第一板状部件10和第二板状部件20均采用不锈钢材质制成，采用不锈钢材质相比较于铜合金而言，成本较低，且冲压性能较好，可以降低空调室外机的成本。另外，对于夹板层30而言，选择的材质也为不锈钢，并与第一板状部件10和第二板状部件20的材质相同，如可以采用308不锈钢或者2209不锈钢等。
需要说明的是，这里的第一板状部件10和第二板状部件20、 以及夹板层30三者的外形尺寸是一样的，整体的外轮廓均为矩形。当然，钎料层的形状和尺寸是与夹板层30的形状和尺寸是一致的。
本公开实施例的第二方面，提供了一种空调室外机，空调室外机包括上面实施例中所提到的管路集成模块100。这里的空调室外机包括连接管和上面实施例中所提到的管路集成模块100，连接管与管路集成模块100连接。其中，连接管在连接孔的位置与管路集成模块100连接。
这里的连接管包括进气管、排气管和出油管等，这里的连接孔包括进气口14、回油口16和出气孔251等，可以根据腔体40内设置的功能件设置相应的接口，并与相应的连接管进行连接，例如功能件为过滤组件时，设置与过滤器功能的相关连接管路，对于其他的情况，这里不再进行举例说明。
空调室外机除了这些结构外，还包括压缩机、低压罐、电子膨胀阀以及室外换热器等，这些都是现有技术中的常见部件，这里不再进行展开阐述。
本公开的第三方面还公开了一种管路集成模块100的制备方法，管路集成模块100为上面实施例中所提到的管路集成模块100，制备方法包括：
通过冲压方式获得具有第一凹槽11的第一板状部件10，并加工出具有第二凹槽21的第二板状部件20；
具体地，可以通过在平板上冲压的方式形成第一凹槽11，并通过在另一个平板上冲压的方式形成第二凹槽21，其中，这里的第一凹槽11和第二凹槽21的截面均呈半圆形，从而可以使得第一凹槽11和第二凹槽21围成近似于圆形的截面。
加工出具有避让口31的夹板层30，避让口31与第一凹槽11和第二凹槽21合围形成的腔体40形状一致。
在这里，夹板层30可以采用矩形板，通过线切割的方式加工出避让口31，为下一步做好准备。
将夹板层30设置于第一板状部件10和第二板状部件20之间，并和第一板状部件10以及第二板状部件20连接。
在将夹板层30放置于第一板状部件10和第二板状部件20之间前，需要在夹板层30的上表面形成第一钎料层，在夹板层30的下表面形成第二钎料层，这里的第一钎料层和/或者第二钎料层可以是膏状，也可以是箔状，当第一钎料层和/或者第二钎料层均为箔状钎料时，采用电阻点焊的方式固定在夹板层30的上表面和下表面。
其中，这里的连接主要是焊接，通过钎焊的方式将第一板状部件10以及第二板状部件20均与夹板层30实现连接。
在一些可选的实施例中，夹板层30与第一板状部件10通过钎焊连接，并且/或者，夹板层30与第二板状部件20也是通过钎焊连接。
钎焊是采用炉中钎焊的方式来实现的，可以一次焊接多个管路集成模块100，实现小批量生产，钎焊的过程可以采用真空钎焊的方式，避免被空气影响钎焊的强度。
需要注意的是，在安装过程中需要保证夹板层30在间隙中的伸出长度L满足规定的要求，即夹板层30在间隙50内的伸出长度L为第一冲压倒角13的第一凸弧131半径R的0.2至1.2倍，例如这里的伸出长度L可以为2毫米。
在常见的尺寸中，第一板状部件10和第二板状部件20的厚度相同，均为1.2毫米，箔状钎料的厚度为0.05毫米，伸出长度L为2毫米，在试验完成后，在安装过程中的固定方式均采用电阻点焊的方式，装配完成后的样品放入真空钎焊炉中，可以形成对间隙50的近似完全填充的效果，提高了腔体40的承压性能和耐疲劳性能。
以上所述，仅为本公开的一些具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开 揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
