具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
如图1和图2所示，本申请的实施例一提供了一种分液器，分液器包括：筒体10、分配结构20和过滤网30。筒体10具有流入端11、流出端12以及与流入端11和流出端12均连通的连通腔13。分配结构20安装在连通腔13内。本实施例中的分配结构20包括进流板21与分流板22，进流板21与分流板22的形状分别与筒体10的内壁形状相适配，进流板21上设置有进流口211，分流板22与进流板21间隔设置，分流板22设置在进流板21远离过滤网30的一侧，分流板22设置在流出端12处，分流板22上设置有分液出口221，进流板21和分流板22之间具有分液腔23，进流口211和分液出口221均与分液腔23连通。
采用这样的设置，通过在分液器中设置连通腔13，在连通腔13内设置分配结构20，在分配结构20中沿间隔布置进流板21和分流板22以形成分液腔23，并在进流板21上设置进流口211，分流板22上设置分液出口221，流体进入连通腔13后将经进流口211进入分液腔23内进行充分混合后从分液出口221分液流出，增强流体分配与混合的效果。因此，采用本实施例提供的分液器，能够解决现有技术中流体混合不充分、分配效果差的问题。
具体地，在本实施例中，可以通过进流板21、分流板22及筒体10的内壁围成分液腔23，以保证流体进入分液腔23内可以得到充分混合，并在混合后分液出口221处分液流出。
或者，作为其他实施例，可以在进流板21和分流板22之间设置有连接板24，连接板24为环形板状结构，进流板21和分流板22分别安装在连接板24的两端。连接板24的外壁形状与筒体10的内壁形状相适配，以使连接板24安装在筒体10内。采用这样的结构设置，能够便于使得分配结构20为单独的结构，便于进行拆装和调整，保证了分配结构20的分液腔23的密封效果，便于通过分液腔23进行混合，并在混合后经分液出口221有效进行分液。具体地，进流板21与分流板22可以构成用于流体混合的分液腔23，分液腔23优选为具有翻边孔的圆形腔。分液腔23设置在过滤网30之后，流出端12之前，这样可以确保对干净的流体进行分流，避免因杂质冲击而损坏散热器。此外，根据不同的需求与空调器设置，连通腔13还可以为矩形腔或其他具有对称中心的腔体。这里需要指出的是：连接板24与进流板21、分流板22可以为分体结构，或者连接板24与进流板21为一体成型结构，或者连接板24与分流板22为一体成型结构。
在本实施例中，进流口211为圆孔，进流板21为圆板，进流口211的圆心与进流板21的圆心重合(这里的“圆心重合”可以允许进流口211的圆心与进流板21的圆心在一定的误差范围内)。分液出口221为多个，多个分液出口221在空间上环绕进流口211的对称轴设置，多个分液出口221沿圆周方向等间隔设置。
具体地，分液出口221为多个，定义多个为两个或两个以上，进流口211设置在进流板21的中心，并可以与进流板21同心圆设置(这里的同心圆设置包括在公差允许范围内的同心圆设置，“同心圆设置”可以理解为进流口211的圆心与进流板21的圆心重合)，多个分液出口221在空间上环绕进流口211的对称轴设置，多个分液出口221沿圆周方向等间距设置。采 用这样的设置，可以保证经进流口211的流体可以均匀通过分液出口221流向流出端12，实现流体的匀均分液，加强流体的流动性能，从而可以加强空调系统的工作效率。
在本实施例中，进流口211为第一翻边口，第一翻边口的翻边沿进流口211至分液出口221的方向延伸，第一翻边口的翻边设置在进流板21靠近分流板22的一侧，或者说翻边位于分液腔23内。采用这样的设置，可以通过第一翻边口的翻边为流体提供了一个导向通道，能够便于对流体进行导流，以将流体导向至预设位置处。
具体地，当分液出口221为多个时，多个分液出口221以进流口211的对称中心对称布置，这样，第一翻边口的翻边将流体导向至分流板22的位于多个分液出口221之间的板面处并进行碰撞，流体经碰撞后再次反弹回到分液腔23内，并能够再次与进流板21的板面撞击回弹，这样流体经过多次碰撞和回弹，从而便于更好地提高分液腔23的混合均匀性，以便于更好地实现流体的均匀分液。此外，第一翻边口的翻边也相当于提供了一个加速通道，增加了进入分液腔23的流体的流速，以便于更好地提高流体的撞击和回弹，提高混合均匀性。
具体地，分液出口221为第二翻边口，第二翻边口的翻边沿进流口211至分液出口221的方向延伸，第二翻边口的翻边设置在分流板22远离进流板21的一侧。采用这样的结构设置，还能够便于第二翻边口与待连接管件进行连接，方便安装。
具体地，进流口211的第一翻边口结构也可以根据具体需求沿对称中心对称设置为多个。分液出口221的半径小于进流口211的半径，这样的设置可以在分液出口221处增加流体的流速，从而可以提升换热器内的换热效率。
如图2所示，在本实施例中，进流板21和分流板22之间的间距为L1，第一翻边口的翻边长度为L2，进流口211的半径为R1，分液出口221的半径为R2，进流口211与分液出口221之间的径向间距为d。
具体地，上述各数值之间的关系如下：
1/5≤L2/L1≤1/3，这样的设置可以保证流体有充足的空间流出，避免因第一翻边口的翻边与分流板22的距离过近，而使得第一翻边口内流出的流体在与分流板22撞击反弹至第一翻边口内的情况，或者避免因第一翻边口的翻边与分流板22的距离过远，使得流体无法进行多次撞击和回弹，使得流体能够在分液腔23内充分进行混合。
1/4≤R2/R1≤1/2，这样的设置可以使得流体经第一翻边口再进入第二翻边孔使得到进一步加速，更进一步提升系统整体工作效率。
1/2≤d/R1≤2/3，需要说明的是，进流口211与分液出口221之间的径向间距可以指进流口211的对称轴与分液出口221的对称轴之间的间距，分液出口221环绕进流口211设置。通过将进流口211与分液出口221之间的径向间距设置在上述距离比值范围内，能够保证使得经进流口211流出的液体能够撞击至分流板22上并反弹至分液腔23内，从而便于流体在分液腔23内进行充分混合，提高混合均匀性。
在本实施例中，在流入端11处安装有进口管41，在分液出口221处安装有分液管42。
具体地，本实施例中的分液器还包括过滤网30，过滤网30安装在连通腔13内，且沿筒体10的轴向设置在流入端11与分配结构20之间。采用这样的设置，通过在分液器中设置具有流入端11、流出端12以及连通腔13的筒体10，并在连通腔内设置分配结构20及过滤网30，能够使得过滤网30对流入至分配结构20的流体进行过滤，这样，在空调系统中就可以无需再分别单独设置分液器与过滤器，将二者集成于一体，能够尽可能压缩安装空间，减小占用空间。
在本实施例中，过滤网30包括相互连接的安装段31和过滤段32。安装段31的形状与形成连通腔13的筒体10的内壁形状相适配并与筒体10的内壁贴合。同时，过滤段32的过滤截面的直径沿安装段31至过滤段32的延伸方向逐渐减小。采用这样的结构设置，通过安装段31可以便于过滤网30与筒体10配合与安装，同时过滤网30的过滤段32形成漏斗状的结构，可以有效增加过滤面积，增强过滤效果。
在本实施例中，筒体10具有限位凸起14，沿筒体10的轴向，限位凸起14位于安装段31远离流入端11的一侧，限位凸起14与过滤段32抵接限位。限位凸起14的设置有助于筒体10与过滤网30进行抵接，对过滤网30沿从流入端11至流出端12的方向进行限位，这样的设置可以避免过滤网30在工作过程中移动，增强分液器组件的可靠性与稳定性。
在本实施例中，限位凸起14为沿筒体10的径向自筒体10的侧壁向连通腔13内凹陷形成。采用这样的设置，可以无需再单独设置限位结构，仅需在筒体10上加工形成即可，降低了安装难度，节省了制造成本，同时因限位凸起14与筒体10为一体结构，可以避免因单独设置限位结构带来的稳定性降低的隐患。
在本实施例中，筒体10还包括相互连接的扩口段15和分液段16，在扩口段15远离分液段16的一端形成了流入端11，在分液段16远离扩口段15的一端形成了流出端12。过滤网30的安装段31安装在分液段16处。沿筒体10轴向从流入端11至流出端12的方向，扩口段15的截面直径逐渐增大，过滤网30的安装段31位于限位凸起14和扩口段15之间，安装段31能够与扩口段15抵接，对过滤网30从流出端12到流入端11的方向进行限位，即过滤网30可以通过限位凸起14和扩口段15进行轴向限位。这样，作为其他实施方式，还可以设置安装段31与筒体10的内壁之间间隙配合。另外，采用这样的设置，分液段16内的流体压力小于扩口段15内的流体压力，从而降低了过滤网30受到的流体冲击力大小，同时也便于设置充足面积的过滤网30以进行充分过滤，提高过滤效果。
本申请的实施例二中提供了一种换热器组件，包括：换热器和实施例一中提供的分液器，分液器与换热器连接，以此可以在流体进入换热器之前完成分液与过滤，同时因为翻边孔结构的存在，在进入换热器前也可以对流体进行加速，提升换热器的换热效率。
