在本实施例中，沿第一主壳体至第一插接壳体的延伸方向上，第一插接壳体的插接间隙逐渐减小，沿第二主壳体至第二插接壳体的延伸方向上，第二插接壳体的插接间隙逐渐减小。这样，能够更好地避免插接壳体从插接部上脱落的情况。
具体的，本实施例中的第一插接块212具有第一侧面、弧形面和第二侧面，第一侧面、弧形面和第二侧面依次连接设置，第一侧面和第二侧面均用于与第一集流壳体31贴合，弧形面用于与集流壳体围成集流通道。采用这样的设置，能够减小第一插接块212对集流通道内的流体的阻挡作用，以便于集流壳体内流体的顺畅流动。具体的，第二插接块222可以设置成与第一插接块212相同的结构。
具体的，进口部11为第一弧形端口，第一弧形端口用于插入至第一开口部内，以使第一开口部通过第一弧形端口与扁管10内的流体通道连通。或者，出口部12为第二弧形端口，第二弧形端口用于插入至第二开口部内，以使第二开口部通过第二弧形端口与扁管10内的流体通道连通。或者，进口部11为第一弧形端口，第一弧形端口用于插入至第一开口部内，以使第一开口部通过第一弧形端口与扁管10内的流体通道连通；出口部12为第二弧形端口，第二弧形端口用于插入至第二开口部内，以使第二开口部通过第二弧形端口与扁管10内的流体通道连通。采用这样的设置，能够减小插接部队集流通道内流体的阻挡作用，以便于使集流壳体内的流体流动顺畅。
在本实施例中，进口部11为第一弧形端口，第一弧形端口用于插入至第一开口部内，以使第一开口部通过第一弧形端口与扁管10内的流体通道连通；出口部12为第二弧形端口，第二弧形端口用于插入至第二开口部内，以使第二开口部通过第二弧形端口与扁管10内的流体通道连通。采用这样的设置，能够更好地避免第一弧形端口对第一集流通道内的流体的阻挡作用、第二弧形端口对第二集流壳体32内的流体的阻挡作用。
在本实施例中，换热器还包括第二密封垫块40、端盖、连接管70和换热翅片60，端盖设置在集流壳体的相对两端，以通过端盖对集流壳体进行密封。第二密封垫块40设置在端盖和扁管10之间，以通过第二密封垫块40对端盖和扁管10之间的间隙进行密封。第二密封垫块40包括第二主体部、第三插接部和第四插接部，第三插接部和第四插接部均设置在第二主体部上，第三插接部和第四插接部间隔设置，第三插接部突出于第二主体部设置以形成第一定位台阶，第四插接部突出于第二主体设置以形成第二定位台阶，通过第一定位台阶对第一集流壳体31进行定位，通过第二定位台阶对第二集流壳体32进行定位。沿所述第二主体部至第三插接部的延伸方向上，第三插接部的插接宽度逐渐增大，以提高插接稳定性。沿第二主体部至第四插接部的延伸方向上，第四插接部的插接宽度逐渐增大，以提高插接稳定性。
相关技术中的双排折弯微通道换热器的扁管是由两个成型板焊接而成。每个成型板的制冷剂流通区域被凸筋分隔为制冷剂进口部分和出口部分。由于成型板上凸筋的存在，会在扁管与翅片的接触面形成一凹槽。双排折弯微通道换热器作为蒸发器使用时，同样是扁管竖直放置，与常规微通道不同的是，冷凝水既可以沿翅片的百叶窗流下，也可以沿扁管上的竖直凹槽流下。但是由于扁管的厚度受限制，凹槽的尺寸较小，冷凝水由于毛细作用无法沿凹槽流下，同样会导致排水不畅，影响换热性能。
为了解决上述问题，参见图19至图23所示，本申请的实施例提供了一种换热装置，该换热装置包括扁管10及换热翅片60，其中，扁管10由第一成型板和第二成型板组成，扁管10表面具有沿扁管10长度方向延伸的凹槽14，凹槽14为第一成型板和第二成型板朝向扁管10内侧凹陷形成；换热翅片60安装于相邻扁管10之间，换热翅片60对应凹槽的位置处设置有凹口611，凹口611处设置有导流片612，凹口611、导流片612及凹槽14共同形成导流通道90。本申请的换热装置包括扁管10及换热翅片60，翅片的对应凹槽14的位置处设置有凹口611，通过多个凹口、凹槽及导流片形成的导流通道90可以对冷凝水自上至下进行导流，增加了冷凝水流下的路径，从而避免冷凝水滞留的情况发生，与此同时，通过多个凹口处的导流片可以在竖直方向形成侧壁较为光滑的流道，更有利于冷凝水的流动。其中，凹口的形状可以为矩形、梯形或其他形状。
参见图20至图22所示，本实施例中的扁管10自上而下设置有凹槽14，导流切槽的位置与凹槽14的位置相对设置，导流切槽与凹槽14共同形成导流通道90，通过导流切槽与凹槽的配合，形成了导流通道，导流通道具有更大的流通面积，从而更有效地解决了排水不畅的问题。
具体来说，本实施例中的换热翅片60为波纹片，凹口611设于换热翅片60的波峰及波谷位置，以合理利用翅片结构61形成凹口。
其中，导流片612为换热翅片60的一部分，由换热翅片60沿凹口611凹陷形成，且导流片612不贯穿换热翅片60。
为了便于加工，本实施例采用了翻边式加工方法，具体为导流片612为换热翅片60的一部分，由换热翅片60沿凹口611一边翻折形成。加工时，可在翅片的片状结构上加工出两个切缝，之后将两个切缝之间的区域，即导流片向下弯折，从而形成凹口，并使导流片处于凹口的下方。
优选地，多个导流片612均朝同一方向翻折。本实施例中的导流片612的下端抵接在与导流片612相邻的凹口611的内壁上。通过使导流片612的下端抵接在与导流片612相邻的凹口611的内壁上，可以使多个导流片形成的竖直方向的侧壁更加平整，更有利于冷凝水的流动。
本实施例中的导流片612平行于扁管10的长度方向。另一实施例中，本实施例中的导流片612的长度小于换热翅片60的波距，其中，波距为波纹片的波距，即相邻两个波纹顶点之间的距离。
本实施例中的换热翅片60上开设有百叶窗100，其中，凹口611深度小于翅片顶部至百叶窗100的距离。
本实施例中的扁管10具有进口部和出口部，进口部和出口部位于扁管10的同一端，且进口部和出口部均呈弧形结构，以便于引入和引出换热剂。
参见图21所示，为了便于向换热板中供给换热剂，本实施例中的换热装置还包括集流管，集流管设置在扁管10端部，扁管10的内部与集流管连通。
在一种优选地实施例中，为了便于加工，本实施例采用了翻边式加工方法，具体为，本实施例中的导流片612为翅片结构的一部分，向下弯折导流片612以形成凹口611，加工时，可在翅片结构上加工出两个切缝，之后将两个切缝之间的区域，即导流片向下弯折，从而形成凹口，并使导流片处于凹口的下方，本实施例中的导流片612的下端抵接在与导流片612相邻的凹口611的内壁上，一方面，可以使多个导流片形成的竖直方向的侧壁更加平整，另一方面，将导流片设置的较长，可以使的凹口的面积更大，使得流通面积更大。
本实施例中的集流管设置在扁管10的底部，集流管的端部还设置有与外部管路连接的接管。
其中，为了便于加工，本实施例中的换热翅片60由金属板材多次弯折而成，多个翅片结构61为弯折后的金属板材的弯折凸起，在其他实施例中，多个翅片也可为单独设置的多个金属板，翅片结构即为金属板。为了保证导流通道的空间稳定性，本实施例中的多个凹口611中的部分凹口611的侧壁抵接在导向凹槽14的侧壁。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：提高了集流壳体和扁管的连接强度，提高了换热器的耐压性，增大了集流壳体内的流通面积，减小了集流通道内的流动阻力，减小了对制冷系统性能的影响；进口部和出口部位于同一端，便于安装和焊接，减少了密封块的用量，降低了成本；结构更加紧凑结构更加紧凑，翅片侧前后排温度场更加均匀，与两台并排换热器相比，相同迎风面积条件下，提高了换热能力和换热效率，节省机组空间；换热管内部为U型通道，制冷剂在扁管内流过一个“U”字型回路，“U”字型回路的两个流道的宽度可调整，进口部流道和出口部流道的宽度可以相等或不等(优选不等)。作为蒸发器使用时，进口部液体多流道窄，出口部气体多流道宽；作为冷凝器使用时，进口部气体多流道宽，出口部液体多流道窄，通过调整进口部和出口部的流道宽度，优化制冷剂回路中液体侧和气体侧压降，起到减小总压降的作用。增强了集流壳体与插接部的连接稳定性，防止集流壳体从插接部上脱落，防止焊接过程中因集流壳体与插接部的配合间隙过大而出现毛细作用失效的情况，改善并提高了焊接质量。本申请的换热翅片的对应凹槽的位置处设置有凹口，通过多个凹口、凹槽及导流片形成的导流通道可以对冷凝水自上至下进行导流，增加了冷凝水流下的路径，从而避免冷凝水滞留的情况发生，与此同时，通过多个凹口处的导流片可以在竖直方向形成侧壁较为光滑的流道，更有利于冷凝水的流动。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
