请参见图1及图2，本申请提供的一种微通道换热器100，安装于制冷系统中，微通道换热器100中流动有介质，微通道换热器100协助介质与外界进行热交换。
具体地，微通道换热器100包括多片翅片10和多根扁管20，多片翅片10并列且间隔设置以形成多排翅片10，多根扁管20平行设置以形成多层扁管20，翅片10上开设有接插槽11，扁管20穿设于接插槽11内。需要解释的是，本申请的多排翅片10指的是，沿着扁管20的长度方向，翅片10排成多排，多层扁管20指的是沿着微通道换热器100的高度方向，多根扁管20平行设置为多层，下文的多列指的是，沿着微通道换热器100的宽度方向，扁管20和翅片10分别排成前后多列。
微通道换热器100还包括分配器30及转接管40，分配器30上设有多根毛细管31，转接管40的一端与毛细管31连通，另一端与扁管20连通。可以理解，介质在分配器30中均匀分配后进入扁管20中，利用分配器30代替传统的集流管，能够简化工艺，若需要改变流程，只需要选择合适的分配器30及删减毛细管31的数量即可，若利用集流管分配，则需要在在集流管60上开设多个扁管槽，工艺复杂。
转接管40朝向扁管20的管口与扁管20的管口相适配，扁管20的一端伸入转接管40内，加强焊接强度。
请参见图3及图7，转接管40朝向扁管20的管口的宽度W 1大于扁管20的管口W 2宽度，且转接管40朝向扁管20的管口的高度H 1大于扁管20的管口的高度H 2。可以理解，由于扁管20及转接管40为铝材制作，不宜扩口，将转接管40的管口尺寸设计得比扁管20的管口大，方便扁管20的一端能够顺利地插入转接管40内。需要说明的是，转接管40朝向扁管20的管口的宽度及高度都指的是转接管40朝向扁管20的管口的内部尺寸，不包括转接管40的厚度，同样，扁管20的管口的尺寸同样也不包括扁管20的厚度。
本申请还提供的一种转接管40，安装于微通道换热器100中，转接管40用于连接相邻扁管20，或者，转接管40用于扁管20和毛细管31的连接。
相关技术中的微通道换热器中，扁管与转接管的连接通常未设置限位结构，如此不仅使得扁管与转接管之间不便于焊接，而且也使得扁管与转接在焊接过程中产生移位的现象，给焊接造成不便。
为解决相关技术中的微通道换热器中所存在的问题，本申请提供了一种安装于微通道换热器100中的转接管40，该转接管40用于连接扁管20。转接管40为多个，部分转接管40的一端连接于毛细管31，另一端连接于扁管20，部分转接管40的两端均连接于扁管20。也就是说，连接于毛细管31的转接管40采用上述一端的管口为圆形，另一端的管口为长条孔状的结构，两端均连接于扁管20的转接管40采用弯管结构。
转接管40具有与扁管20相适配的第一管口401，第一管口401供扁管20插入，转接管40的内壁设有限位部402，限位部402抵接于扁管20的一端及/或抵接于扁管20的侧壁，用于对扁管20限位。
需要说明的是，当需要连接相邻扁管20，或者，当需要连接扁管20和毛细管31时，需先把每根扁管20一一对应的插入每根转接管40中，然后一体进行焊接，因此，为了避免在焊接过程中扁管20和转接管40之间发生移位，本申请在转接管40内壁上设置用于对所述扁管20进行限位的限位部402。
为了保证扁管20和转接管40之间在焊接前的连接固定性，沿扁管20轴线方向，限位部402需对扁管20插入转接管40内的深度进行限位；沿垂直于扁管20轴线方向，限位部402还需对扁管20在转接管40内晃动进行限位。
如图10及图11所示，在本申请一实施例中，限位部402包括第一凸部402A，第一凸部402A设置于转接管40的内壁上，且朝向远离转接管40内壁的方向延伸，第一凸部402A用于抵接扁管20的一端，使得伸入转接管40内的扁管20的端面能够抵接于第一凸部402A上，以此对扁管20在转接管 40内的插入深度进行限位，同时，第一凸部402A的设置对制冷剂产生扰流作用，使得制冷剂的均匀性得到提高，提高换热器的换热效率。
具体地，请参见图11及图12，第一凸部402A的相对转接管40内壁的凸出高度不能太大，也不能太小，需要设置在一个合适的范围内。定义第一凸部402A相对于转接管40的内壁凸出的高度为H 3，扁管20的高度为H 1，转接管40内具有相对设置的第一内壁403及第二内壁404，第一凸部402A设于第一内壁403及/或第二内壁404上，第一内壁403与第二内壁404之间的距离为H 2，扁管20的高度为H 1；其中，第一凸部402A相对于转接管40的内壁凸出的高度H 3、扁管20的高度H 1、第一内壁403与第二内壁404之间的距离H 2满足关系式0.2mm≤[H 3-(H 2-H 1)]≤3mm。即，[H 3-(H 2-H 1)]的值可以为0.2mm、1mm、2mm、3mm或者落入该范围值内的任一数值。扁管20的高度H 1为扁管20的外部高度，不是扁管20内部通道的高度。
需要说明的是，如若第一凸部402A相对于转接管40的内壁凸出的高度H 3过大，会导致第一凸部402A在转接管40内一定程度上阻碍了介质流动，甚至造成节流；如若第一凸部402A相对于转接管40的内壁凸出的高度H 3过小，则可能无法实现限位功能；因此，使得第一凸部402A相对于转接管40的内壁凸出的高度H 3处于一个合适的范围内，使其既能够保证对扁管20端面的限位，又能够避免H 3过高造成介质流动阻力过大。
沿转接管40内壁的周向方向，第一凸部402A的数量可以设置为一个、两个、三个或多个，在此对第一凸部402A的数量不作限定。
可选地，在本实施例中，第一凸部402A的形状可以为半圆形、方形或梯形，在此不作限定。
另外，在该实施例中，第一凸部402A设置于转接管40内壁上的位置其实质就相当于扁管20插入转接管40内的最大位置，对于扁管20插入转接管40内的深度，也需要存在一个合适的范围内。定义第一凸部402A与第一管口401的端面之间的间距即扁管20插入转接管40内的深度为L 1，L 1满足关系式2mm≤L 1≤10mm。即，第一凸部402A与第一管口401的端面之间的间距L 1可以为2mm、4mm、6mm、8mm、10mm或者落入该范围值内的任一数值，在此不作限定。
需要说明的是，如若扁管20插入转接管40内的深度L 1过大，则会一定程度上阻碍内部介质的流动；如若扁管20插入转接管40内的深度L 1过小，则会减少扁管20与转接管40之间的接触面积，从而降低两者之间的焊接强度。因此，通过使得第一凸部402A与第一管口401的端面之间的间距L 1满足关系式2mm≤L 1≤10mm，从而使得扁管20插入转接管40内的深度处于一个合适的范围值，如此既能够避免扁管20插入过深引起阻流，又能够避免扁管20插入过浅而降低焊接强度。
如图10及图13所示，在一实施例中，限位部402包括第二凸部402B，第二凸部402B设置于转接管40的内壁上，且朝向远离转接管40内壁的方向延伸，第二凸部402B相对于第一凸部402A远离第一管口401设置，第二凸部402B凸出于转接管40的内壁的高度小于第一凸部402A凸出于转接管40的内壁的高度，第二凸部402B用于抵接于扁管20的外侧壁，主要是为了避免扁管20相对于转接管40的内壁之间产生晃动。
可以理解的是，本申请通过使得限位部402包括第一凸部402A及第二凸部402B，第一凸部402A用于抵接扁管20的一端，第二凸部402B用于抵接于扁管20的外侧壁，从而对扁管20插入转接管的深度，以及扁管20在转接管40内产生晃动均进行限位，进一步保证了扁管20和转接管40之间的连接固定性，方便焊接。
具体地，请参见图13及图14，为了保证第二凸部402B对扁管20的限位效果，则需要使得第二凸部402B与扁管20外侧壁之间过盈配合；定义第二凸部402B相对于转接管40的内壁凸出的高度为H 4，第二凸部402B设于第一内壁403及/或第二内壁404上，扁管20的高度H 1、第二凸部402B相对于转接管40的内壁凸出的高度H 4、第一内壁403与第二内壁404之间的距离H 2满足关系式0mm≤[H 4-(H 2-H 1)]≤0.2mm。即，[H 4-(H 2-H 1)]可以为0mm、0.1mm、0.2mm或者落入该范围值内的任一数值。
需要说明的是，通过使得扁管20的高度H 1、第二凸部402B相对于转接管40的内壁凸出的高度H 4、第一内壁403与第二内壁404之间的距离H 2满足关系式0mm≤[H 4-(H 2-H 1)]≤0.2mm，从而保证第二凸部402B和扁管20之间过盈配合，进而使得第二凸部402B将扁管20固定于转接管40内，解决了扁 管20在与转接管40焊接过程中产生移位的问题。
沿转接管40内壁的周向或轴向，第二凸部402B的数量可以设置为一个、两个、三个或多个，在此对第二凸部402B的数量不作限定。
可选地，在本实施例中，第二凸部402B的形状可以为半圆形、方形或梯形，在此不作限定。
值得注意的是，在本实施例中，可以仅在转接管40内壁设置第一凸部402A或第二凸部402B，当然，也可以同时设置第一凸部402A以及第二凸部402B。第一凸部402A及第二凸部402B可通过在转接管40外壁通过施压加工形成。
为了保证扁管20和转接管40之间的焊接强度，转接管40的内壁和扁管20的外壁之间需要留有供焊料融化后渗透的间隙，且该间隙的大小需要位于一个合适的范围值内。扁管20的高度H 1和第一内壁403与第二内壁404之间的距离H 2满足关系式0.02mm≤(H 2-H 1)≤0.4mm，即，(H 2-H 1)的值可以为0.02mm、0.1mm、0.2mm、0.3mm、0.4mm或者落入该范围值内的任一数值。
需要说明的是，转接管40的内壁和扁管20的外壁之间的间隙不能过小，过小会导致焊料无法流动；转接管40的内壁和扁管20的外壁之间的间隙也不能过大，过大会导致转接管40和扁管20之间无法焊接。通过使得扁管20的高度H 1和第一内壁403与第二内壁404之间的距离H 2满足关系式0.02mm≤(H 2-H 1)≤0.4mm，从而使得扁管20外壁和转接管40内壁之间间隙配合，如此有利于焊料的流动。
进一步地，在本申请一实施例中，转接管40具有第二管口405，第二管口405位于转接管40远离第一管口401的一端，第二管口405呈圆形，第二管口405用于与毛细管31连接。由于毛细管31特别细，且横截面为圆形，而扁管20的横截面呈条形孔状，因此两者之间无法直接对接连接，需要通过转接管40的转接来实现两者的连通，其中，转接管40靠近毛细管31一端设置为与毛细管31相适配的圆形，转接管40靠近扁管20的一端设置为与扁管20相适配的长条形。
在本申请另一实施例中，在多排微通道换热器100中，转接管40为弯管，转接管40的两端均具有第一管口401，转接管40的两端用于连接相邻排的扁管20。由于相关技术中的微通道换热器中通常将扁管进行折弯来实现多排扁管，扁管折弯会造成扁管损伤，而且，折弯半径较大，会增加微通道换热器的整体体积，并且，在折弯过程中，会导致翅片发生变形影响换热效率，因此本申请采用转接管40来连接相邻扁管20，从而避免翅片10折弯发生变形。当转接管40的两端均连接扁管20时，则在转接管40的两端均设置第一凸部402A和第二凸部402B。
本申请提供的转接管40，通过使得限位部402抵接于扁管20的一端及/或抵接于扁管20的侧壁，用于对扁管20限位，从而保证扁管20和转接管40之间的连接固定性，进而使得扁管20与转接管40在焊接过程中不会产生移位的现象，增强了扁管20和转接管40的焊接性能。
相关技术中的微通道换热器中，通常采取手工焊接的形式对扁管和转接管进行焊接，该方法对于焊接的控制及效果不佳，无法很好的对焊料及焊缝进行控制，且手工焊人工制造的成本较高，不利于大量投入使用。
请参见图16及图17，为解决相关技术中的微通道换热器中所存在的上述问题，本申请提供的微通道换热器100还包括缩口管70及扩口管80，扩口管80连接于转接管40，缩口管70连接于扁管20。缩口管70通过扁管20缩口形成，扩口管80通过转接管40扩口形成。或，缩口管70连接于转接管40，扩口管80连接于扁管20；扩口管80通过扁管20扩口形成，缩口管70通过转接管40缩口形成。缩口管70外套设有焊环90，缩口管70伸入扩口管80内并与扩口管80焊接连接。
需要说明的是，本申请提供的微通道换热器100通过使得缩口管70外套设有焊环90，缩口管70伸入扩口管80内，然后一起进行炉中钎焊，焊环90融化后渗透于缩口管70外壁和扩口管80内壁之间，以此将缩口管70与扩口管80固连；相比于手工焊接来说，采用炉中一体钎焊的方式焊接扁管20和转接管40焊接一致性更高，扁管20和转接管40能够和微通道换热器100的其他部件一起焊接，降低了成本，提高焊接效率，也提高了扁管20和转接管40的焊接一致性。
如图18所示，在本实施例中，扁管20连接于缩口管70，转接管40连接于扩口管80，缩口管70伸入扩口管80内与扩口管80进行焊接。当然，在其他实施例中，也可以是转接管40连接于缩口管70，扁管20连接于扩口管80。
值得注意的是，扁管20连接于缩口管70可以是扁管20和缩口管70分体设置，也可以是直接对扁 管20缩口设置，转接管40连接于扩口管80可以是转接管40和扩口管80分体设置，也可以是直接对转接管40扩口设置；或者，转接管40连接于缩口管70可以是转接管40和缩口管70分体设置，也可以是直接对转接管40缩口设置，扁管20连接于扩口管80可以是扁管20和扩口管80分体设置，也可以是直接对扁管20扩口设置。
进一步地，缩口管70包括相互连接的第一段71及第二段72。第一段71的外径沿着靠近第二段72的方向逐渐减小，焊环90套设于第一段71外，沿着缩口管70的轴向，第一段71的长度为L 1，焊环90的横截面的直径为D 1，第一段71的长度L 1满足关系式：D 1≤L 1≤1.2D 1。即，第一段71的长度L 1可以为D 1、1.1D 1、1.2D 1或者落入该范围值内的任一数值。
为了使第一段71有足够的安装空间给焊环90安装，保证焊环90更好的套设于第一段71外，且使得焊环90不会滑至其他地方影响焊接，那么第一段71沿缩口管70轴线方向的长度L 1至少与焊环90的直径D 1相等，也可以一定程度上大于焊环90的直径D 1，但是第一段71沿缩口管70轴线方向的长度L 1不能过大，过大则会导致材料产生不必要的浪费，因此本申请将第一段71的长度L 1限定在D 1≤L 1≤1.2D 1范围内最为合适。
进一步地，第二段72的长度为L 2，且第二段72的长度L 2满足关系式：3mm≤L 2≤5mm。即，第二段72的长度L 2可以为3mm、4mm、5mm或者落入该范围值内的任一数值，在此不作限定。
需要说明的是，为了保证缩口管70和扩口管80之间的焊接强度，第二段72需要具有一定长度，但是该长度又不能过长，过长会对缩口管70和扩口管80内的介质产生阻流。
焊环90的横截面呈圆形，焊环90整体呈椭圆环形，并套接在第一段71外壁上，使得焊环90的形状与扁管20的相状相适配，使得焊料能够均匀地覆盖缩口管70的外壁的周向，从而保证焊接质量。扁管20的宽度为W 1，第二段72的宽度为W 2，焊环90的内圈长轴为D，焊环90的内圈长轴D满足关系式：W 2≤D≤W 1，其中，W 2＜W 1，使得焊环90能够顺利地套至第一段71外。即，焊环90的内圈长轴D可以为W 2、W 1或W 2～W 1内的任一数值。扁管20的宽度为W 1指的是扁管20外部的宽度，第二段72的宽度为W 2指的是第二段72外部的宽度。需要解释的是，焊环90的内圈为椭圆形，椭圆形具有长轴和短轴，焊环90内圈的长轴为焊环90内圈的宽度，即，焊环90内圈的最大直径。
由于不同的微通道换热器100中的扁管20会根据不同情况设计为不同大小的尺寸，当扁管20的宽度较大时，其外周长较长，因此需要更多的焊料填充，因此需要使得焊环90的横截面的直径D 1能够随着扁管20宽度W 1的增大而呈一定比例的增大，以此来保证扁管20和转接管40之间的焊接强度。在本申请中，将焊环90的横截面的直径D 1满足关系式D 1＝0.06W 1，即，焊环90的横截面的直径D 1可以为0.06倍的扁管20宽度W 1。
进一步地，缩口管70内的宽度为W 3，转接管40内的宽度为W 4，0.8W 4≤W 3≤1.2W 4。即，缩口管70内的宽度W 3可以为0.8W 4、0.9W 4、W 4、1.1W 4或0.8W 4～1.2W 4内的任一数值。缩口管70内的宽度为W 3指的是缩口管70内部通道的宽度，转接管40内的宽度为W 4指的是转接管40内部通道的宽度。
需要说明的是，介质在从扁管20到转接管40之间流动的过程中，如若管径突然增大或者突然减少都会增大介质的流动阻力，从而导致流量损失，为了解决该问题，需要尽量使得介质在流动过程中的管内径保持一致，因此本申请将缩口管70内的宽度W 3限定在0.8W 4～1.2W 4范围内，减少了介质流动阻力。
如图18及图19所示，当焊环90套设于第一段71外壁上时，缩口管70伸入扩口管80内，扩口管80靠近缩口管70一端的端面抵接于焊环90上，为了便于焊环90熔化后渗透于缩口管70外壁和扩口管80内壁之间，需要使得缩口管70的外壁与扩口管80的内壁之间间隙配合，从而使得焊环90熔化后的焊料能够在该间隙内充分流动。
具体地，缩口管70的外壁与扩口管80的内壁间隙为H，H满足关系式：0.1mm≤H≤0.35mm。即，缩口管70的外壁与扩口管80的内壁间隙H可以为0.1mm、0.2mm、0.35mm或者落入该范围内的任一数值，在此不作限定。
需要说明的是，通过使得缩口管70的外壁与扩口管80的内壁间隙H满足关系式0.1mm≤H≤0.35mm，从而使得间隙H处在一个合适的范围内，若间隙H太小，则导致焊料无法流动；若间隙H太大，则降低了扁管20和转接管40之间的焊接强度。
扁管20可多列，相邻列的扁管20通过转接管连接，如此设置，扁管20可不必折弯，减少了扁管20的损伤，也同时避免折弯影响翅片10，折弯半径大大减小，从而减小了产品尺寸。
扁管20的管口为扁平形，毛细管31和扁管20之间需要转接连接。
在一实施例中，转接管40一端的管口呈圆形，并与毛细管31焊接连接，另一端通过缩口管70及扩口管80与扁管20焊接连接。在另一实施例中，转接管40呈U型，两端均通过缩口管70和扩口管80与扁管20焊接连接。
本申请提供的微通道换热器100，通过使得缩口管70外套设有焊环90，缩口管70伸入扩口管80内并与扩口管80焊接连接，如此便能采用炉中钎焊的方式焊接扁管20和转接管40，不仅能够提高焊接效率，也提高了扁管20和转接管40的焊接一致性。
在一些实施例中，扁管20可以为多列，即，扁管20至少包括第一列扁管21和第二列扁管22，微通道换热器100还包括多个弯管50，相邻列的扁管20通过弯管50连通；或，同一列的扁管20之间通过弯管50连通；或，相邻列的扁管20通过弯管50连通，且同一列的扁管20之间通过弯管50连通，以实现介质的不同流程的转向。弯管50与扁管20之间分体设置，并通过焊接固定连接，从而减少扁管20的折弯工艺。可以理解，在折弯的过程中，会发生翅片10变形的问题，本申请无需折弯，能够缓解翅片10因折弯而变形的问题。
如图20至图36所示，在一些实施例中，扁管20为多个，多个扁管20间隔设置。接插槽11为多个，多个接插槽11沿翅片10的延伸方向间隔设置。接插槽11与扁管20的形状相适配，以使翅片10通过接插槽11插接在扁管20上。弯管50包括连接段51和折弯段52，连接段51为两个，两个连接段51分别设置在折弯段52的两端，两个连接段51和折弯段52连接以形成U形管结构，两个连接段51分别与两个扁管20连接；其中，连接段51套设在扁管20上深度为P，2mm≤P≤20mm。
采用本实施例提供的换热器，将多个扁管20沿竖直方向或者与竖直方向呈小角度(此处的小角度可以为小于15°)间隔排布，在安装时将翅片10直接插接在多个扁管20上，并通过弯管50将扁管20进行连接。翅片10可以为多个，将多个翅片10沿扁管20的延伸方向间隔插设在扁管20上。翅片10为竖直的插片式结构。这样，换热器在工作过程中，能够便于通过该翅片10进行排水，提高了排水的通畅性。在本实施例中，通过弯管50将两个扁管20进行连接，增加了回路的设计灵活度。通过将连接段51套设在扁管20上的深度设置在上述范围内，能够便于保证连接段51和扁管20的连接强度，也便于进行焊接，提高整体结构的作用可靠性。
具体地，本实施中的折弯段52可以为U形弯管结构。
具体地，在连接段51和折弯段52之间还设置有过渡段53，沿折弯段52至连接段51的延伸方向，过渡段53的流通面积逐渐减小。折弯段52为圆管结构，折弯段52的外径为D，扁管20宽度为W。5mm≤D＜6mm时，0＜W≤8mm，2mm≤P≤5mm。6mm≤D＜7mm时，0＜W≤10mm，3mm≤P≤10mm。7mm≤D＜8mm时，0＜W≤12mm，3mm≤P≤15mm。8mm≤D＜10mm时，0＜W≤15mm，3mm≤P≤20mm。10mm≤D＜12mm时，0＜W≤18mm，4mm≤P≤20mm。12mm≤D＜15mm时，0＜W≤21mm，4mm≤P≤25mm。15mm≤D＜18mm时，0＜W≤27mm，5mm≤P≤25mm。18mm≤D＜25mm时，0＜W≤38mm，5mm≤P≤25mm。
在本实施例中，连接段51的内壁面由依次连接的顶面、第一侧面、底面和第二侧面围成，顶面和底面均为平面。第一侧面和第二侧面均为弧面，弧面可以与顶面或底面相切或不相切，弧面可以为圆弧面或椭圆弧面。或者，可以将第一侧面和第二侧面均为平面，顶面和底面与第一侧面的连接处均为圆弧过渡，顶面和底面与第二侧面的连接处均为圆弧过渡。或者，可以将第一侧面和第二侧面均为椭圆面。或者，第一侧面和第二侧面均为折弯面，该折弯面可以为两个相连的平面以形成三角头扁管20。或者，连接段51的内壁面的截面为椭圆面。
具体地，弯管50的两个连接段51均为轴对称结构，两个连接段51的对称中心连接以形成连接轴线，弯管50的管口的长度延伸方向与连接轴线之间具有夹角α，0≤α≤90°。采用这样的结构设置，可以使得弯管50的两个连接段51平齐设置或错位设置，以实现具有不同夹角α的弯管50对不同高度和位置的扁管20进行连接。在一些实施例中，20°≤α≤90°。
在本实施例中，接插槽11的宽度为Gw，接插槽11的高度为Gt，1.5≤Gw/Gt≤10。采用这样的结构设置，能够便于提高插接的稳定性，以使翅片10和扁管20的连接稳定。
在一些实施例中，翅片10与扁管20垂直设置，使得在安装时，能够将翅片10竖直设置，利于排水，防止翅片10上结霜而影响换热效果。
翅片10具有第一侧12和第二侧13，第一侧12靠近迎风侧，接插槽11的一端贯穿第二侧13，在安装时，从第一侧12将扁管20装入，能够保护翅片10，由于翅片10较薄，将扁管20从第一侧12装入，能够防止翅片10变形。
接插槽11靠近第二侧13的槽口的内壁与第二侧13的侧面之间倒角或倒圆角设置，以使扁管20能够更顺畅地插入接插槽11内。
翅片10上设有多个第一凸起14，第一凸起14能够加强翅片10的强度，防止翅片10变形。
请参见图4，在一实施例中，第一凸起14为多个，多个第一凸起14依次排列形成呈波纹形。
请参见图5，在另一个实施例中，第一凸起14为圆形。
请参见图6，在又一个实施例中，第一凸起14为月牙形。
请参见图7，在再一个实施例中，第一凸起14为方形。
在一些实施例中，第一凸起14为波纹形，不仅起到加强作用，还起到排水作用。
在其他实施例中，第一凸起14还可为S形、三角形等形状。
可选地，波纹状的第一凸起14从翅片10的一端延伸到另一端，在接插槽11处截断，加强排水作用，能够防止冷凝水不能及时排出而造成结霜，从而影响换热效果。
请参见图7，第一凸起14上开设有条缝15，条缝15贯穿翅片10的两侧面以形成过风通道，使得风能够从当前的翅片10通过条缝15吹至相邻的翅片10，加强紊流，从而加强换热效果。
在一些实施例中，条缝15开设于第一凸起14的两侧，风能够顺势地从第一凸起14侧面的条缝15吹入或吹出。
请参见图8及图9，翅片10竖直安装，翅片10靠近所述第一侧12的侧面具有多个第二凸起16，多个第二凸起16沿翅片10的宽度方向依次分布形成波纹结构，第二凸起16的两端分别朝翅片10长度方向的两侧延伸并贯穿翅片10的两端。本申请的微通道换热器100作为蒸发器使用，第一侧12靠近迎风侧，则靠近第一侧12的翅片10上更容易形成冷凝水，将第二凸起16设置在靠近迎风侧，从而缓解结霜问题，避免翅片10上结霜而影响换热效果。需要解释的是，本申请中第二凸起16的波纹结构指的是，第二凸起16为长条形，沿着翅片10的宽度方向，多个第二凸起16之间形成起伏的波纹形状，相邻的第二凸起16之间形成排水槽。第二凸起16的横截面可为三角形、多边形等。
接插槽11的长度小于翅片10的宽度，从而使得翅片10上能够具有空间设置第二凸起16，第二凸起16不会被扁管20阻隔而影响排水。
在一些实施例中，翅片10与连接段51之间的最小间距(也即为端部靠近连接段51处的翅片10与连接段51之间的间距)为C，0≤C≤80mm。采用这样的结构设置，能够便于有效进行换热，提高换热效果。
在一些实施例中，翅片10包括本体部17及翻边结构18，翻边结构18连接于本体部17，接插槽11、第一凸起14及第二凸起16均设于本体部17上。翻边结构18设置在接插槽11处，翻边结构18相对于本体部17凸出设置，翻边结构18用于与扁管20配合。翻边结构18至少部分与扁管20的侧面抵接，能够加强翅片10与扁管20的焊接面积，加强焊接强度，以便于更好地保证连接稳定性。采用这样的结构设置，能够便于进一步提高插接的稳定性。
翻边结构18包括第一翻边181，第一翻边181设于接插槽11处并环绕接插槽11的周缘设置，第一翻边181朝向扁管20的长度方向延伸，第一翻边181与扁管20的侧面抵接，以使第一翻边181围成与扁管20相适配的形状。第一翻边181能够加强翅片10与扁管20的焊接面积，加强焊接强度。采用这样的结构设置，能够便于增加与扁管20的接触面积，提高对扁管20的插接定位稳定性。
具体地，第一翻边181的高度为H 1，0＜H 1≤1mm。采用这样的结构设置，能够便于更好地提高插接的稳定性。具体地，第一翻边181的高度是指第一翻边181凸出于本体部的高度。
翻边结构18还包括第二翻边182，第二翻边182连接于第一翻边181，第二翻边182朝向扁管20的长度方向延伸。第二翻边182与第一翻边181位于同一平面，第二翻边182可为一个，也可为多个，多个第二翻边182间隔地环绕接插槽11设置，能够进一步加强扁管20和翅片10的焊接强度。多个第 二翻边182可以沿接插槽11的周缘方向间隔设置在第一翻边181上，第二翻边182所在的平面与第一翻边181所在的平面重合。采用这样的结构设置，能够便于进一步提高插接的稳定性。由于多个第二翻边182间隔设置，通过相邻两个第二翻边182之间的间隙也便于将翅片10进行拆卸。
具体地，第二翻边182的高度为H 2，接插槽11的高度为Gt，0.25＜H 2/Gt＜1。采用这样的结构设置，既能够保证插接的稳定性，也能够便于进行拆卸。具体地，第二翻边182的高度是指第二翻边182凸出于第一翻边181的高度。
具体地，本实施例中的第二翻边182的宽度的取值范围为1mm至6mm。
翻边结构18还包括第三翻边183，第三翻边183连接于第二翻边182，第三翻边183与第二翻边182垂直设置，多个第三翻边183与多个第二翻边182一一对应地设置，各个第三翻边183设置在第二翻边182远离第一翻边181的一侧，以避让接插槽11。第三翻边183与相邻的扁管20抵接，起到限位作用。在一些实施例中，第三翻边183可以为多个，第三翻边183与第二翻边182呈预设角度设置，以使第三翻边183避让接插槽11设置。
在一些实施例中，翅片10也为多列，靠近迎风侧一列的翅片10一一对应地抵接于后一列翅片10，形成多排翅片10。每列所述翅片10包括多排间隔设置的所述翅片10。不同列的翅片10、同一排的翅片10分体设置，方便扁管20的接插，不同列的翅片10且同一排的翅片10朝向相同，使得第二凸起16都靠近迎风侧，利于排水。
请参见图7及图9，不同列且同一排的翅片10上的接插槽11交错设置，使得前一列翅片10上的接插槽11的后方对应的是翅片10，扁管20内的介质不仅能够利用接插槽11两侧的翅片10换热，还能够利用扁管20后方的翅片10换热，充分利用翅片10加强换热效果。
在一些实施例中，不同列且同一排的翅片10上的接插槽11的中心点连线形成等边三角形，举个例子，第一列的第一排的其中一个接插槽11，在翅片10的长度方向上刚好位于第二列的第一排的相邻两个接插槽11的正中间。如此设置，能够保证前一列扁管20的后方的两侧都能够利用翅片10加强换热，进一步加强换热效果。
在本实施例中，扁管20为两列，翅片10也为两列，弯管50位于扁管20远离分配器30的一端，微通道换热器100形成U型。在其他实施例中，扁管20还可为三列、四列或四列以上，在扁管20的两端都设置弯管50，微通道换热器100也可形成L型、V型等。
在另一些实施例中，翅片10为多列，每排翅片10包括多列间隔设置的接插槽11，沿着微通道换热器100的高度方向，同一列翅片10上的接插槽11交错设置。
需要说明的是，通过使得翅片10上的接插槽11交错设置，从而使得插设于接插槽11内的扁管20交错设置，进而提高扁管20的换热面积，以提升微通道换热器100的换热量。
在一些实施例中，参见图16，微通道换热器100还包括集流管60，集流管60连接于扁管20的出口，用于对介质进行集流。毛细管31的一端连接于分配器30，另一端连接于扁管20，扁管20的出口连接于集流管60，通过分配器30分配制冷剂，代替进口集流管60，能够简化工艺。
在一些实施例中，扁管20为多列，最后一列的扁管20连接集流管60。在本实施例中，第二列扁管22连接集流管60，介质从第一列扁管21进入，经弯管50转弯进入第二列扁管22，再流入集流管60中。在其他实施例中，若扁管20为三列，则集流管60连通第三列扁管。如此设置，通过弯管50实现介质的多流程，集流管60只需要对介质做最后的汇集，而无需兼顾介质的转向，则集流管60无需设置隔板，简化集流管60的工艺。
在另一些实施例中，扁管20为一列，翅片10也为一列，扁管20的一端连接通过转接管40连接分配器30，另一端连接集流管60。在工作过程中，介质从分配器30进入，经毛细管31均匀分配至各根扁管20中，经翅片10与外界进行热交换，换热后从集流管60集中流出。
当微通道换热器100的扁管20为单列时，扁管20的一端通过转接管40及毛细管31连接于分配器30，另一端连接于集流管60；当微通道换热器100的扁管20为多列时，第一列扁管20的一端通过转接管40及毛细管31连接于分配器30，另一端连接于转接管40，最后一列的扁管20的出口连接于集流管60。
本申请的微通道换热器100，其扁管20的一端通过毛细管31及转接管40连接分配器30代替集流 管60，能够简化工艺。
在一些实施例中，分配器30和集流管60均安装在扁管20远离弯管50的一端，以提高换热器的结构布局紧凑性。分配器30包括分配头32以及与分配头32连接的多个毛细管31，分配头32具有多个分液孔，多个分液孔与多个毛细管31一一对应地设置，以使经各个分配孔分配口的流体经相应的毛细管31进入对应的扁管20内进行换热。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请的专利保护范围应以所附权利要求为准。
