具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚， 下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
本实施例提供一种热交换器，如图1和图2所示，该热交换器包括由上至下依次设置的第一集流管1、第二集流管2以及多排换热管3，其中：
可参照图3，上述第一集流管1包括第一主板11和第二主板12，第二主板12位于第一主板11的下方，第一主板11与第二主板12合围形成上述第一集流管1。可以理解的是，第一主板11和第二主板12可以是一个部件的两个部分，也可以是两个单独的部件拼接成的一个整体，可选地，第二主板12与第一主板11通过钎焊固定在一起。
上述第一主板11包括至少一个中间筋111，该中间筋111支撑于第二主板12，并能够将第一主板11分隔成若干通槽112，通槽112的延伸方向与第一集流管1的长度方向平行，其中每个通槽112与第二主板12形成一个流通腔，相邻的流通腔并列设置，且并列的方向垂直于第一集流管1的轴向。本实施例中，上述通槽112的截面形状可以是半圆形、半椭圆形、矩形等形状，还可以是其它能够形成通槽112形状。且每个通槽112的容积大小可以相同，也可以不同。
至少一个上述流通腔形成第一流道10，至少一个上述流通腔形成第二流道20，需要说明的是，本实施例中，上述第一流道10连通有第一流通口6，第二流道20连通有第二流通口7，热交换器作为冷凝器时，高温气态换热介质能够从第一流通口6进入第一流道10，并在换热管3内流通换热后，经第二流道20流出第二流通口7(此时换热介质为液态或气液混合态)。热交换器作为蒸发器时，液态换热介质能够从第二流通口7进入第二流道20，并在换热管3内流通换热后，经第一流道10流出第一流通口6(此时换热介质为气态)。上述第一流道10的总容积(即所有第一流道10的容积之和)大于第二流道20的总容积(即所有第二流道20的容积之和)，该结构的设置，能够使得换热所需的换热介质在热交换器中的流动速率较高。
本实施例中，可选地，上述第一流道10至少设置有两个，第二流道20至少设置有一个，且至少两个第一流道10全部位于第二流道20的同一侧，进而便于换热介质进入。
进一步地，上述至少两个第一流道10之间可以相互独立不连通，如图4所示，此时第一流通口流通换热介质会被相邻两个第一流道10之间的中间筋111分流，并各自进入对应的第一流道10内。
也可以在相邻两个第一流道10之间的中间筋111开设孔或开口113(如图5所示的开口113)，使得相邻两个第一流道10连通，此时第一流通口换热介质会先被相邻两个第一流道10之间的中间筋111分流，随后进入到各自对应的第一流道10内的换热介质会通过中间筋111开设的孔或开口113流入相邻的第一流道10内。
可参照图6，上述第二主板12可以成U字形结构，上述第一主板11置于第二主板12的U字形内部，即形成第二主板12包覆第一主板11的结构，随后通过钎焊将第二主板12和第一主板11固定连接。可以理解的，上述第二主板12也可以是板状结构，此时第一主板11直接支撑在第二主板12上，并且通过钎焊将两者固定。
如图6所示，在上述第二主板12上开设有若干排第一换热管孔121，该第一换热管孔121用于供换热管3的穿入，并在该第一换热管孔121处对换热管3进行钎焊，使得换热管3与第二主板12固定且于连接处密封。本实施例中，上述第一换热 管孔121的排数与换热管3的排数相同，且每个第一换热管孔121均有一个换热管3穿入。通过该第一换热管孔121，能够使得第一流道10内的换热介质流入换热管3或使得第一流道10内的换热介质流入换热管3，以及使得换热管3内的换热介质流入第二流道20或第二流道20内的换热介质流入换热管3。本实施例中，在第一换热管孔121的周边设置有翻边122，翻边122沿远离第一主板11的方向延伸，该翻边122能够增加与换热管3的接触面积，使得换热管3与第二主板12的焊接面更大，焊接后的强度更大。在其他实施例中，翻边还可以沿靠近第一主板11的方向延伸。
可选地，上述第一换热管孔121可以是长型孔，也可以是圆形孔或矩形孔，其形状由于其装配的换热管3的形状决定。本实施例中，第一换热管孔121为长型孔，相应的，换热管3为扁管，上述翻边122的高度与换热管3厚度相关，其高度为换热管3厚度的0.7-1.3倍。
本实施例中，上述换热管3设置有若干排，每个第一流道10和每个第二流道20分别对应设置一排换热管3，换热管3的具体排数与形成第一流道10和第二流道20的通槽112的个数的总和相同。可选地，第一流道10设置有两个，第二流道20设置有一个，即换热管3设置有三排。
这里，需要理解的是，本实施例中每个第一流道10和每个第二流道20分别对应设置一排换热管3，当然，也可以多个第一流道10对应设置一排换热管3，也可以一个第一流道10对应设置多排换热管3；或者也可以多个第二流道20对应设置一排换热管3，也可以一个第二流道20对应设置多排换热管3，不影响换热介质的流动即可，本申请不予限制。
本实施例中，换热介质在第一流道10中的密度小于第二流道20中的密度，相同量的换热介质，在第一流道10中的体积大于在第二流道20中的体积，上述第一流道10的总容积大于第二流道20的总容积，且第一流道10连通的换热管3的数量多于第二流道20连通的换热管3的数量，该结构的设置，能够使得换热所需的换热介质在热交换器中的流动速率较高。
如图1所示，热交换器还包括端盖8，其中第一流通口6和第二流通口7设置于端盖8上。
可以理解的是，上述第一流通口6可以设置为一个，此时该第一流通口6连通所有的第一流道10。该第一流通口6还可以设置多个，此时每个第一流通口6分别连通一个第一流道10。
本实施例中，上述第二集流管2与换热管3未连接第一流道10和第二流道20的一端连通，即换热管3的两端分别连接于第一集流管1和第二集流管2。
如图2以及图7所示，本实施例的第二集流管2包括焊接于一体的第三主板21和第四主板22，第三主板21位于第四主板22的下方，该第三主板21和第四主板22均为平板结构，且参照图7，上述第三主板21的顶面为平面，第四主板22的底面也为平面。通过均为平板结构的第三主板21和第四主板22，使得本实施例的第二集流管2的结构更加紧凑。
在第三主板21上开设有凹槽211，该凹槽211能够与第四主板22合围形成第三通道30。具体的，上述凹槽211需满足容纳所有换热管3，本实施例凹槽211的宽度大于最外侧的两排换热管3之间的最大距离。上述凹槽211的深度为第三主板21厚度的1/3-1/2。
本实施例中，上述第四主板22上设有若干排第二换热管孔221，每个第二换热管孔221均对应一个换热管3设置，上述若干排换热管3的一端穿过该第二换热管孔221，且与第三通道30连通。上述第二换热管孔221采用外翻边(具体是向远离第三主板21的方向翻边)的结构，能够增大与换热管3的接触面积，进而增加第二 换热管孔221与换热管3的连接强度。本实施例中，上述第二换热管孔221与换热管3之间采用钎焊连接起来。本实施例中，上述第二换热管孔221的长度大于换热管3缩口宽度，第二换热管孔221的宽度大于换热管3厚度，第二换热管孔221翻边的高度为换热管3厚度的0.7-1.3倍。在其他实施例中，第二换热管孔221的翻边也可以靠近第三主板21的方向延伸。
可以理解的，本实施例的第二集流管2，也可以是直接在第四主板22上开设凹槽211，第三主板21仅为一个平板结构，两者之间形成上述第三通道30。
本实施例的上述热交换器作为冷凝器时的运行原理如下：
首先，气态的换热介质通过第一流通口6进入，随后分流至第一集流管1的总容积相对较大的第一流道10内，此时换热介质会进入与第一流道10连通的换热管3内，并在此过程中与其他介质换热，最终换热介质经与第一流道10连通的换热管3流入第二集流管2的第三通道30内，并经第三通道30流入与第二流道20连通的换热管3内，随后在与第二流道20连通的换热管3内流入第二流道20，并在此过程中进一步与其他介质(例如空气)换热，最终经第二流通口7流出(此时换热介质为液态或气液混合状态)，完成换热过程。
本实施例的上述热交换器作为蒸发器时的运行原理如下：
首先液态或者气液混合状态的换热介质通过第二流通口7进入第一集流管1的总容积相对较小的第二流道20内，此时换热介质会进入与第二流道20连通的换热管3内，并在此过程中与其他介质换热，换热介质经与第二流道20连通的换热管3流入第二集流管2，并经第三通道30流入与第一流道10连通的换热管3内，随后在与第一流道10连通的换热管3内流入第一流道10，并在此过程中进一步与其他介质(例如空气)换热，最终经第一流通口6流出(此时换热介质为气态)，完成换热过程。
本实施例的上述热交换器，第一流道10内流通的为气态换热介质，第二流道20内流通的为液态或气液混合态的换热介质，由于第一流道10的总容积大于第二流道20的总容积，连通于第一流道10的换热管3的流通通道的总容积大于连通于第二流道20的换热管3的流通通道的总容积，热交换器内的换热介质的量一定时，能够使得气态换热介质在总容积较大的流通通道内流动，而液态或气液混合态的换热介质在总容积较小的流通通道内流动，进而能够使得换热所需的换热介质的流动速率较高，换热性能得到提高。而且上述热交换器的结构强度更高，能够适用于高压力换热介质。
实施例二
本实施例与实施例一的区别在于本实施例的第一集流管1的结构有所不同，具体的，如图8和图9所示，本实施例的第一集流管1包括包括第一主板11、第二主板12以及第一中间板13，其中第一主板11以及第二主板12的结构与实施例一所述的第一主板11以及第二主板12的结构相同，区别在于，本实施例的第一主板11的中间筋111是支撑于第一中间板13上，第二主板12包覆第一中间板13以及第一主板11，三者通过钎焊固定连接，并形成第一流道10和第二流道20。
具体的，本实施例的第一中间板13上开设有若干排第一条形孔131，该第一条形孔131的排数与第一流道10和第二流道20的数量之和相同，第一条形孔131与第一换热管孔121一一对应设置，即每排第一条形孔131均对应一个第一流道10或第二流道20。上述第一主板11的通槽112、第一条形孔131以及第二主板12之间形成第一流道10和第二流道20。通过在第一主板11和第二主板12之间设置第一中间主板13，且三者之间钎焊固定连接，增加了第一集流管1整体结构的强度。
上述第二主板12的第一换热管孔121均对应一个第一条形孔131，上述换热管3的一端密封穿过第一换热管孔121且容纳于第一条形孔131内。
本实施例的其它结构与实施例一的所述结构均相同，且本实施例的热交换器的运行原理与实施例一的也相同，故不再赘述。
实施例三
本实施例与实施例一的区别在于，本实施例的第二集流管2的结构有所不同，具体的，如图10和图11所示，本实施例的第二集流管2包括包括第三主板21、第四主板22以及第二中间板23，其中第三主板21以及第四主板22的结构与实施例一所述的第三主板21以及第四主板22的结构相同，区别在于，本实施例的第四主板22与第二中间板23以及第三主板21，三者之间通过钎焊固定连接，并形成第三通道30。
具体的，本实施例的第二中间板23上开设有若干排第二条形孔231，该第二条形孔231的排数与换热管3的排数相同，第二条形孔231与第二换热管孔221一一对应设置，即每个第二条形孔231均对应一个换热管3。上述第三主板21的凹槽211、第二条形孔231以及第四主板22之间形成第三通道30。通过在第三主板21和第四主板22之间设置第二中间板23，且三者之间钎焊固定连接，增加了第二集流管2整体结构的强度。
上述第四主板22的第二换热管孔221均对应一个第二条形孔231，上述换热管3未连接第一集流管1的一端密封穿过第二换热管孔221且容纳于第二条形孔231内。本实施例的其它结构与实施例一的所述结构均相同，且本实施例的热交换器的运行原理与实施例一的也相同，故不再赘述。
实施例四
本实施例与实施例二的区别在于，本实施例的第二集流管2的结构有所不同，具体的，如图12所示，本实施例的第二集流管2的结构与实施例三所述的结构相同，即本实施例的第二集流管2包括第二中间板23。具体的，本实施例的其它结构与实施例二的所述结构均相同，且本实施例的热交换器的运行原理与实施例二的也相同，故不再赘述。
实施例五
本实施例在实施例一的基础上，在第一集流管1上增加了第一隔板4的结构，以实现四流程换热的结构。具体的，如图13和图14所示，本实施例的第一集流管1的第一流道10和第二流道20均包括第一端和第二端，其中第一流道10的第一端与第二流道20的第一端位于同一侧(图13所示的左侧)，第一流道10的第二端与第二流道20的第二端位于同一侧(图13所示的右侧)。且上述第一流道10的第一端与第二流道20的第一端连通(可采用在第一流道10和第二流道20之间的中间筋111上开孔或开口的方式实现连通)，第一流通口6连通于第一流道10的第二端，第二流通口7连通于第二流道20的第二端。
上述第一流道10的第一端和第二端之间、第二流道20的第一端和第二端之间均设有第一隔板4，其中第一流道10的第一端和第二端之间的第一隔板4用于将第一流道10隔断，第二流道20的第一端和第二端之间的第一隔板4用于将第二流道20隔断；在第一主板11的宽度方向开设一组隔板孔(图中未示出)，在每个隔板孔上插接第一隔板4，通过第一隔板4的设置，可以将上述第一流道10和第二流道20均分成第一段和第二段，能够实现换热介质的多流程运行。需要说明的是，靠近 第一流通口6和第二流通口7的第一段不相连通，远离第一流通口6和第二流通口7的第二段相连通，由此能够实现上述四流程换热。
上述第三通道30包括两个相互独立的流通通道，其中一个流通通道与所有第一流道10连通的换热管3连通，另一个流通通道与第二流道20连通的换热管3连通。也就是说，在本实施例中，可参照图14，上述第二集流管2的第三主板21的凹槽211开设有两个，每个凹槽211与第二主板12之间均形成一个流通通道。本实施例中，将两个流通通道设置第一端和第二端，其中两个流通通道的第一端位于同一侧，两个流通通道的第二端位于另一侧。且上述流通通道的第一端与第一流道10的第一端以及第二流道20的第一端均位于热交换器的同一侧，流通通道的第二端与第一流道10的第二端以及第二流道20的第二端均位于热交换器的另一侧。
本实施例的上述热交换器作为冷凝器时的运行原理如下：
首先，换热介质通过第一流通口6进入第一流道10的第二段(位于第一隔板4和第一流通口6之间)，此时换热介质进入第一流程，换热介质进入与第一流道10的第二段连通的换热管3，并沿换热管3流动，此时其他介质(例如空气)与换热介质换热；换热介质沿着换热管3进入第三通道30中与该换热管3对应的流通通道的第二段，并随后流至该流通通道的第一段；随后换热介质进入与该第一段连通的换热管3内流动，此时进入第二流程，第二流程中换热介质进一步与其他介质换热，并最终流入第一流道10的第一段内。
之后，换热介质经第一流道10的第一段流入第二流道20的第一段，并流入与第二流道20的第一段连通的换热管3内，流动的过程中，换热介质再次与其他介质换热，此为第三流程；此时，换热介质流入到另一个流通通道(即与第二流道20对应的流通通道)的第一段，并流入至该流通通道的第二段，随后经该流通通道的第二段进入第二流道20的第二段连通的换热管3，此时即为第四流程，换热介质流动的过程中与其他介质换热，并最终流入第二流道20的第二段，随后经与第二流道20第二段连通的第二流通口7流出，完成一次换热过程。
本实施例的热交换器通过设置第一隔板4，其能够形成四流程换热方式，进一步提高了换热效果。
实施例六
本实施例与实施例五的区别在于，本实施例的第一集流管1包括第一中间板13，如图15所示，此时第一中间板13位于第一隔板4的一侧设置第一条形孔131，位于第一隔板4的另一侧设置第三条形孔132，上述第一条形孔131位于第一隔板4靠近第一流通口6的一侧，第三条形孔132远离第一流通口6设置。上述第三条形孔132能够将第一流道10和第二流道20连通起来，进而实现换热介质从第一流道10进入到第二流道20。
当然，可以理解的，本实施例的第二集流管2还可以包括第二中间板23，该第二中间板23的结构以及安装位置与实施例三所述的第二中间板23相同，不再赘述。
本实施例的热交换器的其余结构与实施例五均相同，且本实施例的热交换器的运行原理与实施例五的也相同，故不再赘述。
实施例七
本实施例在实施例五的基础上，在第二集流管2的两个流通通道上增加了第二隔板5的结构，且更改了凹槽211的结构，以实现六流程的换热。具体的，如图16和图17所示，本实施例的第二集流管2的第三通道30包括第一流通通道、第二流通 通道以及第三流通通道，其中第一流通通道与第二流通通道之间由第二隔板5分隔，第一流通通道与第三流通通道之间也由第二隔板5分隔，以使得三个流通通道之间相互独立。
本实施例中，如图17所示，凹槽211可以包括第一凹槽212、第二凹槽213以及第三凹槽214，上述第二隔板5置于第一凹槽212和第二凹槽213之间，同时也置于第一凹槽212和第三凹槽214之间，通过第二隔板5、第四主板22以及上述三个凹槽，能够形成上述第一流通通道、第二流通通道和第三流通通道。
本实施例中，上述第一流通通道分别连通于第一流道10的第一端和第二隔板5之间的换热管3以及第二流道20的第一端和第二隔板5之间的换热管3。
上述第二流通通道连通于第一流道10的第二端和第二隔板5之间的换热管3，第三流通通道连通于第二流道20的第二端和和第二隔板5之间的换热管3。
本实施例中，可以在第三主板21上开设对应的隔板孔(图中未示出)，上述第二隔板5能够插接在隔板孔内，以形成三个流通通道。
本实施例中，在水平方向上，上述第二隔板5设置于第一隔板4远离第一流通口6的一侧，使得第一集流管1位于第一隔板4第一侧(图16所示的右侧)的通道(也就是第一流道10的第一端以及第二流道20的第一端)的长度大于第一流通通道的长度。通过上述结构，能够实现热交换器的六流程的换热结构。
本实施例的其余结构与实施例五均相同，故在此不再赘述。
下面对本实施例的上述热交换器作为冷凝器时的运行原理加以说明：
首先，换热介质通过第一流通口6进入第一流道10的第二端(图17所示的右侧)与第一隔板4之间的通道中，换热介质进入与第一流道10的第二端与第一隔板4之间的通道连通的换热管3内，并沿此部分换热管3流动，此时换热介质与其他介质(例如空气)进行换热，此为第一流程；
换热介质进入第二流通通道中，并且由于第二隔板5的作用，换热介质会流入位于第一隔板4和第二隔板5之间且与第一流道10连通的换热管3中，再次与其他介质换热，此为第二流程；
随后换热介质流入与第一流道10的第一端(图17所示的左侧)与第一隔板4之间的通道内，接着换热介质进入与第一流道10的第一端与第二隔板5之间的通道连通的换热管3内，再次与其他介质换热，此为第三流程；
换热介质进入第一流通通道内，之后换热介质沿位于第二流道20的第一端与第二隔板5之间的通道连通的换热管3流动，与其他介质换热，此为第四流程；
换热介质流入到第二流道20的第一端(图17所示的左侧)与第一隔板4之间的通道内，之后换热介质流入与位于第一隔板4和第二隔板5之间且与第二流道20连通的换热管3内，在此过程中换热介质与其他介质换热，即第五流程；
换热介质流入第三流通通道内，之后换热介质进入到第二流道20的第二端(图17所示的右侧)与第一隔板4之间的通道所连通的换热管3内，并进一步与其他介质换热，最终进入到第二流道20的第二端(图17所示的右侧)与第一隔板4之间的通道内，并通过第二流通口7流出，完成一次换热过程，此为第六流程。
本实施例的热交换器作为蒸发器时，换热介质从第二流通口7流入，从第一流通口6流出，换热介质的流动方向与热交换器作为冷凝器时的换热介质的流动方向相反，故不再赘述。
本实施例的上述热交换器，能够实现六流程的换热过程，进一步提高了换热性能。
实施例八
本实施例与实施例七的区别在于，本实施例的第一集流管1包括第一中间板13，如图18所示，该第一中间板13的结构与实施例二所述的第一中间板13的结构相同。本实施例的热交换器的其余结构与实施例七均相同，且本实施例的热交换器的运行原理与实施例五的也相同，故不再赘述。

在本实施例中，上述第一筋103可以是条形筋，具有平坦的端面，第一配合面107a为平坦表面，第一筋103上该平坦的表面与第一配合面107a的平坦表面贴合后，增大了焊接面积。
作为一种可能的实现方式，第二主板12还包括第二平直段108，第二平直段108与第二弯曲段105或第一平直段107相连，第二平直段108包括第二配合面108a。第一主板11还包括第二筋109，可选的，第二筋109也可以是条形筋，其端面也可以是平坦的端面，第二筋109的一端连接相邻两个第一弯曲段104，另一端的端面与第二配合面108a贴合。

上述第二筋109的设置能够起到进一步增强集流管100的强度的作用，以便承受冷媒的压力。可选的，第二筋109可以以第一筋103为中心轴对称设置。每个第二筋109将上述腔室130a分为两个子腔室。当然，第二筋109也可以相对于第一筋103为非对称设置，均可达到进一步增强集流管100强度的作用。下文将会以四流程和三流程为例进行说明。
作为一种可能的实现方式，如图26所示，第一筋103和/或第二筋109设置有第三筋110。这里需要理解的是，第三筋110为第一筋103和/或第二筋109朝远离自身的方向延伸形成，例如第一筋103设于第一主板11，第三筋110为第一筋103远离第一主板11的端部朝第二主板12的方向延伸形成。
可选的，第三筋110可以是条形筋，也可以是三角形筋或其他形态结构；第三筋110可以设置于第一筋103的端部的任意位置，和/或设置于第二筋109的端部的任意位置。第一平直段107和/或第二平直段108设置配合孔108b(参照图27)，第三筋110与配合孔108b固定。第三筋110的设置能够进一步提高集流管100的强度。可选的，第三筋110在与配合孔108b配合后，第三筋110穿过配合孔108b的部分可以进一步扭转固定，提升了第一主板11和第二主板12的连接强度。
本实施例以第三筋110设置于第二筋109为例，如图23和图25所示，第二筋109 上设置有一定厚度和高度的第三筋110，第三筋110的厚度W1可以是第二筋109厚度W2的1/4-1/2，这样，在第三筋110与配合孔108b配合后，第二筋109的宽度足够大，能够起到一定的限位作用，以保证第三筋110与配合孔108b的连接可靠。第三筋110的高度H可以是2-9mm，这样，当第三筋110从配合孔108b穿出后，露出的长度更能方便使用工具来夹持以进行扭转，扭转后的第三筋110进一步加强了第一主板11和第二主板12的连接强度。
通过第三筋110与第二主板12的配合孔108b紧密连接，起到固定及定位且连接第一主板11和第二主板12的作用，提高了第一主板11和第二主板12的连接可靠性。

图27为本申请实施例所提供的第三种集流管中第二板的结构示意图，图28为本申请实施例所提供的第三种集流管中第一板的结构示意图。如图27、图28所示，作为一种可能的实现方式，第二主板12设置有隔板槽124，集流管100还包括第一隔板4(参照图21、图33)，第一隔板4固定于隔板槽124。参照图28，第一主板11的第一筋103设置有连通槽103a，连通槽103a在第一隔板4的一侧，相邻的腔室130a在连通槽103a处连通，在第一隔板4的另一侧，腔室130a相互隔离。本领域技术人员可以理解，也可以通过设置连通孔将腔室130a连通，本申请并不限于上述连通槽103a。
第一隔板4可以有多组，通过多组第一隔板4与隔板槽124的配合，可以将上述腔室130a沿集流管100的长度方向分为多个子腔室，多个子腔室能够实现冷媒的多流程运行。第一隔板4也可以是一体式的结构，整体与隔板槽124配合，整体式的第一隔板4也能将腔室130a沿集流管100的长度方向分为多个子腔室，多个子腔室能够实现冷媒的多流程运行，下文将会具体描述多流程运行的过程。
如图27所示，在第一主板11或第二主板12上还可以设置有容置槽126，可选的，该容置槽126可以通过冲床冲压获得，也可以通过铸造等方式一体成型。容置槽126的形状和大小和换热管3的缩口部43的形状大小相匹配。具体而言，容置槽126可以是例如具有矩形形状的开口，也可以是腰形形状的开口，换热管3通常为扁管，可参照图31和图32，扁管状的换热管3具有缩口部43，缩口部43伸入至上述容置槽126内。
如图27所示，在本实施例中，容置槽126设置于第二主板12，对应地，第一主板11上的第二筋109可以开设用于避让换热管3端部的缺口，该缺口的宽度与换热管 3的缩口部43的厚度匹配，使缩口部43的至少部分能够容置于缺口。当换热管3的缩口部43的至少部分伸入至缺口中时，伸入的深度需满足缩口部43的端部不会抵碰到缺口的内壁，不影响冷媒流动即可。可以理解的是，也可以在第二主板12设置容置槽，在第二主板12设置第二筋109和缺口，在此不作具体限定。
在本实施例中，一个缺口容纳一个换热管3的端部，当然，也可以一个缺口容纳两个及两个以上的换热管3的端部，此时缺口的宽度大于或者等于两个及两个以上的换热管3之间的间距及全部换热管3的厚度之和，只要满足所有换热管3缩口部43的端部不会抵碰到缺口的内壁，不影响冷媒流动即可。

首先，冷媒通过进口进入到第一集流管1的位于第一隔板4与第一端A1之间的子腔室131c和子腔室131d(如图24)，此时，如图20和图21所示，冷媒进入第一流程，冷媒沿着与第一隔板4与第一端A1之间的子腔室131c和子腔室131d连通的 后排管42向下流动，流至第二集流管2位于第一隔板4与第三端A3之间的的子腔室131c和子腔室131d，空气与冷媒进行换热，冷媒蒸发吸热；需要说明的是，第二集流管2未设置第一隔板4，第一隔板4与第三端A3之间指的是，第一隔板4在第三集流管3上的投影与第三端A3之间。
然后冷媒进入第二集流管2位于第一隔板4与第四端A4之间的子腔室131c和子腔室131d，并进入第二流程；需要说明的是，第二集流管2未设置第一隔板4，第一隔板4与第三端A3之间指的是，第一隔板4在第三集流管3上的投影与第三端A3之间。冷媒沿着与第一隔板4与第四端A4之间的子腔室131c和子腔室131d连通的后排管42向上流动并继续蒸发吸热；
接下来，冷媒流至第一集流管1位于第二端A2和第一隔板4之间的子腔室131c和子腔室131d；由于连通槽103a的存在，冷媒从第一集流管1位于第二端A2和第一隔板4之间的子腔室131c和子腔室131d流入到第一集流管1位于第二端A2和第一隔板4之间的子腔室131a和子腔室131b，然后进入第三流程，冷媒沿着与第二端A2和第一隔板4之间的子腔室131a和子腔室131b连通的前排管41向下流动，流至位于第二集流管2中与第四端A4和第一隔板4之间的子腔室131a和子腔室131b；
随后，冷媒流入到第二集流管2位于第三端A3和第一隔板4之间的子腔室131a和子腔室131b，进入第四流程，冷媒沿着与第二集流管2中与第三端A3和第一隔板4之间的子腔室131a和子腔室131b连通的前排管41向上流动，并从与第一集流管1位于第一端A1和第一隔板4之间的子腔室131a和子腔室131b连通的出口流出。
本申请实施例所提供的热交换器作为冷凝器时的四流程运行原理如下：
首先，冷媒通过进口进入第一集流管1的位于第一端A1和第一隔板4之间的子腔室131a和子腔室131b，进入第一流程，冷媒沿着与第一隔板4与第一端A1之间的子腔室131a和子腔室131b相通的前排管41向下流动，流至第二集流管2位于第一隔板4与第三端A3之间的子腔室131a和子腔室131b，冷媒降温液化；需要说明的是，第二集流管2未设置第一隔板4，第一隔板4与第三端A3之间指的是，第一隔板4在第三集流管3上的投影与第三端A3之间。
然后冷媒流至第二集流管2位于第一隔板4与第四端A4之间的子腔室131a和子腔室131b，并进入第二流程；需要说明的是，第二集流管2未设置第一隔板4，第一隔板4与第四端A4之间指的是，第一隔板4在第三集流管3上的投影与第四端A4之间。冷媒沿着与第一隔板4与第四端A4之间的子腔室131a和子腔室131b相通的前排管41向上流动，流动至第一集流管1与第一隔板4与第二端A2之间的子腔室131a和子腔室131b。由于连通槽103a的存在，冷媒由第一集流管1与第一隔板4与第二端A2之间的子腔室131a和子腔室131b流入到第一集流管1与第一隔板4与第二端A2之间的子腔室131c和子腔室131d；
接下来，进入第三流程，冷媒沿着与第一集流管1与第一隔板4与第二端A2之间的子腔室131c和子腔室131d相通的后排管42向下流动，并降温液化；
最后，冷媒流到位于第二集流管2中第四端A4与第一隔板4之间的子腔室131c和子腔室131d，进入第四流程，冷媒沿着与第四端A4与第一隔板4之间的子腔室131c和子腔室131d相通的后排管42向上流动，从第一集流管位于第一端A1和第一隔板4 之间的子腔室131c和子腔室131d连通的出口流出。
本实施例中，如图29至图31所示，端盖8包括本体141和形成于本体141的第一开口142。
第一开口142可以是圆形开口，也可以是其他形状，直接形成于本体141，也可以在本体141上连接管体，管体的通道即能形成该第一开口142。
本体141还包括第二腔143和第一槽部144，第一槽部144位于第一开口142和第二腔143之间，第一槽部144包括靠近第一开口142的第一底壁145，第一底壁145包括第三开口145a，第三开口145a连通第一开口142与第二腔143，第二腔143与第一集流管1的内腔或第二集流管2的内腔连通，第一开口142相比第二腔143远离第一集流管1的内腔或第二集流管2的内腔，第一槽部144的过流面积大于第三开口145a的过流面积。这里的过流面积，指的是单位时间内通过某一过流断面的流体体积。举例而言，本实施例中，第一槽部144的过流面积指的是单位时间内通过第一槽部144的横断面的流体体积。
第一开口142可以作为端盖8的冷媒进口，也可以作为冷媒出口，在此不作限定。当第一开口142作为进口时，冷媒从第一开口142经过第三开口145a进入到第一槽部144时，由于第一槽部144的过流面积大于第三开口145a的过流面积，这样在冷媒进入的过程中，可以降低进入到集流管100的第一腔130内的冷媒对集流管100造成的冲击，可以降低集流管100的耐压需求。
当第一开口142作为出口时，冷媒从第一槽部144进入到第四开口145a时，也能使冷媒的流量更加均匀。
作为一种可能的实现方式，第一槽部144在沿着第一底壁145横向延伸方向的宽度大于第三开口145a在沿着第一底壁145横向延伸方向的宽度。本实施例中，第一槽部144可以是腰形槽，第三开口145a可以是圆孔，腰形槽的长轴尺寸大于圆孔的孔径，可选的，腰形槽的短轴尺寸可以等于圆孔的孔径，当然，腰形槽的短轴尺寸也可以大于或者小于圆孔的孔径，只要不影响第三开口145a连通第一开口142和第二腔143的作用即可。可选的，第三开口145a的中心与第一槽部144的中心重合，冷媒从第三开口145a中流出时，能够均匀的向两侧分流，从而达到均匀分流的效果。当然，第一槽部144也可以是其他形状，例如矩形、圆形等，第三开口145a也可以是其他形状的孔，例如异形孔或椭圆形孔等。
作为一种可能的实现方式，本体141还包括第一通道145b，第一通道145b为第三开口145a沿第二腔143向第一开口142的方向延伸形成。第一通道145b位于第一开口142和第一槽部144之间，第一通道145b分别与第一开口142和第一槽部144连通，第一通道145b在沿着第一底壁145横向延伸方向的宽度小于第一槽部144在沿着第一底壁145横向延伸方向的宽度。
以第一开口为圆形，第一通道145b为圆形通道，外部管路为圆管为例，该第一通道145b的内径可以与第三开口145a的孔径大小相同，外部用于输入冷媒的管路插入至第一开口142，外部管路的内径与该第一通道145b的内径相等，冷媒进入后，经过第一通道145b先形成流量较小的状态，再经过第三开口145a进入到第一槽部144，形成分流，进一步降低了冷媒对集流管100的冲击。
在上述实施例的基础上，本体141形成有第二开口146，第二开口146可以是圆形开口，也可以是其他形状，直接形成于本体141，也可以在本体141上连接管体，管体的通道即能形成该第二开口146。
本体141还包括第二槽部147，第二槽部147包括靠近第二开口146的第二底壁148，第二底壁148包括第四开口148a，第四开口148a连通第二开口146与第二腔143，第二槽部147的过流面积大于第四开口148a的过流面积。这里的过流面积，指的是单位时间内通过某一过流断面的流体体积。举例而言，本实施例中，第二槽部147的过流面积指的是单位时间内通过第二槽部147的横断面的流体体积。
该第二开口146可以作为端盖8的冷媒进口，也可以作为冷媒出口，在此不作限定。当第二开口146作为进口时，冷媒从第二开口146经过第四开口148a进入到第二槽部147时，由于第二槽部147的过流面积大于第四开口148a的过流面积，这样在冷媒进入的过程中，能够降低冷媒的瞬间压力，这样，可以降低进入到集流管100的第一腔130内的冷媒对集流管100造成的冲击。
当第二开口146作为出口时，冷媒从第二槽部147进入到第四开口148a时，也能使冷媒的流量更加均匀。
作为一种可能的实现方式，第二槽部147在沿着第二底壁148横向延伸方向的宽度大于第四开口148a在沿着第二底壁148横向延伸方向的宽度。本实施例中，第二槽部147可以是腰形槽，第四开口148a可以是圆孔，腰形槽的长轴尺寸大于圆孔的孔径，可选的，腰形槽的短轴尺寸可以等于圆孔的孔径，当然，腰形槽的短轴尺寸也可以大于或者小于圆孔的孔径，只要不影响第三开口连通第一开口和第二腔的作用即可。可选的，第三开口的中心与第一槽部的中心重合，冷媒从第四开口148a中流出至第二槽部147时，能够均匀地向两侧分流，从而达到均匀分流的效果。当然，第二槽部147也可以是其他形状，例如矩形、圆形等，第四开口148a也可以是其他形状的孔，例如异形孔或椭圆形孔等。
作为一种可能的实现方式，本体141还包括第二通道148b，第二通道148b为第四开口148a沿第二腔143向第二开口146的方向延伸形成。第二通道148b位于第二开口146和第二槽部147之间，且第二通道148b分别与第二开口146和第二槽部147连通，第二通道148b在沿着第二底壁148横向延伸方向的宽度小于第二槽部147在沿着第二底壁148横向延伸方向的宽度。
以第二开口为圆形，第二通道为圆形通道，外部管路为圆管为例，该第二通道148b的内径可以与第四开口148a的孔径大小相同，当第二通道148b用作输入通道时，外部用于输入冷媒的管路插入至第二开口146，外部管路的内径与该第二通道148b的内径相等，冷媒进入后，经过第二通道148b先形成流量较小的状态，再经过第四开口148a进入到第二槽部147，形成分流，进一步降低了冷媒对集流管100的冲击。
当第二通道148b用作输出通道时，冷媒从第二槽部147进入到第二通道148b，也能使冷媒的流量更加均匀。
作为一种可能的实现方式，上述的第一槽部144与第二槽部147可以是以端盖8的中心线对称设置，这样能够使冷媒的分布更加均匀。同样地，第一通道145b与第二通道148b，第三开口145a与第四开口148a也以端盖8的中心线对称设置，以使冷媒 的分布更加均匀。
本实施例中，集流管100包括相连接的第一主板11和第二主板12；第一主板11和第二主板12之间形成第一腔130。第一主板11和/或第二主板12设置有第一筋103；第一腔130包括至少两个腔室130a，第一筋103设置于相邻的腔室130a之间。
该集流管100还包括本申请任意实施例提供的端盖8，端盖8封堵于第一腔130的一端，且第一开口142经过第一槽部144与一个腔室130a相通。
可以理解的是，集流管100可以包括一个仅具有第一开口142的端盖8，也可以包括同时具有第一开口142和第二开口146的端盖。当端盖同时具有第一开口142和第二开口146时，第一筋103抵接于本体141，第一筋103位于第一开口142和第二开口146之间，也位于第一槽部144和第二槽部147之间，防止第一开口142和第二开口146在端盖处连通。由于上述端盖8中，第一槽部144的过流面积大于第三开口145a的过流面积，这样使冷媒在流入集流管100的腔室130a的过程能进一步减缓冲击力。
如图28和图33所示，在本实施例中，第一隔板4到端盖8的距离小于第一筋103未开设连通槽103a部分的长度，以此提高第一隔板4处的密封性能。当然，这两部分的长度也可以相等，在此不作限定。在本实施例中，第一筋103未开设连通槽103a部分的长度尺寸可以大于第一筋103上开设连通槽103a部分的长度尺寸，当然，第一筋103未开设连通槽103a部分的长度尺寸也可以小于或者等于第一筋103上开设连通槽103a部分的长度尺寸，在此不作限定。图36为本申请实施例所提供的集流管的局部示意图，参照图34和图36所示，作为一种可能的实现方式，第一主板11和/或第二主板12包括第二筋109，腔室130a包括两个以上子腔室，第二筋109位于相邻的两个子腔室之间。
第一槽部144的宽度大于第一槽部144正对的第二筋109的宽度，冷媒从第一槽部144流出后，大部分冷媒不会垂直撞击到第二筋109，而是能够从第二筋109的两侧流入腔室130a，从而降低对第二筋109的撞击力。
作为一种可能的实现方式，第二筋109朝向端盖8的一端设置有第三槽109b，冷媒从第一槽部144流出后，第三槽109b能够起到避让的作用，进一步避免冷媒会直接冲击第二筋109的问题。
同样地，冷媒从腔室130a流出时，由于第三槽109b的设置，冷媒不会受到过大的阻力，也能顺利地流入到第二腔143，再从出口流出。
可以理解的是，第三槽109b可以如图36所示为方形槽，当然，也可以为U形槽或V形槽，也可以为其它异形槽，只要能起到避让的作用，避免冷媒会直接冲击第二筋109即可，本申请不予限制。

本体141包括上部本体141d和下部本体141e；上部本体141d包括与第一弯曲段 104对应设置的第三弯曲段141a；下部本体141e包括与第一平直段107和第二平直段108对应设置的第三平直段141b和与第二弯曲段105对应设置的第四弯曲段141c，第三平直段141b连接相邻两个第四弯曲段141c；第四弯曲段141c与第三弯曲段141a对应设置。
于本实施例中，端盖8与第一主板11、第二主板12配合时，上述端盖8的第三平直段141b能够与第一平直段107和第二平直段108贴合，而第三弯曲段141a能够与第一弯曲段104贴合，第四弯曲段141c能够与第二弯曲段105贴合。
