本申请要求2020年9月1日申请的，申请号为202021878547.9，发明名称为“组合式换热器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及制冷技术领域，特别是涉及一种组合式换热器。
背景技术
空调系统的主要组成部件包括压缩机、冷凝器、节流装置以及换热器，换热器起到与外界进行热交换的作用，现有换热器的集管采用竖直扁管连接，并通过将集管进行折弯，形成近似方形的换热器结构。
但有时集管折弯不当，易导致扁管变形，降低换热器的换热性能；同时，集管的折弯工艺要求高，且折弯段材料存在塑性变形，易造成表面损失，从而引起材料腐蚀造成泄露。
发明内容
有鉴于此，针对上述技术问题，有必要提供一种换热性能好、便于拆装且结构简单的组合式换热器。
为解决上述技术问题，本申请提供如下技术方案：
申请一种组合式换热器，该组合式换热器包括至少两个换热器芯体、第一连通件以及第二连通件，每个所述换热器芯体至少包括第一集流管、第二 集流管以及若干扁管；所述扁管竖直设置于所述第一集流管和所述第二集流管之间，所述第一连通件的两端分别连通相邻两个所述换热器芯体的所述第一集流管，所述第二连通件的两端分别连通相邻两个所述换热器芯体的所述第二集流管，且相邻两个所述换热器芯体布置在不同平面上。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，本申请提供一种组合式换热器100，该组合式换热器100应用于空调系统中，用以与外界进行热交换。在本实施例中，换热器芯体10为微通道换热器芯体10，当然，在其他实施例中，换热器芯体10还可为翅片式或者其他类型换热器芯体10。
请参阅图1，图1为本申请一实施方式中的组合式换热器100的示意图，该组合式换热器100包括至少两个换热器芯体10、第一连通件20以及第二连通件30，每个换热器芯体10至少包括第一集流管11以及第二集流管12，第一连通件20的两端分别连接相邻两个换热器芯体10的第一集流管11，流体介质从第一集流管11进入，通过第一连通件20在相邻两个换热器芯体10之间流通；第二连通件30的两端分别连接相邻两个换热器芯体10的第二集流管12，流体介质通过第二连通件30在相邻两个第二集流管12之间流通。
可以理解的是，通过设置第一连通件20将相邻两个第一集流管11相连接，设置第二连通件30将相邻两个第二集流管12相连接，从而将相邻两个换热器芯体10连接形成组合式换热器100，无需对第一集流管11或第二集流管12进行折弯，有效地避免因第一集流管11或第二集流管12折弯不当造成 的变形、表面损伤的情况，以提高换热性能，且便于组合式换热器100的拆卸及组装。
具体地，第一集流管11的直径小于第二集流管12的直径；当作为蒸发器使用时，气液两相的流体介质进入第一集流管11内，经过蒸发后变成气态导致体积增大，从而进入第二集流管12内，此时第二集流管12的直径大于第一集流管11的直径能够有足够的空间使气态流体介质流通。
进一步地，如图2所示，第一连通件20包括两个第一直管22以及设于两个第一直管22之间的第一弯管21，第一直管22的端部与第一集流管11连通并焊接于第一集流管11上；通过对第一连通件20的组装与拆卸，便于换热器芯体10之间的自由组装布置，不会产生因第一集流管11折弯不当而造成泄露的问题。
如图1所示，换热器芯体10还包括扁管13，扁管13用于冷凝水的排出。
具体地，扁管13呈竖直布置，且扁管13的两端分别与第一集流管11及第二集流管12相连，由于重力作用，当水达到一定量的程度后，扁管13能够将冷凝水排走，利于冷凝水的排水；且扁管13的数量为多根，多根扁管13分别沿第一集流管11和第二集流管12的轴向彼此间隔布置。
在其他实施例中，组合式换热器100还包括分液装置(图未示)，分液装置设于第一集流管11中，第一连通件20两端分别与相邻两个第一集流管11中的分液装置连通，便于分液装置的拆卸及更换。
具体地，第一弯管21的两端分别具有扩口段23，能够保证第一直管22伸入第一弯管21内，便于第一直管22与第一弯管21的连接，两个第一直管22分别伸入对应的扩口段23内，并与第一弯管21连接。
如图1所示，第二连通件30包括两个第二直管32以及设于两个第二直 管32之间的第二弯管31，第二直管32的端部与第二集流管12连通并焊接于第二集流管12上，通过对第二连通件30的组装与拆卸，便于换热器芯体10之间的自由组装布置，且不会产生因第二集流管12折弯不当而造成泄露的问题。
具体地，第二弯管31的直径大于第一弯管21的直径。当换热器芯体10作为蒸发器使用时，气液两相的流体介质从第一集流管11进入第一弯管21内，经过蒸发后变成气态流体介质导致体积增大，从而流入第二集流管12进入第二弯管31内，此时第二弯管31的直径大于第一弯管21的直径能够有足够的空间使气态流体介质在相邻两个第二集流管12内流通。
如图1所示，组合式换热器100还包括连接件40，连接件40固定连接于相邻两个换热器芯体10的边板14上，起到了加强固定连接和挡风的作用。
在本申请中，连接件40为板状的金属件，通过焊接连接；当然，在其他实施例中，连接件40也可以是其他形状的金属件，如管状的金属件，通过卡接相连接。
进一步地，组合式换热器100还包括进口管50以及出口管60，进口管50与第一集流管11连通，出口管60与第二集流管12连通，便于流体介质的流通；作为蒸发器使用时，气液两相的流体介质经进口管50进入第一集流管11内，经过蒸发后变成气态，从而经第二集流管12流入出口管60。
具体地，进口管50与出口管60设置于同一个换热器芯体10上，或者进口管50与出口管60分别设置于不同的换热器芯体10上。
本申请提供的组合式换热器100，通过设置第一连通件20将相邻两个第一集流管11相连接，设置第二连通件30将相邻两个第二集流管12相连接，从而将相邻两个换热器芯体10连接形成组合式换热器100，无需对第一集流 管11或第二集流管12进行折弯，有效地避免因第一集流管11或第二集流管12折弯不当造成的变形、表面损伤的情况，以提高换热性能，且便于组合式换热器100的拆卸及组装。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式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。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
