目前，盘管换热器的分集水方案主要是：主系统的进水管连接分水接头，水从进水管进入分水接头；分水接头连接各分路进水支管，水通过分水接头分流至各进水支管；各进水支管连接到各支路的换热管中，水从各支管流入对应各流路的换热管中；各出水支管与各个流路的换热管连通，并与集水接头连接，水从换热管流出经各出水支管后集流到集水接头；集水接头与主系统出水管连接，水经集水接头流入主系统的出水管，回到主系统中。分集水构件的总零部件数量较多，结构较为复杂，装配效率较低。
为了缓解上述问题，如图1至图28所示，根据本申请的实施方式，提出了一种盘管换热器10，包括分集水组件100和换热组件200。分集水组件100内具有进水通道101以及出水通道102，且出水通道102与进水通道101之间相互隔离布置。换热组件200包括多条盘管210，每一条盘管210具备有进水端211以及出水端212，进水端211上的管口为进水口，出水端212上管口为出水口，分集水组件100与各条盘管210中的进水端211均连接，各个盘管210中的进水口均与分集水组件100的进水通道101连通，分集水组件100还与各条盘管210中的出水端212均连接，且各个盘管210中的出水口均与分集水组件100的出水通道102连通。
盘管换热器10通常与风机20搭配使用，风机20可以设置于盘管换热器10的一侧，风机20用于驱动气流流动，以使气流流经盘管换热器10，气流流经盘管换热器10时，气流与盘管换热器10内的水进行热交换。
换热组件200是用于进行热交换的主要部件，具体的，换热组件200是将流动在换热组件200内的水与换热组件200外的空气等介质进行热交换。多条盘管210指的是两条及两条以上的盘管210，每一条盘管210可以理解为从进水通道101流向出水通道102的一条管路组，每条盘管210的进水口可以是一个、两个或两个以上，每套盘管210的出水口也可以是一个、两个或两个以上，例如在一些实施例中，至少有一条盘管210的进水管为一条，出水管为多条，多条出水管均与进水管连接并连通。其中，每条盘管210至少具有一次弯折回流，简单而言，每条盘管210至少包括两段换热段，两段换热段的水流方向大致相反，更为具体的，可以理解为，每条盘管210至少包括一根长U型管。
分集水组件100可以包括壳体110，进水通道101和出水通道102均设置在壳体110内，且进水通道101和出水通道102为相互独立的通道。分集水组件100上可以设置有进水接头140和出水接头150，其中，进水接头140可以与分集水组件100形成进水通道101的部位连接，并与进水通道101连通，换热供水系统的出水口与进水接头140连接，并通过进水接头140向进水通道101供水；出水接头150可以与分集水组件100形成出水通道102的部位连接，并与出水通道102连通，换热供水系统的进水口与出水接头150连接，换热组件200内的水流通过出水接头150回流至换热供水系统。换热供水系统用于对水流进行加热或降温，在换热组件200用于为环境提供制热时，换热供水系统对水流进行加热，以向换热组件200提供热水，换热供水系统具体可以设置加热装置，例如燃气加热装置，电热管等，对水流进行加热；在换热组件200用于为环境提供制冷时，换热供水系统可以对水流进行降温，换热供水系统具体可以设置冷却装置，例如蒸发器等，对水流进行降温。
分集水组件100对应进水通道101可以设置有多个第一连通口115，多个第一连通口115与多条盘管210中的进水端211连接，具体而言，一个第一连通口115可以连接一个盘管210中的进水端211，具体的，盘管210中的进水端211可以与第一连通口115插接密封连接，例如，可以是盘管210中的进水端211插入第一连通口115内，并与第一连通口115密封连接。分集水组件100对应出水通道102可以设置有多个第二连通口116，多个第二连通口116与多条盘管210中的出水端212连接，具体而言，一个第二连通口116连接一个盘管210的出水端212，具体的，盘管210中的出水端212可以与第二连通口116插接密封连接，例如，可以是盘管210中的出水端212插入第二连通口116内，并与第二连通口116密封连接。用于换热的水流入进水通道101后，通过进水通道101分流至各个盘管210的进水端211的进水口，然后分别流经各个盘管210后，经各个盘管210的出水端212的出水口集流至出水通道102，并经出水通道102流出。其中，水流在流经各个盘管210时与空气进行热交换。
本实施例盘管换热器10，换热组件200的多条盘管210的进水口均通过进水通道101连通，多条盘管210的出水口均通过出水通道102连通，且进水通道101与出水通道102集成于分集水组件100上，换热器的结构简单，零件较少，装配方便，提高了盘管换热器10的加工、装配效率，降低了生产成本。
在一些技术中，盘管换热器通过分水接头连接多根分支管，多根分支管与换热管的进水口连接，同时集水接头连接多根分支管，换热管通过该分支管与集水接头连接的方式，以实现多条换热管内的水的集流和分流。其中，分水接头、集水接头、分支管为独立的零件，这样，分水接头与其连接的分支管之间、出水结构与其连接的分支管之间、这样分支管与换热管的进口之间以及分支管与换热管的出水口之间均需要组装，零件较多，且结构组装过程较为繁琐，费时费力，对于盘管换热器的制备成本影响较大；而且进水组件(分水接头与对应的分支管形成进水组件)与出水组件(集水接头与对应的分支管形成出水组件)分开焊接和装配，容易变形，为此需要增加额外的安装板予以固定；分水接头和集水接头通常为圆盘形，其小于多根换热管的进口和出口的布置范围，所以分支管多为弯折的长支管，占据的空间较大。同时，由于零件分散且较多，导致分集水组件占用的无效空间较大，零件杂乱，美观性差，并不利于盘管换热器的集成化设计。流入换热管的水流从集水接头流出后需要流经分支管才能进入换热管，且流出换热管的水流从换热管流出后也需要经过分支管后才能回流，换热组件的管程长、水阻力大。
而本实施例盘管换热器10，盘管210的进口端与分集水组件100直接连接，盘管210中的出口端也与分集水组件100直接连接，不需要设置分支管，结构简单，组装方便，水流流程较短，水阻力降低，有利于提高换热效率；同时，分集水组件100集成有进水通道101和出水通道102，不需要独立设置零散的分水接头和集水接头，零件减少，且构件不易变形，有利于使分集水组件100有序布置，降低零件杂乱程度，可以降低零件占用的无效空间，提高盘管换热器10的集成化程度和美观性。
在一些实施例中，换热组件200的盘管210外还可以设置有翅片240，也就是说，盘管换热器10可以是翅片管式换热器，盘管210通过翅片240与气流进行热交换，可以提高换热器的换热效率。其中，翅片240可以通过胀接、焊接等方式连接在盘管210上，在一些实现方式中，翅片240上设置有安装孔，盘管210穿设于安装孔内，以使翅片240套设连接于盘管210上。翅片240的数量可以是多个，多个翅片240可以间隔设置，例如，多个翅片240可以沿第一方向X间隔排列在盘管210上。
可选的，换热组件200还可以设置有外壳230，多条盘管210均设置在外壳230内，外壳230的其中一侧面(为了便于描述定义为第一侧面)设置有进风口，外壳230与进风口相对的侧面(为了便于描述定义为第二侧面)设置有出风口231。分集水组件100可以设置于外壳230的端面上，其中，外壳230的端面与外壳230的第一侧面垂直。
需要说明的是，第一侧面可以局部镂空形成进风口，第一侧面也可以全部镂空即外壳230在第一侧面不设置侧壁，以形成进风口；第二侧面可以局部镂空形成出风口231，第二侧面也可以全部镂空即外壳230在第二侧面不设置侧壁，以形成出风口231。其中，在图28中，第二侧面全部镂空而形成出风口231，为了简化附图，图28仅在第二侧面的局部位置显示了盘管换热器10的实际结构，并未示意出盘管换热器的内部全部结构。
其中，外壳230可以为大致长方体形结构。进风口和出风口231也可以设置于外壳230的两相邻的侧面上。外壳230用于与分集水组件100连接的端面可以镂空设置，即外壳230的该端面可以为开口结构，为了便于描述，定义为第二开口，分集水组件100与外壳230的侧面连接，以固定在外壳230的端面的第二开口处，也就是说，外壳230与分集水组件100可以固定连接，且分集水组件100作为外壳230的端壁使用；外壳230的端面也可以为实体结构。
多条盘管210的流程可以设置为相同，也可以设置为不同。盘管210可以包括至少两段换热段，多段换热段依次串联连通设置，每段换热段可以是一条换热管也可以有多条换热管，任意一段换热段有多条换热管时，多条换热管并联设置。也就是说，沿水流方向，在不同位置时，换热管的数量可以不同，例如，可以是一根进水管的出口连接多根出水管，也可以是多根进水管的出口连接同一进水管，也可以是一根进水管与一根出水管连通等。多段换热段的所有换热管可以长度大致相同，且所有换热管的两端分别大致对齐设置，多段换热段形成依次弯曲回折的盘管210结构。
在一种实现方式中，如图1和图2所示，多段换热段的任意一根换热管均沿第一方向X布置，所有换热管沿第一方向X的第一端可以大致对齐，所有换热管沿第一方向X的第二端大致对齐，多根换热管沿第二方向Y和第三方向Z间隔设置。分集水组件100设置于换热管沿第一方向X的第一端，多条换热管中，第一段换热段的换热管的第一端均与分集水组件100的进水通道101连通，如图3至图10所示，进入进水通道101的水流沿着路径B从进水通道101流向多个第一段换热段的换热管的第一端，然后经多个第一段换热段的换热管沿第一方向X流动至第二端，并从多个第一段换热段的换热管的第二端进入第二段换热段的换热管，然后从第二段换热段的换热管沿第一方向X的反方向回流至第二段换热段的换热管的第一端，形成一次回流。在一些实施例中，如图7所示，换热组件200的流程较短，第二段换热段的第一端与出水通道102连通，水流沿着路径D经第二段换热段的换热管的第一端回流至出水通道102,也就是说，水流流经一根长U型管，该过程也可参照图8的水流流动路径A4理解。在另一些实施例中，如图9和图10所示，换热组件200的流程较长，第二段换热段的第一端可以再与第三段换热段的第一端连通，水流沿着图9的路径C经第二段换热段的换热管的第一端流入第三段换热段的换热管的第一端，然后从第三段换热段的换热管沿第一方向X流至第三段换热段的换热管的第二端，再经第四换热段回流至第一端，形成第二次回流，第四换热段的第一端可以与出水通道102连通，水流沿着图9的路径D经第四段换热段的换热管的第一端回流至出水通道102；也就是说，水流流经两根长U型管(依次流经第一长U型管201和第二长U型管202)，该过程也可参照图11的水流流动路径A5理解。每个盘管210或部分盘管210也可以包括6个或6个以上的偶数换热段(即三根长U型管或更多根长U型管)，以形成更多次的回流，具体的布置方式，可以参照第一段与第四段的循环布置方式，以每条盘管210设置三根长U型管为例，如图3所示，从第一长U型管201流出的水流沿着路径C1从第一长U型管201流出并流经第一回流通道1211后流向第二长U型管202，从第二长U型管202流出的水流沿着路径C2从第二长U型管202流出并流经第二回流通道1212后流向第三长U型管203，从第二长U型管202流出的水流沿着图3所示的路径D回流至出水通道102,该水流过程也可参照图4所示的水流流动路径A2。
其中，一次回流也即是一个流程，具体一次回流指的是水流从第一端流至第二端，并从第二端又回流至第一端的一次回折流动路径，两次回流指的是水流需要经过上述两次回折流动路径，同理，三次及更多次回流均是水流需要经过对应次数的回折流动路径。第一方向X可以是换热组件的长度方向，第二方向Y可以是换热组件的宽度方向，第三方向Z可以是换热组件的高度方向，第一方向X、第二方向Y和第三方向Z可以两两相互垂直设置。
沿水流流动方向，每条盘管210在第二端连通的换热管之间可以通过接头连通，也就是说，在第二端中，上游的换热管的出口与下游换热管的进口之间可以通过接头连接，在上游换热管和下游换热管均为一根换热管时，两者可通过U型接头连接，接头与两根换热管可以是一体结构，例如焊接为一体的长U型管结构，或者注塑为一体的长U型管结构等，换热管在第二端连接为一体，相当于一个回流采用了一体结构的一根长U型管，在形成两次或两次以上回流时，相当于两根或两根以上的长U管中，上游的长U型管的出口与下游的长U型管的进口在第一端连接并连通，每根长U形管的U型连接部位于第二端。
需要说明的是，每条盘管210在第二端的连通，也可以通过设置一体结构的第二回水结构实现。第二回水结构设置于换热组件200的沿第一方向X的第二端，第二回水结构可以设置有回水腔，上游换热管的第二端和沿水流流动方向相邻的下游换热管的第二端均与回水腔连通。多条盘管210可以同用一个第二回水结构，具体的可以是第二回水结构上设置多个回水腔，同一条盘管210中相邻的两段换热管的第二端可通过一个回水腔连通；在一个回流中，多条盘管210在第二端的压力相同时，在相同次的回流中，多条盘管210的相邻换热管的第二端可以同用一个回水腔，例如，所有盘管210均包括一次回流，第二回水结构可以设置有一个回水腔，所有盘管210的第一段换热段的第二端均通过该回水腔与第二段换热段的第二端连通；再例如，所有盘管210均包括两次回流，第二回水结构可以设置有两个间隔且独立的回水腔，所有盘管210的第一段换热段的第二端均通过其中一个回水腔与第二段换热段的第二端连通；所有盘管210的第三段换热段的第二端均通过另一个回水腔与第四段换热段的第二端连通。
需要说明的是，在本实施例中，除非特殊指出之外，主要以每条盘管210通过一条长U形管形成或多条长U形管顺次连通为例进行说明，长U形管的进口端和出口端均位于换热组件200的第一端为例进行说明，其中，盘管210的回流次数与U型管的数量一致。例如，在如图7和图8所示，在具有一次回流时，每条盘管210只需要一根U型管，一根U型管并列的两个侧边形成了盘管210的第一段换热段和第二段换热段；再例如，在图9和图10中，在具有两次回流时，每条盘管210包括两根U型管，第一长U型管201的出口与第二长U型管202的进口在第一端连接并连通，第一长U型管201并列的两个侧边形成了盘管210的第一段换热段和第二段换热段，第二长U型管202并列的两个侧边形成了盘管210的第三段换热段和第四段换热段。再例如，如图3至图4所示，在具有两次回流时，每条盘管210包括三根U型管，第一长U型管201的出口与第二长U型管202的进口在第一端连接并连通，第二长U型管202的出口与第三长U型管203的进口在第一端连接并连通，第一长U型管201并列的两个侧边形成了盘管210的第一段换热段和第二段换热段，第二长U型管202并列的两个侧边形成了盘管210的第三段换热段和第四段换热段，第三长U型管203并列的两个侧边形成了盘管210的第五段换热段和第六段换热段。
在盘管210具有两次回流或两次以上回流时，沿水流流动方向，上游换热段的第一端与下游换热段的第一端之间可以通过额外设置接头连通，例如半圆形或U型的接头等，在一些实施例中，也可以在分集水组件100上设置第一回水结构120，以使上游换热段的第一端与下游换热段的第一端之间通过第一回水结构120连通。
需要说明的是，盘管210中相关的上游和下游是以水流流动方向为参照进行的定义，其中，沿水流流动方向，靠近进口的为上游，靠近出口的为下游，即水流从上游向下游流动。
在一个实施例中，分集水组件100内还设置有第一回水结构120，多条盘管210中至少有一条盘管210为第一盘管220，每条第一盘管220包括第一换热管221和第二换热管222，第一换热管221与第二换热管222并列布置，第一换热管221的出口以及第二换热管222的进口均朝向分集水组件100的第一端设置，在同一条第一盘管220中，第一换热管221的出口与第二换热管222的进口通过第一回水结构120连通，以使第一换热管221与第二换热管222串联连通。
其中，进水通道101可以设置于第一回水结构120的一侧，出水通道102可以设置于第一回水结构120的另一侧。也就是说，第一回水结构120设置在进水通道101以及出水通道102之间，并将进水通道101与出水通道102相互隔离。具体的，在一个实现方式中，分集水组件100形成有容置腔1117，第一回水结构120设置于容置腔1117，且第一回水结构120将容置腔1117分隔为出水通道102和进水通道101。
可以理解的是，对于一条第一盘管220而言，第一盘管220的进水口可以与该第一盘管220中的第一换热管221的进口连通，第一换热管221的出口可以与该条第一盘管220的第二换热管222的进口通过第一回水结构120连通，第二换热管222的出口与该条第一盘管220的第一盘管220的出水口连通。
其中，第一盘管220实际上也即是包括两次回流或两次回流以上的盘管210。所有盘管210中可以是其中一部分盘管210设置为第一盘管220，另一部分设置为只有一次回流的盘管210，也可以是全部盘管210均设置为第一盘管220。
第一换热管221以及第二换热管222可理解为在第一方向X的第一端相互连接并连通的两换热管。例如，如图9和图10所示，第一盘管220具有两次回流时，第二段换热段中的换热管(即第一长U型管201的出口段)与第三段换热段中的换热管(即第二长U型管202的进口段)可以作为第一换热管221和第二换热管222，换言之，第一段换热段和第二段换热段为第二端连接为一体的长U型管，第三段换热段与第四段换热段为第二端连接为一体的U型管的情况下，上游长U型管的出口与下游U型管的进口在第一端通过第一回水结构120连通。再例如，如图3和图4所示，第一盘管220具有三次回流时，第二段换热段中的换热管(即第一长U型管201的出口段)与第三段换热段(即第二长U型管202的进口段)中的换热管成第一换热管221和第二换热管222，第四段换热段中的换热管(第二长U型管202的出口段)与第五段换热段(第三长U型管203的进口段)中的换热管成第一换热管221和第二换热管222，换言之，第一段换热段和第二段换热段为第二端连接为一体的长U型管，第三段换热段与第四段换热段为第二端连接为一体的U型管的情况下，第五段换热段与第六段换热段为第二端连接为一体的U型管的情况下，三根长U型管中，上游长U型管的出口与下游U型管的进口在第一端通过第一回水结构120连通。
在实际布置时，可以将换热组件200中，在第一端需要相互连通的所有换热管之间均通过同一第一回水结构120连通。例如，在有多组第一换热管221和第二换热管222的情况下，第一回水结构120上可以对应设置多个间隔设置的回流通道121，以使多组第一换热管221和第二换热管222分别通过不同的回流通道121连通，在多组第一换热管221和第二换热管222有两组或两组压差相同时，也可以在第一回水结构120上设置一个较大的回流通道121，通过一个回流通道121将多组第一换热管221和第二换热管222进行连通。
在一些实施例中，第一回水结构120设置有回流通道121，多条盘管210中至少有两条盘管210为第一盘管220，至少有两个第一换热管221与对应的第二换热管222通过同一回流通道121连通。
其中，如图9和图10所示，通过第一回流通道1211连通的多组第一换热管221与第二换热管222，多个第一换热管221为等压通道，多个第二换热管222为等压通道。多条第一盘管220中同一回流中的第一换热管221与第二换热管222可以通过同一回流通道121连通，在该实施例中，回流通道121的数量可以等于第一盘管220的回流次数减一。例如，如图9和图10所示，所有第一盘管220均为两次回流时，第一回水结构120可以设置有一个回流通道121，在所有第一盘管220中：第二段换热段中的换热管与第三段换热段中的换热管通过该回流通道121连通。再例如，所有第一盘管220均为三次回流时，第一回水结构120可以设置有两个相互独立的回流通道121，在所有第一盘管220中：第二段换热段中的换热管与第三段换热段中的换热管通过其中一个回流通道121连通，第四段换热段中的换热管与第五段换热段中的换热管通过另一个回流通道121连通。
在另一些实施例中，如图3、图4并结合图5和图6所示，多条盘管210中至少有两条盘管210为第一盘管220，第一回水结构120设置有多个回流通道121，多个第一换热管221与对应的第二换热管222之间一一对应设置有回流通道121。也就是说，每组第一换热管221与其在第一端连通的第二换热管222均对应有一个回流通道121，且该回流通道121仅与一组第一换热管221与其在第一端连通的第二换热管222。
在一个具体实施例中，参照图5和图6所示，多条盘管210为具有两次回流的第一盘管220，这样，每个第一盘管220均包括一组第一换热管221与第二换热管222，第一回水结构120对应每一条第一盘管220分别设置有一个回流通道121。其中，图5和图6中，不仅包括具有两次回流的第一盘管，而且至少有一条盘管210为一条U型管，既该盘管210只具有一次回流，该盘管210内的水流沿着图5所示的路径B和D流动，该过程也可参照图6的水流流动路径A3理解。
在另一个具体实施例中，如图3和图4所示，多条盘管210为具有三次回流的第一盘管220，这样，每个第一盘管220均包括两组第一换热管221与第二换热管222，第一回水结构120对应每一条第一盘管220分别设置有两个回流通道121。
在具有多个回流通道121的方案中，如图3和图5所示，第一回水结构120包括间隔设置的多个凸块122，相邻凸块122之间通过隔板123连接，凸块122和隔板123均连接于壳体110的内壁面，每个凸块122上设置有回流通道121。其中，凸块122与回流通道121可以一一对应设置，也可以根据需要在一个凸块122上设置多个回流通道121。在凸块122数量较多时，为了提高空间利用率，可以将部分凸块122的长度方向相对壳本体111(分集水组件100的壳体110的一部分)的顶板1112倾斜设置，且沿壳本体111的高度方向(可参照第三方向Z)，相邻的两个凸块122的倾斜方向可以相反，这样相邻的凸块122交错布置，使得在较小的空间内可以设置多个凸块122，从而可以实现较多数量的回流通道121的设置。隔板123与凸块122之间密封设置，具体的，隔板123与凸块122可以是一体结构，隔板123、凸块122与壳本体111也可以为一体结构。
需要说明的是，在一条第一盘管220中具有三次回流及以上时，可以对应每次回流的第一端的第一换热管221与第二换热管222均设置回流通道121。以一条第一盘管220中具有三次回流为例，第一回水结构120对应该条第一盘管220设置两个回流通道121，第二段换热段中的换热管与第三段换热段中的换热管通过其中一个回流通道121连通，第四段换热段中的换热管与第五段换热段中的换热管通过另一个回流通道121连通。
本实施例的第一回水结构120可以是一体结构，具体的，第一回水结构120可以是注塑为一体的结构，也可以是焊接为一体的结构等。
在一些实施例中，分集水组件100包括壳体110，壳体110内形成容置腔1117，容置腔1117内分隔形成进水通道101和出水通道102。如图7和图8所示，在不具有第一回水结构120的情况下，可以直接在容置腔1117内设置隔离板124，通过隔离板124将容置腔1117分为进水通道101和出水通道102。在具有第一回水结构120的情况下，可以是第一回水结构120连接在壳体110的内壁面上，将容置腔1117分隔为进水通道101和出水通道102。壳体110连接在换热组件200的一端，也即是外壳230的一端。
可选的，壳体110朝向外壳230的侧壁对应进水通道101的位置设置有多个连通口118，连通口118连通容置腔1117，盘管210与连通口118密封连接，并通过连通口118与容置腔1117连通。
其中，部分数量的连通口118可以对应进水通道101设置，这些连通口118定义为第一连通口115，所有第一连通口115之间间隔设置，所有盘管210中的进水端211可与第一连通口115密封连接，并通过第一连通口115与进水通道101连通。剩余数量的连通口118中的至少部分连通口118可以对应出水通道102设置，这些连通口118定义为第二连通口116，所有第二连通口116之间间隔设置，所有盘管210中的出水端212可与第二连通口116密封连接，并通过第二连通口116与出水通道102连通。
具体的，每个第一连通口115可以与一条盘管210的进水端211对应密封连接，并与进水通道101连通，也就是说，所有盘管210中的进水端211分别一一对应连接于所有第一连通口115，且进水端211的周向侧壁与第一连通口115的周壁密封连接，避免水从进水端211与第一连通口115之间泄露，同时进水端211与进水通道101连通。壳体110朝向外壳230的侧壁对应出水通道102的位置设置有多个第二连通口116，所有第二连通口116之间间隔设置，每个第二连通口116与一条盘管210的出水端212对应密封连接，并与出水通道102连通。也就是说，所有盘管210中的出水端212分别一一对应连接于所有第二连通口116，且出水端212的周向侧壁与第二连通口116的周壁密封连接，避免水从出水端212与第二连通口116之间泄露，同时出水端212与出水通道102连通。
本实施例的壳体110可以大致为矩形或椭圆形，其与换热组件200的端部匹配。
在一些实现方式中，壳体110朝向换热组件200的侧壁可以局部镂空，形成第一连通口115和第二连通口116。可选的，盘管210的进水端211可以插设在对应的第一连通口115内，并与第一连通口115的周向内壁密封连接。可选的，盘管210的出水端212可以插设在对应的第二连通口116内，并与第二连通口116的周向内壁密封连接。
壳体110可以是一体成型的结构，也可以是连接为一体的结构，也可以是可拆卸密封连接结构。在一些实施例中，壳体110包括壳本体111和密封板112，壳本体111的一侧设置有第一开口1111，壳本体111上设置有相互隔离的第一凹槽113和第二凹槽114，第一凹槽113的槽口和第二凹槽114的槽口均与第一开口1111的朝向一致，密封板112密封于第一开口1111，并与第一凹槽113与围合形成进水通道101，与第二凹槽114围合形成出水通道102。其中，密封板112位于壳本体111朝向换热组件200的一侧，即朝向外壳230的一侧，也就是说，密封板112是壳体110朝向换热组件200的侧壁。
密封板112可以与换热组件200的外壳230固定连接。具体的，在一种实现方式中，外壳230的一端可以为开口结构，即外壳230的一端具有第二开口，密封板112覆盖于外壳230的第二开口处，并与外壳230固定连接，也就是说，密封板112可以作为壳本体111的边板(即端板)使用，密封板112可以理解为壳本体111的端板。在另一种实现方式中，壳体110的端面可以为实体结构，密封板112连接在端面上。其中，密封板112可以与换热组件200的外壳230可拆卸连接，例如通过螺钉、卡接等方式连接，也可以非可拆卸连接。如图1、图2、图3所示，可选的，密封板112沿宽度方向(可参照第二方向Y理解)的两侧可以设置有翻边1121，外壳230定位安装在两个翻边1121之间。翻边1121除了定位外壳230之外，还可以与其他结构连接。
需要说明的是，如图27所示，外壳230与密封板112连接的一端也可自带端板232的结构，也就是说，外壳230与密封板112连接的一端设置有端板232，密封板112与端板232固定连接。由于上分集水组件100承担重要的水流分配功能，其密封性和耐压性的要求较高，外壳230引入额外端板232零件，整机在运输、搬运、安装等过程中出现的晃动、跌落、撞击等的受力可以由端板232承担，不会传递到分集水组件100上，可以保持分集水组件100的密封效果和承压能力。需要说明的是，盘管210穿过外壳230额外设置的端板232，具体的该端板232与盘管210可以胀接连接，盘管210与壳体110自带的端板232为非密封结构，且端板232与整机其他结构件相连接，起到结构固定的作用。外壳230自带的端板232与外壳230可以为一体结构，当然也可以为分体组装结构。
其中，密封板112可以是一体成型的板结构，壳本体111也可以是一体成型的结构。壳本体111与密封板112之间可以通过焊接等方式连接为一体，也可以通过螺钉等方式固定连接，需要说明的是，无论何种连接方式，密封板112与壳本体111之间应当形成密封，以使进水通道101和出水通道102可以相互独立，且不会漏水，具体的可以通过焊接密封、胀接密封、胶水密封、胶垫(密封圈)密封等手段实现。密封板112上的第一连通口115与盘管210的进水端211之间可以通过焊接连接、密封圈密封连接、胶水密封连接、胀接密封连接等，密封板112上的第二连通口116与盘管210的出水端212之间也可以通过焊接连接、密封圈密封连接、胶水密封连接、胀接密封连接等。
在一些实施例中，分集水组件100还包括密封垫130，密封垫130密封设置于密封板112与壳本体111之间。
在一些实施例中，第一回水结构120与壳本体111的内壁面连接，且两者为一体结构，具体的可以是第一回水结构120与壳本体111注塑为一体结构。其中，第一回水结构120和壳本体111可以采用的相同的材质，例如，可以第一回水结构120以及壳本体111可以是金属材质，此时，第一回水结构120以及壳本体111可以焊接或粉末合金烧结或沙铸或锻造或机加工等一体成型；第一回水结构120以及壳本体111也可以是陶瓷材质或玻璃材质，此时，第一回水结构120以及壳本体111可以通过烧结等方式形成一体结构；第一回水结构120以及壳本体111也可以是塑料材质，此时，第一回水结构120以及壳本体111可以通过注塑、烧结、模压等方式一体成型。
在一些其他实施例中，如图23和图24所示，壳本体111可以包括周向框1113和顶板1112，顶板1112连接在周向框1113背离密封板112的一端，周向框1113与顶板1112密封连接，且两者可以是分体组装结构，第一回水结构120可以分体组装或一体成型在顶板1112的内壁面上。可以理解的是，盘管换热器10根据使用环境和要求不同，换热组件200的结构不同，例如，可以是不带第一回水结构120的分集水组件100，也可以是带有第一回水结构120的分集水组件100，在带有第一回水结构120的分集水组件100中，第一回水结构120也可以不同，通过将壳本体111设置为周向框1113和顶板1112分离组装的结构，周向框1113可以作为标准件使用，可以通用于不同的第一回水结构120中，使得周向框1113可以批量自动化大规模生产，生产效率高、成本较低。
在另外一些实施例中，如图25和图26所示，壳本体111的周向框1113和顶板1112为一体结构，第一回水结构120分体组装至顶板1112上。这样，壳本体111整体可以作为通用标准件，针对于不同的盘管换热器10，只需要向壳本体111组装不同的第一回水结构120即可，使得壳本体111可以作为标准件使用，使得壳本体111可以批量自动化大规模生产，生产效率高、成本较低。
本实施例中，盘管210与密封板112的密封连接可以有多种形式，下面具体介绍几种密封方案。
在一些实现方式中，如图13和图14所示，密封板112可以是金属材料，换热管也是金属材质，盘管210的进水端211可以与密封板112的第一连通口115处焊接连接，盘管210的出水端212可以与密封板112的第二连通口116处焊接密封连接，具体可以是，密封板112对应第一连通口115和第二连通口116的位置形成凸起环，凸起环的内壁面为密封连接面1122，密封连接面1122与盘管210通过焊料1123密封连接，具体的焊接方式可以是火焰焊、过炉焊或高频焊接等。
在一些实现方式中，如图15所示，密封板112与盘管210的进口端和出口端均过盈配合，且密封板112的第一连通口115的内径(即第一连通口115与换热管的接触面对应的直径)内径小于等于胀管后的盘管210的进口端，密封板112的第二连通口116的内径(即第二连通口116与换热管的接触面对应的直径)小于等于胀管后的盘管210的出口端外径，形成过盈连接，起到密封作用；在该种胀接方案中，密封板112的厚度可以大于等于5mm，第一连通口115的内壁面和第二连接口的内壁面可以设置密封槽，密封板112的材质可以是金属或陶瓷或玻璃或塑料或橡胶或硅胶，或上述材料的复合材料。盘管210的材质一般为金属管，以提高换热效率。具体的，密封板112对应第一连通口115和第二连通口116的位置形成凸起环，凸起环的内壁面为密封连接面1122，密封连接面1122与盘管210过盈配合。
在一些实现方式中，如图13所示，密封板112的第一连通口115内侧与盘管210的进水端211外周壁之间还可以涂覆胶水，第二连通口116的内侧与盘管210的出水端212外周壁之间也可以涂胶水，盘管210可以焊接或胀接的方式连接在密封板112上，胶水附着在盘管210的外壁和密封板112的连通口的内侧之间，起到密封作用。
在一些实现方式中，如图16所示，密封板112的第一连通口115内侧与盘管210的进水端211的外周壁之间以及第二连通口116的内侧与盘管210的出水端212外周壁之间放置密封圈1124，如O型圈，也就是说，密封板112与盘管210的管外壁接触面内侧放置密封圈1124，在盘管210胀管后，密封圈1124被挤压至盘管210的外壁与密封板112的连通口的内壁之间，起到密封作用。密封圈1124可以是橡胶或硅胶材质。
在一些实现方式中，如图17、图18和图19所示，分集水组件100还包括密封垫130，密封垫130密封设置于密封板112与壳本体111之间，密封垫130覆盖于第一开口1111，密封垫130设置有多个贯通口134，贯通口134与连通口118一一对应并同轴设置，盘管210穿过连通口118并与贯通口134密封连接。
其中，贯通口134至少包括多个第一贯通口131和多个第二贯通口132。具体而言，密封垫130与进水通道101的位置对应设置有多个第一贯通口131，密封垫130与出水通道102的位置对应设置有多个第二贯通口132，多个第一贯通口131与多个第一连通口115一一对应并同轴设置，多条盘管210的进水端211一一对应穿过第一连通口115，并与第一贯通口131密封连接，多个第二贯通口132与多个第二连通口116一一对应并同轴设置，多条盘管210的出水端212均一一对应穿过第二连通口116，并与第二连通口116密封连接。
其中，密封垫130为橡胶、硅胶等材质，在组装时，密封板112的第一连通口115与盘管210的进水端211的接触面之间，以及密封板112的第二连通口116与盘管210的出水端212的接触面之间存在一定间隙，密封垫130套在盘管210的进水端211和出水端212，在壳本体111与密封板112装配时，壳本体111与密封板112之间的紧固力挤压两者之间的密封垫130，使得部分密封垫130材料挤压至盘管210的外壁与密封板112的第一连通口115和第二连通口116之间的间隙之间，起到密封作用，同时盘管210的进口端与密封垫130的第一贯通口131可以过盈配合以起到密封作用，盘管210的出口端与密封垫130的第二贯通口132可以过盈配合以起到密封作用。本实施方式中，采用一个密封垫130可以使得多根盘管210的进口端和出口端的密封设置，操作方便，组装方便，且密封性较好。
需要说明的是，密封垫130的周向边缘还可以对壳本体111与密封板112的连接气道密封作用，具体的密封垫130的周向边缘的端面沿着周向可以设置一圈或多圈密封槽，在有多圈密封槽时，每圈密封槽均颜值密封垫130的周向边缘环绕一圈，多圈密封槽沿着密封垫130的厚度方向间隔布置，其中，多圈密封槽可以起到多圈，可以起到多层密封作用。采用密封垫130的方案中，盘管210也可以采用胀接的方式与密封垫130、密封板112连接。
可选地，在密封垫130的方案中，密封垫130的第一贯通口131和第二贯通口132的内壁可以设置有周向密封槽，和/或，第一连通口115和第二连通口116的内壁也可以设置有周向密封槽，盘管210的外周壁可以设置有密封圈，密封圈可以对应设置在周向密封槽内，进一步提高密封效果。
其中，胀接指的是盘管210在内部气体或液体等压力的作用下向外膨胀后与密封板112连接的方式。盘管210进行胀接连接的一种实现方式可以是，先将盘管210以扁管的状态组装至第一连通口115和第二连通口116(和/或第一贯通口131和第二贯通口132等)，然后将盘管210的出口端临时密封，并通过盘管210的进口端充入气体等，使盘管210内的压力升高，盘管210通常为金属管，盘管210在压力作用下向外膨胀与密封板(和/或密封垫130)抵接，以实现连接。
需要说明的是，上述多种密封方案也可以组合使用，以使盘管210与密封板112之间形成较好的密封。还需要说明的是，在具有第一回水结构120时，密封板112上还设置有与回流通道121连通的第三连通口117，第三连通口117与对应的换热管(即长U型管)密封连接，在密封垫130的方案中，密封垫130也具有与第三连通口117对应的第三贯通口133，具体的密封方式可以参照盘管210的进水端211或出水端212与密封板112之间的密封连接方式，在此不再赘述。第一连通口115、第二连通口116可以是相同的结构，在有第一贯通口131的情况下，第一连通口115、第二连通口116和第一贯通口131可以均为相同的结构，例如，均为等径的圆形孔这样，在加工制备分集水组件100时，不需要区分第一连通口115、第二连通口116和第一贯通口131，加工方便性，效率较高。
在一些实施例中，进水接头140连接在壳体110远离换热组件200的侧壁上，具体可以是壳本体111与密封板112相对的侧壁对应进水通道101设置有进水通孔1114，进水接头140与进水通孔1114同轴设置并连通。其中，进水接头140可以是管状件，其内壁或者外壁可以设置有螺纹，使得进水接头140与换热供水系统的出水管可以螺纹连接，进水接头140可以至少部分位于壳本体111的外侧，并朝向壳本体111背离密封板112的一侧延伸，以便于进水接头140与换热供水系统的出水管连接。
可选的，出水接头150可以与进水接头140设置于壳体110的相同的侧壁上，例如，出水接头150也可以连接在壳体110远离换热组件200的侧壁上，具体可以是壳本体111与密封板112相对的侧壁对应进水通道101设置有出水通孔1115，出水接头150与出水通孔1115同轴设置并连通。其中，出水接头150可以至少部分位于壳本体111的外侧，并朝向壳本体111背离密封板112的一侧延伸。其中，出水接头150可以是管状件，其内壁或者外壁可以设置有螺纹，使得出水接头150与换热供水系统的进水管可以螺纹连接，出水接头150可以至少部分位于壳本体111的外侧，并朝向壳本体111背离密封板112的一侧延伸，以便于进水接头140与换热供水系统的进水管连接。
本实施例中，如图1、图2所示，进水接头140可以设置于出水接头150的下方，图中箭头A表示的是水流在分集水组件100内的流动方向。
可以理解的是，进水接头140和出水接头150设置于壳本体111上，连接组装方便；进水接头140与出水接头150设置于同一侧壁上，有利于提高盘管换热器10的构件布置合理性，降低进水接头140和出水接头150在不同方向占用的空间，也有利于换热供水系统从一个方向与分集水组件100进行连接。
需要说明的是，进水接头140和出水接头150也可以设置在壳本体111的不同的侧壁上。
在一些实施例中，可选的，如图1和图2所示，进水接头140和出水接头150与壳本体111可以是一体结构，可以是一体式加工而成一体结构，也可以是分体组装而成一体结构。在一些实施方式中，进水接头140和出水接头150以及壳本体111为相同材料，例如，进水接头140和出水接头150以及壳本体111均为金属材料，进水接头140和出水接头150以及壳本体111利用金属材料通过粉末合金烧结或沙铸或锻造或机加工等一体成型；再例如，进水接头140和出水接头150以及壳本体111为陶瓷、玻璃等材料，进水接头140和出水接头150以及壳本体111通过烧结等方式一体成型；再例如，进水接头140和出水接头150以及壳本体111为塑料等材质，进水接头140和出水接头150以及壳本体111塑料通过注塑或模压或3D打印(3D打印是快速成型技术的一种，又称增材制造，它是一种以数字模型文件为基础，运用粉末状金属或塑料等可粘合材料，通过逐层打印的方式来构造物体的技术)等一体成型。在另一些实现方式中，进水接头140和出水接头150以及壳本体111为不同材料，例如，进水接头140和出水接头150采用金属材料，壳本体111为非金属材料，进水接头140和出水接头150均嵌套在壳本体111的通孔中进行注塑、烧结、模压等方式一体成型。
需要说明的是，金属材料可以是不锈钢、铜等。进水接头140和出水接头150可以采用相同材质，也可以采用不同材质，进水接头140与壳本体111之间以及出水接头150与壳本体111之间可以采用相同的连接方式，也可以采用不同的连接方式。可选的，为了提高进水接头140和出水接头150的通用性，在一些实施例中，将进水接头140和出水接头150设置为相同材质，且结构相同，且进水接头140与壳本体111之间以及出水接头150与壳本体111之间采用相同的连接方式。
可以理解的是，壳本体111、进水接头140和出水接头150以及壳本体111为一体结构，可以结构简单，装配效率高，密封连接面1122少，分集水组件100的可靠性较高。
在另一些实施例中，如图20至图22所示，进水接头140和出水接头150与壳本体111可以为分离设置并组装连接的结构。具体而言，壳本体111设有进水通孔1114、进水通道101、回流通道121、出水通道102、出水通孔1115，出水通孔1115对应进水通道101的位置设置，并与进水通道101连通，出水通孔1115对应出水通道102设置，并与出水通道102连通，进水接头140与进水通孔1114密封连接，并形成密封连接处1116，出水接头150与出水通孔1115进行密封连接。其中，进水接头140可以通过焊接、铆接、压接或镶嵌到进水通孔1114，以与壳本体111密封连接，也可以使用胶圈、胶垫密封等与壳本体111密封连接；同理，出水接头150可以通过焊接、铆接、压接或镶嵌到出水通孔1115，以与壳本体111密封连接，也可以使用胶圈、胶垫密封等与壳本体111密封连接。
盘管换热器10根据使用环境和要求不同，换热组件200的结构不同，例如，可以是不带第一回水结构120的分集水组件100，也可以是带有第一回水结构120的分集水组件100，在带有第一回水结构120的分集水组件100中，第一回水结构120也可以不同。将进水接头140和出水接头150设置为与壳体110分体组装的形式，使得进水接头140和出水接头150可以作为通用件，进水接头140和出水接头150可以作为标准件，适用于不同形式的壳本体111中，这样，进水接头140和出水接头150可以大规模自动化批量成产，效率高、成本低。
在一些实施例中，分集水组件100上设置有排气组件160，排气组件160用于泄放水流路中的气体。排气组件160可以与出水通道102连通，具体的，如图12所示，排气组件160可以设置在出水接头150上；如图11所示，排气组件160也可以设置于壳本体111上，具体可以设置于顶板1112上，并与出水通道102对应。排气组件160可以是排气阀，排气组件160可以打开，以泄放水流路中的气体，排气组件160也可以关闭，使得排气组件160处密封设置，避免水流泄漏。
在一些实施例中，分集水组件100上设置有排水组件170，排气组件160用于泄放水流路中的水流。排水组件170可以与进水通道101连通，具体的，如图12所示，排水组件170可以设置在出水接头150上；如图11所示，排水组件170也可以设置于壳本体111上，具体可以设置于顶板1112上，并与进水通道101对应。排水组件170可以是排水阀，排水组件170可以打开，以泄放水流路中的气体，排水组件170也可以关闭，使得排水组件170处密封设置，避免水流泄漏。
需要说明的是，排气组件160与排水组件170的位置也可以互换。本实施例中，排气组件160可以设置于排水组件170的上方。本实施例通过将排气组件160与出水通道102连通，相较于排气组件160与进水通道101连通的形式，排气效果更好，可以使得换热组件200中的气体较多的排出，从而可提高换热效率。本实施例通过将排水组件170与进水通道101连通，有利于在换热组件200不使用时，将换热组件200内的水全部泄放。
如图28所示，本申请实施例还提供一种暖通设备，包括风机20以及本申请或本申请任意实施例提出的盘管换热器10，风机20设置于盘管换热器10的一侧。
具体的，风机20可以设置于换热组件200沿第二方向Y的一侧，风机20形成的气流的流动方向E与第二方向Y大致平行。
暖通设备还可以包括其他构件，例如，换热供水系统等，换热供水系统与盘管换热器10的连接可参照上文，在此不再赘述。
以上，仅为本申请较佳的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
