具体实施方式
根据本发明的实施例的空调系统包括换热器。下面具体描述根据本发明的实施例的换热器。
图1是根据本发明的实施例的换热器的子换热器的示意透视图；图2是根据本发明的一个实施例的换热器的示意透视图；以及图3是 根据本发明的另一个实施例的换热器的示意透视图。需要说明的是，为了清楚图示换热器，图中没有示出翅片。
参见图1、图2和图3，根据本发明的实施例的换热器100包括两个子换热器1，两个子换热器1中的每一个包括：两个L形的集流管11，每个集流管11包括两个直段111以及在两个直段111之间的折弯段112；以及在两个集流管11之间沿预定方向延伸的换热管12。两个子换热器1中的每一个还可以包括：与换热管12交替排列并且沿所述预定方向延伸的翅片，翅片可以是波浪状的翅片。两个子换热器1的位于换热管12一侧的两个集流管11的直段111分别沿四边形的四个边延伸，两个子换热器1的位于换热管12另一侧的两个集流管11的直段111分别沿四边形的四个边延伸。四边形可以是矩形、菱形等。集流管11的两个直段111之间的夹角可以在20度至170度之间。
在本发明的实施例中，参见图1、2，两个子换热器1的在换热管12排列方向上的至少一对相邻的边缘13邻接。例如，两个子换热器1的在换热管12排列方向上的至少一对相邻的边缘13中的至少一个设有细长的连接件131。所述细长的连接件131的两端分别与子换热器1的两个集流管11连接，或者所述细长的连接件131与子换热器1的翅片连接，例如，与子换热器1的最外侧的翅片连接。细长的连接件131可以由板冲压形成，细长的连接件131可以是子换热器的边板，或与子换热器的边板类似的元件。通常边板是扁平的，边板也可以具有L形的截面，便于两个边板之间的连接。两个子换热器1的在换热管12排列方向上的至少一对相邻的边缘13可以通过细长的连接件131连接，例如，两个子换热器1的在换热管12排列方向上的两对相邻的边缘13都可以通过细长的连接件131连接。细长的连接件131与集流管11的连接方式或细长的连接件131之间的连接方式包括但不限于焊接，螺纹连接，铆接，卡接，胶接等。
在本发明的实施例中，参见图1、图3，换热器100还包括第一挡风板5，所述第一挡风板5的在换热管12排列方向上相对的两个边缘51中的每一个与两个子换热器1的在换热管12排列方向上的一 对相邻的边缘13中的对应的一个交叠。根据本公开的示例，两个子换热器1的在换热管12排列方向上的至少一对相邻的边缘13分别设有细长的连接件131；并且所述第一挡风板5的在换热管12排列方向上相对的两个边缘51中的每一个与细长的连接件131中的对应的一个交叠并连接。换热器100还可以包括第二挡风板，所述第二挡风板的在换热管12排列方向上相对的两个边缘中的每一个与两个子换热器1的在换热管排列方向上的另一对相邻的边缘中的对应的一个交叠。挡风板与细长的连接件131的连接方式包括但不限于焊接，螺纹连接，铆接，卡接，胶接等。在图3中所示的实施例中，挡风板与细长的连接件131通过螺钉6连接。
在本发明的实施例中，参见图1、图3，换热器100还包括三通2，两个子换热器1的位于换热管12的一侧的两个集流管11的一对相邻的端部113与三通2的两个管21连接，并且三通2的另一个管21作为换热器100的入口管或出口管。两个子换热器1的位于换热管12的所述一侧的两个集流管11的另一对相邻的端部113可以通过连接管3相互连接。采用该设置，可以方便换热器100与阀或压缩机等其它部件相联。此外，采用该设置，还使换热器100中的换热介质的压降更低，换热介质在集流管中的流速更低，从而压降也低，有利于提高换热量。此外，在图3所示的实施例中，两个子换热器1的位于换热管12的另一侧的两个集流管11也可以采用相同的方式进行连接。
根据本发明的换热器，两个子换热器1可以是大致对称的。两个子换热器1的外观几乎一样，使用几乎相同规格和数量的换热管，翅片等，两个子换热器1的折弯方向相反。由此，需要的零件种类数更少，工装更少，由此成本更低。由于两个子换热器1相类似，因此，两个子换热器1中的换热介质分配更均匀。
根据本发明的换热器可靠性好，因为换热管不折弯，仅仅是集流管折弯。此外，根据本发明的换热器报废率低，并且折弯后的尺寸易于控制，并且报废成本低，因为在一个子换热器1失效时可以仅仅更换一个子换热器1。再者，根据本发明的换热器易于加工并且组装 方便，因为子换热器1仅有一个折弯段。此外由于根据本发明的子换热器1可以堆叠放置，因此，运输和存储方便。
根据本发明的换热器由于子换热器1的边缘邻接或子换热器1的边缘与挡风板交叠并连接，因此防止在子换热器1之间漏风。
此外，根据本发明的上述实施例可以组合成新的实施例。
