具体实施方式
下面结合附图及具体实施方式对本发明做进一步说明。
参见图6至图23，根据本发明的实施例的换热器100包括第一换热器芯体101。所述第一换热器芯体101包括：多个沿第一方向D1延伸的诸如扁管的换热管10；以及在第二方向D2上与换热管10交替排列的多个翅片20。所述翅片20包括沿第一方向D1排列的多 个翅片单元21。所述翅片单元21包括：翅片单元主体210；以及与翅片单元主体210连接的开窗片211，至少一些开窗片211与由第一方向D1和第三方向D3限定的平面的夹角小于或等于45度，第三方向D3与第一方向D1和第二方向D2垂直。第一方向D1和第二方向D2可以相互垂直。换热管10可以是扁管，第一方向D1和第三方向D3限定的平面可以平行于图6中的换热管10的与翅片20接触的表面。第三方向D3可以是换热管10的宽度方向。例如，至少一些开窗片的长度方向与由第一方向和第三方向限定的平面的夹角小于或等于45度。在图6所示的实施例中，换热器100只包括一个换热器芯体，换热器100还包括集流管5，换热管10的两端与集流管5连接并流体连通。
参见图6至图23，根据本发明的实施例，至少一个翅片20的至少一个翅片单元21的翅片单元主体210平行于第二方向D2。在图中所示的实施例中，所有翅片单元主体210大致平行于第二方向D2。显然，至少一个翅片20的至少一个翅片单元21的翅片单元主体210也可以相对于第二方向D2倾斜。
参见图6至图23，根据本发明的实施例，所述开窗片211与所述翅片单元主体210的夹角介于60度至90度之间，例如所述开窗片211与所述翅片单元主体210的夹角可以介于85度至90度之间，或者所述开窗片211与所述翅片单元主体210垂直。从所述第三方向D3观看时，所述翅片20具有矩形波状的形状或类正弦波状的形状。至少一个翅片20的所述多个翅片单元21的开窗片211可以具有相同的宽度。翅片单元21可以是多个单独的翅片单元21，每一个翅片单元21可以通过与翅片单元21连接的连接部焊接于换热管。此外，所述翅片20可以具有矩形波状的形状，即翅片是一体的，在这种情况下，将相邻的翅片单元21连接的连接部(例如，平直的部分)焊接于换热管，而平直的翅片单元21连接在连接部之间。如果所述翅片20具有波状的形状，例如类正弦波状的形状，即翅片是一体的，在这种情况下，将相邻的翅片单元21连接的连接部(例如，曲面状的部分)焊接于换热管，而平直的翅片单元21连接在连接部之间。
参见图7、图8、图11至图13、图16至图18，根据本发明的实施例，所述翅片单元21还包括形成在翅片单元主体210中的多个开口212，所述开口212具有开口边缘215，所述开窗片211从开口边缘215突出。
参见图7、图8、图10、图12、图13、图15、图17、图18、图20、图21，根据本发明的实施例，所述翅片单元21包括多排开窗片211，每一排开窗片211包括沿第二方向D2排列的多个相互平行的开窗片211。多排开窗片211中的相邻两排开窗片211在第三方向上间隔开。
参见图12、图13、图15，根据本发明的实施例，从第一方向D1观看时，从翅片单元主体210的第二方向D2上的一侧到另一侧每一行开窗片211总体呈波状形状。多排开窗片211中的相邻两排开窗片211在第三方向上间隔开。所述开窗片211可以具有平行四边形的形状。翅片单元主体210可以大致在一个平面中。根据本发明的实施例，风在流经翅片时，沿S形的路径流动。由此，在不影响排水性能的情况下，能够增加对风的扰动，增加风的行程，从而增强换热性能。
参见图6至图16，根据本发明的实施例，所述翅片单元主体210具有平面状的形状。即，翅片单元主体210大致在一个平面中。
参见图17、图18、图21，根据本发明的实施例，所述翅片单元主体210具有在第三方向D3上相互连接的多个翅片单元主体段210S，并且在从所述翅片单元主体210的第二方向D2上的一个边缘2101向另一个边缘2102的方向上观看时，所述翅片单元主体210具有波状折线的形状。在图中所示的实施例中，在第二方向D2上观看时，所述翅片单元主体210具有波状折线的形状。相对于第二方向D2和第三方向D3限定的平面，所述翅片单元主体210的多个翅片单元主体段210S可以以小于或等于45度的角度倾斜。根据本发明的实施例，翅片单元主体210具有波状形状，风在流经翅片时，沿S形的路径流动。由此，在不影响排水性能的情况下，能够增加对风的扰动，增加风的行程，从而增强换热性能。
例如，图12至16中所示的实施例与图17至图21中所示的实施例可以进行组合形成新的实施例，在这种情况下，从第一方向D1观看时，从翅片单元主体210的第二方向D2上的一侧到另一侧每一行开窗片211总体呈波状形状，同时所述翅片单元主体210具有在第三方向D3上相互连接的多个翅片单元主体段210S，并且在从所述翅片单元主体210的第二方向D2上的一个边缘2101向另一个边缘2102的方向上观看时，所述翅片单元主体210具有波状的形状。根据本发明的实施例，在多个风向上对风进行扰流，由此进一步增强了换热性能。
根据本发明的实施例，至少一个翅片20的至少一个翅片单元21的开窗片211朝向换热器100的第一方向D1上的同一侧突出。
参见图7、图8、图17、图18、图21，根据本发明的实施例，所述开窗片211可以具有矩形形状。所述开窗片211也可以具有平行四边形的形状等任何合适的形状。
参见图9、图11、图14、图16、图19、图21，根据本发明的实施例，所述开窗片211具有与翅片单元主体210连接的第一边缘2111，以及与第一边缘2111相对的第二边缘2112，并且对于至少一个翅片20，假设所述多个翅片单元21从换热器100的第一方向D1上的一侧到另一侧依次排列，除了最后一个翅片单元21之外的其它翅片单元21中的至少一个翅片单元21的至少一个开窗片211朝向所述换热器100的所述另一侧突出并且所述至少一个开窗片211的第二边缘2112与下一个翅片单元21的翅片单元主体210相邻或接触。在本发明的一些示例中，所述至少一个开窗片211的第二边缘2112与下一个翅片单元21的翅片单元主体210间隔一定距离，使得在所述至少一个开窗片211的第二边缘2112与下一个翅片单元21的翅片单元主体210之间可形成水桥。由此，在翅片单元21上形成较小的水珠时，水珠可通过上层的翅片单元21的开窗片211流到下层翅片单元21的翅片单元主体210或开窗片211，从而实现排水功能。此外，减小了水珠对风与翅片换热的阻碍，在强化排水功能的同时，增强了换热性能。
在本发明的一些实施例中，从所述第三方向D3观看时，所述翅片20具有矩形波状的形状，可以使多个开窗片211从翅片单元突出的高度相同，便于形成多个排水通道，便于加工。
参见图22、图23，根据本发明的实施例，所述翅片20是第一翅片20，并且所述第一换热器芯体101还包括：在第二方向D2上与换热管10交替排列的多个第二翅片30，第一翅片20和第二翅片30在第三方向D3上并排设置，并且第二翅片30位于第一翅片20的在第三方向D3上的一侧。
参见图22、图23，根据本发明的实施例，所述第二翅片30包括：沿第一方向D1排列的多个翅片单元31，所述翅片单元31包括：翅片单元主体310；以及与翅片单元主体310连接的开窗片311，至少一些开窗片311与由第一方向D1和第三方向D3限定的平面的夹角大于45度，以增加翅片对风的扰动，提高换热性能。例如，至少一些开窗片311的长度方向与由第一方向D1和第三方向D3限定的平面的夹角大于45度。从所述第三方向D3观看时，所述第二翅片30可以具有波状的形状，例如类正弦波状的形状。例如，所述第二翅片30可以是背景技术中提到的传统的波浪形翅片。因此，根据图22，图23所示实施例的换热器100在强化排水功能的同时，增强了换热性能。
根据本发明的实施例，所述换热器100还包括：第二换热器芯体，所述第二换热器芯体位于第一换热器芯体101的在第三方向D3上的一侧。根据本发明的实施例，第二换热器芯体包括：多个沿第一方向延伸的换热管；以及在第二方向上与换热管交替排列的多个翅片，所述第二换热器芯体的所述翅片包括：沿第一方向排列的多个翅片单元，所述翅片单元包括：翅片单元主体；以及与翅片单元主体连接的开窗片，至少一些开窗片与由第一方向和第三方向限定的平面的夹角大于45度，以增加翅片对风的扰动，提高换热性能。例如，至少一些开窗片的长度方向与由第一方向和第三方向限定的平面的夹角大于45度。根据本发明的实施例，从所述第三方向D3观看时，所述第二换热器芯体的翅片具有波状的形状，例如类正弦波状的形 状。该实施例可以通过将背景技术中提到的图1中的换热器的两个换热器芯体中的一个换热器芯体的翅片20′替换成根据本发明的实施例的翅片20(例如图6中的翅片20)而形成。因此，根据本发明的实施例的换热器100在强化排水功能的同时，增强了换热性能。
根据本发明的实施例的换热器在作为蒸发器使用时具有增强的排水性能。
根据本发明的实施例的换热器在实际应用中，换热器可以是单排换热器，双排换热器或者多排换热器，并可以用作蒸发器。对于单排换热器，局部的翅片可以采用翅片20，其他部分的翅片可以采用翅片30(例如，背景技术中提到的传统的波浪形翅片)。对于双排换热器或者多排换热器，部分排的换热器芯体可以采用翅片20，而其他排的换热器芯体可以采用翅片30(例如，背景技术中提到的传统的波浪形翅片)。
根据本发明的实施例的换热器在作为蒸发器使用时，对于单排换热器，迎风侧的翅片可以采用翅片20，背风侧的翅片可以采用翅片30(例如，背景技术中提到的传统的波浪形翅片)。对于双排换热器或者多排换热器，迎风侧的一排或者多排的换热器芯体可以采用翅片20，而背风侧的一排或者多排换热器芯体可以采用翅片30(例如，背景技术中提到的传统的波浪形翅片)。
通过上述布置方式，空气经过换热器时，先经过利于排水的翅片20，换热的同时降低空气湿度，然后通过翅片30再次换热。从而达到换热效率的最大化。
尽管描述了上述实施例，但是上述实施例中的一些特征可以进行组合形成新的实施例。此外，上述实施例中的一些实施例也可以进行组合形成新的实施例。
