具体实施方式
以下描述和附图充分地示出本发明的具体实施方案，以使本领域的技术人员能够实践它们。其他实施方案可以包括结构的、逻辑的、电气的、过程的以及其他的改变。实施例仅代表可能的变化。除非明确要求，否则单独的部件和功能是可选的，并且操作的顺序可以变化。一些实施方案的部分和特征可以被包括在或替换其他实施方案的部分和特征。本发明的实施方案的范围包括权利要求书的整个范围，以及权利要求书的所有可获得的等同物。在本文中，各实施方案可以被单独地或总地用术语“发明”来表示，这仅仅是为了方 便，并且如果事实上公开了超过一个的发明，不是要自动地限制该应用的范围为任何单个发明或发明构思。本文中，诸如第一和第二等之类的关系术语仅仅用于将一个实体或者操作与另一个实体或操作区分开来，而不要求或者暗示这些实体或操作之间存在任何实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法或者设备中还存在另外的相同要素。本文中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。对于实施例公开的方法、产品等而言，由于其与实施例公开的方法部分相对应，所以描述的比较简单，相关之处参见方法部分说明即可。
图1是现有技术的换热器结构示意图。如图1所示的现有技术的换热器1包括一个或多个等间距设置的裂隙翅片11，电机2转动带动风机转动，使空气沿图中箭头所示方向进入换热器1，换热管垂直于换热器1的裂隙翅片方向穿入裂隙翅片的通孔中，裂隙翅片11上的裂隙联通各个通孔，使得空气/风可以在各个裂隙翅片11之间流动，如图1所示的，在换热器1的进风侧，易形成凝结水，凝结水膜形成水桥，使得翅片之间间距减小，进风侧的风阻增大，进风量减少，出风侧的风量也相应减少，换热器的整体换热量减少，影响换热效果。
图2是根据一示例性实施例示出的本发明一种实施方式的换热器结构示意图。如图2所示，本发明一种实施方式的换热器1，包括：一个或多个翅片，从所述换热器1的出风侧到所述换热器的进风侧，所述翅片的密度逐渐减小。
上述方案中，箭头方向即空气/风的方向，在换热器的进风侧易聚集较多的凝结水，凝结水膜形成水桥导致进风侧翅片间距减小，风量下降，出风侧的风量将明显减少，影响换热器的换热效果。本实施例通过设置换热器的翅片从出风侧到进风侧逐渐减少，间距逐渐增大来降低进风侧的凝结水形成水桥造成得翅片间距减小的负面影响，使得空气/风在进风侧的风阻降低，顺利进入换热器的翅片之间，并从出风侧顺利流出，提高换热器的空气流通能力，改善换热效果，提高换热效率。
上述方案中，翅片例如可以为现有技术采用的裂隙翅片11。
在一些可选实施例中，从所述换热器的出风侧到所述换热器的进风侧，所述翅片的密度成阶梯式减小。
上述方案中，例如可以设置翅片间距从出风侧向进风侧成阶梯式递减，在不同的区域段设置翅片间距不同，生产时按照区域段安装不同密度的翅片，生产制造过程易于实现。
作为示例，在所述换热器的进风侧，所述翅片的间距为D1，在所述换热器的出风侧，所述翅片的间距为D3，在所述换热器的出风侧和所述换热器的进风侧之间的区域，所述翅片的间距为D2，其中，D1＞D2＞D3。
作为进一步示例，所述D1、D2和D3的关系为：3*D1＝4*D2＝6*D3。
图3是根据另一示例性实施例示出的本发明一种实施方式的换热器结构示意图。如图3所示，本发明一种实施方式的换热器，所述一个或多个翅片分为一个或多个分区，每个所述分区中的多个所述翅片的长度沿所述换热器的出风侧到所述换热器的进风侧逐渐增加。
上述方案中，从进风侧到出风侧形成外形为阶梯状的翅片排布结构，在进风侧具有较为稀疏的翅片密度，在出风侧的翅片密度大于进风侧，使空气/风易于从进风侧进入并发散至出风侧的各个翅片之间，减少进风侧凝结水的聚集，降低换热器的风阻，提高进风量和换热器，提高换热效率。
上述方案中，所述一个或多个翅片包括一个或多个裂隙翅片11和一个或多个平板翅片12；
其中，每个所述裂隙翅片11上设置一个或多个通孔，所述通孔用于通过换热管，相邻的所述通孔之间通过裂隙连通，以使得空气可以在相邻的所述裂隙翅片11的所述裂隙之间流通；
每个所述平板翅片12上设置一个或多个通孔，所述通孔用于通过换热管，每个所述平板翅片12设置在相邻的一个或多个所述裂隙翅片11之间，以使得两个相邻的所述平板翅片12之间的一个或多个所述裂隙翅片11形成空气流通区。
图4是根据一示例性实施例示出的本发明一种实施方式的换热器的平板翅片的结构示意图。如图4所示，本发明一种实施方式的换热器的平板翅片，在现有的裂隙翅片结构相比，其通孔之间无裂隙。
作为示例，每个分区中设多个裂隙翅片，最长翅片即平板翅片长度为a；最短裂隙翅片长度为b，翅片分区长度为c，a、b和c的数值关系为：
2/3*c≥a-b≥1/2*c
上述方案中，当翅片长度差较大时，则每个分区中的较短长度翅片长度过于短，影响换热器的换热量；当翅片长度差较小时，无法形成有效的梯度，易形成凝结水；依据 上述公式设置每个分区的翅片长度差不小于每个分区长度的1/2，且不大于每个分区长度的2/3，使得分区中的最短翅片长度不至于较短以影响换热效果，同时确保梯度不至于较小而形成凝结水。
上述方案中，每个所述分区中的最长的所述翅片为平板翅片12。将平板翅片12作为分区的间隔翅片。在平板翅片12之间设置一个或多个裂隙翅片11，例如裂隙翅片和平板翅片可以平行安装，在裂隙翅片和平板翅片的通孔中安装换热管，平板翅片无裂隙，空气在两个平板翅片之间的各个裂隙翅片之间进行流通，使得两个相邻的平板翅片之间形成独立的空气流通区，在换热器的垂直于空气流向的方向上，形成一个或多个由两两的平板翅片形成的空气流通区，空气在各个空气流通区内流动。和图1所示的现有技术的换热器的空气流向相比，对于现有的均是裂隙翅片构成的换热器，本发明实施例的换热器，可有效改善换热器两侧空气横向流动造成的两侧的风量流失，优化空气流通路径，改善换热器换热效果，提高换热效率。
上述方案中，作为示例，相邻的所述平板翅片之间的距离相同。各个相邻的平板翅片间距相同，使得形成一个或多个相同的空气流通区，使得空气与各个空气流通区的翅片的接触均匀分布。改善两侧风量的横向流动，优化尤其是换热器两侧的空气流动路径，提高换热器的整体的换热效果，提高换热效率。
图5是根据另一示例性实施例示出的本发明一种实施方式的换热器的平板翅片的结构示意图。如图5所示，本发明一种实施方式的换热器，所述平板翅片的所述通孔之间预留裂隙冲压片，所述裂隙冲压片移除后形成所述裂隙，所述裂隙连通相邻的所述通孔。
上述示例中，平板翅片的通孔之间预留裂隙冲压片，在移除裂隙冲压片之后，形成与裂隙翅片相同的结构，在安装使用中，可以根据实际运行的工况，在必要时，移除平板翅片的裂隙冲压片，使得相邻的空气流通区连通，变换换热器的空气流通路径，灵活调节换热器的工作模式以适用于不同的场景/环境，使得换热器的应用范围更加广泛。
上述方案中，作为翅片排列方式的另一示例，从所述换热器的中间到两侧，相邻的所述裂隙翅片之间的距离逐渐增大。
上述换热器翅片的排布方式，因为空气/风由换热器的两侧向中间位置靠拢，使得在换热器中间位置，空气/风的横向流动较小，而在换热器两侧，空气/风的横向流动较明显，在两侧设置较小的裂隙翅片间距，利于减小换热器两侧的风阻，增加换热器两侧的风量，使得换热器两侧的换热量增加，提高换热效率，改善换热效果。
作为另一示例，从所述换热器的中间到两侧，相邻的所述平板翅片之间的距离逐渐减 小。
因为空气/风由换热器的两侧向中间位置靠拢，使得在换热器中间位置，空气/风的横向流动较小，而在换热器两侧，空气/风的横向流动较明显，上述示例的平板翅片的排布方式，在两侧设置较小的平板翅片间距，对翅片间空气/风的横向流动的阻隔作用更加明显，减小风阻，增加风量，进一步改善换热效果，提高换热效果。
上述各示例性实施例的换热器，所述换热器的一个或多个所述裂隙翅片和/或一个或多个所述平板翅片活动安装，间距可调节。各个裂隙翅片和/或平板翅片不固定安装，可沿通孔横向移动，实现翅片间的间距可调节，适用于不同安装环境，及不同性能参数的空调器，提高换热器的通用性。
根据本发明实施例的第二方面，提供了一种空调器，包括：上述任一种换热器。
