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之间横向流动，如图1所示的，在换热器1的两侧，空气/风的横向流动增强，使得空气和换热器的翅片接触面积减小，同时，两侧的横向流动使两侧的风阻增大，风速降低，风量下降，造成换热量下降，影响换热效果和换热效率。针对上述技术问题，本发明提出了如下示例性的换热器结构，在现有换热器的基础上，优化空气流动路径，提高换热效率。
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：一个或多个裂隙翅片11，每个所述裂隙翅片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；一个或多个平板翅片12，每个所述平板翅片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。
上述方案中，平板翅片12之间设置一个或多个裂隙翅11片，例如裂隙翅片11和平板翅片12可以平行安装，在裂隙翅片11和平板翅片12的通孔中安装换热管。图3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3所示的换热器的平板翅片12设置和裂隙翅片相对应的通孔，和裂隙翅片相比较的区别在于，平板翅片12的相邻的通孔之间无裂隙，空气仅能在两个平板翅片12之间的各个裂隙翅片11之间进行流通，使得两个相邻的平板翅片11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。
换热器的裂隙翅片和平板翅片的安装结构可以有多种。作为示例，相邻 的所述平板翅片之间的间距相同，相邻的所述平板翅片之间的所述裂隙翅片的数量相同。
上述方案中，和现有的等间距裂隙翅片换热器相比，本发明实施例的换热器在现有的等间距裂隙翅片换热器的结构基础上，使用平板翅片替换一个或多个裂隙翅片，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。
作为另一示例，相邻的所述平板翅片之间的间距相同，从所述换热器的中间到两侧，相邻的所述平板翅片之间的所述裂隙翅片的数量逐渐减少。
上述方案中，设置换热器从中间向两侧的两个相邻的平板翅片之间的裂隙翅片的数量逐渐减少，空气流动的风阻减小，使得两侧的空气量/风量增加，改善两侧的换热效率，整体提高换热器的换热效率，改善换热效果。
图4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4所示，本发明一种实施方式的换热器，一个或多个所述平板翅片的所述通孔之间预留裂隙冲压片13，所述裂隙冲压片13移除后形成所述裂隙，所述裂隙连通相邻的所述通孔。
上述方案中，裂隙冲压片13通过冲压工艺形成，冲压过程中不完全冲断，可以沿冲压切口对裂隙冲压片13施加外力，使裂隙冲压片13移除，形成一部分通孔联通的平板翅片，或将平板翅片12的所有通孔之间的裂隙冲压片13均移除，形成与裂隙翅片11相同的结构。
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。
图5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5所示，本发明一种实施方式的换热器，从所述换热器的出风侧到所述换热器的进风侧，所述裂隙翅片11的密度成阶梯式减小。
上述方案中，在换热器的进风侧易聚集较多的凝结水，凝结水膜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，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(图中未示出)。
上述示例的裂缝翅片的排布方式，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(图中未示出)。
上述示例的平板翅片的排布方式，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。
上述方案中，从所述换热器的出风侧到所述换热器的进风侧，所述裂隙翅片的密度按照大于或等于两个梯度成阶梯式减小。
作为示例，设置裂隙翅片的密度按照三个梯度成阶梯式减小，在换热器的进风侧设置翅片间距为D1，在出风侧设置翅片间距为D3，在进风侧和出风侧之间的区域设置翅片间距为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。
上述方案中，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。
上述示例性实施例的换热器，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一方面，提供了一种空调器，包括上述任一种换热器。
