下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图2-图10，本发明实施例提供的换热器包括依次连接的三段分换热器，依次连接的三段分换热器分别为第一段分换热器1、第二段分换热器2和第三段分换热器3，每段分换热器均为板状结构，第一段分换热器1和第三段分换热器3分别与第二段分换热器2的两端连接，三段分换热器首尾相连形成整体的换热器。其中，第一段分换热器1和第三段分换热器3位于第二段分换热器2的同一侧，三段分换热器之间形成用于容置风叶4的风叶腔5，即三段分换热器共同围成的空间形成风叶腔5。
相邻的两段分换热器之间的折弯角度均指相邻的两段分换热器之间的朝向风叶腔5内部的夹角，即相邻的两段分换热器之间的折弯角度为其中一段分换热器在风叶腔5内部折至另一段分换热器所经过的角度。
重点在于，第一段分换热器1与第二段分换热器2之间的折弯角度为88-°110°，即第一段分换热器1与第二段分换热器2之间的位于风叶腔5内部的夹角为88-°110°。第三段分换热器3与第二段分换热器2的之间折弯角度为88-°110°，即第二段分换热器2与第三段分换热器3之间的位于风叶腔5内部的夹角为88-°110°。
应用本发明实施例提供的换热器时，将风叶4置于风叶腔5中且其进风侧朝向第二段分换热器2，第一段分换热器1和第二段分换热器2之间形成出风口，如此风叶的进风侧和左右两侧均具有分换热器，大大改善了风叶4进气不对称的情况，风叶4进气较对称，进而电机支架的受力较对称平衡，减小了震动降低了噪音。另外，第一段分换热器1与第二段分换热器2之间的折弯角度为88-°110°，第三段分换热器3与第二段分换热器2的之间折弯角度为88-°110°， 申请人经过多次试验得出，如此设置与现有技术相比，能够大大提高换热器的换热效率。

进一步地，上述第一种实施例中第一段分换热器1与第三段分换热器3之间的长度差值可以为10mm-150mm，以保证一些空调型号的专配需求。其中，第一段分换热器1的长度是指其与第二段分换热器2连接的一端至远离第二段分换热器2的一端的距离，第三段分换热器3的长度是指其与第二段分换热器2连接的一端至远离第二段分换热器2的一端的距离。如图3所示，其为第三段分换热器3的长度大于第一段分换热器1的情况。如图4所示，其为第一段分换热器1的长度大于第三段分换热器3的情况。

在上述第二种实施例中，第一段分换热器1和第二段分换热器2的长度可以均为50mm-350mm，如此保证了风叶4两侧的风流换热对称，减小了支架的震动且降低了噪音。当然，第一段分换热器1和第二段分换热器2的长度还可以根据实际情况自行设定，比如为360mm等，在此不作限定。
进一步地，上述第二种实施例中第一段分换热器1与第三段分换热器3之间的长度差值可以为10mm-150mm，以保证一些空调型号的专配需求。其中，第一段分换热器1的长度是指其与第二段分换热器2连接的一端至远离第二段分 换热器2的一端的距离，第三段分换热器3的长度是指其与第二段分换热器2连接的一端至远离第二段分换热器2的一端的距离。如图6所示，其为第三段分换热器3的长度大于第一段分换热器1的情况。如图7所示，其为第一段分换热器1的长度大于第三段分换热器3的情况。
如图8-10所示，在本发明的第三种实施例中，该换热器还包括与第一段分换热器1的远离第二段分换热器2的一端连接的第四段分换热器6以及与第三段分换热器3的远离第二段分换热器2的一端连接的第五段分换热器3，即第一段分换热器1一端与第二段分换热器2连接，另一端与第四段分换热器6连接，第三段分换热器3一端与第二段分换热器2连接，另一端与第五段分换热器3连接。并且，第四段分换热器6与第一段分换热器1之间的折弯角度为170-°180°，第五段分换热器3与第三段分换热器3之间的折弯角度为170-°180°。该处的折弯角度是指相邻的两段分换热器之间的朝向风叶腔5内部的夹角。如此可以改善风叶4左右的风场分布，提高换热性能。
进一步地，上述第三种实施例中，第一段分换热器1和第二段分换热器2的长度均为30mm-300mm，第四段分换热器6和第五段分换热器3的长度均大于30mm。如此保证了风叶4两侧的风流换热对称，减小了支架的震动且降低了噪音。当然，第一段分换热器1、第二段分换热器2、第四段分换热器6和第五段分换热器3的长度还可以根据实际情况自行设定，比如为320mm等，在此不作限定。其中，第四段分换热器6的长度是指其与第一段分换热器1的一端至远离第一段分换热器1的一端的距离，第五段分换热器3的长度是指其与第三段分换热器3的一端至远离第三段分换热器3的一端的距离。
进一步地，上述第三种实施例中第四段分换热器6与第五段分换热器3之间的长度差值为10mm-150mm，以保证一些空调型号的专配需求。如图9所示，其为第五段分换热器3的长度大于第四段分换热器6的情况。如图10所示，其为第四段分换热器6的长度大于第五段分换热器3的情况。
基于上述实施例中提供的换热器，本发明还提供了一种室外机，该室外机包括上述实施例中任意一种换热器。由于该室外机采用了上述实施例中的换热器，所以该室外机的有益效果请参考上述实施例。
本发明还提供了一种空调器，该空调器包括上述的室外机，因此该空调器的有益效果请参考上述实施例。
本说明书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。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
