具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例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。
一般地，热泵汽车空调中的外侧换热器，一般都竖立固定地放置在车辆前，家用机亦是如此。同时由于平行流换热器的管路采用扁管，在扁管之间设置有波纹散热片，当换热器的波纹散热片上凝结冷凝水后，就容易积聚在扁管及散热片之间的间隙中，不容易排出；换热器的设置方式及平行流换热器本身的结 构形式综合导致了平行流换热器的排水性能差，受此限制，平行流换热器大部分仅使用于单冷机组外侧换热器上，不适用热泵空调。
如图1和图2所示，一汽车空调外侧换热器(例如：图1和图2所示的外侧换热器1)位于汽车的前端，故在汽车运行时外侧换热器表面会形成较高的空气流动速度。当热泵汽车空调进入除霜模式后，外侧换热器表面高速流动的空气会带走用于除霜的大量热量，不仅导致热泵空调系统热量浪费，而且会严重影响热泵汽车空调除霜效果，甚至导致无法除霜的现象，影响车内乘客舒适性。
根据本发明的实施例，提供了一种换热控制装置，如图3所示本发明的换热控制装置的一实施例的结构示意图。该换热控制装置可以包括：旋转装置。
其中，所述旋转装置，可以用于按设定的第一定旋转方向，使待控空调的外侧换热器1旋转至倾斜位置，以利用所述外侧换热器1表面凝结的冷凝水和/或除霜水的重力、以及所述外侧换热器1的外部流动空气，使所述外侧换热器1表面凝结的冷凝水和/或化霜水排出。
例如：如图5所示，当热泵汽车空调进入除霜模式后，程序控制驱动电机2带动外侧换热器1旋转至横向平放位置。
由此，通过旋转装置，将外侧换热器旋转至倾斜或者横向位置，从而可借助重力作用以及换热器表面的空气流动影响，使外侧平行流换热器表面凝结的冷凝水和除霜水及时自行排出，减小外侧换热器风阻，提升换热性能。
可选地，所述待控空调，可以包括：热泵汽车空调。
可选地，当所述待控空调可以包括热泵汽车空调时，所述外侧换热器1，设置于所述热泵汽车空调的前侧迎风面。
例如：外侧换热器1放置在汽车空调前侧迎风面。
由此，通过将外侧换热器设置在汽车空调前侧迎风面，换热方便、且高效。
可选地，当所述待控空调可以包括热泵汽车空调时，所述第一旋转方向，可以包括：使所述外侧换热器1的上部向所述汽车的车尾方向旋转、且使所述外侧换热器1的下部向所述汽车的车头方向旋转的方向。
例如：外侧换热器倾斜时，可以是外侧换热器上部向内(即车尾方向)，换热器下部向外(即车头方向)进行旋转倾斜。
可选地，当所述待控空调可以包括热泵汽车空调时，所述室外换热器的外 部流动空气，可以包括：所述热泵汽车空调所属汽车的车头前侧流动空气。
由此，通过使外侧换热器上部向车尾方向倾斜、下部向车头方向倾斜，有利于排水，且排水效率高，换热性能好。
可选地，所述外侧换热器1，可以包括：平行流换热器。
由此，通过平行流换热器，占用空间小，换热效率高。
在一个可选例子中，所述旋转装置，还可以用于按与所述第一旋转方向相反的第二旋转方向，使所述外侧换热器1旋转至竖立位置，以加大所述外侧换热器1的外部流动空气的流量，使所述外侧换热器1正常换热。
例如：当热泵汽车空调完成除霜后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
例如：如图6所示，当热泵汽车空调进入制冷模式后，程序控制驱动电机2带动外侧换热器1旋转至竖立位置。
由此，通过使外侧换热器旋转至竖立位置，可以提升外侧换热器表面空气流量，从而进行正常换热，换热效率高。
其中，所述竖立位置与所述倾斜位置之间的夹角，大于或等于15°、且小于或等于90°。
例如：外侧换热器1在竖直位置和倾斜位置之间的夹角为α，其中15°≤α≤90°。
由此，通过合理的倾斜角度，可以提升排水便捷性和高效性。
可选地，所述旋转装置使待控空调的外侧换热器1旋转至倾斜位置、并使所述外侧换热器1旋转至竖立位置，可以包括：
(11)在所述待控空调进入制热模式或化霜模式后，使所述外侧换热器1旋转至所述倾斜位置。以及，
例如：在热泵汽车空调制热运行时，通过控制热泵汽车空调外侧平行流换热器旋转至倾斜位置，可以有效排出外侧平行流换热器表面凝结的水，减小换热器风阻，提高换热性能。
例如：热泵汽车空调需要进入除霜模式后，控制热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，让外侧平行流换热器表面的霜融化后的除霜水因为重力作用可以及时自行排出，不会重新凝结成冰霜，确保热泵空 调正常制热运行。
例如：在热泵汽车空调进入化霜后，由于热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，换热器在车前侧的空气流动方向上面积变小，流经换热器表面的空气流量相应降低，可以减少流动空气带走换热器表面用于除霜的热量，有效加快除霜速度，提高除霜效果。
例如：在热泵汽车空调的制热模式或者除霜模式运行时，将外侧换热器进行旋转，至倾斜位置或者横向平放位置，可以加快排出外侧换热器表面的冷凝水和除霜水，有效提高热泵汽车空调的性能、可靠性。
例如：外侧换热器1在进入除霜模式后也可以处于倾斜位置，外侧换热器1在竖直位置和倾斜位置之间的夹角为α，其中15°≤α≤90°。
(12)在所述待控空调在所述制热模式下、且所述外侧换热器1表面凝结的冷凝水后排出后，或在所述待控空调在所述化霜模式下、且所述外侧换热器1表面霜层融化后形成的化霜水排出后，或在所述待控空调在所述化霜模式下完成化霜后，再使所述外侧换热器1旋转至所述竖立位置。
例如：完成冷凝水排出后再将外侧平行流换热器旋转至竖立位置，不影响换热器正常换热。
例如：当化霜运行结束后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
由此，通过根据空调所处模式使外侧换热器旋转至倾斜位置或竖立位置，可以使相应模式下外侧换热器表面的阻力减小、换热性能和运行性能都得以提升，有利于提升空调运行的节能性和可靠性。
或者，所述旋转装置使待控空调的外侧换热器1旋转至倾斜位置、并使所述外侧换热器1旋转至竖立位置，还可以包括：
(21)在所述待控空调进入制热模式后，使所述外侧换热器1旋转至所述倾斜位置并保持第一设定时长。以及，
(22)所述第一设定时长到达后，再使所述外侧换热器1旋转至所述竖立位置并保持第二设定时长。以及，
(23)所述第二设定时长到达后，再使所述外侧换热器1旋转至所述倾斜位置并保持所述第一设定时长。
例如：热泵空调在制热运行时，程序控制驱动电机按一定的周期将外侧平行流换热器旋转至倾斜位置，将外侧换热器表面凝结到一定程度的冷凝水后可及时自行排出，可以减小换热器风阻，提高换热性能。
例如：程序控制驱动电机2也可以按一定的周期将外侧换热器1从竖立位置旋转至倾斜位置保持时间T1，T1时间之后再反向旋转为竖立位置，外侧换热器1在竖立位置保持时间T2，T2时间后再旋转为倾斜位置，如此往复旋转运行。外侧换热器1在处于倾斜位置保持时间T1，可以使外侧换热器1上凝结的冷凝水后进行排出；外侧换热器1恢复旋转为竖立位置后，可以提高外侧换热器1表面的空气流量，确保外侧换热器1的换热性能。
由此，通过定期使外侧换热器旋转至倾斜位置或竖立位置，可以定期排水，有利于提升空调运行的可靠性和换热效果。
在一个可选例子中，所述旋转装置的数量为两个。两个所述旋转装置，沿所述外侧换热器1的冷媒流向、且相向设置于所述外侧换热器1的两侧。

可选地，所述旋转装置，可以包括：支撑轴4。
其中，所述支撑轴4，沿所述外侧换热器1的冷媒流向、且固定设置于所述外侧换热器1的一侧。
例如：外侧换热器1的两端各设置有一个支撑轴4，支撑轴4横向设置并与外侧换热器一体连接固定。
由此，通过在外侧换热器的端部固定设置支撑轴，可以使得外侧换热器随支撑轴的旋转更加可靠、也更加稳定。

其中，两个所述支撑轴4的轴心所在的同一条轴线，可以包括：所述外侧换热器1沿冷媒流向的中心线。

更可选地，当所述旋转装置的数量为两个时，两个所述旋转装置中的两个所述轴承3，沿所述外侧换热器1的冷媒流向相向设置。
例如：在外侧换热器1两端部的车架上设置有一对相向布置的轴承3，轴承3固定在汽车车架上。轴承3通过与外侧换热器1两侧设置的支撑轴4配合，实现对外侧换热器1进行支撑和固定。
例如：驱动电机2与外侧换热器1一侧的支撑轴4连接，通过驱动电机2运行，驱动外侧换热器1绕支撑轴4进行旋转，可以使外侧换热器1处于倾斜位置或者横向平放位置。
由此，通过与支撑轴配合设置轴承，可以使外侧换热器随支撑轴的旋转更加可靠、更加安全。
在一个可选实施方式中，还可以包括：驱动装置。
在一个可选例子中，所述驱动装置，可以用于驱动所述旋转装置。
由此，通过驱动装置对旋转装置进行驱动，使得旋转更加方便、更加可控，结构简单，且节省人力。
在一个可选例子中，当所述旋转装置的数量为两个时，所述驱动装置，设置于一个所述旋转装置远离所述外侧换热器1的一侧。
由此，通过只为一个旋转装置设置驱动电机，一方面保证了对旋转装置驱动的可靠性和同步性，便于控制；另一方面可以节省一个驱动电机，节能效果好。
可选地，所述驱动装置，可以包括：驱动电机2。
其中，当所述旋转装置可以包括支撑轴4时，所述驱动电机2，与所述支撑轴4配合设置。
例如：热泵空调在进入化霜模式后，程序控制驱动电机将外侧平行流换热器旋转至倾斜或者横向平放位置，将外侧换热器表面霜层融化后形成的化霜水可自行及时排出，不会重新凝结成冰霜，确保热泵空调正常制热运行。
例如：当热泵汽车空调进入制热模式后，程序控制驱动电机2带动外侧换热器1旋转至倾斜位置。
由此，通过驱动电机驱动旋转装置，驱动方式简便，且可靠性高。
在一个可选实施方式中，还可以包括：柔性连通装置。
在一个可选例子中，所述柔性连通装置，可以用于连通所述外侧换热器1的换热管路与所述待控空调的其它部分。
其中，当所述待控空调可以包括热泵汽车空调时，所述柔性连通装置，可以用于连通所述外侧换热器1的换热管路与所述热泵汽车空调的其它部分。

在一个可选例子中，所述柔性连通装置的数量为两个。两个所述柔性连通装置，且分别与所述外侧换热器1的换热管路的进口管接头和出口管接头连通。
其中，所述进口管接头与所述出口管接头，沿所述外侧换热器1的冷媒流向同时设置于所述外侧换热器1的一侧，或沿所述外侧换热器1的冷媒流向分别设置于所述外侧换热器1的两侧。
例如：外侧换热器1上设置有两个外侧换热器管接头1a，两个管接头分别位于外侧换热器1同侧的上下部位置。
例如：当制冷模式或除霜模式运行时，上端管接头为外侧换热器1的进口，下端管接头为外侧换热器1的出口；当制热模式运行时，上端管接头为外侧换热器1的出口，下端管接头为外侧换热器1的进口。
由此，通过设置两个柔性连通装置，分别与外侧换热器的进口和出口连通，使得外侧换热器的旋转更加灵活、更加方便，且不会影响外侧换热器以及热泵汽车空调的其它部分，可靠性高。
可选地，所述柔性连通装置，可以包括：橡胶软管5。
例如：将外侧平行流换热器设置成可以绕支撑轴进行旋转活动，由电机驱动，平行流换热器的进管和出管接头都与橡胶软管进行连接，通过将外侧平行流换热器自由旋转至倾斜或者横向位置，从而可借助重力作用以及换热器表面的空气流动影响，使外侧平行流换热器表面凝结的冷凝水和除霜水及时自行排出。
例如：为了便于换热器旋转，故采用软管(例如：橡胶软管5)连接。如 图3所示为热泵汽车空调用外侧换热器装置的结构示意图，外侧换热器装置由外侧换热器1、驱动电机2、轴承3、支撑轴4和橡胶软管5组成。
例如：两个外侧换热器管接头1a都与橡胶软管5连接，外侧换热器1通过橡胶软管5再与热泵汽车空调其它系统零部件连接，组成冷媒循环系统。
由此，通过采用橡胶软管连通外侧换热器的换热管路与热泵汽车空调的其它部分，便于旋转，且安全、可靠。
更可选地，所述橡胶软管5的长度，在使所述外侧换热器1处于竖立位置的设定长度基础上，留有设定裕量。
例如：橡胶软管5的长度设置有一定的裕量，橡胶软管5可以进行自由弯曲伸缩，当驱动电机2驱动外侧换热器1旋转时，橡胶软管5不会对外侧换热器1的旋转造成影响。
由此，通过将橡胶软管的长度留有裕量，可以使外侧换热器旋转更加自由、更加灵活，且不会对外侧换热器和热泵汽车空调的其它部分造成影响，使外侧换热器的旋转可靠性得以保障。

在一个可选实施方式中，所述外侧换热器1，可以包括：两个以上的外侧子换热器。
其中，两个以上的所述外侧子换热器，并行设置，且分别能独立实现所述外侧换热器1的功能。
在一个可选例子中，两个以上的所述外侧子换热器中的至少一个所述外侧子换热器，与所述旋转装置配合设置，可以用于在所述旋转装置的带动下进行所述旋转。
在一个可选例子中，两个以上的所述外侧子换热器中的至少另一个所述外侧子换热器，固定设置，可以用于进行所述正常换热。
由此，通过将外侧换热器分成几部分设置，可以节省旋转空间，并提升旋转的灵活性和便捷性。
可选地，两部分以上的所述外侧子换热器，可以包括：外侧上部换热器12和外侧下部换热器11。
在一个可选具体例子中，所述外侧上部换热器12和所述外侧下部换热器11，分别与所述旋转装置配合设置、且能在各自的所述旋转装置的带动下独立地进行所述旋转。
例如：参见图7所示的例子，还可以将外侧平行流换热器设置为分开的上下两部分，两部分换热器绕各自支撑轴进行旋转，由于每个换热器的尺寸变小，当驱动电机带动换热器进行旋转至横向平放位置时，其所需空间也减小，结构更紧凑。
例如：若分为两部分，则旋转成水平方向后，换热器在水平方向占用的空间将变为整个换热器高度尺寸的一半。
其中，当该换热控制装置还可以包括驱动装置、且所述驱动装置可以包括驱动电机2时，所述驱动电机2，可以包括：上部驱动电机22和下部驱动电机21。所述上部驱动电机22，与所述外侧上部换热器12配合设置的所述旋转装置配合设置。所述下部驱动电机21，与所述外侧下部换热器11配合设置的所述旋转装置配合设置。
例如：如图7所示，本替代实施例与最优实施方式的区别为：将外侧换热器1分为外侧上部换热器12和外侧下部换热器11，两部分换热器分别设置有上部驱动电机22和下部驱动电机21，同时还分别设置有支撑轴、轴承等零部 件。两部分换热器可以分别独立的绕其支撑轴进行旋转。其中，由于换热器分为上下两部，换热器在竖直方向的尺寸变小，在旋转至水平横放位置时，所占用的横向空间小，结构更紧凑。
由此，通过将外侧换热器分开设置并各自独立旋转，可以节省旋转过程中占用的空间，且旋转灵活性可以得以提升。
或者，所述外侧上部换热器12固定设置，所述外侧下部换热器11与所述旋转装置配合设置、且能在自身的所述旋转装置的带动下进行所述旋转。
其中，当该换热控制装置还可以包括驱动装置、且所述驱动装置可以包括驱动电机2时，所述驱动电机2，可以包括：下部驱动电机21。所述下部驱动电机21，与所述外侧下部换热器11配合设置的所述旋转装置配合设置。
例如：参见图8所示的例子，将外侧平行流换热器设置为分开的上下两部分，其中上部分换热器保持固定的竖立状态，下部分换热器设置成可以绕其支撑轴进行旋转，其旋转所需空间减小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
例如：如图8所示，本替代实施例与第一替代实施例的区别为：外侧上部换热器12处于固定不旋转状态，外侧下部换热器11上设置有下部驱动电机21、支撑轴、轴承等零部件，外侧下部换热器11可以绕其支撑轴进行旋转。其中，外侧换热器1在制热时，作为蒸发器进行蒸发吸热，此时上端管接头为外侧换热器1的出口，下端管接头为外侧换热器1的进口。由于冷媒由下往上流动，外侧换热器的下半部分更容易形成冷凝水和结霜，因此将外侧换热器分成两部分后，冷凝水和结霜最先从外侧下部换热器11形成，且主要聚集在外侧下部换热器11。在制热模式或者除霜模式下只需控制外侧下部换热器11旋转至倾斜位置或者横向平放位置，即可实现将外侧下部换热器上的冷凝水和除霜水排出，实现最优实施方式中所述的相同的功能。而且，本方案所占用的横向空间小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
由此，通过使下部分换热器旋转、上部分换热器固定，可以节省旋转空间，还可以节省旋转成本，使用便捷性好、人性化好。
经大量的试验验证，采用本实施例的技术方案，通过在热泵汽车空调制热运行时，通过控制热泵汽车空调外侧平行流换热器旋转至倾斜位置，可以有效 排出外侧平行流换热器表面凝结的水，减小换热器风阻，提高换热性能。
根据本发明的实施例，还提供了对应于换热控制装置的一种空调。该空调可以包括：以上所述的换热控制装置。
在一个可选实施方式中，本发明的方案，可以将外侧平行流换热器设置成可以绕支撑轴进行旋转活动，由电机驱动，平行流换热器的进管和出管接头都与橡胶软管进行连接，通过将外侧平行流换热器自由旋转至倾斜或者横向位置，从而可借助重力作用以及换热器表面的空气流动影响，使外侧平行流换热器表面凝结的冷凝水和除霜水及时自行排出。
其中，换热器(即外侧换热器1，如平行流换热器)的进出口的连接一般都用铝管固定连接，因为通常外侧换热器都是固定状态，无需采用橡胶软管。这里为了便于换热器旋转，故采用软管(例如：橡胶软管5)连接。
例如：采用的橡胶软管，可以包括：由外至内依次设置的外胶层、纱线层、内胶层和衬层。其中，外胶层，可以采用具有黑色、耐候、耐臭氧、耐油、耐高低温等性能的材料制成，如可以采用EPDM(三元乙丙橡胶)制成。纱线层，可以采用涤纶、PET(聚对苯二甲酸乙二醇酯)等材料制成。内胶层，可以采用具有黑色、抗渗透、耐高低温、耐寒等性能的材料制成，如可以采用EPDM(三元乙丙橡胶)制成。衬层，可以采用具有白色耐热、耐油、抗渗透等性能的材料制成，如可以采用PA(聚酰胺)制成。
在一个可选例子中，由于热泵汽车空调制热运行时，外侧平行流换热器表面凝结的水会聚集在翅片和扁管上，增大换热器的风阻，降低传热性能。为了解决该问题，可以在热泵汽车空调制热运行时，通过控制热泵汽车空调外侧平行流换热器旋转至倾斜位置，可以有效排出外侧平行流换热器表面凝结的水，减小换热器风阻，提高换热性能。
具体地，热泵空调在制热运行时，程序控制驱动电机按一定的周期将外侧平行流换热器旋转至倾斜位置，将外侧换热器表面凝结到一定程度的冷凝水后可及时自行排出，可以减小换热器风阻，提高换热性能；完成冷凝水排出后再将外侧平行流换热器旋转至竖立位置，不影响换热器正常换热。
其中，自行排出的水，在车辆高速运行时，不会对汽车其它部位造成影响。通常汽车空调的外侧换热器在雨天也有可能会有雨水进入，在设计时，换热器 (例如：外侧换热器1)后面及下面的零部件都有防水的。
可选地，由于热泵汽车空调进入除霜模式后，外侧平行流换热器表面的霜融化后形成的除霜水无法及时排出，重新恢复制热模式运行后除霜水会被冷冻凝结成冰，加重外侧换热器的结霜情况，影响热泵空调正常制热运行。为了解决该问题，可以在热泵汽车空调需要进入除霜模式后，控制热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，让外侧平行流换热器表面的霜融化后的除霜水因为重力作用可以及时自行排出，不会重新凝结成冰霜，确保热泵空调正常制热运行。解决了平行流换热器不能作为外侧换热器应用于热泵汽车空调的问题。
进一步地，由于热泵汽车空调进入除霜模式(即化霜模式)后，车前侧的空气流动会带走外侧换热器表面大量用于除霜的热量，导致除霜速度变慢，除霜效果差，甚至出现无法除霜的现象。为了解决该问题，可以在热泵汽车空调进入化霜后，由于热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，换热器在车前侧的空气流动方向上面积变小，流经换热器表面的空气流量相应降低，可以减少流动空气带走换热器表面用于除霜的热量，有效加快除霜速度，提高除霜效果。
具体地，热泵空调在进入化霜模式后，程序控制驱动电机将外侧平行流换热器旋转至倾斜或者横向平放位置，将外侧换热器表面霜层融化后形成的化霜水可自行及时排出，不会重新凝结成冰霜，确保热泵空调正常制热运行；当化霜运行结束后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
其中，外侧平行流换热器的倾斜角度，可以是大于0度、且小于或等于90度的角度范围。
在一个可选例子中，参见图7所示的例子，还可以将外侧平行流换热器设置为分开的上下两部分，两部分换热器绕各自支撑轴进行旋转，由于每个换热器的尺寸变小，当驱动电机带动换热器进行旋转至横向平放位置时，其所需空间也减小，结构更紧凑。
其中，上下两部分换热器，可以分开，也可以不分开。分开设置主要可以节省空间。
例如：如图5和图7对比可知，如果不分为两部分，旋转成水平方向后，换热器在水平方向占用的空间是整个换热器高度尺寸，若分为两部分，则旋转成水平方向后，换热器在水平方向占用的空间将变为整个换热器高度尺寸的一半。
在一个可选例子中，参见图8所示的例子，将外侧平行流换热器设置为分开的上下两部分，其中上部分换热器保持固定的竖立状态，下部分换热器设置成可以绕其支撑轴进行旋转，其旋转所需空间减小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
在一个可选实施方式中，本发明的方案中，一种热泵汽车空调用可旋转外侧换热器装置，主要通过在热泵汽车空调的制热模式或者除霜模式运行时，将外侧换热器进行旋转，至倾斜位置或者横向平放位置，可以加快排出外侧换热器表面的冷凝水和除霜水，有效提高热泵汽车空调的性能、可靠性。
可选地，如图3所示为热泵汽车空调用外侧换热器装置的结构示意图，外侧换热器装置由外侧换热器1、驱动电机2、轴承3、支撑轴4和橡胶软管5组成。
其中，外侧换热器1放置在汽车空调前侧迎风面，外侧换热器1上设置有两个外侧换热器管接头1a，两个管接头分别位于外侧换热器1同侧的上下部位置；两个外侧换热器管接头1a都与橡胶软管5连接，外侧换热器1通过橡胶软管5再与热泵汽车空调其它系统零部件连接，组成冷媒循环系统。当制冷模式或除霜模式运行时，上端管接头为外侧换热器1的进口，下端管接头为外侧换热器1的出口；当制热模式运行时，上端管接头为外侧换热器1的出口，下端管接头为外侧换热器1的进口。
在一个可选具体例子中，外侧换热器1的两端各设置有一个支撑轴4，支撑轴4横向设置并与外侧换热器一体连接固定，两个支撑轴4的轴心在同一条轴线上。
在一个可选具体例子中，在外侧换热器1两端部的车架上设置有一对相向布置的轴承3，轴承3固定在汽车车架上。轴承3通过与外侧换热器1两侧设置的支撑轴4配合，实现对外侧换热器1进行支撑和固定。
在一个可选具体例子中，驱动电机2与外侧换热器1一侧的支撑轴4连接，通过驱动电机2运行，驱动外侧换热器1绕支撑轴4进行旋转，可以使外侧换 热器1处于倾斜位置或者横向平放位置。
在一个可选具体例子中，橡胶软管5的长度设置有一定的裕量，橡胶软管5可以进行自由弯曲伸缩，当驱动电机2驱动外侧换热器1旋转时，橡胶软管5不会对外侧换热器1的旋转造成影响。
在一个可选例子中，外侧换热器装置(即换热控制装置)的动作过程及控制方法如下：
可选地，如图4所示，当热泵汽车空调进入制热模式后，程序控制驱动电机2带动外侧换热器1旋转至倾斜位置，外侧换热器1在竖直位置和倾斜位置之间的夹角为α，其中15°≤α≤90°。例如：α较小时，可以小于或等于23°；α较大时，可以大于23°。
具体地，外侧换热器倾斜时，可以是外侧换热器上部向内(即车尾方向)，换热器下部向外(即车头方向)进行旋转倾斜。
其中，程序控制驱动电机2也可以按一定的周期将外侧换热器1从竖立位置旋转至倾斜位置保持时间T1，T1时间之后再反向旋转为竖立位置，外侧换热器1在竖立位置保持时间T2，T2时间后再旋转为倾斜位置，如此往复旋转运行。外侧换热器1在处于倾斜位置保持时间T1，可以使外侧换热器1上凝结的冷凝水后进行排出；外侧换热器1恢复旋转为竖立位置后，可以提高外侧换热器1表面的空气流量，确保外侧换热器1的换热性能。
可选地，如图5所示，当热泵汽车空调进入除霜模式后，程序控制驱动电机2带动外侧换热器1旋转至横向平放位置。当热泵汽车空调完成除霜后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
其中外侧换热器1在进入除霜模式后也可以处于倾斜位置，外侧换热器1在竖直位置和倾斜位置之间的夹角为α，其中15°≤α≤90°。
可选地，如图6所示，当热泵汽车空调进入制冷模式后，程序控制驱动电机2带动外侧换热器1旋转至竖立位置。
在一个可替代例子中，如图7所示，本替代实施例与最优实施方式的区别为：将外侧换热器1分为外侧上部换热器12和外侧下部换热器11，两部分换热器分别设置有上部驱动电机22和下部驱动电机21，同时还分别设置有支撑轴、轴承等零部件。两部分换热器可以分别独立的绕其支撑轴进行旋转。
其中，由于换热器分为上下两部，换热器在竖直方向的尺寸变小，在旋转至水平横放位置时，所占用的横向空间小，结构更紧凑。
在一个可替代例子中，如图8所示，本替代实施例与第一替代实施例的区别为：外侧上部换热器12处于固定不旋转状态，外侧下部换热器11上设置有下部驱动电机21、支撑轴、轴承等零部件，外侧下部换热器11可以绕其支撑轴进行旋转。
其中，外侧换热器1在制热时，作为蒸发器进行蒸发吸热，此时上端管接头为外侧换热器1的出口，下端管接头为外侧换热器1的进口。由于冷媒由下往上流动，外侧换热器的下半部分更容易形成冷凝水和结霜，因此将外侧换热器分成两部分后，冷凝水和结霜最先从外侧下部换热器11形成，且主要聚集在外侧下部换热器11。在制热模式或者除霜模式下只需控制外侧下部换热器11旋转至倾斜位置或者横向平放位置，即可实现将外侧下部换热器上的冷凝水和除霜水排出，实现最优实施方式中所述的相同的功能。
而且，本方案所占用的横向空间小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
由于本实施例的空调所实现的处理及功能基本相应于前述图3至图8所示的换热控制装置的实施例、原理和实例，故本实施例的描述中未详尽之处，可以参见前述实施例中的相关说明，在此不做赘述。
经大量的试验验证，采用本发明的技术方案，通过在热泵汽车空调需要进入除霜模式后，控制热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，让外侧平行流换热器表面的霜融化后的除霜水因为重力作用可以及时自行排出，不会重新凝结成冰霜，确保热泵空调正常制热运行，解决了平行流换热器不能作为外侧换热器应可以用于热泵汽车空调的问题。
根据本发明的实施例，还提供了对应于空调的一种空调的换热控制方法。该空调的换热控制方法可以包括：按设定的第一定旋转方向，使待控空调的外侧换热器1旋转至倾斜位置，以利用所述外侧换热器1表面凝结的冷凝水和/或除霜水的重力、以及所述外侧换热器1的外部流动空气，使所述外侧换热器1表面凝结的冷凝水和/或化霜水排出。
例如：如图5所示，当热泵汽车空调进入除霜模式后，程序控制驱动电机 2带动外侧换热器1旋转至横向平放位置。
由此，通过旋转装置，将外侧换热器旋转至倾斜或者横向位置，从而可借助重力作用以及换热器表面的空气流动影响，使外侧平行流换热器表面凝结的冷凝水和除霜水及时自行排出，减小外侧换热器风阻，提升换热性能。
在一个可选实施方式中，还可以包括：按与所述第一旋转方向相反的第二旋转方向，使所述外侧换热器1旋转至竖立位置，以加大所述外侧换热器1的外部流动空气的流量，使所述外侧换热器1正常换热。
例如：当热泵汽车空调完成除霜后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
例如：如图6所示，当热泵汽车空调进入制冷模式后，程序控制驱动电机2带动外侧换热器1旋转至竖立位置。
由此，通过使外侧换热器旋转至竖立位置，可以提升外侧换热器表面空气流量，从而进行正常换热，换热效率高。
在一个可选例子中，使待控空调的外侧换热器1旋转至倾斜位置、并使所述外侧换热器1旋转至竖立位置，可以包括：
步骤S110，在所述待控空调进入制热模式或化霜模式后，使所述外侧换热器1旋转至所述倾斜位置。以及，
例如：在热泵汽车空调制热运行时，通过控制热泵汽车空调外侧平行流换热器旋转至倾斜位置，可以有效排出外侧平行流换热器表面凝结的水，减小换热器风阻，提高换热性能。
例如：热泵汽车空调需要进入除霜模式后，控制热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，让外侧平行流换热器表面的霜融化后的除霜水因为重力作用可以及时自行排出，不会重新凝结成冰霜，确保热泵空调正常制热运行。
例如：在热泵汽车空调进入化霜后，由于热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，换热器在车前侧的空气流动方向上面积变小，流经换热器表面的空气流量相应降低，可以减少流动空气带走换热器表面用于除霜的热量，有效加快除霜速度，提高除霜效果。
例如：在热泵汽车空调的制热模式或者除霜模式运行时，将外侧换热器进 行旋转，至倾斜位置或者横向平放位置，可以加快排出外侧换热器表面的冷凝水和除霜水，有效提高热泵汽车空调的性能、可靠性。
例如：外侧换热器1在进入除霜模式后也可以处于倾斜位置，外侧换热器1在竖直位置和倾斜位置之间的夹角为α，其中15°≤α≤90°。
步骤S120，在所述待控空调在所述制热模式下、且所述外侧换热器1表面凝结的冷凝水后排出后，或在所述待控空调在所述化霜模式下、且所述外侧换热器1表面霜层融化后形成的化霜水排出后，或在所述待控空调在所述化霜模式下完成化霜后，再使所述外侧换热器1旋转至所述竖立位置。
例如：完成冷凝水排出后再将外侧平行流换热器旋转至竖立位置，不影响换热器正常换热。
例如：当化霜运行结束后，驱动电机将外侧平行流换热器旋转至竖立位置，然后热泵汽车空调再切换为正常的制热模式运行，可以有效利用车前侧的空气流动将除霜水排出干净。
由此，通过根据空调所处模式使外侧换热器旋转至倾斜位置或竖立位置，可以使相应模式下外侧换热器表面的阻力减小、换热性能和运行性能都得以提升，有利于提升空调运行的节能性和可靠性。
或者，所述旋转装置使待控空调的外侧换热器1旋转至倾斜位置、并使所述外侧换热器1旋转至竖立位置，还可以包括：

步骤S230，所述第二设定时长到达后，再使所述外侧换热器1旋转至所述倾斜位置并保持所述第一设定时长。
例如：热泵空调在制热运行时，程序控制驱动电机按一定的周期将外侧平行流换热器旋转至倾斜位置，将外侧换热器表面凝结到一定程度的冷凝水后可及时自行排出，可以减小换热器风阻，提高换热性能。
例如：程序控制驱动电机2也可以按一定的周期将外侧换热器1从竖立位置旋转至倾斜位置保持时间T1，T1时间之后再反向旋转为竖立位置，外侧换热器1在竖立位置保持时间T2，T2时间后再旋转为倾斜位置，如此往复旋转 运行。外侧换热器1在处于倾斜位置保持时间T1，可以使外侧换热器1上凝结的冷凝水后进行排出；外侧换热器1恢复旋转为竖立位置后，可以提高外侧换热器1表面的空气流量，确保外侧换热器1的换热性能。
由此，通过定期使外侧换热器旋转至倾斜位置或竖立位置，可以定期排水，有利于提升空调运行的可靠性和换热效果。
在一个可选实施方式中，还可以包括：当所述外侧换热器1可以包括两个以上的外侧子换热器时，使两个以上的所述外侧子换热器中的至少一个所述外侧子换热器，进行所述旋转。
例如：参见图7所示的例子，还可以将外侧平行流换热器设置为分开的上下两部分，两部分换热器绕各自支撑轴进行旋转，由于每个换热器的尺寸变小，当驱动电机带动换热器进行旋转至横向平放位置时，其所需空间也减小，结构更紧凑。
例如：若分为两部分，则旋转成水平方向后，换热器在水平方向占用的空间将变为整个换热器高度尺寸的一半。
例如：如图7所示，本替代实施例与最优实施方式的区别为：将外侧换热器1分为外侧上部换热器12和外侧下部换热器11，两部分换热器分别设置有上部驱动电机22和下部驱动电机21，同时还分别设置有支撑轴、轴承等零部件。两部分换热器可以分别独立的绕其支撑轴进行旋转。其中，由于换热器分为上下两部，换热器在竖直方向的尺寸变小，在旋转至水平横放位置时，所占用的横向空间小，结构更紧凑。
由此，通过将外侧换热器分开设置并各自独立旋转，可以节省旋转过程中占用的空间，且旋转灵活性可以得以提升。
在一个可选实施方式中，还可以包括：当所述外侧换热器1可以包括两个以上的外侧子换热器时，和/或，使两个以上的所述外侧子换热器中的至少另一个所述外侧子换热器，进行所述正常换热。
例如：参见图8所示的例子，将外侧平行流换热器设置为分开的上下两部分，其中上部分换热器保持固定的竖立状态，下部分换热器设置成可以绕其支撑轴进行旋转，其旋转所需空间减小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
例如：如图8所示，本替代实施例与第一替代实施例的区别为：外侧上部 换热器12处于固定不旋转状态，外侧下部换热器11上设置有下部驱动电机21、支撑轴、轴承等零部件，外侧下部换热器11可以绕其支撑轴进行旋转。其中，外侧换热器1在制热时，作为蒸发器进行蒸发吸热，此时上端管接头为外侧换热器1的出口，下端管接头为外侧换热器1的进口。由于冷媒由下往上流动，外侧换热器的下半部分更容易形成冷凝水和结霜，因此将外侧换热器分成两部分后，冷凝水和结霜最先从外侧下部换热器11形成，且主要聚集在外侧下部换热器11。在制热模式或者除霜模式下只需控制外侧下部换热器11旋转至倾斜位置或者横向平放位置，即可实现将外侧下部换热器上的冷凝水和除霜水排出，实现最优实施方式中所述的相同的功能。而且，本方案所占用的横向空间小，结构更紧凑，同时取消了上部分换热器的支撑轴，轴承以及驱动电机等，结构更简单，成本更低。
由此，通过使下部分换热器旋转、上部分换热器固定，可以节省旋转空间，还可以节省旋转成本，使用便捷性好、人性化好。
由于本实施例的换热控制方法所实现的处理及功能基本相应于前述空调的实施例、原理和实例，故本实施例的描述中未详尽之处，可以参见前述实施例中的相关说明，在此不做赘述。
经大量的试验验证，采用本发明的技术方案，通过在热泵汽车空调进入化霜后，由于热泵汽车空调外侧平行流换热器旋转至倾斜位置或横向平放位置，换热器在车前侧的空气流动方向上面积变小，流经换热器表面的空气流量相应降低，可以减少流动空气带走换热器表面用于除霜的热量，有效加快除霜速度，提高除霜效果。
综上，本领域技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上所述仅为本发明的实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
