详述
下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
如图1-图10所示，本公开实施例提供了一种控制阀400，该控制阀400可包括：阀本体1和排液阀2，阀本体1可包括能连通或断开的进液通道101和出液通道102；排液阀2可安装至阀本体1，且可包括能与出液通道102连通或断开的排液进气通道202。
其中，控制阀400处于出液通道102与进液通道101断开、并与排液进气通道202连通的排液状态时，排液进气通道202设置成能供出液通道102下游回流的积液排出，或者，排液进气通道202设置成能自外界进气以便出液通道102下游的积液顺流排出。
该控制阀400中，其阀本体1可安装有排液阀2，阀本体1的进液通道101和出液通道102可连通或断开，排液阀2的排液进气通道202可与出液通道102连通或断开。根据进液通道101和出液通道102的通断情况、排液进气通道202与出液通道102的通断情况，使得控制阀400具有工作状态和排液状态等不同状态。
其中，如图3和图4所示，控制阀400处于工作状态时，出液通道102可根据需要与进液通道101连通或断开，以实现向出液通道102下游供液(如图3所示，液体的流动方向如图3中箭头所示)或停止向出液通道102下游供液；同时，出液通道102可与排液进气通道202断开，以防止排液进气通道202处漏液。
如图5和图6所示，控制阀400处于排液状态时，出液通道102可与进液通道101断开，以停止向出液通道102下游供液；同时，出液通道102可与排液进气通道202连通，以便将出液通道102下游的积液排出。其中，出液通道102下游的积液可回流(如：积液可在重力作用下回流)，并通过出液通道102后自排液进气通道202排出(积液的流动方向如图5和图6中空心箭头所示)；或者，外界空气可自排液进气通道202进入(空气的流动方向如图5和图6中实心箭头所示)，使得出液通道102下游的积液两侧的通道均可与外界连通，以便积液继续向下游(远离出液通道102的一侧)流动排出(如：积液可在重力作用下向远离出液通道102的一侧顺流排出)。
如图11-图12所示，本实施例的带有排液阀2的控制阀400应用于喷淋系统中时，控制阀400的出液通道102可通过喷淋管道300和喷淋装置200的进口连通，使得在喷淋系统进行喷淋工作时，控制阀400可处于工作状态，以便供水依次通过进液通道101、出液通道102和喷淋管道300后进入喷淋装置200的进口，并最终自喷淋装置200的喷口喷出；在喷淋系统不工作时，控制阀400可处于排液状态，使得喷淋管道300中的积水可回流，并通过出液通道102后自排液进气通道202排出，或者，外界空气可自排液进气通道202进入，使得喷淋管道300中的积水可喷淋装置200排出。本实施例的控制阀400应用于喷淋系统时，可将喷淋管道300中的积水排出，避免了由于喷淋管道300中积水结冰、体积膨胀导致的喷淋电磁阀使用寿命低、影响喷淋电磁阀正常使用等问题。
应当理解，本公开实施例的控制阀400，可用于流体通道中，如：可用于液体通道中，以防止液体通道中积液；或者可用于气体通道。
一些示例性实施例中，如图3-图6所示，阀本体1可设有与出液通道102连通的安装腔103，排液阀2可动地安装至安装腔103，使排液进气通道202可在与出液通道102连通(如图5和图6所示)或断开(如图3和图4所示)之间切换。
控制阀400的阀本体1可设有安装腔103，排液阀2的至少部分可安装在该安装腔103内，且排液阀2可在安装腔103内运动，以便排液阀2的排液进气通道202实现与出液通道102的连通或断开，进而便于控制阀400在工作状态和排液状态之间切换。
一些示例性实施例中，如图3-图6所示，排液阀2与安装腔103的腔壁之间可设有第一密封件3，排液进气通道202可位于第一密封件3的远离出液通道102的一侧。如图3和图4所示，排液阀2设置成能向靠近出液通道102的一侧移动至第一位置，并和安装腔103的腔壁配合夹紧第一密封件3，以使排液进气通道202与出液通道102断开；如图5和图6所示，排液阀2设置成能向远离出液通道102的一侧移动至第二位置，使排液阀2和安装腔103的腔壁配合可放松(不夹紧)第一密封件3，以使排液进气通道202与出液通道102连通。
控制阀400中，排液阀2可动地安装在阀本体1的安装腔103内，排液阀2与安装腔103的腔壁之间可设有第一密封件3，且排液阀2的排液进气通道202位于第一密封件3的远离出液通道102的一侧。其中，如图3和图4所示，当排液阀2向靠近出液通道102的一侧移动至第一位置时，排液阀2可与安装腔103的腔壁配合夹紧第一密封件3，此时第一密封件3可将排液阀2与安装腔103的腔壁之间的间隙密封(第一密封件3处于密封状态)，使得排液进气通道202与出液通道102断开；如图5和图6所示，排液阀2反向 朝远离出液通道102的一侧移动至第二位置时，排液阀2可与安装腔103的腔壁配合放松第一密封件3，此时第一密封件3无法将排液阀2与安装腔103的腔壁之间的间隙密封(第一密封件3处于非密封状态)，使得排液进气通道202与出液通道102可通过排液阀2与安装腔103的腔壁之间的间隙连通。
一些示例性实施例中，如图3-图6所示，安装腔103可包括缩口段1031和扩口段1033，缩口段1031可位于扩口段1033的靠近出液通道102一侧，且缩口段1031的通流截面积可小于扩口段1033的通流截面积，缩口段1031的腔壁和排液阀2配合可夹紧或放松第一密封件3。
设置在阀本体1的安装腔103可包括靠近出液通道102的缩口段1031和远离出液通道102的扩口段1033，该缩口段1031的通流截面积可小于扩口段1033的通流截面积，以在缩口段1031和扩口段1033之间形成环形台阶面。缩口段1031的腔壁可和排液阀2配合，以便在排液阀2移动至第一位置时(如图3和图4所示)，排液阀2与缩口段1031的腔壁配合夹紧第一密封件3；并在排液阀2移动至第二位置时(如图5和图6所示)，排液阀2与缩口段1031的腔壁配合放松第一密封件3。
其中，如图3和图4所示，排液阀2移动至第一位置时，排液阀2靠近出液通道102的一端可伸入安装腔103的缩口段1031内，排液阀2的外侧壁面可与缩口段1031的内侧壁面配合夹紧第一密封件3，和/或，排液阀2的外侧壁面可与缩口段1031远离出液通道102一端的端面(即：缩口段1031和扩口段1033之间形成的环形台阶面)配合夹紧第一密封件3，以将排液阀2与安装腔103的腔壁之间的间隙密封；如图5和图6所示，排液阀2移动至第二位置时，第一密封件3与缩口段1031分离，使得排液阀2的外侧壁面无法与缩口段1031的内侧壁面配合夹紧第一密封件3，且排液阀2的外侧壁面无法与缩口段1031远离出液通道102一端的端面(即：缩口段1031和扩口段1033之间形成的环形台阶面)配合夹紧第一密封件3，此时排液阀2与安装腔103的腔壁之间的间隙未密封，排液进气通道202与出液通道102可通过排液阀2与安装腔103的腔壁之间的间隙连通。
一些示例性实施例中，如图3-图6所示，排液阀2与安装腔103可通过螺纹连接，且排液阀2能够旋拧移动至第一位置或第二位置。

一些示例性实施例中，如图3和图5所示，排液阀2伸出安装腔103外的凸出部分的外侧壁面可设有多个锥形台阶207。
排液阀2可包括伸出安装腔103外的凸出部分，该凸出部分的外侧壁面可设有多个锥形台阶207，该多个锥形台阶207可位于拆装部205的远离出液通道102的一侧。锥形台阶207的设置，便于排液阀2与排液软管连接，以便实现积液的排放。
一些示例性实施例中，如图3-图10所示，排液阀2可为一体式结构。或者，排液阀2可以设置成由多个部件组装而成。
一些示例性实施例中，如图3和图5所示，进液通道101的一端和出液通道102的一端可连接，安装腔103的一端与出液通道102的中部(出液通道102的中部指：除出液通道102的两端外的其他部分，并非仅指出液通道102的中间部分)可连接，且安装腔103和进液通道101可位于出液通道102的同一侧。
阀本体1中，出液通道102的一端(进口端)可与进液通道101的一端(出口端)连接，出液通道102的中部可与安装腔103的一端连接，且安装腔103和进液通道101可位于出液通道102的同一侧，使得进液通道101、出液通道102和安装腔103的布置合理，有利于减小阀本体1的体积。
安装腔103和进液通道101可位于出液通道102的同一侧，如：可均位于出液通道102的下侧，使得安装至安装腔103的排液阀2位于出液通道102的下侧，以便出液通道102下游的积液在重力作用下通过排液进气通道202尽可能完全排出，防止积液残留。
一些示例性实施例中，如图3和图5所示，安装腔103的另一端可朝远离出液通道102的一侧延伸。其中，进液通道101和出液通道102的轴线可相垂直，安装腔103与进液通道101的轴线可平行设置。
另一些示例性实施例中，如图13所示，安装腔103可包括一端连接的第一子腔体1034和第二子腔体1035，且第一子腔体1034的另一端可与出液通道102的中部连接，第二子腔体1035的另一端可朝远离进液通道101的一侧延伸。其中，进液通道101和出液通道 102的轴线可相垂直，安装腔103的第一子腔体1034和第二子腔体1035的轴线可相垂直，且第一子腔体1034与进液通道101的轴线可平行设置，第二子腔体1035与出液通道102的轴线可平行设置。
安装腔103的第二子腔体1035可包括缩口段和扩口段，排液阀2可安装至第二子腔体1035，以便排液阀2与第二子腔体1035的缩口段的腔壁配合夹紧或放松第一密封件3。
上述提供了两种安装腔103的结构，可实现从与进液通道101同一侧进行积水排放，或者从与出液通道102同一侧进行积水排放。在实际应用时，可根据需要选择安装腔103的结构，以便排液阀2以及与排液阀2连接的排液软管的装配。
一些示例性实施例中，进液通道101的进口端可设有第一接头。
进液通道101的进口端处可设置有第一接头，第一接头可为快速接头，且可包括进液接头5，如图1、图3和图5所示。第一接头的设置，便于实现进液通道101与供液管道的快速连接装配。
一些示例性实施例中，如图3和图5所示，进液通道101的进口端可设有过滤网6，以对进入控制阀400的液体进行过滤，防止杂质堵塞控制阀400。
一些示例性实施例中，出液通道102的出口端可设有第二接头。
出液通道102的出口端处可设置有第二接头，第二接头可为快速接头，且可包括出液接头401和快接螺母402，如图1-图3和图5所示。第二接头的设置，便于实现出液通道102与喷淋管道300的快速连接装配。
一些示例性实施例中，控制阀400可为电磁阀，阀本体1可为电磁阀本体。如图1-图3和图5所示，电磁阀本体可包括阀座106、电磁阀芯104和电磁线圈105，阀座106内可设有进液通道101、出液通道102和安装腔103，电磁阀芯104和电磁线圈105均可安装至阀座106，电磁阀芯104可在电磁线圈105通电产生的磁场作用下运动，以将进液通道101和出液通道102连通或断开。其中，电磁阀芯104可为常闭式，即：在电磁线圈105不通电的情况下，电磁阀芯104可将进液通道101和出液通道102断开；电磁线圈105通电时，电磁阀芯104可动作并将进液通道101和出液通道102连通。因此，可通过控制电磁线圈105的通断电，来控制进液通道101和出液通道102的通断。
应当理解，控制阀400不限于为电磁阀，如：控制阀400可为机械阀，其阀本体1可为机械阀本体，可通过手动操作机械阀芯来控制进液通道101和出液通道102连通或断开。
一些示例性实施例中，如图1、图3和图5所示，阀本体1还可设有紧固件(如：螺栓7)，以便将阀本体1固定在安装座。
如图11-图12所示，本公开实施例还提供了一种喷淋系统，可包括喷淋装置200、喷淋管道300以及上述任一实施例提供的控制阀400。其中，控制阀400的出液通道102、喷淋管道300和喷淋装置200的进口可依次连通。
当喷淋系统进行喷淋时，控制阀400可处于工作状态，进液通道101可与出液通道102连通，排液进气通道202可与出液通道102断开。进液通道101可与水源接通，水可进入进液通道101，并通过出液通道102、喷淋管道300向喷淋装置200正常给水，以实现喷淋。
当喷淋系统停止喷淋时，进液通道101可与出液通道102断开，此时喷淋管道300内残存的水受大气压力影响无法排出，导致喷淋管道300内积水，此时进行排水操作。将排液进气通道202与出液通道102连通，排液进气通道202和喷淋装置200的喷口均可与 外界连通，使得喷淋管道300两端气压平衡，使得喷淋管道300内的积水可在重力作用下自排液进气通道202排出或自喷淋装置200的喷口排出。
一些示例性实施例中，如图11所示，喷淋装置200的位置可高于控制阀400，控制阀400处于排液状态时，排液进气通道202设置成能供出液通道102下游回流的积液排出；或者，如图12所示，喷淋装置200的位置可低于控制阀400，控制阀400处于排液状态时，排液进气通道202设置成能自外界进气以便出液通道102下游的积液顺流排出。
如图11所示，在喷淋装置200的安装位置高于控制阀400的情况下，控制阀400处于排液状态时，积水可在重力作用下从排液进气通道202排出，空气可从喷淋装置200的喷口吸入；如图12所示，当喷淋装置200的安装位置低于控制阀400时，空气可从排液进气通道202吸入，积水可在重力作用下从喷淋装置200的喷口排出。
综上所述，本公开实施例的喷淋系统进行正常的喷淋工作时，可用工具将排液阀2拧紧，使排液阀2移动至第一位置，此时排液阀2与阀本体1的安装腔103之间通过第一密封件3实现密封，将排液进气通道202与出液通道102断开，防止漏水；给电磁线圈105通电，使进液通道101和出液通道102连通，水源的水可通过过滤网6过滤后进入进液通道101，并自喷淋装置200的喷口喷出。
当喷淋系统停止喷淋工作时，电磁线圈105处于断电状态，使进液通道101和出液通道102断开；并用工具将排液阀2拧松(不需要完全拆卸)，使排液阀2移动至第二位置，此时第一密封件3与安装腔103的缩口段1031分离，使排液进气通道202与出液通道102连通，喷淋管道300内积水的两侧气压平衡，以便积水在重力作用下从喷淋装置200的喷口和控制阀400的排液进气通道202中位置较低的一个排出，并从位置较高的一个吸气。
应当理解，本公开实施例的带有排液阀2的控制阀400，不仅可应用于喷淋系统，还可以应用到其他开放式水路系统(非循环的水路系统)中。
本公开实施例的喷淋系统，不仅可应用于空调器，还可以应用到其他产品中，如换热系统等。
换热系统广泛应用于化工、石油、动力、食品及其它许多工业生产领域中，换热系统在不同的领域和不同的应用场景的作用不同，比如在化工生产中换热系统可作为加热器、冷却器、冷凝器、蒸发器和再沸器等，应用广泛。
换热系统具有多种形式，例如罐式换热系统、壳管式换热系统等。发明人发现，冷凝器是换热系统的重要组成部分，但是在外部环境过热或者过冷的情况下，冷凝器启动保护机制，不能正常工作。可以通过调节冷凝器的温度从而使冷凝器的温度达到能够正常工作的温度。调节冷凝器的温度可采用通过喷淋系统对冷凝器喷洒流体介质，从而实现冷凝器的温度调节。喷淋系统的喷淋装置可包括喷嘴组件，喷嘴组件可包括基座和喷嘴，喷嘴和基座可拆卸连接。喷嘴的周面可形成喷口，喷口用于供从基座内部流向喷嘴的流体介质喷出。喷嘴可设有第一螺纹，基座可设有第二螺纹，第一螺纹和第二螺纹可螺纹配合从而实现喷嘴和基座螺纹连接。但是由于喷口设置在喷嘴的周面，且喷嘴和基座通过第一螺纹和第二螺纹配合实现可拆卸连接，在将喷嘴安装于基座时，喷口的朝向不可控，因此难以实现对冷凝器精准喷射。
基于上述考虑，为了缓解喷嘴的喷口朝向不可控而难以实现对冷凝器精准喷射的问题，本公开实施例提供了一种喷嘴组件，喷嘴组件的基座可设有第一限位部，第一限位部可用于对喷嘴周向限位，以使喷口朝预设方向设置。
第一限位部可对喷嘴周向限位，则喷嘴安装于基座后，喷嘴的喷口可朝向预设方向， 使得喷嘴组件可沿预设方向喷射流体介质，实现准确地控制流体介质从喷嘴喷出的方向，从而提高喷淋准确性。
本公开实施例公开的喷嘴组件可以但是不限于应用于空调系统、热泵系统等换热系统中，有利于实现精准喷淋。
本公开实施例公开的喷嘴组件可以用于对换热系统的某些结构喷射流体介质，喷嘴组件喷射的流体介质可以用于与被喷淋的结构进行热交换，从而调节该被喷淋的结构的温度。喷嘴组件可以是提高被喷淋的结构的温度，或者可以是降低被喷淋的结构的温度。
如图14-图16所示，喷嘴组件100可包括基座10和喷嘴20；喷嘴20的一端可连接于基座10，喷嘴的周面21可形成喷口22，喷口22可用于供从基座10内部流向喷嘴20的流体介质喷出；其中，基座10可设有第一限位部11，第一限位部11可用于对喷嘴20周向限位，以使喷口22朝预设方向设置。
如图15所示，基座10内部可形成第一流道12，第一流道12可用于容纳流体介质，第一流道12内的流体介质能够流向喷嘴20并从喷嘴20的喷口22喷出。在本实施例中，基座10可呈L形结构。基座10可包括相连的第一部分13和第二部分14，从而形成L形的基座10。第一流道12可包括形成于第一部分13内部的第一段131和形成于第二部分14内部的第二段141，第一段131和第二段141可相连形成L形的第一流道12。
基座10可具有第一端面15和第二端面16，第一端面15可为第一部分13背离第二部分14的一端面，第二端面16可为第二部分14背离第一部分13的端面。第一流道12的一端(第一段131背离第二段141的一端)可延伸至基座10的第一端面15，第一流道12的另一端(第二段141背离第一段131的一端)可延伸至基座10的第二端面16。喷嘴20可以在第一端面15所在侧与基座10连接。第二端面16所在侧可以与向第一流道12内提供流体介质的管道(图中未示出)连接。
基座10还可设有安装部17，基座10可以通过安装部17安装于其他结构。安装部17的结构可以是多种，比如：安装部17可以是用于与螺栓配合的螺纹孔，或者，安装部17可以是用于焊接的焊接部等。
喷嘴20可为柱状结构。喷嘴20可以是圆柱结构、四棱柱结构、六棱柱结构等，本公开对此不作限定。喷嘴的周面21是指围设于喷嘴20的轴线设置的面。喷嘴20内部可形成第二流道23，第一流道12和喷口22可通过第二流道23连通，以使第一流道12内的流体介质能够经过第二流道23从喷口22喷出。
第一流道12和第二流道23可以圆形的流道。第一流道12和第二流道23也可以是其他形式的流道，比如矩形的流道、椭圆形流道等。喷口22可以圆孔、方孔、椭圆孔等。
如图17所示，第二流道23的直径为D，喷口22的直径为d，且可满足4≤D/d≤5。在第二流道23不是圆形流道的实施例中，第二流道23的直径D可以是将第二流道23的横截面等效为圆形的横截面后所获得的直径(即第二流道23的等效直径)。在喷口22不是圆形孔的实施例中，喷口22的直径d可以是将喷口22等效为圆形孔后所获得的直径(即喷口22的等效直径)。第二流道23的直径D和喷口22的直径d满足4≤D/d≤5，使得从基座10流进喷嘴20的流体介质从第二流道23到喷口22在经过变径节流后，从喷口22以合理的流速流出，比如喷出速度可为10m/s-20m/s，以使从喷口22流出的流体介质的流速能够使得流体介质能够充分与待温度调节的目标件(如冷凝器)接触并进行热交换，从而高效调节目标件的温度。
在一些实施例中，如图17、图18所示，喷嘴20的侧壁的周面可设有凹陷部24，喷 口22可设置于凹陷部24的槽壁。如图17所示，凹陷部24的横截面可为扇形，角度为α。凹陷部24的设置使得从喷口22喷射出的流体介质能够形成扇形结构，有利于流体介质与待温度调节的目标件充分接触，从而提高温度调节效率。
流体介质可以是水、空气等。比如，在流体介质为水的实施例中，水从喷口22喷出后在凹陷部24的作用下能够形成扇形水幕，以使从喷口22喷出的水能够覆盖待调节温度的目标件更大的面积。
第一限位部11可以是设置于基座10的外表面，或者可以是设置于基座10的内表面，基座10的内表面为第一流道12的壁面。
第一限位部11可对喷嘴20周向限位，则喷嘴20安装于基座10后，喷嘴20的喷口22可朝向预设方向，使得喷嘴组件100沿预设方向喷射流体介质，实现准确地控制流体介质从喷嘴20喷出的方向，从而提高喷淋准确性。
在一些实施例中，喷嘴20可设有第二限位部25，第二限位部25与第一限位部11配合，以对喷嘴20周向限位。
第二限位部25可以是喷嘴20本身结构的一部分，图15、图16示出了第二限位部25是喷嘴20本身结构的一部分的情况。
如图19-图21所示，第二限位部25可以是单独设置于喷嘴20上的结构，图20、图21示出了第二限位部25是单独设置在喷嘴20上的结构的情况。在第二限位部25是单独设置于喷嘴20上的结构的实施例中，第二限位部25和喷嘴20可以是一体成型，比如通过浇筑、注塑、冲压等一体成型工艺形成。或者，在第二限位部25是单独设置于喷嘴20上的结构的实施例中，第二限位部25和喷嘴20可以是分体设置并通过焊接、粘接、螺栓连接等方式连接为整体结构。
第二限位部25和第一限位部11配合对喷嘴20周向限位，能够提高限位的稳定性。
在一些实施例中，第一限位部11和第二限位部25中的一者可为凹槽，另一者可为凸起，第一限位部11和第二限位部25可插接配合。
如图15、图16所示，第一限位部11可为设置于基座10的凹槽，喷嘴20本身结构的一部分可形成为第二限位部25，第二限位部25插设于为凹槽的第一限位部11内。
凸起和凹槽的结构可以有多种，比如：凹槽可为弧形凹槽，凸起可为与凹槽形状匹配的具有弧面的凸起；或者，凹槽可为矩形凹槽，凸起可以是矩形凸起。
如图20、图21所示，第一限位部11可为设置于基座10的凹槽，第二限位部25可为凸设于喷嘴20的外表面的凸起，凸起可插设于凹槽内，从而实现第一限位部11和第二限位部25配合。
在另一些实施例中，如图22-图24，第一限位部11可为凸起，第二限位部25可为凹槽。
第一限位部11和第二限位部25两者分别为凹槽和凸起，两者插接配合，从而实现喷嘴20和基座10定位配合，使得定位配合的方式更加简单，也使得喷嘴组件100的组装更加简单方便，有利于提高装配效率。
第一限位部11的数量可以是一个，或者可以是多个。多个是指两个及两个以上。在第一限位部11的数量为多个的实施例中，多个第一限位部11可沿喷嘴的周向X间隔布置。多个第一限位部11沿喷嘴的周向X可以是均匀间隔布置，或者可以是非均匀间隔布置。在第一限位部11的数量为多个的实施例中，第二限位部25的数量可以是多个，第二 限位部25和第一限位部11可一一对应设置，第二限位部25可与与之对应的第一限位部11配合，多个第二限位部25可分别和多个第一限位部11配合，共同对喷嘴20周向限位。
示例性地，请继续参见图16、图21、图25，基座10可设有两个第一限位部11，两个第一限位部11可沿喷嘴的周向X间隔布置；喷嘴20可设有两个第二限位部25，第一限位部11和第二限位部25可一一对应设置。两个第一限位部11沿喷嘴的周向X间隔布置，则在喷嘴的周向X上的不同位置，两个第一限位部11可分别与两个第二限位部25配合，共同对喷嘴20周向限位，能够提高对喷嘴20周向限位的稳定性。
在基座10设有两个第一限位部11的实施例中，两个第一限位部11可间隔180°布置。
两个第一限位部11间隔180°布置，则在喷嘴20相对基座10转动180°后喷嘴20上的两个第二限位部25依然能够分别与两个第一限位部11配合实现对喷嘴20周向限位，通过在第一限位部11和第二限位部25配合之前将喷嘴20相对基座10转动180°，能够使得喷口22朝向两个相反的方向中的任意一个，能够根据实际需要切换喷口22的朝向，从而使得该喷嘴组件100的应用更加广泛。
请继续参见图15、图16、图20-图21所示，在基座10内部设有第一流道12、第一流道12的一端延伸至基座10的第一端面15的实施例中，喷嘴20的一端可从第一端面15插设于第一流道12；第一限位部11可设置于第一流道12的壁面，第二限位部25可设置于喷嘴20的外表面。
喷嘴20和基座10之间不仅有第一限位部11和第二限位部25进行定位配合，从而使喷嘴20的喷口22朝向预设方向，从而提高喷嘴组件100的准确性，而且喷嘴20的一端插设于基座10的第一流道12内，则喷嘴20和基座10插接配合，使得喷嘴20本身和基座10本身形成定位配合，方便喷嘴20和基座10组装和提高组装效率。
如图21所示，第二限位部25可为设置于喷嘴20的外周面的凸起，第一限位部11可为设置于第一流道12的壁面的凹槽，且沿喷嘴20和基座10的插接方向，凹槽可延伸至第一端面15。
凹槽沿喷嘴20和基座10的插接方向延伸至第一端面15，凹槽能够在第一端面15形成有开口，该开口也是凸起进入凹槽的入口。
因此，凸起设置于喷嘴20的外周面，凹槽设置于基座10的内表面并沿喷嘴20和基座10的插接方向延伸至基座10的第一端面15，方便喷嘴20和基座10插接配合(喷嘴20插设于基座10)的过程中，凸起沿喷嘴20和基座10的插接方向从凹槽位于第一端面15的开口处进入凹槽，从而实现与凹槽插接配合。凹槽与凸起定位配合不仅能将喷嘴20的喷口22限定在预设方向，从而提高喷嘴组件100的喷淋的准确性，还能避免在喷嘴20和基座10插接配合的过程中两者发生相对转动，以使喷嘴20和基座10准确配合，从而提高喷嘴组件100装配精度。
如图21所示，喷嘴20的一端可插设于第一流道12的第一段131内。第一流道12的第一段131的横截面的轮廓可以与喷嘴20插入第一段131的部分的横截面的轮廓匹配，以便于实现喷嘴20和基座10之间的密封，防止漏液。
在第一限位部11为凹槽的情况下，凹槽可设置于第一流道12的第一段131的壁面。沿喷嘴20和基座10的插接方向，凹槽的尺寸可以与第一段131的尺寸相同，或者可以不同。图20中，沿喷嘴20和基座10的插接方向，凹槽的尺寸可小于第一段131的尺寸。沿喷嘴20和基座10的插接方向，凹槽可具有与喷嘴20位于第一流道12内的第三端面 27相对布置的第一槽壁111，第一槽壁111可以用于对喷嘴20起到限位作用，以限制喷嘴20插入第一流道12的深度。
如图20所示，在一些实施例中，喷嘴组件100还可包括连接螺母30，连接螺母30可套设于喷嘴20和基座10的外周，喷嘴20和基座10通过连接螺母30可拆卸连接。通过连接螺母30实现基座10和喷嘴20可拆卸连接，连接方便，连接稳定性好。
连接螺母30可具有内孔31，内孔31的至少部分设有第二内螺纹32。喷嘴20和基座10中的至少一者可设有第二外螺纹18(参见图26)，第二内螺纹32和第二外螺纹18配合。基座10和喷嘴20可以均与连接螺母30螺纹连接，从而将基座10和喷嘴20连接为整体结构。
基座10和喷嘴20中的一者可以与连接螺母30螺纹连接，另一者可以通过其他方式与连接螺母30连接，从而将基座10和喷嘴20连接为整体结构。比如，基座10与连接螺母30可螺纹连接，喷嘴20与连接螺母30可挂扣连接；或者，喷嘴20与连接螺母30可螺纹连接，基座10与连接螺母30可挂扣连接，从而实现将基座10和喷嘴20连接为整体结构。
示例性地，如图15、图18、图20、图23、图24所示，喷嘴20的外周面可凸设有第一凸缘26，第一凸缘26可位于基座10外；连接螺母30可与基座10螺纹连接，连接螺母30的内周面可凸设有第二凸缘33，沿喷嘴20和基座10的插接方向，第二凸缘33可位于第一凸缘26背离基座10的一侧，以限制喷嘴20脱离基座10。
基座10的第一部分13的外周面可设置有第二外螺纹18。
沿喷嘴20的径向，第一凸缘26可从喷嘴20的外周面沿背离喷嘴20的轴线方向延伸，且第一凸缘26可为沿喷嘴的周向X延伸的封闭的环状结构。
沿连接螺母30的轴向，连接螺母30的内孔31的孔壁的一部分设置有第二内螺纹32，连接螺母30的内孔31的孔壁的另一部分未设置有第二内螺纹32，第二凸缘33从连接螺母30的内孔31的孔壁的未设置有第二内螺纹32的部分向靠近连接螺母30的轴线方向凸出于连接螺母30的内孔31的孔壁。第二凸缘33可为沿喷嘴的周向X延伸的封闭的环状结构。第一凸缘26的外直径大于第二凸缘33的内直径，则沿连接螺母30的轴向，第二凸缘33能够在第一凸缘26背离基座10的方向与第一凸缘26相抵，从而对喷嘴20起到限位作用，以降低喷嘴20脱离基座10的风险。
连接螺母30可与基座10螺纹连接，第二凸缘33和第一凸缘26配合以限制喷嘴20脱离基座10，从而实现基座10和喷嘴20通过连接螺母30可拆卸连接，这样能够减小连接螺母30旋转的圈数，提高连接效率和使得喷嘴组件100的组装更加方便。
如图15、图20、图23-图24、图26-图28所示，在一些实施例中，喷嘴组件100还可包括第二密封件40，第二密封件40可密封于喷嘴20和基座10之间。第二密封件40的设置能够提高喷嘴20和基座10之间的密封性能，降低基座10和喷嘴20连接位置处漏液的风险。
第二密封件40的材质可以是合成树脂、金属、植物的纤维、动物的皮革或其他的材料，如陶瓷等。
在喷嘴20插设于第一流道12的实施例中，第二密封件40可以位于第一流道12的壁面和喷嘴20的外周面之间，以在第一流道12的壁面和喷嘴20的外周面之间实现密封。
在喷嘴20的外周面凸设有第一凸缘26的实施例中，沿喷嘴20和基座10的插接方向，第二密封件40可密封于第一凸缘26和第一端面15之间。第二密封件40套设于喷嘴20 能够提高喷嘴20的连接稳定性，还能在喷嘴的周向X上的任意位置起到密封作用，进一步提高喷嘴20和基座10之间的密封性能。
沿喷嘴20和基座10的插接方向，第二密封件40可位于第一凸缘26面向基座10的表面和第一端面15之间，第一凸缘26可位于第二凸缘33和第二密封件40之间。
当连接螺母30与基座10拧紧的过程中，喷嘴20的第一凸缘26在连接螺母30的压力下和基座10的第一端面15共同挤压第二密封件40，第二密封件40可变形以密封喷嘴20与基座10间的间隙，以降低漏液的风险。第一凸缘26和基座10的第一端面15可共同挤压第二密封件40，以使第二密封件40更稳定地密封在喷嘴20和基座10之间。第二密封件40密封于第一凸缘26和基座10的第一端面15之间，还便于第二密封件40的安装。
在第二限位部25为凸设于喷嘴20的外周面的凸起、喷嘴20的外周面凸设有第一凸缘26的实施例中，第二密封件40套设于喷嘴20并位于第一限位部11和第一凸缘26之间。
在第二限位部25为设置于喷嘴20的外周面的凸起、第二密封件40套设于喷嘴20的实施例中，第二密封件40的内直径可大于第二密封件40套设位置处喷嘴20的外直径，第二密封件40的外直径可小于第一凸缘26的外直径。
在喷嘴20插设于第一流道12内、且喷嘴20的外周面凸设有第一凸缘26的实施例中，如图26所示，第一限位部11可以是设置第一端面15的凹槽，第二限位部25可以为设置第一凸缘26面向第一端面15的端面上的凸起，凸起沿喷嘴20和基座10的插接方向延伸，凸起插设于凹槽内。或者，如图27所示，第一限位部11可以是设置第一端面15的凸起，第二限位部25为设置第一凸缘26面向第一端面15的端面的凹槽，凸起沿喷嘴20和基座10的插接方向延伸，凸起插设于凹槽内。
在一些实施例中，喷嘴20可以不插设于第一流道12。如图28所示，喷嘴20的第三端面27可与基座10的第一端面15相对布置。第一限位部11可设置第一端面15，第二限位部25可设置于第三端面27。连接螺母30可套设于基座10和喷嘴20的外周，基座10和喷嘴20可通过连接螺母30可拆卸连接。图28中示出了第一限位部11可为设置于第一端面15的凸起，第二限位部25可为设置于第三端面27的凹槽的情况。或者，第一限位部11可以为设置于第一端面15的凹槽，第二限位部25可以为设置于第三端面27的凸起。
本公开实施例还提供了一种空调器，如图29所示，可包括室外换热器和上述任一实施例提供的喷淋系统，喷淋系统的喷淋装置200设置成能喷淋室外换热器。该室外换热器可作为冷凝器或者蒸发器。
该空调器中，喷淋装置200能向室外换热器喷水或其他液体，以便冲洗室外换热器，避免室外换热器上聚集污物，影响室外换热器的换热效率；此外，喷淋的水或液体蒸发还可吸收室外换热器的热量，增加室外换热器的换热效率。
本公开实施例还提供一种换热系统，如图30所示，换热系统包括冷凝器和上述任意实施例提供的喷淋系统，喷淋系统可用于向冷凝器喷射流体介质。
该喷淋系统可包括喷嘴组件100；喷嘴组件100可用于向冷凝器喷射流体介质，以调节冷凝器的温度。
上述任意实施例提供的喷嘴组件100，通过第一限位部11对喷嘴20周向限位，从而使得喷口22朝向预设方向，使得流体介质的喷射方向沿预设方向，使得流体介质的喷射 方向能够准确地控制，从而提高喷淋准确性，更加有效地对冷凝器进行温度调节。
冷凝器为换热系统的机件，属于换热器的一种，能把气体或蒸气转变成液体，将管子中的热量，以很快的方式，传到管子附近的空气中。冷凝器工作过程是个放热的过程，所以冷凝器温度都是较高的。当冷凝器的温度过高时，冷凝器的保护机制启动，使得冷凝器不能正常工作。喷嘴组件100通过向冷凝器喷淋流体介质能够降低冷凝器的温度，从而使得冷凝器能够正常工作。
当然，不排除在一些特殊情况下，冷凝器需要提升温度才能正常工作，比如环境温度很低的情况下，可以通过喷嘴组件100向冷凝器喷淋流体介质从而提升冷凝器的温度，以使冷凝器能够在较低的环境温度下正常工作。
