如图1所示，本申请实施例提供了一种导风圈1，可用于空调器室外机。导风圈1设置成包括导风圈本体11，导风圈本体11整体设置呈环形，且内部形成有导风通道10，导风通道10具有进风口和出风口。导风圈1可与风机配合，风机的风叶可伸入导风圈1的导风通道10内，以便在风机工作时，气流可自进风口进入，并流经该导风通道10，最终自出风口排出。气流的流动方向如图1中的箭头所示，下侧为导风通道10的进风口，上侧为导风通道10的出风口。
如图1-图4所示，导风圈本体11设有两个限位部，分别为：第一限位部12和第二限位部13，两个限位部均可与固定件2配合进行限位，如：第一限位部12可与空调器室外机的固定件2的第一限位配合部211配合限位，以防止导风圈本体11发生径向向外的扩张变形；第二限位部13可与固定件2的第二限位配合部212配合限位，以防止导风圈本体11发生径向向内的收缩变形。即两个限位部配合可对导风圈本体11进行双向限位，能限制导风圈本体11发生径向向外的扩张变形和径向向内的收缩变形。
由于导风圈本体11整体呈环形，因此导风圈本体11的部分径向向外扩张变形时，会导致导风圈本体11的其他部分径向向内收缩变形，或者导风圈本体11的部分径向向内收缩变形时，会导致导风圈本体11的其他部分径向向外扩张变形。通过第一限位部12和第二限位部13限制导风圈本体11发生收缩和扩张变形，有利于减小导风圈1受力后的变形量，维持导风圈本体11的形状稳定性，以便在空调器运行时，导风圈1与风叶之间能够维持安装间隙，避免间隙过小导致的二者相互触碰甚至损坏风叶，以及间隙过大导致的出风量降低，提高了空调器的性能。
相较于普通的导风圈，安装时易于发生变形，从而影响风轮与导风圈之 间的配合，造成风轮叶顶泄露损失增加，导致风机系统性能恶化，本申请实施例的导风圈1，通过设置第一限位部12和第二限位部13，避免了导风圈1发生变形，确保了风轮与导风圈1之间的配合，减小了风轮叶顶泄露的损失，确保了风机系统的性能，从而避免风机系统失效。
一些示例性实施例中，如图1-图4所示，第二限位部13设置成位于第一限位部12的径向外侧(即远离导风圈本体11的中心的一侧)，且第二限位部13和第一限位部12之间设有径向间隔，第二限位部13和第一限位部12可夹在固定件2的两侧。
其中，第一限位部12的外侧壁面(即远离导风圈本体11的中心的一侧的侧壁面)可形成第一限位面123，第二限位部13的内侧壁面(即靠近导风圈本体11的中心的一侧的侧壁面)可形成第二限位面131，第一限位面123和第二限位面131可相互平行。第二限位面131位于第一限位面123的径向外侧，且二者之间设有径向间隔，固定件2插入第二限位部13和第一限位部12之间后，固定件2的第一限位配合部211可与第一限位面123相抵进行限位，固定件2的第二限位配合部212可与第二限位面131相抵进行限位，以防止导风圈本体11发生径向向外的扩张变形和径向向内的收缩变形，进而减小导风圈1受力后的变形量。
一些示例性实施例中，如图1所示，第二限位部13和第一限位部12设置成沿导风圈本体11的周向错位设置，即第二限位部13和第一限位部12位于导风圈本体11的不同周向位置。
当然，第二限位部13和第一限位部12也可以沿导风圈本体11的周向对位设置，即第二限位部13和第一限位部12可位于导风圈本体11的相同的周向位置。
一些示例性实施例中，如图1所示，两个限位部设置成沿导风圈本体11的周向错位设置，其中第一限位部12设置成包括两个子限位部，分别为：第一子限位部121和第二子限位部122，且第二限位部13设置成位于两个子限位部之间，即第二子限位部122、第二限位部13和第一子限位部121设置成沿导风圈本体11的周向依次排布。
固定件2插入第一限位部12和第二限位部13之间的径向间隔内后，固 定件2的第一限位配合部211的两端可分别与两个子限位部相抵限位，固定件2的第二限位配合部212可与位于中间的第二限位部13相抵限位，便于实现导风圈1与固定件2的限位配合。
一些示例性实施例中，如图1所示，导风圈本体11的一侧设有缺口14，该缺口14位于靠近进风口的一侧，第一限位部12的两个子限位部分别位于缺口14的两侧。导风圈本体11设有沿轴向朝向缺口14内延伸(即向下延伸)的凸出部1132，该凸出部1132可形成第二限位部13，使得第二限位部13位于第二子限位部122和第一子限位部121之间，实现了两个限位部之间的错位设置。
此外，缺口14的设置，有利于缩小导风圈1的尺寸，使得在空调器室外机内的有限空间中，导风圈1的尺寸可以最大化，进而使得风轮的尺寸可以最大化，有利于提升风机的性能。
凸出部1132的形状可以为矩形、圆形等，该凸出部1132可与第一限位部12形成嵌入式装配结构，在进行导风圈1安装时，固定件2可以伸入凸出部1132与第一限位部12之间，以有效地定位导风圈1，防止导风圈1安装失位或受力变形。
一些示例性实施例中，如图1所示，凸出部1132(第二限位部13)的侧壁面设有加强筋16。其中，该加强筋16可设置于凸出部1132的外侧壁面(即远离导风圈本体11的中心的一侧的侧壁面)上，或者也可以设置于凸出部1132的内侧壁面(即靠近导风圈本体11的中心的一侧的侧壁面)上，或者，凸出部1132的内侧壁面和外侧壁面上均设有加强筋16。加强筋16设置成可沿导风圈本体11的轴向延伸或者可沿导风圈本体11的周向延伸，或者，加强筋16设置有多个，部分加强筋16可沿导风圈本体11的轴向延伸，部分加强筋16沿导风圈本体11的周向延伸，且轴向延伸的加强筋16和周向延伸的加强筋16之间相互交叉呈网格状。
形成第二限位部13的凸出部1132上设有加强筋16，以增强凸出部1132的强度，进而增强第二限位部13的限位效果，以防止导风圈1受力发生变形。
一些示例性实施例中，第一限位部12设置有多个，且沿导风圈本体11的周向布置，如可均匀布置；第二限位部13也设置有多个，且沿导风圈本体 11的周向布置，如可均匀布置；第二限位部13和第一限位部12的数量相等，并一一对应配合。
第一限位部12和相对应的第二限位部13可以配合实现对导风圈本体11的向内收缩变形和向外扩张变形的双向限位；多个第一限位部12和相对应的多个第二限位部13配合，可更好地实现对导风圈本体11的变形的限位。
由图1和图4可知，第二限位部13和第一限位部12均设置有两个，其中一个第一限位部12和相对应的第二限位部13位于导风圈本体11的前侧，并可与位于前侧的固定件2配合；另一个第一限位部12和相对应的第二限位部13位于导风圈本体11的后侧，并可与位于后侧的固定件2配合。当然，也可以将两个第一限位部12分别设置于导风圈本体11的左侧和右侧，两个第二限位部13分别设置于导风圈本体11的左侧和右侧。
应当理解，第二限位部13和第一限位部12的设置数量不限于两个，可根据需要进行设置。
一些示例性实施例中，如图1-图3所示，导风圈本体11设有支撑部17，支撑部17设置成沿导风圈本体11的周向延伸。其中，支撑部17可为设置在导风圈本体11的外侧壁面上的支撑筋。支撑筋可设置为一整体式结构，或者支撑部17可包括间隔设置的多个支撑筋。
支撑部17可支撑在固定件2上，以实现导风圈1与固定件2的支撑定位。
第二限位部13和第一限位部12设置成可位于支撑部17的下侧(即靠近导风通道10的进风口的一侧)，这样固定件2自靠近进风口的一侧插入第一限位部12和第二限位部13之间，直至与支撑部17相抵，实现了导风圈本体11与固定件2的限位配合以及支撑配合。
一些示例性实施例中，导风圈本体11的侧壁设有固定部，该固定部可与固定件2进行固定连接。其中，如图1-图3所示，固定部可为螺钉固定孔18，可利用螺钉将导风圈本体11与固定件2固定连接。螺钉固定孔18可设有多个(如两个)，以通过多个螺钉实现导风圈本体11与固定件2地牢固固定。
如图2-图4所示，固定部设置成位于支撑部17的上侧(即靠近导风通道10的出风口的一侧)，固定件2的上部可设有固定凸耳23，以便固定凸 耳23上的螺纹孔与导风圈本体11上的螺钉轴线重合后利用螺钉进行固定。
导风圈1与固定件2之间通过支撑部17进行轴向支撑定位，下部通过第一限位部12和第二限位部13进行径向限位，上侧通过螺钉进行固定，使得导风圈1与固定件2之间的固定牢固。当然，第二限位部13和第一限位部12的位置不限于位于支撑部17的下侧，固定部的位置不限于位于支撑部17的上侧，可根据需要进行调整。
一些示例性实施例中，导风圈本体11上设有限位凸起，该限位凸起可与固定件2上的限位孔配合进行限位。或者，导风圈本体11上设有限位孔，该限位孔可与固定件2上的限位凸起配合进行限位。
导风圈本体11和固定件2上分别设有限位凸起和限位孔，以便通过限位凸起和限位孔配合对导风圈本体11和固定件2进行限位，以便导风圈本体11和固定件2进行固定。
一些示例性实施例中，如图1所示，导风圈本体11设置成可包括连接座111和导风管112，连接座111具有第一导风通道，导风管112设置成可呈空心圆柱形，且导风管112具有第二导风通道。连接座111可设置成呈缩口状，连接座111的第一端(即缩口端，图1中的上端)和导风管112连接，如连接座111和导风管112可一体成型，使得连接座111内的第一导风通道和导风管112内的第二导风通道连接，形成导风通道10。连接座111设置成位于靠近进风口的一侧，使得连接座111的第二端(即扩口端，图1中的下端)形成导风通道10的进风口，以便气流从扩口端进入第一导风通道，然后自缩口端流出并流入第二导风通道。
其中，连接座111可与固定件2固定配合，以实现导风圈1的固定。
一些示例性实施例中，如图1所示，连接座111设置成包括相对设置的两个限位侧壁113，每个限位侧壁113设置成包括第一限位部12和第二限位部13，第一限位部12和第二限位部13沿导风圈本体11的径向方向间隔设置，且沿导风圈本体11的轴线方向至少部分重合，每个限位侧壁113的第一限位部12和第二限位部13之间的径向间隔用于夹设固定件2，以便固定件2与第一限位部12配合限位、以及与第二限位部13配合限位，阻碍导风圈本体11的径向向外扩张变形和径向向内收缩变形。
一些示例性实施例中，如图1所示，限位侧壁113设置成包括本体部分1131和自本体部分1131向外凸出的凸出部1132，其中，限位侧壁113的本体部分1131可形成第一限位部12，凸出部1132可形成第二限位部13，且本体部分1131和凸出部1132之间形成限位切口114，该限位切口114用于卡设固定件2。
其中，凸出部1132可自本体部分1131的中部向外凸出，因此，限位侧壁113两端的本体部分1131形成第一限位部12，限位侧壁113中部的凸出部1132形成第二限位部13。
限位侧壁113的本体部分1131形成的第一限位部12可与固定件2抵接配合，以阻碍导风圈本体11的径向向外扩张变形；凸出部1132形成的第二限位部13可与固定件2抵接配合，以阻碍导风圈本体11的径向向内收缩变形。
如图1所示，除凸出部1132(第二限位部13)外，导风圈本体11的其他部分的外壁面上设有沿导风圈本体11的轴向延伸和/或沿导风圈本体11的周向延伸的加强筋16，轴向延伸的加强筋16和周向延伸的加强筋16之间相互交叉呈网格状。其中，导风圈本体11上的加强筋16可与固定件2的第一限位配合部211抵接限位，以进一步减小导风圈本体11的变形量。
如图6所示，本申请实施例还提供了一种空调器室外机。该空调器室外机设置成包括上述任一实施例的导风圈1。其中，该空调器室外机可为柜机。
应当理解，本申请实施例的导风圈1还可以应用到空调器室外机外的其他产品中。
如图1所示，该空调器室外机设置成还包括固定件2。其中，如图2-图5所示，固定件2设有第一限位配合部211，可与导风圈1的第一限位部12配合限位，阻碍导风圈本体11发生径向向外的扩张变形。固定件2还设有第二限位配合部212，可与导风圈1的第二限位部13配合限位，阻碍导风圈本体11发生径向向内的收缩变形。
通过第一限位部12和第一限位配合部211的配合、以及第二限位部13和第二限位配合部212的配合，可减小导风圈1受力后的变形量，以便在空调器运行时维持导风圈1与风叶之间的安装间隙，提高空调器的性能。
一些示例性实施例中，如图2-图5所示，固定件2设置成包括板状主体21，板状主体21具有相对的两板面，以分别形成第一限位配合部211和第二限位配合部212。固定件2与导风圈1装配时，固定件2的板状主体21设置成可夹在(或插入)第一限位部12和第二限位部13之间，以便板状主体21一侧(靠近导风圈本体11的中心的一侧)的板面与第一限位部12的第一限位面123相抵进行限位，板状主体21另一侧(远离导风圈本体11的中心的一侧)的板面与第二限位部13的第二限位面131相抵进行限位。其中，板状主体21一侧的板面与第一限位面123之间可直接接触，且二者之间可为面接触；板状主体21另一侧的板面与第二限位面131之间可直接接触，且二者之间可为面接触。面接触增大了固定件2与导风圈本体11的接触面积，增强了对导风圈本体11的限位效果。当然，板状主体21一侧的板面与第一限位面之间、板状主体21另一侧的板面与第二限位面之间可为线接触。
一些示例性实施例中，如图2-图5所示，固定件2设置成还包括板状主体21的一端(上端)弯折形成的弯折边22，该弯折边22设置成朝向导风圈1的中心所在的一侧弯折，且弯折边22与板状主体21之间的夹角可为约90度，并可用于支撑导风圈1。其中，导风圈1的支撑部17设置成可支撑在该弯折边22上，以实现导风圈1与固定件2的支撑定位。
其中，弯折边22上设有避让凹部221，一方面可进行避让，另一方面便于弯折边22的弯折成型。
一些示例性实施例中，如图2-图5所示，固定件2设置成还包括弯折边22弯折形成的固定凸耳23，该固定凸耳23设置成可向远离板状主体21的一侧(即上侧)弯折，且固定凸耳23与弯折边22之间的夹角可为约90度。
固定凸耳23可用于与导风圈1进行固定，且固定凸耳23上可设有螺纹孔。固定时，固定凸耳23可自进风口所在的一侧伸入导风圈本体11内，螺钉穿过导风圈本体11上的螺钉固定孔18后可与固定凸耳23上的螺纹孔螺接，以实现导风圈1与固定件2的固定连接。
固定凸耳23可设置有多个(如两个)，以通过多个螺钉将导风圈1与固定件2进行牢固固定。
一些示例性实施例中，导风圈1为塑料件，固定件2为钣金件，固定件 2具有较强的结构强度，不易发生变形，因此可利用固定件2对导风圈1进行限位，防止导风圈1发生变形。
当然，导风圈1和固定件2的材质不限于上述，可以根据实际需要进行调整。
一些示例性实施例中，固定件2设置为用于固定电机的电机横梁，即电机横梁既可以用于固定电机，还可以用于固定导风圈1，具有双重功能。
选用固定电机的电机横梁作为固定、限位导风圈1的固定件2，有利于减少空调器室外机的零部件数量，简化产品的结构，降低成体。
当然，也可以另外单独设置固定件2，用于固定导风圈1。
一些示例性实施例中，固定件2设置有两个。电机横梁可包括位于前侧的电机前横梁和位于后侧的电机后横梁。两个固定件2可分别为电机前横梁和电机后横梁。电机前横梁和电机后横梁上均设有弯折边22，当电机前横梁和电机后横梁安装到位后，将导风圈1的连接座111放置于弯折边22，并通过限位孔和限位凸起进行定位，此时，导风圈本体11位于电机前横梁和电机后横梁之间，导风圈本体11的前后两个凸出部1132(第二限位部13)分别从前后两侧卡住电机前横梁和电机后横梁，最后通过螺钉将导风圈本体11与电机前横梁固定，以及通过螺钉将导风圈本体11与电机后横梁固定。
相比于一些情况中，导风圈1支撑在电机横梁的弯折边22上，并通过竖向设置的螺钉(沿导风圈1的轴向设置)固定在电机横梁的弯折边22上，本申请实施例中，导风圈1支撑在电机横梁的弯折边22上，且第一限位部12和第二限位部13夹在电机横梁的板状主体21的两侧，并利用横向设置的螺钉将导风圈1与电机横梁的固定凸耳23固定。本申请实施例中，电机横梁能够更好地对导风圈1进行固定以及限位，使得导风圈1固定牢固，且防止导风圈1发生变形。
本申请实施例中，由于增设了第一限位部12和第二限位部13与电机横梁进行限位配合，可抵抗导风圈本体11的变形，改善了固定螺钉处的受力情况，改善了导风圈1的传力方式及力传导路径，减小了导风圈1受力后的变形量，有利于维持导风圈1的结构稳定性，进而维持导风圈1与风叶的安装间隙，使得空调器室外机能够维持高效稳定地运行。
一些示例性实施例中，缺口14设置成靠近空调器室外机的短边。
导风圈1的轴线设置成竖直设置，其进风口可朝向下方，出风口可朝向上方，使得室外机实现下进风、上出风。缺口14的设置有利于减小导风圈1的体积，将缺口14设置成靠近室外机的机壳的短边(如：机壳沿前后方向的边和沿左右方向的边中较短的一个，如沿前后方向的边)，有利于在机壳内的有限空间内尽可能增大导风圈1的尺寸，可以最大限度地发挥风轮的尺寸，从而有益于风机系统的性能，提高风机的进风量并降低工作噪音。
本申请实施例还提供了一种空调器，包括上述任一实施例所述的空调器室外机。
本申请实施例还提供了一种导风圈(或导流圈)100’，如图7-图10所示，包括：沿着气流流动方向依次设置的进口段1’、中间段2’和出口段3’。
导风圈100’可对气流起到导向作用，使气流的流向规整，能够降低气流的能量损失。沿着气流流动方向，导风圈100’的导风圈本体可包括依次设置的进口段1’、中间段2’和出口段3’，其中，气流沿着导风圈100’的轴向流动，因此，进口段1’、中间段2’和出口段3’沿导风圈100’的轴向依次设置，气流可从导风圈100’的进风端101’流入，气流首先流经进口段1’，随后依次经过中间段2’和出口段3’，最终从导风圈100’的出风端102’流出，因此从进口段1’朝向出口段3’的方向即为气体流动方向。
导风圈100’中，进口段1’包括两个依次相连子进口段1’：第一子进口段11’和第二子进口段12’，第一子进口段11’靠近导风圈100’的进风端101’，第二子进口段12’靠近中间段2’，因此，气流流入导风圈100’时首先流经第一子进口段11’，随后流经第二子进口段12’。
如图10所示，第一子进口段11’包括靠近进风端101’的第一入口端和远离进风端101’的第一出口端，第二子进口段12’包括靠近进风端101’的第二入口端和远离进风端101’的第二出口端，且第二子进口段12’的第二入口端与第一子进口段11’的第一出口端圆滑过渡连接。第一子进口段11’的第一出口端和第二子进口段12’的第二入口端圆滑过渡连接，使得第一子进口段11’和第二子进口段12’的内壁面平滑过渡连接，使得气流流动顺畅平稳，以避免气流在流经第一子进口段11’和第二子进口段12’的连接部位时产生紊流， 进而造成气流的能量损耗较大、影响导风圈100’的导流效果以及增大噪音。
如图10所示，第一子进口段11’的内壁面为朝向导风圈100’外侧凹陷的凹曲面，过该凹曲面上的点做凹曲面的切平面，该切平面与第一平面(与导风圈100’的轴线垂直)M0之间具有夹角。其中，沿着气流流动方向，第一子进口段11’的内壁面上的不同点与第一平面M0的夹角逐渐减小。如图10所示，第一子进口段11’的内壁面上设有沿着气流流动方向依次设置的三个点P1、P2、P3，其中，P1位于第一子进口段11’的第一入口端，P3为第一子进口段11’的第一出口端的内壁面和第二子进口段12’的第二入口端的内壁面之间的相交线上的点，P2位于P1和P3之间。该三个点P1、P2、P3处的切平面M1、M2、M3与第一平面M0的夹角分别为α1、α2、α3，且α1＞α2＞α3。
第一子进口段11’构造为沿着气流的流动方向，第一子进口段11’的内壁面上的不同点的切平面与第一平面M0之间的夹角逐渐减小，使得沿着气流流动方向，第一子进口段11’的通风截面积逐渐减小，即第一子进口段11’逐渐收缩，气流流经第一子进口段11’时流速可提升，有利于提升导风圈100’的进风量。
如图10所示，第二子进口段12’的内壁面为朝向导风圈100’外侧凸出的凸曲面，过该凸曲面上的点做凸曲面的切平面，该切平面与第一平面(与导风圈100’的轴线垂直)之间具有夹角。其中，沿着气流流动方向，第二子进口段12’的内壁面上的不同点与第一平面M0的夹角逐渐增大。如图10所示，第二子进口段12’的内壁面上设有沿着气流流动方向依次设置的三个点P3、P4、P5，其中，P3为第一子进口段11’的第一出口端的内壁面和第二子进口段12’的第二入口端的内壁面之间的相交线上的点，P5位于第二子进口段12’的第二出口端，P4位于P3和P5之间。该三个点P3、P4、P5处的切平面M3、M4、M5与第一平面M0的夹角分别为α3、α4、α5，且α3＜α4＜α5。
第二子进口段12’构造为沿着气流的流动方向，第二子进口段12’的内壁面上的不同点的切平面与第一平面M0之间的夹角逐渐增大，使得第二子进口段12’的内壁面形成朝向导风圈100’内侧凸出的凸曲面，且第二子进口段12’的通风截面积可进一步减小，有利于进一步提升气流流速和进风量。
相比于内壁面为圆锥面的子进口段1’，通过设置内壁面为凹曲面的第一子进口段11’和内壁面为凸曲面的第二子进口段12’，使得进口段1’对气流的导向作用较佳，提升进风量，且气流进入进口段1’后会顺着进口段1’的内壁面平稳地流动，而不会碰撞到进口段1’的内壁面后反弹而降低气流的能量、产生紊流、噪音等，气体流动地稳定性较高，并且可有效降低气流流经导风圈100’时产生的噪音。
因此，本申请实施例的导风圈100’，通过设置第一子进口段11’和第二子进口段12’，可增大导风圈100’的进风量，并降低气流流动的噪音。
一些示例性实施例中，如图10所示，第一子进口段11’的内壁面的凹曲面为凹球面，第二子进口段12’的内壁面的凸曲面为凸球面。
应当理解，第一子进口段11’的内壁面的凹曲面、第二子进口段12’的内壁面的凸曲面还可以为球面外的其他形状的曲面。
一些示例性实施例中，如图10所示，第一子进口段11’中，第一入口端的内壁面的切平面与第一平面M0之间的夹角α1为70°-90°，如：α1可为70°、73°、75°、78°、80°、83°、85°、87°、90°等。第一子进口段11’中，第一出口端的内壁面的切平面与第一平面之间的夹角α3为35°-55°，如：α3可为35°、38°、40°、42°、45°、48°、50°、52°、55°等。
第一入口端的内壁面上的点P1处的切平面M1与第一平面M0之间的夹角α1为70°-90°；第一出口端的内壁面上的点P3处的切平面M3与第一平面M0之间的夹角α3为35°-55°；自第一入口端朝向第一出口端的方向，即沿着气流流动方向，第一子进口段11’的内壁面上的不同点的切平面与第一平面之间的夹角在α1和α3之间，如：第一子进口段11’的内壁面上的点P2处的切平面M2与第一平面M0之间的夹角α2在α1和α3之间，即在α1＞α2＞α3。
导风圈100’应用于产品(如空调器室外机)时，因为室外机的结构尺寸限制，所以导风圈100’的第一子进口段11’的第一入口端的内壁面不像圆一样那么规整，因此，第一子进口段11’的第一入口端的内壁面上，沿着导风圈100’的周向设置的多个点处的切平面与第一平面M0之间的夹角可能不相同，如可分别为80°、82°、78°等。但是，沿着气流的流动方向，第一子进口 段11’的内壁面的切平面与第一平面M0之间的夹角的总体变化趋势都是减小，第二子进口段12’的内壁面的切平面与第一平面M0之间的夹角的总体变化趋势都是增大，只是具体从哪个角度开始变化到哪个角度，这个角度是不是固定的，而是在一定范围内变化。
应当理解，夹角α1的取值范围不限于80°-90°，还可以根据实际需要进行调整；夹角α3的取值范围不限于35°-55°，还可以根据实际需要进行调整。
一些示例性实施例中，如图10所示，第二子进口段12’中，第二入口端的内壁面的切平面与第一平面M0之间的夹角等于第一出口端的内壁面的切平面与第一平面M0之间的夹角α3，第二出口端的内壁面的切平面与第一平面M0之间的夹角α5为80°-100°。
由于第二子进口段12’的第二入口端与第一子进口段11’的第一出口端圆滑过渡连接，因此，第二子进口段12’的第二入口端的内壁面的切平面与第一平面之间的夹角等于第一出口端的内壁面的切平面与第一平面之间的夹角，如图？所示，点P3为第一子进口段11’的第一出口端的内壁面和第二子进口段12’的第二入口端的内壁面之间的相交线上的点，过点P3做第一子进口段11’的内壁面的切平面与过点P3做第二子进口段12’的内壁面的切平面重合，均为切平面M3，因此，第二子进口段12’的第二入口端的内壁面的切平面与第一平面之间的夹角等于第一出口端的内壁面的切平面与第一平面之间的夹角，均为α3，夹角α3为35°-55°。
第二出口端的内壁面上的点P5处的切平面M5与第一平面M0之间的夹角α5为80°-100°，如：α5可为80°、83°、85°、88°、90°、93°、95°、97°、100°等。其中，夹角α5为80°-90°时，第二子进口段12’的通风截面积逐渐减小；夹角α5为90°-100°时，第二子进口段12’的通风截面积先逐渐减小后逐渐增大。
自第二子进口段12’的第二入口端朝向第二出口端的方向，即沿着气流流动方向，第二子进口段12’的内壁面上的不同点的切平面与第一平面之间的夹角在α3和α5之间，如：第二子进口段12’的内壁面上的点P4处的切平面M4与第一平面M0之间的夹角α4在α3和α5之间，即在α3＜α4＜α5。
应当理解，夹角α5的取值范围不限于80°-100°，还可以根据实际需要进 行调整。
一些示例性实施例中，如图10所示，导风圈100’的中间段2’的通风截面保持不变。
中间段2’的内壁面可为圆柱面，使得中间段2’的通风截面积保持不变。圆柱面的轴线与导风圈100’的轴线重合，且第二子进口段12’的第二出口端的内壁面上的点P5处的切平面与第一平面之间的夹角α5为90°，以便实现第二子进口段12’的第二出口端的内壁面与中间段2’的内壁面之间的圆滑过渡连接。
一些示例性实施例中，如图10所示，导风圈100’的出口段3’的通风截面积逐渐增大。
沿着气体流动方向，出口段3’的通风截面积逐渐增大，以增大导风圈100’的出风范围，并可降低气流流速，有利于降低噪音。
一些示例性实施例中，出口段3’的内壁面的切平面与垂直于导风圈100’的轴线的第一平面之间的夹角α6为95°-180°。
如图10所示，出口段3’的内壁面上的任一点P6处的切平面M6与第一平面M0之间的夹角α6为95°-180°，如：α6可为95°、100°、110°、120°、130°、140°、150°、160°、170°、180°等。
其中，出口段3’的内壁面可为朝向导风圈100’内侧凸出的凸球面，且沿着气流的流动方向，出口段3’的内壁面的切平面与垂直于导风圈100’的轴线的第一平面之间的夹角逐渐增大，即出口段3’的内壁面上，沿着气流的流动方向依次设置的多个不同点，该多个不同点处的切平面与第一平面M0之间的夹角逐渐增大。
应当理解，夹角α6的取值范围不限于95°-180°，还可以根据实际需要进行调整；出口段3’的内壁面不限于为朝向导风圈100’内侧凸出的凸球面，还可以为圆锥面等。
一些示例性实施例中，沿导风圈100’的轴向，进口段1’的高度H1、中间段2’的高度H2、出口段3’的高度H3之间的关系为：0.5H2≤H1≤1.5H2，0.05H2≤H3≤1.5H2。
如图10所示，沿导风圈100’的轴向，第一子进口段11’的高度为H11，第二子进口段12’的高度为H12，H11可大于、小于或等于H12，进口段1’的高度为H1，且H1＝H11+H12。沿导风圈100’的轴向，中间段2’的高度为H2、出口段3’的高度为H3，H1、H2、H3之间的关系为：0.5H2≤H1≤1.5H2，0.05H2≤H3≤1.5H2。
H1、H2、H3满足上述关系，且结合进口段1’、中间段2’和出口端的内壁面的形状，可使得导风圈100’的导流效果好，气流流动稳定，能有效降低气流在导风圈100’内流动时的能量损失和工作噪音。
进口段1’的高度H1与中间段2’的高度H2之间满足一定关系，出口段3’的高度H3与中间段2’的高度H2之间满足一定关系，因此，在确定中间段2’的高度H2之后，可根据中间段2’的高度H2确定进口段1’的高度H1和出口段3’的高度H3，以实现导风圈100’的轴向高度的设计。
应当理解，H1、H2、H3之间的关系不限于上述，还可以根据实际需要进行调整。
一些示例性实施例中，沿导风圈100’的轴向，中间段2’的高度H2、伸入导风圈100’内的风叶的轴向高度H0之间的关系为：0.3H0≤H2≤1.2H0。
该导风圈100’与风机配合使用时，风机的风叶可伸至导风圈100’的中间段2’，且中间段2’的轴线与风叶的轴线重合。沿导风圈100’的轴向，中间段2’的高度为H2，风叶的轴向高度为H0，H2与H0之间的关系为：0.3H0≤H2≤1.2H0。这样可根据风叶的轴线高度H0确定中间段2’的高度H2，再根据中间段2’的高度H2确定进口段1’的高度H1和出口段3’的高度H3，使得导风圈100’的尺寸与风叶的尺寸匹配，这样风机工作驱动气体流动时，导风圈100’能够实现良好的导流效果。
应当理解，H0、H2之间的关系不限于上述，还可以根据实际需要进行调整。
将本申请实施例的导风圈100’与普通导风圈比较，结果如图11-图12d所示。
如图11所示，图11为本申请实施例的导风圈(改进导风圈)100’与普 通导风圈在同种工况下的风量噪音测试数据及噪音频谱对比图，本申请实施例的导风圈100’与普通导风圈在风量均为14000m 3/h下，本申请实施例的导风圈100’可比普通导风圈降低约4dBA噪音。
如图12a-图12d所示，图12a-图12d分别为导风圈100’四个侧面在频率为20-20000Hz时的噪音频谱恒定百分比带宽(constant percentage bandwidth，CPB)示意图，横坐标为频率，纵坐标为普通导风圈的噪音值减去本申请实施例的导风圈(改进导风圈)100’的噪音值的差值。从图12a-图12d可以看出，在频率为20-20000Hz内，普通导风圈的噪音值减去本申请实施例的导风圈100’的噪音值的差值大部分为正值，即本申请的导风圈100’的噪音值小于普通导风圈的噪音值。由此可见，本申请实施例的导风圈100’的噪音效果明显优于普通导风圈。
通过实验可知，在本申请的导风圈100’与普通导风圈内的风叶同转速的情况下，采用本申请的导风圈100’，通风量增加8％-11％，并且噪音可降低0.8dBA-1.5dBA；在同通风量的情况下，采用本申请实施例的导风圈100’，工作噪音平均降低3dBA-4dBA。
本申请实施例还提供了一种空调器室外机，包括上述任一实施例提供的导风圈100’。
本申请实施例还提供了一种空调器室外机，包括上述的空调器室外机。
