具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结 合附图来对本公开实施例提供的风机装置及电子设备进行详细描述。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
图1是根据本公开的实施例的风机装置的结构图，图2是根据本公开的实施例的导叶组件在出气一侧的结构图。
参阅图1和图2，本公开实施例提供一种风机装置，该风机装置包括动叶组件1和位于该动叶组件1的出气口一侧的导叶组件2。动叶组件1包括多个旋转叶片11和用于驱动多个旋转叶片11旋转的驱动机构(图中未示出)。导叶组件2包括第一框体21、多个导向叶片23和多个自动调节结构。如图2所示，多个导向叶片23均位于第一框体21的内侧，且与该第一框体21活动连接。
根据本公开的实施例，如图1所示，动叶组件1还包括第二框体13和设置在该第二框体13内侧的第二轮毂12。第二框体13位于第一框体21的进气口一侧，且与该第一框体21固定连接，并且第一框体21和第二框体13在二者的内侧分别限定形成可供气体流动的通道。多个旋转叶片11环绕设置在第二轮毂12的周围，且与该第二轮毂12连接。上述驱动机构与第二轮毂12连接，用以通过第二轮毂12驱动多个旋转叶片11旋转。该驱动机构例如为旋转电机。在驱动机构的驱动下，多个旋转叶片11旋转产生气流，该气流朝向导叶组件2流动，气流方向为图1中示出的X方向。
在实际应用中，旋转叶片11的数量一般为两个以上。在一些可选的实施例中，两个以上的旋转叶片11在第二轮毂12的圆周方向上均匀分布，这样可以保证与各个旋转叶片11连接的第二轮毂12在其圆周方向上的承重均匀性，从而可以提高结构稳定性。例如，旋转叶 片11的数量为两个、三个、四个、五个、六个等等，以旋转叶片11的数量为六个为例，如图1所示，六个旋转叶片11在第二轮毂12的圆周方向上均匀分布。
在实际应用中，导向叶片23的数量一般为两个以上。在一些可选的实施例中，导向叶片23的数量与旋转叶片11的数量相同，当然，在实际应用中，根据不同的需要，导向叶片23的数量也可以少于或多于旋转叶片11的数量，本公开实施例对此没有特别的限制。
根据本公开的实施例，如图2所示，导叶组件2还包括第一轮毂25，多个导向叶片23环绕设置在该第一轮毂25的周围。
图7是根据本公开的实施例的导向叶片的结构图。如图7所示，每个导向叶片23包括叶片本体231、第一固定杆232和第二固定杆233。第一固定杆232沿第一轮毂25的径向(即，通过第一轮毂25的径向截面的中心的直径方向)设置，且该第一固定杆232的两端分别与叶片本体231和第一轮毂25活动连接，以使叶片本体231能够围绕该第一固定杆232转动。上述第二固定杆233与第一固定杆232同轴设置，且第二固定杆233的两端分别与叶片本体231和第一框体21活动连接。也就是说，第一固定杆232和第二固定杆233可以用作叶片本体231的旋转轴，叶片本体231可以围绕该旋转轴转动，以能够改变叶片本体231(例如吸力面)与第一轮毂25的径向截面之间的夹角(在下文中称为导向叶片的安装角度)。
根据本公开的实施例，继续参照图1和图2，上述第一框体21和第二框体13的内径相同，且上述第一轮毂25与第二轮毂12同轴设置。
各个自动调节结构与各个导向叶片23一一对应地连接，每个自动调节结构用于根据第一框体21的出气口处的风力大小，自动调节对应的导向叶片23的安装角度，即，在自动调节结构的调节作用下，导向叶片23的安装角度能够随第一框体21的出气口处的风力变化而变化。由叶栅速度三角形可知，在旋转叶片11的旋转速度升高时，其周向速度会增加，从而引起导向叶片23的进气角度增加，此时若导向叶片23的安装角度固定不变，则导向叶片23的进气攻角会增加， 导致导向叶片23的吸力面气流分离，这种情况不仅会增加气流损失，降低风机效率，而且还会因旋转叶片11与导向叶片23气流干涉而引起离散噪音增加。为了解决该问题，本公开实施例提供的风机装置，利用上述自动调节结构根据第一框体21的出气口处的风力大小，自动调节对应的导向叶片23的安装角度，可以在旋转叶片11的旋转速度改变时，通过自动调整导向叶片23的安装角度，使导向叶片23的进气攻角始终被调整至最优状态，从而不仅可以保证在全工作段内的旋转叶片11与导向叶片23的气流匹配，减少气流损失，进而提高风机效率，而且可以避免出现导向叶片23的吸力面气流分离的问题，从而可以降低由旋转叶片11与导向叶片23气流干涉而引起的离散噪音，进而提升整机散热性能。
根据本公开的实施例，如图1和图2所示，导叶组件2包括风力罩24，每个自动调节结构包括传动机构22。
图3是根据本公开的实施例的导叶组件的侧视图。如图3所示，风力罩24位于第一框体21的出气口一侧，且与第一框体21活动连接。
图6是根据本公开的实施例的风力罩与第一框体的局部剖视图。如图6所示，风力罩24的一部分自第一框体21的内侧壁向该第一框体21的内侧凸出，以能够在风力作用下沿第一框体21的出气口的轴向(即，图1中的X方向)移动。可选的，风力罩24为环形罩，该环形罩的内径小于第一框体21的内径，以使环形罩的内侧部分能够自第一框体21的内侧壁向其内侧凸出。当然，在实际应用中，风力罩24也可以是其他任意结构，只要能够在风力作用下移动即可。
继续参照图1和图2，上述传动机构22分别与风力罩24和对应的导向叶片23活动连接，用于在风力罩24移动时带动导向叶片23转动，以改变导向叶片23的安装角度。当风力罩24在风力作用下移动时，风力罩24移动产生的动力会经由上述传动机构22转换成旋转动力，并传递至导向叶片23，从而实现导向叶片23的安装角度的自动调整，而且，风力罩24的位移量的大小决定了导向叶片23的安装角度的变化量。
上述传动机构22的结构可以有多种。例如，图4是根据本公开的实施例的导叶组件的局部结构图，图5是根据本公开的实施例的导叶组件局部剖视图，如图3至图5所示，上述传动机构包括第一连杆227、第二连杆223、弹性件221和限位结构。在第一框体21上设置有将该第一框体21的内侧和外侧贯通并且在第一框体21上延伸的限位槽226，第一连杆227穿设于该限位槽226中，且能够沿该限位槽226的延伸方向移动，并且，如图5所示，第一连杆227的一端与导向叶片23连接，第一连杆227的另一端与第二连杆223的一端活动连接，第二连杆223的另一端与风力罩24活动连接。
根据本公开的实施例，如图5所示，第一连杆227的一端位于第一框体21的内侧，并与导向叶片23螺纹连接，另一端由内而外穿过限位槽226，并延伸至第一框体21的外侧，与第二连杆223活动连接，第一连杆227与第二连杆223活动连接的方式例如为铰接。例如，在第二连杆223上设置有安装孔，第一连杆227穿过该安装孔，且能够在安装孔中转动，并且第一连杆227的靠近安装孔的一端设置有限位部，用以避免第二连杆223脱离第一连杆227。当然，在实际应用中，还可以采用其他任意方式实现第一连杆227与第二连杆223的活动连接。
根据本公开的实施例，如图3所示，上述限位结构包括连接件222和两个限位杆224。连接件222位于第一框体21的外侧，且与风力罩24连接，连接方式例如为焊接或者一体成型等等，并且在连接件222上设置有两个导向通孔225。如图4和图5所示，各个限位杆224穿过对应的导向通孔225与第一框体21连接，并且限位杆224能够在风力罩24移动时与对应的导向通孔225相对移动。根据本公开的实施例，如图3所示，上述导向通孔225例如为长孔，且该长孔的长轴方向与图3中的X方向相互平行，限位杆224能够沿该长孔的长轴方向移动，从而可以将风力罩24的移动方向限定在X方向，并且长孔在长轴方向上的长度限定了风力罩24的移动范围。需要说明的是，限位杆224的数量并不局限于本实施例中的两个，在实际应用中，根据具体需要，限位杆224的数量也可以为一个或者三个以上。
上述限位结构设置在第一框体21上，且与风力罩24活动连接，用以限定风力罩24在预设移动范围内沿第一框体21的出气口的轴向(即，图3中的X方向)移动，即，上述限位结构用于限定风力罩24的移动方向和移动范围。根据本公开的实施例，如图3所示，第二连杆223通过该限位结构与风力罩24活动连接，但是，本公开实施例并不局限于此，在实际应用中，也可以使第二连杆223直接与风力罩24活动连接。
根据本公开的实施例，上述限位杆224的一端与第一框体21螺纹连接，另一端设置有限位部，用以防止与连接件222相脱离。
需要说明的是，在本实施例中，连接件222的数量与导向叶片23的数量相同，且一一对应，但是，本公开实施例并不局限于此，在实际应用中，也可以使连接件222采用一体式结构，即，多个连接件222连为一体，例如采用环形结构。
上述弹性件221分别与第一框体21和风力罩24连接，用于向风力罩24施加能够使其复位至初始位置的弹力。上述弹性件221与连接件222连接，以通过连接件222带动风力罩24复位。上述风力罩24的复位方向即与图3中的X方向相反，而风力罩24的初始位置即为与第一框体21的出气口所在端部相接触的位置处。
根据本公开的实施例，如图3所示，弹性件221包括拉伸弹簧，该拉伸弹簧的轴线与第一框体21的出气口的轴向(即，X方向)相互平行。这样设置，可以使拉伸弹簧向风力罩24施加的弹力方向与X方向相互平行，从而保证风力罩24能够顺利复位。
根据本公开的实施例，如图5所示，第一框体21的出气口所在端部设置有自第一框体21的外侧壁向第一框体21的外侧凸出的凸台211，风力罩24在位于上述初始位置时与凸台211相互叠置。在凸台211上设置有沿第一框体21的出气口的轴向(即，X方向)贯通该凸台211的通孔，连接件222穿过该通孔连接从风力罩延伸至限位杆224所在位置处。
根据本公开的实施例，如图3所示，限位槽226的延伸方向呈圆弧状，且限位槽226的一端相对于另一端更靠近第一框体21的出 气口。这样设置，可以对导向叶片23的旋转方向起到导向作用。当然，在实际应用中，限位槽226还可以采用其他任意形状，只要导向叶片23能够转动即可。
图8是根据本公开的实施例的传动机构在风力罩处于两个不同位置处的状态图。参阅图8，在风力罩24没有受到第一框体21的出气口处的风力作用或者风力作用无法驱动风力罩24移动的情况下，风力罩24位于初始位置，即，位于如图8中(a)图所示的位置a1，此时连接件222位于(a)图所示的位置b1，第一连杆227位于限位槽226的远离第一框体21的出气口的一端处，即，位于(a)图所示的位置c1，在这种情况下，导向叶片23的安装角度位于初始角度，该初始角度可以根据具体需要自由设定。在风力罩24受到的风力作用能够驱动风力罩24移动的情况下，风力罩24自上述初始位置沿远离第一框体21的出气口的方向(即，X方向)移动，例如风力罩24的最大位移量对应的位置位于如图8中(b)图所示的位置a2，在此过程中，风力罩24带动连接件222自位置b1相对于限位杆224沿X方向同步移动，直至到达如图8中(b)图所示的位置b2，第一连杆227沿限位槽226逆时针移动(即，沿图8中的Y方向移动)，直至位于限位槽226的靠近第一框体21的出气口的一端处，即，位于(a)图所示的位置c2，在这种情况下，导向叶片23的安装角度自上述初始角度转动一定的角度。由此，实现导向叶片23的安装角度的自动调节。
需要说明的是，在实际应用中，可以通过设计限位槽226在第一框体21上的位置，以及限位槽226的延伸弧长，来设定导向叶片23的安装角度的可调范围，并适应性地调整其他部件的位置和尺寸。
综上所述，本公开实施例提供的风机装置，其通过设置多个自动调节结构，并与多个导向叶片一一对应地连接，每个自动调节结构用于根据第一框体的出气口处的风力大小，自动调节对应的导向叶片的安装角度，可以在旋转叶片的旋转速度改变时通过自动调整导向叶片的安装角度，使导向叶片的进气攻角始终被调整至最优状态，从而不仅可以保证在全工作段内的旋转叶片与导向叶片的气流匹配，减少 气流损失，进而提高风机效率，而且可以避免出现导向叶片的吸力面气流分离的问题，从而可以降低由旋转叶片与导向叶片气流干涉而引起的离散噪音，进而提升整机散热性能。
本公开实施例还提供一种电子设备，其包括本公开实施例提供的上述风机装置。
本公开实施例提供的电子设备例如为承载、固网、无线基带处理单元(BBU)、服务器存储、能源产品等等。
本公开实施例提供的电子设备，其通过采用本公开实施例提供的上述风机装置，不仅可以保证在全工作段内的旋转叶片与导向叶片的气流匹配，减少气流损失，进而提高风机效率，而且可以避免出现导向叶片的吸力面气流分离的问题，从而可以降低由旋转叶片与导向叶片干涉而引起的离散噪音，进而提升整机散热性能。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为在本公开的保护范围内。
