图1为网络设备的一种结构示意图。网络设备内部包括较多的电子器件，上述电子器件在工作过程中会产生热量，为了提高网络设备的使用寿命和使用效果，需要配置散热结构，以使网络设备内的热量散发出去。如图1所示的网络设备中，上述散热结构包括散热风扇1，散热风扇1设置于网络设备的一端。为了向网络设备输送较为稳定和可靠的电源，网络设备配置两个电源输入组件2，该电源输入组件2设置于散热风扇1的轴端部。
图2为现有技术中网络设备的一种散热风扇剖面结构示意图。如图2所示，网络设备包括两个并排设置的散热风扇1。图3为现有技术中网络设备的一种电源输入组件的剖面结构示意图，如图3所示，为了避免电源输入组件2遮挡散热风道，每个电源输入组件2设置一个较大的镂空结构21。各个散热风扇1均与上述镂空结构21相对，以便于形成散热风道，使散热风扇1产生的风能够为网络设备提供足够的散热风。该方案中，每个电源输入组件2的镂空结构21面积较大，则电源输入组件2能够设置器件的空间较小，则电源输入组件2的器件布局受限，难以扩展电源输入组件2的功能，则电源输入组件2的功能较为单一。若扩展电源输入组件2的功能，则需要在电源输入组件2设置数量较多的器件，则需要减小镂空结构21的尺寸，导致网络设备的散热风道受限，散热效果较差。为了解决电源输入组件2的器件的数量以及散热效果之间的矛盾，本申请提供了一种电源输入组件2和网络设备。
如图1所示，本申请实施例中的网络设备包括壳体3，以及安装于壳体3的至少两个散热风扇1，以及电源输入组件2。其中，散热风扇1安装于网络设备的一侧，电源输入组件2设置于散热风扇1的转轴12端部，即电源输入组件2的平面与散热风扇1的扇叶转动形成的平面大致平行。
图4为本申请实施例中网络设备的一种电源输入组件的结构示意图，如图4所示，电源输入组件2包括电路板28和安装于电路板28上的电子器件，以形成具备各个功能的电源输入组件2。具体地，上述电源输入组件2可以包括安装于电路板的外部电源输入连接器22、电源防护电路23、输出合路电路24和电源输出背板连接器25。其中，外部电源输入连接器22用于将外部电源引入的输入接口，从而为网络设备提供供电输入接口；电源防护电路23与上述外部电源输入连接器22电连接，用于保护电路，确保在部分异常情况下不至于引起燃烧等恶劣影响，上述部分异常情况可以包括过压或者过流等；输出合路电路24与上述电源防护电路23电连接，用于对有多个电源输入组件2的网络设备，避免电流倒灌的情况；电源输出背板连接器25与上述输出合路电路24电连接，作为输出电源到网络设备的背板的接口，通过背板给网络设备各个工作部件供电。
图4为本申请实施例中网络设备的一种电源输入组件的剖面结构示意图。如图2和图 4所示，本申请实施例中的网络设备具有至少两个散热风扇1，电源输入组件2具有与上述散热风扇1一一相对的镂空结构21。如图5所示，在垂直于散热风扇1的转轴12方向的投影上，散热风扇1的投影与镂空结构21的投影重叠，镂空结构21作为网络设备的散热风道，散热风扇1产生的风能够穿透镂空结构21。此外，该电源输入组件2具有与任意相邻的两个散热风扇1之间区域相对的第一遮挡区域26，该第一遮挡区域26能够安装电源输入组件2的器件，以扩展电源输入组件2的功能，例如增加防护电路或者合路功能。该方案在保证了网络设备的散热效果的情况下，还能够使电源输入组件2具有较多的面积安装电子器件，以具有较为丰富的功能。
图6和图7为本申请实施例中网络设备的两种侧面结构示意图。如图6和图7所示，在具体设置散热风扇1时，散热风扇的具体设置方式不限。可以使散热风扇1的出风侧朝向网络设备内侧的方向，如图6所示，散热风扇1将外界新风抽进网络设备内部，再从另一侧吹出；或者，还可以使风扇的进风侧朝向网络设备内侧的方向，如图7所示，则散热风扇1将网络设备内部的热风抽出至外界，外界新风从另一侧进入网络设备内部。
图8示出了本申请实施例中网络设备的另一种侧面结构示意图，请参考图6～图8，对于电源输入组件2与散热风扇1的位置关系，本申请也不做具体限制。电源输入组件2可以设置于散热风扇1的进风侧，如图6和图8所示；电源输入组件2也可以设置于散热风扇1的出风侧，如图7所示；电源输入组件2可以设置于散热风扇1朝向外界的一侧，如图6和图8所示；或者，电源输入组件2也可以设置于散热风扇1朝向网络设备内部的一侧，如图8所示。
具体的实施例中，上述镂空结构21的具体形状不做限制。如图5所示，一种具体的实施方式中，镂空结构21为半圆形结构。该实施例中，半圆形镂空结构21与散热风扇1的扇叶11转动形成的有效风道区域较为匹配，有利于在充分利用散热风扇1形成的有效风道的同时，提高电源输入组件2的面积。由于电源输入组件2的面积得到了增加，故可以增加电源输入组件2的电子器件类型和数量，丰富电源输入组件2的功能。在其它的实施例中，上述镂空结构21还可以为半方形镂空结构21或者三角形镂空结构21，该方案中，镂空结构21的边缘为直线边缘有利于布局电子器件。
图9为本申请实施例中网络设备的另一种电源输入组件的剖面结构示意图。如图9所示，为了提高电源输入组件2的电子器件布局面积，可以使电源输入组件2具有与散热风扇1的转轴12相对的第二遮挡区域27。上述第二遮挡区域27可以安装电源输入组件2的器件。散热风扇1形成风道的有效区域为扇叶11区域，而转轴12区域不会产生流动的气流。本申请的电源输入组件2具有与散热风扇1的转轴12相对的第二遮挡区域27，可以充分利用空间，使电源输入组件2具有较大的电子器件安装面积，增加电源输入组件2的电子器件数量。
图10至图12分别为本申请实施例中网络设备的另三种电源输入组件的剖面结构示意图。请参考图9至图12，本申请实施例中，第二遮挡区域27的形状不做限制。具体可以为半圆形区域、三角形区域或者矩形区域。请参考图9，镂空结构21为半环形镂空结构21，第二遮挡区域27为半圆形区域，镂空结构21的外边缘与散热风扇1的扇叶11转动边缘匹配，第二遮挡区域27的形状与散热风扇1的转轴12区域相匹配。因此，本方案可以在使网络设备的有效风道保持在尺寸较大的情况下，还可以使电源输入组件2具有较大的器件安装面积。请参考图10和图11，第二遮挡区域27的形状为三角形。其中，图10所 示实施例中，镂空结构21的外边缘为弧形。图11示出的实施例中，镂空结构21的外边缘为折线形，与第二遮挡区域27的外边缘匹配。请参考图12，第二遮挡区域27的形状为矩形。对于镂空结构21的形状和第二遮挡区域27的形状，可以根据实际产品情况进行选择。
本申请实施例中，网络设备中散热风扇1的数量不做具体限制，以上仅仅以网络设备具有两个散热风扇1作为示例。例如还可以为三个、四个或者更多。图13为本申请实施例中网络设备的另一种散热风扇剖面结构示意图。图14为本申请实施例中网络设备的另一种电源输入组件的剖面结构示意图。如图13所示，网络设备具有三个散热风扇1。对应地，如图14所示，网络设备包括了与上述三个风扇对应的电源输入组件2，该方案中的电源输入组件2具有与上述散热风扇1一一相对的镂空结构21。
图15为本申请实施例中网络设备的一种电源输入组件安装正确的结构示意图。如图15所示，网络设备包括两个电源输入组件2，两个电源输入组件2的排列方向A与散热风扇1的排列方向B垂直，此处指的是大致垂直。如图5所示，上述两个电源输入组件2对称设置，该方案中，可以使两个电源输入组件2完全相同，将其中一个电源输入组件2相对另一个电源输入组件2反转一百八十度，使两个电源输入组件2的镂空结构21匹配，并与散热风扇1的扇叶11相对，形成有效风道。该方案中，可以制作相同的电源输入组件2，有利于实现电源输入组件2的标准化，简化制作工艺，降低制作难度。
由于上述对称设置的两个电源输入组件2的镂空结构21需要与散热风扇1匹配。因此，每个电源输入组件2需要按照设定的角度安装至网络设备的外壳。如图15所示，壳体3包括用于安装上述电源输入组件2的安装滑槽31，该安装滑槽31具有防误装结构32，以使电源输入组件2按照设定位置安装，即能够与散热风扇1匹配。为了实现该方案，电源输入组件2包括与上述防误装结构32适配的配合结构，当电源输入组件2的配合结构与上述防误装结构32配合安装时，表明电源输入组件2安装正确，如图15所示。当电源输入组件2的配合结构与上述防误装结构32出现结构干涉时，则电源输入组件2无法安装至网络设备的壳体3，以避免电源输入组件2装配错误的问题。
具体的实施例中，上述防误装结构32的设置位置和形式不做限制，可以根据需求选择合适的位置设置上述防误装结构32的具体位置和形式。下面举两个具体的实施例。请参考图15，一种具体的实施例中，可以在安装滑槽31沿插入方向的底端设置限位块321，电源输入组件2具有与上述限位块321适配的限位槽322。当安装上述电源输入组件2时，电源输入组件2插入安装滑槽31，只有电源输入组件2安装方向正确，才可以使电源输入组件2的限位槽322与安装滑槽31的限位块321适配，电源输入组件2正常安装。若电源输入组件2安装方向错误，则电源输入组件2无法完全插入上述安装滑槽31，如图16所示。该方案中，操作人员可以在安装错误时，及时调整电源输入组件2，防止电源输入组件2的镂空结构21与散热风扇1错位，导致网络设备散热效果较差。
图17为本申请实施例中网络设备的另一种电源输入组件安装正确的结构示意图。如图17所示，该实施例中，防误装结构32包括位于安装滑槽31沿插入方向的底端的限位凹槽323，具体的，上述限位凹槽323位于垂直于电源输入组件2的插入方向的竖壁33。电源输入组件2包括与上述限位凹槽323适配的限位凸起324，只有当上述限位凸起324插入限位凹槽323内，电源输入组件2才可以完全安装于网络设备的壳体3。
值得说明的是，本申请实施例中提到的适配，指的是在安装完成状态下，两个结构可以匹配设置，相互适配的结构所处的具体位置和尺寸均适配。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
