Description

直通风散热装置及通信设备 技术领域
本发明涉及通信技术领域， 具体涉及一种直通风散热装置及通信设备。 背景技术
通信设备的发热会导致设备性能的下降乃至损坏。为了使通信设备正常工 作，必须解决通信设备的散热问题，保证通信设备所处的温度在允许的范围内。
常用的散热方案有三种， 包括空调、 热交换器和直通风。 其中， 空调和交 换器的能耗高， 体积大， 可靠性差， 可维护性差。 直通风散热是利用室外新风 直接给通信设备散热， 因而设备工作环境较好， 节能效果明显； 另外， 直通风 散热装置体积较小， 符合产品小型化的趋势， 且可靠性高， 可维护性好。
目前， 普通的直通风散热装置如图 1所示， 主要包括滤网 501 , 风扇 502, 迷宫风道 503和控制板 504。 气流在风扇的驱动下， 经过滤网过滤后， 通过迷 宫风道进入通信设备内部， 最后从出风口流出带走热量， 其中， 控制板可用于 控制风扇的转速和故障上报。 上述普通的直通风散热装置， 过滤效率不高， 一 般低于 50%; 维护周期短， 一般 3到 6个月就需要维护一次； 从而使通信设备 的可靠性降低， 且频繁的维护次数使得维护成本较高。
为了提高过滤效率，现有技术中也有使用透气膜代替滤网的。透气膜的过 滤效率较高， 但是透气膜的阻力随着风力加大而增加， 风阻效应明显， 在风沙 较大的地区， 透气膜很快就会被灰尘堵死而需要维护， 导致维护周期很短。
上述现有的直通风散热装置，维护周期短，需要频繁的维护，维护成本高。 发明内容
本发明实施例提供一种直通风散热装置及通信设备。
一种直通风散热装置， 用于通信设备， 包括：
设置在所述通信设备的进风口的进风装置；
所述进风装置包括沿重力方向或与重力方向之间呈锐角的方向设置的进 风通道，所述进风通道具有低于所述通信设备的进风口的开口用以允许气流由 该开口处进入所述进风通道， 所述进风通道内部设置有过滤模块；
所述过滤模块包括基体和草状纤维，所述基体附着在所述进风通道的侧壁 上， 所述草状纤维的根部固定在所述基体上， 所述草状纤维的端部悬置在所述 进风装置的进风通道的内部并沿所述进风通道的横截面的方向横置于所述进 风通道内。
一种通信设备， 包括：
壳体，设置于壳体内部的设备主体， 和设置在壳体外部的如权利要求 1至 6 中任一项所述的直通风散热装置， 所述壳体上开设有进风口和出风口， 所述直 通风散热装置的进风装置设置在所述进风口。
本发明实施例提供的直通风散热装置，其进风通道大致沿重力方向设置且 用以允许气流进入的开口低于通信设备的进风口，进风通道内设置的过滤模块 中的草状纤维悬置在进风通道内部并沿横截面方向横置于进风通道，能够在进 入气流的作用下自由摆动， 从而， 气流从下向上进入进风通道时， 气流中的粉 尘杂物会经过草状纤维的层层阻挡过滤，过滤下的粉尘杂物会因草状纤维的摆 动而自然沉降， 最后从进风通道的开口落下。 从而， 本发明实施实例的直通风 散热装置就具备了自动降尘功能， 可以免维护或者使维护周期更长， 以降低维 护成本。

所说的进风装置 200, 包括一个沿重力方向或与重力方向之间呈锐角的方 向设置的进风通道 210, 进风通道 210具有低于所述通信设备 100的进风口 111 的开口 211用以允许气流由该开口 211处进入所述进风通道 210, 进风通道 210 内部设置有过滤模块 220。 由于开口 211位于进风口 211的下方， 因而外界的气 流通过该开口 211沿着进风通道 210自下向上流动， 经过过滤模块 220过滤后到 达通信设备 100的进风口 111。 其中， 所说的进风通道 210可以是沿重力方向竖 直设置， 即， 与地平面垂直； 也可以是与重力方向倾斜一个角度， 该角度可以 优选在 30度以内。
如图 3所示， 若说的过滤模块 220, 包括基体 221和草状纤维 222, 基体 221 附着在进风通道 210的侧壁上， 草状纤维 222的根部固定在基体 221上， 草状纤 维 222的端部悬置在所述进风装置 200的进风通道 210的内部并沿所述进风通道 210的横截面的方向横置于所述进风通道内 210。 该过滤模块 220类似于人造草 坪， 可以视为将一块人造草坪粘附在进风通道 210的一面侧壁上， 其中草状纤 维 222的端部 4氏达对面的侧壁， 以完全覆盖进风通道 210的整个横截面。
本实施例过滤装置的原理， 类似于水草过滤河水， 基体 221上固定有多束 均匀或者非均勾排布的草状纤维 222,当气流通过多束草状纤维 222形成的草状 纤维丛时， 气流中夹带的各种灰尘杂质就被随风摆动的草状纤维 222阻挡过滤 下来， 并且由于进风通道 210的开口 211在进风口 111的下方， 气流是从下向上 流动的， 所以被阻挡过滤的灰尘杂质就会因草状纤维 222不断的随风摆动而不 断的向下自然沉降， 最终从进风通道 210的开口 211落下。 从而， 本实施例的直 通风散热装置就具备了自动降尘功能， 既不会被灰尘堵塞，也无需人工定期除 尘维护， 可以实现免维护或者使维护周期更长， 以降低维护成本。
并且， 本发明实施例提供的主要由草状纤维组成的过滤装置，是一个立体 结构， 自下向上具有一定的过滤深度， 可以视为立体过滤； 而现有技术中的过 滤网或透气膜等只有薄薄一层， 可以称为面过滤； 本实施例的立体过滤比面过 滤具有更高的过滤效率， 且不会被灰尘堵塞。
另外， 本发明实施例提供的过滤装置， 其结构具有吸声效果， 可以降低噪 声。
下面， 对所说的过滤模块 220做一步的说明。
如图 3所示， 所说的过滤模块 220中： 其基体 221可以是采用网格布或者编 织布或者复合纤维布等各种材料制成，其上有均勾分布或者非均勾分布的多个 编织孔； 若干根草状纤维 222聚成一束，每一束草状纤维 222固定在一个编织孔 中， 可以用胶水将一束草状纤维 222的根部粘结固定在一个编织孔中； 草状纤 维 222可以是利用各种材料例如聚丙烯、 聚氯乙烯或聚酰胺等纤维制成的仿草 叶状纤维，草状纤维 222的长度以不小于进风通道 210的宽度为佳， 以便使草状 纤维 222的根部通过基体 221固定在进风通道 210的一个侧壁时， 草状纤维 222 的端部能够抵达对面的侧壁， 从而遮挡整个进风通道。 该滤模块 220具有大容 尘率、 低阻力系数的特点。
该过滤模块 220可以仅仅包括一块固定有多束草状纤维 222的基体 221 , 只 固定在进风通道 210的一个侧壁；也可以包括多块固定有多束草状纤维 222的基 体 221 , 分别固定在进风通道 210的多个侧壁， 以实现对进风通道 220更好的遮 挡， 进而提高过滤效率。
本实施例中，对过滤模块 220中基体 221和草状纤维 222的材质均不加限制， 对基体 221和草状纤维 222的尺寸也不加限制， 但以能够配合进风通道 220的尺 寸为宜。例如基体 221可以是长度约为 400毫米， 宽度约为 450毫米左右的矩形； 草状纤维 222可以是长度不小于 10毫米，直径不小于 1毫米的柱状或者条状或其 它形状。 一种实施方式中， 草状纤维 222的长度可以是 50毫米， 此时过滤模块 220的厚度略大于 50毫米。
一个实施例中， 为了使过滤模块 220过滤下来的灰尘杂质能够更好的自然 沉降，以延长维护周期，可以对草状纤维 222进行防尘处理（或者叫憎灰处理）， 以使草状纤维 222不粘灰尘。 例如， 可以在草状纤维 222的表面设置一层纳米材 料， 或者草状纤维 222整体以纳米材料制成， 以取得较佳的憎灰效果。
一个实施例中， 如图 2所示， 进风装置 200进一步包括连接通道 230, 该连 接通道 230的一端与进风通道 210连接， 另一端与通信设备 100的进风口 111连 接， 连接通道 230内设置有进气风扇 240。 外界的空气可以在进气风扇 240的作 用下依次通过进风通道 210和连接通道 230流入通信设备 100内部。 该连接通道 230可以是直形通道，也可以是弯曲通道。采用连接通道 230可以使进风装置 200 具有降噪效果。
一个实施例中， 如图 2所示， 为了加快空气流动速度， 提高散热效果， 直 通风散热装置可以进一步包括一个出风装置 300, 该出风装置 300包括： 连接通 信设备 100的出风口 112的出风通道 310,以及设置在所述出风通道 310内部的排 气风扇 320。通信设备 100内部的空气可以在排气风扇 320的作用下更快的排出， 从而更快的带走通信设备 100内部的热量。
上述的进气风扇 240和排气风扇 320可以外接电源供电，也可以使用通信设 备 100内部的电源供电。 可以提供一个包括进气风扇 240和排气风扇 320的控制 按键的控制板 400固定在通信设备的内部或外部， 供管理维护人员操作。
如图 2和图 4所示， 上述的进风装置 200和出风装置 300在通信设备 100上的 装配位置根据其进风口 111和出风口 112的位置决定，可以设置在通信设备的同 一侧， 也可以设置在相对侧， 或者其它方式均可。 其中出风装置 300可以设置 在通信设备 100的内侧， 也可以设置在通信设备 100的外侧。
综上， 本发明实施例提供的直通风散热装置， 采用主要由草状纤维组成的 具有大容尘虑、低阻力系数特征的过滤模块， 配合沿重力方向方向设置且开口 在下端的进风通道， 具有^艮高的过滤效率， 且具有自动降尘的效果， 可以实现 免维护或者使维护周期更长， 以降低维护成本。 其中， 若草状纤维进行了防尘 处理， 则自动降尘的效果会更好。
如图 4所示， 本发明实施例还提供一种通信设备 100, 包括：
壳体 110, 设置于壳体内部的设备主体 120, 和设置在壳体 110外部的如上 一实施例所述的直通风散热装置， 壳体 110上开设有进风口 111和出风口 112, 该直通风散热装置的进风装置 200设置在所述进风口 111。
其中， 所说的通信设备 100具体可以通信机拒。 所说的直通风散热装置与 该通信机拒可以是相互分离的，通过螺丝连接等方式与通信机拒壳体连接为一 体。 所说的直通风散热装置与该通信机拒壳体也可以是一体化结构。
所说的通信设备还可以是户外机拒、 户外机房和户外迷你小机房 ( Mini-shelter )等其它类型的通信设备。
需要说明的是， 本发明实施例的直通风散热装置不仅适用于通信设备，也 可适用于任何需要散热的设备。
以上对本发明实施例所提供的直通风散热装置及通信设备进行了详细介 例的说明只是用于帮助理解本发明的方法及其核心思想，不应理解为对本发明 的限制。
