通信设备用散热拒
技术领域
本发明实施例涉及散热技术， 尤其涉及一种通信设备用散热拒。 背景技术
目前， 为了使通信设备中的电子设备免于受外界破坏， 业界通常将这些 通信设备安装在机拒中。 而随着通信设备的功率的不断增加， 通信设备在工 作过程中产生的热量也不断增加 , 这样如何为安装在机拒中的通信设备散热 就成为亟需解决的一个问题。

为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面 描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。

图 3为根据本发明实施例三的具有翅片的通信设备用散热拒的结构示意 图；
图 4为根据本发明实施例四的通信设备用散热拒的结构示意图。 具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而 不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
图 1所示为本发明实施例一提供的通信设备用散热拒的结构示意图。 如 图 1所示， 通信设备用散热拒 100包括拒体 101和至少一个蒸发器 102。
其中， 拒体 101 包括多个壁板， 其中的多个壁板中的的至少一个壁板为 冷凝板 103 , 冷凝板 103上设置有冷凝管路 104, 蒸发器 102位于拒体 101中 远离地面的一端，蒸发器 102内部具有相变媒介，蒸发器 102与冷凝管路 104 相连接以形成相变媒介运动的循环回路， 相变媒介在蒸发器 102端通过相变 的方式吸收热能， 并在冷凝管路 104中通过相变的方式释放所吸收的热能。
可选地， 还可以在该通信设备用散热拒 100中设置风机 (图中未示出）， 风机可以加快蒸发器 102内的相变媒介与热量的交换。 由于该通信设备用散 热拒 100是密封的， 即使其内部还存在有风机， 也会由于拒体的隔音作用使 得噪音较小。
本实施例中的蒸发器 102与冷凝管路 104之间的连接方式如图 1所示， 相变媒介的出口和入口可以均位于蒸发器 102中的同一侧， 这样会使得蒸发 器 102与冷凝管路 104之间的连接管路的耗材较少， 降低生产成本。
制作冷凝板 103的材料可以是铝合金、 不锈钢和塑料中的任意一种。 冷 凝板 103的冷凝管路 104可以以焊接的方式形成于冷凝板 103上， 优选地， 冷凝管路 104通过吹胀技术形成于冷凝板 103中。 这样， 冷凝管路 104与冷 凝板 103成为一体， 也就是说相变媒介在冷凝管 104中的运动即是在冷凝板 103 中运动， 能够与外界做最大限度地接触， 而不需要再经过其它设备或管 路才能将热量传递到外界， 增强了散热能力。 可选地， 蒸发器 102可以采用 平行流换热器。
上述通信设备用散热拒 100的具体工作原理是， 蒸发器 102中的相变媒 介吸收了足够的、 由通信设备产生的热量之后， 发生物理相变， 例如从液相 变化到气相， 由于自身的物理作用或者作用到该相变媒介的外部作用力， 使 得发生了相变的相变媒介运动到冷凝板 103中的冷凝管路 104中。 由于冷凝 板 103是作为拒体 101的一部分， 与外界直接接触， 所以相变媒介可以在通 过冷凝板 103时与外界做热量交换 , 即进行散热。 当相变媒介散发出的热量 到一定程度时， 相变媒介会重新回到常温下的状态， 例如从气相回到液相， 并通过相变媒介自身的物理作用和 /或作用到相变媒介的外部作用力， 利用冷 凝管路 104和蒸发器 102之间的循环回路重新回到蒸发器 102中。如此循环， 以达到为该通信设备用散热拒 100散热的目的。
可选地， 相变媒介是氨、 水、 丙酮和氢氟烃制冷剂中的任意一种， 其中， 氢氟烃制冷剂具体可为 R134制冷剂。 这样， 相变媒介在室温状态下是液体， 而吸收一定的热量之后就会变成气体， 由于气体本身的扩散性， 其将会进入 到冷凝管路 104中， 通过与外界的热交换， 就可以将热量散发掉， 相变媒介 重新回到液体的状态， 并返回至蒸发器 102。 当相变媒介在运动时， 整个循 环管路内部就都具有相变媒介，对于蒸发器 102来说，相变媒介从蒸发器 102 流出的口设定为出口， 流入的口设定为入口。 可通过位于该通信设备用散热拒 100中的辅助装置 （图中未示出） ， 所 路中流动。辅助装置例如是毛细管结构或者动力驱动装置，均靠近蒸发器 102, 例如位于蒸发器 102的正下方。 例如， 当采用能够提供毛细力的毛细管结构 且循环回路内具有一定的负压时， 常温下为液体、 吸收热量后为气体的相变 媒介， 能够自行在毛细管结构中运动， 这样该蒸发器 102就不需要采用任何 会产生噪音的辅助装置了， 大大降低了噪声扰民的可能性。 采用动力驱动装 置时， 例如泵， 可以加快液相的相变媒介的流动以增强该相变媒介的吸热和 散热效果。 动力驱动装置的噪声一般较风机来说要小的多， 因此， 与传统技 术相比较， 能够在一定程度上降低噪声。
根据上述实施例， 通过将蒸发器 102安装在拒体 101的上端部分， 即远 离地面的一端， 由于热量都是向上运动的， 因此， 对于该通信设备用散热拒 100来说， 热量主要是集中在拒体 101的上部， 因此将蒸发器 102安装在拒 体 101 的上端部分能够最大限度的吸收热量， 而且， 由于通信设备通常较沉 重且具有精细的电路结构， 一般不能在其上再任意增加任何装置以将其挂置 在拒体侧壁上， 否则会影响其通信效果甚至破坏其性能， 因此通常都是将通 信设备放置于拒体 101的底部。本发明实施例中将蒸发器 102设置在拒体 101 的上端部分， 能够避免占用通信设备的地方， 从而减小整个通信设备用散热 拒的尺寸。 将蒸发器 102设置在拒体 101的上端部分有很多种方式， 例如在 蒸发器 102直接焊接在拒体 101上， 或者在蒸发器 102上焊接挂钩并在拒体 101 的顶面内部的相应位置设置连接挂钩的地方， 从而将蒸发器 102悬挂于 拒体 101远离地面的一端。
另外， 还可以根据实际设置蒸发器 102与冷凝板 103之间的距离， 当两 者之间的距离较小时，蒸发器 102与冷凝管路 104之间的管路相应地就较短， 可以以最快的速度将相变媒介送入冷凝管路 104中进行散热， 不仅降低了成 本， 而且增强了散热能力， 避免相变媒介在未到达冷凝管路 104时又将部分 热量重新散发在拒体 101 中。 使用本发明实施例的通信设备用散热拒 100, 能够减小甚至避免噪音的产生， 散热能力与传统技术相比提供 50%以上。 如 果将该通信设备用散热拒 100设计成封闭式， 还能够避免积尘的风险。
本实施例二对实施例一的通信设备用散热拒做进一步地改进。 本实施例 二中， 在蒸发器 102中设置槽道结构， 如图 2A、 2B和 2C所示， 分别为具有 槽道结构的蒸发器 102的各种截面示意图。 槽道结构能够扩大蒸发器 102的 吸热面积， 这样也就进一步地增强了该通信设备用散热拒 100的散热能力。
本实施例三对实施例一和实施例二的通信设备用散热拒 100做进一步地 改进。 如图 3所示， 本实施例三中， 在冷凝板 103朝向外界环境的一侧具有 至少一个翅片 202, 该翅片 202增强冷凝板 103的散热能力， 使得该通信设 备用散热拒 100的散热能力进一步增强。
本实施例四对上述实施例的通信设备用散热拒进行改进。 图 4中示出了 根据本实施例四的通信设备用散热拒 400的结构示意图。 该通信设备用散热 拒 400的相变媒介的出口与入口位于蒸发器 102相对的两侧， 出口位于蒸发 器 102靠近冷凝板 101的一侧，入口位于蒸发器 102远离冷凝板 101的一侧， 其它结构均与实施例一中的结构一致， 在此不再进行赞述。
这样， 相变媒介从出口出来进入到冷凝管路 104进行散热， 再从冷凝管 路 104中流出沿着冷凝管路 104与蒸发器 102之间的连接管路返回到蒸发器 102 中。 由于这段连接管路较长， 因此相变媒介在这段连接管路中存在的时 间就较长， 可以在一定程度上吸收热量， 并携带这部分热量回到蒸发器 102 中。 这样， 也就是变相地扩大了相变媒介的吸热面积， 增强了该通信设备用 散热拒 400的吸热效果， 相应地， 也就增强了该通信设备用散热拒 400的散 热效果。
在实际应用中， 可以根据需要或者根据通信设备在该通信设备用散热拒 400中的摆放位置， 来设计蒸发器 102和冷凝管路 104之间的连接管路的形 状， 在尽量不影响到通信设备的情况下， 尽可能地靠近通信设备， 以使相变 媒介的吸热效果更好， 以进一步地更好地散热。
根据本实施例四的通信设备用散热拒 400,通过将相变媒介在蒸发器 102 上的出口和入口分别设置在蒸发器 102的相对两侧， 并尽量延长蒸发器 102 和冷凝管路 104之间连接管路的长度， 以变相地扩大该蒸发器 102的吸热面 积， 进一步地， 增强该通信设备用散热拒 400的散热效果。
本发明实施例提供的通信设备用散热拒可以用于各种通信设备， 例如交 换机、 电源和防雷盒等等， 可以根据这些通信设备来设计通信设备用散热拒 的实际尺寸。
在上述实施例中， 对各个实施例的描述都各有侧重， 某个实施例中没有 详述的部分， 可以参见其他实施例的相关描述。
