本发明实施例提供了一种散热装置， 其可用于对通信设备进行散热， 尤其 适用于车载通信设备， 具体请见图 1。
由图 1 所示可知， 本实施例提供的散热装置包括机壳 101 和散热鳍片组 亂
在该机壳 101下部设置有容置空间，在该容置空间内部可放置通信设备的 发热热源， 在机壳 101上部设置的散热鳍片组 102可与发热热源热连接， 进而 吸^发热热源的热量， 从而对发热热源进行散热。
为加强散热的效果， 本实施例中，在散热鳍片组 102的任意一端设置有凹 窝部 103 , 并在凹窝部 103内设置有用于产生散射冷风的离心式风扇， 该离心 式风扇的具体结构为现有技术， 在此不再贅述。
具体的， 位于凹窝部内的离心式风扇产生的散射冷风流向散热鳍片组 102 的进风端，并沿该散热鳍片组 102的排列方向对该散热鳍片组 102吸收的热量 进行散热。
即位于所述凹窝部 103内的离心式风扇在散热过程中会发出散射冷风，该 散热冷风沿散热鳍片组 102中散热鳍片之间的缝隙吹入散热鳍片组，该散热鳍 片组 102 中散热鳍片之间的缝隙靠近所述离心式风扇的一端即为散热鳍片组 102 的进风端。 该离心式风扇吹出的散射冷风经由该进风端吹入散热鳍片组 亂
吹入该散热鳍片组 102 的散射冷风即可对各个散热鳍片所吸收的热量进 本实施例中， 因在凹窝部 103内部设置离心式风扇，使得离心式风扇的散 射冷风直接流向散热鳍片组 102, 提升了散热的效率， 而且将离心式风扇放置 在散热鳍片组的一端，从而有利于该离心式风扇吹出的散射冷风沿所述散热鳍 片组 102的一端吹向另一端。
图 1所示实施例对本发明实施例所提供的散热装置进行说明，为进一步提 升散热效果， 以下结合图 2所示的实施例对该散热装置的结构进行详细说明： 由图 2可知，位于机壳 201上部的散热鳍片组 202包括平行鳍片组和*** 鳍片组；
其中，位于区域 203所示的区域内部的散热鳍片组为平行鳍片组，位于区 域 204所示的区域内部的散热鳍片组为***鳍片组。
进一步的， 平行鳍片组包括多个平行鳍片 205 , 且该平行鳍片 205彼此之 间相互平行；
***鳍片组包括多个***鳍片 206。
更进一步的， 该***鳍片 206由平行鳍片 205第一端延伸形成， 即***鳍 片 206与平行鳍片 205呈一体设置。
为使得离心式风扇 207的散射冷风能够顺利的流向散热鳍片组 202的进风 端， 则使得***鳍片组围绕该凹窝部 208并形成涡轮状， 进而使得位于凹窝部 208内的离心式风扇 207能够将散射冷风吹入散热鳍片组 202的进风端。
需明确的是， ***鳍片组围绕该凹窝部 208 形成涡轮状为一种较佳的示 例， 即***鳍片组围绕该凹窝部 208形成的具体形状在本实施例中不作限定， 例如还可形成圓形， 椭圓形或不规则形状等。
本实施例中， 散热装置的散热鳍片具体包括有平行鳍片组和***鳍片组， 且***鳍片组围绕该凹窝部 208并形成涡轮状。在本实施例中， 利用离心式风 扇 207产生的横向散射冷风即可达到涡轮风扇的效果。
图 1和图 2所示实施例对散热装置的结构进行了详细说明， 以下结合图 3 所示的实施例说明该散热装置具体是如何进行散热的：
本实施例中的凹窝部 301 呈蛋形， 由图 3所示可知， 该呈蛋形的凹窝部 301具有顶端和底端， 且顶端的面积小于底端的面积， 且该离心式风扇 302设 置在该凹窝部 301的底端。
具体的，该凹窝部 301顶端对应的***鳍片与该离心式风扇 302之间的第 一区域大于该凹窝部 301底端对应的***鳍片与该离心式风扇 302之间的第二 区域；
更具体的，该 窝部 301侧壁对应的***鳍片与该离心式风扇的距离沿该 凹窝部 301顶端至底端的方向依次递减。
通过本实施例的设置方式使得在具体的散热过程中 ,该散热装置形成加压 区域 303、 译放区域 304以及过渡区域 305。
本实施例以该离心式风扇 302为逆时针旋转为例；
该加压区域 303是该离心式风扇 302与凹窝部 301的底端最接近的区域， 因***鳍片组围绕该凹窝部 301形成涡轮状，所以该加压区域 303也是该离心 式风扇 302与***鳍片组最接近的区域。
该离心式风扇 302形成的散射冷风在狭小的加压区域 303内被压缩，从而 使得沿逆时针方向流出加压区域 303的散射冷风的风压加大。
沿逆时针方向流出加压区域 303的散射冷风流入译放区域 304。
其中，位于该译放区域 304内的***鳍片的进风端与该凹窝部 301的侧壁 对应，并且顺着该离心式风扇 302风扇旋转的方向逐渐远离该离心式风扇 302。
由图 3所示可知， 位于译放区域 304内的***鳍片的进风端是最密集的， 只有经过加压区域 303 加压后的散射冷风才能流入， 而且经过加压区域 303 加压后的散射冷风大部分在译放区域 304译放。
过渡区域 305位于蛋形凹窝部 301的前端， 并起到调节作用， 因位于该过 渡区域 305内的***鳍片的进风端与离心式风扇 302的距离大于位于译放区域 304内的***鳍片的进风端与离心式风扇 302的距离， 又因大量的散射冷风在 译放区域 304被译放掉，进而使得流经过渡区域 305的风量小于流经过渡区域
304被译放的散射冷风的风压。
在进风端位于译放区域 304 内的散热鳍片组下方可设置功耗大的发热热 源 , 较佳的 , 进风端位于译放区域 304内的散热鳍片长且多。
在进风端位于过渡区域 305 内的散热鳍片组下方可设置功耗小的发热热 源， 较佳的， 进风端位于过渡区域 305内的散热鳍片短且少。
继续参见图 3 , 平行鳍片组的第一端延伸设置***鳍片， 而平行鳍片组的 第二端设置为钉状鳍片组， 该钉状鳍片组位于区域 306内。
该钉状鳍片组包括多个钉状鳍片分组，且该钉状鳍片分组沿该平行鳍片延 伸方向排列， 即使得钉状鳍片分组之间相互平行。
该钉状鳍片分组包括多个钉状鳍片，通过该钉状鳍片进行散热，从而使得 散射冷风的流向被打乱。
在具体设置过程中， 可将平行鳍片的末端以一定的间距进行打断，从而形 成钉状鳍片，钉状鳍片之间的距离可以相等也可以不相等，在本实施例中不作 限定。
该钉状鳍片能够增加散热面积，而且能够扰乱散热鳍片的末端的散射冷风 的流向。
更佳的是， 该钉状鳍片具体设置位置也可随机进行排布， 随机排布的钉状 鳍片能够更好的扰乱散热鳍片的末端散射冷风的流向。
本实施例中， 散热装置在散热过程中形成加压区域 303、 译放区域 304以 及过渡区域 305 , 且流经不同区域的风量大小不同， 而且本实施例中散热鳍片 组的形状， 方向以及分布可根据发热热源位置以及大小的不同进行设置，且散 热鳍片组呈流线型设置，散热鳍片组的进风端与离心式风扇呈一定的角度， 进 风端都沿散射冷风的方向进行设置，且在平行散热鳍片的第二端设置有钉状鳍 片从而能够使得散热风能够在末端沿着不同的风向进行散热。
以上实施例对本发明实施例所提供的散热装置的具体结构进行详细说明， 以下以具体应用场景对本发明实施例所提供的散热装置的具体结构进一步详 细说明：
在散热装置的机壳上部设置散热鳍片组；
该散热鳍片组中包括多个散热鳍片， 该散热鳍片可为铝合金， 黄铜或青铜 制成；
在本应用场景中， 该散热鳍片可为铝合金制成；
在散热装置的机壳内部用于放置发热热源 ,该散热鳍片组为该发热热源进 行散热， 即该散热鳍片组为该散热装置的主要散热结构；
在本应用场景中，放置在机壳内部的发热热源可以是车载通信设备的 PCB 板；
本应用场景中， 可在散热鳍片底端与 PCB板接触面涂上一层导热硅脂， 使 PCB板上的元器件发出的热量更有效的传导到散热鳍片上；
散热鳍片组包括平行鳍片组和***鳍片组；
该平行鳍片组中的平行鳍片彼此之间相互平行， 且延伸形成***鳍片； 即平行鳍片与***鳍片呈一体化设置， 并呈流线型；
在***鳍片组的一端形成凹窝部， 且围绕该凹窝部形成涡轮状； 该凹窝部呈蛋形；
凹窝部的顶端的面积小于凹窝部底端的面积；
在凹窝部的底端设置该离心式风扇；
***鳍片的进风端与凹窝部的***对应，且进风端与离心式风扇呈一定的 角度；
与凹窝部顶端对应的***鳍片与该离心式风扇之间的第一区域大于该凹 窝部底端对应的***鳍片与该离心式风扇之间的第二区域；
使得离心式风扇距离凹窝部底端的距离小于该离心式风扇距离凹窝部顶 端的 巨离；
该凹窝部侧壁对应的***鳍片与该离心式风扇的距离沿该凹窝部顶端至 底端的方向依次递减；
在散热装置具体散热过程中，散热装置形成的散热区域分为加压区域、释 放区 i或以及过渡区 i或；
本应用场景中， 以离心式风扇为逆时针旋转为例；
在具体散热过程中， 该加压区域与凹窝部底端最接近， 离心式风扇发出的 散射冷风流经加压区域后被加压；
加压后的散射冷风沿逆时针方向流出该加压区域， 并进入释放区域； 位于译放区域内的***鳍片的进风端沿逆时针方向逐渐的远离离心式风 扇；
且进风端位于译放区域内的散热鳍片的数量较多， 而且比较长， 与该处的 散热鳍片对应的下方可设置功耗大的发热热源；
因位于译放区域内的散热鳍片的进风端比较密集，所以加压后的散射冷风 大部分在此处译放；
在凹窝部的前端设置有过渡区域，位于该过渡区域内的***鳍片的进风端 与离心式风扇的距离大于位于译放区域内的***鳍片的进风端与离心式风扇 的 巨离；
因大部分散射冷风在译放区域被释放，所以在过渡区域译放的散射冷风的 风量小于在译放区域内被译放的散射冷风；
相对于进风端位于译放区域内的散热鳍片，进风端位于过渡区域内的散热 鳍片的数量较少，且长度较短， 与该处的散热鳍片对应的下方可设置功耗较小 的发热热源；
将平行鳍片的尾端以一定的间距进行打断， 以形成钉状的散热鳍片，从而 使得散射冷风的流向被打乱， 有益于散射冷风从多方向进行散热。
本发明实施例提供一种通信设备，较佳的，该通信设备可应用在车载领域， 具体请参见图 4;
该通信设备具体可包括散热装置 401、控制面板 402、顶盖 403、隔板 404、 PCB板 405和底盖 406。
其中 , 该散热装置 401分别与隔板 404、控制面板 402、 和底盖 406连接。 散热装置 401的具体结构请参见图 1至图 3所示实施例， 在此不再贅述。 由图 4可知 , 该隔板 404设置在该散热装置 401上部 ,且该隔板 404与该 散热装置 401形成不封闭的腔体。
该顶盖 403设置在该隔板 404上部，且顶盖 403与隔板 404连接， 并形成 一定的空间。
该控制面板 401设置在该机壳 407前部。
该 PCB板 405设置在该机壳 407内部。
该底盖 406设置在该 PCB板 405下部。
且该底盖 406与该机壳 407形成封闭腔体，其该封闭腔体内容置有该 PCB 板 405。
本实施例中的通信设备通过其散热装置进行散热 ,散热装置设置在通信设 备的内部， 进而散热装置的离心式风扇不外露， 从而具有很好的防尘效果， 可 靠性高。
图 4所示的实施例对通信设备的结构进行了详细说明，以下结合图 5所示 的实施例详细说明该散热装置具体是如何实现散热的；
为实现通信设备的正常工作，则位于散热装置内部的离心式风扇需要发出 散射冷风， 则需要该通信设备具有进风口。
在本实施例中， 将进风口 501设置在控制面板 502的上侧， 其中， 进风口 501具体的设置位置也可见图 6所示。
由图 6可知， 因将进风口 501设置在控制面板 502的上侧，通过该位于控 制面板 502外部上侧的进风口 501能够将外界的冷风吸入该散热装置。
其具体的设置方式为，在隔板 503与该顶盖 507之间设置有进风通道 504; 因离心式风扇 505的工作，使得在散热装置内部形成负压， 进而使得外界 的冷风能够从进风口 501吸入进风通道 504内。
为使得吸入进风通道 504内的冷风能够流向该离心式风扇 505 , 则在该隔 板 503上设置有通孔 506。
即散热装置外界的冷风由该进风口 501流入进风通道 504内，并经由通孔 506流向离心式风扇 505。
本实施例较佳的可实现嵌入式安装， 即只将控制面板 502露出， 则为保障 该通信设备的散热效果，需要该通信设备具有多方位出风，具体的实现方式为； 在隔板 503与顶盖 507之间设置有出风通道 508。
为使得通信设备的出风与进风能够互不干扰，提升散热效果和效率， 则使 得该出风通道 508与该进风通道 504通过该隔板 503能够彼此隔离。
在机壳的侧面， 且与该出风通道 508对应位置设置有第一出风口 509。 具体的， 离心式风扇 505发出的散射冷风流向散热鳍片组，且该第一出风 口 509设置在散热鳍片组的尾端，从而使得流经散热鳍片组的散射冷风能够从 第一出风口 509流出通信设备。
为提升散热效果，散热鳍片组还可在平行鳍片的末端设置钉状鳍片，钉状 鳍片使得散射冷风能够通过不同的风向进行散热，为使得流经钉状鳍片的散射 冷风能够顺利的流出该通信设备， 则在该通信设备的顶盖 507上，且与该出风 通道对应位置设置有第二出风口 510。
该第二出风口 510可设置为多个。
散热装置的钉状鳍片可对散射冷风的流向进行扰乱，从而使得被扰乱的散 射冷风能够从多个该第二出风口 510流出通信设备，避免出风口被遮挡而影响 散热效果。
在该机壳后部设置有用于连接电源和数据信号源的外接端口。
本实施例中， 通信设备内置有散热装置， 以使得散热装置的离心式风扇 505位于通信设备的内部， 从而具有很好的防尘效果； 而且该散射设备使得外 界的冷风由该进风口 501吸入进风通道 504内，并经由通孔 506流向离心式风 扇 505 , 从而使得离心式风扇能发出均匀的散射冷风， 且该通信设备具有多个 出风口， 而且出风口与进风口彼此隔离， 从而不会互相干扰， 提升散热效果。
图 4至图 6所示的实施例对通信设备的具体结构进行详细说明，以下举具 体应用场景对该通信设备进行进一步的详细说明：
在本应用场景中， 该通信设备为车载通信设备， 应用在车载领域； 该通信设备的顶盖与隔板形成不封闭的腔体；
隔板下方设置有散热装置；
散热装置的机壳前部设置有控制面板；
散热装置的机壳下部与底盖形成封闭的腔体；
在该封闭的腔体内部设置有 PCB板；
该车载通信设备嵌入式安装于汽车的中控台，且该控制面板外露于汽车的 中控台， 使得用户能够通过外露的控制面板输入控制指令；
在控制面板的上侧排列设置有进风口；
因汽车内部的温度低于嵌入式安装于该中控台内的温度；
且因位于车载通信设备内部的离心式风扇的运转，会在该设备内部形成负 压，进而使得将外界的冷风通过位于控制面板外侧的进风口吸入车载通信设备 内部；
隔板与顶盖设置有进风通道和出风通道， 且进风通道与出风通道彼此隔 离；
在隔板上， 与散热装置内的离心式风扇对应位置设置有通孔；
车载通信设备外界的冷风通过控制面板上的进风口被吸入进风通道，并经 由通孔流向离心式风扇；
离心式风扇根据冷风生成均匀的散射冷风；
该散射冷风流向散热装置的散热鳍片组；
该散热鳍片组的尾端为钉状鳍片， 其使得散热风的流向被打乱； 一部分散射冷风通过第一出风口流出车载通信设备，一部分散射冷风通过 第二出风口流出车载通信设备；
该第一出风口设置在机壳侧面， 且与该出风通道对应；
第二出风口设置在顶盖上，且与该出风通道对应， 该第二出风口可设置成 多个。
以上所述， 以上实施例仅用以说明本发明的技术方案， 而非对其限制； 尽 管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理 解： 其依然可以对前述各实施例所记载的技术方案进行修改， 或者对其中部分 技术特征进行等同替换； 而这些修改或者替换， 并不使相应技术方案的本质脱 离本发明各实施例技术方案的精神和范围。
