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作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。
请参阅图1及图2，本发明的第一实施例提供一种用于基站模块的散热装置10。所述散热装置10装设于基站模块，从而对所述通信基站的基站模块进行散热，保证所述基站模块在工作状态下保持在合适的温度条件下。所述通信基站模块可包括但不限于射频拉远模块(Radio Remote Unit，RRU)、基带控制模块(Base Band Unit，BBU)、电源模块等。
所述散热装置10包括壳体12、第一散热模组15、第二散热模组17。所述第一散热模组15设置于所述壳体12的外部并连接于所述壳体12。可以理解的是，本实施例中，所述散热装置10的壳体12可即为所述基站模块的壳体12，可用于收容所述基站模块的各类电气元件并将热量传递至第一散热模组15、第二散热模组17以使基站模块散热降温。所述基站模块也可另行设置模块外壳，而所述散热装置10的壳体12采用任意使用方式连接于模块外壳之上。可以理解的是，所述壳体12的外形及内部结构可按需自行设置。
所述的基站模块还设有连接于所述壳体12的面板19及设置于壳体12内部的电气元件(图未示)，如各类接口元件、收发元件、光学分波合波元件等，其结构、用途在此不再赘述。
所述第一散热模组15包括至少两个间隔设置的第一散热齿152，第一散热齿152设置于壳体12外部。所述第一散热齿152设有第一齿根1522及第一 齿顶1523，所述第一散热齿152的第一齿根1522连接于所述壳体12。所述第一散热齿152用于吸收来自壳体12的热量并向外部环境散发。
在本实施例中，所述第一散热齿152呈条形片状。所述第一散热齿152与所述挡板连接的边为长边，与所述长边相邻的边为短边。所述第二延伸方向Y为远离所述壳体12的方向，所述第一延伸方向X垂直于所述第一延伸方向X。
在本实施例中，壳体为立方体，所述第一散热齿152的长边沿平行于所述壳体12的第一延伸方向X延伸。所述第一散热齿152的短边垂直于所述第一延伸方向且沿远离所述壳体12的第二延伸方向Y延伸。
第一散热齿152可设置于所述壳体12的各个需要加强散热的面。相邻的两个第一散热齿152之间的间隙可供空气流动，从而形成供气流流动的流道100。所述散热装置10外部的流动空气于所述流道100内流动，以便降低散热装置10的热量。
所述第二散热模组17包括挡板172。所述挡板172连接于所述第一散热齿152的第一齿顶1523并接收来自所述第一散热齿152的热量。在本实施中，所述挡板172设有第一表面(图未示)及设置于所述第一表面背面的第二表面1721。第一散热齿152连接于所述挡板172的第一表面。
在本实施例中，所述挡板172呈条形板状，所述挡板172横跨至少一个流道100。进一步的，所述挡板172可大致垂直于所述第一散热齿152。可以理解的是，所述挡板172可采用焊接、一体成型或其他任意适用方式连接于所述第一散热齿152的第一齿顶1523。可以理解的是，所述挡板172的尺寸可根据需要自行设置。
本发明的散热装置10可设置于通信基站的基站模块外部，通过第一散热齿152吸收散发壳体12的热量，并进一步通过设置挡板172实现二次散热，强化散热装置10与外部冷空气的热交换效果。且在气流流经散热装置10的过程中，通过设置挡板172覆盖第一散热齿152形成的流道100，从而阻碍气流自流道100中流出，保证气流可于流道100中深入第一散热齿152的第一齿根1522，从而保证温度较高的第一齿根1522处的散热效果。
如图3及图4所示，本发明的第二实施例提供一种散热装置20，本实施 例中的散热装置20与第一实施例大致相同，包括壳体22、第一散热模组25及第二散热模组27。所述第一散热模组25包括至少两个相互之间间隔设置的第一散热齿252设置于壳体22外部，所述第一散热齿252设有第一齿根2522及第一齿顶2523，所述第一散热齿252的第一齿根2522连接于所述壳体22。第二散热模组27包括挡板272，所述挡板272连接于所述第一散热齿252的第一齿顶2523。

在本实施例中，所述散热装置20设有至少两片间隔设置的第二散热齿273。可以理解的是，所述第二散热齿273的设置数量及间隔距离可按需自行设置。
通过设置第二散热齿273的齿间距及齿厚，可提升第二散热齿273与外部冷空气的换热效率，提升散热装置20的整体散热效果。较优的，所述第二散热齿273的齿厚小于所述第一散热齿252的齿厚。相邻的两个所述第二散热齿273之间的齿间距小于相邻的两个所述第一散热齿252之间的齿间距。
本实施例中的散热装置20通过在挡板272上设置第二散热齿273，从而增强第二散热模组27的散热能力，从而可提升散热装置20的整体散热效果。
进一步的，在使用时，空气流动上升的过程中，第二散热齿273可对流动的空气起到扰流效果，促进空气在两个相邻第一散热齿252之间的流道200内部流动，并较为接近所述第一散热齿252的第一齿根2522，从而提升散热装置20的散热效果。

不同之处在于，在本实施例中，所述第一散热模组35的每一第一散热齿352的第一齿顶3523设有一凸部3525，所述凸部3525位于所述第一散热齿352所在平面内，并朝向远离所述第一齿根3522的方向凸起。所述挡板372的第一表面连接并覆盖于所述第一齿顶3523的凸部3525。
可以理解的是，所述每个第一散热齿352的第一齿顶3523均可设置一个第一凸部3525，且各个第一凸部3525的形状及凸起尺寸可相同，从而便于所述挡板372平整连接于所述第一散热模组35。
本实施例中的散热装置30通过设置第一凸部3525，从而加强所述挡板372与壳体32之间的空间的散热效果，提升第一散热模组35的散热效果，进而提升散热装置30的整体散热效果。
