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。
参阅附图1-附图9，一种计算机网络设备用的散热装置，与交换机1均安装在主框架2上，并用于驱散交换机1产生的热量，该计算机网络设备用的散热装置包括导热机构3和驱热机构4；导热机构3包括导热块31和固定板32，固定板32安装在导热块31上，导热块31内部镂空，且朝两侧开口设置，导热块31与固定板32固定连接，导热块31通过固定板32安装在主框架2上，并与交换机1贴合，用于引导交换机1产生的热量至固定板32上；驱热机构4安装在导热块31一侧的开口处，并用于将引导到固定板32上的热量从导热块31的另一侧开口驱散出去。
具体的，主框架2具体为放置交换机1的机柜内部的框架，在主框架2上，多个交换机1和多个该散热装置按照堆叠的方式，依次固定到主框架2上。如附图1所示，使得每个交换机1上表面和下表面都与该散热装置的导热块31贴合连接，其中导热块31的材料可选用铜、铝或者铜铝搭配材料，由于企业级的交换机1的体积较大，导热块31需要与交换机1的上表面和下表面最大化的接触才能有着更佳的导热效果，因此导热块31的所对应的体积也需要与交换机1相近，再加上该散热装置需要运维人员的组装到机柜上，因此重量不能太大，所以从材料的成本以及密度质量上，选择铝材料要比铜材料要经济实用，而采用铜铝搭配的导热块31虽然能够将两种材料的优势相互利用到，但是其在加工工艺的制造难度及设计上需要花费时间成本，因此在本实施例中的导热块31采用的是纯铝材料。交换机1在运作过程中产生的热量大多都会被接触到交换机1上下表面的两个导热块31所引导而出，而导热块31的形状类似于中空的方形柱，使其与空气的接触表面积增大，提高了散热效率，同时驱热机构4安装在导热块31一侧的开口处，驱热机构4能够将导热块31所引流的热量不断从导 热块31的另一侧开口处排出，这里需要将交换机1设有网口的一侧与安装有驱热机构4的导热块31开口处同一侧，由于交换机1设有网口的一侧需要安插多根网线，若是网线都集中在热量排出的位置上的话，网线容易出现受损和积灰的情况，进而导致无法使用，影响到网络的正常运作，而且还增大了运维成本，这种交换机1与散热装置的堆叠方式增大了机柜对交换机1的容纳量，其中交换机1是被两个散热装置夹在中间，这也使得灰尘不易落到交换机1上，避免了积灰的情况。
基于上述方案，具体的实施步骤如下：
将交换机1通过直角连接件和螺丝固定在主框架2上，再将导热块31通过固定板32和螺丝固定在主框架2上，在固定的同时，保证导热块31与交换机1相互贴合，在上述安装的基础上，其余多个交换机1与多个导热块31的安装同理，其中需要注意的是，每台交换机1都需要有两个导热块31贴合于上下两个表面上，交换机1于导热块31安装完成后，再将多个驱热机构4分别安装到对应的导热块31的开口处，交换机1运作时所生产的热量会被上下两个导热块31所引流吸收，并在驱热机构4的驱散下，将滞留在导热块31内的热量从导热块31的开口处排出。
进一步的，导热块31包括上导热板311和下导热板312，上导热板311与下导热板312相互可拆卸连接，上导热板311与下导热板312相向的一侧均设有多个散热片313，固定板32设有两个，并分别固定在上导热板311与下导热板312的两侧上，上导热板311和下导热板312上均设有散热孔314。
参阅附图4和附图5，上导热板311和下导热板312的两侧均设有可相互嵌套连接的扣件，且均采用钣金工艺折弯形成的，上导热板311与下导热板312上的散热片313为了增大与空气接触的表面积，其中上导热板311上的散热片 与下导热板312上的散热片313在上导热板311与下导热板312嵌套连接的时候会相互错开，以保证散热片313之间所引流的热量不会相互干扰而影响散热效率，且散热片313的错开也方便了与空气接触时的热量置换。
进一步的，驱热机构4包括主壳体41、固定组件42和多个驱热风扇43，主壳体41内部设有一侧开口的空腔，固定组件42安装在主壳体41上，并用于将主壳体41开口的一侧固定在导热块31的开口处，多个驱热风扇43分别安装在主壳体41内，且驱热风扇43的吹风向朝向主壳体41的开口处，主壳体41对应多个驱热风扇43的位置设有多个引风孔411。
参阅附图8，主壳体41内设有多个用于安装驱热风扇43的安装卡槽，其结构与市面上服务器安装散热风扇的结构类似，这处不再加以赘述，主壳体41通过固定组件42固定在导热块31的开口处，其中主壳体41在固定时需要保证主壳体41的开口一侧需要与导热块31的开口处相贴合固定，这样才能保证驱热风扇43有效地将风引流到导热块31内，将引导到散热片313上的热量置换到空气中，并从导热块31的另一侧开口处排出，其中在交换机1与导热块31贴合安装时，两者是很难达到完全贴合的状态，都会出现凹凸不起的缝隙，影响交换机1热量的传导，除非采用CPU利用硅脂与散热器紧密贴合的方式，但是这样需要用到大量类似硅脂一般的材料，其成本较高，且后续在对该散热装置进行拆卸清灰时，还需要将硅脂清理掉，在安装回去时也需要重新补充硅脂，耗时耗力而且还耗资金，因此在该散热装置上的上导热板311和下导热板312均设有多个散热孔314，驱热风扇43所驱使的驱热风会进入导热块31内，驱热风除了在经过导热块31与其和散热片313进行热量置换同时，也从散热孔314出去与交换机1的上下表面接触，并进行热量置换，以提升了该计算机网络设备用的散热装置的散热效果。
进一步的，固定组件42包括内部空腔设置的副壳体421以及均安装在副壳体421内的固定杆422和弹性件423，固定板32上设有固定孔321，副壳体421一侧设有与内部接通的通孔421a，固定杆422可滑动地安装在副壳体421内，固定杆422的第一端伸出通孔421a并与固定孔321卡接，弹性件423一端与副壳体421内壁连接，另一端与固定杆422连接。
副壳体421上还设有导向孔421b，固定杆422的第二端设有推拉件422a，推拉件422a从导向孔421b处伸出。
具体的，固定组件42设有两组，且分别对称安装在主壳体41的两侧上，在将驱热机构4安装到导热机构3上时，固定杆422的第一端在弹性件423的作用力下，是处于伸出通孔421a并置于外界，使用者在将驱热机构4固定到导热机构3上时，需要通过外力驱使推拉件422a沿导向孔421b的长度方向上移动，使得固定杆422的第一端从通孔421a缩回到副壳体421内，在将主壳体41的开口处与导热块31的开口处贴合时，通孔421a的位置与固定孔321的位置想齐平，此时，即可松开推拉件422a，固定杆422的第一端便会在弹性件423的作用力下重新伸出通孔422a，并与固定板32上的固定孔321卡接，以完成驱热机构4与导热机构3的固定连接，使用者需要将驱热机构4和导热机构3进行拆卸时，同样采用上述的操作流程即可。
进一步的，驱热机构4还包括缓震件44，缓震件44设置在主壳体41开口处的边缘上，且不封闭主壳体41的开口。
具体的，由于驱热风扇43在运作时，会发生一定频率的震动，而数量多的驱热风扇43同时运作，便会带来较大的噪音，而这中震动甚至可能给交换机1带来硬件上的损坏，因此在主壳体41的开口处手缓震件44，具体为EVA材料，其具有防静电、吸音和缓震效果，能够有效的减缓驱热风扇43所带来的震动以 及噪音。
