发热组件200，发热组件200的一端设置有光连接器210，另一端设置有电连接器220；
液冷壳体100，包括容置部、冷却液输入口110和冷却液输出口120，容置部包裹发热组件200并设有分别对应光连接器210和电连接器220的开口，冷却液输入口110和冷却液输出口120连通到液冷壳体100的内腔以形成冷却液流路。
发热组件200指在工作过程中光模块发热的部分，包括但不限于电源模块、激光器和管控单元等，由于大容量光模块中这些模块的发热量很高，传统风冷散热已经无法满足需要，因此本申请实施例利用液冷壳体100对发热组件200进行包裹，通过液冷壳体100吸收发热组件200的热量，并循环液冷壳体100内的冷却液，带走发热组件200的热量，实现液冷散热。其中液冷壳体100通过容置部包裹发热组件200，容置部与发热组件200直接接触实现热交换，也可以是发热组件200装入容置部后形成一个空腔，空腔中的空气与容置部接触实现热交换等。为了提高热传导能力，在容置部与发热组件200直接接触的情况下，可以在接触位置处设置导热材料，例如导热硅脂等，提高热传导能力。液冷壳体100还设置有冷却液输入口110和冷却液输出口120，冷却液输入口110和冷却液输出口120连接外部的冷却液循环系统，使得冷却液通过冷却液输入口110和冷却液输出口120在冷却壳体内进行循环，即在冷却液经过冷却壳体内部时吸收热量，在流出光模块之后通过冷却液循环系统释放热量，从而实现液冷散热。
其中，液冷壳体100并不是完全包裹整个发热组件200的，液冷壳体100可以分别开设有两个开口(图中未标示)分别对应发热组件200的光连接器210和电连接器220，外部接口(如光纤接头、电口连接模块等)通过对应的开口与光连接器210或电连接器220连接，因此可知，光连接器210或电连接器220可以不露出于液冷壳体100，也可以齐平液冷壳体100的开口，甚至可以突出于液冷壳体100的开口。总之，通过预留开口的方式使得光模块的前端和末端能够连接外部对应的连接器。
可以理解的是，液冷壳体100的形状可以根据实际需要设计，例如，本申请实施例的光模块兼容到常规的设备中，则将液冷壳体100设置成立体矩形并限制尺寸，从而使得光模块整体的外部尺寸兼容常规的设备。另外，液冷壳体100对发热组件200的包裹形式也可以根据实际需要设置，例如容置部为半包裹结构或者为管形包裹结构，以液冷壳体100的整体外形为立体矩形为例，在半包裹结构下，液冷壳体100可以是U形的，即从液冷壳体100的横截面看，一面开放，三面侧壁，构成U形结构，发热组件200可以从开放的一面嵌入到液冷壳体100内；在管形包裹结构下，从液冷壳体100的横截面看，四面侧壁封闭，构成管形结构，发热组件200从管口处嵌入到液冷壳体100内。液冷壳体100的容置部还可以设计成其他形状，在此不一一举例。
液冷壳体100往往是立体矩形的，因此为了方便冷却液输入口110和冷却液输出口120对接外部的冷却液循环系统，冷却液输入口110和冷却液输出口120可以设置在液冷壳体100这一立体矩形的前端面，或者冷却液输入口110和冷却液输出口120可以设置在液冷壳体100这一立体矩形的后端面。冷却液输入口110和冷却液输出口120设置在前端面的情况下，如图2所示，冷却液输入口110和冷却液输出口120朝向安装人员，光模块插入设备后，需要安装人员将冷却液输入口110和冷却液输出口120连接到冷却液循环系统。冷却液输入口110 和冷却液输出口120设置在后端面的情况下，如图1所示，设备内部可以预先设置冷却液循环系统的接头，光模块插入设备后，冷却液输入口110和冷却液输出口120自动对准预先设置的接头，从而连接到冷却液循环系统。
为了方便拔出光模块，本申请实施例的液冷壳体100的前端面设置可伸缩的拉扣部件130，在安装人员需要拔出光模块的时候，拉住前端面的拉扣部件130，将光模块拔出设备。光模块拔出之后，安装人员可以将拉扣部件130推回到光模块内部，便于光模块存储和运输。
由于本申请实施例的液冷光模块相比传统光模块多了液冷壳体100，考虑到区分度和安装方便，可以在液冷光模块的侧面设置导轨140，导轨140用于配合设备上的凹槽311进行安装，通过设计导轨140的位置和大小，也能够实现防呆安装。长条形的导轨140的设置方向可以是沿液冷光模块的长度方向延伸，当然异形的导轨140也可以仅仅作为一个配合件与设备上的安装槽位配合。值得注意的是，利用导轨140和设备上的凹槽311配合，对于后进出液的方案来说，可以确保液冷光模块的安装位置正确，从而保证液冷壳体100上的冷却液输入口110和冷却液输出口120能够对准设备内部的冷却液循环系统的接头进行安装。
为了方便配合冷却液循环系统，以及光模块的可插拔需求，冷却液输入口110和冷却液输出口120的端部设置有快速连接头(图中未标示)，快速连接头可以使得冷却液流路很方便地接入到冷却液循环系统。快速连接头提供了简单快捷的连接方式，适于多次插拔连接，并且在连接好之后具有一定的密封性能，避免冷却液泄漏。
液冷壳体100的内腔可以根据实际需要设计，此处举出两种结构形式进行说明：
第一种是液冷壳体100的内腔设置有冷却液管道150，冷却液管道150与冷却液输入口110、冷却液输出口120构成冷却液流路。冷却液管道150也可以有多种结构，例如，冷却液管道150在液冷壳体100的内腔中呈盘管状，盘管形状可以是根据实际需要设置，例如仅设置一圈盘管，或者盘管的走向根据发热组件200的发热区域分布，或者沿液冷壳体100的平面设置多圈盘管，或者以立体分布的形式设置多圈盘管等，在此不作限定。通过上述方式能够更加充分地吸收液冷壳体100中的热量，从而实现更好的散热效果，如图3所示。
第二种是液冷壳体100的内腔设置有冷却液腔体，冷却液腔体分别连通冷却液输入口110和冷却液输出口120。这种结构形式是在内腔中直接填充冷却液，并且对液冷壳体100的支撑性能要求不高，因此内腔的形状也可以根据实际需要设置，例如根据发热量大小设置内腔的容积，或者根据发热组件200的发热区域调整内腔的形状，或者在需求更高吸热效率的时候降低内腔的厚度和在内腔设置弯曲的流道等，在此不做限定。通过上述方式同样能够更加充分地吸收液冷壳体100中的热量，从而实现更好的散热效果。
参照图4至图8所示，本申请实施例还提供了一种设备，包括：
液冷光模块，包括发热组件200和液冷壳体100，发热组件200的一端设置有光连接器210，另一端设置有电连接器220，液冷壳体100包括容置部、冷却液输入口110和冷却液输出口120，容置部包裹发热组件200，并设有分别对应光连接器210和电连接器220的开口，冷却液输入口110和冷却液输出口120连通到液冷壳体100的内腔以形成冷却液流路；
设备框架300，包括光模块插槽310和电口连接器320，光模块插槽310被设置为固定液冷光模块，电口连接器320设置在光模块插槽310的末端以对接电连接器220。
本实施例的液冷光模块与前述实施例中的液冷光模块可以采用类似的结构，同样具有发热组件200和液冷壳体100，通过液冷壳体100的容置部安装发热组件200并吸收发热组件 200的热量，通过冷却液循环的方式将吸收的热量释放到外部。本实施例还包括设备框架300，设备框架300中的光模块插槽310用于安装上述液冷光模块，电口连接器320设置在光模块插槽310的末端，用于对接液冷光模块的电连接器220。
在一些实施例中，液冷壳体100的侧面设置有导轨140，光模块插槽310的内侧设置有与导轨140配合的凹槽311。液冷光模块通常是立体矩形，因此光模块插槽310通常是矩形截面的管形结构，在插入液冷光模块时，将液冷光模块侧面的导轨140对准光模块插槽310的内侧的凹槽311进行安装，防止因为安装位置偏移而损伤液冷光模块或者对应的设备。
液冷壳体100包括前端面和后端面，冷却液输入口110和冷却液输出口120均设置在前端面，或冷却液输入口110和冷却液输出口120均设置在后端面。根据冷却液输入口110和冷却液输出口120设置位置的不同，实际上对应了液冷光模块的前进出液方案(图5)和后进出液方案(图4)。值得注意的是，利用导轨140和设备上的凹槽311配合，对于后进出液方案来说，可以确保液冷光模块的安装位置正确，从而保证液冷壳体100上的冷却液输入口110和冷却液输出口120能够对准设备内部的冷却液循环系统的接头(图4中以330标示)进行安装。
参照图6至图7所示，设备框架300为交换机壳体；或者，参照图8所示，设备为机架设备，设备框架300为机架托盘。
设备框架300为交换机壳体的情况下，交换机预先设置了多个光模块插槽310，光模块插槽310被交换机壳体封闭，因此液冷光模块安装到交换机中时，可以根据实际需要采用前进出液方案(图6)，也可以采用后进出液方案(图7)，后进出液方案下，交换机壳体内部可以设置冷却液循环系统的接头。
设备框架300为机架托盘的情况下，机架设备预先设置了多层PCB板，每层PCB板可以设置多个光模块插槽310，光模块插槽310开放式设置，因此机架设备往往采用前进出液的方案(图8)。
当然，应用可插拔光模块的设备的类型有多种，并不限于上述举例提到的交换机和机架设备，其他类型根据实际需要设计光模块插槽310即可，在此不作限定。
综上可知，液冷壳体100包括发热组件200，并在液冷壳体100上设置冷却液输入口110和冷却液输出口120，利用冷却液循环的方式对包裹着的发热组件200进行液冷散热；由于采用液冷壳体100包裹的形式设计光模块，保持了传统光模块的结构特征，因此可以适用于可插拔光模块的盒式设备或者机架式设备，解决了使用大容量光模块场景下，风冷散热能力不足以及沉浸液冷方案的缺陷。
本申请实施例提供的一种液冷光模块及设备，至少具有如下有益效果：通过液冷壳体包括发热组件，并在液冷壳体上设置冷却液输入口和冷却液输出口，利用冷却液循环的方式对包裹着的发热组件进行液冷散热；由于采用液冷壳体包裹的形式设计光模块，保持了传统光模块的结构特征，因此可以适用于可插拔光模块的盒式设备或者机架式设备，解决了使用大容量光模块场景下，风冷散热能力不足以及沉浸液冷方案的缺陷。
以上是对本申请的一些实施进行了说明，但本申请并不局限于上述实施方式，熟悉本领域的技术人员在不违背本申请范围的前提下还可作出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
