本申请还提供一种服务器散热控制方法，应用于上述任意一项的服务器散热控制装置，包括：
判断箱体上的盖板是否关闭；
若盖板关闭，则判断箱体内压力是否为第一正常值；
若判定所述箱体(10)内压力不为第一正常值，则控制导流驱动件运转，在散热工质朝冷凝盘管流动并通过冷凝盘管冷凝后，空气和液滴状的散热工质经导流驱动件的出口流至气液分离件，气液分离件分离空气和液滴状的散热工质，空气向上排出箱体，以使箱体内的压力调整至第一正常值；
若盖板打开，则判断箱体内压力是否为第二正常值；
若判定所述箱体(10)内压力不为第二正常值，则控制导流驱动件运转，在散热工质朝冷凝盘管流动并通过冷凝盘管冷凝后，空气和液滴状的散热工质经导流驱动件的出口流至气液分离件，气液分离件分离空气和液滴状的散热工质，空气向上排出箱体，以使箱体内的压力调整至第二正常值。
相对于上述背景技术，本申请实施例所提供的服务器散热控制装置，用于供服务器散热，该装置具体包括箱体、盖板、散热工质和冷凝模组，其中，服务器设于箱体中，盖板连接箱体，盖板用于封闭箱体，以提高服务器散热循环的密闭空间；散热工质设于箱体内，服务器浸没于散热工质中，以供服务器散热；冷凝模组设于箱体内。进一步地，冷凝模组具体包括冷凝盘管、导流驱动件和气液分离件，冷凝盘管设于箱体内，冷凝盘管用于辅助散热工质相变，以实现散热循环，所谓相变是指蒸发成气体状态的散热工质在冷凝盘管上释放热量后冷凝成液体的过程，冷凝成液体状态的散热工质，在重力作用下，回落至箱体内，从而实现散热循环；导流驱动件朝向冷凝盘管设置，导流驱动件用于提供驱动力控制蒸汽/气体状的散热工质向冷凝盘管流动；气液分离件设于导流驱动件的出口处，气液分离件用于分离空气和液滴状的散热工质。这样可以带来以下有益效果：
其一，气态的散热工质在冷凝盘管上充分冷凝，从而提高冷凝效率；
其二，可实现在盖板关闭时防止气态的散热工质冲击盖板，由于散热工质冲击盖板再反弹流向冷凝模组会增加压损，相当于增加蒸汽的温降，间接的降低了冷凝效率，因此，可防止气态的散热工质冲击盖板，从而可进一步提高冷凝效率；
其三，可实现在盖板打开时防止气态的散热工质泄露至箱体的外部，也就是说，通过导流驱动件改变散热工质的流动方向，以防止散热工质泄露至箱体的外部；
其四，本申请实施例在设置冷凝盘管和导流驱动件的基础上，通过导流驱动件实现对于氟化液蒸汽的导流驱动，从而使导流过来的氟化液蒸汽在冷凝盘管上完全冷凝，导流驱动件出口位置主要为氟化液小颗粒液滴和少量的空气，导流驱动件的出口设置有气液分离件，由于气体和液体的密度不同，混流遇到阻碍时，气体会折流而走，液体由于惯性会有一个继续向前的速度，向前的液体附着在气液分离件上，并因重力的作用向下汇集到一起，最后滴回至箱体内部；而空气由于密度小会折流向上，通过箱体顶部排向箱体外部，从而可以使箱体内的压力始终维持在正常值，有利于保证系统运行的稳定性。
此外，本申请实施例所提供的服务器散热控制方法，应用于上述服务器散热控制装置，包括判断箱体上的盖板是否关闭，若盖板关闭，则判断箱体内压力是否为第一正常值，若箱体内压力不是第一正常值，则控制导流驱动件运转，在散热工质朝冷凝盘管流动并通过冷凝 盘管冷凝后，空气和液滴状的散热工质经导流驱动件的出口流至气液分离件，气液分离件分离空气和液滴状的散热工质，空气向上排出箱体，以使箱体内的压力调整至第一正常值；若盖板打开，则判断箱体内压力是否为第二正常值，若箱体内压力不是第二正常值，则控制导流驱动件运转，在散热工质朝冷凝盘管流动并通过冷凝盘管冷凝后，空气和液滴状的散热工质经导流驱动件的出口流至气液分离件，气液分离件分离空气和液滴状的散热工质，空气向上排出箱体，以使箱体内的压力调整至第二正常值。上述设置方式可以维持箱体内压力为正常值，从而提升服务器的散热效率。
相较于传统服务器散热，本申请实施例提供的服务器散热控制装置和方法，能够提高冷凝效率，从而提升散热效率，与此同时，能解决箱体开盖维护服务器时泄露氟化液，这样不仅可以降低氟化液的损失，还可以解决泄露氟化液带来的潜在安全风险问题，从而提高安全性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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其他实施例，属于本申请保护的范围。
本申请的核心是提供一种服务器散热控制装置以及应用于该服务器散热控制装置的服务器散热控制方法，能够提高散热效率，并解决箱体开盖维护服务器时泄露氟化液的损失和潜在的安全风险问题。
为了使本技术领域的技术人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。
需要说明的是，下文所述的“上端、下端、左侧、右侧”等方位词都是基于说明书附图所定义的。
请参考图1至图8，图1为本申请实施例中服务器散热控制装置未开盖的整体结构示意图；图2为图1所示服务器散热控制装置的侧视图；图3为图2所示服务器散热控制装置的散热示意图；图4为图2中冷凝模组的结构示意图；图5为图1所示服务器散热控制装置的俯视图；图6为图1所示服务器散热控制装置的正视图；图7为本申请实施例中服务器散热控制装置开盖后的整体结构示意图；图8为本申请实施例中服务器散热控制方法的流程图。
本申请实施例所提供的服务器散热控制装置1，用于供服务器103散热，该装置具体包括箱体10、盖板11、散热工质101和冷凝模组102，其中，服务器103设于箱体10中，盖板11连接箱体10，盖板11用于封闭箱体10，以提高服务器103散热循环的密闭空间；散热工质101设于箱体10内，服务器103浸没于散热工质101中，以供服务器103散热；冷凝模组102设于箱体10内，冷凝模组102用于提供冷凝工况，以便气体状态的散热工质101释放热量后冷凝成液体。
在一些实施例中，上述散热工质101可以采用氟化液。
进一步地，冷凝模组102具体包括冷凝盘管1021和导流驱动件1022。其中，冷凝盘管1021设于箱体10内，冷凝盘管1021用于辅助散热工质101相变，以实现散热循环，需要说明的是，所谓相变是指蒸发成气体状态的散热工质101在冷凝盘管1021上释放热量后冷 凝成液体的过程；冷凝成液体状态的散热工质101，在重力作用下，回落至箱体10内，从而实现散热循环；导流驱动件1022朝向冷凝盘管1021设置，导流驱动件1022用于提供驱动力控制蒸汽/气体状的散热工质101向冷凝盘管1021流动。
这样一来，上述设置方式可带来诸多有益效果，具体包括：其一，气态的散热工质101可以在冷凝盘管1021上充分冷凝，从而大大提高冷凝效率；其二，可实现在盖板11关闭时防止气态的散热工质101冲击盖板11，由于散热工质101冲击盖板11再反弹流向冷凝模组102会增加压损，相当于增加蒸汽的温降，间接的降低了冷凝效率，因此，可防止气态的散热工质101冲击盖板11，从而可进一步提高冷凝效率；其三，可实现在盖板11打开时防止气态的散热工质101泄露至箱体10的外部，也就是说，通过导流驱动件1022改变散热工质101的流动方向，以防止散热工质101泄露至箱体10的外部。
相较于传统服务器103散热，本申请实施例提供的服务器散热控制装置1，能够提高冷凝效率，从而提升散热效率，与此同时，能解决箱体10开盖维护服务器103时泄露氟化液，这样不仅可以降低氟化液的损失，还可以解决泄露氟化液带来的潜在安全风险问题，从而提高安全性。
当然，根据实际需要，上述导流驱动件1022具体可以设置为贯流风扇、轴流风扇等。根据本申请的应用场景，本申请在一些实施例中采用贯流风扇。
可以理解的是，在不设置贯流风扇的情况下，氟化液气体流动的驱动力来源于服务器103上部蒸发区正压和冷凝区负压的压差，考虑到泄露问题，箱体10内部为常压控制，压差不能太大，如此一来，蒸汽在箱体10内部上升过程中大部分会冲击盖板11，然后再反弹流向冷凝模组102，这样会增加压损，相当于增加了蒸汽的温降，间接的降低了冷凝效率。当箱体10需要开盖维护时这个问题会导致氟化液气体径直流向箱体10外部，进而导致价格昂贵的氟化液的大量流失，不仅造成经济损失还造成安全隐患。
通过本申请提出的两相浸没液冷服务器散热控制装置1，在冷凝模组102的设置下，正常运行时，通过贯流风扇的抽力提供蒸汽流动的主要驱动力，避免蒸汽径直向上冲击盖板11再反弹降低蒸汽冲击和反弹时的局部损失，同时在冷凝区维持相同压力的情况下，可以降低蒸发区的压力，也即降低了氟化液的沸点，最终降低服务器103内部芯片的温度。如果维持相同的芯片温度，则可以提高芯片的热流密度，即实现了更高的解热密度。
也就是说，上述设置方式可以从根本上解决箱体10开盖维护时氟化液蒸汽大量流失的问题，同时还可以大幅提升冷凝器的冷凝效率，实现更高解热密度，降低了单位功耗的散热设备成本。
在一些实施例中，导流驱动件1022设于靠近冷凝盘管1021的入口一侧。
当箱体10处于开盖维护时，通过调整贯流风扇的运转速度控制箱体10内的压力，达到箱体10内外气压平衡，从而避免蒸汽泄露到箱体10外部。此时，贯流风扇布置在冷凝盘管1021的入口一侧或附近，由于此处冷凝能力最强，因此，贯流风扇抽吸过来的氟化液蒸汽在冷凝模组102内完全冷凝，从而大大提高冷凝效率。
在一些实施例中，冷凝盘管1021与箱体10的侧壁形成有容纳空间，导流驱动件1022设于容纳空间内，且冷凝盘管1021在服务器103的布设方向上覆盖导流驱动件1022。
也就是说，导流驱动件1022设于冷凝盘管1021与箱体10的侧壁之间，由于服务器103一般沿竖向布设于箱体10中，因此，冷凝盘管1021在竖直方向上覆盖导流驱动件1022，这样可以保证箱体10内的冷凝区域足够大，且导流驱动件1022被覆盖在冷凝区域内。
在一些实施例中，冷凝盘管1021具体为截面形状为S型的盘管。
具体地说，该冷凝盘管1021的入口连接位于箱体10外部的冷凝管道的一端，该冷凝管道设有泵、压缩机等制冷组件，冷凝盘管1021的出口连接位于箱体10外部的冷凝管道的另一端，如此一来，即可实现制冷循环。S型盘管的结构可以增加冷凝的面积，从而大大提高箱体10内的冷凝效率。
以冷凝模组102布置在单侧为例，系统投入后，氟化液吸收服务器103的发热量，并在液体达到饱和温度时蒸发成氟化液气体，在冷凝盘管1021上释放热量冷凝成液体，并在重力作用下回落至箱体10内部，如此实现散热循环。当然，根据实际需要，冷凝模组102布置也可以布设于服务器103的两侧。
为了保证保证系统运行的稳定性，冷凝模组102还包括气液分离件1023，气液分离件1023设于导流驱动件1022的出口处，气液分离件1023用于分离空气和液滴状的散热工质101。在一些实施例中，气液分离件1023包括第一折流板10231和第二折流板10232，第一折流板10231连接导流驱动件1022的出口壳体，第二折流板10232连接第一折流板10231并与第一折流板10231呈预设夹角设置。该预设夹角的范围可以根据贯流风扇出口角度进行调整，预设夹角的范围一般为大于90°。
这样一来，本申请在设置冷凝盘管1021和贯流风扇的基础上，通过气液分离件1023实现气液分离。具体地，贯流风扇抽吸过来的氟化液蒸汽在冷凝模组102上完全冷凝，在贯流风扇的驱动作用下，氟化液小颗粒液滴和少量的空气由风扇靠近冷凝盘管1021的一侧进入风扇，然后氟化液小颗粒液滴和少量的空气在风扇叶片的驱动作用下沿风扇底部的出口流 出，风扇底部的出口为贯通孔，也即贯流风扇出口位置主要为氟化液小颗粒液滴和少量的空气，贯流风扇出口设置有一定角度的折流板，利用折流分离原理，即由于气体和液体的密度不同，混流遇到阻碍时，气体会折流而走，液体由于惯性会有一个继续向前的速度，向前的液体附着在折流板阻挡壁面上，并因重力的作用向下汇集到一起，最后在第二折流板10232的底部滴回至箱体10内部；而空气由于密度小会折流向上，通过箱体10顶部排向箱体10外部，从而可以使箱体10内的压力始终维持在正常值，有利于保证系统运行的稳定性。
在一些实施例中，为了便于排出空气，服务器散热控制装置1还包括透气阀12，透气阀12设于盖板11的底部，气液分离件1023分离出的空气经透气阀12排出箱体10。
在一些实施例中，服务器散热控制装置1还包括压力检测组件和控制组件，其中，压力检测组件设于箱体10内，压力检测组件用于检测箱体10内的压力；控制组件连接压力检测组件和导流驱动件1022，控制组件用于根据压力检测组件检测的压力值控制导流驱动件1022工作。该控制组件可以为PLC。
具体地，压力检测组件可以包括第一压力传感器15和第二压力传感器16，第一压力传感器15设于盖板11和箱体10之间或者盖板11上，并用于检测盖板11处于闭合还是开启状态，第二压力传感器16设于盖板11的底部，并用于检测箱体10内压力值；此外，箱体10内部还布置有液位计及温度传感器17。
在一些实施例中，服务器散热控制装置1还包括调压阀，调压阀设于盖板11上并连接控制组件，调压阀用于调节箱体10内的压力，比如可以在盖板11底部布置电磁阀13，通过控制组件控制电磁阀13实现箱体10内的压力调节。当然，还可以在盖板11底部布置机械式安全阀(机械泄压阀14)。
此外，本申请实施例所提供的服务器散热控制方法，应用于上述服务器散热控制装置1，包括：
S1：判断箱体10上的盖板11是否关闭；
S2：若盖板11关闭，则判断箱体10内压力是否为第一正常值，若箱体10内压力不是第一正常值，则控制导流驱动件1022运转，在散热工质101朝冷凝盘管1021流动并通过冷凝盘管1021冷凝后，空气和液滴状的散热工质101经导流驱动件1022的出口流至气液分离件1023，气液分离件1023分离空气和液滴状的散热工质101，空气向上排出箱体10，以使箱体10内的压力调整至第一正常值；
S3：若盖板11打开，则判断箱体10内压力是否为第二正常值，若箱体10内压力不是第二正常值，则控制导流驱动件1022运转，在散热工质101朝冷凝盘管1021流动并通过冷 凝盘管1021冷凝后，空气和液滴状的散热工质101经导流驱动件1022的出口流至气液分离件1023，气液分离件1023分离空气和液滴状的散热工质101，空气向上排出箱体10，以使箱体10内的压力调整至第二正常值。
上述设置方式可以维持箱体10内压力为正常值，从而提升服务器103的散热效率。
在一些实施例中，本申请实施例所提供的服务器散热控制方法具体包括：
系统正常启动；
获取第一压力传感器15的数据；
根据第一压力传感器15检测到的数据判断盖板11是否关闭；
若盖板11关闭，则获取第二压力传感器16的数据，并根据第二压力传感器16的数据判断箱体10内压力是否为第一正常值，若箱体10内压力不是第一正常值，则通过控制导流驱动件1022，和/或调压阀以使箱体10内的压力调整至第一正常值；
若盖板11打开，则获取第二压力传感器16的数据，并根据第二压力传感器16的数据判断箱体10内压力是否为第二正常值；若箱体10内压力不是第二正常值，则通过控制导流驱动件1022以使箱体10内的压力调整至第二正常值。
需要注意的是，上述第一正常值和第二正常值的绝对值不同。
当然，在上述系统正常启动的步骤之前，还包括检测箱体10内的液位计、温度传感器的数值是否正常，若否，则需要进行调整，直至液位计、温度传感器的数值均处于正常值。
需要说明的是，在本说明书中，诸如第一和第二之类的关系术语仅仅用来将一个实体与另外几个实体区分开来，而不一定要求或者暗示这些实体之间存在任何这种实际的关系或者顺序。
