本说明书实施例提供一种单相浸没液冷系统。
如图1所示，所述单相浸没液冷系统100包括机柜10和液冷装置。机柜10内设置有电子装置11，在本实施方式中，电子装置11为服务器的电子装置，在其它实施方式中，电子装置11可以为交换机、台式电脑或者其它需要冷却的电子装置的电子装置。
液冷装置包括驱动换热装置200、进液管20和出液管30。
机柜10内设置有电子装置11，机柜10的侧壁上开设有进液管固定孔12和出液管固定孔13。
进液管20上设置有进液阀门21，进液管20的一端穿过进液管固定孔12与机柜10内部连通。通过开闭进液阀门21，可以截断进液管20内的液体或者使进液管20内的液体进行流通。
出液管30上设置有出液阀门31，出液管30的一端穿过出液管固定孔13与机柜10内部连通。通过开闭出液阀门31，可以截断出液管30内的液体或者使出液管30内的液 体进行流通。具体地，在本实施方式中，进液管20的伸入机柜10内的端部位于机柜10的中上部，而出液管30的伸入机柜10内的端部位于机柜10的底部或中下部，以便于进入机柜10内的液体吸收电子装置11的热量后，进入出液管30内，将吸收热量的液体导出。
其中，驱动换热装置200包括液体驱动器和热交换器(图未标示)，所述液体驱动器用于驱动液体流动，提供液体流动的动力，具体可以为泵等；所述热交换器用于对液体进行热交换。
使用时，首先，进液管20与驱动换热装置200的出液端连通，出液管30与驱动换热装置200的进液端连通，即进液管20和出液管30分别与驱动换热装置200的两端相连通，以在机柜10、出液管30、驱动换热装置200和进液管20之间形成液体循环回路；然后，再向机柜10内加入冷却液，在机柜10内冷却液达到工作液面后，启动液体驱动器和热交换器，驱动冷却液在机柜10、出液管30、驱动换热装置200和进液管20形成的液体回路内循环，即，冷却液吸收电子装置11产生的热量后，通过出液管30进入热交换器，在热交换器内进行换热冷却后，再通过进液管20进入机柜10内，对电子装置11进行冷却，如此循环，实现对电子装置11的冷却，由于采用了冷却液冷却的方式，大大提高了冷却效果。
特别说明的是，本说明书中的冷却液是一种液体，其具有绝缘、安全、稳定等特性，并且在工作温度区间范围内无相态变化。冷却液具体可以为矿物油、合成油、氟碳化合物等。氟碳化合物主要指以氟取烷代相应碳链氢原子的有机化合物或聚合物，包括全氟烷烃、全氟氨、氢氟醚、全氟酮、氢氟烃等。
在本实施方式中，为了在进液阀门21、出液阀门31发生故障或者损坏时，避免将机柜10内的冷却液排出，将进液阀门21、出液阀门31的位置设置为高于机柜10的工作液面，也就是说，进液阀门21、出液阀门31的位置设置为高于机柜10内的工作液面即可，与管路的形状和摆放位置无关，如图2所示，进液阀门21、出液阀门31分别进液管20和出液管30的竖向管部上，如图1所示，进液阀门21、出液阀门31分别进液管20和出液管30的横向管部上，在其它实施方式中，若进液管20和出液管30有倾斜管部，则可将进液阀门21、出液阀门31分别进液管20和出液管30的倾斜管部上。另外，在不同的实施方式中，也可以将进液阀门21、出液阀门31分别设置在进液管20和出液管30的不同管部上，如将进液阀门21设置在进液管20的横向管部，而将出液阀门31设置在出液管30的竖向管路上，等等，可以根据需要进行设置。
特别说明的是，在本实施例中，“高”、“低”位置关系均是以水平面为参照依据。
工作液面是能满足机柜10内电子装置11正常工作时，机柜10内液体的高度。比如，电子装置11可以在温度40度以下才可正常工作，则工作液面为能够满足温度在40度以下时机柜10内液体的高度。不同的电子装置11正常工作的温度不同，所以，工作液面 也因电子装置11的不同而高度不同。
使用时，向机柜10内加入冷却液，在机柜10内冷却液达到工作液面后，继续加入冷却液，待冷却液的高度大于进液管20和出液管30的最高点后，启动液体驱动器，驱动冷却液在机柜10、出液管30、驱动换热装置200和进液管20形成的液体回路内循环；最后，将机柜10内多余的液体抽出，使得液体的高度位于工作液面即可。通过加入的冷却液的高度大于进液管20和出液管30的最高点，且在液体驱动器启动后，将多余的冷却液抽出，可以保证在液体驱动器启动前，进液管20和出液管30内充满液体，避免液体驱动器吸收空气而空转，导致液体驱动器损坏。
在进液阀门21、出液阀门31发生故障或者损坏时，关闭液体驱动器，由于进液阀门21、出液阀门31的位置高于机柜10的工作液面，因此，在液体驱动器关闭后，冷却液回落，从而使得进液阀门21、出液阀门31内无冷却液，可直接对进液阀门21、出液阀门31进行维修和更换，相对于将液阀门21、出液阀门31的位置设置在低于机柜10的工作液面时，不必将机柜10内的液体抽出，大大减少了维修或者更换的时间，降低对业务运行的影响。
具体地，为了节省管路在高度方向占用的空间，便于在关闭液体驱动器后，进液阀门21、出液阀门31内的冷却液能够在第一时间回落，将进液阀门21和出液阀门31分别设置在进液管20和出液管30的最高位置，如图1和图3所示，进液阀门21和出液阀门31均是设置在进液管20和出液管30的最高位置。因为，进液阀门21和出液阀门31分别设置在进液管20和出液管30的最高处，在关闭液体驱动器后，进液阀门21、出液阀门31内的冷却液就能够在第一时间回落，操作人员或者维修人员，在液体驱动器的第一时间，便可对进液阀门21和出液阀门31进行维修和更换，而不必等进液管20和出液管30的冷却液完全回落，再进行维修和更换。
继续参见图1，进液管20和出液管30分别包括位于出液管20和进液管30最高位置的横向管部22，进液阀门21和出液阀门31分别设置于进液管20和出液管30的横向管部22上，且进液管20和出液管30的横向管部22分别穿过进液管固定孔12和出液管固定孔13，且进液管固定孔12和出液管固定孔13的位置与进液阀门21和出液阀门31的位置位于同一水平面上。通过将进液阀门21和出液阀门31分别设置于进液管20和出液管30最高位置的横向管部22上，且进液管固定孔12和出液管固定孔13的位置与进液阀门21和出液阀门31的位置位于同一水平面上，从而减少管路的弯折，进而减少冷却液流动的阻力。具体地，在本实施方式中，进液管20和出液管30大致呈为Z字型，在其它实施方式中，可以根据空间要求、使用要求等设置进液管20和出液管30的形状。
在设置进液阀门21和出液阀门31的位置时，若确定会使用某种冷却液，可以根据该冷却液的温度、冷却液的流动速度，计算在机柜10内的电子装置11使用时的工作液面，根据工作液面设置进液阀门21和出液阀门31的位置即可。
而实际中，可能备选的冷却液不止一种，不同的冷却液的特性也不同，冷却温度不同，从而导致冷却液的工作液面不同，如某种冷却液体积随温度变化越大，则体积变化越大，会导致机柜内的液位变化大，温度越高，液位越高；又或者在使用的过程中，会调整冷却液的流动速度，冷却液的流速也不同，也会导致冷却液工作液面高度不同。为了满足上述需求，将进液阀门21、出液阀门31的位置设置为高于机柜10内冷却液的最高工作液面。最高工作液面高于或等于工作液面，是电子装置11工作时，机柜10内的冷却液因温度或者流速等影响能达到的最高液面。
最高工作液面由电子装置的顶板(若电子装置为服务器的时，顶板即为服务器的顶板)的高度、冷却液流速和温度变化对冷却液体积的影响等因素确定。最高工作液面高于或等于电子装置的顶板之上50毫米，同时，最高工作液面还要根据冷却液流速和温度变化对冷却液体积的影响进行高度调整，如冷却液流速比较小，则还需要调高最高工作液面的高度，又如，冷却液体积随温度变化越大，则也需要调高最高工作液面的高度。
在本实施方式中，如图1所示，通过一根进液管20和一根出液管30连通机柜10以及驱动换热装置，在进液阀门21、出液阀门31发生故障或者损坏时，关闭液体驱动器后，冷却液停止循环，不再对机柜10内的电子装置11进行冷却，电子装置11无法继续进行正常工作，电子装置11需要暂停工作，待维修或者更换完毕后，再次启动才可继续进行工作，从而影响了电子装置11的正常工作，比如电子装置11为服务器时，服务器不能正常工作，会影响服务器支持的相关业务的使用或者运行。
基于此，如图4所示，设置两组液冷装置，两个所述液冷装置分别位于所述机柜10的相对两侧，每个液冷装置均通过进液管20和出液管30与机柜10连通，也就是说，在实施例一的基础上增加一组液冷装置。使用时，可以两组液冷装置中的液体驱动器同时开启，使得两组液冷装置中的热交换器均对冷却液进行冷却，也可根据需要，同一时间内只开启一组液冷装置中的液体驱动器，只有该组组液冷装置中的热交换器进行工作，另一组液冷装置备用，在进行工作的液体驱动器、热交换器或者进液阀门21、出液阀门31出现故障时，可启动另一组液冷装置的液体驱动器，使得另一组液冷装置的热交换器进行工作，对冷却液进行冷却，如此，不必暂停电子装置11的正常工作，比如电子装置11为服务器时，服务器能够正常工作，保证服务器业务的正常运行。
具体地，机柜10底部设置有支座14，支座14的数目为多个，用于支撑机柜10。
进一步地，机柜10的数目可以设置为多个，在图5中，以机柜10的数目为两个进行举例说明，为了维持多个机柜10之间的液面平衡，单相浸没液冷系统还包括液面平衡管300，所述液面平衡管300同时与多个机柜10连通，用于维持多个机柜10内的液面平衡，避免因与液体驱动泵的距离不一致而造成的多个机柜10的液面差。
本实施方式通过将进液阀门21、出液阀门31的位置设置为高于机柜10的工作液面，因此，在液体驱动器关闭后，冷却液回落，从而使得进液阀门21、出液阀门31内无冷 却液，可直接对进液阀门21、出液阀门31进行维修和更换，相对于将液阀门21、出液阀门31的位置设置在低于机柜10的工作液面时，不必将机柜10内的液体抽出，大大减少了维修或者更换的时间，降低对业务运行的影响。
在其它实施方式中，也可以将不同时将进液阀门21和出液阀门31的位置都设置为高于机柜10内的冷却液的工作液面，具体地，如图6所示，将进液阀门21的位置都设置为高于机柜10内的冷却液的工作液面，而将出液阀门31的位置都设置为底于机柜10内的冷却液的工作液面。在其它实施方式中，也就是将出液阀门31的位置都设置为高于机柜10内的冷却液的工作液面，而将进液阀门21的位置都设置为底于机柜10内的冷却液的工作液面。即，本说明书的技术只要满足将进液阀门21和出液阀门31中的至少一者的位置设置为高于机柜10内的冷却液的工作液面即可。
通过将进液阀门21、出液阀门31中的至少一者的位置设置为高于机柜10的工作液面，因此，在液体驱动器关闭后，冷却液回落，从而使得进液阀门21、出液阀门31中高于工作液面的阀门内无冷却液，可直接对高于工作液面的阀门进行维修和更换，相对于将液阀门21、出液阀门31的位置设置在低于机柜10的工作液面时，不必将机柜10内的液体抽出，大大减少了维修或者更换的时间，降低对业务运行的影响。
进一步地，如图6所示，在本实施方式中，所述出液管30低于机柜10的工作液面。如图7所示，为了解决在维修过程中，机柜10内的液体继续从出液管30流出，所述出液管30的进液口上设置有可拆卸的出液管封堵头32，出液管封堵头32可拆卸地封堵于出液管30的进液口上。出液管30的进液口位于机柜10，机柜10内的液体从出液管30的进液口进入出液管30内。
对于本实施例中与实施例一中单相浸没液冷系统中结构和功能相同部分，在此不再赘述。
使用时，将出液管封堵头32从出液管30的进液口上拔出，以在机柜10、出液管30、驱动换热装置200和进液管20之间形成液体循环回路；然后，再向机柜10内加入冷却液，在机柜10内冷却液达到工作液面后，启动液体驱动器和热交换器，驱动冷却液在机柜10、出液管30、驱动换热装置200和进液管20形成的液体回路内循环，即，冷却液吸收电子装置11产生的热量后，通过出液管30进入热交换器，在热交换器内进行换热冷却后，再通过进液管20进入机柜10内，对电子装置11进行冷却，如此循环，实现对电子装置11的冷却，由于采用了冷却液冷却的方式，大大提高了冷却效果。
在进液阀门21、出液阀门31发生故障或者损坏时，关闭液体驱动器，由于进液阀门21的位置高于机柜10的工作液面，出液管30的进液口上设置有可拆卸的出液管封堵头32，因此，在液体驱动器关闭后，冷却液回落，且将出液管封堵头32封堵于出液管30的进液口上，从而使得进液阀门21内无冷却液，出液管30也不再有液体流动，可直接对进液阀门21、出液阀门31进行维修和更换，相对于将液阀门21、出液阀门31的位 置设置在低于机柜10的工作液面时，不必将机柜10内的液体抽出，大大减少了维修或者更换的时间，降低对业务运行的影响。
另外，在将进液阀门21、出液阀门31的位置设置为高于机柜10的工作液面时，由于出液管30高于机柜10内的工作液面，出液管30为负压，在出液管30的最高点，工作过程中容易出现空气累积，需要定期排气，影响机柜10内电子装置11的运行。在采用将进液阀门21的位置高于所述机柜10内的冷却液的工作液面，且将出液管30设置为低于机柜10的工作液面，并在出液管30的进液口上设置有可拆卸的出液管封堵头32后，不仅能够便于维修和更换，而且还能够避免出液管30内出现空气累积的技术问题，不需要定期进行排气操作。
在其它实施方式中，如图8所示，在低于机柜10的工作液面的出液管30上设置备用阀门33，也就是说若出液阀门31发生故障或者损坏，可以直接采用备用阀门33完成出液阀门31需要完成的工作，从而不需要对出液阀门31进行更换，也就不会对发生故障或者损坏的出液阀门31进行更换或者维修，进而就不会机柜10内的液体继续从出液管30流出的问题。具体地，在本实施方式中，备用阀门33与出液阀门31并联，在其它实施方式中，备用阀门33与出液阀门31串联，或者同时设置两个备用阀门，一个与出液阀门31并联，一个与出液阀门31串联，具体可以根据需要进行设置，本实施方式不做具体限定。
在其它实施方式中，在进液管20低于机柜10的工作液面时，同样地，可设置于进液阀门21设置并联或者串联的备用阀门。即，直接在进液阀门21和出液阀门31中的其中一者的位置高于机柜10内的冷却液的工作液面时，进液阀门21和出液阀门31中的另一者所在的管路上设置有备用阀门33。
具体地，如图9和图10所示，单相浸没液冷系统100还包括底座14，机柜10的数目为N，其中，N为大于等于2的整数。液冷装置的数目为2个，N个机柜10和2个液冷装置并列固定于底座14上，其中，2个液冷装置位于底座14的中部。
每个液冷装置包括2个驱动换热装置200，2个驱动换热装置200均与对应的进液管20和出液管30，即每个液冷装置内的2个驱动换热装置200同时与该液冷装置的进液管20和出液管30连通，用于对回路内的液体进换热和驱动回路内的液体流动，通过设置2个驱动换热装置200，不仅可以提高换热效率，而且能够增加液体的驱动力，使得距离驱动换热装置200较远的机柜10内的液体也能得到很好的循环，提高冷却效果。
两个液冷装置的进液管20和出液管30分别设置于底座14的相对两侧，并固定于底座14上。
在本实施方式中，由于机柜10数目为N个，且每个机柜10与液体驱动器的距离不一致，导致N个机柜10内的液体出现液面差，影响冷却效果。为了解决因出现液面差导致的影响冷却效果的技术问题，单相浸没液冷系统100还包括液面平衡管300，所述 液面平衡管300同时与多个机柜10连通，用于维持多个机柜10内的液面平衡，从而解决了因出现液面差导致的影响冷却效果的技术问题。
进一步地，如图11所示，单相浸没液冷系统100还包括平衡管封堵头310，平衡管封堵头310可拆卸地封堵于平衡管300上位于机柜10内的管口内。在某个机柜10需要停止检修时，关闭与该机柜10连通的进液管20上的进液阀门21和出液管30上的出液阀门31，同时，将出液管封堵头32封堵于出液管30上位于机柜10内的进液口内，将平衡管封堵头310封堵于平衡管300上位于机柜10内的管口内，即可对机柜10进行停止检修。
进一步地，每个驱动换热装置200的两端分别设置有总进液阀门210和总出液阀门220，在某个驱动换热装置200出现故障时，关闭该驱动换热装置200后，同时关闭总进液阀门210和总出液阀门220，另一个驱动换热装置200可继续进行工作，避免因某一个驱动换热装置200出现不能对机柜10内的电子装置11进行继续冷却，故而影响机柜10内的电子装置11运行。
由于设置有两个液冷装置，在其中一个液冷装置出现故障时，可将该液冷装置关闭，另一个液冷装置继续对电子装置11进行冷却，保证电子装置11的正常工作。另外，正常使用时，可以两个液冷装置同时工作，也可以一个液冷装置工作，另一个液冷装置备用，在机柜10内的电子装置11的温度达到警告值时，启动备用冷却装置，或者在一个液冷装置出现故障时，启动另外一个冷却装置，从而不仅保证电子装置11的正常运行，提高运行效率。
进一步地，为了便于对平衡管300和出液管30进行封堵，在本实施方式中，将平衡管300的管口和出液管30的进液口设置为朝向冷却液的工作液面，便于将平衡管封堵头310封堵于平衡管300的管口内，液管封堵头32封堵于出液管30的进液口内，同时，将进液管20的出液口朝向机柜10的底部。
