- the above-mentioned device nodes 1031 are connected in series and arranged in the immersion heat exchange cavity 103 in order from low to high temperature specifications.
- the CXL storage node is connected to the liquid distributor, on the one hand, because the temperature specification of the CXL storage device in the CXL storage node is the lowest, and on the other hand, because the structural form of the DIMM strip of the CXL storage device naturally has a uniform flow function, which can play a role in uniform flow of the coolant.

- the flow homogenizer 1023 includes a plurality of flow channels of equal length and equal diameter.
- the coolant enters the liquid cavity 1022 after passing through the liquid collecting pipe 1021, and the flow rate of the coolant can be instantly reduced to a state close to the static state. Then, the coolant with a flow rate close to the static state flows into the flow channel of the immersed heat exchange cavity 103 through the flow channel of the flow homogenizer 1023, and its local resistance loss coefficient is a constant. In this way, the flow rate of any flow channel of the flow homogenizer 1023 is consistent, and the resistance of the liquid inlet and the liquid outlet of any flow channel is consistent, so that the situation of poor heat dissipation effect caused by excessive flow rate of the coolant will not occur.
- a one-way guide plate opened toward the flow channel outlet of the liquid separator 101 is provided at the flow channel inlet of the liquid separator 101, which can ensure that the coolant can smoothly enter the immersion heat exchange cavity 103 on the one hand, and prevent the coolant in the flow channel from flowing back on the other hand.

- BB', CC', DD', EE' and FF' are the flow channels of the homogenizer, and the structure of the liquid distributor 101 is similar to that of the liquid collector 102 shown in Figure 7, so it will not be repeated here.
- the length of the flow channel and/or the diameter of the flow channel are determined by the heat dissipation requirements of the equipment unit through which the coolant flows. It should be understood that whether it is the flow channel of the liquid separator 101, the flow channel of the liquid collector 102, or the flow channel of the immersion heat exchange cavity 103, the length or diameter of the flow channel in the same structural unit (i.e., the liquid separator 101, the liquid collector 102 or the immersion heat exchange cavity 103) may be the same or different, that is, those skilled in the art can set the flow channel to a straight or non-straight shape according to actual conditions to change the length of the flow channel.
- the working energy consumption and temperature specifications of different equipment nodes are different, so the length of the flow channel at the equipment node with higher temperature specifications and greater working energy consumption can be appropriately increased to improve the heat dissipation efficiency and enhance the cooling effect; similarly, the diameter of the flow channel at the equipment node with higher temperature specifications and greater working energy consumption can be increased to increase the flow rate of the coolant at the equipment node and thus improve the heat dissipation efficiency.
- those skilled in the art can determine the length and diameter of the flow channel between different equipment units in the same equipment node according to the actual application scenario. It should be noted that no matter how the flow channel diameter in the immersion heat exchange cavity 103 is changed, the tightness of the connection between the flow channel and the flow channel of the liquid distributor 101/liquid collector 102 should be ensured to ensure that no leakage of the coolant occurs.

- the flow equalizer 1023 and the liquid cavity 1022 are set to a detachable connection structure, which facilitates the cleaning of the flow channels of the liquid separator 101 and the flow equalizer 1023, thereby avoiding the situation where the coolant cannot smoothly enter/flow out of the immersion heat exchange cavity 103 due to blockage of the liquid cavity 1022 or the flow channel.
- the cross-sectional shape of the side where the flow equalizer 1023 is connected to the immersion heat exchange cavity 103 is not unique, that is, the side shape of the flow equalizer 1023 is not limited, and those skilled in the art can determine the side shape of the immersion heat exchange cavity 103.

- the arc-shaped concave surface of the flow homogenizer 1023 of the liquid separator 101 is concave toward the side of the liquid collecting pipe 1021 of the liquid separator 101 , which has the beneficial effect of reducing the resistance to the coolant and increasing the rate at which the coolant flows into the liquid separator 101 .
- the side of the flow equalizer 1023 away from the liquid chamber 1022 is in a semicircular arc shape, and the arc-shaped concave surface of the flow equalizer 1023 is concave toward the side of the collecting pipe 1021; it should be understood that the side of the flow equalizer 1023 away from the liquid chamber 1022 is the side of the flow equalizer 1023 close to the immersion heat exchange chamber 103, that is, the side of the flow equalizer 1023 connected to the immersion heat exchange chamber to deliver the coolant into the flow channel in the immersion heat exchange chamber; setting the side of the flow equalizer 1023 away from the liquid chamber 1022 to a semicircular arc shape can reduce the resistance to the coolant on the one hand, so that the coolant can flow into the flow channel of the immersion heat exchange chamber more quickly and smoothly; it should be understood that in actual application scenarios, the two sides of the immersion heat exchange chamber are concave, that is, there is no situation where the immersion heat exchange chamber is incompatible with the liquid separator 101
- liquid separator 101/liquid collector 102 it is not necessary for the liquid separator 101/liquid collector 102 to be tightly connected to the immersion heat exchange cavity.

Description
本申请要求于2022年12月22日提交中国专利局、申请号为202211654933.3、发明名称为“浸没液冷系统、方法和服务器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及液冷技术领域，特别是涉及一种浸没液冷系统、方法和服务器。
主流液冷散热方式主要包括冷板液冷散热和浸没液冷散热，浸没液冷散热是将服务器直接浸没在绝缘的冷却液中，依靠冷却液的循环流动带走服务器运行产生的热量，相对于冷板式液冷散热，噪音更低，更加节能。
目前常用的浸没液冷机柜为长*宽*高约2600*1000*1300mm的浸没换热腔体，液体从长度方向一侧底部流入，流经立式垂直并联布置的液冷服务器带走热量后，从长度方向另外一侧的顶部溢流流出。然而，整个浸没换热腔体长度方向设备节点并联数量高达54个，在占腔体流阻比例最大的底部流程方向上离入口最近的设备节点流程最多只有44.45mm左右，离入口最远的设备节点有2500mm左右；即使从长度方向的两侧同时进液，底部流程方向上离入口最近的设备节点流程只有44.45mm，但是离入口最远的设备节点仍有1250mm左右，依然相差了两个数量级。由此可见，每个设备节点之间的流程相差有两个数量级，即每个设备节点的沿程阻力损失差异两个数量级，如此必然会导致不同流程设备节点的流量差异巨大，且实测过程中发现不同流程设备节点内部的温度迥异。
另外，传统系统架构设计主要考量设备节点的综合竞争力及稳定的产品性能。而云原生系统架构设计基于数据中心整体维度的计算、存储、输入/输出、加速单元解耦，强调各类功能单元基于特定应用的极简设计，即单设备节点聚焦计算、存储、输入/输出或者加速单元。这样一来，不同设备节点的功耗大小和部件温度规格差异很大，而温度相同的入口流量，无法满足不同设备节点的差异化的温度流量需求。
现有技术中，为了解决上述技术问题，采用的常规的技术手段为：在浸没换热腔体底部增设匀流板，以在一定程度上消除流量差异，但是由于不同流程设备节点底部入口沿程阻力损失相差两个数量级，实际应用中往往与设计差异巨大，为了提高远程设备节点内部的流量，只能通过增加循环泵流量来实现，但是如此一来就增加了系统功耗，拉高了系统能源效率(PUE，所述PUE＝数据中心消耗的所有能源与IT负载使用的能源之比)，与现在要求的绿色节能理念相悖。并且，采用常规的技术手段无法同时满足相同设备节点完全一样的流量的需求，即，不同设备节点间因功耗不同、温度规格不一而产生的差异化的流量需求。

为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请提供的浸没液冷系统，如图1所示，所述系统应用于如图2所示的浸没换热腔体，所述系统包括：
设置在所述浸没换热腔体103两侧的分液器101和汇液器102；
所述分液器101、所述汇液器102和所述浸没换热腔体103均设置有流道，经所述分液器101的流道分流的冷却液，沿浸没换热腔体103的流道，从所述汇液器102的流道流出形成液冷流道。
具体地，如图1所示，所述分液器101设置于所述浸没换热腔体103的左侧，所述汇液器102设置于所述浸没换热腔体103的右侧。
在其中一个实施例中，所述浸没换热腔体103如图2所示，所述浸没换热腔体103包括按照温度规格从低到高的顺序依次横向串联连接的至少两个设备节点1031，温度规格最低的设备节点1031最靠近所述分液器101，温度规格最高的设备节点1031最靠近所述汇液器102，如此一来，将冷却液一次送入分液器101即可实现对多个不同的设备节点1031的散热，减少资源消耗，提高散热效率。
具体地，如图2所示，所述浸没换热腔体103包括依次串联连接的CXL存储节点、高密计算节点和输入/输出节点，其中CXL存储节点的温度规格为85℃、高密计算节点的温度规格为100℃、输入/输出节点的温度规格为120℃，按照温度规格从低到高的顺序依次将上述设备节点1031串联连接设置于浸没换热腔体103内，只需保证送入分液器101的冷却液温度低于温度规格最低的设备节点1031的温度要求，即可实现对浸没换热腔体103内的设备节点1031进行散热降温。其中在上述由CXL存储节点、高密计算节点和输入/输出节点构成的浸没换热腔体中，将所述CXL存储节点与分液器连接，一方面是因为CXL存储节点内CXL存储设备的温度规格最低，另外一方面是因为CXL存储设备DIMM条的结构形态天然具有匀流功能，能够对冷却液起到匀流的作用。需要理解的是，在实际的应用场景中，所述设备节点1031的流道的流向并不做限定，如图3所示，在同一浸没换热腔体103中设备节点1031的流道可以包括横向设置的，还可以包括竖向设置的，当流道的流向发生变化时，只需在流道流向发生变化前的设备节点1031的出液口设置汇液器102，在流道流向发生变化的设备节点1031的进液口处设置分液器101，使得从汇液器102流出的冷却液可以顺利流入分液器101内，分液器101的流道与设备节点1031的流道连通即可。
在其中一个实施例中，每个所述设备节点1031包括数个并联设置的设备单元10311，相邻的设备单元10311之间设置有流道，通过在浸没换热腔体103内设置多个流道，实现对浸没换热腔体103的冷却降温，以达到提高散热效果的作用。
在其中一个实施例中，当所述相邻的设备节点10311中的前一设备节点10311的流道为多个，后一设备节点10311的流道为多个时，如图5所示，所述系统还包括：在相邻的设备节点10311中的前一设备节点1031的流道出口处设置所述汇液器102，和，在相邻的设备节点10311中的后一设备节点1031的流道入口处设置所述分液器101。在浸没换热腔体103中的CXL存储节点的流道出口设置汇液器102，在与CXL存储节点串联连接的高密计算节点的流道入口处设置分液器101；在相邻的设备节点10311的前一设备节点1031的流道出口处设置所述汇液器102，其作用在于，可以对任一设备节点不同流道内的冷却液达到均温的效果；也就是说，在实际的应用场景中，同一设备节点10311中不同设备单元10311的实际温度存在差异是很常见的，当不同设备单元10311的实际温度存在差异时，设备节点中的各流道内的冷却液的温度也会不一样，通过在设备节点1031的流道出口出设置汇液器102，将设备节点1031中任一流道内的冷却液在汇液器102的液腔1022中混合，以达到精确控制冷却液温度的有益效果，避免因直接将温度较高的冷却液直接输入至下一设备节点的流道而造成损坏下一设备节点的设备单元的情况的发生。在相邻的设备节点10311中的后一设备节点1031的流道入口处设置所述分液器101，其作用在于，将经汇液器102均温后的冷却液重新匀流，流入后一设备节点的流道内。需要理解的是，当前一设备节点10311和后一设备节点10311的流道均为多个时，所述后一设备节点10311的流道数与后一设备节点10311的流道数不必然是完全相等的。
在其中一个实施例中，当相邻的设备节点10311中的前一设备节点10311的流道为多个，后一设备节点10311的流道为单个时，如图4所示，所述系统包括：在相邻的设备节点10311中的前一设备节点1031的流道出口处设置所述汇液器102，将所述汇液器102的集液管1021与后一设备节点1031的流道连通；前一设备节点1031的流道内的冷却液在汇液器102的液腔均温后，沿所述汇液器102的集液管1021流入后一设备节点1031的流道中。
在其中一个实施例中，当相邻的设备节点10311中前一设备节点10311的流道为单个，后一设备节点10311的流道为多个时，如图6所示，所述系统包括：在相邻的设备节点10311中的后一设备节点1031的流道入口处设置所述分液器101，将所述分液器101的集液管1021与前一设备节点1031的流道连通，前一设备节点1031流道内的冷却液经所述分液器101匀流后，流入后一设备节点1031的流道中。
基于上述浸没液冷系统，能够提升散热效率，减少资源消耗，能够协调同一设备节点1031间与不同温度规格设备节点1031间的差异化流量需求。
在其中一个实施例中，所述系统还包括：热交换器104；所述热交换器104连通所述汇液器102与所述分液器101，从所述汇液器102流出的冷却液，经所述热交换器104冷却后，重新经所述分液器101流入所述浸没换热腔体103形成液冷循环，将从汇液器102流出的冷却液送入热交换器104进行冷却降温，再将冷却降温后的冷却液重新送入分液器101对浸没换热腔体103内的设备节点1031/设备单元10311进行散热降温，形成液冷循环，提高了资源的利用率，具有绿色节能的有益效果。
在其中一个实施例中，所述分液器101包括集液管1021、液腔1022和匀流器1023；所述匀流器1023内设置有流道，冷却液依次经所述集液管1021和所述液腔1022，沿所述匀流器1023的流道流入所述浸没换热腔体103；在匀流器1023内部设置流道对送入分液器101内的冷却液进行分流，便于将冷却液送入与分液器101的流道连通的浸没换热腔体103的流
道中。所述分液器101包括集液管1021、液腔1022和匀流器1023，匀流器1023包括若干条等长等径的流道，冷却液经过集液管1021后进入液腔1022，可以将冷却液的流速瞬间降低至接近静止状态，然后将流速接近于静止状态的冷却液通过匀流器1023的流道流入浸没换热腔体103的流道中，其局部阻力损失系数为常数，如此一来，匀流器1023的任一流道的流速一致，且任一流道的进液口和出液口的阻力一致，就不会造成因冷却液流速过快而导致散热效果不佳的情况的发生。
在其中一个实施例中，所述分液器101的流道入口处设置有朝所述分液器101的流道出口一侧开启的单向导流片，一方面能够确保冷却液顺利进入浸没换热腔体103内，另外一方面能够防止流道内的冷却液回流。
在其中一个实施例中，如图7所示，所述汇液器102包括集液管1021、液腔1022和匀流器1023；所述匀流器1023内设置有流道，冷却液依次经所述匀流器1023的流道、液腔1022和集液管1021流出所述浸没换热腔体103。
在其中一个实施例中，所述汇液器102的流道入口处设置有朝所述汇液器102的流道出口一侧开启的单向导流片，一方面有助于浸没换热腔体103的流道内的冷却液流出浸没换热腔体103，另一方面避免因冷却液回流而对浸没换热腔体103内的设备节点1031造成损坏。如图7所示，其中BB’、CC’、DD’、EE’和FF’即为匀液器的流道，所述分液器101的结构与如图7所示的汇液器102的结构类似，故此处不再赘述。
在其中一个实施例中，所述流道的长度，和/或，所述流道的直径由所述冷却液流经的设备单元的散热需求确定。需要理解的是，无论是分液器101的流道，还是汇液器102的流道，又或者是浸没换热腔体103的流道，同一结构单元(即分液器101、汇液器102或浸没换热腔体103)内的流道的长度或直径可以相同也可以不相同，即本领域技术人员可以根据实际情况将流道设置为直线或非直线的形状，以改变流道的长度。具体而言，比如在一个实际情况中，不同设备节点的工作能耗和温度规格不同，因此可适当增长温度规格较高、工作能耗较大的设备节点处的流道长度，以提高散热效率，提升冷却效果；同样地，还可以通过增大温度规格较高、工作能耗较大的设备节点处的流道的直径，以达到增加该设备节点处冷却液流量进而提升散热效率的有益效果。更进一步地，基于上述思想，本领域技术人员可以根据实际应用场景，确定同一设备节点内不同设备单元之间的流道的长度和直径。需要注意的是，无论浸没换热腔体103内的流道直径如何改变，都应确保所述流道与分液器101/汇液器102的流道的连通的紧密性，以确保不会发生冷却液的泄露。
在其中一个实施例中，所述分液器101的流道与所述浸没换热腔体103的至少一个流道连通，以提升对设备单元10311的散热效率；所述汇液器102的流道与所述浸没换热腔体103的每一流道连通，以确保任一流道中的冷却液都可以顺利流出，进而避免因冷却液无法流出而造成的设备节点1031无法散热发生损坏的情况的发生。
在其中一个实施例中，所述液腔1022为半圆弧形中空壳体，所述匀流器1023与所述液腔1022可拆卸式连接，将所述匀流器1023与所述液腔1022设置为可拆卸连接的结构，便于对分液器101和匀流器1023的流道进行清理，避免因液腔1022或流道堵塞而造成冷却液无法顺利进入/流出浸没换热腔体103的情况的发生。
在其中一个实施例中，所述匀流器1023与浸没换热腔体103连接的一侧的截面形状不唯一，即对匀流器1023的侧面形状不作限定，本领域技术人员可以根据浸没换热腔体103的侧
面形状或其他实际情况将匀流器1023的侧面设置为如图9所示的三角形、菱形、六边形、梯形、矩形、平行四边形或任意多边形的形状，无论是哪种形状，只需保证匀流器1023的流道与浸没换热腔体103内的流道紧密连通，保证冷却液可以经匀流器1023的流道顺利进入浸没换热腔体103的流道即可。
在其中一个实施例中，如图8所示，所述匀流器1023靠近所述液腔1022的一侧呈半圆弧形，将所述液腔1022的一侧设置为半圆弧形，能够在很大程度上减小对冷却液的流动阻力。
在其中一个实施例中，所述汇液器102的匀流器1023的弧形凸面凸向所述汇液器102的集液管1021一侧，能够减小对冷却液的阻力，提升冷却液流出汇液器102的速率。
在其中一个实施例中，所述分液器101的匀流器1023的弧形凹面凹向所述分液器101的集液管1021一侧，具有减小对冷却液的阻力，提升冷却液流入分液器101的速率的有益效果。
在其中一个实施例中，如图8所示，所述匀流器1023远离所述液腔1022的一侧呈半圆弧形，所述匀流器1023的弧形凹面凹向所述集液管1021一侧；需要理解的是，所述匀流器1023远离所述液腔1022的一侧，即为所述匀流器1023靠近所述浸没换热腔体103的一侧，即匀流器1023与所述浸没换热腔体连接，以将冷却液送入浸没换热腔体内的流道的一侧；将所述匀流器1023远离所述液腔1022的一侧设置为半圆弧形，一方面能够减少对冷却液的阻力，使得冷却液可以更迅速、更顺畅的流入浸没换热腔体的流道内；需要理解的是，在实际的应用场景中，浸没换热腔体的两侧为凹面状，即不存在浸没换热腔体与分液器101/汇液器102不适配的情况。并且，还需要理解的是，在实际的应用场景中，分液器101/汇液器102是否能与浸没换热腔体紧密连接并不是必要的，只需要保证分液器101/汇液器102的流道与浸没换热腔体的流道紧密连通，冷却液可以顺利从分液器101/汇液器102的流道流入所述浸没换热腔体的流道即可。具体地，还可以在靠近浸没换热腔体的匀流器1023的管道的一侧设置喷嘴，使得冷却液经匀流器1023的管道后，从喷嘴流入浸没换热腔体中。
在其中一个实施例中，所述系统还包括循环泵105和阀门106；所述循环泵105连通所述热交换器104与所述分液器101，热交换器104冷却后的冷却液经所述循环泵105加压后泵入所述分液器101；所述阀门106设置于所述循环泵105与所述分液器101之间；通过设置循环泵105加快了送入冷却液至浸没换热腔体103的速率，提升了对浸没换热腔体103的冷却降温的速率。
在一个实施例中，提供了一种浸没液冷方法，所述方法使用上述的浸没液冷系统对浸没换热腔体103进行散热，所述方法包括：
送入冷却液至所述分液器101，冷却液经所述分液器101的流道进入所述浸没换热腔体103的流道吸收所述浸没换热腔体103内的热量，流出所述汇液器102形成液冷流道，实现对浸没换热腔体103的散热。
在其中一个实施例中，所述方法还包括：在汇液器102和分液器101之间设置热交换器104，以实现对从汇液器102流出的冷却液进行冷却，并将冷却后的冷却液重新送入分液器101形成液冷循环。

冷却液的流量的监测。

在其中一个实施例中，所述方法还包括：设置电磁导向阀至所述分液器101的集液管1021，当设置于所述分液器101的集液管1021上的温度监测模块监测到所述冷却液温度超过第一预设值时，则所述电磁导向阀关闭，切断当前液冷流道。
