具体实施方式
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
为了方便理解，首先将本发明各实施例的主要实现构思进行简单表述。
众所周知，高温是集成电路的大敌，高温不但会导致系统运行不稳，使用寿命缩短，甚至有可能使某些部件烧毁。导致高温的热量不是来自计算机外，而是计算机内部。散热器的作用就是将这些热量吸收，保证计算机部件的温度正常。散热器的种类非常多，CPU、显卡、主板芯片组、硬盘、机箱、电源甚至光驱和内存都会需要散热器，而其中最常接触的就是CPU/GPU的散热器。细分散热方式，可以分为风冷散热器，热管散热器，液冷散热器，半导体制冷散热器，压缩机制冷散热器等等。
液冷散热器是指使用液体在泵的带动下强制循环带走散热器的热量，与风冷相比具有安静、降温稳定、对环境依赖小等优点。液冷散热器的散热性能与其中散热液(水或其他液体)流速成正比，制冷液的流速又与制冷系统水泵功率相关。而且水的热容量大，这就使得液冷制冷系统有着很好的热负载能 力。相当于风冷系统的5倍，导致的直接好处就是CPU/GPU作温度曲线非常平缓。比如，使用风冷散热器的系统在运行CPU/GPU负载较大的程序时会在短时间内出现温度热尖峰，或有可能超出CPU/GPU警戒温度，而液冷散热系统则由于热容量大，热波动相对要小得多。
发明人通过发现如前背景技术所述技术缺陷，进而希望能够寻找到一种方式能够打破传统液冷散热器散热能力瓶颈，使得总散热能力明显提升，且更加节能，噪音更低。基于此，发明人创造性的提出了一种采用外挂水泵及高性能散热模块的用于多热源的液冷散热系统、控制方法及控制装置的技术方案。
为了解决现有技术中存在的现有的液冷散热器中，不管是分体式液冷散热器还是一体式液冷散热器，针对的都是单一负载，当多个负载均对散热需求较高时，则每个负载均需要配置一个液冷散热器，实际使用中当负载功耗高时，系统散热需求升高，因液冷散热器散热能力有限，可能会存在CPU/GPU温度过高产生掉频的现象，当负载功耗低时，系统的散热需求降低，由于多个液冷散热器彼此没有交互关系，存在水泵或者散热风扇持续保持高负荷工作状态，对降低噪音及节约散热资源都不友好的技术问题，本发明的发明人经过创造性的劳动，得到了本发明的一种用于多热源的液冷散热系统、控制方法及控制装置。
本发明的用于多热源的液冷散热系统、控制方法及控制装置针对多热源的液冷散热系统，实现了总散热能力较大提升，并智能调配散热资源，在满足每一路负载散热需求的前提下，更加节能降噪，改善了多负载功耗增加液冷散热器散热能力有限，功耗降低噪音过大和散热资源浪费的问题。
实施例一
图1是本发明实施例一中的一种用于多热源的液冷散热系统的结构示意图。如图1所示，实施例一提供了一种用于多热源的液冷散热系统，用于对多个负载单元进行散热，所述系统包括：至少一个流体泵1、多个换热模块2、流体分配器3以及散热模块4。流体泵1用于驱动流体流动。多个换热模块2用于分别与多个负载单元的热源进行热交换，多个换热模块2分别通过流体 支路并联连接。流体分配器3的输入端与流体泵1的一端相连通，流体分配器3的输出端与多个流体支路的一端连通，流体分配器3用于对流体泵1输出的流体向多个流体支路进行受控分配。以及散热模块4一端与多个流体支路的另一端连通，散热模块4的另一端与流体泵1的另一端相连通，散热模块4用于对流经的流体进行散热；所述系统还包括流体，设置于系统的管路中。
具体的，流体泵1的一端和流体分配器3的输入端相连接，流体分配器3的输出端分别与多个流体支路的一端相连接，多个流体支路的另一端通过管路与至少一个散热模块4的一端相连接，至少一个散热模块4的另一端与流体泵1相连接，从而形成闭环回路；每个流体支路上均设置有换热模块2，换热模块2用于与负载单元的热源进行热交换，从而将负载单元的热量带出后汇聚到所述管路(一个干路)流向散热模块4，进而对流体中携带的热量进行散热；其中，所述水泵可以是外挂水泵，是整体系统的动力源，所述水泵曲线性能优异，可以实现PWM采集及控制；其中，所述流体分配器3的流阻小，通过接收脉冲信号调节流体分配量，单路最小流体分配量不低于20％，最大流体分配量不超过80％，可以调配多负载的散热资源占比；换热模块2采用铜底吸热，细密翅片换热，流道流阻极低，用于吸收热源的热量并输送至散热模块4进行散热；其中，散热模块4可包括散热模块风扇7和冷排，散热模块风扇7可以实现PWM采集及控制，冷排具有多个鳍片，风道合理，性能优异，换热模块2输送的带有热量的冷液经散热模块4散掉；其中，所述流体泵1的数量为一个或多个，可在机箱内布置或机箱外布置，当所述流体泵1位于机箱外时，采用外挂方式安装，当流体泵1的数量为多个时，可采取并联或串联的方式进行连接；其中，所述负载单元可为CPU或GPU等，本发明并不以此为限，任何需要散热的装置均可；当某个负载单元为CPU时，CPU的热源温度可分为封装温度(package)和核心温度(core)，本实施例所说的换热模块2对热源(热源温度)进行热交换，该热源具体可为封装温度或核心温度，也就是说，本实施例的换热模块2可用于对负载单元(为CPU时)的封装温度或核心温度进行热交换；另外，作为另外一个实施例，流体分配 器3的输出端与流体泵1的一端相连通，输入端与多个流体支路的一端连通，即可以反向设置；流体分配器3的输入端可以为一个或多个，而输出端可以为一个或多个，具体数量可以根据用户需求而确定。
基于上述分析可知，通过流体泵1、流体分配器3、换热模块2和散热模块4能够对多个负载单元的热源进行同时散热，从而有效提升了总散热能力，节能效果好，且在满足多热源散热需求的同时，系统噪音更低。
在本实施例中，用于多热源的液冷散热系统还包括控制模块5，分别与所述流体泵1和所述流体分配器3电性连接，用于控制或驱动所述流体泵1和所述流体分配器3受控运行。
