具体实施方式
请参照图1至图13所示，其显示出了本发明之多种较佳实施例的具体结构。
首先，请参照图1至图8所示，一种提高换热效率的液冷散热器，包括有VC均热板10、隔液盖20以及壳体30；其中：
所述壳体30具有冷液入口31和热液出口32；
所述VC均热板10安装于壳体30的底部，所述VC均热板10与壳体30之间围构形成容置腔50，所述VC均热板10的上侧表面周缘与壳体30之间夹设有第一密封圈40；
所述隔液盖20罩设于VC均热板10上，所述隔液盖20将容置腔50分隔形成有彼此密闭的冷液腔51和热液腔52，所述冷液入口31和热液出口32分别连通冷液腔51和热液腔52，所述隔液盖20的顶部开设有连通冷液腔51和隔液盖内部23之间的第一槽孔21；所述隔液盖20的周侧底部设置有连通热液腔52和隔液盖内部23之间的第二槽孔22，所述隔液盖20的上侧表面周缘与壳体30之间夹设有第二密封圈60；
冷液经冷液入口31流入冷液腔51，然后经第一槽孔21流入隔液盖内部23，冷液吸收VC均热板10的热量变为热液，热液经隔液盖20周侧底部的第二槽孔22流出并流入热液腔52，热液腔52的热液经热液出口32流出壳体30。
优选地，所述第二槽孔22分别设置于隔液盖20的四周以使隔液盖20的四周排出热液。在实际设计时，所述第二槽孔22为若干密布的小孔或者沿隔液盖20的周边延伸的长形孔（请对比图3和图7所示）。
如图3和图5所示，所述VC均热板10具有向上凸起的凸包11，所述凸包11内设置有真空腔体112，所述真空腔体112的内壁具有毛细结构111，所述毛细结构111可以指一些凸凹纹理。所述隔液盖20罩设于凸包11上，冷液流入隔液盖内部23后，冷液吸收VC均热板10的凸包11表面的热量变为热液。优选地，所述冷液腔51居中设置于VC均热板10的凸包11上方。
通常，所述VC均热板10的底部为平面。所述VC均热板10具有位于凸包11外周的上侧平面12，所述上侧平面12经第一密封圈40与壳体30的底部密封接触，同时，所述上侧平面12与壳体30的底部相定位并通过螺丝70锁固，所述螺丝70的锁固位置处于第一密封圈40的外周。
本实施例中，所述壳体30上方设置有液泵腔301，在壳体30的顶部装设有上盖90用于封住液泵腔301。所述液泵腔301内装设有液泵80，所述液泵腔301的底部具有连通冷液入口31、液泵腔301之间的通孔；冷液从通孔内向上抽吸流入液泵腔301，经液泵的叶轮作用后，冷液从液泵腔301的周侧流出并向下流入隔液盖20的第一槽孔21。通常，所述冷液入口31和热液出口32处于相同液平高度。
在壳体30的底部对应热液腔52设置有条形凹槽，例如：在隔液盖20的四周的三边各布置一条形凹槽，定义为第一条形凹槽201、第二条形凹槽202及第三条形凹槽203，所述第一条形凹槽201沿热液流向衔接贯通于第二条形凹槽202的一端，所述第二条形凹槽202的另一端与第三条形凹槽203的一端共同交汇连通至热液出口32；所述第一条形凹槽201、第二条形凹槽202及第三条形凹槽203的内顶面均为沿热液流向渐高式倾斜设置，以使热液腔52的热液可以经第一条形凹槽201、第二条形凹槽202及第三条形凹槽203导流，热液腔52的截流面积沿热液流向是渐大设置的，也有利于热流的快速流出。
以及，在壳体30的底部两侧分别装设有脚架组件100，便于整个液冷散热器的安装应用。
请参照图9所示，一种液冷散热器系统，包括有液冷排200、连接于液冷排的冷液进液管300和热液出液管400，还包括有上述的提高换热效率的液冷散热器；所述冷液进液管300连接至所述的冷液入口31，所述热液出液管400连接至所述的热液出口32；
冷液进液管300内的冷液经冷液入口31流入壳体30内，冷液吸收VC均热板10的热量变为热液，热液经热液出口32从壳体30流出并经热液出液管400流至液冷排200，液冷排200将热液的热量散发至外界变为冷液，冷液再次流入冷液进液管300形成循环，循环动力由液泵80提供。
接着，请参照图10至图13所示，其显示了另一较佳实施例的具体结构，其主要结构与上述实施例相同，主要区别在于：本实施例中，在壳体30’内未设置液泵，因此，壳体30’的结构相对较为简单。 同样地，图10所示的一种提高换热效率的液冷散热器，也可与液冷排、冷液进液管和热液出液管形成液冷散热器系统，只需在图10所示的一种提高换热效率的液冷散热器的外部设置液泵即可，液泵的设置位置可灵活选择，不作限制。
本发明的设计重点在于，其主要是通过VC均热板的设置，大幅提升液冷散热器的换热效率，实现快速散热，更好地满足产品散热需求，尤其是能够满足急需快速散热的产品的散热效率要求，确保理想的散热效果；
以及，VC均热板与隔液盖以及壳体的结构设计巧妙合理，结合进液、换热、出液整个液体流向，从隔液盖的四周排出热液，确保冷液与VC均热板的凸包表面充分接触、快速换热。

6.根据权利要求3所述的一种提高换热效率的液冷散热器，其特征在于：所述冷液腔居中设置于VC均热板的凸包上方。
7.一种液冷散热器系统，其特征在于：包括有液冷排、连接于液冷排的冷液进液管和热液出液管，还包括有如权利要求1至6中任一项所述的一种提高换热效率的液冷散热器；所述冷液进液管连接至所述冷液入口，所述热液出液管连接至所述热液出口；
冷液进液管内的冷液经冷液入口流入壳体内，冷液吸收VC均热板的热量变为热液，热液经热液出口流出壳体并经热液出液管流至液冷排，液冷排将热液的热量散发至外界变为冷液，冷液再次流入冷液进液管形成循环，循环动力由液泵提供。
