随着技术的发展，设备集成的功能器件越来越多，由此导致这些设备的产热量越来越大，进而影响工作性能。为了避免设备工作时温度过高，相关设备通常配置有散热器，散热器利用其内部工质的蒸发-冷凝循环实现热量的快速传递，最终达到散热的目的。
3DVC(3-Dimension Vapor Chamber，三维蒸汽腔)散热器是一种能够在三维空间进行散热的两相散热器，相比于热管的一维散热及均热板的二维散热，3DVC散热器由于能够在更多维度的空间进行散热，因此具有良好的散热性能。
在实际的散热过程中，工质在蒸发腔内受热蒸发成气态以及在冷凝腔内冷凝成液态，通过工质的蒸发-冷凝循环，实现热量在整个3DVC散热器中的快速传递。但是，在气态的工质向冷凝腔内流动以及液态的工质从冷凝腔向蒸发腔内流动的过程中，气态的工质与液态的工质的流动方向相反，从而会形成剪切力，最终会影响液态的工质和气态的工质的各自流动，降低散热效果。由此可见，相关技术涉及的3DVC散热器仍然存在散热效率不佳的问题。
当然，不局限于3DVC散热器，其它类型的散热器也存在相同的问题。

具体实施方式
为了使本技术领域的人员更好地理解本申请中的技术方案，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作出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
请参考图1至图6，本申请实施例公开一种散热器，所公开的散热器包括基座100、冷凝部200和隔离部300。
基座100为散热器的基部，可以作为散热器的安装连接部。在散热器要安装于待散热对象时，基座100可以与待散热对象进行连接，进而实现散热器与待散热对象之间的装配连接。
当然，基座100不但可以发挥安装连接的作用，而且还可以形成其它结构。在本申请实施例中，基座100设有蒸发腔101、气态工质输出口102和液态工质回流口103。蒸发腔101是液态工质进行蒸发的空间，在蒸发腔101内，液态工质能够蒸发从而形成气态工质。气态工质输出口102和液态工质回流口103均与蒸发腔101连通，蒸发腔101内形成的气态工质会通过气态工质输出口102排出到蒸发腔101之外，进而进行后续的散热工作。在气态工质冷凝后变回液态工质的情况下，这些液态工质最终会通过液态工质回流口103而回到蒸发腔101内，并进入下一次的蒸发-冷凝循环。
隔离部300设有气态工质输入通道105，气态工质输入通道105的第一端部与气态工质输出口102连通。气态工质输出口102输出的气态工质能够通过气态工质输入通道105的第一端部而进入到气态工质输入通道105内。
冷凝部200设于基座100上。具体的，冷凝部200可以固定在基座100上。冷凝部200发挥冷凝作用，冷凝部200通常直接与散热器所处的环境直接接触，因此温度较低。隔离部300设于冷凝部200之内，隔离部300的外 表面与冷凝部200的内壁之间形成液态工质回流通道104。气态工质输入通道105的第二端部与液态工质回流通道104的第一端部连通，液态工质回流通道104的第二端部与液态工质回流口103连通。也就是说，气态工质输出口102、气态工质输入通道105、液态工质回流通道104、液态工质回流口103和蒸发腔101依次连通，从而形成一个工质循环流通结构。当然，工质在工质循环流动结构内流动的过程中形态会在气态与液态之间变化。
在本申请实施例中，隔离部300发挥隔离作用，隔离部300使得气态工质输入通道105和液态工质回流通道104形成一定的隔离，隔离部300隔离气态工质输出口102和液态工质回流口103，从而能够避免从气态工质输出口102输出的气态工质直接进入到液态工质回流口103，也能够避免即将进入到液态工质回流口103的液态工质直接进入气态工质输出口102，从而能够避免液态工质与气态工质之间的相互干扰。
在散热器工作的过程中，液态工质在基座100的蒸发腔101内发生蒸发而变成气态工质，气态工质通过气态工质输出口102进入到气态工质输入通道105的第一端部，紧接着在气态工质输入通道105内流动到气态工质输入通道105的第二端部，并通过气态工质输入通道105的第二端部进入到液态工质回流通道104中。由于冷凝部200的温度较低，温度较高的气态工质进入液态工质回流通道104后会与冷凝部200接触并进行冷凝，进而又变回液态工质。液态工质最终会通过液态工质回流通道104的第二端部和液态工质回流口103返回到蒸发腔101内，以进行下一循环。
当然，此过程中，待散热对象产生的热能够通过基座100加热工质以实现液态工质向气态工质的转变，此过程中，工质会吸热。待气态工质在液态工质回流通道104内冷却变成液态工质时会放热，冷凝放出的热会最终通过冷凝部200而散发到冷凝部200所处的环境中，达到散热的目的。此过程中，散热器将待散热对象产生的热经由工质的形态变化而转移到散热器所处的环境中，达到对待散热对象进行散热的目的。
通过上文所述的散热器工作过程可知，从蒸发腔101输出的气态工质会通过气态工质输入通道105向着液态工质回流通道104流动，而在液态工质回流通道104内形成的液态工质会通过液态工质回流口103流回到蒸发腔101。此过程中，温度较高的气态工质与温度较低的液态工质分别行走在由隔离部300隔离成的气态工质输入通道105和液态工质回流通道104中，而不 会发生接触，进而能避免相关技术中存在的气态工质与液态工质在流动过程中发生接触，进而能够避免气态工质与液态工质之间产生剪切力而带来的流动干扰，这无疑确保气态工质和液态工质不受干扰地流动，进而能够提高散热效果。可见，本申请实施例公开的散热器能够解决相关技术中散热器存在的散热效果较差的问题。
需要说明的是，在本文中，气态工质输入通道105的第一端部，指的是在气态工质输入通道105的邻近蒸发腔101的端部。气态工质输入通道105的第二端部，指的是气态工质输入通道105的远离蒸发腔101的端部。液态工质回流通道104的第一端部，指的是液态工质回流通道104的远离蒸发腔101的端部。液态工质回流通道104的第二端部，指的是液态工质回流通道104的邻近蒸发腔101的端部。
如上文所述，气态工质会通过气态工质输出口102从蒸发腔101内输出。而液态工质会通过液态工质回流口103而回流到蒸发腔101内，也就是说，在蒸发腔101内会同时存在气态工质和液态工质。为了避免相互之间产生过多的干扰，一种可选的方案中，蒸发腔101可以具有液态工质汇集区和蒸发区，液态工质汇集区和蒸发区为蒸发腔101的两个局部空间。蒸发区和气态工质输出口102连通，液态工质回流口103与液态工质汇集区连通。蒸发区内设有毛细结构400，毛细结构400能够将液态工质在蒸发区蒸发形成气态工质，进而从气态工质输出口102输送走。当然，液态工质汇集区和蒸发区连通，进而能够使得回流到蒸发腔101内的液态工质进入到蒸发区。此种分区布置的方式，能够在一定程度上减少气态工质和液态工质的接触，进而避免相互干扰。
在进一步的技术方案中，基座100包括围挡110，围挡110设于蒸发腔101内，且围绕毛细结构400设置。围挡110围成的空间为蒸发区，气态工质输出口102位于围挡110的内侧，液态工质回流口103和液态工质汇集区均位于围挡110的外侧。此种情况下，围挡110能够较好地确定蒸发区的边界，方便毛细结构400的准确安装。更重要的是，围挡110能够约束蒸发区形成的气态工质不会过于分散，更有利于气态工质较为集中地流向气态工质输出口102，这能够进一步提升散热器的散热效率。当然，围挡110能够隔离气态工质输出口102和液态工质回流口103，从而能够避免液态工质直接回流到蒸发区，而对蒸发产生不良影响。当然，需要说明的是，围挡110不 会完全隔离蒸发区和液态工质汇集区。
毛细结构400可以是金属粉末烧结结构件、金属纤维烧结结构件、金属泡沫、铲齿结构、微槽道结构等，本申请实施例对此不做限制。
在本申请实施例中，基座100由于设有蒸发腔101，因此可以认为基座100为中空结构。实现中空结构的方式有多种，例如，可以通过一整块板材通过折弯及密封工艺，来实现基座100的成型。
在一种可行的实施例中，基座100可以包括基板120和第一盖板130，基板120可以开设有凹槽121，第一盖板130与基板120相连，第一盖板130覆盖凹槽121的槽口。第一盖板130与基板120围成蒸发腔101，具体的，基板120上形成凹槽121的表面与第一盖板130围成蒸发腔101，在具体的制造过程中，可以在基板120上通过刻蚀、机加工等方式形成凹槽121，然后再将第一盖板130覆盖凹槽121的槽口，当然，第一盖板130与基板120之间可以设置密封胶，进而来实现两者之间的密封连接，确保蒸发腔101的密封性。此种方式具有方便制造的优势。
围挡110可以与第一盖板130相连，在此种情况下，可以先将围挡110与第一盖板130相连，然后将两者形成的整体安装在基板120上，有利于简化装配。在较为优选的方案中，围挡110与第一盖板130可以为一体式结构，在此种情况下，围挡110还能够发挥加强第一盖板130的强度的作用。
当然，围挡110也可以与第一盖板130焊接相连，第一盖板130可以与基板120焊接相连。为了提高散热能力，基座100、隔离部300和冷凝部200均可以采用铜材、铝材或其他散热性能较好的材料。
气态工质输出口102和液态工质回流口103可以开设在基板120上，也可以开设在第一盖板130上，本申请实施例不进行限制。在气态工质输出口102和液态工质回流口103开设在第一盖板130上，并且围挡110与第一盖板130连接的情况下，此种结构能够使得需要加工或装配的结构较为集中地设于第一盖板130，这无疑方便集中进行加工，进而提高加工效率。
在本申请实施例中，隔离部300和冷凝部200均可以安装于基座100上。具体的，隔离部300和冷凝部200可以固定在基座100上。由于基座100为空心结构，可能会存在支撑强度不足的问题。基于此，在较为优选的方案中，基座100还可以包括呈阵列分布的多个支撑凸起140，所述的多个支撑凸起140支撑于凹槽121的底壁与第一盖板130之间。需要说明的是，凹槽121 的底壁与第一盖板130相对分布。毛细结构400设有避让孔410，与毛细结构400对应的支撑凸起140穿设在对应的避让孔410中，从而避免毛细结构400对支撑凸起140布设的影响。
同时，在此种情况下，所述的多个支撑凸起140支撑于第一盖板130和基板120之间，从而能够提高整个基座100的强度。当然，所述的多个支撑凸起140能够起到支撑第一盖板130的作用，从而在隔离部300和冷凝部200安装于第一盖板130的情况下，较好地缓解第一盖板130的变形，进而使得第一盖板130能够较好地支撑隔离部300和冷凝部200。
为了减少装配操作，在优选的方案中，支撑凸起140与基板120可以为一体式结构。当然，支撑凸起140与基板120为一体式结构，也能够变相地认为支撑凸起140为基板120的加强凸起，进而能够提高基板120的抗变形能力。当然，支撑凸起140与基板120也可以为分体式结构，通过粘接、焊接等固定方式实现固定连接。
在本申请实施例中，冷凝部200和隔离部300均可以为一个。当然，冷凝部200和隔离部300均可以为多个，且均间隔分布。多个冷凝部200和多个隔离部300一一对应，以形成多个气态工质输入通道105和多个液态工质回流通道104。此种方式能够提高散热器的散热能力。
可选地，多个冷凝部200间隔地设于基座100上，每个液态工质回流通道104与相应的液态工质回流口103连通，每个气态工质输入通道105与相应的气态工质输出口102连通。此种结构能够使得散热器在多个位置均形成散热循环，进而能够提高散热器的散热能力。同时，间隔分布有利于相邻的冷凝部200之间的空气流通，进而提高冷凝散热能力。当然，在此种情况下，液态工质回流口103和气态工质输出口102均可以为多个，进而可以与多个冷凝部200和隔离部300建立对应的配合关系。
在本申请实施例中，冷凝部200和隔离部300均可以认为是空心构件，只要能够形成满足上文中气态工质和液态工质的循环流通的散热结构即可。请再次参考图1、图4、图5和图6，一种可选的方案中，冷凝部200可以包括冷凝扁管210和第二盖板220，隔离部300为板状结构，由于隔离部300具有气态工质输入通道105，因此在此种情况下，隔离部300实质为中空的板状结构。冷凝扁管210为扁形结构，冷凝扁管210的管腔也是扁形空间。隔离部300的板面可以与冷凝扁管210的扁平面相平行，从而能够使得隔离 部300的形状较好地适配冷凝扁管210。由于冷凝扁管210为扁平结构，进而较容易形成平整的换热面，进而有利于设计成较大的换热面积，从而来提高换热效率。当然，冷凝扁管210能够使得冷凝部200在一个方向设计成较小的尺寸，进而方便冷凝部200在该方向上尺寸确定的空间内进行更多的布设。
当然，在此种情况下，冷凝扁管210的第一条形端口与气态工质输出口102和液态工质回流口103的形状可以相适配(都是条形结构)、且连通，第二盖板220覆盖冷凝扁管210的第二条形端口，第二盖板220与隔离部300间隔设置，且形成衔接通道106，隔离部300与冷凝扁管210的内侧管壁之间形成液态工质回流通道104，衔接通道106连通液态工质回流通道104和气态工质输入通道105。此种通过第二盖板220覆盖冷凝扁管210的第二条形端口来形成衔接通道106的方式，结构较为简单，也较容易实现。
在其它实施例中，也可以在隔离部300上开设连通孔，通过连通孔来替代衔接通道106，进而来连通液态工质回流通道104和气态工质输入通道105。
在进一步的技术方案中，隔离部300的与冷凝扁管210的内壁之间形成围绕气态工质输入通道105的液态工质回流通道104，此种环绕结构有利于液态工质的回流。气态工质输出口102为冷凝扁管210的第一条形端口形状相适配的条形孔，此处形状相适配，指的是都是条形结构。气态工质输出口102在其长度方向的两侧均设有液态工质回流口103，液态工质回流通道104与位于气态工质输出口102的长度方向的两侧的两个液态工质回流口103均连通。在此种情况下，液态工质能够通过两个液态工质回流口103进行回流，无疑能够提高回流效率。与此同时，气态工质输出口102为条形孔，能够较适配板状结构的隔离部300。
在隔离部300为板状结构的情况下，气态工质输入通道105可以为扁平的长方体结构，气态工质输入通道105的宽度不小于0.5mm，当然，气态工质输入通道105的宽度指的是在垂直于板状结构的隔离部300的板面方向的尺寸。
如上文所述，冷凝部200为多个的情况下，每个冷凝部200的第二盖板220相连，且形成整体式结构。在此种情况下，将多个冷凝部200的第二盖板220形成整体式结构，从而能够使得在装配的过程中，操作人员可以先将多个冷凝部200的冷凝扁管210安装到基座100上，然后再用一整块板子覆 盖在所有的冷凝扁管210的端口上，从而与每个冷凝扁管210内的隔离部300围成衔接通道106。此种方式无疑有利于装配。当然，多个第二盖板220为一体式结构，实质是将多个冷凝部200连接起来，这能够提高整个散热器的整体强度。
为了进一步提高冷凝效果，在本申请实施例中，冷凝部200的外侧表面可以设有多个散热翅片500，所述的多个散热翅片500可以间隔分布。散热翅片500的设置能够提高冷凝部200与环境的换热能力，进而有利于提高冷凝能力。
在较为优选的方案中，冷凝部200为多个，每个冷凝部200内设置有隔离部300，多个冷凝部200间隔地设于基座100上，相邻的两个冷凝部200通过位于两者之间的散热翅片500相连。在此种情况下，冷凝部200不但可以以基座100为安装基础，同时冷凝部200之间可以通过散热翅片500连接，从而形成更稳固的连接结构，这能够提高整个散热器的强度。
本申请实施例中涉及的工质可以是水，也可以是油液，本申请实施例不限制工质的具体种类。
在本申请实施例中，隔离部300与冷凝部200之间的间隙宽度可以大于0.5mm。为了充分发挥分腔效果，隔离部300的高度优选大于冷凝扁管210的高度的1/2。同时为了避免衔接通道106的流阻过大，隔离部300的高度至少比冷凝扁管210的高度小5mm。当然，此处的高度，指的是基于基座100上的同一基准面(例如基座100上用于支撑冷凝部200和隔离部300的平面)上考虑的。
基于本申请实施例公开的散热器，本申请实施例进一步公开一种电子设备，所公开的电子设备包括热源器件和散热器，基座100设置在热源器件上，散热器为上文实施例中任一项所述的散热器。
当然，需要说明的是，此处的热源器件就是上文所述的待散热对象。本申请实施例涉及的热源器件可以是交换机中的处理器，也可以为电子设备中其它在工作时能够产热的器件，本申请实施例对此不做限制。
本申请上文实施例中重点描述的是各个实施例的不同，各个实施例的不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域 技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
