参见图1-10，本申请第一实施例提供了一种热管理系统10，该热管理系统10包括第一换热管路110、第二换热管路120、连接第一换热管路110和第二换热管路120的阀门200、与第一换热管路110进行热交换的功能部件300以及配置在第二换热管路120上的加热模块400。
如图1-3所示，第一换热管路110、第二换热管路120用于容纳换热介质700，换热介质700能够在第一换热管路110、第二换热管路120限定出的环形通路内循环流动，实现热量的转移。换热介质700可以为气态、液态或气液混合状态。本实施例中，换热介质700为液态，具体可以为液态水。加热模块400用于加热第二换热管路120中流动的换热介质700，换热介质700被加热后，通过在环形通路内流动，将热量传递至热管理系统10的其他部件，如功能部件300等。功能部件300配置为能够与第一换热管路110中的换热介质700进行热交换，如，能够吸收第一换热管路110中流动的换热介质700的热量，实现功能部件300的升温；或者，能够将自身热量传递至第一换热管路110中流动的换热介质700，实现功能部件300的降温。
加热模块400包括加热元件410，在一些实施例中，加热元件410优选地为正温度系数陶瓷加热元件（PTC），通过将电能直接转换为热能对第二换热管路120中流动的换热介质700加热。在其他实施方式中，加热元件410可以是一空调系统的冷凝器。冷媒在空调系统的蒸发器中吸收外部环境中的热量、在冷凝器中将所吸收的热量释放而对第二换热管路120中流动的换热介质700加热。
在一些实施例中，加热模块400还包括一换热器420，从而提高换热介质700的换热效率。
功能部件300为需要对其温度进行控制的元件，当热管理系统10应用于不同场景时，功能部件300即为对应该场景的需要进行温度控制的元件。如热管理系统10应用于电动汽车时，功能部件300可以是汽车的动力电池等。当外界气温过低时，热管理系统10需要对动力电池加热，使得动力电池升温，从而减少动力电池的低温衰减；当外界气温过高较高时，热管理系统10需要对动力电池降温，避免温度过高而影响使用安全。本实施例中，功能部件300可以直接贴合在第一换热管路110的管壁上，两者热接触进行热传导。
在一些实施例中，功能部件300与第一换热管路110也可以分开设置，两者之间可以连接有散热器、热管等导热部件，方便元件的布置和热量的传递；或者，两者之间可以通过热辐射的方式进行热量的传递，不以具体实施例为限。
阀门200设有互不连通的第一流道221和第二流道222，在不同的工作状态下，阀门200通过其第一流道221、第二流道222与第一换热管路110、第二换热管路120的连通或者不连通，使得第一换热管路110、第二换热管路120限定出一个或多个环形通路。当环形通路为多个时，各个环形通路可以相互连通，此时换热介质700可以由其中一个环形通路流动至另一个环形通路；或者，各环形通路可以互不相通，此时换热介质700仅能够在对应的环形通路内流动而不能由其中一个环形通路流动至另一个环形通路。本实施例中，阀门200具有至少三种不同的工作状态，具体地：
阀门200在第一工作状态下，参见图1，第一流道221、第二流道222串接于第一换热管路110和第二换热管路120之间，使得第一换热管路110和第二换热管路120相互连通并串联形成第一环形通路L1。换句话说，阀门200处于第一工作状态时，第一换热管路110和第二换热管路120共同限定出的第一环形通路L1，换热介质700能够由第二换热管路120流向第一换热管路110，热量可以由第二换热管路120向第一换热管路110转移，对功能部件300加热。
阀门200在第二工作状态下，参见图2，第一流道221连通第一换热管路110的两端形成第二环形通路L2，第二流道222连通第二换热管路120的两端形成第三环形通路L3，第二环形通路L2与第三环形通路L3相互并联并且不相连通。换句话说，阀门200处于第二工作状态时，部分换热介质700能够在第一换热管路110中循环流动，部分换热介质700能够在第二换热管路120中循环流动，但是换热介质700不能由第二换热管路120流向第一换热管路110，热量不能由第二换热管路120向第一换热管路110转移，功能部件300通过在第一换热管路110中循环流动的换热介质700散热。
阀门200在第三工作状态下，参见图3，第一流道221、第二流道222串连第一换热管路110和第二换热管路120并共同形成第一环形通路L1的同时，第一流道221连通第一换热管路110的两端而形成第二环形通路L2，和/或，第二流道222连通第二换热管路120的两端而形成第三环形通路L3，而且第一环形通路L1相对于第二环形通路L2或第三环形通路L3的换热介质700流量比可通过操作阀门200而变化。
阀门200处于第三工作状态时，部分换热介质700能够在第一换热管路110和第二换热管路120中循环流动，部分换热介质700能够在第一换热管路110或第二换热管路120中循环流动，热量可以由第二换热管路120向第一换热管路110转移且所转移的热量多少可以通过在第一换热管路110和第二换热管路120中循环流动的换热介质700的流量来控制，即可以通过操作阀门200来控制。
当功能部件300需要升温（如电池温度过低）时，将阀门200调整至第一工作状态或第三工作状态。此时，第一换热管路110与第二换热管路120串联并相互连通，第二换热管路120中的换热介质700被加热模块400加热后全部（第一工作状态）或者部分（第三工作状态）流动至第一换热管路110中，将加热模块400所产生的热量传递至功能部件300以实现升温，使得用于加热的能量被充分利用，提高了能源利用率。
当功能部件300需要降温（如电池温度过高）时，将阀门200调整至第二工作状态。此时，第一换热管路110与第二换热管路120并联并且互不相通，第一换热管路110单独限定出第二环形通路L2，第二换热管路120单独限定出第三环形通路L3，第二换热管路120中的换热介质700无法流通至第一换热管路110，杜绝加热模块400的热量向第一换热管路110以及功能部件300的传递，功能部件300自身所产生的热量通过第一换热管路110中流动的换热介质700散发，实现功能部件300的降温。由于第一换热管路110与第二换热管路120之间没有换热介质700流动，可以在第二换热管路120内的换热介质被加热的同时不影响功能部件300的正常散热，避免了功能部件300散热不良的问题。
本申请实施例提供的热管理系统10，能够良好的匹配功能部件300的各种换热需求，热损失少，换热效果佳。
换热介质700可以通过自发地在第一换热管路110和/或第二换热管路120中流动，也可以通过驱动件，如泵等的驱动在第一换热管路110和/或第二换热管路120中流动。本实施例中，参见图1-2，热管理系统10还包括第一驱动件510，第一驱动件510串接于第一换热管路110中。当阀门200处于第一工作状态时，第一驱动件510驱动换热介质700在第一环形通路L1，包括第一换热管路110和第二换热管路120中流动。当阀门200处于第二工作状态时，第一驱动件510驱动换热介质700在第二环形通路L2，即第一换热管路110中流动。
在一些实施例中，热管理系统10还包括第二驱动件520，第二驱动件520串接于第二换热管路120中。当阀门200处于第一工作状态时，第一驱动件510和第二驱动件520对于换热介质700的驱动方向相同，两者共同驱动换热介质700在第一环形通路L1内流动。当阀门200处于第二工作状态时，第二驱动件520驱动换热介质700在第三环形通路L3，即第二换热管路120中流动。本实施例中，第二驱动件520的驱动压力与第一驱动件510的驱动压力相同。在一些实施例中，第二驱动件520的驱动压力可以大于或小于第一驱动件510的驱动压力。
为了使第一换热管路110内的换热介质700能够始终沿单一方向流动，本实施例中，热管理系统10还包括串接于第一换热管路110中的单向阀600。
参见图1-3，第一换热管路110包括相对的第一端口111和第二端口112，第二换热管路120包括相对的第三端口121和第四端口122。参见图4-6，阀门200设有第一接口211、第二接口212、第三接口213以及第四接口214。其中，阀门200的第一接口211、第二接口212分别与第一换热管路110的第一端口111、第二端口112对接，阀门200的第三接口213、第四接口214分别与第二换热管路120的第三端口121、第四端口122对接。阀门200通过其第一流道221、第二流道222对于其第一接口211、第二接口212、第三接口213以及第四接口214之间的导通方式进行调整，实现第一工作状态、第二工作状态以及第三工作状态的切换。
具体地，如图4-7所示，阀门200包括阀座210和可转动地设置于阀座210中的阀芯220。阀座210呈圆筒状，包括基板215以及由基板215的外边缘垂直延伸的环形侧板216，基板215和侧板216合围形成收容阀芯220的空间。第一接口211、第二接口212、第三接口213以及第四接口214贯穿基板215，并且顺延基板215的圆周方向间隔设置。较佳的，第一接口211、第二接口212、第三接口213以及第四接口214均呈扇环形且大小相当，各接口211~214所对应的圆心角分别约为90°。
阀芯220为圆柱状，其面向阀座210的基板215的轴向端内凹形成所述第一流道221和第二流道222。第一流道221和第二流道222均为半圆形，所对应的圆心角分别约为180°。阀芯220配置为能够相对于阀座210的中心轴线在第一位置和第二位置之间转动，第一位置和第二位置优选地在周向上相差90度。阀芯220在不同位置时，第一流道221和第二流道222与第一接口211、第二接口212、第三接口213以及第四接口214的导通情况不一样，从而阀门200的工作状态不一样，具体地：
参见图1和图8，当阀芯220转动至第一位置时，阀门200处于第一工作状态。此时，第一流道221正对第一接口211和第四接口214并将两者导通，使得第一换热管路110的第一端口111和第二换热管路120的第四端口122连通；同时，第二流道222正对第二接口212和第三接口213并将两者导通，使得第一换热管路110的第二端口112和第二换热管路120的第三端口121连通。如图中箭头所示，换热介质700能够从第二换热管路120顺序通过第四接口214、第一接口211流入至第一换热管路110，同时能够从第一换热管路110顺序通过第二接口212、第三接口213流入至第二换热管路120，在第一环形通路L1中循环流动。
参见图2和图9，当阀芯220转动至第二位置时，阀门200处于第二工作状态。此时，第一流道221正对第一接口211和第二接口212并将两者导通，使得第一换热管路110的第一端口111和第二端口112连通；同时第二流道222正对第三接口213和第四接口214并将两者导通，使得第二换热管路120的第三端口121和第四端口122连通。如图中箭头所示，由第一换热管路110的第二端口112流出的换热介质700经过第二接口212、第一接口211回到第一换热管路110，在第二环形通路L2中循环流动；由第二换热管路120的第四端口122流出的换热介质700经过第四接口214、第三接口213回到第二换热管路120，在第三环形通路L3中循环流动。
参见图3和图10，阀门200在由第一位置转动至第二位置的过程中还能到达第三位置，使得阀门200处于第三工作状态。此时，第一流道221正对第一接口211以及部分第二接口212和部分第四接口214，使得第一换热管路110的第一端口111既能与其第二端口112连通，又能与第二换热管路120的第四端口122连通；同时，第二流道222正对第三接口213以及部分第二接口212和部分第四接口214，使得第二换热管路120的第三端口121既能与其第四端口122连通，又能与第一换热管路110的第二端口112连通。
如图中箭头所示，换热介质700由第二换热管路120的第四端口122进入第四接口214后，一部分经由第三接口213回到第二换热管路120，在第三环形通路L3中流动，一部分经由第一接口211进入第一换热管路110，在第一环形通路L1中流动；同时，换热介质700由第一换热管路110的第二端口112进入第二接口212后，一部分经由第一接口211回到第一换热管路110，在第二环形通路L2中流动，一部分经由第三接口213进入第二换热管路120，在第一环形通路L1中流动。也就是说，部分换热介质700能在第一环形通路L1中循环流动，部分换热介质700能在第二环形通路L2中循环流动，并且部分换热介质700能在第三环形通路L3中循环流动。
本实施例中，通过控制阀芯220相对于阀座210的转动角度来控制第一流道221与第二接口212、第四接口214的导通与否以及导通时导通面积的大小，以及控制第二流道222与第二接口212、第四接口214的导通与否以及导通时导通面积的大小，可以用来控制第三状态下所述第一环形通路L1相对于第三环形通路L3中换热介质的流量比。第一流道221与第四接口214导通时的导通面积越大，则第一流道221与第二接口212的导通面积越小；相应地，第二流道222与第二接口212的导通面积越大、则与第四接口214的导通面积越小。通过对阀芯220的转动角度的控制，使得第一流道221和第二接口212的导通面积与第一流道221和第四接口214的导通面积之比可变，第二流道222和第二接口212的导通面积与第二流道222和第四接口214的导通面积之比可变。
当第一流道221与第四接口214的导通面积较大、第二流道222与第二接口212的导通面积较大时，换热介质700在第二换热管路120中被加热模块400加热后，大部分会分流至第一换热管路110，功能部件300的升温速率更快、升温上限更高；当第一流道221与第四接口214的导通面积较小、第二流道222与第二接口212的导通面积较小时，被加热模块400加热后的换热介质700少部分会由第二换热管路120分流至第一换热管路110，功能部件300的升温速率更慢、升温上限更低，如此能够根据需要实现对功能部件300的精准控温。
可以理解的是，阀门200处于第三工作状态时，第一流道221与第四接口214的导通面积小于第四接口214本身的面积，第二换热管路120只有部分换热介质700分流至第一换热管路110，因此阀门200处于第三工作状态时对功能部件300的加热效果要弱于阀门200在第一工作状态时对功能部件300的加热效果。当功能部件300需要快速升温或者升温至较高度数时，可以选择将阀门200调整至第一工作状态；反之，可以选择将阀门200调整至第三工作状态。
在一些实施例中，阀芯220还包括驱动轴226，驱动轴226由阀芯220的中央向外（即背向阀座210的基板215）延伸，用于连接外部驱动件，如电机等。较佳的，驱动轴226连接齿轮，电机通过齿轮啮合传动，驱使阀芯220相对于阀座210转动。本实施例中，阀芯220中央朝向阀座210延伸有转轴227，阀座210的基板215的中央设有轴孔217，转轴227可转动地插接于轴孔217中，使得阀芯220相对于阀座210的转动更加平稳。第一流道221和第二流道222分布于转轴227的相对两侧，第一接口211、第二接口212、第三接口213以及第四接口214环绕轴孔217均匀间隔布置。
在一些实施例中，阀芯220的侧端与阀座210的基板215之间夹置有密封件230，如密封圈、密封垫等。参见图4-6，本实施例中，密封件230为密封垫，采用柔性材质，如橡胶、硅胶等制成，能够有效减小换热介质700由阀芯220与阀座210的结合处泄露的几率。密封件230形成有第一通孔231、第二通孔232、第三通孔233以及第四通孔234，分别正对阀座210的第一接口211、第二接口212、第三接口213以及第四接口214，避免影响阀座210的各个接口211~214与阀芯220相应的流道221、221的导通。密封件230的中央设有穿孔237供转轴227穿设，第一通孔231、第二通孔232、第三通孔233以及第四通孔234环绕穿孔237分布。
图11-12所示为本申请第二实施例提供的热管理系统10，其与第一实施例中的不同之处主要在于的阀门200的阀芯220。本实施例中，阀芯220面向阀座210的一侧设置有第一流道221和第二流道222，其中第一流道221为半圆形，其对应的圆心角大约为180°；第二流道222为扇形，所对应的圆心角小于180°。
阀芯220在由第一位置转动至第二位置的其中一段行程内，第二流道222在连通第三接口213和部分第二接口212的同时，与第四接口214完全错开，使得第三接口213和第四接口214不能连通。此时，由第二换热管路120的第四端口122流出的换热介质700，只能通过第四接口214、第一接口211流入第一换热管路110；由第一换热管路110的第二端口112流出的换热介质700，可以通过第二接口212、第一接口211回到第一换热管路110，也可以通过第二接口212、第三接口213流入第二换热管路120。也就是说，阀门200在第三工作状态下，换热介质700可以仅在第一环形通路L1和第二环形通路L2中流动，使得热管理系统10整体的热效率更高。
在一些实施例中，第一流道221也可以设置为扇形，所对应的圆心角小于180°。阀芯220在由第一位置转动至第二位置的其中一段行程内，第一流道221在连通第一接口211和部分第四接口214时，与第二接口212完全错开，使得第一接口211和第二接口212不能连通。此时，由第一换热管路110的第二端口112流出的换热介质700，只能通过第二接口212、第三接口213流入第二换热管路120；由第二换热管路120的第四端口122流出的换热介质700，既能通过第四接口214、第三接口213回到第二换热管路120，也能通过第四接口214、第一接口211流入第一换热管路110。也就是说，阀门200在第三工作状态下，换热介质700可以仅在第一环形通路L1和第三环形通路L3中循环流动，使得热管理系统10整体的热效率更高。
图13-20所示为本申请第三实施例提供的热管理系统10，其与第一实施例的不同之处主要在于阀门200。
参见图14至图17，阀门200包括阀座210和转动地设置于阀座210中的阀芯220。阀座210的基板215设置有贯穿的第一接口211、第二接口212、第三接口213、第四接口214以及第五接口218，其中第一接口211、第五接口218所对应的圆心角约为45°，第二接口212、第三接口213、第四接口214所对应的圆心角约为90°。
参见图13，本实施施例的热管理系统也具有第一换热管路110及第二换热管路120。所述第一换热管路包括相对的第一端口111和第二端口112，第二换热管路120包括相对的第三端口121和第四端口122。所述第三接口213和第五接口218同时对接所述第二换热管路120的第三端口121；第一接口211、第二接口212、第四接口214分别对接第一端口111、第二端口112、第四端口122。
在本实施方式中，热管理系统10还包括一汇流板800。汇流板800装在阀座210的基板215的外侧，形成有贯穿的第一连接孔811、第二连接孔812、第三连接孔813、第四连接孔814以及第五连接孔818，分别用于对接所述阀门200的第一至第五接口211、212、213、214、218与所述第一、第二换热管路110、120的第一端口111、第二端口112、第三端口121、第四端口122。汇流板800设有一通槽810，通槽810连通第三连接孔813和第五连接孔818，将阀座210的第三接口213和第五接口218导通并共同对接所述第二换热管路120的第三端口121。在一些实施例中，汇流板800与阀座210也可以集成为一体。
阀芯220设有面向阀座210的基板215的一侧开口的第一流道221和第二流道222，第一流道221和第二流道222大致为弧形，所对应的圆心角约为135度。第一流道221和第二流道222相应的端部之间形成分隔部223，分隔部223所对应的圆心角约为45度。分隔部223使得第一流道221和第二流道222互不相通。如图17所示，第一流道221和第二流道222的中部分别形成有挡板224，挡板224位于阀芯220面向阀座210的一侧，挡板224的厚度小于第一流道221/第二流道222的深度，使得第一流道221/第二流道222的周向两端在开口侧呈断开状、在各自内部为连通状。
参见图18，当阀门200处于第一工作状态时，所述第一流道221的挡板224完全遮盖第五接口218，所述第二流道222的挡板224和两个分隔部223分别对第二接口212、第三接口213和第四接口214形成半遮盖，第一接口211完全露出。第一流道221连通第一接口211和第四接口214；第二流道222连通第二接口212和第三接口213。如图中箭头所示，第一换热管路110中的换热介质700经由第二端口112进入第二接口212内后，经过第三接口213而进入第二换热管路120；第二换热管路120中的换热介质700经由第四端口122进入第四接口214后，经过第一接口211而进入第一换热管路110，形成沿类似第一实施例中的第一环形通路L1的流动循环。
参见图19，当阀门200转动至第二工作状态（如转动90°）时，一个分隔部223转动至完全遮挡第五接口218，第一接口211完全露出，第二接口212、第三接口213和第四接口214被另一分隔部223和两个挡板224半遮挡。第一流道221连通第一接口211和第二接口212；第二流道222连通第三接口213和第四接口214。如图中箭头所示，第一换热管路110中的换热介质700经由第二端口112进入第二接口212后，通过第一接口211回到第一换热管路110，形成沿类似第一实施例中的第二环形通路L2的循环流动；第二换热管路120中的换热介质700经由第四端口122进入第四接口214后，通过第三接口213回到第二换热管路120，形成沿类似第一实施例中的第三环形通路L3的循环流动。
参见图13和图20，当阀门200转动至第三工作状态（如转动30°）时，所述第一流道221的挡板224转动至同时部分遮盖第四接口214和第五接口218，所述第二流道222的挡板224转动至横跨第二接口212与第三接口213而分别部分遮挡第二接口212和第三接口213。第一流道221用于将第四接口214同时连通第一接口211与第五接口218；第二流道222用于将第二接口212连通第三接口213；由于通槽810连通第三接口213和第五接口218，如此第三接口213能够同时连通第二接口212和第五接口218，第二流道222能够与第五接口218连通。
如图13中箭头所示，第二换热管路120内的换热介质700通过其第二端口122进入阀门的第四接口214后，一部分经过第一接口211进而通过第一换热管路110的第一端口111进入所述第一换热管路110，另一部分还可经由第五接口218，进而通过第二换热管路120的第三端口121回到第二换热管路120；第一换热管路110中的换热介质700通过其第二端口112进入阀门的第二接口212后，经过第三接口213，进而通过第二换热管路120的第三端口121进入第二换热管路120，从而能够同时形成类似第一实施例中的第一环形通路L1及第三环形通路L3的循环流动。
本实施例可以通过控制阀芯220相对于阀座210的转动角度来控制第一流道221与第一接口211、第四接口214、第五接口218的导通与否以及导通时导通面积的大小来控制第三状态下所述第一环形通路L1相对于第三环形通路L3中换热介质的流量比。例如，顺时针转动时，第一流道221和第一接口211的导通面积变大，同时第一流道221和第五接口218的导通面积变小。反之，逆时针旋转时，第一流道221和第一接口211的导通面积变小，同时第一流道221和第五接口218的导通面积变大。
