如图2和图3所示，热管理组件包括第一安装块3，第一安装块3与芯体组件10固定连接，加热器20与第一安装块3固定连接。芯体组件10包括相互隔离的第一流体通道11和第二流体通道，第一流体通道11和第二流体通道内的流体能够热交换。第一安装块3具有第一通道31，加热器20具有加热通道57，通过形成加热通道57的壁可对流经的流体加热。第一通道31一端与第一流体通道11连通，第一通道31的另一端与加热通道57连通。加热器20通过第一安装块3与芯体组件10连接，可减少管路以及连接部件，从而减少泄漏风险、减少沿途压降，可提高系统的集成度以及减少能耗。
如图3和图5所示，热管理组件300包括第二安装块9和膨胀阀组件8，膨胀阀组件8与第二安装块9固定连接，第二安装块9与芯体组件10焊接固定。沿芯体组件10的板片堆叠方向，第二安装块9与第一安装块3位于芯体组件10的两端，使得加热器20与膨胀阀组件8不相互干涉。第二安装块9具有第二通道91，第二通道91与第二流体通道连通。膨胀阀组件8具有节流通道，节流通道与第二通道91连通，膨胀阀组件8可通过调节节流通道的大小来控制经过第二流体通道的流量以及节流效果。膨胀阀组件8通过第二安装块9与芯体组件10固定连接，进一步提高了热管理组件的集成度，可减少管路以及连接部件，从而减少泄漏风险，提高集成度以及减少能量损失。在其它实施方式中，膨胀阀组件8可与第二安装块9一体设置。热管理组件还包括第三接头17和第四接头16，第三接头17具有第三通道171，第三通道171与第二流体通道连通。
如图3和图5所示，芯体组件10包括多个金属材质的板片18，多个板片堆叠设置，并通过焊接成为整体，板片堆叠方向在图2、图5、图8 和图10中以方向Z示出。第一安装块3也为金属材质，沿板片堆叠方向，第一安装块3位于芯体组件10的一端并与芯体组件10焊接固定，加热器20与第一安装块3位于板片堆叠方向的同一端。第一流体通道11包括第一孔道13、板间通道15和第二孔道14，第一孔道13和第二孔道14位于芯体组件10第一方向的两端。第四接头16具有第四通道161，第四通道161与第一流体通道11连通。在本实施方式中，板片18具有底部以及环绕底部的侧壁部，板片18的底部为长方形或大致为长方形，板片18底部的长边的延伸方向即为芯体组件10的第一方向，芯体组件10的第一方向在图3、图5、图8中以方向Y示出，芯体组件10的第一方向与板片堆叠方向垂直或大致垂直。
如图3所示，第一安装块3与第一孔道13位于芯体组件10第一方向的同一端，第一安装块3的第一通道31与第一孔道13连通。加热器20包括壳体4和加热管组件5，壳体4具有容纳腔41，加热管组件5的至少一部分位于容纳腔41，加热管组件5具有加热通道57。加热管组件5包括发热膜，发热膜位于加热管组件5外周，可通过发热膜加热形成加热通道57的壁，从而加热流经加热通道57的流体，发热膜可由快速产热的纳米材料制成。在本实施方式中，加热通道57为直通道或大致为直通道，使得加热通道内的流阻较小，加热管组件5也为筒状，相应地，加热器20也为柱形或大致为柱形，加热器20的轴向为加热通道57的延伸方向。加热器20的轴向与芯体组件10的第一方向相同或大致相同，加热管组件5的一端与第一安装块3连接，加热器20由第一安装块3向第二孔道14的方向延伸。此结构使得，在芯体组件10的第一方向上，加热器20的一部分长度与芯体组件10的长度重合，从而可减少热管理组件300的总体长度，有利于热管理组件300的小型化，使得热管理组件300的结构更为紧凑。在加热器20的其它实施方式中，加热器20也可通过加热丝加热流体，如图10所示，加热器20与第一安装块3一体设置，加热器20包括设置于加热通道57内的加热丝59，通过加热丝59加热流经加热通道57的流体。沿板片堆叠方向，第一安装块3位于芯体1的一端并与安装板2螺钉固定。
如图3和图4所示，第一安装块3包括焊接部32和第一接口部33， 焊接部32与芯体组件10焊接固定，第一安装块3包括位于焊接部32的第一连接口38，第一通道31与第一连接口38连通，第一连接口38与第一流体通道11连通，且焊接部32与芯体组件10密封设置，形成第一通道31的壁与第一接口部33连接。在本实施方式中，第一安装块3为块状，第一安装块3具有多个侧面，第一接口部33与焊接部32位于第一安装块3不同的侧面。沿芯体组件10的第一方向，第一接口部33朝向第二孔道14。如图3和图5所示，加热管组件5还包括第一接头54和第二接头55，第一接头54和第二接头55位于加热管组件5的两端，加热通道57沿加热器20的轴向贯穿第一接头54、第二接头55。第一接头54的至少一部分沿加热器20的轴向突出于壳体4的一端面。连接加热器20与第一安装块3时，第一接头54的至少一部分插入第一接口部33，若干密封圈7设置于第一接头54与第一接口部33之间，第一接头54与第一接口部33之间密封设置。第一接头54的外周设置有环形凹槽541，密封圈7的至少一部分位于环形凹槽541。第一安装块3还具有沿加热器20的轴向延伸的第四安装孔35，第四安装孔35位于第一接口部33周围。壳体4的一端具有沿加热器20的轴向延伸的第五安装孔201(示于图5)，第一安装块3通过第四安装孔35(示于图6)与加热器20螺钉固定，螺钉插入第五安装孔201和第四安装孔35。在本实施方式中，板片为长方形，板片的短边的延伸方向为芯体组件10的第二方向，芯体组件10的第二方向与第一方向垂直或大致垂直，且芯体组件10的第二方向平行于板片延伸方向。第一接口部33位于或大致位于芯体组件10的第二方向的中间位置，因此，在芯体组件10的第二方向上，加热器20的一部分长度与芯体组件10的长度重合，从而可减小热管理组件300的总体长度，有利于热管理组件300的小型化。在第一安装块3的其它实施方式中，根据加热器20与芯体组件10之间相对位置的不同，与加热器20对应的第一接口部33可位于第一安装块3的其它侧面，本领域技术人员可根据需要来变化第一接口部33的位置，这里不再赘述。在板片的其它实施方式中，板片也可不为长方形，也可为正方形、圆形、平行四边形等。
如图3所示，第二流体通道内的流体为制冷剂，第一流体通道11内的 流体为冷却液。在车辆刚启动时，电池需要加热，加热器20开始工作，冷却液从加热器20的第二接头55进入加热通道57，经过加热的冷却液进入芯体组件10中的第一流体通道11，之后从第四通道161出来并去往电池温控器9对电池94进行加热。图3中的实心箭头示出了冷却液的流动路径。在车辆高速运行，电池需要冷却时，加热器20不工作，吸收了电池热量的高温冷却液从第二接头55进入芯体组件10，此时制冷剂系统工作，制冷剂从第二通道91进入芯体组件10的第二流体通道，吸收冷却液的热量后从第三通道171流出。
如图5和图6所示，芯体组件10包括安装板2和芯体1，芯体1由板片堆叠形成。安装板2包括主体部21，主体部21为板状且与板片平行或大致平行。沿板片堆叠方向，主体部21位于芯体组件10的一端且与芯体1固定连接，例如焊接固定。主体部21位于芯体1与加热器20之间，第一安装块3、加热器20与主体部21的一侧固定连接。安装板2具有沿第一方向突出于芯体1的第一安装部23，第一安装部23具有第一安装孔231，第一安装部23与加热器20螺钉固定。第一安装部23位于安装板2相对远离第一安装块3的一端，使得加热器20相隔较远的两端都得到固定，使得加热器20与芯体组件10之间的固定连接更为牢固，采用螺钉连接的方式也有利于拆卸与检修。在整车组装时，通过安装板2可将热管理组件300一次性固定至车体，节省了将芯体1、加热器20以及膨胀阀组件8分别与车体固定的步骤，提高了安装效率。
如图2和图6所示，安装板2包括第二安装部25，热管理组件300可通过第二安装部25与汽车的其它部位固定连接。在本实施方式中，安装板2包括两个第二安装部25，两个第二安装部25分别位于芯体组件10第二方向的两端，每个第二安装部25都具有两个以上的第三安装孔251，多个第二安装部25以及第三安装孔251可使得热管理组件300与汽车的安装更为牢固。安装板2还包括沿板片堆叠方向延伸的延伸部22，第二安装部25通过延伸部22与主体部21连接，两个延伸部22分别位于芯体组件10第二方向的两端，安装板2整体呈“几”字形结构并将加热器20包于其中。沿板片堆叠方向，延伸部22的长度大于或略大于加热器20的长度，可使 得加热器20悬空，使得加热器20不与汽车其它位置的安装面产生干涉。
在热管理组件300的其它实施方式中，第一安装块3的形状包括但不限于立方体的结构，第一安装块3也可为板状，或者包括管状部分。加热器20包括但不限于位于芯体组件10的底端，加热器20也可位于芯体组件10的侧方。如图7和图8所示，在热管理组件300的另一种实施方式中，第一安装块3为板状，第一安装块3可由两个以上板片叠加并焊接形成，第一安装块3的第一通道31可由镂空的板片形成。第一安装块3包括突出部37，第一安装块3的突出部37沿垂直于板片堆叠的方向突出于芯体组件10，第一接口部33位于突出部37。沿板片堆叠方向，第一安装块3与芯体组件10的一端连接，第一接口部33朝向芯体组件10的另一端，即第一接口部33与焊接部32位于第一安装块3的同一侧面。加热器20位于芯体组件第一方向的一侧，加热器20的轴向与板片堆叠方向相同。加热器20由第一安装块3向芯体组件10的顶端延伸，使得在板片堆叠方向上，加热器20的一部分长度与芯体组件10的长度重合，从而可减少热管理组件300的总体长度，有利于热管理组件300的小型化，使得热管理组件300更为紧凑。热管理组件300还包括安装部件27，沿板片堆叠方向，安装部件27和第一安装块3位于芯体组件10的两端，安装部件27一部分与芯体组件10的顶端焊接固定，安装部件27的另一部分具有第二安装孔，安装部件27与加热器20的外壳4螺钉固定。使得加热器20的两个相隔较远的部分得到固定，使得加热器20与芯体组件10之间的固定更为稳固，结构较为紧凑。需要说明的是，文中“顶端”和“底端”是在板片堆叠方向上芯体组件10的两端。
在热管理组件的又一种实施方式中，如图11和图12所示，加热器20可位于制冷剂系统100。加热器20与膨胀阀组件8串联设置。第一流体通道11内的流体为制冷剂，第二流体通道内的流体为冷却液。第一安装块3与芯体组件10固定连接，加热器20与第一安装块3固定连接，加热器20的加热通道57与第一流体通道11连通。膨胀阀组件8与第二安装块9固定连接，第二安装块9与芯体组件10固定连接，第二安装块9内的第二通道91与第一流体通道11连通。通过加热器20加热制冷剂，之后制冷剂进 入芯体组件10后加热冷却液，冷却液流出芯体组件10后加热电池94。
需要说明的是：以上实施例仅用于说明本专利而并非限制本专利所描述的技术方案，尽管本说明书参照上述的实施例对本专利已进行了详细的说明，但是，本领域的普通技术人员应当理解，所属技术领域的技术人员仍然可以对本专利进行修改或者等同替换，而一切不脱离本专利的精神和范围的技术方案及其改进，均应涵盖在本专利的权利要求范围内。
