请参阅图1至图5，热管理系统包括：冷却液循环流路和制冷剂循环流路。冷却液循环流路和制冷剂循环流路相互隔离而不流通。热管理系统还包括第一换热器7，第一换热器/第一双流道换热器7包括第一换热部71和第二换热部72，第一换热部71的流道和第二换热部72的流道相互隔离不连通。第一换热部71的流道连接于冷却液循环流路，第二换热部72的流道连接于制冷剂循环流路，即第一换热部71的流道为冷却液循环流路的一部分，第二换热部72的流道为制冷剂循环流路的一部分，流经第一换热部71的冷却液和流经第二换热部72的制冷剂能够在第一换热器/第一双流道换热器7内进行热交换。其中，冷却液可以是水和乙醇的混合液，制冷剂可以是C02等换热介质。热管理系统还包括第一换热组件8和第二换热组件9。第一换热组件8包括电池，第一换热组件8可以将电池产生的多余热量传递至冷却液，也可以将冷却液的热量传递给电池。第二换热组件9包括电机、逆变器等部件，第二换热组件9可以将电机等部件产生的多余热量传递给冷却液，也可以将冷却液的热量传递给电机等部件。第一换热组件8和第二换热组件9能够传递给冷却液的热量不同，因此，冷却液经过第一换热组件8和第二换热组件9时，各自的温度变化也不同。
如图1所示，粗实线部分为制冷剂的流动路线，细实线部分为冷却液的流动路线。制冷剂循环流路包括压缩机1、第一室内换热器2、第一调节装置3、室外换热器4和第三支路14。压缩机1的出口与第一室内换热器2的进口通过管路连接，第一室内换热器2的出口与第一调节装置3的第一端口通过管路连接，第一调节装置3的第二端口与室外换热器4的第一端口通过管路连接，室外换热器4的第二端口与第二换热部72的进口通过管路连接。第三支路14的一端与第一室内换热器2的出口通过管路连接，第三支路14的另一端与第二换 热部72的进口连接。连接室外换热器4与第二换热部72的管路可以与第三支路14设置连接支点作为汇流点，如此，制冷剂经第一室内换热器2后，可以分成两路，一路流向第三支路14，一路流向第一调节装置3。在其它实施例中，第二换热部72可以设置两个进口，一个进口连接第三支路14，室外换热器4通过管路直接连接第二换热部72的另外一个进口。
冷却液循环流路包括第一泵21、第一换热组件8、第二换热组件9和第一支路10。第一换热组件8和第一换热部71通过管路串联，第一换热组件8通过管路连接第一支路10、第二换热组件9。第一支路10的一端能够与第一换热组件8的出口连通，第一支路10的另一端与第二换热部72的入口能够连通，第二换热组件9的第一端口与第一换热组件8的出口能够连通，第二换热组件9的第二端口与第一换热部71的出口能够连通。第一泵21可以连接在第一换热组件8与第一换热部71之间的管路上，也可以连接在第一换热组件8和第二换热组件9之间的管路上。第一泵21用于驱动冷却液从第一换热组件8流向第二换热组件9。冷却液流路还可以连接一个压力水箱(图中未示出)，用于向冷却液循环流路注入更多的冷却液，提高流速或增加注入量。
本申请的热管理系统包括制热模式，可用于在冬季外界环境温度较低时，对车厢内环境进行制热，在制热模式下，压缩机1、第一室内换热器2、第一调节装置3、室外换热器4、第二换热部72连通形成回路，以及，压缩机1、第一室内换热器2、第三支路14、第二换热部72连通形成回路，制冷剂经第一室内换热器2后分成两个流路，一路流向第三支路14，一路流向第一调节装置3。制冷剂经室外换热器4后流向第二换热部72，制冷剂经第三支路14流向第二换热部72，流经室外换热器4后的制冷剂与第三支路14的制冷剂汇合后流向第二换热部72。在其它实施例中，流经室外换热器4后的制冷剂与第三支路14的制冷剂可以分别流向第二换热部72。在其他实施例中，流经室外换热器4后的制冷剂也可以不经过第二换热部72，而是直接回到压缩机1中。
在冷却液循环流路中，第一换热组件8、第二换热组件9和第一换热部71连通形成回路，以及，第一换热组件8、第一支路10和第一换热部71连通形成 回路，冷却液经第一换热组件8后，一路流向第一支路10，一路流向第二换热组件9，两路冷却液汇合后流向第一换热部71，冷却液循环流路的热量通过第一换热器7传递至制冷剂循环流路。其中冷却液经过电机时，温度会进一步变化。
在制热模式下，制冷剂流路的工作原理如下：制冷剂经压缩机1压缩成高温高压的气态，经第一室内换热器2时，第一室内换热器2作为冷凝器使用，制冷剂释放热量。热管理系统能够调节室内环境温度，热管理系统还包括风道16与风机23，风机23将空气送入风道16中，第一室内换热器2位于所述风道16内，风道16内的空气经过第一室内换热器2时，与制冷剂进行热交换，空气被加热后送入车厢内。降温后的制冷剂进入第一调节装置3节流后，制冷剂温度再次降低，制冷剂进入低温低压状态，低温低压的制冷剂进入室外换热器4中，通过室外换热器4与外界环境进行热交换，吸收外界环境的热量；进入第三支路14的低温低压制冷剂与经过室外换热器4后的低温低压的制冷剂汇合后流向第二换热部72，通过第二换热部72吸收流入第一换热部71内冷却液的热量后回到压缩机1再次被压缩。在其它实施例中，也可以只由第三支路14中的制冷剂经过第一换热器7的第二换热部72参与吸收冷却液流路的多余热量，最后经过第二换热部72后的制冷剂与未经过第二换热部72的两路制冷剂汇合后回到压缩机1，如此循环形成回路。
在本实施例中，制冷剂流路还包括气液分离器17，制冷剂经气液分离器17后回到压缩机1。在其它实施例中，气液分离器17可以设置两个管路连接入口，用于分别连接两路制冷剂，两路制冷剂同时流入气液分离器17内；也可以是气液分离器17只有一个连接入口，两路制冷剂先汇合后，再流入气液分离器17，制冷剂在气液分离17内气液分离后，气态制冷剂回到压缩机1，再次被压缩。在另一些实施例中，制冷剂流路也可以不包括气液分离器17，例如，制冷剂进入压缩机1前为气态而非气液两相状态，或压缩机1具有气液分离功能等情况。在另一些实施例中，两路制冷剂也可以不汇合，而是分别流向气液分离器17，同时进入气液分离器17内，若热管理系统不包括气液分离器17，两路制冷剂也 可以分别流向压缩机1，同时进入压缩机1内。
在本实施例中，制冷剂流路还包括流路调节装置18，流路调节装置18为四通阀，包括第一连接口181、第二连接口182、第三连接口183和第四连接口184。第一连接口181可以跟第二连接口182连通，也可以跟第四连接口184连通；第三连接口183可以跟第二连接口182连通，也可以跟第四连接口184。调节装置第一连接口181能够与室外换热器4连通，第二连接口182能够与第二换热部72的入口连通，所述第一调节装置3的第一端口与第三支路14均能够与第三连接口183连通，所述第四连接口184能够与第二换热器2的出口连通。流路调节装置18包括第一工作状态与第二工作状态，在第一工作状态下，第一连接口181与第二连接口182连通，第三连接口183与第四连接口184连通；在第二工作状态下，第一连接口181与第四连接口184连通，第二连接口182与第三连接口183不连通。在制热模式下，流路调节装置18处于第一工作状态，制冷剂从第一室内换热器2的出口流入流路调节装置18的第四连接口184，并从流路调节装置18的第三连接口183流出，制冷剂流出第三连接口183后分成两路，一路流向第一调节装置3的第一端口，一路流向第三支路14；以及，制冷剂经室外换热器4后，通过流路调节装置18，流向第二换热部72。
在本实施例中，制冷剂流路还包括调节装置第二调节装置19，第三调节装置19连接于第三支路14上，第三调节装置19可以具有导通状态、节流状态、阻断状态，使其可以具有导通、阻断第三支路14和对第三支路14上的制冷剂流体节流的功能。在制热模式下，当冷却液的温度较高，例如冷却液的温度高于20℃(该温度值可以是15℃-25℃之间，也可以根据冷却液实际所需的工作温度进行设定)，第三调节装置19处于节流状态，制冷剂经第三调节装置19节流降温，使制冷剂的温度在进入第二换热部72之前降低，可以吸收更多冷却液的热量。当冷却液的温度低于20℃时，温度相对低，需要维持电池的工作温度，因此，第三调节装置19处于导通状态，制冷剂经第三调节装置19时，状态不发生变化。在其它实施例中，第三调节装置19还可以阻断第三支路14，使制冷剂不经过第三支路14流入第二换热部72。
在制热模式下，冷却液流路的工作原理如下：第一泵21启动，经过第一换热组件8的冷却液分成两路，一路流向第二换热组件9，一路流向第一支路10，第一换热组件8包括电池，第二换热组件9包括电机时，电机的工作温度较高，电池所需的工作温度较低，因此，冷却液经第二换热组件9后会被加热。此部分高温的冷却液与经过第一支路10相对低温的冷却液混合后，形成温度适宜的冷却液，此状态的冷却液经过第一换热部71时，与经过第二换热部72的制冷剂进行热交换，冷却液将热量传递给制冷剂，冷却液降温，降温后的冷却液进入第一换热组件8时，刚好达到电池所需的工作温度。
需要说明的是，第一支路10的作用为分流出一部分冷却液，使部分冷却液不经过电机而被加热成高温的冷却液，形成相对低温和相对高温的两路冷却液，降低流向第一换热部71的冷却液温度，减小冷却液与制冷剂热交换后温度仍然高于电池所需的工作温度的可能，控制进入第一换热组件8的冷却液温度在一个适宜的范围，如此形成冷却液循环流路自身的温度调节机制。在制热模式下，制冷剂通过吸收冷却液的热量，对第一换热组件8和第二换热组件9产生的多余热量进行回收利用，以提升制热能力的同时，还可以调节电池工作温度。在其它实施例中，不需要提升热管理系统制热能力时，冷却液流路也可以不工作。
在制热模式下，第一换热组件8、第二换热组件9和第一换热部71连通形成回路，第一换热组件8、第一支路10和第一换热部71连通形成回路，冷却液经第一换热组件8后，一路流向第一支路10，一路流向第二换热组件9，两路冷却液汇合后流向第一换热部71，可以减少热管理系统用于余热回收的换热器数量。
在本实施例中，冷却液循环流路还包括第一流量调节装置11。第一流量调节装置11包括第一接口111、第二接口112和第三接口113，第一接口111能够与第一换热组件8通过管路连接，第二接口112与第一支路10通过管路连接，第三接口113与第二换热组件9连接。在制热模式下，第二接口112、第三接口113均与第一接口111导通，冷却液流经第一换热组件8后通过第一流量调节装置11进行分流。第一流量调节装置11为三通比例调节阀，可以调节进入第一 支路10的和流向第二换热组件9的冷却液流量。当较多的冷却液进入第一支路10时，意味着经过第二换热组件2后的高温冷却液在与经过第一支路10的相对低温的冷却液混合后，温度降低的更多。因此，第一流量调节装置11也可以起到调节进入第一换热组件8的冷却液的温度，以满足电池所需的工作温度。
在本实施例中，冷却液循环流路还包括第二支路12，在制热模式下，第二支路12和第二换热组件9连通形成回路，冷却液经第二换热组件9后，一路流向第二支路12，一路流向第一换热部71。在第二支路12上，设置第一控制阀22，方便控制第二支路12的通断。可以理解的是，第二支路12可以分流经过第二换热组件9的冷却液，因此，较少的高温冷却液与第一支路10中温度相对较低的冷却液混合，可以使冷却液在进入第一换热组件8之前的温度不会过高，同时，部分高温的冷却液流回第二换热组件9，仅仅回收部分热量，保证了电机所需的工作温度。第二支路12可根据实际情况通过第一控制阀22进行通断，用于调节冷却液循环流路的温度。
在本实施例中，冷却液循环流路还包括第二流量调节装置13，第二流量调节装置13包括第四接口131、第五接口132和第六接口133，第四接口131与第二换热组件9通过管路连接，第五接口132与第一换热部71通过管路连接，其中第一支路10的一端可以与第五接口132和第一换热部71通过管路连接，第六接口133与第二支路12通过管路连接。在制热模式下，第五接口132、第六接口133均与第四接口131连通，冷却液经第二换热组件9后通过第二流量调节装置13进行分流。第二流量调节装置13为比例调节阀，用于调节流向第二支路12和流向第一换热部71的冷却液流量，使热管理系统能更好地调节电机和电池的工作温度。需要说明的是，上述第一支路10和第二支路12的调节功能受到冷却液注入量的影响。因此，可在冷却液循环流路上连接压力水箱，用于调节冷却液的注入量，通过第一流量调节装置11和第二流量调节装置13进行流量的分配。本实施例的冷却液循环流路还包括第三控制阀26，第三控制阀26连接于第二换热组件9和第二流量调节装置13之间的管路上，控制管路的连通更加方便。在另外一些实施例中，第三控制阀26也可以连接于第二换热 组件9和第一流量调节装置11之间的管路上。
如图2、图3所示，制冷剂循环流路还包括第二室内换热器5和第二调节装置6，第二调节装置6的出口能够与第二室内换热器5的进口连通，用于对进入第二室内换热器5之前的制冷剂进行节流。冷却液循环流路还包括第二换热器15、第二控制阀25、第三控制阀26和第二泵20，第二换热器15可以是散热水箱，也可以是空气换热器，第二泵20设置在第二换热组件9的和第二换热器15之间的管路上，第二控制阀25连接在第二换热器15出口处，第三控制阀26连接于第二换热组件9出口处，在制热模式下，第三控制阀26开启，第二控制阀25关闭，第二泵20可以开启也可以关闭。热管理系统还包括制冷模式，在本实施例中，制冷模式包括第一工作模式和第二工作模式。
第一工作模式用于在夏季外界环境温度较高时，可以对车厢内环境进行制冷，同时还可以对电机和电池进行散热。如图2所示，粗实线部分为制冷剂的流动路线，细实线部分为冷却液流动的路线。在第一工作模式下：压缩机1、第一室内换热器2、流路调节装置18、室外换热器4、第一调节装置3、第二调节装置6、第二室内换热器5、气液分离器17连通形成回路；以及，压缩机1、第一室内换热器2、流路调节装置18、室外换热器4、第一调节装置3、第三支路14、第二换热部72连通形成回路。制冷剂经第一调节装置3后分流，一路流向第三支路14，一路流向第二室内换热器5，在其它实施例中，制冷剂也可以不经过第一调节装置3，制冷剂经室外换热器4后直接分流。而在本实施例中，第一调节装置3此时为导通状态，其具有多个功能用于在不同的模式切换。可以理解的是，第一调节装置3可以是一个阀件，同时具有导通功能和节流功能，也可以是至少两个阀件的组合阀。在本实施例中，第一调节装置3为组合阀，包括节流单元阀31和导通单元阀32，导通单元阀32可以是单向阀，也可以是双向的控制阀。在制冷模式下，节流单元阀31关闭，导通单元阀32开启，实现制冷剂的单向流通，即制冷剂由室外换热器4流向导通单元阀32，经导通单元阀32后流向第二换热部72。在制冷模式下，流路调节装置18处于第二工作状态。
在第一工作模式下，制冷剂循环流路的工作原理：制冷剂经压缩机1压缩成高温高压的气态，高温高压气态制冷剂经第一室内换热器2不进行换热，例如，可以通过风门阻挡空气经过第一室内换热器2。高温高压的气态制冷剂经室外换热器4与外界环境进行热交换，室外换热器4作为冷凝器使用，制冷剂释放热量后温度降低，并通过第一调节装置3的导通单元阀32后分成两个流路，制冷剂在导通单元阀32内的状态不发生变化。低温的制冷剂进入第二换热部72之前，可以选择第三调节装置19对制冷剂流路进行节流降温，也可以不进行节流，开启第三调节装置19的目的是为了降低制冷剂温度，使其在第二换热部72内吸收更多流经第一换热部71的冷却液的热量，达到为电机或电池进行散热的目的。当电机或电池不需要散热时，第三调节装置19可以关闭，阻断第三支路14；或只需带走一部分电机或电池的热量时，第三调节装置19为导通模式，不进行节流，制冷剂通过第三支路14流向第二换热部72。制冷剂在第二换热部72中，与第一换热部71内的冷却液进行热交换，吸收冷却液流路的热量，从而使电池在夏季高温环境下，工作温度不会太高或超出要求。另一路制冷剂经第二调节装置6节流降温后，进入第二室内换热器5，第二室内换热器5作为蒸发器使用，制冷剂通过第一室内蒸发器5与风道16内的空气进行热交换，空气的热量传递给制冷剂，空气降温后进入车厢内，使车厢内的环境温度降低。最后两路制冷剂经气液分离器17气液分离后回到压缩机1内再次被压缩，如此循环。
在第一工作模式下：冷却液循环流路的第一泵21开启，第一换热组件8、第一泵21、第一流量调节装置11、第一支路10、第一换热部71连通形成回路，第一换热组件8将电池的热量传递至冷却液，冷却液在第一泵21的驱动下在流路中流动，经过第一换热部71时，将热量传递至第二换热部72内的制冷剂，最后冷却液回到第一换热组件8中，再次吸收电池的热量，如此循环，以达到为电池散热的目的。第二泵20同时开启，第一控制阀22关闭，也可以是第二流量调节装置13的第五接口132、第六接口133与第四接口131均断开，也可以是第一流量调节装置11的第一接口111与第二接口112均与第三接口113不连通，使冷却液不经过第二支路12，而第二控制阀25与第三控制阀26均打开， 第二换热组件9、第二换热器15、第二泵20连通形成回路，第二泵20驱动冷却液流动，将电机的热量带至第二换热器15，通过第二换热器15与外界环境进行热交换，从而起到给电机散热的作用。
在其它实施例中，在第二工作模式下，第一换热组件8、第一泵21、第一流量调节装置11、第二换热组件9、第二流量调节装置13和第一换热部71连通形成回路，第二控制阀25关闭，第三控制阀26打开，冷却液不经过第二换热器15，第一流量调节装置11的第二接口112、第三接口113均与第一接口111连通，冷却液经第一换热组件8后，一路流向第一支路10，一路流向第二换热组件9，两路冷却液汇合后流向第一换热部71，冷却液循环流路的热量通过第一换热器/第一双流道换热器7传递给制冷剂循环流路。第二泵20可以开启也可以选择不开启，不开启的情况下，第二泵20仅作为管路使用。第一控制阀22可以关闭，也可以打开，第一控制阀22打开时，当冷却液流向第二支路12时，给电机和电池同时散热的时候，可以起到维持电机正常工作温度的作用。其原理与制热模式下，冷却液循环流路的工作原理相同，即，通过第一流量调节装置11和第三流量调节装置13来分配冷却液，调节冷却液传递给制冷剂的热量大小。
冬季外界环境温度较低时，制热模式下室外换热器4长期使用后其表面容易结霜，影响其换热性能。热管理系统在第二工作模式下，可利用电机和电池产生的多余热量可以对室外换热器4进行主动除霜。如图3所示，粗实线部分为制冷剂的流动路线，细实线部分为冷却液的流动路线。在第二工作模式下：制冷剂侧的工作原理与第一工作模式下制冷剂的工作原理相同，将室外蒸发器4作为冷凝器使用，制冷剂经室外换热器4的时候，释放热量，室外换热器4表面的结霜融化。在冷却液循环流路中，第一换热组件8、第一泵21、第一流量调节装置11、第二换热组件9、第二流量调节装置13和第一换热部71连通形成回路，第二控制阀25关闭，冷却液不经过第二换热器15，第一流量调节装置11的第二接口112、第三接口113均与第一接口111连通，冷却液经第一换热组件8后，一路流向第一支路10，一路流向第二换热组件9，两路冷却液汇合后 流向第一换热部71，冷却液循环流路的热量通过第一换热器7传递给制冷剂循环流路。第二泵20可以开启也可以选择不开启，不开启的情况下，第二泵20仅作为管路使用。第一控制阀22可以关闭，也可以打开，第一控制阀22打开时，当冷却液流向第二支路12时，给电机和电池同时散热的时候，可以起到维持电机正常工作温度的作用，冷却液循环流路的原理与制热模式下的冷却液循环流路的工作原理相同，即，通过第一流量调节装置11和第三流量调节装置13来分配冷却液，调节冷却液传递给制冷剂的热量大小。需要说明的是，在除霜过程中，第二室内换热器5作为蒸发器使用，会降低进入车厢的内的空气温度，因此可以选择通过设置风门，使空气绕过或不经过第二室内换热器5，第二室内换热器5内的制冷剂不进行换热。
在其它实施例中，在第二工作模式下，也可以控制第二调节装置6关闭，制冷剂从室外换热器4流向第三支路14，第二室内换热器5不工作，因此，车厢内不会吹冷风。
第一换热组件8包括电池，在电池充电或快速充电过程中，电池容易产生较多的热量，电池不能散热，会有安全隐患。热管理系统还包括电池散热模式，如图4所示，在电池散热模式下：制冷剂流路不工作，第一泵21启动，驱动冷却液在管路中流动，第二泵20不工作，第二控制阀25开启，第一控制阀22、第三控制阀26均关闭，第一控制阀22、第三控制阀26所在的支路不导通，第一流量调节装置11的第一接口111和第三接口113连通，第二接口112关闭，第一换热组件8、第一泵21、第一流量调节装置11、第二换热器15、第二控制阀25、第一换热部71连通形成回路，第一换热组件8将电池产生的热量通过第二换热器15传递至外界，使电池在充电过程中进行散热。
如图5所示，冷却液循环流路还包括加热器24，第一换热组件8还包括电池，热管理系统还包括电池加热模式。在电池加热模式下，压缩机1不工作，制冷剂循环流路不连通，第一控制阀22关闭，第二控制阀25关闭，第三控制阀26关闭，相应地，三个阀各自所在的支路不连通。第二泵20不工作，第一泵21开启，驱动冷却液流动，第一流量调节装置11的第一接口111和第二接口 112连通，第三接口113关闭，第一换热部71、加热器24、第一换热组件8、第一泵21、第一流量调节装置11、第一支路10连通形成回路。加热器24可以是电加热器或PTC加热器，用于对流经加热器24的冷却液进行加热。例如，冬季环境温度比较低的时候，汽车启动前，需要使电池的工作温度达到一定要求，因此，可以通过开启加热器24，使冷却液升温，冷却液流经第一换热组件8时与电池周围环境进行热交换，释放热量以提升电池周围环境温度，使电池具有合适的工作温度。
冬季环境温度比较低的时候，热管理系统可以开启制热模式对车厢进行制热。然而，汽车刚启动时，冷却液温度相对较低，在制热模式下，制冷剂通过第一换热器7吸收冷却液的热量比较有限，热管理系统制热效果不佳或不能快速制热。此时，热管理系统可以开启加热器24，主动加热冷却液并通过第一换热器7提供热量给制冷剂。如此，热管理系统通过加热器24不仅可以提供热量给制冷剂侧以提升制热效果，还可以用于对车厢内环境进行快速制热，还可以对电池和电机进行预热。在本实施例中，电加热24连接于第一换热组件8和第一换热部71之间，对电池进行优先预热。在其它实施例中，加热器24可以连接于第一换热部71与第一换热组件8之间，也可以连接于第一支路10上，加热器24的位置还可以是图5中冷却液流动路线上任一位置。需要说明的是，在其它模式中，加热器24可以选择不开启，加热器24仅作为导通的流路使用。
