具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本申请,而不能理解为对本申请的限制。
下面参考图1-图5描述根据本申请实施例的热管理系统100。
根据本申请实施例的热管理系统100,包括电池换热模组和控制器,电池换热模组包括:第一干路10a和第二干路10b,第一干路10a中设置有第一换热组件21,第二干路10b中设置有第二换热组件22,第一换热组件21和第二换热组件22用于与电池换热。
本申请的热管理系统100用于车辆,其中,车辆可以是燃油汽车、或燃气汽车、或新能源汽车、或轨道车辆,新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。热管理系统100中的电池换热模组适于与车辆的 电池换热。电池可以用于车辆的供电,例如,电池可以作为车辆的操作电源,或者电池可以作为车辆的驱动电源,以代替或部分地代替燃油或天然气等为车辆提供驱动动力,或者电池可以用于为车辆的某些部件比如马达等供电,使得电池可以用于车辆的启动、导航和行驶等中的至少一个的工作用电需求。
第一换热组件21和第二换热组件22可与电池换热,以调节电池的温度,以便于电池具有合适的工作温度,从而保证电池的工作稳定、可靠。比如,在冬天环境温度较低时,可对电池进行加热,提升电池的启动速度。还比如,在夏天环境温度过高,或者电池工作温度较高时,可对电池进行降温,提升电池工作安全性,延长电池的工作寿命。
本申请热管理系统100还包括控制器,控制器被配置为根据电池的温度,控制第一干路10a和第二干路10b中的至少一个与电池换热。而第一换热组件21设置在第一干路10a中,第二换热组件22设置在第二干路10b中,因此控制器可控制第一换热组件21和第二换热组件22中的一个与电池换热。第一干路10a和第二干路10b中流通的工质可以相同也可以不同。工质可以是水,也可以是除水以外的其他液态工质,还可以是二氧化碳、冷媒等其他可以进行相态变化的介质。例如:第一干路10a流通的是液态工质,第二干路10b中流通的可以进行相态变化的介质。例如:第一干路10a可以与高压冷却系统连接或者发动机冷却系统,流通高压冷却系统或者发动机冷却系统中的冷却液,第二干路10b与空调系统连接,流通空调系统中进行相态变化的介质。
控制器可控制第一换热组件21与电池换热,控制器还可控制第二换热组件22与电池换热,控制器还可控制第一换热组件21和第二换热组件22均与电池换热,可根据电池的实际需要进行选择。
例如:请参阅图8,图8为本申请的电池包的一实施方式示意图,电池包包括电池、第一换热组件21和第二换热组件22,电池设置于第一换热组件21和第二换热组件22之间。第一换热组件21设置于电池的一侧(上方),第二换热组件22设置电池另一侧(下方),第一换热组件为电池上盖,第二换热组件为电池的底板。当电池需要很大的换热量时,可以让第一干路10a和第二干路10b同时换热,当电池需要的换热量较小时,可以让第一干路10a和第二干路10b中的一个换热。第一换热组件21设置于电池的一侧,第二换热组件22设置于电池的另一侧,当电池的一侧的发热量高于电池的正产工作温度时,控制器控制与该侧对应的换热组件对电池进行冷却。
当电池需要很大的换热量时,可以让第一干路10a和第二干路10b同时换热,当电池需要的换热量较小时,可以让第一干路10a和第二干路10b中的一个换热。第一换热组件21设置于电池的一侧,第二换热组件22设置于电池的另一侧,当电池的一侧的发热量高于电池的正产工作温度时,控制器控制与该侧对应的换热组件对电池进行冷却。
还可以根据电池的温度,选择第一干路10a和第二干路10b中的至少一个与电池换热。根据电池的温度,当第一干路10a和第二干路10b并联(如图4所示)时,控制进入第一干路10a和第二干路10b中的工质的量,灵活对电池加热,节约能量。
第一换热组件21和第二换热组件22为相互独立的组件,可相互独立工作,第一干路和第二干路具备不同的换热模式。第一换热组件21和第二换热组件22设置于电池的不同区域时,第一换热组件21和第二换热组件22的换热效果可以是相反地,比如第一换热组件21对电池加热,同时第二换热组件22对电池降温,以使电池的温度均匀。电池换热模组热管理模式包括:第一干路和第二干路同时加热或者同时冷却、第一干路和第二干路中的一个加热一个冷却,根据电池不同区域温度,适配不同的热管理模式,以使电池的温度均匀。
例如:请参阅图6和图7,图6为本申请的电芯的第一实施方式的示意图,图7为本申请的电芯的第二实施方式的示意图。电池包括多个电芯,多个电芯在电池中排布,电芯301的两端设置有电极也可以是电芯301的一端设置有电极,电芯301在工作时,电极会产生大量的热量,电极附近的区域为电极发热区域,远离电极的区域为非电极发热区。通常情况下,电池300在工作时,电极会产生大量的热量,使电极附近的区域的温度高压远电极区域的温度。在电池的一侧或者两侧,电极发热温度区域301b均对应设置第一换热组件21,第二换热组件22设置于电池的非电极发热温度区域301a。当电极发热温度区域301b温度高于电池的工作温度时,第一换热组件21对电极发热温度区域301b进行冷却。当电池的非电极发热温度区域301a温度低于电池的工作温度时,第二换热组件22对电池的非电极发热温度区域301a进行加热。
例如,在一种工况下,第一换热组件21或者第二换热组件22单独与电池换热的效率可以低于第一换热组件21和第二换热组件22共同与电池换热的效率。并且第一换热单元和第二换热单元对电池的换热效率也可能是不同的。因此通过设置控制器可使第一换热组件21或第二换热组件22,或者第一换热组件21与第二换热组件22组合与电池进行换热,电池换热模组以不同的效率与电池进行换热。根据电池的温度,使电池换热模组以合适的效率与电池换热,可降低热管理系统100的能耗,提升热管理系统100的功能性。
需要进行说明的是,第一换热组件21和第二换热组件22可以是同一个换热板上的不同管路对应的区域(如图5所示),也就是说第一换热组件21中的管路和第二换热组件22中的管路可以位于同一换热板。
第一换热组件21和第二换热组件22也可以是分开的组件。
第一换热组件21和第一换热组件22可以位于电池的同侧。可以根据电池各处的温度,选择第一换热组件21和第一换热组件22中的至少一个换热,实现电池同侧不同区域的温度控制,提升电池的均温性,提升电池性能。
第一换热组件21和第一换热组件22可以位于电池的不同侧。相比于位于电池的同侧,设置在电池的不同侧,对电池的不同加热,可以进一步提升电池的均温性,提升电池性能。
第一换热组件21和第二换热组件22可以是与电池的电芯接触,直接对电芯换热,例如第一换热组件21和第二换热组件22可以是电池的上盖,第一换热组件21和第二换热组件22可以是电池下盖。
第一换热组件21和第二换热组件22可以是与电池包接触,从而对间接对电芯换热。
根据本申请实施例的热管理系统100,通过设置第一换热组件21和第二换热组件22,并且设置控制器控制第一换热组件21和第二换热组件22中的至少一个与电池换热,电池换热模组以不同的效率或者不同热管理模式与电池进行换热。控制器根据电池的温度,使电池换热模组以合适的效率或者不同热管理模式与电池换热,可降低热管理系统100的能耗,提升热管理系统100的功能性。
在本申请的一些实施例中,第一换热组件21设置于电池的电极发热区域,第二换热组件22设置于电池的非电极发热区域,从而提升电池的均温性,提升电池性能。

热管理系统100还包括空调循环回路101,空调循环回路101适于对乘员舱进行换热。比如,在冬天环境温度较低时,空调循环回路101可对乘员舱进行加热,在夏天环境温度过高时,空调循环回路101可对乘员舱进行降温,提升用户使用舒适性。空调循环回路101包括:冷却支路和加热支路,空调循环回路101的冷却支路用于与乘员舱换热,以制冷乘员舱,空调循环回路101的加热支路用于与乘员舱换热,以加热乘员舱。可选地,工质在空调循环回路101中循环流动,即在加热制冷和冷却支路内循环流动,以适于对乘员舱加热或制冷。
冷却支路与第一干路10a和第二干路10b均并联,同时加热支路与第一干路10a和第二干路10b均并联,因此冷却支路、加热支路、第一干路10a和第二干路10b均相互独立工作,对乘员舱换热与对电池换热相互之间不冲突。

在本申请的一些实施例中,热管理系统100还包括:存储装置,存储装置连接在压缩机11的排气口与压缩机11的进气口之间。
压缩机11工作时,工质从压缩机11的进气口流入,低温低压的气态工质被压缩机11压缩后变成高温高压的气态工质,并从压缩机11的排气口流出,工质可在进行热交换后再次流回压缩机11,完成一次循环。
存储装置连接在压缩机11的排气口和压缩机11的进气口之间,存储器构造为可存储工质且将存储的工质排出。可以理解的是,工质热交换进行制热时,工质热交换进行制冷时,工质相态不一样,而在相同质量下,气态工质的体积大于液态工质的体积,导致加热时的工质需求量与冷却时的工质需求量不一样。通过设置存储器可将工质存储并且可将存储的工质排出,可根据电池的温度对工质量进行补充或者减少。
可以理解的是,液态工质更便于存储,因此在本申请的一些实施例中,存储器构造为工质可在存储器放热液化,并且存储器可存储液态工质。存储器连接在压缩机11的排气口与压缩机11的进气口之间,存储器可将从压缩机11的排气口流出的工质液化后存储在存储器内部。

工质对电池进行加热时,与对电池进行冷却时,工质的相态不一样,而在相同质量下,气态工质的体积大于液态工质的体积,导致对电池进行加热时的工质需求量高于对电池进行冷却时的工质需求量。在电池换热模组对电池制热时,控制器控制存储器放出存储的工质,补充到第一干路10a或/和第二干路10b中,满足对电池进行加热时的工质需求量;在电池换热模组对电池制冷时,存储器存储流经的工质,降低第一干路10a或/和第二干路10b中的工质量,满足对电池进行制冷时的工质需求量。
在本申请的一些具体实施例中,存储器构造为储液干燥器,储液干燥器被构造成可存储液态工质且将存储的液态工质排出。储液干燥器还可过滤掉工质中的水分和杂质,避免损坏或堵塞工质管路,延长工质管路的使用寿命,使工质顺畅流动。
在本申请的一些实施例中,空调循环回路101包括:压缩机11、第一换热器12和第二换热器13,压缩机11包括进气口和排气口,压缩机11的排气口、第一换热器12、第二换热器13和压缩机11的进气口依次连接。
在空调循环回路101工作时,工质从压缩机11的进气口流入,低温低压的气态工质被压缩机11压缩后变成高温高压的气态工质,并从压缩机11的排气口流出。第一换热器12的第一端口与压缩机11的排气口连接,第一换热器12的第二端口与第二换热器13连接,第二换热器13与压缩机11的进气口连接。因此工质从压缩机11流出后流经第一换热器12后,再流经第二换热器13,并且在经过其他热交换后,最后回到压缩机11,形成工质回路,完成一次循环。
加热支路包括第一换热器12,第一干路10a与第一换热器12并联,第二干路10b与第一换热器12并联,控制器用于控制压缩机11的排气口与第一换热器12、第一干路10a和第二干路10b中的至少一个连通,以实现第一换热器12、第一干路10a和第二干路10b中的至少一个换热。
加热支路与第一干路10a并联,加热支路与第二干路10b并联,在加热支路上的第一换热器12和在第一干路10a上的第一换热组件21,以及在第二干路10b上的第二换热组件22均相互并联,第一换热器12、第一换热组件21和第二换热组件22相互独立工作。
压缩机11的排气口可选择地与加热支路、第一干路10a和第二干路10b中的至少一个连接,而从压缩机11的排气口流出的工质为高温高压的气态工质,因此压缩机11的排气口与加热支路、第一干路10a和第二干路10b中的一个连接时,加热支路、第一干路10a和第二干路10b制热。

在本申请的一些实施例中,第一换热组件21和第二换热组件22中的至少1个包括多个换热组件,多个换热组件并联。通过设置多个换热组件可提升与电池换热的面积,进一步提升对电池的换热效率。
在本申请的一些实施例中,并联的多个换热组件中的一个设置于电池的电极发热区域,另一个换热组件设于电池的非电极发热区域。
在本申请的一些实施例中,一个换热组件设置于电池的电极发热区域,一个换热组件设置于电池的非电极发热区域。
控制器可根据电池的温度,控制设置于电池的电极发热区域的换热组件大幅度制冷,控制设置于电池的非电极发热区域的换热组件小幅度制冷。或者控制器可根据电池的温度,控制设置于电池的电极发热区域的换热组件制冷,控制设置于电池的非电极发热区域的换热组件制热。
进一步地,第一换热组件和第二换热组件设于电池的同一侧,一个换热组件设置于电池的电极发热区域,另一个换热组件设置于电池的非电极发热区域。
从而可以根据电池各处的温度,选择开启位于电池的电极发热区域和位于电池的非电极发热区域的换热组件中的至少一个,实现电池同侧不同区域的温度控制,提升电池的均温性,提升电池性能。例如:电极发热区域的温度远高于非电极发热区域时,可以开启电极发热区域应的换热组件对电池冷却;或者开启电极发热区域应的换热组件对电池冷却的同时,开启非电极发热区域应的换热组件对电池冷却,但电极发热区域应的换热组件的工质的量大于非电极发热区域应的电池换热组件的工质的量,这样可以提升电池的均温性。

在本申请的一些具体实施例中,热管系统还包括高压热管理子系统201,高压热管理子系统201包括第四换热器71和冷却液循环系统,第四换热器71包括第一流道和第二流道,第一流道与冷却液循环系统连接,第二流道的一端选择性的与第二端和第一换热器12连通,第二流道的另一端与第四换热器71连接。
在本申请的一些实施例中,高压热管理子系统201还包括:充配电/电机总成72和第一散热器73,充配电/电机总成72与车辆的电机电控进行热交换,充配电/电机总成72连接在冷却液循环系统和第一散热器73之间。第一散热器73适于与车外环境进行热交换。
在本申请的一些实施例中,高压热管理子系统201还包括:切换阀组74,切换阀组74分别与循环回路的两端、充配电/电机总成72和第一散热器73相连,切换阀组74动作以使得高压热管理子系统201不同工况之间进行切换。具体地,切换阀组74为三通阀。
切换阀组74可控制冷却液的流动方向,可将车辆的电机电控产生的热量加热工质,或者可将车辆的电机电控产生的热量通过第一散热器73逸散到车外。
在本申请的一些实施例中,高压热管理系统100还包括水泵75,水泵75设置在充配电/电机总成72和第四换热器71之间,水泵75构造为将冷却液从充配电/电机总成72泵向第四换热器71。
高压热管理子系统201具有第一工况,在第一工况下,充配电/电机总成72和第二流道形成第一回路。从充配电/电机总成72流出的冷却液在水泵75的作用下流向第四换热器71,冷却液在第四换热器71的第二流道中与第一流道中的工质换热后,流回充配电/电机总成72与车辆的电机电控进行热交换。
工质循环回流有吸热需求,同时高压热管理子系统201无散热需求时,高压热管理子系统201可按第一工况运行。从充配电/电机总成72流出的高温冷却液流入第二流道,与流经第一流道的低温工质进行热交换,将车辆的电机电控产生的热量传递到工质循环回流,车辆的电机电控产生的热量进行了有效利用,提升了热管理系统100的加热能力的同时还可降低热管理系统100的能耗。
高压热管理子系统201还具有第二工况,在第二工况,充配电/电机总成72、第一散热器73和第二流道形成第二回路。从充配电/电机总成72流出的冷却液在水泵75的作用下流向第四换热器71,冷却液在第四换热器71的第二流道中与第一流道中的工质换热后,流向第一散热器73,冷却液在第一散热器73进行热交换后,流回充配电/电机总成72与车辆的电机电控进行热交换。
工质循环回流有吸热需求,同时高压热管理子系统201有散热需求,且高压热管理子系统201的散热需求高于工质循环回流的吸热需求时,高压热管理子系统201可按第二工况运行。从充配电/电机总成72流出的高温冷却液流入第二流道,与流经第一流道的低温工质进行热交换,将车辆的电机电控产生的热量传递到工质循环回流,而冷却液的温度在经过一次热交换后还是较高,因此冷却液即系流向第一散热器73,与车外环境进行第二次热交换,进行散热。车辆的电机电控产生的热量进行了有效利用,提升了热管理系统100的加热能力的同时还可降低热管理系统100的能耗。
除此之外,工质循环回流有吸热需求,同时高压热管理子系统201产生的热量不足,且冷却液的温度低于车外环境的温度时,高压热管理子系统201也可按第二工况运行。冷却液在第一散热器73与车外环境进行热交换,提升冷却液的温度,冷却液再经过循环回路流向充配电/电机总成72和第四换热器71,与流经第一流道的低温工质进行热交换,将车外环境的热量传递到工质循环回流以及高压热管理子系统201。可对热量进行有效利用,提 升了热管理系统100的加热能力的同时还可降低热管理系统100的能耗。
高压热管理子系统201还包括混合工况,在混合工况,第一回路和第二回路同时循环。从充配电/电机总成72流出的冷却液在水泵75的作用下流向第三换热器14,冷却液在第三换热器14的第二流道中与第一流道中的工质换热后,部分直接流回充配电/电机总成72与车辆的电机电控进行热交换,另外部分流向第一散热器73,冷却液在第一散热器73进行热交换后,流回充配电/电机总成72与车辆的电机电控进行热交换。
工质循环回流有吸热需求,同时高压热管理子系统201有散热需求,且工质循环回流的吸热需求高于高压热管理子系统201的散热需求时,高压热管理子系统201可按混合工况运行。
从充配电/电机总成72流出的高温冷却液流入第二流道,与流经第一流道的低温工质进行热交换,将车辆的电机电控产生的热量传递到工质循环回流,经过热交换的冷却液部分流回充配电/电机总成72,另外与部分冷却液即流向第一散热器73,与车外环境进行第二次热交换,进行散热。车辆的电机电控产生的热量进行了有效利用,提升了热管理系统100的加热能力的同时还可降低热管理系统100的能耗。
高压热管理子系统201具有第一工况、第二工况和混合工况,而第一工况、第二工况和混合工况循环回流中的冷却剂均对工质循环回流中的工质加热。因此热管理系统100在不同工况下工作还可配合高压热管理子系统201的不同工况进行工作。
比如,在仅有乘员舱采暖的工况时,可与高压热管理子系统201的第一工况、第二工况和混合工况相互配合。
在本申请的一些实施例中,热管系统还包括发动机热管理子系统202,所述发动机热管理子系统202包括第五换热器76和冷却液循环系统,所述第五换热器76包括第三流道和第四流道,所述第三流道与所述冷却液循环系统连接,所述第四流道的一端选择性的与所述第二端b和所述第一换热器124连通,所述第四流道的另一端与所述第三换热器1433连接。
在本申请的一些实施例中,发动机热管理子系统202还包括:发动机总成77和第二散热器78,发动机总成77与车辆的发动机进行热交换,发动机总成77连接在冷却液循环系统和第二散热器78之间。第二散热器78适于与车外环境进行热交换。
根据本申请实施例的车辆1000,包括上述任一项的热管理系统100。
根据本申请实施例的车辆1000,通过设置上述热管理系统100,可以减少维修、更换电池的次数,提升车辆的充电效率和使用便利性,同时便于实现车辆的合理化布局。
