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67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:压缩机11、第一换热器12和换热组件2,压缩机11的排气口与换热组件2连接,第一换热器12的第一端口与压缩机11的进气口连接,第一换热器12的第二端口与换热组件2连接。换热组件2包括并联设置的第一换热板21和第二换热板22,第一换热板21和第二换热板22分别用于调节电池模组的温度。
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;车辆还包括电池模组,电池模组可以用于车辆的供电,例如,电池模组可以作为车辆的操作电源,或者电池模组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,或者电池模组可以用于为车辆的某些部件比如马达等供电,使得电池模组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。
在热管理系统100工作时,冷媒从压缩机11的进气口流入,低温低压的气态冷媒被压缩机11压缩后变成高温高压的气态冷媒,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的进气口连接,第一换热器12的第二端口与换热组件2连接。因此冷媒从压缩机11流出后流经换热组件2后,再流经第一换热器12,最后回到压缩机11,形成冷媒回路,完成一次循环。
由压缩机11、换热组件2和第一换热器12共同形成冷媒回路,可以理解的是,冷媒回路中还包括节流件等其他元件,但是为了简化方案的描述和便于理解,在描述冷媒回路时只选择用压缩机11和换热件来限定冷媒回路。
在由压缩机11、换热组件2和第一换热器12共同形成的冷媒回路中,从压缩机11的排气口流出的高温高压的气态冷媒在换热组件2处进行热交换,冷媒放热液化,随后冷媒经过节流降压后经过第一换热器12,在第一换热器12处吸热汽化,最终变为低温低压的气态冷媒从压缩机11的进气口流入。
而换热组件2包括并联设置的第一换热板21和第二换热板22,因此在由压缩机11、换热组件2和第一换热器12共同形成的冷媒回路中,冷媒直接流过第一换热板21和第二换热板22,在第一换热板21和第二换热板22处放热,与电池模组进行热交换,从而实现对电池模组的加热,以便于使得电池模组具有合适的工作温度,从而保证电池模组工作稳定、可靠。比如,在冬天环境温度较低时,可对电池模组进行加热,提升电池模组的启动速度。
除此之外,本申请的热管理系统100还包括其他元件,在压缩机11、换热组件2和其他元件共同形成的冷媒回路中,还可控制冷媒在换热组件2处吸热,与电池模组进行热交换,从而实现对电池模组的制冷,以便于使冷得电池模组具有合适的工作温度,从而保证电池模组工作稳定、可靠。比如,在夏天环境温度过高,或者电池模组工作温度较高时,可对电池模组进行降温,提升电池模组工作安全性,延长电池模组的工作稳定性。
本申请的换热组件2包括第一换热板21和第二换热板22,第一换热板21和第二换热板22可对电池模组的不同端面接触换热,以调节电池模组的温度,可提升换热效率,使电池模组快速达到合适的工作温度。并且,冷媒直接在第一换热板21和第二换热板22内部流动,而第一换热板21和第二换热板22直接与电池模组接触换热,不但可降低布置难度,并且可提升换热效率,使电池模组快速达到合适的工作温度,提升电池模组的工作稳定性。
根据本申请实施例的热管理系统100,通过设置第一换热板21和第二换热板22对电池模组进行热交换,可对电池模组的不同端面直接接触热交换,不但可降低布置难度,并且可提升换热效率,使电池模组快速达到合适的工作温度,提升电池模组的工作稳定性,提升热管理系统100的工作效率。
在本申请的一些实施例中,如图1所示,热管理系统100还包括第二换热器13,所述第二换热器13的第一端口与所述压缩机11的排气口连接,所述第二换热器13的第二端与所述换热组件2连接,所述换热组件2与所述压缩机11的进气口连通。
在由压缩机11、第二换热器13和换热组件2共同形成的冷媒回路中,从压缩机11的排气口流出的高温高压的气态冷媒在第二换热器13处进行热交换,冷媒放热液化,随后冷媒经过节流降压后经过换热组件2,在换热组件2处吸热汽化,最终变为低温低压的气态冷媒从压缩机11的进气口流入。冷媒在流经换热组件2处吸热,换热组件2与电池模组进行热交换,从而实现对电池模组的制冷,以便于使得电池模组具有合适的工作温度,从而保证电池模组工作稳定、可靠。
在本申请的一些实施例中,压缩机11的排气口选择性地与换热组件2或第二换热器13的第一端口连通,压缩机11的进气口选择性地与第一换热器12的第一端口或换热组件2连通。
压缩机11、换热组件2和第一换热器12可共同形成一个冷媒回路,压缩机11、换热组件2和第二换热器13也可共同形成一个冷媒回路,通过使压缩机11的排气口和进气口可选择性地连通可控制冷媒的流动,一个元件在不同的冷媒回路中可起到不同的作用,降低元件的布置数量,降低制造成本且降低布置难度。
当压缩机11的排气口与换热组件2连通,且压缩机11的进气口与第一换热器12的第一端口连通时,冷媒在换热组件2处放热,在第一换热器12处吸热,即可满足换热组件2制热且第一换热器12制冷。
当压缩机11的排气口与第二换热器13的第一端口连通,且压缩机11的进气口与换热组件2连通时,冷媒在第二换热器13处放热,在换热组件2处吸热,即可满足换热组件2制冷且第二换热器13制热。
在本申请的一些实施例中,压缩机的排气口与第一换热器的第二端口连接;压缩机的排气口选择性地与第一换热器的第二端口或换热组件连通,压缩机的进气口选择性地与换热组件或第一换热器的第一端口连通,从而使得一个第一换热器即可实现电池模组的制热和制冷。
在空调循环回路工作时,冷媒从压缩机的进气口流入,低温低压的气态冷媒被压缩机压缩后变成高温高压的气态冷媒,并从压缩机的排气口流出。因此第一换热器与压缩机的排气口连接,冷媒可在第一换热器处放热。而压缩机的排气口可与第一换热器连通,压缩机的排气口还可与换热组件2连通。热管理系统100可控制冷媒流向第一换热器或者流向换热组件,以使冷媒在第一换热器放热,或者在换热组件2处放热。
同理地,压缩机的进气口可选择地与换热组件或第一换热器的第一端口连通,冷媒可经过换热组件流回压缩机,冷媒还可经过第一换热器流回压缩机,或当压缩机的排气口与换热组件连通时,电池模组实现制热,当压缩机的排气口与第一换热器连通时,电池模组实现制冷。
在本申请的一些实施例中,如图1所示,热管理系统100还包括存储器14,存储器14连接在压缩机11的排气口与压缩机11的进气口之间。
可以理解的是,换热组件2对电池模组进行加热时,与对电池模组进行冷却时,在换热组件2中的冷媒物态不一样,而在相同质量下,气态冷媒的体积大于液态冷媒的体积,导致对电池模组进行加热时的冷媒需求量高于对电池模组进行冷却时的冷媒需求量。

在本申请的一实施例中,存储器14构造为储液干燥器,储液干燥器的进口端与第二换热器13的第二端连接,储液干燥器的出口端与换热组件2连接,储液干燥器被构造成可存储液态冷媒且将存储的液态冷媒排出。储液干燥器连接在第二换热器13和换热组件2之间,从第二换热器13流出的冷媒可被存储在储液干燥器中,储液干燥器中存储的冷媒还可流向换热组件2。
除此之外,储液干燥器还可过滤掉冷媒中的水分和杂质,避免损坏或堵塞冷媒管路,延长冷媒管路的使用寿命,使冷媒顺畅流动。
在本申请的另一些实施例中,存储器14构造为冷媒可在存储器14放热液化,并且存储器14可存储液态冷媒。存储器14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14可将从压缩机11的排气口流出的冷媒液化后存储在存储器14内部。
在本申请的一些实施例中,热管理系统100还包括第四换热器,第四换热器连接在存储器14与压缩机11的排气口之间。第四换热器对冷媒热交换,冷媒可在第四换热件处放热液化,液态冷媒继续将存储器14流动,并可存储在存储器14中。

可以理解的是,电池模组的工作安全较高,而在第一换热板21和第二换热板22内布置的流路流径有限,直接将压力较大的冷媒通向第一换热板21和第二换热板22,第一换热板21和第二换热板22具有被高压冷媒冲击破损的风险,冷媒从第一换热板21或第二换热板22流出会危害电池模组的工作安全性。因此本申请在排气口和换热组件2之间设置有第一阀组3,冷媒在流经换热组件2时首先经过第一阀组3的节流降压,冷媒的压力降低后再流经第一换热板21和第二换热板22,提升第一换热板21和第二换热板22的工作稳定性,保证电池模组的安全性。

在本申请的一些实施例中,如图1所示,热管理系统100还包括气液分离器16,气液分离器16与压缩机11的进气口连通。冷媒在经过节流蒸发后变为低温低压的气态冷媒,由于蒸发吸热并不能完全保证将所有的冷媒均转变为气态冷媒,因此在冷媒重新流入压缩机11之前要先流入气液分离器16中,气液分离器16将气态冷媒和液态冷媒分离,只驱动低温低压的气态冷媒流向压缩机11,防止液滴对压缩机11内的功能件的液击,保证压缩机11安全正常运转。
在本申请的一些实施例中,热管理系统100还包括控制阀组,控制阀组设置在冷媒循环回路101上,控制阀组动作以使得排气口的冷媒流向车外冷凝器130或换热组件2。通过设置控制阀组,可控制冷媒的流向,以控制热管理系统100的工作。

在本申请的一些实施例中,如图6所示,热管理系统100包括第一排气流道10a,第二节流阀组通过第一排气流道10a与进气口相连,流经换热组件2的冷媒可经过第一排气流道10a流回进气口。比如在对电池模块制冷时,冷媒从排气口流出,经过车外冷凝器130放热后,进入到换热流道10e在换热组件2处吸热,然后经过第一排气流道10a流回进气口。
热管理系统100还包括与排气口相连的第二排气流道10b,第二排气流道10b连接至第一排气流道10a,因此第二节流阀组也就通过第二排气流道10b与排气口相连,冷媒可经由第二排气流道10b流向换热组件2。比如在对电池模块制热时,冷媒从排气口流出,经过第二换热流道10g流向换热组件2,在换热组件2处放热。

第一通断阀61可控制第二排气流道10b的通断,以控制冷媒从排气口是否流向换热组件2,第一通断阀61关闭时阻止冷媒流向换热组件2。第三通断阀63可控制第三排气流道10c的通断,以控制冷媒从排气口是否流向车外冷凝器130,第三通断阀63关闭时阻止冷媒流向车外冷凝器130。
如图1所示,第一排气流道10a与回气口相连,第二排气流道10b与排气口相连,第二排气流道10b连接至第一排气流道10a,在第一通断阀61控制第二排气流道10b流通时,从排气口流出的冷媒会从第二排气流道10b流向第一排气流道10a,继而直接流回回气口。因此通过在第一排气流道10a设置第二通断阀62,第二通断阀62可控制第一排气流道10a的通断,第二通断阀62关闭时阻止第二排气流道10b的冷媒流向进气口。

蒸发器120还可对冷媒起到蒸发汽化的作用,冷媒在蒸发器120处吸热液化,液态的冷媒转变为气态冷媒,气态冷媒再被输送进回气口,防止液滴对压缩机11内的功能件的液击,保证压缩机11安全正常运转。

可以理解的是,冷媒可同时在多个冷媒回路内流动,而多个冷媒回路之间会相互连通甚至相互具有重合部分,因此本申请的热管理系统100还设置有多个阀,避免在多个不同冷媒回路内流动的冷媒之间相互干扰,降低热管理系统100的工作效率。
在本申请的一些实施例中,热管理系统100还包括第一开关阀,第一开关阀设置在换热组件2与第三换热器81之间。第一开关阀可控制冷媒从换热组件2流向第三换热器81,提升冷媒的流动性,提升热管理系统100的工作稳定性。

同理地,在车外冷凝器130的第二端还设置有第四单向阀74,第四单向阀74构造为冷媒从车外冷凝器130的第二端流出,而冷媒不能从车外冷凝器130的第二端流入。当冷媒在压缩机11、车外冷凝器130和蒸发器120共同形成的冷媒回路中流动,且同时冷媒在压缩机11、蒸发器120和换热组件2共同形成的冷媒回路中流动时,从车外冷凝器130流出的冷媒,和对电池模组制热后从换热组件2流出的冷媒汇集后再经过节流蒸发等处理后流回压缩机11。通过设置第一单向阀71可使避免从换热组件2流出的冷媒流向车外冷凝器130,可提升冷媒的流动性。
在本申请的一些实施例中,热管理系统100还包括第二开关阀,第二开关阀设置在换热组件2与第二换热器13的第二端口之间。第二开关阀可控制冷媒从第二换热器13流向换热组件2,提升冷媒的流动性,提升热管理系统100的工作稳定性。

当冷媒在压缩机11、换热组件2和车外冷凝器130共同形成的冷媒回路中流动时,第二单向阀72可控制冷媒从第二换热器13流向换热组件2。
可以理解的是,第一单向阀71和第二单向阀72的作用互补,若只设置第一单向阀71,则冷媒无法经过车外冷凝器130流向换热组件2,若只设置第二单向阀72,则压缩机11、蒸发器120和换热组件2共同形成的冷媒回路无法导通,因此同时设置有第一单向阀71和第二单向阀72可使冷媒有序流动,提升热管理系统100的工作稳定性。
在本申请的另一些实施例中,在换热组件2与第二换热器13和第一换热器12的连接端之间设置有双向阀,可控制冷媒从第一换热器12流向换热组件2,还可控制冷媒从换热组件2流向第一换热器12。

可以理解的是,压缩器对冷媒加压做功,以使冷媒温度提升,冷媒可在冷媒回路中放热。而当热管理系统100对冷媒放热的需求较大时,可将冷媒在小循环回流中玄幻流动,压缩机11对冷媒对此加压做功,提升冷媒的温度,可使冷媒放出大量的热,提升热管理系统100的制热能力。
在本申请的一些实施例中,如图2所示,热管理系统100还包括:高压热管理子系统1001,高压热管理子系统1001包括第三换热器81及循环回路102,第三换热器81具有第一流道81a及第二流道81b,第一流道81a的第一端口与换热组件2及车内冷凝器15的第二端连接,第一流道81a的第二端口与第一换热器12的第二端口连接。第二流道81b设置在循环回路102上,循环回路102用于与高压热管理子系统1001换热。

冷却液在循环回路102中流动,可第一散热器82热交换后流动至第二流道81b中再与冷媒进行热交换,从而利用车辆的电机电控产生的热量加热冷媒,或者对冷媒进行冷却,利用冷媒的热量加热电机电控。
而第一流道81a的第一端口可选择地与换热组件2和车内冷凝器15的第二端中的至少一个连接,第一流道81a的第二端口可选择地与车外冷凝器130的第二端和蒸发器120的第二端中的至少一个连接。冷媒在流经第三换热器81时也可进行换热,因此第三换热器81也可与其他元件共同形成冷媒回路。
下面参考图3-图18,简单描述几个热管理系统100在不同工况下工作的实施例。

上述的几个实施例仅是为了便于描述本申请和简化描述,而不是指示或暗示热管理系统100在某种工况下仅能按实施例所示情况运行,因此不能理解为对本申请的限制。
在本申请的一些实施例中,如图2所示,高压热管理子系统1001还包括:切换阀组84,切换阀组84分别与循环回路102的两端、第一散热器82和第二散热器83相连,切换阀组84动作以使得高压热管理子系统1001在第一工况、第二工况之间进行切换。
切换阀组84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冷媒,或者可将车辆的电机电控产生的热量通过第二散热器83逸散到车外。
在本申请的一实施例中,如图2所示,切换阀组84为四通水阀,四通水阀包括相互连通的第一阀门841、第二阀门842、第三阀门843和第四阀门844,第一阀门841与第三换热器81相接,第二阀门842与第一散热器82连接,第三阀门843与第二散热器83连接,第四阀门844连接在第一散热器82和第二散热器83之间。
在本申请的一些实施例中,高压热管理系统100还包括水泵85,水泵85设置在第一散热器82和第三换热器81之间,水泵85构造为将冷却液从第一散热器82泵向第三换热器81。
如图19所示,高压热管理子系统1001具有第一工况,在第一工况下,第一散热器82和第二流道81b形成第一回路。此时四通水阀的第一阀门841和第四阀门844打开,第二阀门842和第三阀门843关闭。
从第一散热器82流出的冷却液在水泵85的作用下流向第三换热器81,冷却液在第三换热器81的第二流道81b中与第一流道81a中的冷媒换热后,流回第一散热器82与车辆的电机电控进行热交换。
冷媒循环回路101有吸热需求,同时高压热管理子系统1001无散热需求时,高压热管理子系统1001可按第一工况运行。从第一散热器82流出的高温冷却液流入第二流道81b,与流经第一流道81a的低温冷媒进行热交换,将车辆的电机电控产生的热量传递到冷媒循环回路101,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。
如图21所示,高压热管理子系统1001还具有第二工况,在第二工况,第一散热器82、第二散热器83和第二流道81b形成第二回路。此时四通水阀的第一阀门841和第三阀门843打开,第二阀门842和第四阀门844关闭。
从第一散热器82流出的冷却液在水泵85的作用下流向第三换热器81,冷却液在第三换热器81的第二流道81b中与第一流道81a中的冷媒换热后,流向第二散热器83,冷却液在第二散热器83进行热交换后,流回第一散热器82与车辆的电机电控进行热交换。
冷媒循环回路101有吸热需求,同时高压热管理子系统1001有散热需求,且高压热管理子系统1001的散热需求高于冷媒循环回路101的吸热需求时,高压热管理子系统1001可按第二工况运行。从第一散热器82流出的高温冷却液流入第二流道81b,与流经第一流道81a的低温冷媒进行热交换,将车辆的电机电控产生的热量传递到冷媒循环回路101,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二散热器83,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,冷媒循环回路101有吸热需求,同时高压热管理子系统1001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1001也可按第二工况运行。冷却液在第二散热器83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102流向第一散热器82和第三换热器81,与流经第一流道81a的低温冷媒进行热交换,将车外环境的热量传递到冷媒循环回路101以及高压热管理子系统1001。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。
如图22所示,高压热管理子系统1001还具有第三工况,在第三工况,第一散热器82和第二散热器83形成第三回路。此时四通水阀的第二阀门842和第三阀门843打开,第一阀门841和第四阀门844关闭。
从第一散热器82流出的冷却液在水泵85的作用下流向第二散热器83,冷却液在第二散热器83中与车外环境换热后,流回第一散热器82与车辆的电机电控进行热交换。
在冷媒循环回路101不需要从冷却液吸热时,那么不管高压热管理子系统1001是否有散热需求,高压热管理子系统1001则按第三工况运行。从第一散热器82流出的高温冷却液直接流向第二散热器83,与车外环境进行热交换,车辆的电机电控产生的热量散热到车外环境,高压热管理子系统1001快速散热。
如图20所示,高压热管理子系统1001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。此时四通水阀的第一阀门841、第三阀门843和第四阀门844打开,第二阀门842关闭。
从第一散热器82流出的冷却液在水泵85的作用下流向第三换热器81,冷却液在第三换热器81的第二流道81b中与第一流道81a中的冷媒换热后,部分直接流回第一散热器82与车辆的电机电控进行热交换,另外部分流向第二散热器83,冷却液在第二散热器83进行热交换后,流回第一散热器82与车辆的电机电控进行热交换。
冷媒循环回路101有吸热需求,同时高压热管理子系统1001有散热需求,且冷媒循环回路101的吸热需求高于高压热管理子系统1001的散热需求时,高压热管理子系统1001可按混合工况运行。
从第一散热器82流出的高温冷却液流入第二流道81b,与流经第一流道81a的低温冷媒进行热交换,将车辆的电机电控产生的热量传递到冷媒循环回路101,经过热交换的冷却液部分流回第一散热器82,另外与部分冷却液即流向第二散热器83,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1001具有第一工况、第二工况、第三工况和混合工况,其中第三工况循环回流中的冷却剂不会与冷媒循环回路101中的冷媒进行热交换,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冷媒循环回路101中的冷媒加热。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1001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1001的第一工况、第二工况和混合工况相互配合。
实施例十七为仅有乘员舱采暖的工况,如图23所示,此时冷媒按实施例一的工况运行,冷却液按第一工况运行。

下面简单描述实施例二十九中冷媒的循环路径。从压缩机11的排气口流出高温高压的气态冷媒,并经由第三排气流道10c流向车外冷凝器130,冷媒在车外冷凝器130处液化放热,随后冷媒经过第一电子膨胀阀31和第二电子膨胀阀32节流降压后流向第一换热板21和第二换热板22,冷媒在第一换热板21和第二换热板22处吸热汽化,并经过第一节流元件41和第二节流元件42的节流降压后,最终变为低温低压的气态冷媒从压缩机11的进气口流入,从而实现第一换热板21和第二换热板22对电池模组制冷。

在由压缩机11、换热组件2和第二换热器13共同形成的冷媒回路中,从压缩机11的排气口流出的高温高压的气态冷媒在第二换热器13处进行热交换,冷媒放热液化,随后冷媒经过节流降压后经过换热组件2,在换热组件2处吸热汽化,最终变为低温低压的气态冷媒从压缩机11的进气口流入。冷媒在换热组件2处吸热,与电池模组进行热交换,从而实现对电池模组的制冷,以便于使得电池模组具有合适的工作温度,从而保证电池模组工作稳定、可靠。比如,在夏天环境温度过高,或者电池模组工作温度较高时,可对电池模组进行降温,提升电池模组工作安全性,延长电池模组的工作稳定性。
根据本申请实施例的热管理系统100,通过设置第一换热和第二换热板22对电池模组进行热交换,可对电池模组的不同端面直接接触热交换,不但可降低布置难度,并且可提升换热效率,使电池模组快速达到合适的工作温度,提升电池模组的工作稳定性,提升热管理系统100的工作效率。

在一些实施例中,第一换热板21和第二换热板22设于电池模组上且与电池模组热交换。
在本申请的一些实施例中,第一换热板21和第二换热板22设于电池模组的相对侧壁,以便于减小电池模组的温度差异,提升电池模组的循环使用寿命。
例如,电池模组可以包括至少一排电池组,电池组包括至少一个电池单体;当电池组包括多个电池单体时,多个电池单体可以沿第一换热板213的长度方向依次布置。可选地,电池单体具有多个侧壁,多个侧壁包括相对的换热侧壁,换热侧壁的面积大于其余侧壁的面积,第一换热板21和第二换热板22分别与换热侧壁导热配合;但不限于此。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例 或示例中。在本说明书中,对上述术语的示意性表述不一定指的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
