下面参考附图描述根据本公开实施例的热管理***1。
如图1-图4所示,根据本公开实施例的热管理***1包括发动机冷却器100、废气再循环***冷却器200和调温散热组件300。
发动机冷却器100具有进液口110和出液口120,废气再循环***冷却器200的出口201与进液口110连通,且废气再循环***冷却器200的进口202与出液口120连通,即废气再循环***冷却器200与发动机冷却器100串联。调温散热组件300的进口301与废气再循环***冷却器200的进口202连通,调温散热组件300的出口302与废气再循环***冷却器200的出口201连通,即调温散热组件300与废气再循环***冷却器200串联。
其中,由发动机冷却器100的出液口120流出的一部分冷却液可以流向调温散热组件300,再通过进液口110流回发动机冷却器100,而另一部分冷却液可以流向废气再循环***冷却器200,换热后再流回发动机冷却器100。其中,发动机冷却器100可以与发动机进行热交换,从而实现发动机的快速降温,即在发动机温度过高时能够快速为发动机降温,保证发动机的正常运行。
根据本公开实施例的热管理***1,通过将废气再循环***冷却器200的出口201与进液口110连通,且废气再循环***冷却器200的进口与出液口120连通,废气再循环***冷却器200与发动机冷却器100串联,这样,发动机冷却器100和废气再循环冷却器200连接在同一条管路内,发动机冷却器100内的冷却液可以直接流入废气再循环冷却器200,也就是说,无需额外增设电子水泵提供冷却液的驱动力给废气再循环***冷却器200。由此,既可以满足发动机冷却器100的冷却需求和废气再循环***冷却器200的冷却需求,又可以减小冷却液的整体流量,从而减小电子水泵的流量,进而可以降低电子水泵的功耗,以及降低发动机的油耗。
另外,调温散热组件300与废气再循环***冷却器200串联,由此,由发动机冷却器100流出的冷却液既可以流经废气再循环***,也可以流经调温散热组件300,也就是说,发动机冷却器100流出的冷却液有两条流动路径。这样,在暖机过程中,调温散热组件300可以关闭,此时经由发动机冷却器100流出的冷却液不经过调温散热组件300,同时可以通过降低电子水泵的转速,使进入发动机冷却器100的冷却液较少,并且流经废气再循环***冷却器200的冷却液可以吸收废气再循环***的热量用于发动机的暖机,从而使发动机快速暖机,极大地提高了发动机的暖机效率,进一步降低发动机的油耗,且可以减少有害气体的排放。
由此,根据本公开实施例的热管理***1,具有能耗低、发动机油耗低和暖机速率快等优
点。
在本公开的一些实施例中,如图1-图4所示,调温散热组件300包括串联的调温器320和散热器310,即调温器的出口322与散热器310的进口312连通,调温器320的进口与废气再循环冷却器200的进口202连通,散热器310的出口与废气再循环冷却器200的出口201连通。也就是说,调温器320和散热器310在同一条管路上,而废气再循环***冷却器200在另一条管路上,经由发动机冷却器100的出液口120流出的一部分冷却液可以流向调温器320和散热器310,再通过进液口110流回发动机冷却器100,而另一部分冷却液可以流向废气再循环***冷却器200,换热后再流回发动机冷却器100。也就是说,发动机冷却器100流出的冷却液有两条流动路径。这样,在暖机过程中,调温器300可以关闭,此时经由发动机冷却器100流出的冷却液不经过散热器310,同时可以通过降低电子水泵的转速,使进入发动机冷却器100的冷却液较少,并且流经废气再循环***冷却器200的冷却液可以吸收废气再循环***的热量用于发动机的暖机,从而使发动机快速暖机。
在本公开的一些具体实施例中,如图1-图4所示,热管理***1还包括暖风模块400,暖风模块400的出口401与进液口110连通,且暖风模块400的入口402与出液口120连通,即暖风模块400与发动机冷却器100串联。由此,暖风模块400和发动机冷却器100可以组成一个循环,发动机冷却器100内的冷却液流经暖风模块400可以对车舱内进行加热,从而可以利用发动机的热量对车舱内进行加热,提高了发动机热量的利用率,能够减小能耗。
在本公开的一些具体实施例中,如图1-图4所示,暖风模块400与废气再循环***冷却器200并联;或者,暖风模块400与废气再循环***冷却器200串联。这样,暖风模块400和废气再循环***冷却器200的连接更加简单。也就是说,经由发动机冷却器100流出的一部分冷却液可以流向废气再循环***冷却器200,而另一部分冷却液可以流向暖风模块400,这样流经暖风模块400的冷却液、流经废气再循环***冷却器200的冷却液和经过发动机冷却器100共用的冷却液以及散热装置,无需额外增设电子水泵提供冷却液的驱动力给废气再循环***冷却器200,在保证废气再循环***冷却器200的冷却需求的前提下减小了电子水泵的流量以及零件数量,这样也可以在一定程度上减少电子水泵的功耗,从而降低发动机油耗,也简化了车辆结构,降低成本。
在本公开的一些具体实施例中,如图1-图4所示,热管理***1还包括电池冷却***500、第一换热板600和三通阀700。
第一换热板600具有第一换热通道610和第二换热通道620,第一换热通道610接入电池冷却***500,第二换热通道620的第一端621与进液口110连通。三通阀700包括第一开口710、第二开口720和第三开口730,第一开口710与进液口110连通,第二开口720与第二换热通道620的第二端622连通,第三开口730与暖风模块400连通。第三开口730可选择地与第一开口710和第二开口720中的其中一个连通。
也就是说,发动机冷却器100内的冷却液可以流经第二换热通道620,电池冷却***500
内的冷却液可以流经第一换热通道610,这样,发动机冷却器100内的冷却液和电池冷却***500中的冷却可以在第一换热板600内进行热交换,从而利用发动机冷却器100为电池冷却***500进行加热,进一步提高电池冷却***500的升温速率,为电池的效率提供保障。这样给电池包510进行加热时,不需要额外的能量,既提升了电池包510的效率,又不需额外的功耗,提高了能量的利用率。
其中,第二开口720与第一开口710连通时,发动机冷却器100和第一换热板600断开连通,也就是说,第一换热板600不参与发动机冷却器100内的冷却液的回路,发动机冷却器100和电池冷却***500不进行换热,第一换热板600相当于管路;而当第二开口720和第三开口730连通时,发动机冷却器100和电池冷却***500通过第一换热板600进行热交换,发动机冷却器100可以为电池冷却***500加热。
在本公开的一些具体实施例中,如图1-图4所示,第三开口730通过废气再循环***冷却器200与暖风模块400连通。
这样,当电池包510需要加热时,冷却液流经第二换热通道620之前会与废气再循环***冷却器200换热,以吸收废气再循环***的热量,从而冷却液流经第二换热通道620的温度更高,可以快速提升进入第一换热板600的第二换热通道620的冷却液的温度,尤其是,在低温环境启动时,可以快速为电池冷却***500提供热量,使电池包510快速达到合适温度,为电池的效率提供保障,并且,将废气再循环***冷却器200与暖风模块400串联后,不需要为废气再循环***冷却器200额外增加电子水泵,也不需要电子水泵额外增加流量,也就是说废气再循环***冷却器200和发动机冷却器100可以共用同一个水泵,在一定程度上能够减少电子水泵的功耗,从而降低发动机油耗。
在本公开的一些具体实施例中,如图1-图4所示,热管理***1还包括空调***800和第二换热板900。
第二换热板900具有第三换热通道910和第四换热通道920,第三换热通道910接入电池冷却***500,第四换热通道920接入空调***800。
也就是说,电池冷却***500内的冷却液可以流经第三换热通道910,空调***800内的冷媒可以流经第四换热通道920,第三换热通道910内的冷却液可以和第四换热通道920内的冷媒进行热交换。这样,当环境温度较低时,可以利用空调***800内的冷媒为电池冷却***500内的冷却液进行加热,从而提高电池冷却***500内的冷却液的温度,并通过电池冷却***500内的冷却液为电池包510进行加热,保证电池包510处于舒适的工作温度区间;当环境温度较高时,可以利用空调***800内的冷媒为电池冷却***500内的冷却液进行降温,从而降低电池冷却***500内的冷却液的温度,并通过电池冷却***500内的冷却液为电池包510进行降温,保持电池包510能够处于正常工作状态。
并且,通过设置第一换热板600和第二换热板900,发动机冷却器100和空调***800可以同时与电池冷却***500进行热交换,这样进一步提高了电池冷却***500的升温速率速
率,实现电池包510的快速升温,从而给电池包510进行加热时,不需要额外的能量,既提升了电池包510的效率,又不需额外的功耗。当然,可以理解的是,在电池包510需要加热时,可以只利用发动机冷却器100与电池冷却***500换热,且空调***800不与电池冷却***500换热,或者,可以只利用空调***800与电池冷却***500换热,且发动机冷却器100不与电池冷却***500换热。
在本公开的一些具体实施例中,如图1-图4所示,空调***800包括压缩机810、第一换热器820和第二换热器830。
第一换热器820的第一端821与压缩机810连接,第二换热器830的第一端831通过通断阀840与第一换热器820的第二端822连接,第二换热器830的第二端832与压缩机810连接。其中,第四换热通道920的两端分别与压缩机810和第一换热器820的第二端822连接。其中,第一换热器820和第二换热器830之间设有膨胀阀,膨胀阀可以为热力膨胀阀,膨胀阀可以位于通断阀840和第二换热器830之间。
举例而言,第一换热器820可以作为空调***800的冷凝器进行制热,第二换热器830可以作为空调***800的蒸发器进行制冷。并且,BMS(BATTERY MANAGEMENT SYSTEM,电池管理***)根据电池包510内温度传感器信号,然后向MCU(Micro Control Unit,微控制单元)发出冷却、加热、均衡请求信号,MCU根据BMS的请求信号及空调***800的温度压力传感器,根据实验及仿真参数设定各个部分的温度目标及限值对压缩机810、下文所述的电子膨胀阀850和电子水泵进行控制,以实现各个工况下的最佳温度及能耗目标。
其中,在空调***800制冷时,从第一换热器820流出的冷却液中的一部分流经第四换热通道920,并与第三换热通道910内的冷却液进行换热,从而对电池冷却***500进行降温,另一部分流经通断阀840和第二换热器830,从而压缩机810、第一换热器820、通断阀840和第二换热器830组成冷媒回路,第一换热器820为冷凝器,第二换热器830为蒸发器,用于对车舱内制冷。
在本公开的一些具体实施例中,如图1-图4所示,第四换热通道920和第一换热器820之间设有电子膨胀阀850。这样,电子膨胀阀850可以控制第四换热通道920与空调***800之间的通断,从而在电池包510的温度正常时,既电池包510既不需要加热也不需要制冷时,空调***800的冷却液和电池冷却***500不进行换热。
其中,在空调***800对电池冷却***500进行辅助冷却时,电子膨胀阀850接通,低温低压的气体经压缩机810后变为高温高压气体,高温高压气体经过第一换热器820后变为高压低温液体,一部分高压低温液体进入第二换热器830,从而压缩机810、第一换热器820和第二换热器830组成冷媒回路,用于对车舱内制冷,另一部分高压低温液体则通过电子膨胀阀850进入第四换热通道920与电池冷却***500进行热交换,然后变成低压低温气体进入压缩机810,完成循环。此时第一换热器820为冷凝器,第二换热器830为蒸发器。
在本公开的一些具体实施例中,如图1-图6所示,发动机冷却器100包括缸盖水套140、
缸体水套130和连接水套150。
缸盖水套140用于冷却发动机的缸盖,且缸盖水套140设有出液口120,缸体水套130用于冷却发动机的缸体,缸体水套13的出口133与出液口120连通,缸体水套130的进口134与缸盖水套140的进口141连通,发动机的各个部位的被冷却效果都较好,冷却更加全面。连接水套150设有进液口110,进液口110分别与缸盖水套140的进口141和缸体水套130的进口133连通。也就是说,缸盖水套140和缸体水套130并联且与连接水套150串联。
需要说明的是,缸体水套130和缸盖水套140并联,且缸体水套130和缸盖水套140与连接水套150串联,是指缸体水套130和缸盖水套140并联后两者整体和连接水套150连通,经过连接水套150流出的冷却液可以分别流向缸体水套130和缸盖水套140,然后缸体水套130和缸盖水套140流出的冷却液可以汇集到一起,再分成三路,一路流向膨胀水壶,带走发动机冷却器100***中产生的气体,然后通过膨胀水壶给发动机冷却器100内的电机水泵补水,维持发动机冷却器100的冷却液的流动压力,防止沸腾或者电子水泵气蚀;一路经暖风模块400后进入废气再循环***冷却器200,若电池冷却***500有加热需求,三通阀700的第三开口730与第二开口720连通,暖风模块400的冷却液流入第一换热板600并与电池冷却***500换热,再流回发动机冷却器100,若电池冷却***500无加热需求,则三通阀700的第三开口730与第一开口710连通,暖风模块400的冷却液直接流回发动机冷却器100;一路进入调温器300,调温器300打开则冷却液进入散热器310散热后流回发动机冷却器100完成循环,若调温器300未打开则散热器310不参与循环。
此外,通过调整连接水套150与缸体水套130的连通口的大小,以及连接水套150与缸盖水套140的连通口的大小,可以合理分配连接水套150流向缸体水套130的流量和缸盖水套140的流量,能够实现在低温环境启动时减少发动机的暖机时间,从而降低油耗及有害气体的排放。例如,连接水套150与缸体水套130的连通口增大,则冷却液进入缸体水套130的流量就会增大,冷却液进入缸盖水套140的流量就会减小,这样,可以调节发动机冷却器100对发动机的缸体和缸盖的冷却速率。
在本公开的一些具体实施例中,如图1-图6所示,热管理***1还包括增压器冷却器160。
缸体水套130具有相对的进气侧水套131和出气侧水套132,进气侧水套131与连接水套150连接,出气侧水套132与增压器冷却器160连通,进气侧水套131和出气侧水套132分别与出液口120连通。这样,出水侧水套132流出的冷却液可以流入增压器冷却器160,增压器冷却器160可以为增压器进行冷却,避免增压器的温度过高,以使增压器能够正常工作。
如图7所示,根据本公开第二方面实施例的车辆2,车辆2包括根据本公开上述第一方面实施例的热管理***1。
根据本公开实施例的车辆2,通过采用上述热管理***1,具有能耗低、发动机油耗低和暖机速率快等优点。
根据本公开实施例的热管理***1和具有其的车辆2的其他构成以及操作对于本领域普通
技术人员而言都是已知的,这里不再详细描述。
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公开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。
尽管已经示出和描述了本公开的实施例,本领域的普通技术人员可以理解:在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型,本公开的范围由权利要求及其等同物限定。
