技术领域
本申请涉及储能装置技术领域，特别是涉及一种用于储能装置的热管理系统和储能装置。
背景技术
为了便于储能装置的移动与运输，在相关技术中出现了一种集装箱式储能装置，在集装箱式储能装置内设置有多个电池柜，每个电池柜内设有用于储能的电池包。而电池包在充放电过程中会产生大量的热量，为了给这些电池包降温，在该种集装箱式储能装置中配备了相应的散热装置。
传统的散热装置包括主管路和连接于主管路的多个分支管路，为了优化管路布局，通常需要设置偶数个分支管路，导致该散热装置存在极大的应用局限性。
发明内容
基于此，有必要针对现有散热装置存在极大的应用局限性的问题，提供一种用于储能装置的热管理系统和储能装置。
根据本申请的一个方面，提供了一种用于储能装置的热管理系统，储能装置包括多个电池柜，电池柜内设有电池包，热管理系统包括冷水机组以及多组第一管路组件。多组第一管路组件与多个电池柜一一对应，且多组第一管路组件并联连接于冷水机组。每一第一管路组件包括两个电池柜管路，该两个电池柜管路的一端分别连接于冷水机组的进水侧和出水侧，两个电池柜管路的另一端均分别穿入对应的电池柜，并连接于该电池柜内的电池包的水冷板。
本申请的技术方案中，从冷水机组的出水侧流出的水，可分别流入多组第一管路组件的其中一个电池柜管路中，再流入对应的电池柜内的电池包的水冷板中，流入电池包的水冷板的水可与电池包内的空气进行换热，经过换热后的水再流入对应的第一管路组件的另一个电池柜管路中，多组第一管路组件的电池柜出管内的水均可回流至冷水机组的进水侧，如此，可利用冷水机组分别对多个电池柜内的电池包进行热管理，且多个第一管路组件两两相互独立，可对每一第一管路组件进行独立控制，显然，该热管理系统摒弃了主管路的设计，第一 管路组件的数量不受限制，且多组第一管路组件的并联节点不再受限于主管路，可拓宽该热管理系统的应用范围。
在其中一个实施例中，电池柜管路远离冷水机组的一端被配置为从对应电池柜的底端穿入，以与该电池柜内的电池包的水冷板连接。避免因管路从电池柜顶端穿入电池柜内而出现管路内泄漏的液体流到电池柜内电池包处的情况，可减少安全隐患。
在其中一个实施例中，电池柜管路包括连接于水冷板的第一管路、连接于冷水机组的第二管路，以及连接第一管路和第二管路且穿过对应电池柜的底端的管接头。管接头上套设有密接于对应电池柜的底端的法兰。可在不影响管接头穿过对应电池柜的底端的情况下，提高电池柜的密封性。
在其中一个实施例中，法兰朝向对应电池柜底端的一侧设有密接于对应电池柜的底内壁的密封圈，以使法兰密接于对应电池柜的底端。可将法兰压设固定于对应电池柜的底内壁，既可稳定地安装该法兰，也可使密封圈被压紧地贴合于对应电池柜的底内壁，提高电池柜的密封性，确保电池柜内的环境不受外界大气环境湿度、温度的影响。
在其中一个实施例中，第二管路还包括连接于管接头且垂直于电池柜的底面的第一段，以及连接于冷水机组且平行于电池柜的底面的第二段。既方便第一段连接于穿过对应电池柜底端的管接头，又能使第二段沿着平行于电池柜的底面的方向排布，有利于节省第一管路组件的占用空间。
在其中一个实施例中，第一段上设有排液口，排液口上设有常闭的截止阀，第二段与冷水机组之间设有通断阀。可以在需要的时候关闭通断阀并打开该截止阀，以排空电池柜管路内的流体，方便对电池柜管路进行排查和检修。
在其中一个实施例中，电池柜内设有多个电池包，第一管路上设有一一对应地相连于多个电池包的水冷板的多个支管。每一组第一管路组件与冷水机组构成一个电池柜循环回路，一个电池柜循环回路内的流体可分别供给至对应电池柜内多个电池包的水冷板，以对多个电池包进行热管理。
在其中一个实施例中，电池柜管路上均设有保温层。可提高电池柜管路的保温效果，避免电池柜管路上出现凝露冷凝的现象。
在其中一个实施例中，多个电池柜分为沿第一方向间隔设置的两组电池柜组，每组电池柜组包括沿第二方向间隔设置的多个电池柜。多组第一管路组件沿第一方向间隔排布。第一方向与第二方向彼此垂直。可使热管理系统的管路布局更合理，更有利于减少第一管路组件的占用空间。
在其中一个实施例中，储能装置还包括电气仓，热管理系统还包括设置于电气仓内的换热器，以及分别连接于换热器和冷水机组的第二管路组件。冷水机组与换热器的换热管连接形成电气仓循环管路，电气仓循环管路内的流体可与换热器所处环境内的空气进行换热， 即电气仓循环管路内的流体可与电气仓内的空气进行换热，以使电气仓内的温度调节至合适的温度。
在其中一个实施例中，电气仓内设有配电箱，热管理系统包括分别设置于配电箱的进风口和出风口的两个换热器，进风口和出风口上均设有朝向相邻的换热器的散热风扇。可利用两组散热器组件，提高配电箱内外空气的流通，提高换热效果，一定程度上也提高了冷水机组的能效，降低了储能装置内电池包和电器件的整体运营能耗。
根据本申请的另一个方面，提供了一种储能装置，包括上述的用于储能装置的热管理系统。

在本申请实施例的描述中，技术术语“第一”“第二”等仅用于区别不同对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量、特定顺序或主次关系。在本申请实施例的描述中，“多个”的含义是两个以上，除非另有明确具体的限定。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本申请实施例的描述中，术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在本申请实施例的描述中，术语“多个”指的是两个以上(包括两个)，同理，“多组”指的是两组以上(包括两组)，“多片”指的是两片以上(包括两片)。
在本申请实施例的描述中，技术术语“中心”“纵向”“横向”“长度”“宽度”“厚度”“上”“下”“前”“后”“左”“右”“竖直”“水平”“顶”“底”“内”“外”“顺时针”“逆时针”“轴向”“径向”“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。

为了便于储能装置的移动与运输，在相关技术中出现了一种储能装置式储能装置，在储能装置的箱体内设置有多个电池柜，每个电池柜内设有用于储能的电池包。而电池包在充放电过程中会产生大量的热量，为了给这些电池包降温，在现有的储能装置式储能装置中配备了相应的散热装置。
现有的散热装置包括主管路和连接于主管路的多个分支管路，多个分支管路一一对应地给多个电池柜内的电池包降温，为了优化管路布局，通常需要设置偶数个分支管路，以保持主管路分流的平衡性，如此，极大地限制了散热装置的应用。另外，多个分支管路的并联节点设置在主管路的中间，导致主管路的分流点灵活性不高，也会限制散热装置的应用。
为了解决现有散热装置存在极大的应用局限性的问题，申请人经过研究发现，需要设 计出一种热管理系统，将多个第一管路组件并联于冷水机组，每一第一管路组件都是独立的管路，可以给对应的电池柜进行冷却液输送。多个第一管路组件彼此独立，可单独控制用于给电池柜降温的管路组件，且摒弃了主管路的设计，第一管路组件的数量不受限制，且多个第一管路组件的并联节点不再受限于主管路。
本申请实施例公开的热管理系统可以但不限用于储能装置中。可以使用本申请公开的热管理系统对储能装置内的电源系统进行热管理，这样，有利于电源系统保持长效稳定地使用，以提高电源系统的使用寿命和安全性。
图1示出了本申请一实施例中的储能装置10的结构示意图。
参阅图1，本申请一实施例提供的储能装置10，包括多个电池柜110，以及热管理系统。电池柜110内设有电池包，热管理系统用于对电池柜110内的电池包进行热管理。
图2示出了本申请一实施例中的热管理系统的管路示意图。
根据本申请的一些实施例，参阅图2，本申请一实施例提供的用于储能装置10的热管理系统，包括冷水机组210以及多组第一管路组件。多组第一管路组件与多个电池柜110一一对应，且多组第一管路组件并联连接于冷水机组210。
第一管路组件的数量与电池柜110的数量相对应，且第一管路组件内的流体供给至对应的电池柜110内的电池包的水冷板120，以对对应的电池柜110内的电池包进行热管理。
每一第一管路组件包括两个电池柜管路220，该两个电池柜管路220的一端分别连接于冷水机组210的进水侧和出水侧，该两个电池柜管路220的另一端分别穿入对应的电池柜110，并连接于该电池柜110内的电池包的水冷板120。
为了方便说明，两个电池柜管路220分别为连接于冷水机组210的出水侧的电池柜进管221，以及连接于冷水机组210的进水侧的电池柜出管222。那么，电池柜进管221和电池柜出管222远离冷水机组210的一端均连接于对应的同一电池柜110内的电池包的水冷板120。
冷水机组210的出水侧流出的流体的温度可根据电池包需要的温度进行调节，可在电池包处设置第一温度传感器，第一温度传感器和冷水机组210均电连接于控制器，控制器根据第一温度传感器获取的温度使冷水机组210流出适宜温度的流体。
流体可以为水等换热媒介。
可以理解，从冷水机组210的出水侧流出的水，可分别流入多组第一管路组件的电池柜进管221中，再流入对应的电池柜110内的电池包的水冷板120中，流入电池包的水冷板120的水可与电池包内的空气进行换热，经过换热后的水再流入对应的电池柜出管222中，多组第一管路组件的电池柜出管222内的水均可回流至冷水机组210的进水侧，如此，可利用冷水机组210分别对多个电池柜110内的电池包进行热管理，且多个第一管路组件两两相互独立，可对每一第一管路组件进行独立控制，显然，该热管理系统摒弃了主管路的设计， 第一管路组件的数量不受限制，且多组第一管路组件的并联节点不再受限于主管路，可拓宽该热管理系统的应用范围。
需要说明的是：流入电池包的水冷板120的水可与电池包内的空气进行换热，包括两种情况，第一种情况是：流入电池包的水冷板120的水可在电池包温度较高时带走该电池包的热量。第二种情况是：流入电池包的水冷板120的水可在电池包温度较低时给电池包提供热量。
根据本申请的一些实施例，电池柜管路220远离冷水机组210的一端被配置为从对应电池柜110的底端穿入，以与该电池柜110内的电池包的水冷板120连接。
也就是说，电池柜进管221和电池柜出管222远离冷水机组210的一端分别穿入对应电池柜110的底端，并与该电池柜110内的电池包的水冷板120连接。
电池柜进管221和电池柜出管222远离冷水机组210的一端均从对应的电池柜110的底端穿入对应的电池柜110，避免因管路从电池柜110顶端穿入电池柜110内而出现管路内泄漏的液体流到电池柜110内电池包处的情况，可减少安全隐患。
根据本申请的一些实施例，请参阅图2，并结合参阅图3和图4，电池柜管路220包括连接于水冷板120的第一管路223、连接于冷水机组210的第二管路224，以及连接第一管路223和第二管路224且穿过对应电池柜110的底端的管接头2251，管接头2251上套设有密接于对应电池柜110的底端的法兰2252。
可以理解，第一管路223位于对应电池柜110内，第二管路224位于对应电池柜110外。管接头2251穿过对应电池柜110，那么，电池柜110上设有供管接头2251穿过的开口。
密接于对应电池柜110底端的法兰2252，可在不影响管接头2251穿过对应电池柜110的底端的情况下，提高电池柜110的密封性。
在一些实施例中，请参阅图2，两个电池柜管路220共用一个法兰2252，也就是说，电池柜进管221和电池柜出管222共用一个法兰2252。
在一些实施例中，请参阅图4，两个电池柜管路220的管接头2251均贯穿于该法兰2252，且管接头2251与法兰2252一体成型，管接头2251与法兰2252组合形成法兰组件225，更方便使用。
根据本申请的一些实施例，请参阅图2，法兰2252朝向对应电池柜110底端的一侧设有密接于对应电池柜110的底内壁的密封圈2253，以使法兰2252密接于对应电池柜110的底端。
可以理解，法兰2252位于电池柜110。
可将法兰2252压设固定于对应电池柜110的底内壁，既可稳定地安装该法兰2252，也可使密封圈2253被压紧地贴合于对应电池柜110的底内壁，提高电池柜110的密封性，确保电池柜110内的环境不受外界大气环境湿度、温度的影响。
也就是说，电池柜管路220可穿过对应电池柜110上的开口，同时，也可利用法兰2252上的密封圈2253提高电池柜110的密封性，不会因开口的设置而影响电池柜110的密封性。
根据本申请的一些实施例，请参阅图2，并结合参阅图5及图6，第二管路224还包括连接于管接头2251且垂直于电池柜110的底面的第一段a，以及连接于冷水机组210且平行于电池柜110的底面的第二段b。
可见，第二管路224呈L型结构。
既方便第一段a连接于穿过对应电池柜110底端的管接头2251，又能使第二段b沿着平行于电池柜110的底面的方向排布，有利于节省第一管路组件的占用空间。
在一些实施例中，请参阅图3及图6，第二段b平行于电池柜110的底板的宽度方向，多组第一管路组件的第二段b沿电池柜110的底板的长度方向间隔排布，布局合理，更有利于第一管路组件的占用空间。
在一些实施例中，请参阅图5及图6，第二管路224包括连接于管接头2251的L型管2241和连接于L型管2241的长管2242，第一段a形成于L型管2241远离长管2242的一段，第二段b形成于长管2242。使平行于电池柜110的底面的方向排布的第二段b借助于L型管2241能够更好地与管接头2251相连。
在一些实施例中，L型管2241可以为尼龙管，尼龙管上设有保温层，可提高L型管2241的绝缘效果和保温效果。
长管2242可以为铝管，重量更轻，强度更好。
根据本申请的一些实施例，请参阅图5，并结合参阅图7，第一段a上设有排液口，排液口上设有常闭的截止阀c。第二段b与冷水机组210之间设有通断阀2261。
该截止阀c处于常闭状态，第一段a不会因该排液口而出现泄露。确保正常运营的第一管路组件是一个密闭系统，有利于维持第一管路组件内部流体的洁净、稳定和长效，可以解决工程上频繁更换和添加防冻液的问题，降低了系统运营维护成本。
可以在需要的时候关闭通断阀2261并打开该截止阀c，以排空电池柜管路220内的流体，方便对电池柜管路220进行排查和检修。
需要说明的是，因多组第一管路组件彼此独立，在某一第一管路组件的电池柜管路220需要进行排查和检修时，可单独进行对应的排查和检修，不影响其他第一管路组件的使用，可见，该热管理系统的设计可提高检修的便利性。
在一些实施例中，请参阅图2，并结合参阅图8，第一管路223远离管接头2251的一端设有排气阀2232，可在完成电池柜管路220的排查和检修后，采用注液工装向排液口内注入与冷水机组210流出的流体相同的流体，并打开排气阀2232，方便电池柜管路220内空气的排空。
需要说明的是，图8示出了两个电池柜管路220的第一管路223的结构示意图。
在一些实施例中，通断阀2261可以为球阀，方便控制冷水机组210供给至对应电池柜110内电池包的冷水板内的流体的通断，可以实现分别给各组第一管路组件加注防冻液，有利于降低运维难度和成本。
在一些实施例中，请参阅图2及图7，第二段b与冷水机组210之间设有尼龙管路226，球阀设置于尼龙管路226，方便调控电池柜管路220的通断。

可以理解，每一组第一管路组件与冷水机组210构成一个电池柜循环回路，一个电池柜循环回路内的流体可分别供给至对应电池柜110内多个电池包的水冷板120，以对多个电池包进行热管理。
根据本申请的一些实施例，电池柜管路220上均设有保温层，可提高电池柜管路220的保温效果，避免电池柜管路220上出现凝露冷凝的现象。
L型管2241和第一管路223均可以为尼龙管，尼龙管上设有保温层，具体地，尼龙管由多层高分子材料形成，且尼龙管上还设有保温棉层，可有效避免尼龙管上出现凝露冷凝的现象。

如此，冷水机组210与换热器231的换热管连接形成电气仓循环管路，电气仓循环管路内的流体可与换热器231所处环境内的空气进行换热，即电气仓循环管路内的流体可与电气仓130内的空气进行换热，以使电气仓130内的温度调节至合适的温度。
在一些实施例中，请参阅图2，换热器231和第二管路组件240之间设有水泵250，水泵250可通过螺栓锁附在电气仓130内，借助于水泵250可将冷水机组210内的流体(如 冷却液)压送至换热器231的换热管内，以实现电气仓循环管路内的流体可与电气仓130内的空气进行换热。
在一些实施例中，第二管路组件240可由扎带组件固定于电气仓130内，提高第二管路组件240的稳定性。
在一些实施例中，可根据电气仓130内配电箱所需的温度调节电气仓130内的温度，具体地，可在配电箱内设置电性连接于控制器的第二温度传感器，控制器根据第二温度传感器获取的温度使冷水机组210流出合适温度的流体，以使电气仓130内的温度调节至合适的温度。
根据本申请的一些实施例，电气仓130内设有配电箱。热管理系统包括分别设置于配电箱的进风口和出风口的两个换热器231，进风口和出风口上均设有朝向相邻的换热器231的散热风扇232。
一个换热器231和与之相邻的散热风扇232可组合形成散热器组件230。
可利用两组散热器组件230，提高配电箱内外空气(配电箱外空气即为电气仓130内空气)的流通，提高换热效果，一定程度上也提高了冷水机组210的能效，降低了储能装置10内电池包和电器件的整体运营能耗。
根据本申请的一些实施例，参阅图2，每一组第一管路组件与冷水机组210构成一个电池柜循环回路，一个电池柜循环回路内的流体可分别供给至对应电池柜110内多个电池包的水冷板120，以对多个电池包进行热管理。每一第一管路组件包括连接于冷水机组210的出水侧的电池柜进管221，以及连接于冷水机组210的进水侧的电池柜出管222。电池柜进管221和电池柜出管222均包括第一管路223、L型管2241、长管2242和尼龙管路226，其中，第一管路223、L型管2241和尼龙管路226上均设有保温棉层，长管2242为铝管。电池柜进管221和电池柜出管222共用一个法兰组件225，一方面，可使电池柜进管221和电池柜出管222远离冷水机组210的一端均从对应的电池柜110的底端穿入对应电池柜110，可减少安全隐患；另一方面，可利用法兰组件225提高电池柜110的密封性，确保电池柜110内的环境不受外界大气环境湿度、温度的影响。
在一些实施例中，长管2242大致平行于电池柜110的底板的宽度方向，多组电池柜管路220的长管2242沿电池柜110的底板的长度方向间隔排布，布局合理，更有利于第一管路组件的占用空间。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在 不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
