Abstract

公开一种一体式电池化成设备，其包括化成模块、电源模块、热媒管道和冷媒管道。本申请一体式电池化成设备能够降低温控成本以及能耗，同时减小电源箱的温控对环境温度的影响。

Description

一种一体式电池化成设备
本申请要求于2022年12月02日提交中国专利局、申请号为202223236315.5、发明名称为“一种一体式电池化成设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及化成设备领域，特别是一种一体式电池化成设备。
背景技术
环境温度对锂电池的化成效果具有重要的影响，为此，现有的锂电池化成工序会在高温的温控车间内进行，从而准确控制环境温度。搭建高温的温控车间需要较大的成本，同时运行能耗巨大。
为了解决这一问题，现有技术中出现了专门的化成设备，化成设备将化成治具置于密闭的化成室内，因此只需要保证化成室处于高温即可，化成设备可以在常温的车间中使用。但是，目前通常使用电加热管加热化成室内的空气实现温控效果，电加热管成本较高，并且由于化成时间较长，电加热管需要持续运行，使用寿命较短。
现有技术中，化成设备的电源箱一般靠自带的散热风机进行温控，一方面，车间中通常会密集摆放多个化成设备，电源箱产生的热量散发至车间的环境中，会使得环境温度升高，降低车间的环境舒适度，影响工作人员的健康，车间内的温度波动也可能对化成室产生干扰，另一方面，由于化成设备在运行时电流较大，电源箱发热严重，仅凭自带的散热风机难以满足电源箱的散热需求，电源箱容易出现故障。
因此，现有技术中化成设备的温控成本较高、能耗较大，温控方式有待改善。
技术问题
本申请提供一种一体式电池化成设备，能够降低温控成本以及能耗，同时减小电源箱的温控对环境温度的影响。

参照图1，本申请实施例提供的一体式电池化成设备，包括化成模块、电源模块、热媒管道和冷媒管道，化成模块包括库位和第一温控装置，库位形成用于安放锂电池的化成室，第一温控装置包括第一风机组件和第一换热器110，第一风机组件用于使气流在库位和第一换热器110之间循环流动，电源模块与化成模块相互间隔，电源模块包括电源箱310和第二温控装置，第二温控装置包括第二换热器410，第二换热器410与电源箱310传热连接，热媒管道用于接入热媒管网，热媒管道与第一换热器110传热连接，冷媒管道用于接入冷媒管网，冷媒管道与第二换热器410传热连接。
根据本申请实施例提供的一体式电池化成设备，第一风机组件使化成室的空气进入第一温控装置，空气与第一换热器110发生热交换，之后再送回化成室，从而对化成室进行控温，电源箱310与第二换热器410发生热交换，从而对电源箱310进行控温，第二换热器410与冷媒管道内的冷媒发生热交换，冷媒携带热量返回冷媒管网，首先，电源模块和化成模块相互间隔，降低了二者之间温度的相互影响，设置第二换热器410能够提高电源箱310的散热效果，提高电源箱310运行的可靠性和稳定性，其次，电源箱310产生的热量通过冷媒送出，从而降低了电源箱310的温控过程对环境温度的影响，一体式电池化成设备能够更好地对电源箱310进行温控。最后，相比于使用加热管进行化成 工序的温控，本申请通过换热方式进行温控，且温控区域局限在化成室内，多个一体式电池化成设备的化成室或者同一一体式电池化成设备的多个化成室可以共用热媒管网，因此降低了一体式电池化成设备的能耗和成本。
参照图1，可以理解的是，电源箱310是一个复杂的组件，电源箱310一般包括壳体，壳体内集成有电源、控制板、散热风扇等器件，因此电源箱310自身也具有一定的散热能力，但是在化成场景中，电源箱310自身的散热能力往往不足以满足需求，因此需要外部的第二温控装置为电源箱310进行进一步的散热。第二换热器410与电源箱310传热连接具体可以是第二换热器410的换热面与电源箱310的壳体表面相贴合，与壳体进行热交换，在另一些实施例中，也可以是壳体开设有避让孔，第二换热器410的部分位于壳体内，第二换热器410的换热面直接与电源箱310的发热部位相接触进行热交换。
第一换热器110、第二换热器410的结构属于现有技术，第一换热器110、第二换热器410内分别会布置有热媒、冷媒的换热管，将换热管分别接入冷媒管道和热媒管道即可实现换热功能。热媒、冷媒一般为液体，例如热水、冷水，基于化成的实际温度需求，热水的温度一般在60℃到70℃。
第一风机组件通过若干个风机产生循环气流，在一些实施例中，第一风机组件包括第一风机120和第二风机130，第一温控装置包括换热风道140，第一换热器110位于换热风道140内，换热风道140的入风口和出风口分别与化成室连通，第一风机120位于入风口，第二风机130位于出风口。
具体请参照图2，在一些实施例中，库位包括位于化成室内的针床210，入风口朝向针床210的侧面，出风口朝向针床210的顶部。针床210属于本领域常用的一类化成治具。首先第一风机120从侧面将化成室的空气抽入换热风道140，之后第二风机130将经过换热的热空气从顶部吹向针床。出风口从顶部吹风能够使得热空气更加均匀地吹向针床上的各个锂电池，提高锂电池温度控制的稳定性以及一致性。
当然，在另外的实施例中，也可以使入风口朝向针床210的顶部，而出风口朝向针床210的侧面。
为了进一步提高化成工序的温控效果，在一些实施例中，化成室的壁面设置有保温层。保温层能够阻碍化成室内的高温空气与外部环境的热交换，一方 面减少热量流失，另一方面能降低外部环境的温度波动对化成室的影响。从另一个角度来说，保温层也能够减小化成室与电源箱310之间的热交换，降低高温化成对电源箱310运行的影响。具体地，保温层可以为保温涂层或者保温套等。
在一些实施例中，第二温控装置包括第二风机组件，第二风机组件包括第三风机420，第三风机420设于第二换热器410的进风侧，第三风机420用于对第二换热器410风冷散热。第三风机420可以根据实际需要启停，风冷散热能够促进第二换热器410的热量释放，提高电源箱310的散热效果，避免因为散热效率不足导致电源箱310故障。需要注意的是，此时电源箱310的热量主要还是通过冷媒排往冷媒管网，第三风机420主要起到辅助散热的作用，第三风机420对环境温度的影响可以控制在可接受的范围内。
根据本申请的一些实施例，参照图3，库位包括第一接线区，第一接线区设置有第一端子，电源箱310包括第二接线区，第二接线区设置有第二端子，第一端子和第二端子相互插接或者通过线缆710电连接。首先针床210以及库位中的其它器件连接到第一端子，电源以及电源箱310中的其它器件连接到第二端子，之后再通过第一端子和第二端子之间的连接间接导通，因此无需在库位设置过线孔或者过线槽，从而提高库位的密封效果，能够保证电源箱310与库位不连通，两者不会产生气体交换，降低电源箱310与库位之间的相互影响。
现有技术中，一体式电池化成设备还存在不易维护的问题。具体来说，现有技术中的化成模块和电源模块通常会靠墙设置，因而维护人员需要站立在一体式电池化成设备的前方对针床210进行维护。以图1的实施例为例，竖直方向上设有两个库位，库位的进料口位于一体式电池化成设备的前侧，化成时，堆垛机会从前方将载有锂电池的托盘送入库位进行化成，若采用现有技术的方案，对其中一个库位进行维护时，出于安全考虑，需要将两个库位同时停机，在维护完成后再同时投入使用。
为此，在本申请的一些实施例中，参照图2，一体式电池化成设备包括过道720和电控柜730，化成模块和电源模块位于过道720的同一侧，电控柜730位于过道720的另一侧。具体参照图1，一体式电池化成设备具有机架750， 机架750形成过道720以及分别位于过道两侧的第一区、第二区，化成模块和电源模块位于第一区，电控柜730位于第二区，维护人员可以在过道上对化成模块进行维护，不会妨碍堆垛机的正常运行，因此当对一个库位进行维护时，其它库位可以正常进行化成。维护人员也可以在过道720上对电源模块以及电控柜730进行维护。此外，化成模块和电源模块位于第一区，能够便于电源箱310和针床210接线，减少线缆710的长度，从而减少损耗，降低成本。
相应地，此时进料口位于库位远离过道720的一侧。
为了便于在过道720上进行维护工作，在一些实施例中，参照图3和图4，第一接线区位于库位靠近过道720的一侧，第二接线区位于电源箱310靠近过道720的一侧。在一些实施例中，一体式电池化成设备包括线架740，线架740安装在第一接线区和第二接线区，线架740用于引导线缆710。线架740能够对各个线缆710进行导向和定位，从而方便线缆710的归纳和整理，使线缆710的布局更加清晰，便于维护。
下面参考图1、图2、图3、图4以一个具体的实施例详细描述本申请实施例的一体式电池化成设备。值得理解的是，下述描述仅是示例性说明，而不是对本申请的具体限制。本具体的实施例也可以被上述相应的技术特征替换或与上述的技术特征结合。

电源模块包括两个电源箱310和两个第二温控装置，两个电源箱310在竖直方向堆叠布置，其中一个第二温控装置布置在电源箱310的底部，另外一个第二温控装置布置在电源箱310的顶部，第二温控装置包括第二换热器410和第三风机420，第二换热器410与电源箱310传热连接，第三风机420设于第二换热器410的进风侧，第三风机420用于对第二换热器410风冷散热。
