具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
如图1至图4所示，本发明提供一种冷却组件，包括若干充电仓1，每个充电仓1内可设有若干部件。在冷却组件运行的过程中，需要对充电仓1进行降温时，位于充电仓1内的部件则都有可能被作为冷却对象2，需要对其进行降温。
充电仓1内通常会设有充电模组11、充电电池12和电池托盘13，充电模组11用于对充电电池12进行充电，电池托盘13用于托住充电电池12。在冷却组件运行的过程中，充电模组11、充电电池12充电时都会产生热量，常需要对充电模组11、充电电池12进行降温；而电池托盘13托住充电电池12，对电池托盘13进行降温，也能达到对充电电池12进行降温的效果。因此，充电模组11、充电电池12和电池托盘13都有可能作为冷却对象2，对其进行降温。
为了实现上述降温效果，该冷却组件还包括冷却单元3、主输入管4和主输出管5和若干冷却管路6，每个冷却对象2均设置有一个冷却管路6；冷却单元3具有主输出口31和主输入口32；主输入管4的一端与冷却单元3的主输出口31相连通，主输入管4的另一端与冷却管路6的入口连通；主输出管5的一端与冷却单元3的主输入口32相连通，主输出管5的另一端与冷却管路6的出口连通。
冷却剂从冷却单元3的主输出口31流出，从主输入管4分别流入各条冷却管路6中，对冷却管路6所对应的冷却对象2进行冷却。由于所有冷却管路6都共用主输入管4、主输出管5，使不同温度的冷却剂先通过混合后再流入冷却单元3，有利于热回收。在环境温度较低的情况下，经过温度较高的冷却对象2的冷却剂的温度较高，还可以用来再次流经温度较低的冷却对象2，对温度较低的冷却对象2进行加温。
当冷却对象2为充电模组11时，冷却管路6可以直接安装于充电模组11的内部和/或外表面，也可以在充电模组11的表面安装有冷却载体，冷却管路6设于冷却载体内。冷却载体可以为散热片或液冷板，散热片、液冷板的材料为石墨、铜、铝中的至少一种。图5所示为充电模组11的一种可选的冷却结构，充电模组11包括模组本体111和贴附于模组本体111的表面的散热片112，冷却管路6设置于散热片112中。当冷却剂从冷却管路6中流过时，对散热片112进行冷却，从而对模组本体111进行冷却。
如图5和图6所示，当冷却对象2为充电电池12时，冷却管路6可设置于充电电池12的内部，也可设置于充电电池12的外表面。充电仓1内还设置有充电盘7，充电盘7上设有充电接头71、冷却接头72，充电接头71用于插接在充电电池12的充电接口上，冷却接头72的一端与主输入管4和主输出管5连通，冷却接头72的另一端与冷却管路6连通。
将充电接头71、冷却接头72都集成在充电盘7上，在充电接头71与充电电池12的充电接口相连接的同时，冷却接头72也与冷却管路6相连接，充电与冷却同时启动，简化了系统控制。
如图7所示，当冷却对象2为电池托盘13，电池托盘13用于放置充电电池12，冷却管路6设置于电池托盘13内。充电仓1内还设置有快换接头，快换接头包括托盘输入接头、托盘输出接头，托盘输入接头与主输入管4相连通，托盘输入接头用于插接在冷却管路6的入口上，托盘输出接头与主输出管5相连通，托盘输出接头用于插接在冷却管路6的出口上。
设置于电池托盘13上的冷却管路6的入口、出口，伸出至电池托盘13的外部。在需要对电池托盘13进行冷却时，将快换接头插到位于电池托盘13上的冷却管路6上，即可将该冷却管路6接入冷却通道中。
当充电电池12、电池托盘13均需要进行冷却时，可以将充电盘7、快换接头集成在一起。当对充电电池12进行充电时，充电电池12、电池托盘13上的冷却管路6均接入冷却通道中。
充电模组11、充电电池12和电池托盘13可同时作为设置冷却管路6的冷却对象2，也可以选择其中一个或多个作为设置冷却管路6的冷却对象2。本实施例的冷却对象2，示例为充电模组11、充电电池12和电池托盘13，但并不限定于此，也可以为任何其它需要冷却的部件。
如图1和图2所示，该冷却组件包括框架8，框架8围成若干充电区域，每个充电区域内放置一个充电仓1，主输入管4、主输出管5排布于框架8内。先通过框架8隔离出若干充电区域，再在每个充电区域安装一个充电仓1，而各种管路(比如主输入管4、主输出管5)可以布置在框架8内或固定在框架8上，沿框架8的延伸方向布设。框架式结构，结构简单，便于充电仓的安装和管路布置。
具体而言，框架8包括若干立柱81和若干横杆82，立柱81竖向设置，横杆82横向设置，立柱81与横杆82的交叉处相连接，主输入管4、主输出管5沿立柱81、横杆82的延伸方向布设。通过上述方式，可以将若干充电仓1阵列排布，而主输入管4、主输出管5的布线距离可以控制在较短的距离。
其中，框架8还围成控制室9，冷却单元3放置于控制室9内。
如图4所示，冷却组件还包括切断阀10，切断阀10设置于冷却管路6的入口；充电仓1内还设有传感器20、阀门控制器30，传感器20用于检测充电仓1内是否有充电电池12并生成第一信号或第二信号，第一信号表示充电仓1内有充电电池12，第二信号表示充电仓1内没有充电电池12，传 感器20还用于将生成的第一信号或第二信号传送给阀门控制器30；阀门控制器30用于接收到第一信号后控制切断阀10打开，阀门控制器30还用于接收到第二信号后控制切断阀10关闭。切断阀10设于冷却管路6上，传感器20设于充电仓1内靠近充电电池12的位置。
当传感器20检测到充电仓1内有充电电池12时，传感器20生成第一信号并传送给阀门控制器30，阀门控制器30接收到第一信号后控制切断阀10打开，令冷却管路6导通。当传感器20检测到充电仓1内没有充电电池12时，传感器20生成第二信号并传送给阀门控制器30，阀门控制器30接收到第二信号后控制切断阀10断开，令冷却管路6截断。通过设置切断阀10，可以保证只有在充电仓1内有充电电池12时才能使冷却管路6导通，保证了冷却系统的安全性，避免了误操作带来的损失。传感器20可以为接近传感器或光电传感器。
如图4所示，当充电模组11、充电电池12和电池托盘13同时作为冷却对象2，充电模组11、充电电池12对应的冷却管路6的入口设置有切断阀10；充电仓1内还设有温度感应器40，温度感应器40用于检测充电电池12的温度并在充电电池12的温度超过阈值时生成超温信号，温度感应器40还用于传送超温信号给阀门控制器30；充电仓1内还设有托盘切断阀50，托盘切断阀50设置于电池托盘13对应的冷却管路6的入口，阀门控制器30还用于接收到超温信号后控制托盘切断阀50打开。温度感应器40可为光纤温度传感器或其它温度传感器。温度传感器40有多个测温点，多个测温点分散于充电电池12的内部或外部的多个区域，根据检测到充电电池12的多个温度中的最高温度作为温度传感器40的温度。
在正常充电模式，即在充电仓1内有充电电池12时，阀门控制器30控制充电模组11、充电电池12所对应的切断阀10打开，令充电模组11、充电电池12的冷却管路6导通，开启冷却模式。若充电电池12的温度超过某个阈值，温度感应器40发送超温信号给阀门控制器30，阀门控制器30控制 托盘切断阀50打开，令电池托盘13对应的冷却管路6导通，通过对位于充电电池12下方的电池托盘13的冷却，加强对充电电池12的冷却。
上述冷却组件，采用管路冷却的方式对充电仓内的多个冷却对象进行热交换，所有冷却对象的冷却管路均接入一个大的回路中，有利于热回收，节省能源，管路布局简单，整个冷却组件空间占比小，利用率高。将上述冷却组件应用于充换电站、储能站时，能解决充换电站、储能站的温度控制效果差，温控效率低的问题。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
