在其中一个实施例中，热管理部件包括排气空间，排气空间用于接收或引导电池单体的排放物，且排气空间被构造为能够允许电池单体的排放物与第二换热部进行热交换。由此，电池单体的排放物经由排气空间接收或引导，并能够与第二换热部进行热交换，可有效实现对电池单体的排放物的热管理，避免因电池单体热失控产生的失控气体的温度过高而增加电池的内部温度。
在其中一个实施例中，第二换热部包括接口件和容纳腔，容纳腔用于容纳换热介质，接口件用于连通容纳腔和排气空间，以使换热介质能够经由接口件到达排气空间。可利用接口件将容纳腔内的换热介质释放到排气空间，以便该换热介质能够与排气空间内接收或引导电池单体的排放物进行热交换。

可以理解的是，容纳腔222内的换热介质可经由接口件221的进口和接口件221的出口2211释放至排气空间2311内。比如接口件为喷嘴，可以将容纳腔222内的换热介质喷淋至排气空间2311内，以便与排气空间2311内接收或引导电池单体110的排放物进行热交换。
在一些实施例中，排气空间2311沿第一方向F 1延伸，接口件221的出口方向相交于第一方向。

在另一些实施例中，开关部为电致开关，比如设置于接口件221的出口2211上的电池开关，电致开关被配置为能够在电池单体110发生热失控时处于打开状态。
当电池单体110发生热失控时，电池单体110的排放物能够流入排气空间2311内，使得位于排气空间2311内的出口2211上的电致开关能够处于打开状态，进而使接口件221内的换热介质通过出口2211流入至排气空间2311内，以使电池单体110的排放物的温度得以下降，避免电池10的内部温度过高，减小了电池10的安全隐患。

上述“接收部240”是指能够挡设于相邻的两个电池单体110的泄压机构111之间的部件，以防止相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷，若电池模块100的电池单体110设置有多个，接收部240可以为沿多个电池单体110的排布方向延伸的一个整体部件。接收部240也可以设置多个，多个接收部240沿同一电池模块100的多个电池单体110的排布方向间隔设置，且多个接收部240与电池单体110的泄压机构111一一对应，每一接收部240挡设于对应的电池单体110的泄压机构111，以避免相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷。当然，接收部240也可以是其他能够防止相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷的部件，在此不作具体限制。
利用接收部240，可防止相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷，且电池单体110的泄压机构111喷出的排放物能通过通气孔241流入排气空间2311内， 以便喷释放至排气空间2311内的换热介质与这部分排放物发生热交换，进而使电池单体110喷出的排放物的温度大大地下降，避免电池10的内部温度过高，极大地减小了电池10的安全隐患。
另外，从电池单体110的泄压机构111喷出的排放物经由换热孔2101、接收腔242和通气孔241流入排气空间2311内，并能够与喷淋至排气空间2311内的换热介质发生热交换，经过热交换的混合气体能经由排气空间2311排至集气腔2322内，以进行集中处理。当集气腔2322内的气体压力达到预设压力值时，集气腔2322通过泄压部件233与外界环境相连通，可以利用泄压部件233进行泄压，提高电池10的可靠性和安全性。
在一些实施例中，请参阅图4，接收部240与第一换热部210围设出一侧具有开口的接收腔242，接收腔242的开口通过第一换热部210的换热孔2101与电气腔2321相连通，接收腔242远离该开口的一侧设有与排气空间2311相连通的通气孔241。
由此，从电池单体110的泄压机构111喷出的排放物经由换热孔2101、接收腔242和通气孔241流入排气空间2311内，并能够与释放至排气空间2311内的换热介质发生热交换，经过热交换的混合气体能经由排气空间2311排出，以进行集中处理，如此，能利用热管理部件201使电池单体110喷出的排放物的温度大大地下降，避免电池10的内部温度过高，极大地减小了电池10的安全隐患。
在一些实施例中，通气孔241与相邻的电池单体110的泄压机构111错位布设。
能更好地避免相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷，且能使排放物呈弯折状流入排气空间2311内，以降低排放物的流速，提高电池10的安全性。
在一些实施例中，请参阅图6，每一电池模块100包括沿第三方向F 3间隔布设的多个电池单体110，接收部240上设有与相邻的电气腔2321内的电池单体110一一对应的多个通气孔241，通气孔241与对应的电池单体110的泄压机构111沿第三方向F 3错位布设。
由于通气孔241与对应的电池单体110的泄压机构111沿第三方向F 3错位布设，在排放物通过通气孔241流入排气空间2311内的过程中，排放物能呈弯折状地流向排气空间2311内，能很好地避免相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷。
在一些实施例中，请参阅图4，热管理部件201包括位于排气空间2311内的两个接收部240，热管理部件201的两个第一换热部210与两个接收部240一一对应，接收部240与对应的第一换热部210围设出一侧具有开口的接收腔242，接收腔242的开口通过对应的第一换热部210的换热孔2101与电气腔2321相连通，接收腔242远离该开口的一侧设有与排气空间2311相连通的通气孔241。
在一些实施中，请参阅图11，相邻的两个接收部240上的通气孔241沿第三方向F 3错位布设，且均与对应的电池单体110的泄压机构111沿第三方向F 3错位布设。
一方面，接收部240上的通气孔241与对应的电池单体110的泄压机构111沿第三方 向F 3错位布设，能更好地防止相邻的两个电池单体110的泄压机构111喷出的排放物发生对喷，另一方面，由于两个接收部240上的通气孔241沿第三方向F 3错位布设，能够避免通过两个接收部240上的通气孔241流入排气空间2311内的排放物彼此发生对喷和扰动。
在一些实施例中，每一电池模块100包括沿第三方向F 3间隔布设的多个电池单体110，第二换热部220上设有沿第三方向F 3间隔设置的多个接口件221，每一接口件221的出口2211沿第二方向F 2设置，且同一第二换热部220上的全部接口件221与相邻的电池模块100的全部电池单体110的泄压机构111一一对应，第二方向F 2与第三方向F 3呈角度设置。
第二方向F 2与第三方向F 3彼此垂直，第三方向F 3可平行于电池10的长度方向，第二方向F 2可平行于电池10的宽度方向，当然，也可以是，第三方向F 3可平行于电池10的宽度方向，第二方向F 2可平行于电池10的长度方向。
由于同一第二换热部220上的全部接口件221与相邻的电池模块100的全部电池单体110的泄压机构111一一对应，使得当电池单体110发生热失控时，排放物会通过电池单体110的泄压机构111流入电气腔2321内，进而能够流入排气空间2311内位于对应的接口件221处，以便对应的接口件221能够在电池单体110发生热失控时向排气空间2311内释放换热介质，如此，接口件221能够及时地响应于对应的发生热失控的电池单体110，能更好地避免电池10的内部温度过高，减小了电池10的安全隐患。
接口件221的出口2211和对应的电池单体110的泄压机构111的中心轴线呈角度设置。
在电池单体110发生热失控时，对应的接口件221能够向排气空间2311内喷淋换热介质，由于接口件221的出口2211与对应的电池单体110的泄压机构111的中心轴线呈角度设置，从接口件221的出口2211喷出的换热介质不会朝向泄压机构111喷淋，且能很好地与从泄压机构111喷出的排放物在排气空间2311内交汇，既能避免电池10的内部温度过高，又能避免两股气流产生扰动，能有效降低安全隐患。
在一些实施例中，电池单体110的泄压机构111呈弯折状指向对应的接口件221。
如此设置，可使从泄压机构111喷出的排放物能够沿弯折状的路径流向接口件221，并与对应的接口件221的出口2211喷出的换热介质在排气空间2311内交汇，能降低泄压机构111喷出的排放物的流速，进一步避免两股气流产生扰动。
在一些实施例中，热管理部件201包括沿第二方向F 2间隔设置的两个第二换热部220，电池模块100的电池单体110的泄压机构111在相邻的热管理部件201上的正投影位于该热管理部件201的两个第二换热部220之间，每一第二换热部220设有多个接口件221。
可以理解，两个第二换热部220位于电池单体110的泄压机构111沿第二方向F 2的相对两侧，其中，第二方向F 2可平行于电池单体110的宽度方向。
如此设置，在电池模块100的电池单体110发生热失控时，从电池单体110的泄压机 构111喷出的排放物可流入排气空间2311内，可利用两个第二换热部220的接口件221向排气空间2311内喷淋换热介质，可提高换热效果，能更有效地降低安全隐患。
在另一些实施例中，本申请一实施例提供的电池10，包括多个电池单体110和上述的热管理部件201。
在一些实施例中，电池10包括两个电池模块100和箱体组件200，且箱体组件包括热管理部件201和热管理框体231，热管理部件201设于两个电池模块100之间，热管理部件201包括与电池模块100一一对应的两个第一换热部210，以及第二换热部220。箱体组件200包括两个电池框体232，两个电池框体232连接于热管理框体231沿第一换热部210的厚度方向的相对两侧，热管理框体231与两个第一换热部210围设出排气空间2311，第一换热部210与相邻的电池框体232围设出用于容置对应的电池模块100的电气腔2321，且第一换热部210上设有分别与电气腔2321和排气空间2311相连通的换热孔2101，第二换热部220设于排气空间2311内，第二换热部220设有接口件221，接口件221被配置为能够在电池单体110发生热失控时向排气空间2311内喷淋换热介质，第一换热部210上的换热孔2101和对应的电池单体110的泄压机构111一一对应。
该电池10使用时，第一换热部210能够与电池模块100的电池单体110接触，以与电池单体110进行热交换。若电池单体110发生热失控时，电池单体110喷射出的排放物经由换热孔2101流入排气空间2311内，这部分排放物能够与换热孔2101的侧壁发生热交换，以对排放物进行一次降温处理。由于接口件221被配置为能够在电池单体110发生热失控时向排气空间2311内喷淋换热介质，那么，接口件221能够向排气空间2311内喷淋换热介质，接口件221喷淋至排气空间2311内的换热介质能够与流入排气空间2311内的排放物发生热交换，以对排放物进行二次降温处理。该换热介质和经过二次降温处理的排放物能够一起排出排气空间2311外，以进行集中处理，如此，能利用热管理部件201对两个电池模块100的电池单体110和电池单体110喷出的排放物进行热管理，避免电池10的内部温度过高，极大地减小了电池10的安全隐患。
本申请一实施例提供的用电装置，包括上述的电池10。
