交叉引用
本申请基于35U.S.C.§119(a)要求于2012年9月7日提交的韩国专利申请第10-2012-0099404号的权益，其全部内容引入本文以供参考。
技术领域
本发明涉及通过冷却或加热电池能够提高用于车辆中的电池的效率的电池***。
背景技术
近来，已在各种工业领域作出努力以便用电力发动机代替内燃机，以帮助解决环境问题。此处，电池在电力发动机中起到燃料替代物的作用，并且在整个电动车和混合动力车用电池的温度增加和降低的过程中，应保持燃料效率比或耐久性的最佳状态。
许多常规电池冷却和加热技术配置成从车辆的内部和外部吸入空气并将空气传递至电池，以便通过空气对流冷却电池。在用于同时冷却和加热电池的现有配置中，如上所述，可在电池外壳内侧布置多个电池组和电力装置。因此，可以将单独的管道布置在吸入部和排出部上，以使用于热交换的空气流路限定在电池组内侧并且使空气经由其流动。
此外，单独的流动通道可以布置在电池组的外部，以使空气流路限定在其中，因此，设计电池***存在限制并且可能达不到用于电池的冷却配置的效率。
例如，在题为“包括径向风机的电池组（A battery pack includingradial fans）”的韩国专利申请第10-2012-006927A号中，涉及包括径向风机的电池组，其中布置径向风机使得冷却空气的输入和输出方向变得与横贯多个电池单元的冷却空气的方向垂直，从而设计更加有效的冷却空气的流路。然而，以电池组的这种配置，须设置用于冷却气流的单独通道和管道，冷却效果可能因很长的冷却气流而降低。而且，即使电池和冷却装置在该配置中布置于一点或分别布置于数点上，空气冷却装置的风机可以布置在引起噪音的后座上。
提供上述项目仅用于帮助理解本发明的背景技术，而不应理解为承认其相应于本发明所属领域的技术人员已经知晓的技术。
发明内容
致力于作出本发明以解决上述与现有技术相关的问题。本发明的目的是提供电池***，其能够使冷却气流最小化并且减少加热和冷却电池***部件所需的空间。
在一个实施方式中，电池***包括：可以阻挡空气的基本上气密的外壳；布置在气密外壳中的多个电池组；形成在气密外壳中的吸入口和排出口；与气密外壳且与车座隔开的基本上气密的冷却装置，其中通过吸入管道和排出管道可以将冷却装置与吸入口和排出口连接，冷却装置可以包括用于循环气密外壳中的空气的鼓风机；以及热电元件，布置在气密冷却装置的空气循环流路上，以冷却或加热循环空气。
气密外壳可以布置在车辆地板一侧，并且冷却装置可以布置在车辆行李厢一侧。吸入口可以布置在气密外壳的下部，经由其可以吸入空气，并且排出口可以布置在气密外壳的上部，经由其可以排出空气。鼓风机可以是径向型风机，其中可以朝向风机中部吸入空气并且向气密外壳一侧排出空气。
冷却装置可以包括吸入管道、排出管道和鼓风机。此外，热电元件可以布置在多个冷却装置的空气流路上。气密外壳、吸入管道、排出管道和冷却装置可以完整地与外部空气阻隔开，从而形成闭合流路。热电元件可以布置在吸入管道或排出管道内。
冷却装置单元可以形成为多个冷却装置，各个冷却装置可以包括吸入管道和鼓风机。管道可以从排出管道分支并且可以与鼓风机连接。此外，热电元件可以布置在各多个冷却装置的空气流路上。而且，热电元件可以布置在吸入管道内。
气密外壳中的电池组单元可以形成为编队（in columns）布置的多个电池组，其中连接管道可以连接电池组的队列。此外，在气密外壳内排出口可以与排出管道连接，对应于电池组单元的各列。连接管道的一端可以与排出口连接，并且其另一端可以分支成与电池组单元的各列连接，其中空气流经各电池组。

下面将参考附图描述根据本发明的示例性实施方式的车辆用电池***。
根据本发明的实施方式的电池***包括：可以阻挡空气的基本上气密的外壳100；布置在气密外壳中的电池组单元700；形成在气密外壳中的吸入口120和排出口140；与气密外壳100且与车座隔开的基本上气密的冷却装置300，其中通过吸入管道220和排出管道240可以将该冷却装置与吸入口120和排出口140连接，冷却装置可以包括用于循环气密外壳100中的空气的鼓风机；以及热电元件500，布置在气密冷却装置300的空气循环流路上，以冷却或加热循环空气。
在根据本发明的电池***中，电池组单元700与冷却装置300基本上隔开，以保证电池的性能并且帮助解决噪音干扰。而且，可以将电池***设计成基本上气密，以形成闭合流路，从而增加电池***的空气冷却效率。
在电池***的一个实施方式中，可以阻挡空气的外壳可以是基本上气密的。电池组单元700可以布置在外壳内。此外，吸入口120和排出口140可以形成在外壳100内。吸入口120和排出口140可以布置在车辆地板F一侧，并且冷却装置300可以布置在行李厢T一侧。电池占据相对大的空间，并且电池可以稳定地布置在车辆后座下方，以降低车辆的重心。而且，为了降低鼓风机320的噪音，冷却装置300可以与行李厢T的一侧隔开。外壳100可以固定至地板F一侧的饰件（trim）或面板上，并且冷却装置300可以布置在行李厢T一侧的隔室的内部或下部。此外，冷却装置300可以布置在行李厢T中，其中来自冷却装置的废热可以操作热电元件500。
此外，吸入口120可以布置在吸入外壳100的下部，经由其可以吸入空气，并且排出口140可以布置在外壳100的上部，经由其可以排出空气。
而且，鼓风机320可以是径向型风机，其中可以朝向鼓风机的中部吸入空气并且向气密外壳一侧排出空气。因此，根据垂直分开的吸入口120和排出口140的位置，鼓风机320可以布置于基本上较小的空间上。
一个实施方式可以包括冷却装置单元A、B，各个冷却装置包括吸入管道220、排出管道240和鼓风机320。此外，热电元件500可以布置在各冷却装置单元A、B的空气流路上，或者热电元件500可以布置在吸入管道220或排出管道240内。
更具体地，冷却装置单元A、B可以包括吸入管道220和鼓风机320、以及分支管道241、242，该分支管道241、242可以从排出管道240分支并且可以分别与鼓风机320连接。此外，热电元件500可以布置在各冷却装置单元A、B的空气流路上，并且热电元件500可以布置在各吸入管道220内。
在该配置中，根据本发明的电池***可以形成闭合流路，其中外壳100、吸入管道220、排出管道240和冷却装置300可以阻挡外部空气的吸入。
在另一实施方式中，电池***可以包括多个鼓风机，其中当一个鼓风机发生故障时，另一鼓风机工作。类似地，电池***可以包括多个热电元件，其中一个热电元件可以在另一热电元件可能已经发生故障时工作以保护电池。而且，当独立控制多个鼓风机和多个热电元件时，可以更加有效地进行冷却装置的冷却和加热。
此外，电池***可以包括：布置在气密外壳100中的电池组单元，其中该电池组单元可以形成队列C、D。而且，连接管道600可以布置在气密外壳100中以连接电池组单元的队列C、D。此外，在气密外壳100内排出口140可以与排出管道240连接，对应于电池组单元的各队列C、D。具体地，连接管道600的一端可以与排出口140连接，并且其另一端可以分支成与电池组单元的各队列C、D连接，其中空气流经各电池组。
在该配置中，通过热电元件500可以冷却从鼓风机320鼓吹的空气，并且通过各吸入管道220和吸入口120，冷却空气可以在电池组单元的队列C、D之间或在电池组单元的队列C、D与气密外壳的内壁之间流动，并且鼓吹的空气可以绕外壳的后部流动并且可以输入到电池组700的后部中。
具体地，空气可以流经电池组单元的内部，并且冷却空气在流经电池组单元的队列C、D时可以进行热交换。通过气密外壳前部的连接管道600，可以在排出口140中收集热交换的空气，然后通过排出管道240在鼓风机320处收集热交换的空气。因此，在气密外壳100内可以将冷却空气有效地供应到电池组单元700，从而冷却外壳100的内部。而且，热交换的空气可以在鼓风机320处被收集，而***漏出气密外壳，并且可以在热电元件500处被冷却以增加冷却效率。而且，吸入管道220和排出管道240可以是隔热的，从而使在冷却空气流经闭合流路时的热损失最小化。
根据如上配置的电池***，电池外壳和鼓风机可以基本上隔开，以降低噪音干扰并且减少用于冷却和加热部件的空间。而且，通过实现最小的冷却气流，可以防止冷却效率降低。换言之，其中布置有电池组并且可以以预定距离隔开冷却装置以保证效率性能的外壳，降低噪音干扰并且通过将电池***设计为闭合流路***而进一步提高空气冷却效率。
尽管参考具体实施方式说明和描述本发明，但本发明所属领域的技术人员应当理解到，可以在不偏离本发明范围的情况下对本发明进行各种改进和变化。
