具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考图1-图6细描述根据本公开实施例的用于车辆1000的电池包100。其中，车辆1000包括地板200，电池包100安装在车辆1000的地板200的下表面上。
如图1、图3和图4所示，根据本公开实施例的电池包100包括：电池托盘10和电池模组20，电池托盘10构造有进风口11、出风口12，其中，如图1、图3-图5所示，出风口12可以为多个，而且多个出风口12在电池模组20的一侧间隔开分布。
电池模组20固定在电池托盘10上，其中电池托盘10内构造有第一风道30，电池模组20与地板200之间构造有第二风道40，第一风道30与第二风道40相连，而且第一风道30的进口端构造为进风口11，第二风道40的出口端构造为出风口12，第一风道30和第二风道40构成的冷却风道至少部分地环绕电池模组20设置。也就是说，电池包100与地板200之间形成冷却风道，冷却风道的进风口11和出风口12均形成在电池托盘10上，但是冷却风道至少部分地环绕电池模组20，这样当车辆1000在行驶过程中时，外部环境的风可以通过进风口11进入到冷却风道内，冷却风道可以将风送入到电池模组20周围，从而可以带走电池模组20的热量，进而可以有效降低电池模组20的温度，可以提高电池模组20的放电性能。
需要说明的是，随着车速的改变，进风口11的进风效率也相应变化，从而可以至少一定程度上能够实现实时调节送风程度，进而可以更好地提升电池包100的散热效果。
根据本公开的一个可选实施例，如图1和图2所示，电池模组20包括多个电芯和一体式的导热件50，多个电芯容纳在导热件50内，而且导热件50固定在电池托盘10的上方。也就是说，多个电芯可以直接设置在导热件50内，然后导热件50内固定在电池托盘10上，这样当电芯充放电时，导热件50可以将电芯的热量直接传递给电池托盘10上，从而可以有利于电芯的散热。而且如此设置的导热件50结构简单，成本低，电芯布置可靠。
在电芯充电时，车辆1000一般不行驶，可以配合外部风机或在车上另设风机使空气流动以借助本申请的电池托盘达到散热的目的。
在一些实施例中，导热件50的两侧设置有安装吊耳，安装吊耳与电池托盘10通过紧固件固定。通过紧固件固定，可以使得导热件50在电池托盘10上固定可靠，从而可 以使得电芯位置固定可靠。
还有，如图2所示，导热件50可以包括多个导热垫片51，相邻的导热垫片51之间限定出电芯安装槽。由此，每个电芯可以放置在电芯安装槽内，从而可以保证电芯的安装稳定性。而且如此设置的导热垫片51导热效果好，有利于电芯的散热。
根据本公开的另一个可选实施例，如图3和图4所示，电池托盘10一体成型有导热件50，电池模组20包括多个电芯，多个电芯容纳在导热件50内。也就是说，导热件50和电池托盘10为一体成型结构，这样电芯直接通过导热件50放置在电池托盘10上，从而可以有效简化电池包100的结构，而且可以使得电芯的散热效果较好。
其中，如图3所示，电芯可以竖向布置，这样多个电芯在水平方向上依次排布，如图4所示，电芯还可以横向布置，这样多个电芯可以在竖向方向上层叠布置。
在一些实施例中，如图2至图4所示，导热件50包括多个导热垫片51，相邻的导热垫片51之间限定出电芯安装槽。由此，每个电芯可以放置在电芯安装槽内，从而可以保证电芯的安装稳定性。而且如此设置的导热垫片51导热效果好，有利于电芯的散热。
下面结合附图描述一下电池托盘10的布置形式。
如图5所示，电池托盘10包括：托盘本体13和导风装置14，电池模组20固定在托盘本体13的上方，导风装置14与托盘本体13之间限定出第一风道30且还限定出第一风道30的出口端。也就是说，托盘本体13用于固定电芯，导风装置14可以将外部环境的风导入电池托盘10，然后从第一风道30进入第二风道40内，其中第一风道30的出口端即第二风道40的入口端。通过设置导风装置14，可以保证外部环境的风有效进入电池包100内部，从而可以有利于电池模组20的换热。
可选地，地板200具有上凹部210，电池模组20嵌入上凹部210内，托盘本体13固定在上凹部210的下开口处。由此，托盘本体13和电芯位置布置可靠，而且导风装置14可以露出地板200的下表面，从而可以有利于风进入到导风装置14内，进而可以有利于电芯的散热。
在一些实施例中，如图1、图3-图5所示，导风装置14可以包括：导风板141和导风片142，导风板141与托盘本体13间隔开，而且导风板141与托盘本体13之间限定出进风口11，导风片142连接在导风板141和托盘本体13之间。由此，导风板141和托盘本体13之间可以限定出一个向车辆1000的前端敞开的进风口11，而且导风片142可以在导风板141和托盘本体13之间进行导风，从而可以提升导风装置14的导风效率。
可选地，如图3-图5所示，导风板141具有底板141b和向上延伸的弯折板141a， 底板141b通过导风片142连接在托盘本体13的下方，弯折板141a和托盘本体13的边缘之间限定出第一风道30的出口端。弯折板141a可以将第一风道30内的风导向第二风道40，而且弯折板141a可以改变送风方向，从而可以有利于风在第二风道40内围绕电池模组20流动，进而可以提升电芯的散热效果。
还有，如图5所示，底板141b相对托盘本体13倾斜设置。可以理解的是，倾斜设置的底板141b能够有利于风进入第一风道30，而且这样可以有利于风从第一风道30进入到第二风道40内。而且如此设置的底板141b可以减缓风在第一风道30内的流动噪音，从而可以提升车辆1000的舒适性。
可选地，如图5所示，底板141b与托盘本体13之间的距离在送风方向上递减。由此，在第一风道30内，底板141b可以不断地引导风的流动，而且可以改变风的流动速度，从而可以使得风更好地进入第二风道40内以与电池模组20进行换热。
根据本公开的一些实施例，如图1和图3所示，底板141b上设置有与出风口12上下正对的底板出口141c。这样风在与电池模组20完成换热后，可以从出风口12和底板出口141c出去，从而可以完成风的循环，可以使得风不断地与电池模组20换热。另外，为了避免发生风的干涉，导风片142内部为中空结构，这样导风片142可以连接在出风口12和底板出口141c之间，从而可以起到导风作用，而且可以解决风的干涉。
如图6所示，根据本公开实施例的车辆1000，包括：底板141b和上述实施例的用于车辆1000的电池包100，地板200具有上凹部210，电池模组20嵌入上凹部210内，电池托盘10的托盘本体13固定在上凹部210的下开口处。由此，电池包100能够在车辆1000的地板200处于外部环境换热，可以使得外部环境的风有效带走电池模组20的热量。
