在另一实施例中,侧板141的数量为三个,架体11的左右两侧以及后侧均设有该侧板141,三个侧板141均为风道壳体22,三个侧板141内的通风通道220均相连通,或三个侧板141内的通风通道220彼此独立,风机21的数量为三个,每个风机21与一个侧板141内的通风通道220相连通。
在另一实施例中,侧板141的数量为三个,架体11的左右两侧以及后侧均设有该侧板141,左右两侧相对的侧板141均为风道壳体22,两个相对的侧板141内的通风通道220彼此独立,风机21的数量为两个,每个风机21与一个侧板141内的通风通道220相连通。
在一实施例中,风道壳体22包括相连通的第一壳体221和第二壳体222,第一壳体221沿水平方向延伸并与风机21的出口相连接,第二壳体222沿架体11的高度方向延伸,出风口2201开设于第二壳体222靠近承载件12的一侧面。如此设置,可减小风道壳体22的占用空间,同时便于将风道壳体22安装于架体11上。第二壳体222的左右两端固定于架体11上,风机21通过安装板3固定于架体11的底部,第一壳体221的第一端与第二壳体222固定连接,第一壳体221的第二端与风机21固定连接,从而实现稳定安装。
第二壳体222靠近承载件12的一侧面为平面,该平面能够在与承载件12近距离设置的情况下避免与电池包100发生干涉,由于出风口2201与电池包100的距离较近,可保证出风口2201的气流直接吹向电池包100,提高散热效果。此外,可以理解的是,将第二壳体222设计为由平面板材组装而成,还可以便于第二壳体222的加工成型,降低成本。
可以理解的是,当出风口2201的数量过多时,从出风口2201吹出的气流的速度会减小,使得该气流可能未充分流经电池包100在架体11前后方向的所有部位,进而可能造成电池包100远离出风口2201的部位的散热效果较差。而当出风口2201的数量过少时,出风口2201的总出风量较小,风冷效果也会降低。
基于此,在一实施例中,多个出风口2201包括两个第一出风口2201a和两个第二出风口2201b,每个第一出风口2201a沿架体11的高度方向延伸;每个第二出风口2201b沿水平方向延伸。两个第一出风口2201a沿水平方向间隔设置并与承载件12上的电池包100在水平方向的两侧相对应。两个第二出风口2201b沿架体11的高度方向间隔设置并与承载件12上的电池包100在高度方向的两端相对应。如此设置,可兼顾出风口2201的出风速度以及出风量,充分提高风冷的散热效果。
在另一实施例中,第一出风口2201a的数量还可以是三个、四个或五个等,具体可根据电池包100的尺寸进行设计,其中有两个第一出风口2201a沿水平方向间隔设置并与承载件12上的电池包100在水平方向的两侧相对应,其余第一出风口2201a位于该两个第一出风口2201a之间。第二出风口2201b的数量也可以是三个、四个或五个等,具体可根据电池包100的尺寸进行设计,其中有两个第二出风口2201b沿架体11的高度方向间隔设置并与承载件12上的电池包100在高度方向的两端相对应,其余第二出风口2201b位于该两个第二出风口2201b之间。
继续如图2结合图1所示,承载件12包括承载部121和阻挡部122,承载部121设置为承载电池包100,承载部121远离风道壳体22的一侧边具有取放电池包100的取放口,承载部121的其余侧边连接有向上延伸的阻挡部122。即承载部121的前侧具有取放口,承载部121的其余三边具有阻挡部122。如此设置,既能够方便将电池包100放置于承载件12的承载部121上,又可以避免电池包100从承载部121的其余三边掉落,保证电池包100的稳定性。
在一实施例中,机架1还包括支撑件13,电池包100的左侧和右侧均可拆卸地连接有该支撑件13,支撑件13能够与架体11相抵接,以对电池包100进行限位,避免电池包100在承载件12上左右晃动。
在一实施例中,电池包100左右两侧的支撑件13数量为至少一个,具体可根据电池包100的高度以及支撑件13的高度进行设计,在此不作限制。
在一实施例中,电池包100上设有固定件101,固定件101与支撑件13可拆卸固定连接。
在一实施例中,固定件101为L型板件,其第一支臂固定于电池包100上,其第二支臂具有连接柱,连接柱具有螺纹孔,支撑件13具有与该螺纹孔相连通的通孔,利用螺栓穿过通孔与螺纹孔螺纹连接,可以实现将支撑件13与固定件101固定连接。固定件101还可以是其他形状的板件,只要能够实现固定件101与支撑件13之间的可拆卸固定连接即可,在此不作限制。
