具体实施方式
参考图1,示出了一种用于冷却电池模块16的***10。***10包括蓄存器12、泵14以及导管17、18和19。蓄存器12在其中容纳流体。泵14从蓄存器12经由导管17泵送流体。此后,泵14将流体经由导管18泵送到电池模块16中。电池模块16包括将在下面更加详细地说明的冷却集管40、热交换器和冷却集管42。冷却集管40被构造为通过流体联接到电池模块16中的相应的热交换器中的每一个热交换器的每一个孔口螺钉提供基本相等的流体流率,以使其中的电池单元具有从电池单元去除的基本相等量的热能。因此,电池模块16中的所有电池单元均被维持在基本类似的温度下,使得电池单元具有均匀 的包括输出电压的操作特性。冷却集管42从电池模块16中的热交换器通过流体联接到热交换器的孔口螺钉接收已加热的流体,并且将已加热的流体通过导管19输送回蓄存器12。电池单元组件被定义为在其中具有电池单元的壳体。电池模块被定义为被物理或者电联接到一起的至少两个电池单元组件。
参考图2,电池模块16包括电池单元组件20、22、24、26、28、30、32、34和36以及冷却集管40和42。因为电池单元组件20、22、24、26、28、30、32、34和36具有基本类似的构造,所以在下面将仅仅更加详细地描述电池单元组件20。参考图3,电池单元组件20包括框架部件60、电池单元62、紧固部件64、电池单元66、框架部件68、紧固部件70、热交换器72、电池单元74和框架部件76。框架部件60和68被设置成在其间支撑电池单元62、紧固部件64和电池单元66。框架部件68和76被设置成在其间支撑紧固部件70、热交换器72和电池单元74。在一个示例性实施例中,电池单元62、66、74是锂离子电池单元。在操作期间,冷却集管提供通过热交换器72的预定的流体流率,从而将热能从热联接到热交换器72的电池单元62、66和74去除,以将电池单元62、66和74维持在基本类似的温度下。
参考图4和5,现在将说明冷却集管40的结构。冷却集管40包括:集管部分80;多个孔口螺钉,例如孔口螺钉82、84;盖板86;垫圈88;和多个O形环,例如O形环89。
集管部分80包括周壁90、联接到周壁90的后壁92和联接到后壁92的分流器94。在一个示例性实施例中,集管部分80由塑料构成。当然,在替代实施例中,集管部分80可由其它材料例如钢、陶瓷或者例如金属合金构成。周壁90包括前端110和后端112。此外,周壁90具有顶部,孔114延伸通过所述顶部。孔114从泵14(图1所示)接收流体。进而,周壁90包括多个螺纹孔150、152、154、156、158、160、162、164,所述多个螺纹孔150、152、154、156、158、160、162、 164延伸到周壁90的前端110中,以在其中接收安装螺钉,从而将盖板86联接到集管部分80。
参考图6和7,后壁92包括延伸通过后壁92的出口孔180、182、184、186、188、190、192、194和196,以通过所述出口孔180、182、184、186、188、190、192、194和196接收孔口螺钉。孔口螺钉分别将流体从冷却集管40的内部区域输送到电池单元组件20、22、24、26、28、30、32、34和36。应该指出,虽然仅仅示出了孔口螺钉82、84,但是孔180、182、184、186、188、190、192、194和196中的每一个均将具有延伸通过其的相应的孔口螺钉。参考图2、6和7,延伸通过孔180、182、184、186、188、190、192、194和196的孔口螺钉分别被接收在分别位于电池单元组件20、22、24、26、28、30、32、34、36中的孔280、282、284、286、288、290、292、294、296中。孔280、282、284、286、288、290、292、294、296与电池模块16中的相应的热交换器流体连通。因为孔口螺钉具有基本类似的结构,所以将仅仅描述孔口螺钉82的结构。具体来说,参考图5,孔口螺钉82包括端头部分230、螺纹部分232以及延伸通过端头部分230和螺纹部分232的孔234。因此,孔口螺钉能够实现在冷却集管40的内部区域和电池模块16中的热交换器之间的流体连通。在一个示例性实施例中,孔口螺钉由钢构成。当然,能够设想用于构造孔口螺钉的其它材料。
参考图6,分流器94联接到后壁92,并且从后壁92朝向周壁90的前端110延伸。分流器94设置在进口孔114下面。分流器94被构造为从进口孔114接收流体,并且对流体进行分流,从而分别通过出口孔180、182、184、186、188、190、192、194和196到电池单元组件20、22、24、26、28、30、32、34和36中的相应的热交换器获得了基本相等的流体流率,以均匀地冷却电池单元组件。在一个示例性实施例中,分流器94包括板210,板210带有相互隔开的、在其顶表面上的凹槽212、214、216。凹槽212、214、216从板210的邻近于后壁92的端部朝向盖板86延伸。此外,在一个示例性实施例中,分流 器94被构造成使得通过每一个出口孔获得的流体流率在第一流率的±5%内。
参考图5,盖板86联接到周壁90的前端110。在一个示例性实施例中,盖板86由塑料构成。当然,在替代实施例中,盖板86能够由其它材料例如钢、陶瓷或者例如金属合金构成。在一个示例性实施例中,盖板86包括延伸通过盖板86的孔250、252、254、256、258、260、262、264。螺栓300、302、304、306、308、310、312和314延伸通过盖板88的相应的孔250、252、254、256、258、260、262和264以及集管部分80的相应的孔150、152、154、156、158、160、162和164,以将盖板88联接到集管部分80。
参考图1和2,冷却集管42具有与冷却集管40的结构基本类似的结构。冷却集管42从电池模块16的电池单元组件中的热交换器接收已加热的流体,并且使已加热的流体经由导管19返回蓄存器12。
电池模块10和用于冷却电池模块的方法提供优于其它电池模块和方法的实质性优点。具体来说,该电池模块和方法提供以下技术效果:利用孔口螺钉将冷却集管流体和物理联接到电池模块中的热交换器,以将流体输送到热交换器从而冷却电池模块。
虽然已经参考示例性实施例描述了本发明,但是本领域技术人员将会理解,在不偏离本发明的范围的情况下,可以作出各种改变,并且等价元件可以替代其元件。另外,在不偏离其基本范围的情况下,可以对于本发明的教导作出许多变型以适合于具体的情况或者材料。因此,期望本发明不限于所公开的用于实现本发明的具体实施例,而是本发明将包括落入所附权利要求的范围内的所有实施例。而且,术语第一、第二等的使用被用于使元件相互区别。此外,术语一、一个等的使用并不表示数量的限制,而是实际上表示存在至少一个所提及的项目。
