Description

用于机动车辆、尤其是用于冷却的温度调节装置
本发明涉及一种尤其是用于在操作期间易于散发热量的电气部件的温度调节装置(尤其是冷却装置)，尤其是涉及一种用于冷却机动车辆的至少一个电池或电池单元的装置。
车辆电池、特别是用于电动车辆或混合动力车辆的车辆电池应当尽可能地维持在期望的温度，这就是为何使用所谓的车辆电池冷却装置。这些冷却装置包括冷却板，冷却液体通过这些冷却板循环。冷却板尽可能无间隙地安装在电池的外侧，以便散热或加热电池。冷却装置是已知的，在这些冷却装置中，冷却板由通常直接彼此固定的两个板部分构成。在这种情况下，第一板部分优选地是平坦的，并且第二板部分优选地是具有曲折凹陷的冲压或变形的金属片材。所述凹陷由固定到冲压的板部分的平坦板部分封闭，从而形成制冷剂管道。专利EP 2 828 922 B1描述了这样的装置。
本发明旨在改进这种类型的装置。
因此，本发明提出了一种用于在操作期间易于散发热量的电气部件、尤其是用于电能储存模块的温度调节装置(尤其是冷却装置)，此装置具有上板和连结至该上板的下板，使得这些板一起形成多个循环通道，该多个循环通道用于传热流体、尤其是制冷剂流体、尤其是选自以下制冷剂流体的流体：R134a、R1234yf和R744，在该装置中，这些通道中的至少一些通道通向至少一个分流腔室中，借助于该至少一个分流腔室，该流体可以实现分流，在该装置中，该分流腔室和这些通道中的至少一者具有机械增强元件，该机械增强元件形成于此分流腔室的壁上或这些通道之一的壁上，此增强元件被设计成提高该腔室和/或该通道对高压作用下的潜在变形的机械阻力。
在这种类型的装置中，应力集中在流体必须进行分流或逆转或采用分支路径(例如，非线性路径)的区中、尤其是在流体流动被分配、收集或逆转的区中。为了避免这些区中出现变形，使用了优选地通过冲压获得的特定形状，这些特定形状即根据本发明的增强元件。
根据本发明的一方面，增强元件在分流腔室的整个高度和通道的整个高度之上延伸。
根据本发明的一方面，分流腔室和通道各自具有在流体的流动方向上测量到的长度，并且增强元件仅在分流腔室的长度的部分和通道的长度的部分之上延伸，长度的部分分别尤其是小于此长度的一半、或小于此长度的四分之一或十分之一。
换言之，增强元件相对于整个分流腔室或通道而言相对较小。
根据本发明的一方面，多个增强元件沿着分流腔室和/或通道中的一个通道设置，此多个增强元件例如彼此均匀地间隔开。
根据本发明的一方面，形成于分流腔室上的这些增强元件全部相同。
根据本发明的一方面，当在垂直于板的方向上观察时，增强元件具有圆形轮廓，该圆形轮廓具有朝向分流腔室的外部或相关联的通道的外部定向的凹面。
根据本发明的一方面，凹面的曲率半径尤其是值小于5毫米(mm)、尤其是小于2mm。
根据本发明的一方面，两个相邻通道在连接区段中连接至分流腔室，使得通道之间的间隙存在于分流腔室中、在两个连接区段之间，并且增强元件位于通道之间的此间隙中、尤其是位于通道之间的此间隙的中间处。
根据本发明的一方面，增强元件被设置成沿着线(该线沿着分流腔室延伸)均匀地间隔开。
根据本发明的一方面，分流腔室的流体通路截面在每个增强元件的两侧都增加。
根据本发明的一方面，两个相邻流体通道连接至分流腔室，并且形成于分流腔室的侧向壁上、面向这两个流体通道的增强元件被设置成能够将内切假想圆邻近两个相邻通道和面向这两个相邻通道的增强元件定位，此内切圆的直径尤其是小于15mm。
根据本发明的一方面，(多个)增强元件是通过冲压形成的。
优选地，增强元件定位于一个通道与另一个通道或分流腔室连结的连结区中，此增强元件尤其是面向此通道。
值得注意地，当数量为N的连续的通道连接至分流腔室时，设置数量为M的连续的增强元件，其中M＝N、或者M小于N。
根据本发明的一方面，增强元件沿着直线设置、尤其是彼此等距地设置。
根据本发明的一方面，增强元件使得可以具有较大的流体通路截面，同时仍确保对变形的良好机械阻力。制冷剂流体通路截面的这种增加伴随着所产生的压降的减少。相对于没有增强元件的常规设计，通路截面的增加可以为大约+40％。
本发明还使得可以提高形状系数。
根据本发明的一方面，分流腔室可以被设计成使得可以使流体流动逆转、或者使得可以在流体入口或出口处收集流体。在后一种情况下，分流腔室可以被称为流体入口或出口收集腔室。
本发明的另一个主题是一种系统，该系统具有：在操作期间易于散发热量的电气部件、尤其是电能储存模块；以及上文所描述的冷却装置，该冷却装置被设计成使该部件冷却下来，此部件或电池与冷却装置的上板热接触。

冷却装置具有入口区30，该入口区用于制冷剂流体进入通道，此入口区形成于两个板11和12之间。此流体入口区30被设计成向通向分流腔室20中的所有流体循环通道13(具体地，流体朝向分流腔室流动的通道)供应。此入口区30为通道分组14所共用。冷却装置具有出口区31，该出口区用于制冷剂流体离开通道，此出口区形成于两个板11和12之间。此流体出口区31被设计成引导流体离开源自分流腔室的所有流体循环通道13。此出口区31为两个通道分组所共用。入口区30和出口区31分别邻近入口孔32和出口孔33。入口孔32和出口孔33与管连接器块6相连。
下板2具有圆形截面区37、尤其是冲压区，以与上板一起形成通道13。入口区30和出口区31包括下板12的冲压区。
优选地，传热流体可以选自名称为R134a、R1234yf和R744的制冷剂流体。
电池单元例如包括用于混合动力车辆的多个锂离子(Li-ion)电池。在另一个实施例中，多个电池单元是在电池供电的电动车辆中使用的锂离子电池。分流腔室20、和/或入口区30、和/或出口区31(在适当的情况下)包括增强元件，这些增强元件用于增强可能具有较大截面的这些区中的机械强度。

分流腔室20具有机械增强元件27，这些机械增强元件形成于此分流腔室20的壁上，每个增强元件27被设计成提高腔室对高压作用下的潜在变形的机械阻力。
每个增强元件27在分流腔室20的整个高度之上延伸。
分流腔室20和通道13各自具有在流体的流动方向上测量到的长度，并且每个增强元件27仅在分流腔室20的长度的部分(在这种情况下，该部分小于相关联的分流腔室20的总长度的1/5、或1/8、或1/10)之上延伸。
增强元件27沿着分流腔室20设置，此多个增强元件彼此均匀地间隔开。

凹面29的曲率半径尤其是值小于5mm、尤其是小于2mm。该曲率半径是图3中的虚线圆的曲率半径，值为1.1mm。
两个相邻通道13在连接区段18中连接至分流腔室20，使得通道之间的间隙19存在于分流腔室20中、在两个连接区段18之间，并且增强元件27位于通道之间的此间隙中(在这种情况下，位于通道之间的此间隙的中间处)。
增强元件27被设置成沿着线36(该线沿着分流腔室20延伸)均匀地间隔开。
增强元件27是通过在对应的板上冲压而形成的。
增强元件27使得可以具有较大的流体通路截面，同时仍确保对变形的良好机械阻力。制冷剂流体通路截面的这种增加伴随着所产生的压降的减少。相对于没有增强元件的常规设计，通路截面的增加可以为大约+40％。
