Description
技术领域
根据权利要求1的前序部分,本发明涉及一种叠板式热交换器,尤其是用于机动车辆的油冷却器、制冷器或冷凝器。
背景技术
叠板式热交换器已经在现有技术中已知,并且例如用作机动车辆中的油冷却器、制冷器或冷凝器。叠板式热交换器在此具有一个叠放在另一个上的若干细长板,在细长板之间形成有空腔。在一个布置在另一个上的空腔中,两种介质(冷却介质和待冷却介质)流动,使得在两种介质之间发生热交换。空腔在此由各个板的表面和表面边缘并且由相邻的支承板限定。在每个板中,形成有四个开口,所述四个开口在一个放置在另一个上的板中彼此对应,并且形成垂直于板的总共四个通道。这些通道中的两个设置为用于一种介质的供给和排出,而这些通道中的两个设置为用于另一种介质至相应的空腔的供给和排出。用于两种介质的空腔在此在叠板式热交换器中交替,并且通道专门流体地与对应的空腔连接。
各个介质从一个开口跨过各个板的表面而流向另一个开口。流动能够是U形的,例如,如在DE102012107381A1中所描述的。为了扩大组成热交换器的板的表面,在板上形成细长的成型件-所谓的凸条。成型件在此平行于各个板的纵向中心轴线而延伸,并且将两个开口彼此隔开。各个介质因此不能直接从一个开口流向另一个开口,并且增强了热交换。替代U形的流动,也能够设置其他流动,就像例如在US5,735,343A中所描述的。在此,凸条将板的表面分隔为两个部分,使得各个介质分离地流过每个部分。
在叠板式热交换器中,至少一种介质分别将其聚集态从气体改变为流体,或者从流体改变为气体,并且体积流量因此而改变。在此,热交换所需的介质的量未被最优地利用,并且叠板式热交换器中的输出与压力比例由此并非最优。
发明内容
因此本发明的目的在于,针对普遍类型的叠板式热交换器指出一种改进的或者至少替代的实施方式,其中克服了所描述的缺点。
根据本发明,该问题由独立权利要求1的主题解决。有益的实施例为从属权利要求的主题。
本发明基于使叠板式热交换器中的流动截面适于流过的介质的聚集状态的主要构思。叠板式热交换器在本文中尤其能够是用于机动车辆的油冷却器、制冷器或者冷凝器。叠板式热交换器具有一个放在另一个上的若干细长板,在细长板之间以交替的方式形成用于两种介质(冷却介质以及待冷却介质)的空腔。所述空腔在各板处分别由板表面和包围壁区域地限定,所述包围壁从板表面凸起并且包围后者。另外,在各板中,以相邻的方式在第一短侧形成两个流动开口,并且在与第一短侧相对放置的第二短侧形成两个通道开口,其中在两个通道开口周围的各板中分别形成从板表面突出到空腔中的圆顶。在至少一个板的板表面上,形成突出到空腔中的细长的分隔成型件,所述分隔成型件从两个流动开口之间的第一短侧沿第二短侧的方向延伸。根据本发明,分隔成型件以45°与90°之间的角度α邻接。
两个短侧通过比两个短侧长的长侧彼此连接。板表面大致为矩形,并且分别地,两个短侧长度相等,两个长侧长度相等。分隔成型件将板表面划分为两个流动区域。在本文中,第一流动区域围绕用于各介质的流入的第一流动开口,并且在分隔成型件与一个长侧之间从第一短侧向第二短侧延伸。第二流动区域围绕用于各介质的流出的第二流动开口,并且在分隔成型件与另一个长侧之间从第一短侧向第二短侧延伸。两个流动区域沿着分隔成型件彼此流体地分离,并且仅在第二短侧处彼此流体地连接。分隔成型件在本文中邻接第一短侧,使得沿着第一短侧没有流动发生,并且各介质在各板中被迫使U形流动。通过分隔成型件具有角度地邻接第一短侧的事实,流动截面沿各介质的流动方向而改变。具体地,流动截面适于各介质的聚集状态,使得能够优化叠板式热交换器中的输出与压力比例,并且能够最优地利用热交换所需的量。在本文中,一个堆叠在另一个上的若干板能够被构造为以便是相同的,或者板与板能够不同。
有益地,能够做出分隔成型件为直线形或者朝向连接两个短侧的长侧弯曲的设置。分隔成型件还能够具有以弯曲角彼此邻接的至少两个直线形的分隔区域。一个分隔区域的长度与分隔成型件的总长度的比例于是处于0与1之间。通过等于0或1的比例,一个分隔区域延续到另一个分隔区域中,使得两个分隔区域中的分隔成型件相当于直线形的分隔成型件。通过弯曲角的适应,在相应的板处的流动以及由此的两个介质之间的热交换能够被优化。弯曲角β在本文中能够在90°与100°之间变化。
有益地,分隔成型件以与短侧的总长度的0.3与0.5之间的比例划分第一短侧。通过0.5的比例,分隔成型件居中地邻接短侧,使得由分隔成型件形成的两个区域至少在第一短侧处具有相同的流动截面。通过较小的比例,分隔成型件在第一短侧处分别偏离一个流动开口或者一个长侧,使得至少在第一短侧处流动截面不同。另外,分隔成型件能够沿第二短侧的方向从第一短侧延伸至长侧的长度的0.2倍至0.8倍。沿第一短侧的方向从第二短侧的长侧的长度的剩余的0.8倍至0.2倍于是相当于连接区域的长度,在所述连接区域中两个流动区域重叠并且彼此流体地连接。
为了优化各介质在各流动区域中的流动以及叠板式热交换器中的热交换,有益地,至少一个流动引导结构能够被布置在至少一个板的空腔中。流动引导结构能够引导各介质通过流动区域并且将其混合。各流动引导结构例如能够为紊流***件。可替代地,各流动引导结构能够形成(例如冲压)在各板的板表面中,突出到空腔中。在本文中流动引导结构能够包括若干凸块状或细长的或波状的成型件。有益地,能够分别在至少一个板的分隔成型件的两侧布置流动引导结构,并且各流动引导结构能够被构造为以便是相同的或不同的。由此,产生各板的各种可能的构造,使得各板中的流动和热交换能够适于各介质,并且适于改变各介质的聚集状态。
在根据本发明的叠板式热交换器的有益的进一步的开发中,能够做出至少一个板的流动开口和/或通道开口具有彼此不同的流动截面的设置。另外,一个叠放在另一个上的板的流动开口和通道开口能够彼此流体地对应,并且叠板式热交换器中的一个叠放在另一个上的板的流动开口和通道开口的流动截面能够逐个板地连续增加或减小。以这种有益的方式,由流动开口和通道开口形成的通道的流动截面能够连续地增加或减小。在本文中各通道的最小流动截面与最大流动截面的比例处于0.25与1之间。以这种有益的方式,各通道的流动截面还能够适于流过的介质的聚集状态。
总之,在根据本发明的叠板式热交换器中,各板中的流动截面能够适于各流过的介质的聚集状态。由此,能够优化叠板式热交换器中的输出与压力比例,并且能够最优地利用热交换所需的量。有益地,叠板式热交换器于是能够分别具有较少或较小的板,而没有减小叠板式热交换器的输出。由此明显产生了成本优势。
本发明的进一步重要的特征和益处从从属权利要求、附图以及通过附图的辅助的相关附图描述显现。
应当理解的是,在没有脱离本发明的范围的情况下,上述的特征以及留待在下文中进一步说明的特征不仅能够用在各个所指出的结合中,而且还能够用在其他结合中或者单独地使用。

图5为根据本发明的叠板式热交换器的板的视图,所述板在分隔成型件的两侧具有相同的流动引导结构。
具体实施方式
图1示出了根据本发明的叠板式热交换器2中的板1的视图。在相应的板1上,空腔3由板表面4和包围壁5区域地限定,所述包围壁5从板表面4突起并且在后者周围延伸。叠板式热交换器2具有若干一个叠放在另一个上的这样的板1,在两个板1之间形成有空腔3。具体地,叠板式热交换器2能够为用于机动车辆的油冷却器、制冷器或者冷凝器。
相应的板1被确定形状以便是细长的并且具有第一短侧6a和与第一短侧6a相对放置的第二短侧6b。两个短侧6a和6b通过两个相对的长侧7a和7b而彼此连接。短侧6a和6b与长侧7a和7b限定板表面4。在第一短侧6a,形成有两个流动开口8a和8b。第一介质M1能够流过流动开口8a和8b而进入到空腔3中和从空腔3流出。在第二短侧6b,布置有两个通道开口9a和9b,在所述两个通道开口9a和9b周围分别形成有从板表面4突出到空腔3中的圆顶10a和10b。圆顶10a和10b防止第二介质M2流入到空腔3中,和防止第一介质M1从空腔3流出。流动开口8a和8b以及通道开口9a和9b在叠板式热交换器2的一个放置在另一个上的板1中交替,使得在叠放的空腔3中分别流过第一介质M1或第二介质M2。
在板表面4上,形成有突出到空腔3中的细长的分隔成型件11,即,所谓的凸条,所述凸条从第一短侧6a沿第二短侧6b的方向在两个流动开口8a和8b之间延伸。在本文中,分隔成型件11以角度α邻接第一短侧6a,所述角度α优选位于45°与90°之间。在该示例实施例中,分隔成型件11为直线形,并且以60°的角度α邻接第一短侧6a。分隔成型件11以0.3至第一短侧6a的全长的比例分割第一短侧6a,并且从第一短侧6a沿第二短侧6b的方向延伸长侧7a和7b的长度的0.8倍。
分隔成型件11将板表面4分割为具有不相等的流动截面的两个流动区域4a和4b。从供应通道12a,第一介质M1流过第一流动开口8a而进入到第一流动区域4a,并且还沿第二短侧6b的方向流动。在第二短侧6b,第一介质M1被转移并且在第二流动区域4b中向流动开口8b流动并且进入到排出通道12b中。如在本文中并且进一步由箭头指示的,第一介质M1在板1中以U形方式流动,并且流动截面沿从流动开口8a向流动开口8b的方向减小。流动截面由此适于第一介质M1的聚集状态,所述第一介质在此从气体变为流体,如在冷凝器中。具体地,输出与压力比例能够由此在叠板式热交换器2中被优化,并且能够最优地利用热交换所需的第一介质M1的量。另外,流动开口8a和8b还具有彼此不同并且适于第一介质M1的聚集状态的流动截面。应当理解的是,板1中的流动截面与流动开口8a和8b的流动截面也能够适于第一介质M1,所述第一介质M1诸如例如在制冷器或蒸发器中从流体变为气体。
另外,在流动区域4a中布置有第一流动引导结构13a,并且在流动区域4b中布置有第二流动引导结构13b。在该示例实施例中,第一流动引导结构13a包括若干凸块(nub)14,所述凸块在流动区域4a中一体地形成(例如冲压)在板表面4上,并且突出到空腔3中。在该示例实施例中,第二流动引导结构13b以波状的方式形成,并且例如一体地冲压在板表面4上,并且方便地突出到空腔3中。流动结构13a和13b在板1处引导并混合第一介质M1,并且能够由此加强热交换。另外,分隔成型件11区域地形成在第二流动结构13b上,使得在分隔成型件11处防止了第一介质M1的不受阻碍的流过。
应当理解的是,用于第二介质M2的板能够以相同的方式被构造。然而,在本文所示的板1处,第二介质M2没有流动,并且如在本文中并进一步由箭头指示的,经由第一流过开口9a的供应通道15a以及第二流过开口9b的排出通道15b被运送到下一个板的空腔中。
图2示出了根据本发明的叠板式热交换器2中的替代地构造的板1的视图。在该示例实施例中,分隔成型件11具有以弯曲角β彼此相邻的两个直线形分隔区域11a和11b。弯曲角β在本文中大约为160°,并且较短的分隔区域11a的长度与分隔成型件11的总长度的比例大约处于0.3。因此,较长的分隔区域11b的长度与分隔成型件11的总长度的比例大约为0.7。在流动区域4a和4b中分别布置有流动引导结构13a和13b。第一流动引导结构13a包括若干凸块14,而第二流动引导结构13b以波状的方式被确定形状。在该示例实施例中,流动开口8a和8b的流动截面相同。
图3示出了根据本发明的叠板式热交换器2中的替代地构造的板1的视图。在该示例实施例中,分隔成型件11通过接近90°的角度α邻接第一短侧6a。在流动区域4a中,流动引导结构13a形成有若干凸块14,而在流动区域4b中形成有第二波状流动引导结构13b。
图4示出了根据本发明的叠板式热交换器2中的替代地构造的板1的视图。在流动区域4a中,流动引导结构13a以紊流***件16的形式布置,而在流动区域4b中,形成有第二波状流动引导结构13b。在该示例实施例中,分隔成型件11通过接近90°的角度α邻接第一短侧6a。
图5示出了根据本发明的叠板式热交换器2中的板1的视图。在本文中,两个波状流动引导结构13a和13b以相同的方式构造,并且在分隔成型件11处镜像对称地形成。分隔成型件11通过接近90°的角度α邻接第一短侧。
总之,在根据本发明的叠板式热交换器2中,各板1中的流动截面能够适于各流过的介质M1和M2的聚集状态。由此,能够优化叠板式热交换器2中的输出与压力比例,并且能够最优地利用热交换所需的各介质M1和M2的量。
