Description

热交换器布置
本申请涉及热交换器布置,尤其是涉及在制冷回路中例如在加热、通风、空气调节和制冷(HVAC/R)系统中使用的热交换器布置。
背景技术
在制冷回路中,热交换器用于在循环制冷剂和环境之间传热。
提供供应有效的热交换、容易安装且具有长使用期限的热交换器布置将是有益的。
发明内容
根据本发明的示例性实施方案的热交换器布置包括至少一个热交换器和支撑结构。至少一个热交换器具有形成热交换器的上侧的至少一个基本上水平地定向的歧管,至少一个歧管具有横向端部。支撑结构具有至少部分地包括金属材料的主要部分和与至少一个歧管的相应横向端部相联的歧管支撑部分。歧管支撑部分至少部分地由非金属材料制成并配置成接收至少一个歧管的横向端部,用于阻止至少一个歧管与支撑结构的任何金属部分接触。
在根据本发明的示例性实施方案的热交换器布置中,在至少一个热交换器的金属部分和支撑结构的金属部分之间没有金属到金属接触。这避免了由可能在两个(不同)金属的界面处出现的电化学效应引起的腐蚀。
在根据本发明的示例性实施方案的热交换器布置中,热交换器特别是借助于歧管支撑部分从支撑结构悬挂。假定在这个配置中没有对从下面支撑热交换器的需要,则在支撑结构内的热交换器的安装变得容易。它进一步便于在热交换器之下的区域中收集并排出在热交换器的表面上产生的冷凝液。
在根据本发明的示例性实施方案的热交换器布置中,在热交换器和支撑结构之间的接触点的数量减小了。这也减小水可聚积/停滞于其中的且因此水需要从其中排出以便避免腐蚀的区域的数量。
本发明的示例性实施方案还提供在热交换器和支撑结构之间的机械去耦,导致振动的有效减弱。它们进一步允许补偿热交换器线圈的热膨胀和变形。
下面,将参考附图详细描述根据本发明的示例性实施方案的热交换器布置。
附图说明
图1示出根据本发明的示例性实施方案的热交换器布置的透视图。
图2示出图1所示的热交换器布置的横向截面图。
图3示出图1和2所示的热交换器布置的区域的放大截面图,其中热交换器布置在支撑结构上。
图4a到4f是示出当热交换器部署在根据本发明的示例性实施方案的热交换器布置中时的热交换器的不同形状的示意性侧视图。
具体实施方式
图1示出根据本发明的示例性实施方案的热交换器布置2的透视图,以及图2示出其横向截面图。
热交换器布置2包括由框架提供的支撑结构10,框架由四个立柱12和两个水平梁18组成,每个水平梁18连接相邻立柱12的上端。
支撑结构10还包括斜增强撑条20。每个斜增强撑条20连接立柱12与水平梁18,用于增强支撑结构10的刚度。
图1和2所示的热交换器布置2的示例性实施方案包括由支撑结构10支撑的、如由虚线M指示地对称布置的两个V形热交换器4,。将参考图4c和4d在下面进一步更详细地讨论热交换器4的V形状。
如可在附图1中看到的,热交换器布置可包括由支撑结构10支撑的盖板26。在图1中示出覆盖热交换器布置2的右侧的一个盖板26。为了允许在热交换器布置2的内部内的无障碍视野,在图1中没有描绘可被提供来覆盖热交换器布置2的左侧的第二盖板26。盖板26设置有具有在形状上是圆形的开口28,用于容纳用于产生通过热交换器4的空气流的风扇。在图1中只示出电动机24,但不是风扇的推进器。
热交换器4的上端分别设置有歧管6a、6b。图2的投影平面定向成垂直于图1所示的轴A,即歧管6a、6b垂直于图2的投影平面而延伸。
歧管6a、6b流体地连接到热交换器4的管22。热交换器4的管22在图1和2中是不可见的,但在图3中是可见的。歧管6a、6b被配置成分别将制冷剂供应到所述管22并从所述管22收集制冷剂。
所述歧管6a、6b还被配置成连接热交换器4与支撑结构10。这参考图3在下面更详细地被描述。
图3示出热交换器4之一例如在图2所示的结构的右上角处与支撑结构10连接的区域的放大横截面侧视图。由图2中的线P描绘的图3的投影平面被定向成垂直于图2的投影平面。
热交换器4包括多个管22,其中三个在图3中描绘出。管22可以是多口管22和/或设置有用于增强热交换的鳍片的管22。管22在第一歧管6a和第二歧管6b之间延伸。在图3中没有示出第二歧管6b。管22与所述歧管6a、6b流体地连接,允许歧管6a、6b将制冷剂输送到所述管22并从所述管22收集制冷剂。
歧管6a、6b特别是由在热交换器4的横向边缘之外延伸的中空管提供,从而形成从热交换器4的横向边缘突出的横向端部8。中空管由适当的密封件30例如插塞或盖紧密地密封在两端处。
虽然在图3中只示出热交换器4/歧管6的右侧,技术人员将理解,左侧相应地被形成。
支撑结构10包括被配置成容纳从热交换器4的横向边缘突出的歧管6a、6b的横向端部8的歧管支撑部分14,其中只有一个在图3中示出。
在图3所示的示例性实施方案中,歧管支撑部分14包括从支撑结构10的柱12的内侧朝着热交换器4突出的突出部15。在未在附图中示出的可选的实施方案中,歧管支撑部分14可由适当地形成的管段提供,管段被配置成容纳歧管6a的横向端部8。
歧管支撑部分14还包括连接元件16,其围绕歧管6a的相应横向端部8并连接相应的横向端部8与突出部15或管段(未示出)。
连接元件16由非金属材料例如塑胶或橡胶材料制成。这避免在通常由金属制成的歧管6a和通常也由金属制成的歧管支撑部分14之间的任何直接接触。
连接元件16特别是可由弹性材料制成,以便提供在热交换器4和支撑结构10之间的弹性减弱,例如以去耦在热交换器4和支撑结构10之间的振动。
在未在附图中示出的可选的实施方案中,可使用非金属和/或弹性材料例如塑胶或橡胶来形成歧管支撑部分14本身的突出部15。在这样的实施方案中,没有非金属连接元件16对防止在歧管6a和突出部15之间的直接金属到金属接触是必需的。
突出部15和/或连接元件16被形成,使得在热交换器4和支撑结构10之间没有直接或中间接触。替代地,热交换器4仅通过歧管6a、6b的横向端部8并经由(可选的)连接元件16附着到歧管支撑部分14。
这样的悬挂配置防止在金属热交换器4和金属支撑结构10之间的任何直接金属到金属接触,且没有额外支撑热交换器4的需要。热交换器4特别是不需要从下面被支撑。
因为没有对从下面支撑热交换器4的需要,在热交换器4下面的区域中的在热交换器4的表面上产生的冷凝液的收集和排出变得容易。
这样的配置还提供在热交换器4和支撑结构10之间的机械去耦。这导致振动的有效减弱。它进一步允许补偿热交换器线圈22的热膨胀和变形。
图4a到4f是示出当热交换器可部署在根据本发明的示例性实施方案的热交换器2布置中时的热交换器4的不同形状的例子的示意性侧视图。为了实现有效的热交换,热交换器4的形状、特别是几何形状、角度和尺寸设计成优化沿着热交换器4的表面流动的空气的几乎均匀的分布。技术人员将理解,在图4a到4f中所示的例子不是详尽的,以及具有其它形状的热交换器4也可以被使用。
图4a到4f中所示的每个热交换器4包括平行于彼此布置在垂直于图4a到4f的投影平面而延伸的平面中的多个管22。因此,只有多个管22中的第一个(最前面的)管在图4a到4f的每个中是可见的。
图4a示出热交换器4的形状,其中热交换器4的多个管22具有I形状,其当在侧视图中看时从第一(上)歧管6a垂直地延伸到第二(下)歧管6b。
这样的I形热交换器4也可以相对于垂直线被定向在倾斜定向中,如它在图4b中描绘的。
图4c描绘具有V形状的热交换器4,如它在图1和2所示的热交换器组件2中使用的。图4c所示的热交换器4特别是包括沿着垂直平面从第一歧管6a向下延伸的第一部分4a和相对于所述垂直平面倾斜的第二部分4b。第二部分4b可相对于垂直平面以30°到60°的角度、特别地在40°和50°之间的角度倾斜。第二歧管6b布置在第二部分4b的上端处。第一和第二部分4a、4b在它们的相应下端处流体地连接到彼此,允许制冷剂在两个部分4a、4b之间转移。
图4d描绘可选的V形热交换器4,其设计成对垂直延伸的对称平面S是对称的。
图4e描绘具有U形状的热交换器4,U形状包括分别从上歧管6a、6b向下延伸的两个基本上垂直的部分4a、4b和流体地连接两个垂直部分4a、4b的下端的弓形连接部分4c。
在图4e所示的实施方案中,连接到热交换器4的垂直部分4a、4b的上端的两个歧管6a、6b布置在同一高度处。然而这仅仅是示例性的。通常,歧管6a、6b/热交换器4的垂直部分4a、4b的上端也可布置在不同的高度处。
图4f示出另一例子,其中省略第二垂直部分4b,且第二歧管6b直接附着到与第一垂直部分4a相对的弓形部分的上端。
在未在附图中示出的另外的实施方案中,弓形部分4c可进一步延伸到不同的高度,和/或倾斜部分4b,如它在图4c中所示的,可连接到与第一部分4a相对的弓形部分4c的端部。

在至少一个歧管包括至少一个分隔壁的配置中,热交换器4的入口和出口可设置在至少一个分隔壁的相对侧上的两个歧管6a、6b中的同一个处。可选地,入口可设置在歧管6a、6b中的第一个处,而出口设置在歧管6b、6a中的第二个处。
另外的实施方案
下面阐述很多可选的特征。这些特征可在特定的实施方案中单独地或与其它特征中的任一个组合地实现。

在另一实施方案中,热交换器和支撑结构仅经由至少一个歧管的横向端部来连接,且否则保持间隔开,即没有直接接触产生。这可靠地防止由电化学效应引起或增强的腐蚀。
在另一实施方案中,支撑结构可包括多个、特别是四个立柱和多个、特别是四个水平梁以连接立柱的相邻端部。这样的配置以低成本提供具有高刚度的支撑结构。
在另一实施方案中,支撑结构可此外包括斜增强撑条,每个斜增强撑条连接立柱与水平梁。提供这样的增强撑条甚至更进一步提高了支撑结构的刚度。
在另一实施方案中,热交换器可包括第一和第二歧管和在第一和第二歧管之间延伸并与第一和第二歧管流体地连接的多个管,特别是多口管和/或设置有鳍片的管。在这样的配置中,歧管分别允许制冷剂有效地分配到多个管并从多个管有效地收集制冷剂。
在另一实施方案中,第一和第二歧管以及多个管当在垂直横截面中看时可具有I形状。第一歧管可形成上歧管而第二歧管可形成下歧管。上歧管的横向端部可与位于支撑结构的相对柱的内侧的上端部处的支撑结构的相应歧管支撑部分连接。多个管可以特别是在基本上垂直的方向上延伸。这样的配置提供容易安装且可以在低成本下生产的简单热交换器。
在另一实施方案中,第一和第二歧管以及多个管当在垂直横截面中看时可具有V形状或U形状。第一歧管可提供布置在热交换器的左上端处的左上歧管,而第二歧管可提供布置在热交换器的右上端处的右上歧管。左上歧管的横向端部可与位于支撑结构的相对柱或梁的内侧的上端部处的支撑结构的相应歧管支撑部分连接;以及右上歧管的横向端部可与位于支撑结构的相对柱或梁的内侧的上端部处的支撑结构的相应歧管支撑部分连接。
包括具有V形状或U形状的管的热交换器提供大的传热表面,其允许非常有效的传热。借助于左上歧管和右上歧管安装这样的热交换器允许容易的安装和热交换器与支撑结构的可靠连接。
在另一实施方案中,具有V形状的多个管可包括第一基本上垂直的部分和相对于第一部分倾斜的第二部分。第一和第二部分可流体地连接在它们的相应下端处。第二倾斜部分特别是可相对于第一部分以30°到60°、特别地在40°和50°之间的角度、更特别地以45°的角度被定向。这样的配置允许可用空间的有效使用,可用空间用于在给定条件下提供尽可能大的传热表面。
在另一实施方案中,具有U形状的多个管可包括第一和第二基本上垂直的部分,其由适当地修圆/成弓形的连接部分流体地连接在它们的下端处,使得第一和第二基本上垂直的部分基本上平行于彼此。这样的配置允许可用空间的有效使用,以便提供尽可能大的传热表面。
在另一实施方案中,多个管当在垂直横截面中看时可具有J形状。在这个实施方案中,第一歧管形成上歧管而第二歧管形成下歧管。上歧管的横向端部与位于支撑结构的相对柱的内侧的上端部处的支撑结构的相应歧管支撑部分连接,而下歧管的横向端部与位于支撑结构的相对柱的内侧的中间部分处的支撑结构的相应歧管支撑部分连接。多个管特别是可包括第一基本上垂直的部分和流体地连接到第一部分的下端的第二修圆部分。
在另一实施方案中,热交换器布置可包括悬挂在公共支撑结构中的至少两个热交换器。热交换器布置特别是可包括两个V形热交换器,其布置成使得它们的倾斜段面向彼此。可选地,热交换器布置可包括两个J形热交换器,其布置成使得它们的修圆段面向彼此。这样的配置允许可用空间的非常有效的使用。
在另一实施方案中,歧管之一可包括入口和出口,歧管的内壁细分与入口相联的第一空间和与出口相联的第二空间。这允许逆流配置,其中制冷剂穿过多个管的第一部分在第一方向上穿过热交换器以及穿过多个管的第二部分在第二相反的方向上穿过热交换器流动。这样的配置可提高传热的效率。提供在同一歧管处的入口和出口可便于热交换器的安装;特别是,较少的管道可能是必要的。
在另一实施方案中,热交换器布置还可包括布置在支撑结构处或上的至少一个风扇。至少一个风扇特别是可水平地布置在支撑结构的相对水平梁之间。更特别地,它可位于V形热交换器的倾斜部分之上或J形或U形热交换器的修圆部分之上,以便通过穿过和/或沿着热交换器的表面吹空气来增强热交换。
在另一实施方案中,至少一个歧管和/或管至少部分地由金属、特别是铝或铝合金制成。铝是轻金属并具有高导热率。因此,它允许提供有效的然而重量轻的热交换器。
虽然参考示例性实施方案描述了本发明,但本领域技术人员将理解,可做出各种变化且等效形式可代替其元件而不偏离本发明的范围。此外,可做出很多修改以对本发明的教导采用特定情况或材料而不偏离其本质范围。因此,意图是本发明不限于所公开的特定实施方案,但本公开包括落在所附权利要求的范围内的所有实施方案。
