技术领域
 本发明一般来说涉及制冷单元和气体冷却器/冷凝器热交换器，并且更具体来说，涉及改进运输制冷单元的气体冷却器/冷凝器热交换器的冷凝物排放和耐腐蚀性。
背景技术
通常在如卡车、拖车、集装箱或联运集装箱的隔热货箱等封闭空间内的受控环境中运输易腐物品。与所述货箱内的封闭空间操作上相关联地使用制冷系统(还称为运输制冷单元)，以用于将所述封闭空间内的空气的温度控制在针对所述货箱内装载的具体类型的易腐物品所选择的所需温度范围内。制冷单元被安装至货箱的壁上，典型地安装至货箱的前部端上，与货箱的门相对，所述门典型地位于货箱的后部处。
制冷单元包括安置在货箱外部的制冷剂压缩机和冷凝器以及安置在货箱的封闭空间内的蒸发器，所述压缩机、冷凝器和蒸发器以串联制冷剂流动关系连接在制冷剂回路中。当制冷系统正在操作时，从封闭空间内抽出待冷却的空气，使其与通过蒸发器的热交换管的制冷剂蒸汽成热交换关系来通过蒸发器，然后将其供应回至所述封闭空间。已经穿过蒸发器的制冷剂蒸汽在压缩机中被压缩成高温高压蒸汽并且然后通过冷凝器，所述冷凝器用作制冷剂排热热交换器，其中通过的高温制冷剂蒸汽与冷却空气(典型地，环境空气)或水/乙二醇溶液成热交换关系。
在常规的现有技术运输制冷单元中，冷凝器包括具有穿过一组隔开的板翅片的圆管阵列的标准圆管板翅式(RTPF)热交换器。典型地，多个圆管被插入穿过所述翅片组的板中的孔，以便纵向地延伸穿过所述翅片组的板和安置在所述翅片组的相对端处的一对管板。穿过所述管板的圆管的端部通过管弯头或回弯头连接以便形成一个或多个通过热交换器的制冷剂流动回路。当安装在制冷剂单元中时，所述冷凝器热交换器布置有在大体水平方向上纵向延伸的圆管并且所述翅片板在大体垂直平面中延伸。所述翅片板一般是平板或波面板，并且可以包括百叶窗或其它翅片增强件以便改进空气侧热传递性能。
如在现有技术中在所述冷凝器热交换器在水平位置中延伸的情况下，需要大量空间。所述热交换器旋管的水平布置确保沉积在所述翅片的表面上的任何冷凝物由于所述板翅片的垂直定向而自然地离开翅片。所希望的是避免冷凝物积聚在翅片表面上，因为水是一种电解质，它在翅片表面上的存在会导致腐蚀加速。因此，期望一种较紧凑的冷凝器热交换器旋管设计，所述设计促进充分水排放并且提供可接受的耐腐蚀性。
发明内容
提供一种运输制冷单元，其具有促进充分水排放和耐腐蚀性的制冷剂排热热交换器(冷凝器/气体冷却器)。所述制冷剂排热热交换器包括沿相关联的冷凝器/气体冷却器风机的周边延伸的环绕翅管式旋管。所述环绕翅管式旋管具有多个热交换管环路和安装至所述多个热交换管环路的多个板翅片。每个热交换管环路由通过回弯头连接的多个线性管区段或多个发夹管形成，其中每个线性管区段以相对于垂直的至少20度的倾斜角纵向地延伸。在一个实施方案中，每个线性管区段以在从至少20度至90度的范围内的倾斜角纵向地延伸。每个热交换环路可具有大体正方形构造、大体菱形样构造、大体六边形样构造或无任何显著长度的垂直延伸管区段的其它构造。所述翅片可以是平板翅片或波面板翅片，有或没有另外的空气侧热传递增强件，如百叶窗、偏置管等等。

具体实施方式
首先参见图的图1，绘示冷藏货物集装箱(大体上以10来参考)的一个示例性实施方案。货物集装箱10具有由前部壁或前壁12、后部壁或后壁14、一对相对的侧壁13和15、顶板16以及底板18形成的隔热箱形结构。所述箱形结构界定货物空间11，在所述空间中被运输的货物100的箱子、纸盒或货盘堆在底板18上。后壁14设置有一个或多个门(未图示)，通过这些门可以进入所述货物空间以用于将货物18装载到集装箱10中。当所述门被关闭时，在集装箱10内建立大致气密的密封货物空间，这样防止内部空气逃逸出货物空间11。
制冷单元20被安装至集装箱10的壁上。一般来说，制冷单元20被接纳在集装箱10的前部壁12中的开口中并且围绕它的周长安装至集装箱10的前部壁12上，例如如在图1中所绘示，用于调节冷藏室11 (即，集装箱10的货物空间)内的空气。现在还参见图2和图3，制冷单元20包括与货物空间11隔离的具有相关联的压缩机驱动电动机的压缩机22和冷凝器/气体冷却器模块24，以及与在集装箱10内界定的货物空间11操作上相关联的蒸发器模块。所述蒸发器模块包括安置在与货箱11的内部体积成空气流动连通的制冷单元的上部内的一对蒸发器风机26和具有多个制冷剂输送管的蒸发器热交换器(未图示)，流动通过制冷单元20的制冷回路的制冷剂蒸汽以与待冷却的空气成热交换关系通过所述管，其中由蒸发器风机26从货物空间11内抽出所述待冷却的空气，使其经过所述蒸发器热交换器表面并且供应回至所述货物空间。
冷凝器/气体冷却器模块24包括冷凝器风机28和在货物空间11的外部安装在制冷单元20的前部区域中的制冷剂排热热交换器30。制冷剂排热热交换器30可用作冷凝器或用作气体冷却器。在其中所述制冷剂排热热交换器是以亚临界循环操作的制冷剂蒸汽压缩系统的部件的制冷单元中，所述制冷剂排热热交换器用作冷凝器，也就是将从其中通过的高温高压制冷剂蒸汽冷凝至高压低温制冷剂液体。在其中所述制冷剂排热热交换器是以跨临界循环操作的制冷剂蒸汽压缩系统的部件的制冷单元中，所述制冷剂排热热交换器仅用作气体冷却器，也就是将从其中通过的高温高压制冷剂蒸汽冷却而不是冷凝至高压低温制冷剂蒸汽。
制冷剂排热热交换器30包括环绕冷凝器风机28的翅管式热交换器。举例来说，如图3至图5中所示，热交换器30的管不是在水平方向上纵向地延伸，而是在风机28的叶片的尖端的径向外侧围绕冷凝器/气体冷却器风机28的周边延伸，所述风机安置在制冷排热热交换器30的前平面处。环绕翅管式旋管32具有多个热交换管环路34和安装至所述多个热交换管环路34上的多个板翅片40。翅片40可以是平板翅片或波面板翅片，如图5中所绘示，有或没有另外的空气侧热传递增强件，如百叶窗、偏置管、波纹等等。
环绕翅管式旋管32可具有任何几个管排，典型地从两个至十二个，其中每排具有至少一个管环路34，典型地两个至四个。在图3至图5中绘示的实施方案中，环绕翅管式热交换器32具有五个管排，其中每排具有三个热交换管环路34。在操作中，冷凝器风机28将环境室外空气抽吸通过位于前面板21后面的制冷剂排热热交换器30 (进入的空气在箭头方向上流动)并且将所述空气通过围绕冷凝器/气体冷却器风机28的制冷单元20的前面板21的开口23排放回至室外环境中。应当指出的是，风机28相对于冷凝器/气体冷却器30的位置并不是对本发明的限制。可以采用将风机28定位在所述冷凝器/气体冷却器的上游或下游的两种构造，然而，后一种布置是热力学上较有效的。
现在特别参见图6至图8，每个热交换管环路34由通过回弯头38连接的多个线性管区段或发夹36形成。每个热交换管环路34可由在一对管板42与44之间延伸的连续热交换管40形成。如在常规实践中，穿过每个管板42和44的热交换管40的端部可通过U形弯头(未图示)互连以便根据需要来形成一个或多个制冷剂流动回路，这些回路以本领域技术人员熟知的方式通过热交换器30。
为了形成每个热交换管环路34，热交换管40被适当地弯曲以便界定所希望的形状。举例来说，热交换管环路34可采取平行四边形的形状，如图6中绘示的示例性实施方案中所示，热交换管环路34是通过弯曲热交换管40以便界定在管板42与44之间延伸的大体正方形(具有相等夹角的菱形)形状来形成。热交换管环路34还可以界定其它形状，例如如在图7中绘示的示例性实施方案中，其中热交换管环路34是通过弯曲热交换管40以便界定在管板42与44之间延伸的大体六边形形状来形成。热交换管环路34还可以形成为具有例如如图9中所示的大体环形构造或如图10中所示的大体椭圆形构造的非线性管环路。
当冷凝器/气体冷却器模块24安装在制冷单元20中时，制冷剂排热热交换器30布置有围绕冷凝器/气体冷却器风机28的周边安置的环绕翅管式热交换器旋管32，以使得每个热交换环路34的每个线性管区段36以相对于垂直V的至少20度的倾斜角θ纵向地延伸。在一个实施方案中，每个线性管区段以在从至少20度直至并且包括90度的范围内的倾斜角纵向地延伸，这表示水平延伸的管区段。如图8中所示，其中图3至图6的翅管式热交换器旋管32的热交换管环路34的单个管，其中出于说明目的而省去翅片，倾斜角θ被测量为线性管区段36的纵向轴线与垂直轴线V之间的内夹角。
通过确保热交换管环路34的所有线性区段36以与垂直位置的至少20度的倾斜纵向地延伸，由于雨水或由于来自在高湿度条件下通过所述制冷剂排热热交换器的空气中的湿气的冷凝物引起的在板翅片40的表面上收集的水的充分排放得以保证，因为板翅片40与热交换管环路34的线性区段36的纵向轴线正交地延伸。水的积极排放得以确保，即使在波面板翅片的情况下，其中水往往会收集在所述波面板翅片的凹部中。
假如与本公开的教义相反地，热交换管环路34的线性区段36大体垂直地延伸，那么板翅片40将大体水平地延伸，这样决不会促进来自所述内表面的水的排放，并且在波面板翅片的情况下，允许水积聚在所述波面板翅片的凹部中。随着时间推移，由于积聚在所述板翅片的表面上的水用作起始和加速腐蚀过程的电解质，所以所述板翅片的耐腐蚀性将显著地缩短。
本文所使用的术语是出于描述而非限制的目的。本文所公开的特定结构和功能细节不应被解释为是限制性的，而是仅仅作为教导本领域技术人员采用本发明的基础。本领域技术人员还将认识到可替代参照本文所公开的示例性实施方案所描述的元件而不脱离本发明范围的等效物。此外，本发明还可同样地应用于制冷系统、空调系统以及热泵系统。
此外，排热热交换器构造可包括一个以上排热热交换器。举例来说，冷凝器/气体冷却器和中间冷却器以及冷凝器/气体冷却器和散热器可集成在单个模块中并且同时形成(弯曲)。前者构造可在高效率系统中使用，并且后者设计可在由发动机驱动的HVAC&R系统中应用。
虽然本发明已参照如在所述图中所示的示例性实施方案进行了具体展示和描述，但本领域技术人员将会认识到，可在不脱离本发明的精神和范围的情况下做出各种修改。举例来说，虽然环绕翅管式热交换器32在本文中被描述为具有圆形热交换管，但应理解的是所述热交换管可改为非圆形管，如大体矩形或椭圆形横截面的多通道扁平管。因此，本公开意图并不限于所公开的一个或多个特定实施方案，而是本公开将包括落在所附权利要求的范围内的所有实施方案。
