Description

一种用于封闭在壳体中的生热电子器件的冷却***
本申请是申请日为2015年12月8日、国际申请号为 PCT/US2015/064402、国家申请号为201580006852.4、发明名称为“一种变速驱动***以及一种用于封闭在壳体中的生热电子器件的冷却***”的发明专利申请的分案申请。
技术领域
本申请总体上涉及一种用于变速驱动装置的冷却歧管。本申请更具体涉及一种用于变速驱动装置(variable speed drive)的结构框架冷却歧管。
背景技术
容纳电力开关器件的电气面板产生大量热量，这些热量必须移除以使得电子部件不会由于温度过高而发生故障。在诸如电机控制中所使用的变速驱动装置的应用和暖通空调(HVAC)应用中，所使用的电气面板通常将软管用于分配冷却剂并将钢构件用于结构支撑。
发明内容
本公开内容公开了一种起到冷却流体歧管和结构构件作用的单个零件。软管可能发生故障和导致流体接触电气齿轮内的通电部件或总线，从而造成短路或设备停机。所公开的布置消除了软管的使用或将软管的使用减到最少并且提供与支撑电气柜和安装在柜内的电气部件的结构构件成为一体的冷却通道。
所公开的***和/或方法的预期优点满足这些需求中的一个或多个需求或者提供其他有利特征。从本说明书中将使其他特征和优点明显。
一个实施例涉及一种变速驱动装置，所述变速驱动装置包括连接至交流电源的转换器、连接至所述转换器的直流环节、以及连接至所述直流环节的逆变器，所述逆变器被配置为将来自直流环节的直流电压转换成具有所述可变电压和所述可变频率的输出交流电，所述逆变器进一步包括至少一个电力电子器件模块和相关联的控制电路；与所述电力电子器件模块热连通并且与歧管流体连通的不导电散热器，所述歧管包括中空管状构件、用于将冷却流体导入和导出所述管状构件的多个端口、用于将所述歧管附接至结构框架上的至少一个托架、和用于将所述至少一个电力电子器件模块附接至所述管状构件上的至少一个托架。在示例性实施例中，所述管状构件包括与至少一个水平构件部流体连通的至少一个竖直构件部。
另一个实施例涉及一种歧管，所述歧管包括具有流体连通的至少一个竖直构件部和至少一个水平构件部的中空管状构件、用于将冷却流体导入和导出所述歧管的多个端口、用于将所述歧管附接至结构框架上的至少一个托架、和用于将电力电子器件模块附接至所述歧管上的至少一个托架。
本文中所描述的实施例的某些优点包括用于包括歧管的VSD的结构框架。歧管可以由用于循环液体冷却剂的中空不锈钢管构成。歧管提供用于连接 VSD冷却区的分配端口。歧管通过将VSD内的软管减到最少从而降低了冷却流体在VSD内分配的复杂度。歧管还为VSD内的部件提供结构支撑。通过使流体冷却的VSD内的软管减到最少从而降低了冷却***设计的复杂度。任何非腐蚀性材料，例如非腐蚀性金属、陶瓷或聚合物材料，均可用于歧管管子，或者涂覆歧管管子，从而防止腐蚀。

具体实施方式
图1示出了用于典型商业设置的在建筑物12中的暖通空调***(HVAC ***)10的示例性环境。***10可以包括压缩机,所述压缩机可以合并到能够供应可以用于冷却建筑物12的冷冻液体的蒸汽压缩***14中。***10还可以包括锅炉16和配风***，所述锅炉16提供可以用于加热建筑物12的已加热液体，所述配风***使空气循环通过建筑物12。配风***可以包括回风管道 18、送风管道20和空气处理装置22。空气处理装置22可以包括热交换器，所述热交换器通过导管24连接至锅炉16和蒸汽压缩***14。取决于***10的运行模式，空气处理装置22中的热交换器可以从锅炉16接收已加热液体或从蒸汽压缩***14接收冷冻液体。***10示出了在建筑物12的每个楼层上的单独的空气处理装置，但将认识到楼层之间可以共享这些部件。
图2示意性展示了图1中的建筑物12中可以使用的、带有VSD 26的蒸汽压缩***14的示例性实施例。蒸汽压缩***14可以包括压缩机28、冷凝器 30、液体冷冻机或蒸发器32和控制面板34。通过由VSD 26供电的电机36驱动压缩机28。VSD 26从交流电源38接收具有具体的固定线电压和固定线频率的交流电并且向电机36提供处于所需电压和所需频率的交流电，电压和频率都可以改变以满足具体的要求。控制面板34可以包括各种不同的部件，诸如模数(A/D)转换器、微处理器、非瞬态存储器、和接口板，以控制蒸汽压缩***14的运行。控制面板34还可以用于控制VSD 26和电机36的运行。
压缩机28压缩制冷剂蒸汽并且通过排放管路将蒸汽输送至冷凝器30。压缩机28可以是任何合适类型的压缩机，例如，螺杆式压缩机、离心式压缩机、往复式压缩机、涡旋压缩机等。压缩机28输送至冷凝器30的制冷剂蒸汽与流体(例如，空气或水)形成热交换关系，并且由于与流体的热交换关系而经历相变成为制冷剂液体。来自冷凝器30的冷凝液体制冷剂流过膨胀装置 (未示出)到达蒸发器32。
蒸发器32可以包括冷却负载的供给管路与回流管路的连接。工艺流体(例如，水、乙二醇、氯化钙卤水或氯化钠卤水)经由回流管路行进到蒸发器 32中并且经由供给管路离开蒸发器32。蒸发器32中的液体制冷剂与工艺流体形成热交换关系从而降低工艺流体的温度。由于与工艺流体的热交换关系，蒸发器32中的制冷剂液体经历相变成为制冷剂蒸汽。蒸发器32中的蒸汽制冷剂离开蒸发器32并且通过抽吸管路返回到压缩机28从而完成循环。
图3示出了具有多个位于冷却构件42之上(over)的开关40的变速驱动装置26的一部分。针对不同的应用或HVAC***，VSD 26可以用于向电机提供所需电力。例如，这种电机可以驱动蒸汽压缩***的压缩机。VSD 26的开关40被描绘成带有3个双IGBT的英飞凌模块，但可以使用冷却构件42冷却需要冷却的其他半导体装置或其他电子部件。管道43、45连接至入口通道47 和出口通道49，以分别将冷却流体引入冷却构件42和将冷却流体移出冷却构件42。管道43和45或其他合适的流动通道连接至冷却***，该冷却***提供连续流动的冷却流体至冷却构件42。冷却流体应用于管道43，流经冷却构件 42，并且通过管道45流出。
各种不同的冷却流体(包括冷凝水、水、和已知制冷剂)可以在冷却构件 42内循环并且用于冷却电子部件。此外，各种不同的冷却***可以用于冷却流出冷却构件42的冷却流体。
冷却构件42冷却被用于为HVAC***的电机提供电力的VSD 26中的模块。这些模块可以以密封关系连接至冷却构件42。应用于冷却构件42的冷却流体可以是流经封闭环路中的冷却构件42和热交换器的水。热交换器在水被再次引入冷却构件42之前对水进行冷却。热交换器可以是管壳式热交换器，并且来自HVAC***的冷却塔的水可以用于冷却应用于冷却构件42的水。
图4示出了有待安装到VSD 26的部件上的多个冷却构件42。冷却构件42 竖直定位并且安装在部件74的侧部(例如，直流环节电容器)。在另一个实施例中，部件74可以被定向为朝着任何合适的方向，如竖直、水平、或对角取向。
接下来参照图5和图6，示出了封闭在VSD 26中的内部部件的示例性视图的立面图。歧管50安装在VSD 26的框架52内。歧管50包括呈90°角连接的水平管状构件54和竖直管状构件56，水平管状构件54和竖直管状构件56流体连通，以便冷却流体流动到供给联接器或端口58。供给端口58通过管道43与冷却构件42的入口通道47以流式连通方式连接，从而向安装在开关 40上的冷却构件42提供冷却流体。在冷却流体循环通过冷却构件42之后，冷却流体通过出口通道49离开冷却构件42并且流入回流导管62，并且从与回流导管62流体连通的排放端口64离开VSD 26。至少一个供给端口58被指定为连接至来源(未示出)的入口端口，用于将冷却流体接收进入歧管50。
参照图7至图9，示出了示例性歧管50。多个端口58沿着水平管状构件 54和竖直管状构件56定位。端口58的数量和位置可以根据应用(例如，开关 40的数量及其在框架52内的位置)而变化。角托架66沿着水平管状构件54 设置以便附接开关40。端托架68位于水平管状构件54和竖直管状构件56的远端，以便分别在端面板72和底座76附接至框架52。辅助角托架70也可以在邻近竖直管状构件56与水平管状构件54相交处附接至歧管50，从而将歧管 50连接至内部框架构件78。
歧管50向框架52和开关40提供结构支撑，同时将同一空间用作冷却流体的导管。双用途歧管在VSD 26内提供附加有用的空间并且减少将冷却构件 42与冷却流体来源连接所需的软管量。
应理解到，本申请不局限于以下说明中所阐述的或图中所展示的细节或方法。还应理解到，本文中所采用的措辞和术语仅仅是为了说明目的，而不应视为限制性的。
虽然图中所示的和本文中所描述的示例性实施例目前是优选的，但应理解的是，这些实施例仅是通过示例方式提供的。任何过程或方法步骤的顺序或次序可以根据替代性实施例被改变或被重新排序。
重要的是应注意各种示例性实施例中所示的变速驱动装置的构造和布置仅是说明性的。尽管本公开中已经详细描述了仅几个实施例，但审查本公开的人员将容易认识到在实质上不脱离权利要求书中所引用的主题的新颖性教导和优点的情况下可以进行许多修改(例如，各种元件的大小的变化、尺寸的变化、结构的变化、不同元件的形状和比例的变化、参数值的变化、安装布置的变化、材料使用的变化、颜色的变化、取向的变化等)。例如，示出为一体形成的元件可以由多个零件或元件构造而成，元件的位置可以颠倒或以其他方式变化，并且分立元件的性质或数量或位置可以更改或变化。相应地，所有这类修改都旨在被包括在本申请的范围内。任何过程或方法步骤的顺序或次序可以根据替代性实施例而不同或被重新排序。在权利要求书中，任何“方法加功能”的条款表述意欲涵盖本文中所描述的执行所引用的功能的结构，并且不仅涵盖结构等同物，而且还涵盖等同结构。在不脱离本申请的范围的情况下，可以对示例性实施例的设计、操作条件和布置进行其他替代、修改、改变和省略。
