Description

径流式通风机
技术领域
本发明涉及一种被设计为紧凑型高转速径流式通风机的径流式通风机。
背景技术
创新型径流式通风机在现有技术中是已知的，例如由德国实用新型DE202018106694U1揭示。
相应的径流式通风机包括数个用于容置马达并形成从入口经压力室到出口的流径的壳体部件。与此同时，流体应尽可能最佳地从入口被输送至出口。良好的流动条件能够改善效率、压力形成和径流式风扇的声响。径流式通风机一般具有螺旋状壳体，该壳体接收并制动径向叶轮所输出的快速流，最终将其转化为有用压力。其中，无冲击延迟对压力形成是有利的。
发明内容
本发明的目的是提供一种径流式通风机，这种径流式通风机结构紧凑，部件数少，并且在声响改善的同时具有高效率。
这个目的通过根据权利要求1所述的特征组合而达成。
根据本发明，提出一种径流式通风机，具有基本部件、套设在基本部件上的带有出口的壳体部件、马达电子组件和内转子电动马达，内转子电动马达通过轴体驱动通风机叶轮。马达电子组件和电动马达的定子在基本部件中被封装件封装起来并且共同形成整体一件式构造单元。该径流式通风机还具有呈螺旋状围绕通风机叶轮变大的压力室，该压力室由壳体部件和封装件形成和限定。
例如使用环氧基热固性塑料作为封装件并进行注塑处理。封装件形成基本部件的用于容置马达电子组件和定子的结构，其中，为此而在封装件中设置相应的空腔。此外，用于电性连接径流式通风机的插接装置如连接插头或插头壳体也可以整合在封装件中并且特别是形成于基本部件外侧。
配合壳体部件利用封装件的一体式设计，以提供压力室的螺旋形几何形状。不需要附加部件。
在所述径流式通风机的一个有利实施中，如下设置：封装件包括沿轴向朝壳体部件延伸的突出的环形区段，该环形区段的轴向端面限定压力室。此外，环形区段相对于基本部件的其余区域突出，从而为马达电子组件提供与压力室介质分离的容置空间，也就是包围马达电子部件。几何上这样来确定环形区段的轴向延伸和轴向端面，以便形成压力室的螺旋形状。其中，优选如下设置：通过轴向扩展和径向扩展产生螺旋形压力室。通过轴向端面的宽度实现径向扩展，通过环形区段的轴向高度实现轴向扩展。
在进一步方案中，所述径流式通风机的特征进一步在于：壳体部件具有限定压力室的恒定直径，并且压力室的螺旋形状仅由封装件或者说突出的环形区段限定。在这个实施中，径流式通风机的构造空间特别紧凑。
以下实施也是有利的：电动马达布置在马达电子组件的第一轴向侧，并且压力室布置在马达电子组件的与第一轴向侧相对的第二轴向侧。这就可以借助穿过压力室的邻近流体来冷却马达电子组件。与此同时，马达组和流体被沿轴向布置在二者之间的马达电子组件隔开。
优选地，马达电子组件布置在印制电路板上，并且印制电路板同样被封装件完全包围。直接通过封装件将印制电路板和马达电子组件或者说布置在印制电路板上的马达电子部件紧固在基本部件中。
在进一步方案中，所述径流式通风机的特征进一步在于：基本部件在用于轴体的旋转轴周围具有圆柱形空隙，电动马达的固定在轴体上的转子插入该空隙中。圆柱形空隙模仿的是密封式马达(Spalttopfmotor)的密封罐(Spalttopf)。定子在封装件中沿径向邻接空隙定位，固定在轴体上的转子在插入空隙的情况下与定子共同作用，并且实现密封式马达结构。
空隙具有由封装件形成的封闭底部。如此一来，马达完全封装在基本部件中。
所述径流式通风机的一个改进方案进一步提出：包围通风机叶轮的环形分流件被布置成沿径向邻接通风机叶轮，该分流件与壳体部件一起在通风机叶轮周围形成扩散件，扩散件直接与压力室衔接。
对通风机叶轮重要的是，通风机叶轮在出口处整周具有均匀背压。如此一来，通风机叶轮的每个叶片都将对流动做出最佳贡献。通风机叶轮周围不均匀的压力分布会造成不利且不期望的流动中断并导致流体回流到通风机叶轮中。为了实现从通风机叶轮到压力室中的有利的压力形成，在通风机叶轮周围设置分流件，该分流件与通风机壳体一起为通风机叶轮所排出的流体提供扩散件，该扩散件与压力室处于直接通流连接并且为通风机叶轮提供均匀背压。径向排出的空气沿径向由内向外穿过扩散件，直至到达扩散件的径向末端，而后进入压力室中。
压力室的入口自然是径向邻接扩散件，但螺旋形压力室本身则优选是轴向邻接扩散件地形成在相邻的轴向平面中，使得流体从分流件沿切向流入压力室中。分流件可以沿径向向外延伸，使得流入
Figure BDA0003015921390000031
是发生在壳体部件的径向外侧区域和壳体部件的螺旋形压力室中，并且在此期间产生明确的螺旋涡流(Korkenzieherwirbel)。借此可以减小螺旋形压力室中的湍流损失(Turbulenzverlust)。
在有利且紧凑的部件共同作用中，分流件位于封装件上。
所述径流式通风机的一个有利实施进一步提出：分流件形成为套筒，该套筒插入模仿密封罐的空隙中。形成为套筒，这使得分流件能够承担附加功能，例如轴体的安装。同时，借此可确定分流件的位置。
从流体技术角度看有利的是：分流件相对于封装件的径向内壁面沿径向突出，从而形成压力室的轴向面。螺旋形压力室轴向邻接扩散件，其中，分流件有利地在第一轴向侧形成用于扩散件的流动面，并且在相对的轴向面上形成用于螺旋形压力室的轴向壁面。
在一个实施方式中，分流件具有筒状的轴向凹陷，该凹陷的直径等于通风机叶轮的外径。通风机叶轮部分地沿轴向插入凹陷中，使得通风机叶轮所输出的流直接受到分流件的径向相接区段(该区段形成扩散件)的影响。凹陷使得通风机叶轮和分流件在轴向上结构紧凑。
所述径流式通风机在一个实施变体中进一步包括至少一个用于安装轴体的轴承，该轴承布置在分流件与轴体之间。优选设置两个轴向间隔开的轴承，这两个轴承被弹簧张紧并且分别布置在分流件与轴体之间。
在进一步方案中，所述径流式通风机的特征在于：分流件在其朝向压力室的自由端上至少局部具有倒圆部。倒圆部特别是设置在扩散件的径向末端上，以改善进入压力室的切向入流。
作为所述径流式通风机进一步的实施变体，封装件的轴向突出的环形区段在其径向外缘区段上具有环周延伸的轴向突出部，该轴向突出部贴靠壳体部件的内壁面。由此在压力室中的内侧部件中形成轴向凹陷，与此同时，通过环周延伸的突出部确保封装件的环形区段与壳体部件之间存在足够的贴靠面。

具体实施方式
图1至图4以一个轴向俯视图、两个剖面图A-A和B-B以及一个透视性剖面图示出根据本发明的径流式通风机1的实施例。
径流式通风机1包括形成为内转子的、具有转子22和定子32的电动马达，转子和定子按密封式马达的样式共同作用。转子22的磁体固定在轴体7上，该轴体沿着旋转轴RA沿轴向延伸穿过径流式通风机1。形成为径流式通风机叶轮的通风机叶轮3紧固在轴体7上，该通风机叶轮工作时通过其叶轮叶片沿轴向透过入口69吸入空气并且透过出口44处的压力接头33吹出空气。
径流式通风机1包括基本部件2和套设在基本部件2上的、带有压力接头33的壳体部件4，该压力接头限定出口44。基本部件2是整体一件式构造单元，在该构造单元中，电动马达的定子32、印制电路板10以及紧固在印制电路板10上的用于控制径流式通风机1的马达电子部件98被一体式塑料封装件17封装起来。在基本部件2中，围绕轴体7的旋转轴RA形成圆柱形空隙92，轴体7和电动马达的固定在轴体上的转子22插入该空隙中，使得转子22和定子32位于一个轴向平面上。空隙92的底部77被封装件17封闭。
封装件17形成沿轴向平行于旋转轴延伸的突出的环形区段11，该环形区段的朝向壳体部件4的轴向端面与壳体部件4一起限定螺旋形压力室D。在环形区段11上的径向外侧形成有轴向突出部18，该突出部形成与壳体部件4的内壁面贴靠的贴靠面。因此，环形区段11的轴向端面呈槽状下陷。在图4中可以清楚看到，环形区段11同时形成位于径向内侧的用于马达电子组件98的容置空间。
包围通风机叶轮3的环形分流件8被布置成沿径向邻接通风机叶轮3，该分流件与壳体部件4的内壁面一起在通风机叶轮3周围形成扩散件9。外侧部件4的内壁面和分流件8在扩散件9区域内垂直于旋转轴RA沿径向向外延伸。分流件8的自由端形成扩散件9的末端并且具有倒圆部R。扩散件9直接与压力室D衔接。压力室D的螺旋形状仅由内侧部件5形成，其中壳体部件4具有恒定直径。如图2至图4中清楚所示，环形区段11的造型既在轴向上又在径向上扩展了压力室D。分流件8相对于内侧部件5的径向内壁面87沿径向突出，并且部分地形成压力室D的上侧轴向面。压力室D轴向偏移，但紧邻扩散件9形成，使得通风机叶轮3所产生的流沿切向从扩散件9流入压力室D中。带有出口44的压力接头33在压力室D的延长部中一件式形成在外侧部件4上并且具有圆形横截面。
壳体部件4在环形区段11的径向外壁面处相对于基本部件2被环周延伸的密封件25密封。此外，在基本部件2上一体式设有用于插接插头以及与印制电路板10接触的插接装置93。
电子部件98被封装件17包围地在自由空间中邻接压力室D布置并且因此而面向流体，借此将热量释放到分流件8上，从而实现冷却。
分流件8位于环形区段11上并且此外形成为套筒，该套筒具有沿轴向插入空隙92中的圆柱形管段，该管段的末端与转子22相隔一定距离。轴体7借助两个轴承19安装在分流件8上。这两个轴承19通过弹簧21沿轴向张紧。作为替代方案，也可以相对于基本部件2中的空隙92来安装轴体7。此外，也可以相对于分流件8安装其中一个轴承19，相对于基本部件2安装第二个轴承19。
分流件8在通风机叶轮3这一侧具有筒状的轴向凹陷14，通风机叶轮3连同其底盘插入在该凹陷中，使得通风机叶轮3的出口和毗邻的分流件8的表面齐平地位于一个轴向平面中。凹陷14的直径等于通风机叶轮3的底盘的外径，使得从通风机叶轮3到分流件8的过渡是基本无隙的。设置优选为0.2mm至0.5mm的最小间隙以确保通风机叶轮3的旋转。其中，“基本无隙”的意思是通风机叶轮3相对于分流件8的旋转是有保证的。
