Abstract

串联连接的多个风扇,包括:至少两个串联连接的风扇;以及转换装置,该转换装置布置在两个风扇之间。转换装置由柱形外壳和多个平面板组成,各平面板从柱形外壳的中心轴线沿径向延伸至柱形外壳的内周壁,并在柱形外壳中沿轴向延伸。这两个风扇同轴连接,且设计得基本彼此相同。

Description

串联连接的多个风扇
技术领域
本发明涉及串联连接的风扇,特别是涉及串联连接的多个风扇,这些风扇有布置在上游侧的风扇和下游侧的风扇之间的转换(commutation)装置。
背景技术
轴流风扇已经用作空调装置、个人计算机、服务器等的冷却风扇。日本专利申请公开No.349476/2002公开了串联连接的风扇,这些风扇包括至少两个轴流风扇,其能够在空气通道的流阻较大的情况下增加空气流的量。
希望使串联连接的风扇的最大空气速度等于一个风扇的最大空气速度,且串联连接的风扇的静压比一个风扇的静压大大约2倍。不过,普通的串联连接的风扇的静压比一个风扇的静压大大约1.5倍。具有固定叶片的串联连接的风扇的静压比一个风扇的静压大大约1.8倍。在串联连接的风扇中,风扇彼此沿相同方向旋转,因此,旋转流分量包含在从上游侧风扇引向下游侧风扇的空气流的速度分量中,且具有旋转流分量(方向类似于下游侧风扇的旋转方向)的空气流进入下游侧风扇,因此,下游侧风扇的相对旋转速度变小,且串联连接的风扇的能力降低。
发明内容
本发明的目的是解决上述缺陷。
上述目的可以通过串联连接的多个风扇来实现,这些风扇包括:至少两个串联连接的风扇;以及转换装置,该转换装置布置在两个风扇之间,且该转换装置由柱形外壳和多个平面板组成,各平面板从柱形外壳的中心轴线沿径向延伸至柱形外壳的内周壁,并在柱形外壳中沿轴向延伸。
通过结合下面的说明和附图,将更清楚和理解本发明的这些和其它方面和目的。不过应当知道,尽管下面的说明表示了本发明的优选实施例,但是它只是进行举例说明,而不是进行限定。在不脱离本发明的精神的情况下,可以在本发明的范围内进行多种变化和改变,且本发明包括所有这些变化。
附图说明
图1是本发明的串联连接的风扇的垂直侧剖图,其中一部分被切除。
图2是图1中所示的风扇的正视图。
图3是在本发明的串联连接的风扇中的转换装置的正视图。
图4是图3的转换装置的透视图。
具体实施方式
如图1和图2所示,本发明的串联连接的风扇包括:上游侧的风扇1和下游侧的风扇2,两者的设计彼此相同,且相互同轴连接;以及转换装置3,该转换装置插入风扇1和2之间。
上游侧的风扇1和下游侧的风扇2各自包括:柱形外壳4;马达6,该马达6布置在柱形外壳4中,并通过支承部件5而固定在该柱形外壳4上;以及活动叶片7,如图1和图2所示。
转换装置3包括:柱形外壳8,该柱形外壳8的直径基本与柱形外壳4类似;以及多个平面转换板9,这些平面转换板9轴对称地布置在柱形外壳8中,以便从柱形外壳8的中心沿径向方向延伸至柱形外壳8的内周壁,并在柱形外壳8中沿轴向延伸。
在本发明的串联连接的风扇中,在来自上游侧风扇1的空气流的旋转流分量中的动压通过转换装置3而变成升高的静压,这样,由下游侧的风扇2接收的空气流的旋转流分量减小。因此,防止下游侧风扇2的能力降低,且风扇噪音降低。
而且,活动叶片7的压力干扰面积能够减小,因为转换装置3的转换板9轴对称地布置。
转换装置3能够通过注射模制而以较低成本制造。
即使在各自有长度为大约1英寸的柱形外壳8的风扇中,也可以实现具有本发明的转换装置3的串联连接的多个风扇的效果。通过增加柱形外壳8的长度,该效果能够增加。
尽管已经通过本发明优选实施例而特别表示和介绍了本发明,但是本领域技术人员应当知道,在不脱离由后附的权利要求确定的本发明精神和范围的情况下,可以对形式和细节进行各种变化。
