Description

一种大功率永磁传动装置的强制散热方法
技术领域
本发明涉及一种大功率永磁传动装置的风冷罩。
背景技术
目前，在大功率永磁传动结构中，冷却方式有3种，一种是散热片冷却，一种是离心叶片冷却，还有就是水冷。大功率永磁传动的一般特点是转速低(1000-1500rpm)，发热量大，系统自身的风冷装置由于转速低，无法满足快速散热的要求。目前在大功率永磁传动装置上采用的水冷装置存在着成本高、密封困难、易腐蚀、结构复杂、占用轴向空间大等诸多问题。
发明内容
本发明的目的是提供一种一种大功率永磁传动装置的强制散热方法，该风冷罩结合引风机及连接风道，可有效实现大功率永磁传动装置的主动式强制风冷散热，通过调整外置引风机的风量能够有效的控制永磁传动装置的散热能力。
为实现上述目的，本发明通过以下技术方案实现：
一种大功率永磁传动装置的强制散热方法，其特征在于，采用外置的风机、管道及风冷罩对永磁传动装置进行强制散热，通过调整外置风机的风量风速来控制永磁传动装置的散热能力；风冷罩包括上壳体、下壳体、进出风接口板，所述的上壳体与下壳体形成永磁传动装置的壳体结构，永磁传动装置的传动轴伸出壳体外；进出风接口板上设有进风口、出风口，进风口及出风口上分别通过法兰盘连接进、出风管道，进、出风管道连接外置的风机；所述的风冷罩进风口处设有增强散热效率的扰流板，扰流板为多个，分别设置于进出风接口板及下壳体上；所述的进风口处还设有使进风气流吹向永磁机构传动轴的轴向风导流板，轴向风导流板设置于下壳体上。
所述的扰流板设置于风冷罩进风口的两侧，扰流板为钢板切割成型结构。
所述的轴向风导流板位于风冷罩进风口的两侧，为钢板弯曲成型结构，设置于扰流板的另外两侧相对设置。
与现有技术相比，本发明的有益效果是：
1、永磁传动装置的风冷散热不再依赖自身的旋转离心散热和散热片的散热，有效解决了风量不足造成的散热差的问题。
2、风冷散热能力可以通过控制引风机的风量来控制，与永磁传动装置的转速无关。
3、与水冷散热相比，风冷风冷罩比水冷结构的壳体轻便，成本低，密封要求低，没有油水泄露、混合问题，几乎不增加对轴向空间的占用，结构紧凑。
4、风冷罩把整个永磁传动装置封闭起来，提高了安全性。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细叙述。
见图1，一种大功率永磁传动装置的强制散热方法，采用外置的风机、管道及风冷罩对永磁传动装置进行强制散热，通过调整外置风机的风量风速来控制永磁传动装置的散热能力。
所述的大功率永磁传动装置的立式风冷罩由上壳体1、下壳体3、进出风接口板4三个部分组成，各部分制造方式为钢板切割成型及弯曲成型后焊接，各部分之间采用螺丝连接。所述的上壳体1与下壳体3形成永磁传动装置的壳体结构，永磁传动装置的传动轴伸出壳体外；进出风接口板4上设有进风口6、出风口5，进风口6及出风口5上分别设有连接进、出风管道的法兰盘。上壳体1与下壳体3组成永磁传动装置的外壳，进风口6处设有扰流板7，扰流板7的作用是增强散热效率，通过改变进风的气流流向，增加换热时间，使进风气流的流向能够吹向永磁机构导体盘9，加强散热效果。扰流板为多个，分别设置于进出风接口板4及下壳体3上。进风口6处还设有轴向风导流板8，轴向风导流板8设置于下壳体3上。轴向风导流板8的作用是引导进风空气流向永磁机构传动轴上，起到对轴进行冷却的作用，能够有效防止热量通过轴向电动机传导。
所述的进风口6、出风口5为方形结构(也可为圆形)，扰流板7设置于风冷罩进风口6的两侧，扰流板为钢板切割成型结构。轴向风导流板8位于风冷罩进风口的另外两侧，起到将进风气流导向永磁机构传动轴的作用，轴向风导流板8为钢板弯曲成型结构。
本发明所述的进出风接口板4用于对接外置的进风和出风管道，其接口部分法兰使用螺丝与管道连接。本发明所述的大功率永磁传动装置的下壳体3与进出风接口板4的法兰孔重合，安装时用螺丝杆一体固定在设备基础之上。
