Description

一种大功率永磁传动装置的卧式风冷罩
技术领域
本实用新型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。在另外，在现场比较狭小的时候，难以做立式风冷。
发明内容
本实用新型提供一种大功率永磁传动装置的卧式风冷罩，设计主动式风冷散热结构，采用外置引风机、管道和散热罩对永磁传动装置进行强制散热，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，本实用新型通过以下技术方案实现：
一种大功率永磁传动装置的卧式风冷罩，其特征在于，包括上壳体、下壳体，上壳体、下壳体组成永磁传动装置的壳体结构，永磁传动装置的传动轴伸出于壳体；在壳体的侧部与永磁传动装置传动轴垂直方向设有进风口和出风口，在壳体内部进风口两侧设有增强散热效率的扰流板和起进风导流作用的轴向风导流板。
所述的进风口、出风口处均设有连接法兰，进风口、出风口通过连接法兰与外部进风、出风管道相连接。
与现有技术相比，本实用新型的有益效果是：
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，风冷散热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、散热罩把整个永磁传动装置封闭起来，提高了安全性。
5、卧式风冷罩进出风口在一侧，能够适应无法做地下管路的情况。

具体实施方式
见图1大功率永磁传动装置的卧式风冷罩由2个主要部分组成：上壳体1、下壳体8，上壳体1、下壳体8组成永磁传动装置的壳体结构，永磁传动装置的传动轴伸出于壳体；在壳体的侧部与永磁传动装置传动轴垂直方向设有进风口3和出风口6，在壳体内部进风口3两侧设有增强散热效率的扰流板4和起进风导流作用的轴向风导流板9。扰流板4和轴向风导流板9为钢板切割成型及弯曲成型后焊接在壳体上。
所述的进风口3、出风口6处均设有连接法兰，进风口3、出风口6通过连接法兰与外部进风、出风管道相连接。采用外置引风机、管道和散热罩实现对永磁传动装置进行强制散热，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。
进风口扰流板4的作用是增强散热效率，增加冷空气在罩体内的换热时间，使进风气流能够有效吹向永磁传动装置的导体盘，加强导体盘散热效果。
轴向风导流板9的作用是引导部分空气流向永磁传动装置的传动轴上，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。
本实用新型所述的大功率永磁传动装置的卧式风冷罩的进风口法兰2使用螺丝与进风管道连接。
本实用新型所述的大功率永磁传动装置的卧式风冷罩的出风口法兰5使用螺丝与出风管道连接。
本实用新型所述的大功率永磁传动装置的卧式风冷罩的下壳体基座7用螺丝杆一体固定在设备基础之上。
