Abstract

本实用新型公开了一种电机风扇,包括扇体、扇叶;扇叶沿圆周方向均布在扇体上;扇叶端部在轴截面内呈长方形;进一步改进在于:扇叶端部相邻边的过渡圆角半径R不大于5mm。本实用新型结构简单,风量大,散热效果好。

Description

电机风扇
技术领域
本实用新型涉及电机技术领域,具体涉及电机风扇。
背景技术
电机在运转过程中产生一定的热量,电机内设有风扇以散热。现有技术的风扇端部在轴截面内是圆弧形或锥形结构,风量较小,如电机产生的热量较多,则无法满足电机的散热需要。
发明内容
本实用新型针对现有技术的不足,提出一种结构简单,风量大,散热效果好的电机风扇。
本实用新型通过下述技术方案实现技术目标。
电机风扇,包括扇体、扇叶;所述扇叶沿圆周方向均布在扇体上;其改进之处在于:所述扇叶端部在轴截面内呈长方形。
上述结构中,所述扇叶端部相邻边的过渡圆角半径R不大于5mm。
本实用新型与现有技术相比,具有以下积极效果:
1、本实用新型扇叶端部在轴截面内呈长方形,产生的风量大,即使电机产生的热量较多,也能满足电机的散热需要。
2、本实用新型扇叶端部相邻边的过渡圆角半径越小,扇叶的截面积越大,产生的风力越大。
附图说明
图1为本实用新型结构示意图。
图2为图1的左视图。
具体实施方式
 下面根据附图并结合实施例对本实用新型作进一步说明。
附图所示的电机风扇,包括扇体1、扇叶2;所述扇叶2沿圆周方向均布在扇体1上;所述扇叶2端部2.1在轴截面内呈长方形;所述扇叶2端部2.1相邻边的过渡圆角半径R不大于5mm。

Claims (2)

1.一种电机风扇,包括扇体(1)、扇叶(2);所述扇叶(2)沿圆周方向均布在扇体(1)上;其特征在于:所述扇叶(2)端部(2.1)在轴截面内呈长方形。
2.根据权利要求1所述的电机风扇,其特征在于:所述扇叶(2)端部(2.1)相邻边的过渡圆角半径R不大于5mm。
