AI Technical Summary

Technical Problem

The existing automotive cooling fan's clamp joint line strength is insufficient, which can easily become the starting point of failure. Increasing the clamp thickness will increase the mass and centrifugal stress.

Method used

Reinforcing ribs or thickened areas are added at the joint line of the fan clamp to improve the strength of the joint line, while reducing the increase in the mass of the clamp and the effect of centrifugal stress.

Benefits of technology

The strength of the fan clamp joint line was enhanced, the impact of increased mass and centrifugal stress was reduced, and the overall structural robustness of the fan was improved.

Abstract

一种风扇，包括：毂部，其被构造成由马达驱动以围绕风扇旋转轴线旋转；叶片，其从毂部径向突出；以及箍，其围绕旋转轴线并连接叶片的末端。该箍包括在结构上加强结合线的特征。在一些实施例中，所述特征是在远离毂部的方向上从箍的外表面突出的加厚区域。加厚区域设置在每对相邻叶片的相应末端之间。在一些实施例中，所述特征是从所述箍的面向毂部的表面突出的结构加强肋。肋设置在每对相邻叶片的相应末端之间。在一些实施例中，特征是肋和加厚区域两者。
