Ventilation structure of industrial electric machine and industrial electric machine

Abstract

This utility model provides a ventilation structure for an industrial motor and an industrial motor itself, belonging to the field of industrial motor ventilation. It addresses the problem that when the motor operates in harsh environments (such as high temperatures and high dust levels), the ambient air around the motor casing is often insufficient to meet heat dissipation requirements. The structure includes a guide shroud and an extension pipe. By replacing the perforated shroud of the industrial motor with an integrally molded guide shroud, it solves the problems of high wind resistance and poor connection reliability caused by the separate splicing of the perforated shroud and the extension pipe in the prior art. Furthermore, the smooth curved surface reshapes the flow field distribution within the channel, and combined with the sealed delivery of the extension pipe, it achieves low-loss ventilation throughout the entire process from the cold source to the internal heat dissipation fins of the motor, significantly improving cooling efficiency and operational reliability.
