Wound-rotor motor cooler

Abstract

The invention relates to the technical field of motor cooling, especially to a wound-rotor cooler. The wound-rotor cooler comprises a first cooling pipe of a motor slip ring portion and a second cooling pipe of a motor main body portion, wherein the first cooling pipe and the second cooling pipe are in communication with each other. The wound-rotor cooler further comprises a fan mounted on a motor shaft, an air intake hood sleeving outside the fan, and an outer fan housing sleeving outside the air intake hood. A through hole is formed on the outer side surface of the outer fan housing, the motor shaft passes through the through hole, and the diameter of the through hole is the same as the diameter of the motor shaft. An airflow passage is formed between the air intake hood and the outer fan housing, the air intake end of the airflow passage communicates with the second cooling pipe, and the air outlet end of the airflow passage communicates with the outside. When the motor works, air flows from the first cooling pipe to the second cooling, then enters into the airflow passage, and finally is discharged to the outside. Since the slip ring portion emits less heat than the main part of the motor during working, the temperature of the air flowing out of the first cooling pipe rises slightly, and the air then enters into the second cooling pipe, ensuring better cooling effect.

Description

technical field [0001] The invention relates to the technical field of motor cooling, in particular to a cooler for a wound motor. Background technique [0002] Wound motors are widely used in the current mechanical production and other fields. Wound motors are prone to heat during use, and timely heat dissipation plays a good role in protecting the wound motor. For the cooler of the wound motor using IC611 cooling method, It mainly includes the first cooling pipe of the slip ring part and the second cooling pipe of the main part of the motor, the first cooling pipe and the second cooling pipe are connected, and the external cooling air enters the first cooling pipe of the slip ring part One cooling pipe, because the main part of the motor releases more heat, the temperature rises quickly when the external cooling air enters the second cooling pipe, and the cooling effect of the raised external cooling air is poor after entering the first cooling pipe , which is not conduci...
