Novel vertical motor cooling system

Abstract

The invention discloses a novel vertical motor cooling system, and relates to the technical field of motors. The novel vertical motor cooling system comprises a cooler main body, an inner wind path extension separating cavity, a main fan, a main wind guide cylinder, a fan cover, an outer fan and an auxiliary wind guide cylinder, wherein the inner wind path extension separating cavity is formed ina motor shell arranged at the inner side of the lower end of the cooler main body; the inner fan is arranged above the inner wind path extension separating cavity; the outer fan is arranged on the upper end of the cooler main body; the fan cover is arranged at the outer part of the outer fan; the main wind guide cylinder is arranged at the outer part of the fan cover; the auxiliary wind guide cylinder is arranged in the main wind guide cylinder. According to the novel vertical motor cooling system disclosed by the invention, heat exchange is more sufficient and more efficient, and the coolingspeed of a motor is increased; meanwhile, a top bearing can be cooled, an external apparatus is not needed, the equipment operation stability is increased, and a more friendly working environment canbe provided for a motor operation scene.

Description

technical field [0001] The invention relates to a novel vertical motor cooling system, which belongs to the technical field of motors. Background technique [0002] At present, it is more common that some vertical motors with higher protection level requirements (usually up to IP54) generally use the "IC611" cooling method. This cooling method is commonly known as closed air-to-air cooling, and its corresponding motor cooling system has the following characteristics: the primary cooling medium (referring to the air inside the motor) circulates in a closed loop, and the secondary cooling medium (referring to the air around the motor) is directly installed in the The external cooler on the motor transfers heat to the surrounding environment, and the flow of primary or secondary cooling medium is realized by the fan rotating with the motor. [0003] Usually, the setting of the internal circulation air path of the motor is circuitous and complicated, the wind resistance is larg...

AI Technical Summary

Problems solved by technology

In this way, the internal and external air paths of the motor can be regarded as flowing in the same direction when they are in the cooler, which reduces the heat transfer effect of the cooler

At the same time, the temperature of the hot air blown from the bottom of the cooler is relatively high, especially when the motor is running in the high temperature season, the personnel who perform relevant operations on the platform must endure a relatively harsh working environment

In addition, when the vertical motor bears a large load and the ambient temperature is high, the heating of the thrust bearing on the top will become more serious. Usually, the user needs to equip another fan to cool the top bearing, which increases the temperature of the motor. Operating cost and maintenance complexity
