Problems solved by technology

In the prior art, the windshield of the air-to-air-cooled three-phase asynchronous motor consists of two parts, namely the upper part and the lower part; There is no wind deflector in the middle of the motor, resulting in low wind pressure and large wind resistance, so the heat dissipation effect of the air-cooled three-phase asynchronous motor is poor

Abstract

The invention relates to an air-air cooling three-phase asynchronous motor fan cover, comprising a connecting frame which is provided with an air inlet; the connecting frame is respectively provided with an upper junction plate, a middle junction plate and a lower junction plate, wherein the other ends of the upper junction plate, the middle junction plate and the lower junction plate is respectively provided with a first wind screen, a second wind screen and a third wind screen; the end of the first wind screen and the end of the wind screen are provided with bottom-end junction plates, and the lower part of the first wind screen is provided with an air outlet which is communicated with the air inlet. The first wind screen, the third wind screen, the bottom-end junction plate and the connecting frame in the invention form a fan cover structure. Compared with the existing fan cover, the air-air cooling three-phase asynchronous motor fan cover can reduce the working procedure of immovable fitting, avoids windage resistance caused by that cooling air flow generated by an outer fan suddenly turns; the upper junction plate and the first wind screen, the middle junction plate and the second wind screen and the lower junction plate and the third wind screen all adopt circular arc transition, thus bringing smoother air flow path flowing, enlarging a wind collection chamber and improving heat dissipation effect.

Description

technical field [0001] The invention relates to a wind cover, in particular to an air-to-air cooling three-phase asynchronous motor wind cover. Background technique [0002] Air-cooled three-phase asynchronous motor is a three-phase asynchronous motor that uses air to cool the motor. At present, the demand for YKK series motors is increasing year by year, but when YKK series motors are used, the temperature rises higher; the structure of the motor windshield is a very important factor affecting the higher temperature rise of the motor. In the prior art, the windshield of the air-to-air-cooled three-phase asynchronous motor consists of two parts, namely the upper part and the lower part; There is no wind deflector in the middle of the motor, resulting in low wind pressure and large wind resistance, so the heat dissipation effect of the air-cooled three-phase asynchronous motor is poor. Contents of the invention [0003] The purpose of the present invention is to overcome ...
