A wind pressure self-increasing motor cooling device based on Bernoulli's principle

Abstract

The invention relates to the technical field of motor equipment and accessories, and discloses a wind pressure self-increasing motor cooling device based on Bernoulli's principle, which includes a motor casing, and a stator is fixedly connected to the inside of the motor casing. The inside of the shell is fixedly connected with a bearing, the outside of the bearing is fixedly connected with a main shaft, the outside of the main shaft is fixedly connected with a rotor, the outside of the main shaft is fixedly connected with a first gear, and the outside of the first gear is meshed with a The second gear, through the cooperation of the main air inlet, the air passage, the inner air inlet, the outer air inlet and the air outlet screen, makes the air flow from the main air inlet, the air passage, the inner air inlet and the air outlet. The outer air inlet hole enters the inside of the motor casing, and the air flows out of the motor casing through the air outlet screen, thereby forming a complete air flow path to ensure smooth air flow and avoid heat dissipation due to poor air flow inside the motor casing The effect is poor, thereby improving the heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of motor equipment and accessories, in particular to a wind pressure self-increasing motor cooling device based on the Bernoulli principle. Background technique [0002] The motor is commonly known as "motor". It is mainly composed of a stator and a rotor. According to the law of electromagnetic induction, the energized wire is forced to move in a magnetic field to realize an electromagnetic device that converts electrical energy into kinetic energy. It completes the effect of making the motor rotate through conduction. During the relative movement of the rotor and the stator, the motor usually generates a large amount of heat, which increases the temperature of the motor. Working in a continuous high-temperature environment tends to reduce the service life of the motor, affect work efficiency, and is not conducive to people's use.

[0002] The motor is commonly known as "motor". It is mainly composed of a stator and a rotor. According to the law of electromagnetic induction, the energized wire is forced to move in a magnetic field to realize an electromagnetic device that converts electrical energy into kinetic energy. It completes the effect of making the motor rotate through conduction. During the relative movement of the rotor and the stator, the motor usually generates a large amount of heat, which increases the temperature of the motor. Working in a continuous high-temperature environment is likely to reduce the service life of the motor and affect work efficiency, which is not conducive to people's use.

[0003] However, the existing motors are usually provided with a single-sided ventilation hole, and are connected to the main shaft of the motor through the fan blade, so that the main shaft drives the fan blade to rotate to complete the heat dissipation of the motor. However, due to the single-sided cooling hole, the air flow is blocked, and the internal and external air flow is not Smooth, and only a single inlet fan blade is provided, which further leads to slow flow of internal and external air, resulting in unsatisfactory heat exchange efficiency with the outside world, resulting in poor heat dissipation of the motor, thereby reducing the service life of the motor and affecting the use of the motor
