Disclosed are a ventilation slot support structure and a motor ventilation slot structure comprising same. The ventilation slot support structure comprises a ventilation slot plate, a ventilation slot support rib, and a spoiler structure. The ventilation slot support rib is fixed to the ventilation slot plate; the spoiler structure is configured to form air disturbance on the ventilation slot plate and is fixed to the ventilation slot plate. The present invention overcomes the defect in the prior art of a large temperature gradient between components due to the fact that a cooling medium cannot sufficiently exchange heat with a winding and a stator core. When air flows through the ventilation slot, the spoiler structure has a disturbance effect on the air, guides the air mostly to the components at a higher temperature, and increases the heat exchange area, making the heat exchange between the components uniform while enhancing the heat exchange effect, thus reducing the temperature difference between the components.
Description
technical field [0001] The invention relates to a ventilation slot supporting structure and a motor ventilation slot structure including the same. Background technique [0002] Excessive temperature rise of the motor will accelerate the aging of the motor insulation, and excessive local temperature gradient of the motor will also cause local stress in the motor, which may cause permanent mechanical damage to the motor. Therefore, the cooling effect of the motor directly affects its service life, and improving the cooling technology plays a key role in ensuring the reliability of the motor. At present, the radial ventilation method is a cooling method widely used in motors. A common cooling air flow path inside the motor is that the cooling air flows through the end of the winding, enters the air gap, and flows from the radial ventilation slot inside the stator core. Cooling of windings and stator core. [0003] In the radial ventilation structure of the existing motor, whe...
