Self-ventilation motor fan housing capable of enhancing capacities of heat dissipation and protection

Abstract

The invention provides a self-ventilation motor fan housing capable of enhancing the capacities of heat dissipation and protection and resolves the problems that an existing self-ventilation motor is poor in protective capability of an air inlet-outlet and low in reliability when temperature rise of the motor is overhigh. The self-ventilation motor fan housing capable of enhancing the capacities of the heat dissipation and the protection comprises a fan housing body which is arranged on the air inlet-outlet of the motor, the fan housing body comprises a shell body, an arch-shaped plate is arranged at the upper end of the shell body, wherein a hole is formed in the middle of the arch-shaped plate, the arch-shaped plate is connected with an outer shell of the motor in a matched mode, a plurality of louver-type wind plates are arranged on the front side and the back side of the shell body, air ports are formed in the lower portions of the plurality of louver-type wind plates, and a water leakage hole is formed in the bottom of the shell body. The self-ventilation motor fan housing capable of enhancing the capacities of the heat dissipation and the protection is reasonable and reliable in structural design and capable of improving cooling effect, meanwhile, the motor is good in the protective capacity, high in reliability and low in a failure rate. Due to the fact that the temperature rise of the motor is lowered, the core length of an effective part of the motor can be reduced, the size is reduced, the weight is reduced, cost is lowered, the demands for low-floor and light weight of the motor of users can be satisfied.

Description

Technical field [0001] The invention relates to the component parts of a self-ventilating motor, in particular to a self-ventilating motor wind cover with enhanced heat dissipation and protection capabilities. Background technique [0002] An electric vehicle is a new energy green vehicle that has emerged in recent years. It uses electric energy as a power source and drives the vehicle through a power traction system composed of a controller and a traction motor. Compared with traditional fuel vehicles, it has the advantages of zero emission, no pollution, energy saving, consumption reduction and environmental protection. The core of the electric vehicle is the power drive system, including the controller and the traction motor. When the electric vehicle is fully loaded and climbing, the traction motor is required to output greater power and torque. The increase in power will cause the traction motor to generate serious heat. In severe cases, it may burn the motor. The motor is ...
