AI Technical Summary

Technical Problem

The existing electric tricycle motor cooling system cannot be flexibly adjusted according to the motor's real-time heat generation, resulting in energy waste under light loads and insufficient heat dissipation under heavy loads, affecting the motor's lifespan and efficiency.

Method used

A water-cooled circulation system combined with a temperature sensor and an air-cooled system is adopted. Heat is absorbed through water-cooled pipes and heat-conducting plates, the liquid is cooled by a cooler, and the fan is activated to dissipate heat when the temperature exceeds the limit, so as to achieve real-time control of motor temperature.

Benefits of technology

It effectively protects the motor, prevents insulation aging and increased winding resistance, extends motor life, reduces maintenance frequency, and improves the power output stability and safety of electric tricycles.

Abstract

The utility model discloses an electro-tricycle motor heat dissipation device which comprises a driving box, the right side face of the driving box is connected with a water cooling circulating pump, the right side face of the driving box is connected with a refrigerator, the inner bottom wall of the driving box is connected with a water cooling pipe, and the inner wall of the driving box is connected with a heat conduction plate. The bottom face of the heat conduction plate makes contact with a water cooling pipe, and one end of the water cooling pipe communicates with the input end of a water cooling circulating pump. According to the device, cooling liquid is continuously pushed to circulate through the water-cooling circulating pump, a large amount of heat generated by the driving motor can be rapidly and efficiently absorbed through close contact of the water-cooling pipe and the heat conduction plate, the cooling liquid is cooled by means of the refrigerator, the continuity of heat dissipation is ensured, and when the temperature sensor monitors that the temperature of the motor is too high, the air cooling system can be triggered; the driving machine drives the cooling fan blades to operate, external cold air is introduced for further cooling, and the driving machine and the cooling fan blades work cooperatively, so that the temperature of the driving motor can be controlled within a suitable range all the time.
