Abstract

In this work, The structure of a cooling system for FSEC racing motor is designed, and its 3D geometric model is established and assembled on a real car. Through the simulation method, the temperature field cloud diagram of the radiator is obtained, and the influence of key parameters such as the inlet and outlet location of the heat exchanger, inlet flow rate and the number of cooling pipes on the temperature change of the cooling system is analyzed. The heat dissipation simulation analysis of the heat exchanger was carried out under conditions close to the competition field, and the outlet temperature was maintained at 76℃. The cooling system of the driving motor was tested on the bench and the durability test of the loading. The data verified the reliability and stability of the cooling system of the driving motor. The drive motor cooling system is designed to allow the motor and motor controller to operate continuously at suitable temperatures (25 ° C to 120 ° C). The simulation analysis method and test results have certain practical significance for the design of FSEC racing motor cooling system.

FSEC赛车驱动电机冷却系统的设计与分析

本文设计了FSEC赛车发动机冷却系统的结构，建立了其三维几何模型，并在实际车上进行了装配。通过仿真方法得到散热器温度场云图，分析了换热器进出口位置、进口流量、冷却管数等关键参数对冷却系统温度变化的影响。在接近比赛场地的条件下对换热器进行散热模拟分析，出口温度保持在76℃。对驱动电机的冷却系统进行了台架试验和载荷耐久性试验。实验数据验证了驱动电机冷却系统的可靠性和稳定性。驱动电机冷却系统的设计是为了使电机和电机控制器能够在合适的温度(25℃~ 120℃)下连续运行，仿真分析方法和测试结果对于FSEC赛车电机冷却系统的设计具有一定的现实意义。
