The invention provides an electric tractor complete machine cooling system, and belongs to the technical field of automobile heat management. The system comprises an air conditioning system, a power battery cooling system, a dual-motor cooling system and a controller. The air conditioning system refrigerates a passenger compartment, the power battery cooling system can provide a general cooling mode and is coupled with the air conditioning system through a battery cooler, and a rapid cooling mode is provided for the power battery by means of a refrigerating capacity of the air conditioning system under severe working conditions. The dual-motor cooling system can independently or simultaneously cool a main motor and an auxiliary motor. Real-time temperatures collected by the temperature sensors are input into the controller, the temperatures of all parts are automatically adjusted through the controller, the refrigeration requirement of the passenger compartment is met, the power battery can be kept within a temperature interval of efficient work, the temperature of the motor can be controlled to be lower than a safe work limit value, working safety and comfort are guaranteed, and the continuous working time of the tractor is prolonged.

    本发明提出了一种电动拖拉机整机冷却系统,属于汽车热管理技术领域,包括空调系统、动力电池冷却系统、双电机冷却系统和控制器。空调系统为乘员舱制冷,动力电池冷却系统除了能提供一般冷却方式,还和空调系统通过电池冷却器耦合在一起,在恶劣工况下借助空调系统的制冷能力为动力电池提供快速冷却方式,双电机冷却系统可以实现独立或同时对主电机和副电机进行冷却。本发明将多个温度传感器上采集的实时温度,输入到控制器中,经控制器对各部分温度进行自动调节,满足乘员舱的制冷需求,能将动力电池保持在高效工作的温度区间内,能将电机温度控制在安全工作限值以下,保障了工作的安全性和舒适性、延长了拖拉机连续作业时间。
