1. Radiator: used for heat exchange between the coolant and the surrounding air to dissipate the heat generated by the excavator.
2. Fan: By providing airflow to accelerate the cooling effect of the coolant. The fan can be mechanically or electrically driven, depending on the excavator model and design.
3. Coolant pump: responsible for circulating the coolant and sending it to the radiator to reduce the temperature. The pump is usually driven by the engine of the excavator.
4. Temperature sensor: used to monitor the temperature change of the excavator. The sensor detects the temperature of the coolant and sends a signal to the control system to automatically adjust the operation of the cooling system.
5. Control system: According to the temperature information fed back by the sensor, control the operation of fans, coolant pumps and other equipment to maintain the excavator working within the safe temperature range.
