Heat dissipation system for low-voltage pure electric micro-excavator and control method of heat dissipation system
The invention discloses a heat dissipation system for a low-voltage pure electric micro excavator and a control method thereof, and relates to the technical field of engineering machinery, the heat dissipation system comprises an MCU cooling fan, an electronic fan and a complete machine controller VCU, the complete machine controller VCU is further connected with a motor controller MCU and a hydraulic oil temperature sensor, and the motor controller MCU and the hydraulic oil temperature sensor are connected with a power supply. And the controller is used for receiving the oil temperature signal and a signal fed back by the motor controller MCU and sending out a corresponding instruction. Real-time temperature monitoring is conducted on hydraulic oil and the motor controller MCU through the whole machine controller VCU, the hydraulic oil and the motor controller MCU are subjected to integrated control, meanwhile, starting of the two fans is controlled through different preset values of the temperature of the motor controller MCU, different rotating speeds are adjusted, when the temperature of the hydraulic oil exceeds the temperature of the motor controller MCU, starting of the electronic fans has the priority level, and the starting efficiency of the electronic fans is improved. By means of the mode, energy can be fully utilized, the problems in the prior art are solved, unnecessary energy waste is reduced, normal and stable operation of the whole machine is guaranteed, and heat of hydraulic oil and the motor controller MCU is effectively dissipated.
