More Information
Summary:The invention relates to the field of engineering machinery, in particular to an electric excavator complete machine heat management system which comprises an oil radiator and a condenser matched with the oil radiator, the oil radiator is connected with a first heat exchanger through a pipeline to form a heat supply loop, and the oil radiator is connected with a proportional valve through a pipeline to form a control loop. A first distribution valve is installed on the heat supply loop and connected with a first heat exchanger through a branch pipeline, and the first heat exchanger is connected with a cab through a heat dissipation pipeline to form a first cab heat dissipation loop to dissipate heat of the cab. The first heat exchanger is connected with the battery through a pipeline to form a first battery heat dissipation loop to dissipate heat of the battery. According to the complete machine heat management system of the electric excavator, heat generated by a hydraulic oil circuit is conveyed to a batter
