Water Cooling Device
The water-cooling device should be able to cool the temperature of the circulating fluid in the system to below 60℃, so as to ensure that the converter and traction motor can work normally under vehicle operation. The water cooling device shall automatically adjust the fan speed according to the water temperature at the outlet of the heat exchanger, so as to adjust the water supply temperature of the water cooling device. The water-cooling device uploads the running status and alarm information of the water-cooling device to the vehicle master control through communication.
Detailed introduction
Function description:
The water-cooling device should be able to cool the temperature of the circulating fluid in the system to below 60℃, so as to ensure that the converter and traction motor can work normally when the vehicle is running. The water cooling device shall automatically adjust the fan speed according to the water temperature at the outlet of the heat exchanger, so as to adjust the water supply temperature of the water cooling device.
The water-cooling device uploads the running status and alarm information of the water-cooling device to the vehicle master control through communication.
