Pain point

New energy vehicle water-cooled electric drive assembly performance improvement solutions

The main solution is that the temperature control of the water-cooled electric machine is not accurate, and the flow is unstable; The platform communication is cumbersome and can not solve the problem of communication coordination at one time, which is difficult to meet the stage of temperature control, rapid rise and fall, stable flow output at different temperatures, and the platform integrates different suppliers of equipment coordination communication.

Solution (Select equipment)

AODE high and low temperature liquid intelligent temperature control equipment ACH10WD-12KW-30S

AODE high and low temperature liquid intelligent temperature control equipment can achieve intelligent temperature, flow, pressure regulation and monitoring, stable operation of the unit, high temperature control precision, fast heating rate, complete safety protection functions (overload protection, reverse phase loss protection, high and low pressure protection, low liquid level protection, freezing point protection, etc.), temperature control range can reach -40 ~ +120℃. Temperature accuracy ±0.5℃, using piston compressor and magnetic drive circulation pump, evaporator and condenser are stainless steel welded plate.

After the power is switched on, the temperature control system automatically starts the electric heating tube to convert the electric energy into heat energy, and the temperature in the tank rises evenly to the temperature of the top line. The temperature control system automatically cuts off the power and enters the heat preservation state. After holding the tank for a period of time, the temperature naturally drops. This continuous cycle ensures that the temperature is controlled within the set value range, maintaining a constant temperature and more accurate control.

In addition, the AODE high and low temperature control system has the following three advantages

1. High pump stability: the automotive testing industry needs a long period, high and low temperature test, magnetic pump for magnetic driven high and low temperature vortex pump, pump with small volume, low vibration, low noise, small heat, never leak and other characteristics, used in -80-350℃ test experiment.

2. High flow accuracy: the flow meter of the automotive test industry generally uses 0.5% accuracy flowmeter, most of the test flow range is 2-40L/min, when the low-temperature medium becomes viscous, the low-flow area of the ordinary flowmeter is difficult to ensure accuracy, pinion flowmeter has the advantage of higher accuracy, shorter response time, low flow rate, higher frequency, suitable for measuring high-viscosity media.

System design optimization: the car test is basically with heat, so the cooling capacity of the low temperature area is especially precious, and it is necessary to reduce the heat of the temperature control equipment itself as much as possible while improving the cooling rate as much as possible. The number of high and low temperature control system pumps is less, and the cooling rate is faster; Single refrigeration system, simple, energy-saving, cost-effective; Greater cooling capacity and less loss.

Effect

Through the deployment of AODE, the Oems can reduce the test cycle caused by equipment failure and help improve the safety and reliability of the vehicle.
