Specifications

Peak temperature difference

{'zh': '10.5', 'en': '10.5'} °C

Advantages

Lower temperature difference at high ambient

At ambient temperatures of 35°C and 40°C, the fixed temperature difference strategy (Strategy 3) avoids the peaks in temperature difference seen with the fixed inlet temperature strategy (Strategy 1), offering a compromise in uniformity.

Lowest temperature rise at low ambient

At 25°C ambient temperature, the fixed inlet temperature strategy (Strategy 1) achieves the best temperature rise control.

Broad applicability

The derived conclusions are applicable under various coolant velocities, channel numbers and flow direction layouts.

Applications

• Battery Thermal Management：Match optimal cooling strategy to ambient temperature to control temperature rise and difference.
• Traction Battery Cooling：Ensure temperature uniformity of traction batteries across wide ambient temperatures.
• Liquid Cooling Plate Design：Validate cold plate thermal performance under different control strategies.
• Temperature Control Strategies：Compare strategy pros and cons to guide inlet temperature setting.
