Do car batteries need cooling?
Batteries generate a large amount of heat during operation, and if not treated promptly and effectively, they will be in an extremely unstable state.
Liquid cooling is usually used to ensure the stable working performance of the battery. As shown in the figure, the heat from the battery will gradually transfer to the water cold plate (solid conduction, heat transfer from high to low temperature), and then the coolant will flow in the channel to cool the water cold plate.
What is the function of the battery cooling plate?
Liquid cold plate are usually made of aluminum as the main material and are mainly used for battery pack cooling solutions. This is a cooling method superior to air cooling. By transferring heat from the battery to the two-phase coolant, coupled with the internal channel circulation of the cold plate, local heat dissipation of the battery is achieved and optimal charging and discharging performance is achieved.
The Awind team has professionally designed and optimized the liquid flow path, flow balance, material compatibility, fluid stability, temperature uniformity, weight, and other aspects of the liquid cold plate to meet the optimal cooling effect of different battery cooling systems. Of course, if you have any custom requirements, you can contact our engineers online for online design.
Advantages of water cold plate:
The battery cold plate is made of lightweight aluminum, which can stabilize the temperature of the battery unit and provide the best temperature uniformity.
Liquid cooled plate for installing battery modules shell
Lightweight, vacuum brazing, have good sealing performance
Flow balance design to achieve uniform battery pack temperature
The advantages of vacuum brazing include uniform heating, strict temperature control, no need for cleaning processes, and process repeatability.
Compared to other metal connection processes, vacuum brazing does not melt the base metal of the joint, allowing for more precise tolerance control.
Compared to the local connection process, vacuum brazing also minimizes part deformation caused by uniform heating and cooling.
Vacuum brazing significantly improves the corrosion resistance of the product and eliminates various types of pollution due to the use of brazing flux;
The wettability and flowability of vacuum brazing filler metal are good, which can weld more complex and narrow channel devices.
Vacuum brazing improves the product yield;
Vacuum brazing eliminates the need for cleaning processes, which can reduce production costs.
