Light Cooling Radiator For Electric Vehicle & Motor
The increasing popularity of electric vehicles (EVs), coupled with commercial demand, has driven the development of stronger and more durable batteries.
Electric vehicle manufacturers must overcome cooling barriers to achieve their goals, which means they need to find the cooling solutions that consider thermal efficiency, temperature uniformity, size, weight, and cost. Electric motors also require similar cooling needs.
Electric vehicle manufacturers have explored many cooling technologies, including air cooling, liquid cooling, and phase change materials. Liquid cooling has become the preferred solution for electric vehicle batteries and motors today due to its performance, weight, and size.
For electric vehicles, AWIND has experience in design cooling solutions for electric motors and high-energy dense batteries.
In the design of electric motors, thermal efficiency is a very important factor. In most cases, it is the most important factor. The higher the cooling efficiency of the motor, the higher the operating efficiency of the motor. If the temperature of the copper winding increases, the resistance of the winding increases and the efficiency decreases. Bearings and lubrication are also negatively affected by high operating temperatures, therefore, maintaining low temperatures can prolong the lifespan and power of the motor.
Achieving High Energy Intensive Batteries
High energy density lithium-ion batteries enable electric vehicles to increase payload capacity and range, while reducing costs - a key factor in the sustained growth of the electric vehicle market.
However, cooling these batteries has become a powerful barrier to further increase their power.
The disadvantage of high-energy density lithium-ion batteries is that they generate more heat on the same surface area as the previous generation batteries, and cooling must be more efficient and uniform. The traditional s-shaped thermal design is not sufficient, so Awind will use multi channel vacuum brazing water cooling plate heatsink. The water cooling plate heat sink has multiple flow channels, making it more efficient in heat dissipation and more uniform in heat dissipation area.
Reduce costs by reducing weight
Another important factor in cost is weight. The electric vehicle industry is addressing this challenge by reducing the weight and volume of battery packs themselves.
Another option is to reduce the mass of the cooling radiator, which also takes up a considerable amount of volume and weight.
Awind's vacuum brazing water cold radiator plate has a lightweight design and maintains its high thermal efficiency. Very suitable for battery usage in new energy electric vehicles
Reducing the weight in the cooling radiator has an additional advantage of requiring fewer materials for production. Therefore, it is not only lighter, but also cheaper.
