Advancements in Thermal Conductivity and Flame Retardancy of RPU Foam for Water-Cooled Plate Supports in NEVs

Efficient heat management is crucial for optimal performance and safety in new energy vehicles (NEVs). Rigid polyurethane (RPU) foam has emerged as a promising material for water-cooled plate supports in NEVs due to its lightweight nature and thermal insulation properties. This article explores the key aspects of RPU foam, including its thermal conductivity, flame retardant properties, and its role in the thermal system of NEVs.

Enhancing Thermal Conductivity of RPU Foam:

The thermal conductivity of RPU foam plays a vital role in its application as a water-cooled plate support. Typically, pure RPU foam exhibits a thermal conductivity of 0.0235 W/(m‧K). However, by incorporating specific additives or composite materials, the thermal conductivity of RPU foam can be optimized to improve heat transfer efficiency. Manipulating the thermal conductivity of RPU foam allows for the design of effective cooling systems in NEVs, facilitating the efficient dissipation of heat generated by the batteries.

Improving Flame Retardant Properties of RPU Foam:

Fire safety is of utmost importance in NEVs, making the flame retardant properties of RPU foam crucial. Rigorous testing methods such as the limiting oxygen index (LOI) and UL-94 burning tests evaluate the flammability performance of RPU foam. By incorporating suitable flame retardant additives, the fire resistance of RPU foam can be significantly enhanced. This ensures the safety of water-cooled plate supports and the overall thermal system in NEVs.

Role of RPU Foam in the Thermal System:

RPU foam plays a key role in the thermal system of NEVs, particularly in water-cooled plate supports. These supports efficiently absorb and transfer heat generated by the batteries, ensuring effective cooling. The lightweight nature of RPU foam helps reduce the vehicle's overall weight while providing excellent thermal insulation. Through optimizing thermal conductivity and incorporating flame retardant properties, RPU foam enhances the performance and safety of the thermal system in NEVs.

Conclusion:

Utilizing RPU foam for water-cooled plate supports in NEVs offers significant advantages in terms of thermal management. By optimizing thermal conductivity and incorporating flame retardant properties, RPU foam enables efficient heat dissipation while ensuring fire safety. The lightweight nature of RPU foam further contributes to the overall performance and energy efficiency of NEVs. Focusing on these key aspects, the development of RPU foam-based water-cooled plate supports can greatly enhance the thermal system in NEVs, promoting safer and more efficient electric vehicles.
