The reliable performance and long-term heat dissipation of CNC Radiator for Electric Vehicle Battery depend on the strict selection and scientific matching of materials. The heat dissipation scenario of electric vehicle batteries is special, which needs to withstand complex working conditions such as high and low temperatures, vibration and humidity. The materials not only need to meet the requirements of CNC precision processing, but also have excellent thermal conductivity, corrosion resistance, structural strength and lightweight characteristics. High-adaptability raw materials are carefully selected to balance performance and safety, providing a solid guarantee for the stable operation of electric vehicle batteries. The total materials meet high-end industry standards and are suitable for various new energy vehicle battery systems.
The core material of the radiator body is 6063 aviation-grade aluminum alloy. As the preferred material for electric vehicle battery radiators, its density is only 2.7g/cm³, which has significant lightweight advantages, effectively reducing vehicle energy consumption. At the same time, its tensile strength is more than 205MPa, with excellent toughness. After CNC precision processing, it is not easy to deform or crack, adapting to the narrow installation space of the battery compartment. The thermal conductivity of this material is as high as 201W/(m·K), which can quickly conduct the heat generated by the battery during operation. Combined with the fins formed by precision CNC milling, the heat dissipation efficiency is further improved to meet the constant temperature demand of the battery.
The core heat-conducting component is oxygen-free copper heat pipe with a purity of 99.99%, no impurities and no pores. Its thermal conductivity is as high as 386W/(m·K), 1.9 times that of aluminum alloy, which can quickly conduct the core heat of the battery to the radiator body. The inner wall of the heat pipe is designed with a capillary structure, injected with high-efficiency heat-conducting medium, and subjected to vacuum packaging treatment to prevent medium leakage. It is suitable for the long-term bumpy and high-low temperature alternating working conditions of electric vehicles, ensuring stable and long-lasting heat conduction performance and avoiding battery damage due to local overheating.
Sealing and protection materials balance practicality and durability. The interface seal adopts high-temperature and aging-resistant silicone rubber sealing ring, which can withstand extreme temperatures of -40℃~120℃, with excellent sealing performance, preventing dust and moisture from entering the radiator and avoiding corrosion of components. The surface treatment adopts hard anodizing process to form a dense oxide film with a thickness of 10-15μm, which greatly improves corrosion resistance and wear resistance, and enhances thermal conductivity. It is suitable for complex environments such as outdoor and humidity, extending the service life of the radiator.
Auxiliary materials are also strict. The fixed bracket is made of high-strength 304 stainless steel, which is rust-proof and corrosion-resistant, ensuring that the radiator is firmly installed and resists vibration during vehicle operation; the thermal interface adopts high thermal conductivity silicone pad with a thermal conductivity of 1.5W/(m·K), which closely fits the battery and the radiator, reducing heat conduction loss. All materials have undergone strict quality inspection, complying with new energy vehicle industry standards, realizing the perfect combination of materials and processes, and providing efficient, stable and safe heat dissipation support for electric vehicle batteries.
