Types and Grades of Aluminum Materials Used in Radiators
3003 Aluminum Plate
This is a common aluminum-manganese alloy that is widely used in electric vehicle radiators. 3003 aluminum plate has good forming and processing properties and can be easily processed into various shapes required for radiators, such as flat water pipes and heat sinks with corrugated fins. It also has good corrosion resistance, can maintain stable performance in complex working environments, and extend the service life of the radiator. In addition, it has moderate strength, which is sufficient to meet the structural requirements of the radiator under normal working conditions.
3003 + 4045 Brazing Plate
This composite plate is composed of 3003 aluminum alloy and 4045 aluminum alloy. 3003 aluminum alloy provides basic properties such as good forming processing performance and corrosion resistance, while 4045 aluminum alloy plays an important role in the brazing process. As a brazing filler material, 4045 aluminum alloy has good fluidity and wettability, which can ensure good bonding during the brazing process. This composite plate is widely used in heat dissipation components such as water cooling plates of electric vehicles, which helps to improve the overall thermal conductivity of the heat dissipation system.
Heat-free Aluminum Alloy (such as the product independently developed by Changchun Longda, a subsidiary of Lizhong Group)
This new type of heat-free aluminum alloy has also begun to emerge in the manufacture of electric vehicle radiators. It can effectively improve the lightweight level of electric vehicles, thereby improving the performance and energy efficiency of electric vehicles. In the manufacture of radiators, it not only retains the good thermal conductivity of aluminum materials but also simplifies the production process and reduces production costs through the characteristics of heat-free treatment.
Combination of Aluminum Materials and Radiator Design
In addition to the characteristics of aluminum materials themselves, its close combination with the design of radiators is also the key to improving heat dissipation efficiency. For example, in the design of some radiators, aluminum water pipes adopt a planar structure and are equipped with corrugated fins between adjacent cooling pipes. This design takes advantage of the good plasticity of aluminum materials and improves the heat dissipation effect by increasing the heat dissipation area. For example, in the design of some integrated radiators, aluminum materials are used to manufacture heat dissipation cores with different functions, such as engine heat dissipation cores, motor heat dissipation cores, etc. Through reasonable layout and structural design, these aluminum heat dissipation cores can effectively reduce the volume and space occupancy while ensuring ventilation and heat dissipation, reduce the overall weight, and facilitate assembly in the limited space of electric vehicles.
Aluminum materials have an irreplaceable position in the material selection of electric vehicle radiators. Different types and grades of aluminum materials are combined with ingenious designs to provide efficient, reliable and lightweight solutions for electric vehicle cooling systems.
In general, although electric vehicles do not have traditional fuel engines, they also need radiators because key components such as batteries and motors generate heat during operation. These radiators are an important part of ensuring the performance, safety and service life of electric vehicles. With the continuous development of electric vehicle technology, radiator technology will also continue to improve to meet higher heat dissipation requirements.
