MATERIALS FOR ALUMINIUM RADIATOR
These are commonly used aluminum alloy materials with good plasticity, suitable for extrusion processes, and can be used to manufacture heat sinks in various shapes.
In some high-performance heat sinks, copper-aluminum alloys may be used, using the high thermal conductivity of copper and the lightweight advantages of aluminum to achieve better heat dissipation
TYPES OF SURFACE TREATMENT PROCESSES
There are a wide variety of surface treatment processes designed to enhance the performance of a part, such as increasing corrosion resistance, wear resistance, aesthetics, or other specific features.
Electroplating
Using the principle of electrolysis to deposit a layer of metal plating on a metal surface, such as zinc, copper, nickel, chromium, etc., to enhance corrosion resistance, wear resistance or decorative properties.
Anodic Oxidation
Especially for aluminium and aluminium alloys, it generates a dense film of aluminium oxide by electrochemical reaction, which improves corrosion and abrasion resistance, and can also be coloured.
Wire drawing
By forming a regular fine line texture on the surface of the metal, thus giving the product a unique texture and visual effect.
Sandblasting
The use of a high-pressure jet of abrasive material (e.g. grit) to remove surface impurities and provide a uniform roughness that facilitates the adhesion of subsequent coatings.
DLC Coating
An amorphous thin film of carbon, similar in structure and properties to natural diamond, but without the crystal structure, DLC coatings are widely used in industry due to their excellent properties.
Marking
Although not a surface coating treatment, laser marking can leave a permanent mark on a metal surface for identification, tracking or decorative purposes.

WORKING PRINCIPLE, ADVANTAGES AND APPLICATIONS
1. What is an aluminum radiator?
Aluminum radiator is a device specially designed for heat dissipation, which utilizes the excellent thermal conductivity of aluminum material to quickly remove heat from the heat source and dissipate it into the surrounding environment. Aluminum radiators are widely used in many fields, especially in electronic devices, automobiles, industrial machinery, household appliances, etc., because they can effectively control the heat generated during equipment operation, avoiding performance degradation or damage caused by overheating.
The basic structure of an aluminum radiator typically includes a bottom plate (or heat sink) in contact with a heat source and a series of heat dissipation fins (or fins). The function of the bottom plate is to receive and distribute heat from the heat source, while the heat sink increases the surface area of the radiator in contact with the air, accelerating the dissipation of heat into the air. In some high-performance aluminum heat sinks, heat pipe technology may also be used, where the working fluid inside the heat pipe can quickly transfer a large amount of heat during evaporation and condensation, significantly improving heat dissipation efficiency.
2. The characteristics of aluminum radiators include:
Lightweight
Aluminum is a lightweight metal, which means that aluminum heat sinks can maintain relatively low weight while ensuring heat dissipation performance, which is particularly important for portable electronic devices and vehicles.
Plasticity
Aluminum can be easily processed into various shapes, such as fins, tubes, flat shapes, etc. The structure of the heat sink can be designed according to different application requirements to optimize the heat dissipation effect.
High thermal conductivity
Aluminum has good thermal conductivity, which can quickly transfer heat from the heat source to the surface of the radiator, thereby accelerating the dissipation of heat.
Corrosion resistance
The aluminum surface is prone to forming a dense layer of aluminum oxide film, which can protect the radiator from external environmental erosion and extend its service life.
3. Application scope:
There are various types of aluminum radiators, including sunflower aluminum profile radiators, extruded profile radiators, and cast radiators. According to specific application scenarios and requirements, the most suitable type and design of radiator can be selected.
Automotive industry
Cooling systems for automotive engines, thermal management of electric vehicle battery packs.
Electronic devices
Used for thermal management of electronic devices such as computers, servers, LED lighting, etc.
Industrial equipment
Used for heat dissipation in industrial electronic devices such as frequency converters, inverters, and power modules.
Air conditioning and heating system
Used as radiators to provide indoor heating through hot water circulation.
A During installation, attention should be paid to the directionality of the heat sink to ensure that the direction of the heat sink is consistent with the direction of the airflow; Avoid deformation caused by excessive tightening; Use thermal paste or other thermal conductive materials to improve heat transfer efficiency.
Aluminum radiators may encounter problems such as poor heat dissipation, surface oxidation, leakage, etc. These issues may be related to unreasonable design, improper material selection, or manufacturing process problems.
A Anodizing can form a dense oxide film, improving the corrosion resistance and wear resistance of the heat sink, as well as enhancing the surface insulation.
A 1.Scratches and scuffs: scratches or scuffs may occur on the surface of aluminium profiles during processing, handling or installation. 2.Porosity: During casting or welding, gas fails to escape completely and holes are formed on the surface or inside. 3.Cracks: Uneven distribution of stress within the material or improper processing may lead to cracks on the surface. 4.Oxide film defects: after anodic oxidation treatment of aluminium profiles, if the treatment process is not appropriate, it may lead to uneven oxide film or defects. 5.Colour difference: Improper operation during surface treatment, such as spraying or dyeing, may lead to inconsistent colour. 6.Deformation: Processing may cause deformation of the radiator if the temperature is not properly controlled or the mechanical stress is too great.
