Aluminum Extruded Radiator Power Radiator

Product introduction

In modern electronic equipment, as a key component to provide stable power, the reliability of its performance is very important. However, the power supply will inevitably generate heat during the working process, if it cannot effectively dissipate heat, it will seriously affect the efficiency, stability and service life of the power supply. With its unique advantages, aluminum extruded radiator has become one of the mainstream solutions in the field of power cooling.

The heat dissipation principle of aluminum extruded radiators is based on the basic heat transfer mechanism of heat conduction, heat convection and heat radiation. Aluminum has a high thermal conductivity and can quickly conduct the heat generated by the power supply element to various parts of the radiator. Its extruded structural design increases the contact area with the air, and when the air flows through the radiator surface, the heat is passed to the air through the heat pair, raising the air temperature and taking away the heat. At the same time, the surface of the radiator will also emit a small amount of heat to the surrounding environment in the form of thermal radiation, so as to achieve efficient heat dissipation, ensure that the internal temperature of the power supply is maintained within a reasonable range, and ensure the stable operation of the power supply.

Structural characteristics

Fin structure: Aluminum extruded radiators usually have a carefully designed fin structure, which is closely arranged and parallel to each other, greatly increasing the contact area between the radiator and the air, and improving the heat exchange efficiency. Fin parameters such as shape, thickness, spacing and height are optimized to balance heat dissipation performance with manufacturing process requirements to ensure optimal heat dissipation in a limited space.

Integrated molding: The use of aluminum extrusion process can achieve the integrated molding of the radiator, reducing the connection part, reducing the thermal resistance, and improving the overall structural strength and reliability of the radiator. This integrated design also makes the appearance of the radiator more structured, easy to install and cooperate with other power components, while also helping to improve production efficiency and reduce manufacturing costs.

A variety of shapes and sizes: In order to meet the needs of different power supply designs, aluminum extruders can be processed into various shapes and sizes, such as flat, U-shaped, L-shaped, etc., which can flexibly adapt to the complex spatial layout inside the power supply and achieve a tight fit with the heating element to ensure that the heat can be quickly and effectively transmitted to the radiator for distribution.

Production process

Raw material preparation: The selection of high-quality aluminum alloy bars as raw materials, according to the performance requirements of the radiator to choose the appropriate aluminum alloy grade, its composition and purity have an important impact on the thermal conductivity of the radiator, mechanical properties and processing properties.

Heating and extrusion: the aluminum alloy bar is heated to the appropriate temperature range, so that it has good plasticity, and then a huge pressure is applied through the extrusion press, so that the aluminum material is extruded in the cavity of the mold to form a radiator blank with a specific shape and size. Parameters such as temperature, pressure and extrusion speed during the extrusion process need to be strictly controlled to ensure the dimensional accuracy of the radiator and the uniformity of the internal organizational structure.

Cutting and processing: The heat sink blank after extrusion is cut according to the actual size requirements to remove excess parts. Further machining, such as drilling, tapping, milling, etc. is then carried out to meet the needs of the power installation, such as the corresponding hole positions and threads for fixing screws, inserting electronic components, etc.

Surface treatment: In order to improve the corrosion resistance and heat dissipation efficiency of the radiator, it is usually subjected to surface treatment. Common surface treatment methods include anodic oxidation, electrophoretic coating and passivation treatment. The anodic oxidation can form a dense oxide film on the surface of the radiator to enhance its corrosion resistance, and the porous structure of the oxide film helps to increase the heat dissipation area. Electrophoretic coating can make the radiator obtain beautiful, uniform and good protective coating. Passivation treatment can form a passivation film on the surface, further improve the corrosion resistance, and prevent the heat sink from being damaged by oxidation and corrosion during use.

Performance advantage

Efficient heat dissipation performance: The efficient heat dissipation capacity of the aluminum extruded radiator can effectively reduce the temperature inside the power supply and improve the conversion efficiency and reliability of the power supply. Through the optimized fin structure and good heat conduction performance, it can quickly dissipate heat, avoid problems such as the performance decline of electronic components caused by overheating, shortened life and even failure damage, so as to ensure the stable operation of the power system and extend the service life of the power supply.

Good mechanical properties: Aluminum alloy materials have high strength and hardness, making aluminum heat sink can withstand certain mechanical stress and vibration, and maintain the integrity and stability of the structure during the transportation, installation and use of the power supply. This is particularly important for some power equipment working in harsh environments, such as industrial control power supplies, communication base station power supplies, etc., to ensure that the radiator works normally under long-term complex conditions, providing reliable heat dissipation protection for the power supply.

Lightweight design: The density of aluminum is relatively low, which makes the aluminum extrusion radiator achieve the lightweight design goal on the premise of ensuring the heat dissipation performance. This has significant advantages for some application scenarios that have strict requirements for weight, such as portable electronic equipment power supplies, aerospace power supplies, etc., which not only helps to reduce the weight of the entire power system, easy to carry and install, but also reduces the energy consumption of the equipment and improves energy efficiency.
