High Tooth Aluminum Extruded Aluminum Radiator

Product introduction

In today's electronic equipment performance continues to improve, the heat dissipation problem has become one of the key factors to ensure the stable operation of equipment and extend the service life. With its excellent heat dissipation performance, lightweight design and good processing process adaptability, the high-tooth aluminum extruded aluminum radiator has been widely used in many fields, and has become one of the popular choices in the field of electronic heat dissipation.

The heat dissipation principle of high-tooth aluminum extruded heat sink is based on three basic heat transfer modes: heat conduction, heat convection and heat radiation. As an excellent thermal conductivity material, aluminum has a high thermal conductivity and can quickly conduct heat from the heat source to various parts of the radiator.

Its unique high-toothed structure design greatly increases the contact area between the radiator and the air. As air flows over the surface of the radiator, heat is transferred to the air by means of thermal convection, raising the temperature of the air and carrying away the heat. At the same time, the radiator surface will also emit a small amount of heat to the surrounding environment in the form of thermal radiation. Through the synergistic effect of these three heat transfer methods, the high-tooth aluminum extruded aluminum radiator can effectively dissipate the heat generated by the heating element and maintain the equipment in the appropriate operating temperature range.

Product features

High efficiency heat dissipation

The high tooth structure makes the heat dissipation area of the radiator significantly increase compared with the ordinary flat radiator, which can transfer heat to the surrounding environment more efficiently. Under the same heat dissipation conditions, the high tooth aluminum extrusion aluminum radiator can reduce the temperature of the heating element faster, effectively improve the reliability and stability of the equipment, especially for high power, high heat density of electronic equipment heat dissipation, such as computer CPU, GPU, power electronic devices, etc.

Lightweight design

Aluminum extruded aluminum radiator is made of aluminum alloy material, aluminum alloy has the characteristics of low density and high strength, and the lightweight design of the radiator is realized under the premise of ensuring the heat dissipation performance. This is of great significance for applications that have strict requirements for weight, such as aerospace, portable electronic equipment, etc., which not only helps to reduce the weight of the overall equipment, but also facilitates the installation, transportation and operation of the equipment.

Good mechanical properties

Aluminum alloy has good machining performance, easy to cut, drilling, tapping and other processing operations, can be easily customized according to the needs of actual application design and installation. At the same time, the aluminum alloy material has a certain strength and hardness, which can maintain the structural integrity of the radiator in a complex working environment, resist external impact and vibration, and ensure the long-term stable operation of the heat dissipation system.

Corrosion resistance

After proper surface treatment, the high-tooth aluminum extruded aluminum radiator has good corrosion resistance and can work normally under harsh environmental conditions such as humidity, acid and alkali. Common surface treatment methods include anodic oxidation, electrophoretic coating, etc. These treatment processes can not only improve the corrosion resistance of the radiator, but also improve its appearance quality to meet the individual needs of different customers for products.

Production process

Aluminum rod extrusion

First of all, the aluminum alloy bar that meets the quality standard is selected as the raw material, and it is heated to the appropriate temperature and then put into the mold of the extrusion press. Through the strong pressure of the extruder, the aluminum rod is plastic deformed under the constraint of the mold, and the high-toothed aluminum profiles with specific shapes and sizes are extruded. In the extrusion process, the design and manufacturing accuracy of the mold plays a key role in the tooth structure, dimensional accuracy and surface quality of the radiator, which needs to be carefully designed and processed according to the specific requirements of the product.

Cutting and machining

The extruded aluminum profile is cut according to the actual length needed, and then further mechanical processing, such as drilling, milling, tapping, etc., is carried out to meet different installation and connection requirements. In the processing process, it is necessary to use high-precision processing equipment and advanced processing technology to ensure that the dimensions of each part of the radiator are accurate and the surface is smooth, so as to avoid problems such as reduced heat dissipation performance or inconvenient installation caused by processing errors.

Surface treatment

In order to improve the corrosion resistance and heat dissipation performance of the radiator, it is usually treated on the surface. Anodizing is a common surface treatment method, by forming a dense oxide film on the surface of aluminum profiles in the electrolyte, it can not only enhance its corrosion resistance, but also improve the hardness and wear resistance of the surface, while the porous structure of the oxide film helps to improve the heat dissipation efficiency of the radiator. Electrophoretic coating is under the action of electric field, the coating is uniformly deposited on the surface of the radiator to form a layer of beautiful and corrosion-resistant coating, which is suitable for applications with high appearance quality requirements.
