Aluminium Extruded Section Heat Sink

Product introduction

The working principle of the aluminum extruded heat sink is based on the excellent thermal conductivity of the aluminum alloy. Aluminum alloy has a high thermal conductivity, can quickly transfer heat from the heat source to the various parts of the radiator, and then through the heat exchange between the surface of the radiator and the surrounding air, the heat is dissipated to the environment. Compared with other heat dissipation materials, aluminum extruded heat sinks have many significant advantages. First of all, the density of aluminum alloy is relatively low, which makes the radiator to ensure the heat dissipation performance at the same time, with a light weight, for the weight has strict requirements of electronic equipment, such as laptops, mobile power supplies, aluminum extrusion radiator is the ideal choice. Secondly, the processing technology of aluminum alloy is mature, and through extrusion molding technology, a variety of complex shapes and structures can be manufactured to meet the specific heat dissipation needs of different equipment, and can achieve large-scale and efficient production and effectively reduce production costs. In addition, aluminum alloy has good corrosion resistance and oxidation resistance, and can work stably in complex environmental conditions for a long time to ensure the service life of the radiator.

Product features and performance parameters

High efficiency heat dissipation

The fins of the aluminum extruded heat sink are usually designed as a densely arranged sheet structure, which greatly increases the heat dissipation area and improves the heat exchange efficiency. According to the actual test, under the same heat dissipation conditions, the heat dissipation efficiency of aluminum extruded heat sink is higher than that of traditional cast iron heat sink, which can effectively reduce the working temperature of the device. For example, in the heat dissipation application of a high-performance CPU, the use of aluminum extruded heat sink can control the chip temperature within the safe working range to ensure that the CPU performance is not affected by overheating. Stable operation.

Diversified structural design

Aluminum extruded heat sinks can be designed in a variety of shapes and sizes according to different heat dissipation needs and installation space. Whether it is flat, U-shaped, L-shaped or complex special-shaped structures, it can be precisely manufactured through the extrusion process. This diversified design enables the radiator to closely fit the heat source, achieve better heat conduction effect, and also facilitate installation and layout in a limited space, meeting the development trend of miniaturization and integration of electronic equipment.

Reliable quality stability

In the production process, the aluminum extrusion radiator adopts advanced extrusion equipment and precision mold to ensure high dimensional accuracy and good surface quality. At the same time, the strict quality control system monitors the composition of raw materials, extrusion process parameters, heat treatment process, etc., to ensure that each radiator has a consistent heat dissipation performance and mechanical properties, effectively avoid heat dissipation failures caused by quality problems, and provide reliable guarantee for the stable operation of electronic equipment.

Good fit

Aluminum extruded heat sinks can be easily combined with other cooling components, such as fans and heat pipes, to further improve the heat dissipation effect. By optimizing the matching structure of the radiator and the fan, an efficient air duct can be formed to accelerate the air flow and enhance the heat dissipation capacity. For example, in some high-end graphics card cooling systems, the combination of aluminum extrusion heat sink and high-speed fan can quickly take away a lot of heat generated by the GPU during high load operation, ensure the stable work of the graphics card, and meet the heat dissipation requirements of high-performance graphics cards for gamers and professional graphics processing users.
