PRODUCT Description

Aluminum led heatsink has the advantages of light weight, beautiful and durable, high heat dissipation rate, good shapeability, etc., and has been widely used in air conditioners, coolers and radiators. In my country, the use of aluminum profiles for radiators is becoming more and more popular, and aluminum extrusion molding is the main form. This is because the aluminum extrusion molding has a good size consistency, a short production cycle and a relatively low cost. In the extrusion production process of aluminum led heatsink, the extrusion die is of great significance to realize the entire extrusion process. Extrusion die is the basic tool to ensure that the product is formed and has the correct shape, size and accuracy. Reasonable extrusion tool structure, shape and size can control the internal structure and mechanical properties of the product to a certain extent, especially in terms of controlling the weld structure and mechanical properties of hollow aluminum products, the size and shape of the shunt hole and Its distribution position, the shape and size of the welding cavity, and the structure of the mold core play a decisive role.


Aluminum led heatsink structure analysis


Figure 1 is a cross-sectional view of an aluminum alloy profile for aluminum led heatsink lamp radiator. It can be seen from the figure that the aluminum led heatsink lamp radiator uses an aluminum alloy extruded hollow profile, which is characterized by a large circumscribed circle, a complex cross-sectional shape, a large cross-section, and an overall length It is 340mm and the height is 100mm; the aluminum led heatsink teeth are thin, the cantilever is long, the tongue ratio at the cantilever is large, and the tongue ratio can be as large as 8. However, the distance between the teeth of the heat sink is small, and there are dangerous sections between the teeth. After the force is applied, eccentric teeth and broken teeth are prone to cause the mold to be scrapped; secondly, the wall thickness of the aluminum led heatsink profile section is very different, especially the thickness of the bottom plate at the root of the section is thicker (thickness up to 28mm), and the thickness of the aluminum led heatsink teeth is thinner It is only 2mm, and the wall thickness ratio is as high as 14, resulting in extremely uneven flow rates of aluminum extrusion, and increasing the fracture coefficient of dangerous sections. Therefore, it brings great difficulty to the mold design, manufacture and production of the aluminum radiator profile. If the design of the extrusion die is unreasonable, it is easy to cause defects such as eccentric teeth, broken teeth, twisting, waves, bending and cracks of the die during extrusion, so the reasonable design of the extrusion die is the profile of the aluminum LED lamp heat sink. The decisive factor to achieve normal extrusion.
