Detailed introduction

铝合金电子散热器


The commonly used aluminum alloy electronic radiator bottom surface treatment process includes:

The

First, the drawing process is also the most used bottom treatment process. The use of a tool with a certain degree of roughness and hardness on the surface during the drawing process, such as sandpaper, squeegee, etc., is used to perform one-way, repeated, or rotational friction on the surface of the object to be treated, and the surface of the tool is rubbed to remove the treated surface. The protrusions; of course, flattening the protrusions will also cause scratches on the originally flat surface. Therefore, a coarse-to-fine, step-by-step process should be used to gradually reduce the roughness of the treated surface.

Second, the disk milling process refers to cutting the surface of the electronic heat sink through a high-speed rotating tool after the bottom of the electronic heat sink is fixed. The tool is always rotated in the same plane, so the cut bottom surface is very smooth. As with the wire drawing process, the finer the tool used in the disk milling process, the higher the flatness of the cut bottom surface. The milling and milling process has a relatively high manufacturing cost, but relatively only two or three processes are required for relative drawing, which is relatively time-saving and has an ideal effect.

Third, the CNC machine tool used in the bottom of the heat sink leveling process is still the main process used to mill. However, unlike conventional disk milling, the tools of the CNC milling machine can accurately control the relative distance between the heat sink and the heat sink. After the tool contacts the bottom surface of the heat sink, the two horizontally move relative to each other, and the unprocessed portion left in the tool gap in the conventional disk milling can be cut to achieve a complete planar effect. No subsequent processing is required to obtain the general effect of the mirror. Flatness can be less than 0.001mm.

The

Fourth, in addition to the above, there are other processes for the bottom treatment of electronic radiators, such as polishing, polishing processing is more for the aesthetic considerations of the electronic radiator, the flatness of the electronic radiator bottom improved, quality performance better.

The

As we said earlier, no matter how the bottom of the aluminum alloy electronic radiator is handled, this mechanical process cannot make a completely standard flat surface, and the gaps or gaps between the CPU and the electronic radiator are always inevitable. The air present in these gaps has a great influence on the conduction capacity of the electronic radiator. It is known that the thermal resistance value of air is high, so it is necessary to use other substances to reduce the thermal resistance, otherwise the conduction performance of the electronic radiator Will be greatly reduced, and even can not play a role. This is the origin of the heat transfer medium. Its role is to fill the large and small gap between the heat source such as the CPU and the electronic heat sink, and increase the contact area between the heat source and the heat sink.
