Round extruded aluminum heatsink:

Huizhou Weihua Technology specializes in the production of aluminum profile computer CPU heatsink, car power amplifier heatsink, aluminum profile LED sunflower heatsink, aluminum profile electronic heatsink and other products. It is a professional extruded aluminum heatsink manufacturer.

We will briefly introduce the characteristics, types and advantages of the heatsinks below.

Name CPU heatsink
Size 102X28mm
Material Aluminum
Process advantages Material cutting+Die cutting+CNC+Deburr+Anodized+Full inspection+Package
Application Computer CPU heatsink



The furnace heats the aluminum ingot at high temperature and extrudes the aluminum rod, and then injects the aluminum rod into the mold with grooves to make the preliminary embryo of the heatsink, and then performs post-processing <CNC, trimming, drilling, tapping, polishing, Wire drawing, other surface treatments (sandblasting anodizing, etc.), riveting pins, and packaging>

Types of heatsink:

1. Cast iron heatsink

Cast iron heatsink will gradually be eliminated by the market because of its low pressure, large volume, rough shape, high production energy consumption and many insurmountable disadvantages.

2. Steel heatsink

At present, steel heatsink are mainly divided into two types: plate type and column type. Especially the steel column heatsink, with its rich colors and beautiful appearance, has won the love of many consumers.

3. Aluminum heatsink

Aluminum heatsink mainly include high-pressure cast aluminum and stretched aluminum alloy welding.

The main advantages are:

Aluminum heatsink has good thermal conductivity, high pressure resistance and high metal thermal strength. Large heat dissipation, fast heat dissipation, and efficiency are the biggest characteristics of aluminum heatsink. The exterior is electrostatically sprayed, beautiful in color and decorative. The general evaluation is: Comprehensive production does not pollute the environment or water quality. Beautiful and generous, occupying little room space, environmental protection and energy saving. It is in line with the "lightweight, efficient, environmentally friendly, and energy-saving" requirements for the development of heatsink in my country.

In terms of making heatsink, aluminum profiles are the best choice for making heatsink. Whether it is energy saving, material saving, decoration, price, weight, etc., all have advantages. The heat dissipation of steel pipe is definitely not as good as that of aluminum. Therefore, heatsink made of aluminum are superior to heatsink made of other materials in any respect.

In the aluminum extruded heatsink, the sun flower heatsink is the outstanding product.

Sunflower heatsink refers to a heatsink designed in a radioactive arrangement. It is made into a sunflower shape, which can increase the contact between the heatsink and the air. The heat diffuses through the center to the heatsink on the four sides, and its shape makes it more uniform and smooth It accepts the airflow and takes away the heat more evenly. This heat dissipation effect is very fast and the effect is quite obvious. It is very suitable for current component heat dissipation. Sunflower aluminum heatsink is widely used in new energy, inverter, power electronics, communication equipment and other fields.
