As a heat dissipation tool with high heat dissipation efficiency, aluminum profile radiators have been widely used in electronics, electrical appliances, and lighting industries. However, different aluminum profile radiator manufacturers have mastered different technologies and different production standards, and the heat dissipation effect of aluminum profile radiators is also graded.
So how to choose a good aluminum profile? Let me introduce you.
1. Look at the degree of oxidation: when choosing and buying, you can scrape on the surface of the contour to see if the oxide film on its surface can be wiped off.
2. Colorimetry: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase. Under normal circumstances, the cross-sectional color of ordinary aluminum alloy profiles is silver-white and the texture is uniform. If the color is dark, you can conclude that it is forged from recycled aluminum or scrap aluminum.
3. Flatness: Check the surface of aluminum alloy profiles, there should be no depressions or protrusions. The surface of aluminum profiles processed by regular manufacturers is smooth and bright. If it is a small workshop caused by machinery or raw materials, the surface of the profile will be slightly uneven. The heat sink synthesized from this aluminum alloy profile is easy to oxidize and deform in the later period.
4. Strength: When purchasing, you can bend the profile moderately by hand. If you do not bend the profile, you can draw the conclusion that the strength of the aluminum profile is unqualified. In addition, the strength of the profile is not as hard as possible. Aluminum has certain toughness and non-rigidity. Material, use this feature to forge into different shapes very well.
Through the above methods, you can basically determine the quality of aluminum profiles. To produce good heat dissipation, in addition to the production process, choose an excellent aluminum profile supplier, such as Hefei Analu International Trading Co., Ltd., you can do more with less. To achieve a multiplier effect.
