The relationship between the appearance and performance of electronic heat sink fins
In order to popularize the performance of electronic heat sinks, this type of heat sink is usually designed with a fin shape with stronger heat dissipation performance, which is formed by bending a thin aluminum plate, occupying a larger nominal volume, and not only can spread in a larger area. Heat, but also greatly increases the area of the opposite door between the heat dissipation panel and the atmosphere, so there is a corresponding relationship between them. Then the radiator can dissipate the heat in a shorter time. The meticulous design makes the heat dissipation power of the radiator stronger, and the detailed solution allows the radiator to meet the heat dissipation needs of more electronic products.
Regarding the radiator, to attract as much heat generated by the electronic power amplifier as possible in a temporary period, it must have a higher heat transfer coefficient. The material of this radiator of Chicco chooses 6063 aluminum alloy, and the thermal conductivity is up to 201W/mK. Compared with normal non-metallic thermal materials, the use of aluminum alloy is not only exquisite in appearance and affordable, but also has strong thermal conductivity and can meet the heat dissipation needs of various electronic products. The extremely high-purity aluminum alloy makes this radiator extremely resistant to low temperature and corrosion, so it has a longer service life.
The size-related performance of aluminum is relatively more, but there are still more small-size aluminum, and the amount is also relatively large; So far recently, there have been a lot of searches for medium-sized aluminum cutting machines on the Internet, and Deng came to the conclusion DS -A400 aluminum cutting machine belongs to the range of medium-sized aluminum cutting. The cutting size is less than 110*270mm, so there are really many such aluminum materials. In conclusion, it is important to affect the next 9 major aluminum processing industries:
Extrusion heat: Magnesium alloy extrusion heat is slightly lower. To prevent magnesium ingots from extinguishing, the minimum allowable heating temperature for magnesium alloys of various groups is 470℃; while the maximum heating heat for aluminum alloys can reach 550℃.
Last size correlation: Magnesium alloy hot-extruded material has a larger expansion rate than aluminum alloy, and the deformation resistance of the last is greater. The last is designed to accept greater extrusion force and do everything possible to reduce the size of non-metallic extrusion. Deformation resistance.
Aluminum alloy is considered to be the hottest radiator material on the market today, among which the relatively high-quality ones are aluminum alloy 6063 and 6061. Although the heat dissipation performance is not as good as copper, the heat dissipation coefficient can reach 201W/mK, which can completely meet the needs of electronic products for heat dissipation. The light weight, easy processing, attractive appearance, and affordable price make it particularly widely used.
