Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of radiator, concretely is magnesium alloy lightweight alloy radiator. BACKGROUND

[0002] The magnesium alloy lightweight alloy radiator is a radiator made of magnesium alloy material, which is widely used in fields requiring efficient heat dissipation, such as electronic products, automobiles, aerospace, etc. Magnesium alloy has high strength, good thermal conductivity and good processing performance, and because of its low density, the radiator produced by magnesium alloy has the effect of lightweight, which has a significant advantage in the design and manufacture of the radiator.

[0003] The prior art has the following disadvantages: In the prior art with application number 201320437312.X, a magnesium alloy LED mining lamp radiator profile is proposed, which includes a central ring column and a plurality of heat dissipation fins integrated with the central ring column. The central ring column has a central hole, and the inner diameter of the central ring column is 10-20mm and the outer diameter is 60-70mm. The outer diameter of the profile is 170-190mm. The plurality of heat dissipation fins are distributed radially on the outer periphery of the central ring column. The effect of the utility model is that according to the thermal plasticity parameter characteristics of magnesium alloy, the outer diameter of the central ring column of the profile, i.e. the diameter of the root of the radiator fin, is increased, and at the same time the inner diameter of the central ring column is reduced. Compared with aluminum alloy, the weight is reduced and the heat dissipation performance is comparable. If the structure is replaced with aluminum alloy, the weight and cost will increase. It is beneficial to the realization of the structure of magnesium alloy. The LED mining lamp magnesium alloy radiator made of the profile realizes lightweight, good heat dissipation and low cost.

[0004] The heat dissipation fins in the above-mentioned device are integrally formed with the central ring column, and the overall radiator is a whole. Since magnesium alloy itself has poor corrosion resistance, especially in humid, salt spray or strong acid and strong alkali environments, the current method is to enhance the corrosion resistance of the magnesium alloy surface by surface treatment, but only the service life can be improved. With the increase of use time, magnesium alloy will still be corroded. Magnesium alloy has lower impact resistance and toughness compared to other metal materials such as aluminum alloy, and is prone to cracking, deformation or damage when subjected to impact or excessive pressure. The magnesium alloy radiator needs to be in a high temperature environment for a long time, especially under high temperature and rapid temperature change conditions, which may cause thermal fatigue. Thermal expansion and contraction can change the microstructure of the metal material, causing cracks or deformation. In the above problems, it is a big problem to repair the integrally formed magnesium alloy radiator, which is generally replaced as a whole, with high cost. At the same time, the heat dissipation effect of the radiator is related to the heat dissipation area, and the heat dissipation area of each group of heat dissipation fins in the magnesium alloy radiator is limited, and only the outer side. The heat dissipation area of the heat dissipation fin can be further improved. SUMMARY
