Problems solved by technology
[0005] In the current magnesium alloy series, the heat dissipation performance changes with the alloy content and phase composition. The commonly used extruded magnesium alloy is AZ31 (its thermal conductivity is 96m-K), but it is different from the commonly used aluminum alloy radiator 6063 (the thermal conductivity is 96m-K). 209W / m-K), the thermal conductivity is half the difference, so the thermal conductivity drops by more than 50%

Abstract
The invention provides a magnesium alloy radiator and a manufacturing method thereof. The magnesium alloy radiator comprises a plurality of radiating fins and a central ring column, wherein one end of each of the plurality of radiating fins is fixedly connected to the central ring column, and the plurality of radiating fins surround the central ring column to form a spoke shape or a spiral radial distribution, and the central ring column is provided with a heat conductive base plate for connecting an LED component to the magnesium alloy radiator. The magnesium alloy radiator according to the invention has the advantages of light weight, good heat dissipation, low cost and the like.
Description
technical field [0001] The invention relates to a radiator, in particular to a radiator made of magnesium alloy for LED lamps and a manufacturing method thereof. Background technique [0002] Compared with conventional lamps, LED lamps have the characteristics of energy saving, environmental protection, long life, small size, etc., and can better meet the needs of energy and the environment. Therefore, LED lamps have broad application prospects. Although LED lamps are energy-efficient, only 15% to 25% of the electrical energy they consume is converted into light energy, and the rest is converted into heat dissipation. Therefore, the heat dissipation performance directly affects the service life and luminous performance of LED lamps, especially high-power LED lamps, which generate more heat and require higher heat dissipation technology. The problem of heat dissipation is directly related to the development prospects of LED lamps. [0003] At present, the heat sink material...
