Magnesium Heat Sink Die Casting Magnesium Radiator Heat Sink Extrusion
Magnesium Heat Sink Magnesium alloy has an absolute advantage in heat dissipation relative to alloys. For radiators of the same volume and shape of magnesium alloy and aluminum alloy, the heat (temperature) produced by a certain heat source is easier to transfer from the root of the heat sink than aluminum alloy. The speed to the top makes it easier for the top to reach high temperatures.
That is, the temperature difference between the root and top of the radiator made of aluminum alloy material is smaller than that of the radiator made of magnesium alloy material. This means that the temperature difference between the air temperature at the root of the heat sink made of magnesium alloy and the air temperature at the top is larger than that of the heat sink made of aluminum alloy.
Therefore, the diffusion and convection of the air inside the radiator are accelerated, and the heat dissipation efficiency is improved. Therefore, at the same temperature, the heat dissipation time of magnesium alloy is not half that of aluminum alloy.
