Magnesium Heat Sink for Die Casting Extrusion Magnesium Alloy Heat Sink Radiator Material
Magnesium Heat Sink have absolute advantages over aluminum alloys. For heat sinks of magnesium alloy and aluminum alloy materials of the same volume and shape, the heat (temperature) produced by a certain heat source is more likely to be transferred from the root of the heat sink to magnesium alloys than aluminum alloys. 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.
