Product Description
Extruded Mg Magnesium Alloy AZ91D Heat Sink China Manufacturer
Description
Magnesium alloys have advantages in heat dissipation relative to 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 easier to transfer from the root of the heat sink to the top of the magnesium alloy than the aluminum alloy. Speed, the top is easier to reach high temperature. 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 material, so it accelerates the diffusion and convection of the air inside the radiator and improves the heat dissipation efficiency. Therefore, at the same temperature, the heat dissipation time of magnesium alloy is not half that of aluminum alloy.
As the lightest structural material, magnesium alloy has low specific gravity (about 23% of steel and 64% of aluminum) and high specific strength and stiffness.Good thermal and electrical conductivity;With good electromagnetic shielding, damping, shock absorption, and cutting and die casting process performance.

Heat sinks are thermally conductive components or devices that absorb and dissipate heat generated by electronic components. Heat sinks cool high-powered devices to prevent overheating. The reliability of electronic components is generally reduced by the square of an increase in temperature. For example, doubling the ambient temperature around a component renders the component 25% less reliable than at the lower temperature. Heat sinks are therefore essential in dissipating generated heat and improving component longevity.
