The latest research and development design of Raspberry Pi 5 motherboard aluminum heat dissipation

Material advantages

Lightweight and High Strength: The low density of aluminum makes the entire heat dissipation shell lightweight, easy to carry and install. At the same time, aluminum alloy has high strength, which can effectively protect the Raspberry Pi 5 motherboard and prevent damage during handling, installation, and use.

Strong corrosion resistance: The aluminum shell has excellent corrosion resistance, and a strong and corrosion-resistant oxide film is easily formed on its surface. It can be used for a long time under harsh environmental conditions without being easily damaged by oxidation, corrosion, etc., which helps to maintain the stable heat dissipation performance of the shell and extend the service life of the equipment.

Heat dissipation performance：

High thermal conductivity: The thermal conductivity of aluminum is about 205W/(m · K), which is a relatively high level among metal materials. This enables the aluminum heat dissipation shell to quickly transfer the heat generated by the Raspberry Pi 5 motherboard to the surface of the shell, and dissipate it to the environment through air convection or radiation, effectively reducing device temperature.

Ventilation design: Multiple ventilation holes are usually designed, such as at the top, bottom, or side of the casing, which can accelerate air flow, form good convection, and dissipate heat faster. When used in conjunction with a cooling fan, the cooling effect is better.
Temperature uniformity: Good thermal conductivity helps to evenly distribute heat throughout the entire shell, avoiding local overheating of the Raspberry Pi 5 motherboard and extending the service life of the motherboard and other components.
