To ensure that the multi-screen shell processed by CNC hardware has good heat dissipation performance, you can start from the following aspects:1. Material selectionAluminum alloy: Aluminum alloy is one of the commonly used materials in CNC hardware processing. It has good thermal conductivity and light weight, and is an ideal choice for manufacturing shells with good heat dissipation performance.Copper alloy: The thermal conductivity of copper alloy is better than that of aluminum alloy, but the cost is relatively high. You can choose according to product requirements and budget.Consider the thermal expansion coefficient of the material: Select a material whose thermal expansion coefficient matches the internal electronic components to reduce thermal stress caused by temperature changes, thereby maintaining the integrity and heat dissipation performance of the shell.2. Structural designIncrease heat dissipation channels: Add heat dissipation channels such as heat dissipation holes and heat sinks to the shell design to improve heat dissipation efficiency. The design of the heat dissipation channel should take into account the direction and speed of air flow to ensure that heat can be quickly dissipated.Optimize the internal structure: By optimizing the internal structure layout, reduce the thermal resistance between internal components and improve the heat transfer efficiency. For example, the position of electronic components can be reasonably arranged to make it easier to dissipate heat.Use heat sink fins: Add heat sink fins on the surface or inside of the shell to increase the heat dissipation area and improve the heat dissipation effect. The design of the heat sink fins should take into account its shape, size and distribution to ensure the best heat dissipation performance.3. Surface treatmentAnodizing: Through anodizing, a solid oxide film can be formed on the surface of the shell to improve the corrosion resistance and wear resistance of the shell. At the same time, the anodized film can also increase the heat dissipation area on the surface of the shell and improve the heat dissipation performance.Sandblasting: Sandblasting can increase the roughness of the shell surface and improve the heat dissipation efficiency. However, it should be noted that sandblasting should be moderate to avoid excessive wear of the shell surface or affect the aesthetics.Spraying heat dissipation paint: Spraying heat dissipation paint on the shell surface can improve the heat dissipation performance of the shell. Heat dissipation paint usually has high thermal conductivity and good radiation heat dissipation ability, which can effectively dissipate heat from the shell surface.4. Manufacturing processEnsure processing accuracy: During the CNC hardware processing, the processing accuracy and surface quality should be ensured to reduce the thermal resistance caused by processing errors. The higher the processing accuracy, the better the heat dissipation performance of the shell.Reasonable control of processing temperature: During the processing, the processing temperature should be reasonably controlled to avoid excessive temperature causing thermal deformation of the material or excessive thermal stress. At the same time, the cooling effect during the processing should also be ensured to reduce heat accumulation.5. Testing and verificationHeat dissipation performance test: After the shell is manufactured, a heat dissipation performance test should be carried out to verify whether its heat dissipation performance meets the design requirements. The test method can be detected by thermal imagers, temperature sensors and other equipment.Long-term stability test: During actual use, the shell may be affected by various factors, such as temperature changes, humidity changes, etc. Therefore, a long-term stability test should be carried out to evaluate the stability of the heat dissipation performance of the shell during long-term use.Through reasonable material selection, structural design, surface treatment, manufacturing process, testing and verification and other measures, it can be ensured that the multi-screen shell processed by CNC hardware has good heat dissipation performance.
