The heat dissipation capacity of OEM chassis integration is not solely determined by the size of the equipment. The selection and adaptation of fin shapes directly determine the operating efficiency of the equipment in different working conditions. Different structures of fins have their own applicable scenarios and there is no universal type. Common OEM chassis integration fins include straight, wavy, serrated, and louvered types, and the structural differences bring significant distinctions in the fluid turbulence effect and wind resistance characteristics. The straight fin structure is regular, with low fluid resistance and low dust accumulation probability, and the airflow or liquid flow passes smoothly when passing through, suitable for conventional heat exchange working conditions with high cleanliness, stable flow rate, and low resistance requirements. However, its turbulence effect is weak, and the heat exchange efficiency is relatively stable. The wavy fin has a continuous bending structure that disrupts the laminar flow state of the fluid, increasing the contact time of the fluid with the fins, and has better heat exchange effect than the straight fin, suitable for most industrial hydraulic and conventional air-cooling scenarios. The serrated fin can continuously interrupt the boundary layer of the fluid, enhancing the heat exchange efficiency, but it will increase the fluid resistance, and is more suitable for compact working conditions with high temperature difference and high heat exchange requirements. The louvered fin has an opening-closing structure that can strengthen the air flow disturbance, suitable for precision equipment scenarios with lightweight and high heat dissipation requirements. Many selection misunderstandings are due to blindly choosing high heat exchange fins, ignoring the resistance matching issue, resulting in increased system energy consumption. Reasonable matching of fin shape, combined with the working condition flow rate, medium cleanliness, and temperature difference requirements for selection, can enable OEM chassis integration to achieve a balance between energy consumption and heat exchange efficiency, and adapt to various specialized industrial scenarios.
