AI Technical Summary

Technical Problem

In existing fluidized bed radiators, the traditional fin structure enhances heat transfer but also results in significant flow resistance and pressure drop, affecting system stability and energy efficiency. It is difficult to balance enhanced heat transfer with flow stability.

Method used

Adopting a biomimetic design, drawing inspiration from the structural features of crescent-shaped sand dunes in nature, crescent-shaped sand dune fins are designed. The fins are arranged perpendicular to the flow direction, and the fins are staggered front and back to increase the heat exchange area, optimize the flow path, and reduce flow resistance.

Benefits of technology

It increases the heat transfer rate by 25%, reduces flow energy loss by 30%, achieves efficient and stable heat dissipation, and meets the thermal management requirements of high power density devices.
