内容記述 |
Enhancing pool boiling performance is vital for developing next-generation two-phase immersion cooling techniques for high-power-density electronics. However, conventional surface manufacturing methods cannot meet the diverse demands of the “nucleation-growth-coalesce-departure” life cycle of bubbles that usually require complex topologies and also across scales. To address these challenges, we design and fabricate 3D metallic porous lattice structures through laser powder bed fusion (L-PBF) technique with large fabrication freedom and accuracy. The design enables efficient bubble departure and continuous liquid replenishment through well-separated liquid-vapor pathways. Our large area experiments (706.9 mm^2) exhibit an optimal critical heat flux (CHF) of 1758.3 kW/m^2 and heat transfer coefficient (HTC) of 87.0 kW/(m^2 K), indicating top-level capacity for large area heat dissipation, close to real-case demands. We demonstrate that balancing lattice geometry, pore size, and surface bonding is essential and propose a general instruction for optimizing the overall performance. In comparison to reported small-area designs (usually < 300 mm^2) whose performances deteriorate as the area increases, the proposed strategy provides reliable principles for innovative structure design in practical thermal management of large-area power electronics and computing devices. |
