🖨️ We tested 3D printed lattice heatsinks against conventional fins using CFD. The results weren't even close. Published in Applied Thermal Engineering (2023), this study directly answers one of the most pressing questions in modern electronics cooling: has additive manufacturing finally made conventional fin heatsinks obsolete? The Problem Every high-performance system — GPUs, power electronics, EV inverters, aerospace avionics — generates heat that must be removed fast and efficiently. Conventional integral fin heatsinks have been the industry standard for decades. They work. But they're a product of what was manufacturable, not what's optimal. 3D printing changes that equation entirely. What Was Tested Two 3D printed heatsink geometries built from periodic lattice structures — Simple Cubic (SC) and Body-Centered Cubic (BCC) — evaluated against a conventional integral fin design using validated 3D CFD (RANS with SST turbulence model). Two coolants: water and supercritical CO2. What the Data Showed → SC lattice: 4.45x higher overall performance (PEC) than conventional fins at 1.5 L/min → BCC lattice: 4.33x higher PEC at the same conditions → Pressure drop: up to 40x lower in printed heatsinks → Vortex generation within BCC topology actively enhances heat transfer coefficient The lattice geometry forces fluid into complex mixing patterns that flat fins simply cannot replicate. Why This Matters A 4.45x performance gain means smaller, lighter cooling systems for the same thermal load. A 40x pressure drop reduction means less pumping power, lower energy consumption, and longer system life. For data centres, EV powertrains, and aerospace electronics — these numbers aren't incremental. They're generational. This is the intersection AENS Consulting operates in — thermal systems CFD, electronics cooling simulation, and heat exchanger design. We model the physics that drives better engineering decisions.
