❄🔬 Thermal Simulation Deep Dive: Which Flow Channel Delivers the Best Cooling for Liquid Cold Plates?
💧 Study Objective: Compare the cooling performance of three flow channel designs—Ordinary Flow Channel, Micro channel, and Manifold Channel—for liquid cold plates.
⚙️ Simulation Setup :
✅ Consistent dimensions across all three liquid cold plates
✅ Unified inlet/outlet positions (left = inlet, right = outlet)
✅ 12 chips mounted uniformly under the cold plate base
✅ Identical heat source power & flow rate (0.75L/min) for fair comparison
📊 Key Findings:
Focus: Hydraulic distribution inside the cold plate + chip junction temperature distribution
Winner for cooling efficiency: Micro channel design (delivers the best heat dissipation)
Trade-off: Micro channel also exhibits the highest pressure drop
