Abstract
A novel galvanic-polishing-assisted near net shape forming was proposed to improve the heat dissipation capacity of the liquid-cooled plates. The coarsest upper surface roughness of channels was reduced from 74 to 37 μm. The coolant flow rate and heat dissipation capacity of the liquid-cooled plates with the polished channels were increased by 35.2 and 51.0 pct compared with those of untreated liquid-cooled plates, respectively.
