Study enhances thermal management via tapered gap cold plates in electronics, suggesting improved cooling efficiency.
• A two-phase cold plate with a tapered gap was fabricated to enhance CHF under low-flow conditions. • Minimum thermal resistance of 0.061 K/W and >187.5 W/cm 2 heat flux achieved at H/W = 1 and θ = 20°. • CHF increased with inclination angle due to accelerated bubble growth and directed departure. • Low pressure drop (∼1 kPa) demonstrates strong potential for energy-efficient data center cooling.
