This study focuses on enhancing pool boiling heat transfer by developing copper-coated surfaces using copper nanoparticles. The primary objective is to analyse the performance of pool boiling on these coated surfaces compared to bare copper surfaces. The surfaces were coated using the thermal vapour deposition (TVD) method with single and double layers of copper nanoparticles. Surface characteristics such as coating thickness, contact angle, and porosity were evaluated using FEG-SEM and other techniques. Pool boiling experiments were conducted using DI water as the boiling liquid. The results showed a significant improvement in critical heat flux (CHF) and heat transfer coefficient (HTC) for the coated surfaces. The first layer of coating (14 μm) demonstrated the highest CHF, with an enhancement of 102.66% compared to the bare surface. The BHTC also increased by 147.41% for the first layer of coating. The study concludes that the TVD technique is an effective and cost-efficient method for enhancing pool boiling heat transfer, with potential applications in high-heat-flux cooling systems.

摘要

This study focuses on enhancing pool boiling heat transfer by developing copper-coated surfaces using copper nanoparticles. The primary objective is to analyse the performance of pool boiling on these coated surfaces compared to bare copper surfaces. The surfaces were coated using the thermal vapour deposition (TVD) method with single and double layers of copper nanoparticles. Surface characteristics such as coating thickness, contact angle, and porosity were evaluated using FEG-SEM and other techniques. Pool boiling experiments were conducted using DI water as the boiling liquid. The results showed a significant improvement in critical heat flux (CHF) and heat transfer coefficient (HTC) for the coated surfaces. The first layer of coating (14 μm) demonstrated the highest CHF, with an enhancement of 102.66% compared to the bare surface. The BHTC also increased by 147.41% for the first layer of coating. The study concludes that the TVD technique is an effective and cost-efficient method for enhancing pool boiling heat transfer, with potential applications in high-heat-flux cooling systems.
