Abstract
To address the limited passive operation time of the accident cooling water tank in the secondary passive residual heat removal system of the HPR1000 nuclear power plant caused by boiling dryout,this study proposes a high-performance heat pipe unit fabricated by additive manufacturing.Heat transfer limit analysis reveals that the conventional heat pipe is pri-marily constrained by the entrainment limit,boiling limit,and heat transfer limits at the evaporator and condenser sections.Accordingly,a selective laser melting(SLM)additive manufacturing process is employed to fabricate a complex structure featuring internal lattice structures and external thin fins for both evaporator and condenser sections.A diversion sleeve is added to the condenser section to enhance natural convection heat transfer.Numerical results show that the chimney effect induced by the diversion sleeve more than doubles the heat transfer capacity compared to the configuration without a sleeve.A gravity heat pipe test bench is established to evaluate the thermal performance under various structural combinations and liquid filling amounts.Experimental results demonstrate that the additively manufactured heat pipe achieves significantly im-proved heat transfer performance,with the HP-1-4 configuration(combining a complex evaporator and multiple modular condensers)reaching a maximum heat transfer capacity of 2 187 W.This study confirms the effectiveness of additive manu-facturing in enhancing the heat transfer area and efficiency of heat pipes,offering a promising solution for extending the pas-sive operation duration of residual heat removal systems.关键词
