| 目的 研究海上电子设备翅片散热器所涂覆防腐涂料的导热系数对散热器散热性能的影响规律，提高翅片散热器的散热效能。方法 以六方氮化硼粉体为导热填料，将其添加的海上电子装备防腐涂料中，制备添加不同量六方氮化硼的改性防腐涂料，分别研究六方氮化硼对涂层热导率、附着力、冲击性、柔韧性以及耐中性盐雾性能的影响规律，优化配方设计。最后基于上述试验结果，以铝合金翅片散热器为模型，研究不同模拟热源情况下，散热器涂覆六方氮化硼改性防腐涂层前后的散热性能。结果 翅片散热器防腐涂层的热导率随掺入六方氮化硼质量分数的增加而提升，在20%时达到最大值(λ≈1.03 W.m–1.K–1)，力学性能在添加量为15%时达到最优。相比未改性的防腐涂料，涂覆六方氮化硼改性防腐涂料的铝合金散热器，在自然对流条件下以及加热功率20 W时，可使其平衡温度下降约5 ℃。结论 通过在防腐涂料中添加六方氮化硼，在涂层中构筑了导热网络，降低了涂层传导热阻，提高了经过涂层表面的热流密度，显著提升了铝合金散热器的热管理效能。上述高导热防腐涂层在海洋环境下服役设备的热管理应用方面具有良好的应用前景。 |

| The work aims to investigate the effects of thermal conductivity of anti-corrosion coating on the heat dissipation performance of ship borne electronic equipment fin radiators, and improve the heat dissipation efficiency of fin radiators. With hexagonal boron nitride powder as a thermal conductive filler, modified anti-corrosion coatings with different amounts of hexagonal boron nitride were prepared for ship electronic equipment anti-corrosion coatings. The effects of hexagonal boron nitride on the thermal conductivity, adhesion, impact resistance, flexibility, and neutral salt spray resistance of the coatings were studied, and the formulation design was optimized; Finally, based on the above experimental results, the heat dissipation performance of aluminum alloy finned radiators before and after coating with hexagonal boron nitride modified anti-corrosion coatings was studied under different simulated heat source conditions. The thermal conductivity of the anti-corrosion coating on the finned radiator increased with the increase of the mass percentage of hexagonal boron nitride added, reaching its maximum value (λ≈1.03 W.m–1.K–1) at 20wt%, and the mechanical properties reached their optimal value at a dosage of 15wt%; Compared with unmodified anti-corrosion coatings, aluminum alloy radiators coated with hexagonal boron nitride modified anti-corrosion coatings could lower their equilibrium temperature by~5 ℃ under natural convection conditions and heating power of 20 W. By adding hexagonal boron nitride to anti-corrosion coatings, a thermal conductivity network is constructed in the coating, reducing the thermal resistance of the coating and increasing the heat flux density passing through the coating surface, significantly improving the thermal management efficiency of aluminum alloy heat sinks. The above-mentioned high thermal conductivity anti-corrosion coating has good application prospects in the thermal management of shipborne equipment serving in marine environments. |
