摘要：

船舶在极区航行时, 甲板设备和管道的结冰会对船体的结构强度、稳定性和动力系统等造成影响, 而电伴热防冰技术是解决该问题的有效手段之一。本文开展的极区船舶扶手管涂覆层及其对电伴热影响实验的结果表明: (1)涂层可提升扶手管表面升温速率, 同时降低扶手管传热系数; (2)在–40~–10 ℃环境范围内, 扶手管表面升温差异不显著, 同一温度, 风速从5 m·s–1上升至7 m·s–1时, 其表面升温幅度下降约24%, 此外, 有涂层扶手管的表面升温较无涂层圆管普遍提高30%左右; (3)涂层会改变扶手管表面的对流换热系数, 在相近的环境条件下, 有涂层的扶手管表面温度较无涂层管提升1~2 ℃, 这一升温效应直接增强了其防冰效果。

Abstract:

The icing of equipment and pipelines on ships affects the structural strength, stability, and power systems of the vessels when navigating in the polar regions. Anti-icing technology based on electric heating is effective for addressing the icing of equipment and facilities on the upper decks. This study analyzes the relationship between the coating layer and the convective heat transfer coefficient of the round pipe and the thermal balance performance of the electric trace heating handrail pipe. The research findings indicate that: (1) the temperature increase of the surface of a coated pipe is higher than that in an uncoated pipe and heat stored in the wall is also higher. The coating layer can increase the thermal resistance for heat radiation from the pipe and reduce the convective heat transfer coefficient of the round pipe. (2) Within the environmental range of –40 to –10 ℃, the difference in surface temperature rise of handrail pipes is not significant. At the same temperature, when the wind speed increases from 5 m·s–1 to 7 m·s–1, the magnitude of its surface temperature rise decreases by approximately 24%. Additionally, the surface temperature rise of coated handrail pipes is generally about 30% higher than that of uncoated round pipes. (3) The coating layer has a certain insulation effect; it changes the convective heat transfer coefficient of the pipe surface. Under similar environmental conditions, the surface temperature of the coated handrail is 1~2 ℃ higher than that of the an uncoated, thereby improving the anti-icing effect.
