海水开架式气化器用高效星形换热管
摘要：
本实用新型公开了一种气化器用的高效星形换热管，包括外部星形翅片、内管以及扰流杆，是海水开架式气化器上的核心部件，属于液化天然气气化行业技术领域。其特别之处在于换热管具有双层结构，在换热管内部设置有内管和扰流杆，能有效降低换热管内外侧结冰的可能性，同时强化管内流体的湍流程度，有效提高换热效率。本实用新型结构简单、合理；制作成本低、外形美观和安全可靠，能提高气化器的性能。
摘要（英）：

The utility model discloses an efficient star-shaped heat exchange tube for a seawater open-frame type gasifier, which comprises an external star-shaped fin, an inner tube and a turbulence stem used as key parts on the seawater open-frame type gasifier. The utility model belongs to the technical field of the liquefied natural gas gasification industry. The efficient star-shaped heat exchange tube is characterized in that the heat exchange tube adopts a double-layer structure; and the inner tube and the turbulence stem are arranged inside the heat exchange tube so as to effectively reduce the icing possibility on the inner side and the outer side of the heat exchange tube and simultaneously strengthen the turbulence extent of fluid in the tube, and the heat exchange efficiency is effectively improved. The efficient star-shaped heat exchange tube has the advantages of simple and reasonable structure, low manufacturing cost and attractive appearance, is safe and reliable and can improve the performance of the gasifier.
