Abstract

用于换热装置的鱼鳞状内壁热传导管，使管中流体产生无规则的紊乱状态，其特征在于有色金属管内表面为鱼鳞状(菱形)凸起的表面。凸块的高度为0.1—3mm，菱形的斜角α为15—40度，其节距t为0.5—8mm。

Description

本实用新型属于换热装置的热传导管。
目前，现有技术中大都使用光滑内壁的有色金属管，其换热效率较低。在中国专利文献CN85103367和CN85107311中，揭示了内表面开有螺纹的热传导管，使热交换效率有所提高，然而管中流体的流动状态是呈螺旋状规则流动，虽增加了距离，但流体滞留管壁的时间并未延长，故不能进行充分的热交换。
本实用新型的任务是提出一种能破坏流体规则流动的表面形状。
本实用新型的热传导管，其特征在于在有色金属管内表面呈鱼鳞状（菱形）凸起的表面。
本实用新型的解决方案，由附图进行说明。
图为热传导管剖开后的展开图。
本实用新型的优点在于破坏了管中流体的层流状态，也破坏了呈螺旋状规则流动状态，而成为无规则的紊流状态，使内、外层次的流体产生撞击和搅拌，并增加了管壁的摩擦阻力，延长了流体滞留在管壁的时间，流体的热交换较充分，从而提高了换热效率，在同等效率情况下，可减少有色金属热传导管的长度。
本实用新型的最佳实施方案是，鱼鳞状（菱形）凸块的高度为0.1－3mm，菱形的斜角α为15－40度，其节距t为0.5－8mm。
