Description

一种内插弹簧外加螺旋翅片的高温热管
技术领域
本发明属于传热学的工程应用技术领域。
背景技术
换热元件作为热量交换的设备,被广泛应用于能源、动力和化工等领域;现如今由于能源短缺问题严重,高效紧凑换热元件的研制对节能和降低成本具有重要意义。
高温热管是一种高效换热元件,其通过金属工质的气、液相变传热,具有极高的换热能力,目前是热管领域的热门研究方向之一;高温热管在高超声速飞行器热防护、空间核反应堆冷却、太阳能利用等方面具有广阔的应用前景。
现有的筒形高温热管存在以下不足之处:
1、金属工质在蒸发段易形成边界层,会阻碍对热源热量的吸收,传热系数不高,易发生冷态启动极限导致高温热管启动失败。
2、蒸气在冷凝段的冷凝一般是通过空气对流散热来完成,换热面积较小,冷凝效果较差。
发明内容
本发明的目的是为了解决现有的高温热管传热系数低、易发生冷态启动极限以及冷凝效果差的问题,提出了一种内插弹簧外加螺旋翅片的高温热管。
本发明所述的一种内插弹簧外加螺旋翅片的高温热管,该高温热管包括管壳;
所述管壳为两端封闭的筒形结构;
该高温热管还包括毛细芯、内插弹簧和翅片;
所述管壳的一端为蒸发段,管壳的另一端为冷凝段,在管壳的蒸发段与冷凝段之间为绝热段;其中,热源作用于管壳的蒸发段,管壳的冷凝段散热于冷源;
所述毛细芯设置在管壳的内侧壁上;
所述内插弹簧为螺旋状结构,并设置在管壳蒸发段的毛细芯内壁上;
所述翅片设置在管壳冷凝段的外壁上。
本发明的工作原理为:当热源作用于管壳的蒸发段时,毛细芯内部液体吸热形成流体,流体在内插弹簧的扰动作用下被加强,进而破坏热源与管壳的边界层发展,实现了强化换热;同时,流体经过管壳绝热段向管壳冷凝段运动,流体运动到管壳冷凝段时开始散热,形成冷凝液体,冷凝液体经由毛细芯回流到管壳蒸发段,构成完整循环;流体散出的热量经由翅片实现对流换热。
本发明的有益效果是内插弹簧具有加强管壳蒸发段流体扰动的作用,进而破坏热源与管壳边界层的发展,强化管壳蒸发段气、液相变换的热效果,提高了传热系数,从而缩小高温热管的几何尺寸,提高结构的紧凑性并减少成本;翅片能够大大增加管壳冷凝段的换热面积,可以强化管壳冷凝段的对流散热过程,并降低流动阻力,减少金属消耗量,不易发生冷态启动极限,冷凝效果较好,从而提高了高温热管的经济性和运行可靠性。
