Description
超导真空双层热管
技术领域
本实用新型涉及一种太阳能集热管，特别是涉及一种超导真空双层热管。 背景技术
目前，太阳能技术已得以广泛应用，市场上现有多种太阳能集热管，但是， 现有的太阳能集热管，只在其内外壁间设置有真空层，即现有的集热管都是单 真空层结构，人们在实际应用中发现，具有上述结构的现有的太阳能集热管存 在保温效果较差、散热过快的缺陷，并且，由于现有的太阳能集热管内热管吸 热面积有限，而热管是太阳能集热管中最主要的集热部件，因此，现有太阳能 集热管的吸热效果较差。
发明内容
本实用新型的目的，是提供了一种超导真空双层热管，它可解决现有太阳 能集热管存在的问题，具有吸热效果好，散热率低的优点。
本实用新型是通过以下技术方案实现的：超导真空双层热管包括真空管， 真空管由外管和内管连接构成，外管与内管制成一体，外管与内管之间设有外 真空层，内管内安装胶塞，胶塞与内管构成内真空层，内真空层内安装超导热 管，超导热管的一端伸出胶塞外，内真空层内安装吸热翅片，吸热翅片与超导 热管连接，吸热翅片位于超导热管外周，吸热翅片的横断面是圆弧形，吸热翅 片的外表面设置吸收膜，吸收膜与内管的内壁紧密接触。
为进一步实现本实用新型的目的，还可以采用以下技术方案实现：胶塞的 横断面形状与内管的横断面形状相同，胶塞的侧壁与内管的内壁紧密接触。胶
塞是硅胶密封塞。吸热翅片的横断面对应的圆心角a的范围是180至300度。外真空层内的真空度是5. 0Xl(TPa。本实用新型的积极效果在于：它具有双层真空结构，可有效地提高保温效 果，防止热管所吸收的热量散失；它的热管与吸热翅片连接，吸热翅片扩展了 热管的吸热面积，从而可提高热管的吸热效率，最终增加了真空管整体的吸热 效果。 附图说明图1是本实用新型的结构示意图；图2是图1的A-A剖视放大结构示意图； 图3是图1的俯视放大结构示意图。图中标号：1-外管、2-内管、3-外真空层、4-吸收膜、5-吸热翅片、6-内 真空层、7-超导热管、8-胶塞。具体实施方式本实用新型所述的超导真空双层热管包括真空管，真空管由外管1和内管2 连接构成，外管1与内管2制成一体，外管1与内管2之间设有外真空层3，内 管2内安装胶塞8，胶塞8位于内管2的上部，胶塞8与内管2构成内真空层6， 内真空层6内安装超导热管7，超导热管7的一端伸出胶塞8外，内真空层6内 安装吸热翅片5，吸热翅片5与超导热管7连接，并且吸热翅片5位于超导热管 7外周，吸热翅片5的横断面是圆弧形，吸热翅片5的外表面设置吸收膜4，吸 收膜4与内管2的内壁紧密接触，吸热翅片5外表面设置吸收膜4这种结构比 传统的真空集热管在内管的外表面设置吸热涂层吸热效果较好，而且吸收膜4 与吸热翅片5连接，吸收膜4吸收的热量可通过吸热翅片5快速高效地传递给 超导热管7，热损失较少。由于吸收膜4与内管2的内壁紧密接触，内管2与吸 收膜4间的热阻较小，内管2吸收的热量会由吸收膜4和吸热翅片5快速传递给超导热管7,从而，可最大限度的将真空热管上所有部件吸收的全部热量传递 给超导热管7。本实用新型所述的超导真空双层热管具有内真空层6和外真空层 3双层真空结构，外真空层3的真空度是5. 0X10—3Pa，双层真空层可有效地的提 高吸收比，减少热量散失，提高集热效果。表面设置吸收膜4的吸热翅片5可 有效增加热效。内真空层6可防止吸热翅片5表面设置的吸收膜4被氧化，从 而可延长真空热管的使用寿命。
为了提高内管2与胶塞8间的密封效果，确保内真空层6内的真空度，可 使胶塞8的横断面形状与内管2的横断面形状相同，并且，在未装配时，胶塞8 的直径应大于内管2的内径，当胶塞8与内管2装配后，胶塞8与内管2应为 过盈配合，装配后胶塞8的侧壁与内管2的内壁紧密连接。
为使胶塞8和内管2间连接更加紧密，确保内真空层6的真空度恒定，胶 塞8可以是硅胶密封塞，硅胶密封塞既可与由玻璃制成的内管2紧密接触，又 具有抗腐蚀，使用寿命长的优点。
为了增加吸热效果可增加吸热翅片5的面积，由于吸热翅片5紧贴内管2 的弧形内壁，因此，吸热翅片5的横断面积与内管2的内壁形状相同，吸热翅 片5的横断面所对应的圆心角是a ，为确保真空管具有较好的吸热效果，d的 范围可以是180至300度，经实验得出，当吸热翅片5的橫断面的圆心角a为 270度时，单位面积的平均吸热效率达到最大值。为提高导热效果，减少热损失， 吸热翅片5可以是铜片。
本实用新型由于采用超导热管7传递热量，放热端管径小，因此可以实现 集热管的无间隙排列，从而可增加单位面积内的集热面积。
本实用新型的技术方案并不限制于本实用新型所述的实施例的范围内。本 实用新型未详尽描述的技术内容均为公知技术。
