本实用新型属于太阳能热管技术领域，涉及一种用于太阳能集热器的高效翅片热管组件。
背景技术
当前国内外太阳能热水器集热器内均采用导热翅片传递热量，将真空玻璃管上吸收的热量传递到热管上，导热翅片均由紫铜薄板或铝薄板制成，由于导热翅片的板材较薄，加工成型与热管组合装配进真空玻璃管后，由于翅片较薄，弹性差易变形，经过高温或振动后经常出现导热翅片与真空玻璃管接触不良，导致导热翅片的热传导效率不高，因导热翅片长期的导热不均，翅片容易变形。
实用新型内容
本实用新型所要解决的技术问题是，克服现有技术的缺点，提供一种用于太阳能集热器的高效翅片热管组件，提高导热翅片的支撑性，确保导热翅片与吸热管状物的接触贴合，改善太阳能集热器的热传导效率。
为了解决以上技术问题，本实用新型提供一种用于太阳能集热器的高效翅片热管组件，包括热管、翅片及数个卡接支撑件，所述翅片被加工成包含内圆和外圆的结构，所述翅片的内圆和外圆同轴，所述热管插入翅片的内圆中，且所述热管与翅片的内圆紧密配合；在所述翅片的内圆外壁面装配有卡接支撑件，所述卡接支撑件的横截面结构也具有与所述翅片横截面结构类似的同轴支撑内圆和支撑外圆结构，所述卡接支撑件的支撑内圆具有向内收缩的弹性力，所述支撑外圆具有向外扩张的弹性力；由所述卡接支撑件的支撑内圆将所述翅片的内圆紧密包覆在所述热管上；所述卡接支撑件的支撑外圆将所述翅片外圆紧密贴合在集热器管道的内壁上；可对热管和翅片之间的配合以及翅片和外部零件之间的配合起到紧固作用
本实用新型进一步限定的技术方案是：前述的用于太阳能集热器的高效翅片热管组件，卡接支撑件外圆上具有收缩边，用于更好的与翅片的贴合，便于导热翅片的安装，防止末端对管道内壁造成损伤。
进一步的，前述的用于太阳能集热器的高效翅片热管组件，所述卡接支撑件可由柱状或片状具有弹性材料制作而成，确保支撑件具有足够的弹性势能，能够完全将导热翅片撑开。
本实用新型的有益效果是：
本实用新型结构紧凑，制造安装方便，卡接支撑件可一次成型，通过卡接支撑件将翅片与热管和真空玻璃管紧密连接进行热传导，将太阳能集热器、平板集热器的热转化效率大大提高，提高导热翅片的稳定性，不会出现因局部温度过高而变形的问题，使用寿命长，故障率低。
