Description

一种热管与水箱内胆的密封结构
技术领域
本实用新型涉及到一种超导热管与水箱的密封结构，属于太阳能热利用领域。
背景技术
目前的采用相变热管的太阳能热水器(以下简称热水器)，它作为太阳热水系统热的导热元件，是热水系统的重要组成部分。热管与水箱内胆的连接密封是保证热水器稳定的关键所在。在中国专利CN2685773Y中写明了一种相变热导管的密封接头形式。这种结构主要用于承压热水系统中，相对来说，结构复杂、工艺复杂、大量使用金属密封件成本高，如果要用于非承压系统就比较浪费。
实用新型内容
本实用新型的目的是设计一种热管与水箱内胆的密封结构，适用于非承压热水系统，它的安装简便，密封可靠，制造成本较低。
本实用新型包括热管和水箱内胆密封胶圈，其特征在于热管外壁上有一个密封铜箍，密封铜箍的外径大于热管外径，二者连接处无缝隙，密封铜箍的外径与胶圈内径相配合并形成密封。
通过图1来说明本实用新型。图中1是真空太阳集热管，2是水箱外壳，3是水箱保温层，4水箱内胆，5是胶圈，6是密封铜箍，7是热管，。在本方案中将密封铜箍的缩口端与热管焊接相连，并且完全焊死，使二者之间没有空隙。先将胶圈固定在水箱内胆的冲孔处，再将焊有密封铜箍的热管插入，密封铜箍的外径略大于胶圈的内径，这样，在密封铜箍装入胶圈后，就会依靠胶圈的弹性达到密封的效果。
本实用新型的优点是：由于直接采用了橡胶件作为连接热管与水箱的密封材料，减少了大量的金属密封接头，可以大大降低热水器的制造成本，且安装简便，使用可靠。
附图说明
图1是本实用新型的结构示意图；
图2是本实用新型具体实施方式1的结构示意图。
具体实施方式
图2给出了本实用新型的具体实施方式，图中1是真空太阳集热管，2是水箱外壳，3是水箱保温层，4水箱内胆，5是胶圈，8是带支撑片的密封铜箍，7是热管。在本方案中密封铜箍带有支撑片，用于支撑在胶圈的底部，这种结构更便于装配，在装配时不会因为用力过猛将密封铜箍直接穿过胶圈，也保证在使用中密封铜箍和热管不会再向里进，更便于定位。
这种结构非常简单又有效，安装方便，使用可靠。
