Abstract

本实用新型公开一种全钛复合耐蚀热交换器，有钛复合管(1)及与钛复合管(1)端口外接的钛复合板(2)，其特征在于：所述钛复合管(1)端口截面上有钛保护层(3)，钛保护层(3)的外边焊接在钛复合板(2)的钛层上。即方便与钛复合板焊接，使连接可靠、密封严密，避免粘接所存在的易老化、脱落的问题，提高了产品的可靠性；同时还可保证与介质相接触的面均为钛层，防止钛复合管的钢截面直接与介质相接触所存在的腐蚀现象，使整个产品的耐腐蚀效果好。

Description

全钛复合耐蚀热交换器
技术领域：
本实用新型涉及一种热交换器，尤其是一种可靠性高、耐腐蚀效果好的全钛复合耐蚀热交换器。
背景技术：
热交换器中有许多管与板的连接部位，即板与管的端口外侧相接且板与管的端头位于一个平面。目前，部分热交换器为了达到防腐且低成本的目的，选用内衬钛层的钛钢复合管及钛钢复合板。但是，由于现有钛钢复合管的端口是钛钢复合管的横截面，因此当钛钢复合管与钛钢复合板相接时，钛钢复合管的钢层需要与钛钢复合板表面的钛层相接，但二者之间只能采用胶粘接的方式，常发生因胶老化而脱落的现象，可靠性低；另外，裸露的钛钢复合管横截面中钢面与钛之间存在着电位差，尽管裸露的钢面积较小，但还是存在着易腐蚀的问题，并不能完全满足防腐的要求。
发明内容：
本实用新型为了解决现有技术所存在的上述技术问题，提供一种可靠性高、耐腐蚀效果好的全钛复合耐蚀热交换器。
本实用新型的技术解决方案是：一种全钛复合耐蚀热交换器，有钛复合管1及与钛复合管1端口外接的钛复合板2，所述钛复合管1端口截面上有钛保护层3，钛保护层3的外边焊接在钛复合板2的钛层上。
所述钛保护层3是钛复合管1的钛层翻边。
本实用新型是在钛复合管的端口处增加了钛保护层，即方便与钛复合板焊接，使连接可靠、密封严密，避免粘接所存在的易老化、脱落的问题，提高了产品的可靠性；同时还可保证与介质相接触的面均为钛层，防止钛复合管的钢截面直接与介质相接触所存在的腐蚀现象，使整个产品的耐腐蚀效果好。
附图说明：
图1是本实用新型实施例的结构示意图。
具体实施方式：
下面将结合附图说明本实用新型的具体实施方式。如图1所示：有钛复合管1及与钛复合管1端口外接的钛复合板2，钛复合管1和钛复合板2可以是钛钢(碳钢或合金钢)复合，在钛复合管1端口截面上有一圈钛保护层3，钛保护层3的外边焊接在钛复合板2的钛层上。为加工方便，钛保护层3最好是钛复合管1内衬钛层的翻边。
