Description

双管板换热器中管板与换热管的联接结构 技术领域
本发明涉及双管板换热器， 具体地说是一种双管板换热器中管板与换热管 的联接结构。
背景技术
双管板换热器应用在化工、 医药、 制药、 化学试剂、 生化及电子、 多晶硅 等行业中， 用于产品在热量交换过程中由于换热器泄漏造成两程之间的物料相 混合将产生严重后果的情况下使用。 如在制药行业中注射用水配水系统， 国家 明确要求采用双管板注射用水冷却器， 以防止因冷却水泄漏引起污染药品， 但 制药企业几乎没有按照要求做， 主要原因是市场上没有结构紧凑的、 产品质量 稳定的双管板注射用水冷却器产品， 仅全国几千家药厂至少要求使用几万台， 也可以说是有几万个用水点没有达标， 严重影响到 GMP (Good Manufacturing Practice, 药品生产质量管理规范） 的实施。
目前， 市场上双管板换热器的内管板与换热管的联接大多采用金属胀接， 即换热管放置在管孔中， 用张管器将换热管扩张， 促使换热管与内管板贴紧， 以达到密封之目的。 但这种联接结构要求管板与换热管具有足够的强度， 即管 板与换热管均要有足够的厚度， 以保证它们相互间的可靠结合， 因此无法用于 薄管板、 薄管子制成的换热器； 而釆用厚管板及厚管子的换热器， 其单位截面 面积中的换热面积会随之减少， 设备制造成本增加， 体积增大。 另外， 采用金 属胀接联接的换热器， 在使用中也会因温差产生热胀冷缩、 受外力产生移位或 长期的工作疲劳等情况造成贴紧力下降而降低密封效果， 产生泄漏。
发明内容
本发明针对上述问题， 提供一种双管板换热器中管板与换热管的联接结构， 该联接结构密封可靠， 可用于薄管板与薄管子制成的换热器， 增加单位截面面 积中的换热面积。
按照本发明的技术方案： 一种双管板换热器中管板与换热管的联接结构， 包括外管板、 内管板及换热管， 所述外管板及所述内管板上开有相对应的安装 所述换热管的管孔， 所述换热管与所述外管板之间焊接联接， 所述内管板固定 在壳体上， 所述内管板的一侧固定有开有相对应管孔的盖板， 所述盖板与所述 内管板之间设置有与所述管孔同轴的密封槽， 所述密封槽中安装有与所述换热 管过盈配合的密封圈。
所述盖板位于所述内管板的外侧。
所述盖板位于所述内管板的内侧。
所述密封槽位于所述内管板上。
所述密封圈为非金属弹性体。
所述密封圈为 O型密封圈。
所述盖板与所述内管板之间设置有定位装置。
本发明的技术效果在于： 本发明在内管板的一侧固定有盖板， 内管板与换 热管采用密封圈联接， 形成柔性弹性联接， 可实现薄管板、 薄管子制成的双管 板换热器， 结构紧凑， 使双管板换热器的制造成本大幅下降且能提高换热效果， 增加单位截面面积中的换热面积， 实现设备小型化， 扩大其使用场合； 本发明 的联接结构密封可靠， 不会受冷热温差、 外力及长期的工作疲劳而降低密封效 果， 不会泄漏。
附图说明

图 1、 图 2中， 包括外管板 1、 内管板 2、 密封槽 3、 密封圈 4、 盖板 5、 壳 体 6、 换热管 7、 管孔 8等。
如图 1、图 2所示，本发明是一种双管板换热器中管板与换热管的联接结构， 包括外管板 1、 内管板 2及换热管 7。 外管板 1及内管板 2上开有相对应的安装 换热管 7的管孔 8， 换热管 7与外管板 1之间焊接联接， 内管板 2通过焊接固定 在壳体 6上。
本发明在内管板 2的一侧固定有开有相对应管孔 8的盖板 5，盖板 5与内管 板 2之间设置有与管孔 8同轴的密封槽 3 ,密封槽 3中安装有与换热管 1过盈配 合的密封圈 4。密封圈 4为非金属弹性体，选用与物料介质接触不会发生化学变 化的材料， 在长期的使用过程中仍保持稳定， 其密封处于良好状态。 密封圈 4 最好采用 Q型密封圈
如图 1所示， 是本发明的第一种实施例。该实施例中， 盖板 5位于内管板 2 的内侧， 即处于壳体 6内， 密封槽 3位于内管板 2上。
如图 2所示， 是本发明的第二种实施例。该实施例中， 盖板 5位于内管板 2 的外侧， 即处于壳体 6外， 密封槽 3也位于内管板 2上。
