Description

应用于燃气热水器的热交换器
技术领域
本发明涉及一种热交换器(又称换热器)，尤其涉及一种应用于燃气热水器的换热装置。
背景技术
在燃气热水器领域，热交换器中的壳体1a和盘绕管2a多为分离的两部分，如图1和图2所示，盘绕管2a通过附着在壳体1a外壁进行热交换，从而使水温升高。这样的设计存在如下不足：首先，壳体和盘绕管存在间隙，热交换性能不高；其次，壳体表面温升较高，存在安全隐患；再次，壳体表面与空气直接接触，热损耗较高；最后，盘绕管附着在壳体外壁，占用空间。
发明内容
本发明所要解决的技术问题是针对上述的技术现状而提供一种热交换充分且热损耗低的应用于燃气热水器的热交换器。
本发明解决上述技术问题所采用的技术方案为：一种应用于燃气热水器的热交换器，包括壳体及设于壳体外壁的盘管，其特征在于所述壳体的外壁具有条形的第一凹槽，所述壳体的外壁设有紧贴设置有贴合板，该贴合板上成型有条形的第二凹槽，该第二凹槽与前述第一凹槽对接拼合形成水管通道。
进一步，所述的第一凹槽为至少两个并上下间隔布置，对应地，所述的第二凹槽也为至少两个并上下间隔布置。
所述的第一凹槽之间成型有条形的第三凹槽，对应地，所述的第二凹槽之间成型有条形的第四凹槽，该第四凹槽与前述的第三凹槽对接拼合形成空气夹层通道或真空通道。增加真空或空气层或填充隔热材料，减少与外部空气的热交换，进一步降低热损耗。
所述的贴合板与壳体的外壁可以通过焊接为一体，或通过连接构件连接为一体，或通过卡扣为一体。
进一步，所述的壳体内设有贯穿通过的内管，该内管与水管通道通过弯管连接。
与现有技术相比，本发明的优点在于：将壳体和水管通道合为一体，两者之间无缝隙连接，可减少与外部空气的热交换，减少热损耗，提高热交换率，减少占用空间。更多的热量通过管壁和壳体传至水中，降低表面温升。
附图说明
图1为现有技术中常见的热交换器。
图2为图1的部分放大剖视图。
图3为实施例结构示意图。
图4为实施例部分放大剖视图。
图5为图4的分解图。
具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图3、图4和图5所示，本实施例中的热交换器应用于燃气热水器中，具体包括壳体1、设于壳体1外壁的盘管及设于壳体内的内管，壳体1的外壁具有条形的第一凹槽11，壳体1的外壁设有紧贴设置有贴合板2，该贴合板2上成型有条形的第二凹槽21，该第二凹槽21与第一凹槽11对接拼合形成水管通道4。
第一凹槽11为多个并上下间隔布置，对应地，第二凹槽21也为多个并上下间隔布置。第一凹槽11之间成型有条形的第三凹槽22，对应地，第二凹槽21之间成型有条形的第四凹槽12，该第四凹槽12与第三凹槽22对接拼合形成空气夹层通道或真空通道，又或是隔热材料，隔热材料优选多孔材料。
如图3所示，内管3贯穿通过壳体1，该内管3与水管通道4通过弯管6连接。
贴合板2与壳体1的外壁焊接为一体，也可以通过螺钉、铆钉等连接构件连接为一体，又或通过卡扣结构连为一体。
将壳体1和水管通道4合为一体，两者之间无缝隙连接，可减少与外部空气的热交换，减少热损耗，提高热交换率，减少占用空间。更多的热量通过管壁和壳体1传至水中，降低表面温升。增加真空或空气层，减少与外部空气的热交换，进一步降低热损耗。
