Description

一种翅片式蒸发器
技术领域
本发明涉及一种蒸发器,尤其涉及的是一种翅片式蒸发器。
背景技术
冰箱的换热器包括蒸发器和冷凝器,提高换热器的换热效率是提高冰箱制冷系统效率,降低能耗的有效手段。其中蒸发器常用翅片式蒸发器,传统的翅片式蒸发器的翅片与蒸发管之间采用过盈配合的方式固定在一起,换热效果较差,换热效率不高。
发明内容
本发明的目的在于克服现有技术的不足,提供了一种翅片式蒸发器,以期实现换热效果高的目的。
本发明是通过以下技术方案实现的:
一种翅片式蒸发器,包括蒸发管和翅片,所述翅片上设有翻边孔,所述翅片的翻边孔与所述蒸发管穿插连接,所述翅片由相连接的基层和钎料层构成,所述翅片在所述翻边孔一端设有翻边,所述翻边向所述蒸发管表面翻折且与所述蒸发管表面相贴合,所述翻边在面向所述蒸发管的一侧设有第一钎料层,所述翻边通过第一钎料层与所述蒸发管外表面焊接在一起。
所述蒸发管外表面设有一层钎料膜。
通过炉中钎焊工艺将所述翻边的第一钎料层与所述蒸发管外表面焊接在一起。
所述蒸发管的截面形状为圆环形。
本发明相比现有技术具有以下优点:
本发明提供的一种翅片式蒸发器,其翅片的翻边通过第一钎料层与蒸发管钎焊在一起,利用钎料在高温环境下的湿润性和渗透作用将翅片与蒸发管间的配合气隙填补,且钎料的导热效果远高于管道间的过盈配合,提高了翅片的传热效果,增加了蒸发器的换热效率。
附图说明
图1是本发明的结构示意图。
图2是本发明的剖面结构示意图。
图中标号:1翅片,11基层,12钎料层,13翻边,14第一钎料层,2蒸发管,21钎料膜。
具体实施方式
下面对本发明的实施例作详细说明,本实施例在以本发明技术方案为前提下进行实施,给出了详细的实施方式和具体的操作过程,但本发明的保护范围不限于下述的实施例。
参见图1、图2,本实施例公开了一种翅片式蒸发器,包括蒸发管2和翅片1,蒸发管2的截面形状为圆环形。翅片1上设有翻边孔,翅片1的翻边孔与蒸发管2穿插连接,翅片1由相连接的基层11和钎料层12构成,翅片1在翻边孔一端设有翻边13,翻边13向蒸发管2表面翻折且与蒸发管2表面相贴合,翻边13在面向蒸发管2的一侧设有第一钎料层14,翻边13通过第一钎料层14与蒸发管2外表面焊接在一起。
具体设置中,翻边13加工时,首先在翅片1上冲切小孔,在对小孔进行扩孔翻边成形从而得到该翻边13,加工工艺简单方便。
其中,焊接工艺优选炉中钎焊工艺,通过炉中钎焊工艺将翻边13的第一钎料层14与蒸发管2外表面焊接在一起。
该蒸发器的翅片1为由基层11和钎料层12构成的复合结构,蒸发管2与翅片1的翻边孔相穿插配合后,通过芯棒的拉胀或者插胀作用进行胀管作业,使得蒸发管2外径增大与翅片1的翻边孔接触、紧固,胀管后的蒸发器组件进入恒温钎焊炉进行“炉中钎焊”,通过钎料将翅片1与蒸发管2焊接在一起,利用钎料在高温环境下的湿润性和渗透作用将翅片1与蒸发管2间的配合气隙填补,增加翅片式蒸发器的换热效果。且钎料的导热效果远高于管道间的过盈配合,提高了翅片1的传热效果,增加了蒸发器的换热效率。蒸发管2的表面设有一层钎料膜21,通过上述类似的工艺将蒸发管2与翅片1钎焊在一起。
以上仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
