一种高效紧凑型翅片式气体冷却器
本技术涉及一种冷却器,尤其涉及一种高效紧凑型翅片式气体冷却器。
技术介绍
国内大部分厂家冷轧生产线基本采取进口,生产线上关键炉内管式气体冷却器大部分都是进口设备,由于进口设备工艺复杂、转化难度大、周期时间长和成本高等问题,不能满足生产需要。申请人现有针对冷轧线炉用管式气体冷却器如图4所示,但是其具有不足之处如:结构相对比较复杂,制作工艺要求较高;其中冷却器泄漏问题非常关键,处理不好在使用中气水混合会造成炉内气体纯度不够及冷轧板面存在缺陷,因此急需一种使用更加安全、使用寿命更长的新型管式气体冷却器。
技术实现思路
为了解决上述技术所存在的不足之处,本技术提供了一种高效紧凑型翅片式气体冷却器。为了解决以上技术问题,本技术采用的技术方案是:一种高效紧凑型翅片式气体冷却器,包括箱体,所述箱体为长方体,长方体的四面由前端管箱、上侧板、后端管箱和下侧板围成环形,所述前端管箱后方分别连接有管板和密封板;所述前端管箱上设置有冷水进口和热水出口,前端管箱中间通过水平隔板将前端管箱分为上、下两个空间;所述管板上连接有U形的换热管,所述换热管两端通过管板与前端管 ...
