本发明涉及U形弯曲热交换管类型的热交换器，更具体而言，涉及一种将热交换管和U字管构成为一体的多个U形弯曲热交换管设置在热交换器主体，以便在低温水与热源之间产生热交换的U形弯曲热交换管类型的热交换器。

Description

U形弯曲热交换管类型的热交换器
技术领域
本发明涉及U形弯曲热交换管类型的热交换器，更具体而言，涉及一种将热交换管和U字管构成为一体的多个U形弯曲热交换管设置在热交换器主体，以便在低温水与热源之间产生热交换的U形弯曲热交换管类型的热交换器。
背景技术
热交换器将温度相互不同的加热液体和被加热液体进行交互来实现热传递，其用于通过对循环在锅炉或热水器中的低温水进行加热，来使低温水加热成温水或取暖水而供给。
另外，热交换器通过将布置在主体内部的多个热交换管连接到主体的两侧面，使低温水以Z字形方向进行循环。并且，该热交换器根据连接件的种类大致分为U字管方式及水套方式。
如图1所示的U字管方式是已被包括韩国公开专利第2010-0032543号的许多文件公开的方式，而且公开了将多个热交换管30布置在热交换室40内部并通过主体侧面的U字管连接所邻接的管道的技术。
反而，如图2所示的水套方式是已被包括韩国公开专利第2010-0115601号的许多文件公开的方式，而且公开了通过并列流道盖31(水套)连接插进在第一固定板21及第二固定板22之间的多个热交换管道10的技术。
但是，U字管方式具有因U字管突出于主体的外侧而使热交换器的整体尺寸增加，并且由于向外部所露出的U字管的放热而产生热损失，从而降低热效率的缺点。
并且，水套方式虽然能够弥补U字管方式的缺点，但是不能满足高性能的耐压测试标准。即，水套方式具有由于在热交换器侧面的压力膨胀和在批量生产中不均匀的硬钎焊等的理由发生压力变形及烧坏的缺点。

发明要解决的问题
本发明是为了解决上述问题而提供一种热交换器，该热交换器是通过将U字管不让向热交换器主体的外部露出并使水套的使用最小化，来减小整体尺寸和防止热损失，并且具有高的内压性能的U形弯曲热交换管类型。
用于解决问题的方案
为此，根据本发明的U形弯曲热交换管类型的热交换器的特征在于，包括：热交换器主体，由前方侧板、后方侧板、左侧侧板及右侧侧板包围并且其上部和下部被开放，以便使热源通过；多个U形弯曲热交换管，插进并组装于所述左侧侧板和右侧侧板之间，并分别包括相互平行布置的两个热交换管及相连接所述两个热交换管的一侧端部的U字管；以及多个水套，通过结合于所述左侧侧板及右侧侧板中的至少一个的外侧面并相连接所邻接的两个热交换管的开放的端部，使低温水沿着所述多个U形弯曲热交换管进行循环，其中，所述U形弯曲热交换管的U字管固定于所述左侧侧板或右侧侧板的内侧面，所述两个热交换管的另一端部插进到与固定有所述U字管的侧板相反的侧板而连接到所述水套。
此时，所述U形弯曲热交换管优选为其端面具有椭圆形的椭圆形管道。
并且，在所述左侧侧板及右侧侧板中的至少一个设置有用于插进并固定所述U形弯曲热交换管的U字管的U字管固定部，并且，所述U字管固定部优选为所述右侧侧板的一部分从内侧到外侧突出而形成于所述右侧侧板的内侧面的组装槽。
并且，所述U形弯曲热交换管优选地包括：CO减少热交换管，具有设置为从所述热交换器主体的上端部向下侧隔开一定距离并相互平行布置的第一CO热交换管及第二CO热交换管；以及多个主热交换管，设置于所述CO减少热交换管的下侧并在外周面设置有热交换销。
并且，优选地，构成所述第一CO热交换管的两个热交换管中的一个热交换管固定于所述前方侧板F，并构成所述第二CO热交换管的两个热交换管中的一个热交换管固定于所述后方侧板。
并且，所述U形弯曲热交换管类型的热交换器还包括：辅助热交换管，其设置于所述CO减小热交换管的上侧，并且，构成所述辅助热交换管的两个热交换管优选地分别固定于所述前方侧板及后方侧板。

更详细的，作为一实施例，热交换器主体110构成显热交换器(还称为“1次热交换器”)的主体，其包括：前方侧板F、后方侧板B、左侧侧板L及右侧侧板R。
该多个侧板F、B、L及R在布置于前后左右正确位置的状态下，通过焊接等来相结合。优选地，如图6所示，通过分别穿孔左侧侧板L及右侧侧板R的一部分，在借助所突出的侧板连接件113按前方侧板F和后方侧板B而固定的状态下，简单地进行焊接。
如上所述，分别开放所组装的热交换器主体110的上部和下部，以便使从布置在上部的燃烧室所流入的高温的燃烧气体向下排放。此时，在热交换器主体110的上部设置有朝下式预混气体燃烧器。
即，一般的冷凝燃烧从其上部开始布置有预混气体燃烧器、燃烧室、显热交换器、潜热交换器及排放部。作为一实施例，本发明的热交换器主体110用作显热交换器。
接着，U形弯曲热交换管120在热交换器主体110的内部中插进并组装于左侧侧板L与右侧侧板R之间。所述的U形弯曲热交换管120设置为多个并且每个U形弯曲热交换管120构成热交换用管道单元。
如图7所示，多个U形弯曲热交换管120(120a、120b及120c)分别包括相互平行布置的两个热交换管121(121a、121b及121c)及相连接所述两个热交换管121的一侧端部的U字管122(122a、122b及122c)，从而整体上具有弯曲为“U”字形的形状。
在热交换器的组装工程之前，通过预先将U字管122插进并焊接于两个热交换管121中，制成每个U形弯曲热交换管120。并且，将完成的所述U形弯曲热交换管120组装于热交换器主体110的内部(即，不让向外侧露出)。
上述的U形弯曲热交换管120分为包括：用来降低一氧化碳的CO减小热交换管120a、用来提高热效率的主热交换管120b及用来增强的辅助热交换管120c的三种。
如在下文中再详细说明的一样，CO减小热交换管120a布置于中端，主热交换管120b布置于下端并且辅助热交换管120c设置于上端，从而起到各自的作用。
另外，图3及图4中，U形弯曲热交换管120的所开放的端部都同一布置为朝向一侧(例如：左侧侧板)。由此，通过将多个水套130集中附着于一侧面来提高批量生产性。
但是，与附图不同的，多个U形弯曲热交换管120中有几个U形弯曲热交换管120所开放的端部可以沿与另外U形弯曲热交换管120不同的方向布置(例如：右侧侧板)。在此情况下，多个水套130也根据U形弯曲热交换管120设置方向分散到一侧和另一侧。
接着，水套130用于相连接一个U形弯曲热交换管120和邻接于其的另一个U形弯曲热交换管120，进而继续连接多个U形弯曲热交换管120。
具体的，通过将构成U形弯曲热交换管120的两个热交换管中的一个热交换管连接到构成邻接的另一个U形弯曲热交换管120的两个热交换管中的一个热交换管，使两个U形弯曲热交换管120相连接。
由此，通过多个水套130连接多个U形弯曲热交换管120，使低温水经过所有的U形弯曲热交换管120而依次的流动(附图中的箭头符号表示低温水的流动方向)。
但是，水套13中设置于最上部的左右两个水套130构成为分别具有“┐”字形状及“一”字形状，以便通过增强除了管道的连接点以外的部分，来防止由在燃烧器燃烧时所发生的热影响导致的热变烧坏。
同时，优选地，在水套130自身上还形成取暖水流道，以便由水套130还吸收在燃烧器燃烧时所发生的热并防止左侧侧面L的变形和热冲击。
上述的水套130又称为“流道盖”或者“水箱”，若将水套130通过硬钎焊等固定于热交换器主体110的侧板，则在侧板之间形成流道。由此，连接插进于侧板中的U形弯曲热交换管120的所开放的端部。
水套130根据U形弯曲热交换管120布置方向结合于左侧侧板L及右侧侧板R中的至少一个的外侧面。如图3和图4所示，在U形弯曲热交换管120的布置方向统一的情况下，则多个水套130都组装于左侧侧板L。
但是，如上所述，根据所述U形弯曲热交换管120的开放的端部朝向的方向，水套130也是可以设置于左侧侧板L及右侧侧板R。即，若多个U形弯曲热交换管120分别设置为朝向左/右，则水套130分散设置于左侧侧板L及右侧侧板R。
如上所示，本发明的特征在于，U形弯曲热交换管120的U字管122固定于左侧侧板L或右侧侧板R的内侧面，并且两个热交换管121的另一端部插进到与固定有所述U字管122的侧板相反的侧板而连接到所述水套130。
比如，如图3及图4所示，U形弯曲热交换管120的U字管122固定于右侧侧板R的内面并且热交换管121的开放的端部固定于左侧侧板L，由此，水套130也是组装于左侧侧板L的外侧面。
由此，如图1所示的现有技术的U字管突出且露出于热交换室40的外部，反而本发明通过将U字管122位于热交换器主体110的内部，来减小热交换器的整体尺寸并防止由向外部的放热导致的热效率降低。
并且，如图2所示的现有技术的热交换管的两端部都开放，反而本发明的热交换管121只开放一端部(另一端由U字管被连接)而减小连接开放的端部的水套130的数量并提高内压性能。
但是，上述的U形弯曲热交换管120优选为其端面具有椭圆形的椭圆形管道。即，优选地，两个热交换管121及U字管122都构成为其端面具有椭圆形的管道。作为材料能够采用不锈钢等的各种材料。
由公知的整个努塞尔数可知，与端面为圆形的管道等相比，端面为椭圆形(或卵形)的椭圆形管道具有高的热导率，从而更加高效率。
同时，端面为椭圆形的U形弯曲热交换管120与端面为圆形的管道相比具有约40％的摩擦系数，由此减小由于管道的摩擦压力损耗并实现热源的顺利流动。
并且，本发明优选地在构成热交换器主体110的左侧侧板L及右侧侧板R中的至少一个上设置供U形弯曲热交换管120的U字管122插进并固定的U字管固定部111。
U字管固定部111可以采用能够包围U字管122的外周面的同时固定于侧板上的夹具或在上部布置有U字管122并支撑U字管122的支架及供U字管122插进的组装槽等各种类型。
尤其，如图8放大所示，作为用于U字管122的固定部111采用上述的组装槽时，仅将U字管122插进于组装槽，则由一次按压方式实现组装。
上述的组装槽111通过加压右侧侧板R及/或左侧侧板L的一部分来成型，以便右侧侧板R及/或左侧侧板L的一部分从内侧到外侧突出，并且，根据需要对插进于组装槽的U字管122通过硬钎焊等进行焊接。
由此，使得U形弯曲热交换管120的U字管122不让向热交换器主体110的外部露出并使简单的组装，从而能够特别提高热交换器的批量生产性。
进而，优选地在前方侧板F及后方侧板B上形成长度较长的长槽112，以便将U形弯曲热交换管120的热交换管121插进于长槽112内。长槽112作为用于热交换管121的一种组装件，通过长槽112能够由可拆卸方式组装U形弯曲热交换管120并增强热交换器主体110。
并且，本发明作为U形弯曲热交换管120优选地包括根据其固有的作用所区分的CO减小热交换管120a和主热交换管120b及辅助热交换管120c。
CO减小热交换管120a包括平行布置的两个U形弯曲热交换管120即第一CO热交换管及第二CO热交换管，并且设置为从热交换器主体110的上端部向下侧隔开一定距离(例如：热交换器主体的中间高度)。
上述的CO减小热交换管120a防止经过燃烧器的燃烧室流入的高温的燃烧气体流入到热交换器主体110内部之后直接开始热交换，并且作为热交换管道用。
燃烧气体多量包含CO(一氧化碳)，因此，若在CO与O2进行反应而成为CO2的化学反应发生之前急剧实现热交换，则燃烧气体急剧被冷却并不会发生化学反应，从而CO直接被排放。
由此，本发明具有使燃烧气体的温度平缓降低的平缓的温度梯度，以便形成将CO化学变化为CO2的温度，从而减小有害物质的放出。
尤其，构成第一CO热交换管120a的两个热交换管121a中的一个热交换管固定于前方侧板F，并相向地构成第二CO热交换管120a的两个热交换管121a中的一个热交换管固定于后方侧板B。
若将CO减小热交换管120a设置成如上所示的布置方式，则第一CO热交换管及第二CO热交换管分别固定于前方侧板F及后方侧板B的同时提供增强力，从而在高温的动作情况下也提高内压性能。
进而，向燃烧器的下侧隔开一定距离的同时在第一CO热交换管和第二CO热交换管之间形成间隔，由此能够防止燃烧气体的温度急剧降低而减小CO发生，并使燃烧气体顺利流动。
接着，主热交换管120b用来与从设置于热交换器主体110的上部的燃烧室的燃烧器所发生的热源进行主要的热交换，在其热交换管121b的外周面附着有用于提高热传率的热交换销HE_F。
上述的主热交换管120b设置于CO减小热交换管120a的下部(即，以燃烧气体的流动方向为基准的下流)，并且具有多个(例如：三个)U形弯曲热交换管120向左右并列配置的结构，以便提高热传率。
由于在热交换管121b的外周面附着有热交换销HE_F，而虽然主热交换管120b不插进于前方侧板F及后方侧板B的长槽112，但是固定于左侧侧板L及右侧侧板R中的任意个组装件111。
接着，辅助热交换管120c用来减小CO并增强较低的热交换及热交换器主体110的内压，设置于CO减小热交换管120a的上侧。
辅助热交换管120c的构成中两个热交换管121c分别固定于所述前方侧板F及后方侧板B，并且U字管122c固定于左侧侧板L或右侧侧板R。
上述的辅助热交换管120c构成为一个的U形弯曲热交换管120，但辅助两个热交换管121c分别固定于前方侧板F及后方侧板B，由此U字管122c的长度与CO减小热交换管120a或主热交换管120b的U字管122a、122b的长度相比更长。
并且，辅助热交换管120c的U字管122c也是插进于形成在左侧侧板L及/或右侧侧板R的组装槽111(即，组装件)，并且两个热交换管121c插进并组装于形成在前方侧板F及后方侧板B的长的长槽112。
以上，对本发明的特定实施例进行了详细说明。但是，本发明的思想和范围不限于这种特定实施例，在不变更本发明的主旨的范围内能够进行多种修改和变形，这一点对于本发明所属技术领域的普通技术人员而言是可理解的。
因此，以上记载的实施例仅仅是为了向本发明所属技术领域的普通技术人员说明本发明的范畴而记载的，在各方面仅仅是示例性的，不应理解为是限定性的，本发明仅由权利要求的范畴来定义。
