Description

换热器、换热模块、换热装置以及热源单元
本申请要求于2014年12月11日递交的、申请号为201420783711.6、发明名称为“换热器、换热模块、换热装置以及热源单元”的中国专利申请的优先权，其全部内容通过引用并入本申请中。
技术领域

然而，上述的热源单元中的左右侧换热器的边缘在V形构造的上部间隔开。这样，仍然需要遮蔽板(或金属板)来连接两个换热器，从而导致了两个换热器之间的空间没有被有效地使用。

具体实施方式
下面通过实施例，并结合附图1-11，对本发明的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标号指示相同或相似的部件。下述参照附图对本发明实施方式的说明旨在对本发明的总体发明构思进行解释，而不应当理解为对本发明的一种限制。
如从本发明的背景技术中所了解的，本发明的设计要点在于对文献WO2011013672中的热源单元中所使用的换热模块的改进。具体地是由于在该文献中一对换热器在侧视图中被设置成大致V字状，这样就会造成在对置的空气换热器的弯曲部相互之间形成大致V字状的空间。显然，在上述文献中所述一对装配在一起的换热器主体部之间的空间且它们的相邻的弯曲部之间的空间都大致呈同一V字形， 也就是说它们之间的夹角相同，且通常在30-90°的范围内。最终，造成该一对换热器之间的V字形空间没有被有效地使用。由于他们之间夹角较大，上述V字形空间需要由被剪切成大致V字形的板体即遮蔽板封闭，防止空气或风穿过该V字形空间，从而影响换热效果。
在本发明中，提供了一种换热器、换热模块、换热装置和热源单元，它们成功地至少部分地解决了上述文献所提及的不足。因此，在下文将着重描述本发明对于换热器、换热模块、换热装置和热源单元所进行的改进。由于上述文献中所提及的热源单元中的诸如鼓风机、与换热装置连通的排水盘、容纳除换热装置之外的制冷循环组成部分的机械室等部件的布置也可以应用到本发明中，因此关于它们的具体描述可以参见该文献，不再在此进行详细描述。
从上述文献可知，传统的换热器一般为矩形，且需要钣金件来封闭V形侧面。在此需要说明的是，虽然上述文献将其称为V形侧面，但是如从上述文献和本发明的附图可知，在实际制造过程中，通常将其制造成大致梯形。因此，本发明将其称为梯形侧面，以使得更加符合实际情况。本发明的目的在于增加换热面积，满足不同的应用和安装要求。通过下述可知，在本发明中，通过折弯换热器使得在拼接之后，换热模块的侧面形成梯形或大致梯形，至少部分地替代钣金件封闭的梯形侧面。
根据本发明实施例的换热器、换热模块、换热装置和热源单元可以应用于商业空调系统，具体是用于热源单元中、风冷冷水机组或商用屋顶机中。通常，该换热装置包括至少一个换热模块，该至少一个换热模块具有垂直于左右两侧的大体梯形的至少一个侧面(由于以下简称为梯形换热侧部)，其中换热侧面中设置有集流管以及其上的换热管和/或翅片。
本领域技术人员可以理解，在换热装置具有多个换热模块100时，可以根据需要选择将换热装置设置为由多个同类型换热模块100组成或者采用本发明所述的不同类型的换热模块100的任意组合形式。
参见图1，在换热模块100的上端设置有顶板50，且在该顶板50与换热器1和2相对应的位置处设置有风机模块或单元30。在一个实施例中，从顶板50向上突出的方向上设置有圆筒状的出风口31，风扇罩32覆盖该出风口31的突出端面。该鼓风机30包括：螺旋桨式风扇，容纳在出风口31内；轴芯，与风扇罩32对置地安装，以及风扇马达，将该螺旋桨式风扇安装在旋转轴上。
当然，为了更好地固定换热模块100，还可以在换热模块100的底部设置有固定 其的支撑件或支撑框架(未示出)。在实际中，如图1所示，换热模块100的左右侧面不是严格意义上的V形侧面，而是在实际应用中为梯形侧面。如图所见，每个换热模块100在页面的左右两侧上具有两腰边之间的夹角θ的梯形换热侧面。
在此为了便于描述和说明，仅示出了其中所包含的换热部分或换热器/换热单元。
参见图2-3，示出了根据本发明的第一实施例的换热器以及由其组成的换热模块的示意图。具体参见图3，换热模块100包括折弯后的换热单元10和换热单元20，如下文所述的，换热单元10和换热单元20可以相同或不同。每一换热单元10或20可以由一个或多个换热器构成，在此为了简便，每一换热单元都图示和描述成单个换热器。在本发明的第一实施例中，换热器10和20设置成完全相同。
参见图2，在本发明的第一实施例中，换热器10包括集流管11、集流管12、换热管13和翅片14。在图2的页面内沿左右方向水平地延伸的多根换热管(以及翅片，如果设置有的话)构成了换热器10的主体部15，而在换热器10的两侧、相对于图2的页面的左右方向成角度α设置的多根换热管以及翅片构成了折弯部16和折弯部17。折弯部16具有大体梯形侧面，用于形成换热模块的梯形换热侧面(这将在下文进行描述)的一部分；而折弯部17具有大体四边形(在图中示出为平行四边形)的侧面，用于形成换热模块的另一梯形换热侧面的一部分。主体部15和折弯部16在直线Y处彼此连接，因为如在下文所描述的将以折弯轴线Y为轴线使折弯部16相对于图2的页面向外折弯，故将其称为折弯轴线Y。同理，主体部15和折弯部17在直线Y’处彼此连接，因为如在下文所描述的将以折弯轴线Y和Y’为轴线使折弯部16和17相对于图2的页面向外折弯，故将其称为折弯轴线Y和Y’。需要说明的是，在本实例中，折弯部16和17仅沿着其的折弯轴线Y和Y’折弯一次。
在图2所示的换热器10中，集流管11、12分别设置换热器10的最外侧，即在折弯部16的右侧和折弯部17的左侧。集流管11和集流管12的长度相等或者近似相等，但是如图所示他们相对彼此成一定角度或倾斜。多根换热管13间隔地且彼此平行地设置在集流管11和集流管12之间。在集流管11、12上分别设置有用以装配换热管13的多个槽。翅片14设置在相邻换热管13之间。在本示例中，将换热管13设置为扁管。
所述换热管13的两侧被以宽度方向为轴线折弯成例如角度α，其中所述换热管的折弯处分别大致在所述折弯轴线Y和Y’处，所述角度α在β/2-5°至β/2+5°的范围 内，其中β等于或小于梯形换热侧面的夹角θ。同理，可以以类似于换热器10的方式设置换热器20，使其与换热器10相同，在此不再累述。
在图中为了突出描述重点，省去了与之相关联的冷水机组单元或热源单元中的相关部件。鉴于本发明的主要设计在于换热装置，这样的省略不会影响本领域技术人员对本发明的理解且也不会使得本发明的公开内容的不完整。
在本领域中熟知，换热装置包括至少一个换热模块。可以明白，本发明所述的换热装置可以包括一个或者任意几个(例如，两个、三个、五个等)换热模块和相应数量的风机模块或风机单元，其中多个风机模块或风机单元构成了一个风机装置或风机系统。当然，每个风机单元或模块也可以是一个风机或更多个风机。
通常，换热模块包括两个拼接在一起的换热器。当然，本领域技术人员可以明白，换热模块的组成方式不限于上述类型，换热模块的组成方式还可以包括以下几种：换热模块可以包括单个换热单元，其梯形换热侧面通过折弯该单个换热单元的一部分(例如折弯单个平板型换热器的两端)来形成。或者，换热模块还可以由多个换热单元形成，其中该梯形换热侧部由单个换热单元来形成，该梯形换热侧面被装配到换热模块的其他部分(例如与之相邻的其他换热器)上。或者，换热模块中还可以包括相对彼此装配在一起的一个换热单元和一个支撑构件(例如金属板支撑构件)，所述换热单元被折弯以形成所述梯形换热侧面，所述梯形换热侧面装配到所述支撑构件上。原则上，每个换热单元为传统意义上的单个换热器，即具有两根集流管、以及在它们之间间隔地且平行地延伸的多根换热管(例如扁管，如果可以的话，扁管上可以设置有多个翅片)。当然也可以包括多个换热器。以下，为了描述简便，将单个换热单元简称为换热器。
如图2-3所述，在本发明的第一实施例中，每一换热模块包括两个相同的换热器，即换热器10和20相同。在该换热模块中，每一梯形换热侧面由拼接在一起的两个换热器的折弯部形成。
具体地，在折弯部16、17中的换热管13被相对于主体部15中的换热管倾斜和折弯，使得主体部15所在的平面垂直于或大体垂直于所述两个折弯部中的每一个折弯部所在的平面。
以图2为例，说明两侧具有折弯部的换热器10的折弯方式为：先进行扁管13的折弯，再进行换热器10的本体折弯。具体折弯步骤如下：首先，将每根扁管13的两侧(如图示中扁管的左右两侧)，以该扁管的宽度方向(即页面中的前后方向)为轴 线，将扁管折弯成角度α，并将折弯后的扁管13依次插入集流管11、12的槽(未示出)内。然后，通过调整扁管的位置，使所有扁管13在任一侧的折弯处大致在一条线上，即，如图2所示的折弯轴线Y和Y’上。这样，换热器10就形成了主体部15和折弯部16和17。在相邻扁管之间插入翅片14，然后放进钎焊炉里钎焊成整体。最后，将折弯后的换热器中的折弯部16和17以折弯轴线Y和Y’为折弯轴线，沿着大致垂直于主体部15的方向折弯(即换热器进行本体折弯)，使得主体部15与折弯部16和17垂直或大致垂直(参见图3)。
如图2和3所示，主体部15为换热模块100中的矩形侧面，换热器10的折弯部16和17分别与另一换热器20的两个折弯部构成了换热模块100的一个梯形换热侧面。然而，可以明白，上述主体部15为矩形形状仅是一种示例，其可以根据需要被选择成任何合适的形状，例如大致方形、梯形、平行四边形形状。
在折弯部16中，最下边的一根扁管长度最短，最上端的扁管长度最长，扁管与扁管之间的间距为L。并优选地，使得折弯部中的扁管的长度由下往上以2Ltgα依次递增。为了加工方便，每根扁管的长度可以稍作调整。
在折弯过程中，优选地，使扁管的折弯角度α大致为梯形侧面(即折弯部16)的两腰边之间的夹角β的角度的一半，但是通常只要在β/2-5°至β/2+5°的范围内即可。折弯轴线Y与集流管12之间的夹角β的角度优选地使之大致等于或小于换热梯形侧面的顶角θ。当然，上述的折弯方式仅是本发明的一个示例，当然本领域技术人员可以根据需要选择其他的方式(例如以另一角度)进行折弯。
为了装配方便，在集流管11或12一侧的扁管13的端部可以通过折弯使得扁管13垂直或大致垂直地插入集流管12的槽内。当然，本领域技术人员还可以使扁管13的折弯处(即大致折弯轴线Y和Y’所在的位置)大致或基本上没有翅片，这样更容易将换热器10折弯，并还能使折弯半径尽可能的小。
本领域技术人员可以理解，在本实施例中，由于换热模块100中的右侧换热器10和左侧换热器20大致相同或对称，因此，换热器20的结构和折弯的原理与换热器10的结构与原理大致相同，在此不再赘述。
再次参见图3，换热器10和换热器20通过彼此的集流管相互连接，以形成换热模块100。即，换热器10中的集流管11与换热器20中的集流管22相连接，换热器10中的集流管12与换热器20中的集流管21相连接，使得换热器10和换热器20的折弯部分别用作换热模块100的两个梯形换热侧面，这样就增加了换热面积。本领域 技术人员可以根据需要选择具体设置方式，不限于上述的方式。以上列举仅是为了示例性的说明，不能理解为对本发明的一种限制。
参见图4-6，示出了根据本发明的第二实施例的换热模块，该换热模块由两个不对称的换热器60、70构成。换热器60具有矩形的主体部65以及大体平行四边形的两个折弯部66、67。在两个折弯部66、67中，扁管的长度相同。其的折弯步骤与第一实施例所述的相同，其不同之处仅在于折弯出两个平行四边形的折弯部。故仅对折弯步骤进行简单描述。
换热器60的折弯步骤简述如下：
先进行扁管的折弯再进行换热器60的芯体折弯，换热器芯体组装前，每根扁管的两侧需要以宽度方向为轴线，分别折弯成α角。优选的α大致等于梯形侧面的V形夹角β的一半，在折弯部66、67中每一根扁管都具有相同的长度。但是为了加工方便，每根扁管的长度可以稍有调整。
另一换热器70具有矩形的主体部75及两个大致梯形的折弯部76、77。换热器70的折弯步骤如下：
先进行扁管的折弯再进行换热器70的芯体折弯，换热器芯体组装前，每根扁管的两侧需要以宽度方向为轴线，分别折弯成α角。优选的α大致等于梯形换热侧侧面的V形夹角β的一半，在每一折弯部76、77中最下边一根扁管最短，最上端扁管长度最长，扁管长度由下往上以2L*tgα依次递增。也就是，在换热器70中，每一扁管长度由下往上以4L*tgα依次递增，。为了加工方便，每根扁管的长度可以稍有调整。
图7示出了根据本发明的第三实施例的换热模块。该换热模块包括两个不对称的换热器60和40。该换热器60与图6中的换热器60相同，故用相同的参考标号显示(下同，故不再说明)。
另一换热器40是一种常规的换热器，其仅具有与换热器60相同或大体相同的主体部。其不同之处在于矩形主体部的两端分别设置有集流管。
可以理解，在将换热器60和40拼接之后，在换热模块的每一梯形换热侧面都会具有一个大体三角形或三角形的区域没有设置换热管以及翅片。故将其称为漏风区域，其可以用图7所示的挡风板或挡风件80进行遮挡。关于挡风板80的具体形状、制造材料等可以根据需要进行选择，在此不再详述。
图8示出了根据本发明的第四实施例的换热模块。该换热模块包括两个对称的换热器90。该换热器90与图6中的换热器60不同仅在于一侧设置有折弯部。折弯方 式或步骤与图6的换热器60相同。
可以理解，在将两个换热器90拼接之后，在换热模块的每一梯形换热侧面都会具有一个大体矩形或三角形的区域没有设置换热管以及翅片。故将其称为漏风区域，其可以用图8所示的挡风板或挡风件80进行遮挡。关于挡风板80的具体形状、制造材料等可以根据需要进行选择，在此不再详述。
图9和10示出了根据本发明的第五实施例的换热模块和换热器。该换热模块包括两个相同的换热器110。具体参见图9，示出了该换热器110的具体结构。虽然换热器110仅在一侧具有折弯部，但是其通过将换热器110的芯体沿着两个不同的折弯轴线Y和Y”折弯两次形成。
具体折弯步骤和折弯方式如下：
首先，将每根扁管的一侧(如图示中扁管的右侧)，以该扁管的宽度方向(即页面中的上下方向)为轴线，将扁管折弯成角度α，并将折弯后的扁管依次插入两侧的集流管111、112的槽(未示出)内。然后，通过调整扁管的位置，使所有扁管在右侧的折弯处大致在一条线上，即，如图9所示的折弯轴线Y上。这样，换热器110就形成了主体部115和折弯部116。在相邻扁管之间插入翅片，然后放进钎焊炉里钎焊成整体。最后，将折弯后的换热器中的折弯部116以折弯轴线Y为折弯轴线，沿着大致垂直于主体部115的方向折弯(即换热器进行本体折弯)，此后，再沿着另一折弯轴线Y”使折弯部116相对于主体部115折弯预定角度，形成了另一折弯部117，使得主体部115与折弯部116垂直或大致垂直(参见图10)。
折弯轴线Y”可以偏离轴线Y，可以在折弯轴线Y两侧。优选的，Y”和Y之间距离小于等于200mm。如果将两个换热器110拼接后，形成有漏风区域，则可以在漏风区域处设置挡风板。
图11示出了根据本发明的第六实施例的换热模块。该换热模块四个拼接在一起的换热器120、130。
所述四个换热器中的两个换热器120具有相同的尺寸并且具有大体四边形的侧面，所述四个换热器中的另外两个换热器130具有相同的尺寸并且具有梯形的侧面。每个换热器120、130包括两根集流管，所述两根集流管设置在该换热器的两个相对侧上。多根换热管连通于集流管(在一些实例中，如图示，换热管倾斜地连通于集流管)，且间隔地设置在换热器的侧面中并彼此大体平行地在其中延伸。所述换热管为扁管，并且在扁管上设置有翅片。
虽然本发明的上述实施例都采用先折弯扁管成例如角度α，之后在相对于换热器的主体部折弯所述已经折弯的扁管使其垂直于主体部，从而最终形成换热装置的梯形侧面，但是也可以使用其他的方式来制造出具有类似结构的换热器。例如通过绕制换热管使得其在上述的换热器的主体部和折弯部之间部分地或全部地连续地蜿蜒延伸，来获得与本发明的换热器相同或相类似的结构。也就是说，可以通过绕制一根或多根换热管成大致U形或蜿蜒结构，来获得与本发明相类似的换热器。在可行的情况下，这种绕制方式可以省去使用集流管。
本发明的优点在于，不需要通过增大HVAC系统便可以实现增加换热装置的换热面积。它可以通过增加换热器的换热性能来增加HVAC系统能效(降低消耗功率)。如果HVAC不需要更高的能效和更大的换热性能，它还可以用于减少系统中的换热器的数量，使得整体HVAC系统更加紧凑，并具有较低的制造和安装成本。
以上仅为本发明的一些实施例，本领域普通技术人员将理解，在不背离本总体发明构思的原则和精神的情况下，可对这些实施例做出改变，本发明的范围以权利要求和它们的等同物限定。
