具体实施方式
下面通过实施例，并结合附图1-9，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。
参见图1，示出了根据本发明的第一实施例的第一换热器系统110的结构示意图。具体地，该第一换热器系统110包括从上到下依次布置的上部集流管10、中间集流管30和下部集流管20。上部集流管10与中间集流管30之间设置有第一换热管41并且中间集流管30和下部集流管20之间设置有第二换热管42。
如图所示，中间集流管30具有相互彼此独立的第一腔体31和第二腔体32。在 制冷剂的循环过程中(图1中的箭头示出了制冷剂流动的方向，以下均采用这种方式示出制冷剂流动的方向，不再对此详述)，所述上部集流管10中的制冷剂从第一换热管41向下流动到所述第一腔体31中，经由第一连通部件51流入到下部集流管20的腔体中，此后所述制冷剂从第二换热管42向上流入到所述第二腔体32中，进而经由第二连通部件52返回流入到上部集流管10中。
在此，需要说明的，第一连通部件51和第二连通部件52可以是起连通作用的连通管或接管。优选地，如图1所示，所述第一连通部件51是设置在下部集流管20和中间集流管30之间的至少一个圆管或扁管，并且所述圆管或扁管与第二换热管42排列成一排设置在下部集流管20和中间集流管20之间。所述第二连通部件52是设置在上部集流管10和中间集流管30之间的至少一个圆管或扁管，并且所述圆管或扁管与第一换热管41排列成一排设置在上部集流管10和中间集流管30之间。
所述上部集流管10和中间集流管30以及它们之间的第一换热管41构成第一换热器，所述中间集流管30和下部集流管20以及它们之间的第二换热管42构成第二换热器。在本发明中，为了说明的目的，将第一换热器称为冷凝器，而将第二换热器称为蒸发器。当然，本领域技术人员可以根据需要将第一和第二换热器设置成冷凝器、蒸发器或其他类型的换热器，本发明对此不做任何限制。
第一换热管41和第二换热管42可以是任何类型的换热管。通常，第一换热管41和第二换热管42被选择成圆管和扁管中的任一种。在同一换热器系统中，第一换热管41和第二换热管42不必设置成同一种类型的换热管，例如不必都是圆管或扁管，可以是其中的一种是圆管，而另一种是扁管，也可以是第一和第二换热管41、42中的一部分是圆管，而另一部分是扁管。也就是说，本文所述的第一和第二换热管41、42可以根据需要设置成任何类型的可行的换热管，本发明对此不做任何特殊限制。
另外，相邻的两根第一换热管41或相邻的两根第二换热管42之间可以设置有翅片，而不必考虑换热管的类型。
可以理解，如果将第一换热管41和第二连通部件52例如都设置成是圆管和/或扁管；那么可以将第一换热管41和第二连通部件52排列成一排设置在上部集流管10和中间集流管30之间，如图1所示。同理，如果将第二换热管42和第一连通部件51例如都设置成是圆管和/或扁管；那么可以将第二换热管42和第一连通部件51排列成一排设置在下部集流管20和中间集流管30之间，如图1所示。这样做可以简化第一换热器和/或第二换热器的制造工艺和制造难度，并且能够减少第一换热器和/ 或第二换热器的厚度，增加换热器的美观等作用。
如图1所示，在第一换热器中，多根第一换热管41设置在第一换热器的左侧，而第二连通部件52设置在第一换热器的右侧。另外，在第二换热器中，多根第二换热管42设置在第二换热器的右侧，而第一连通部件51设置在第二换热器的左侧。可以理解，本领域技术人员可以根据需要设置第一换热管41和第二连通部件52的相对位置，而不必限制成如图所示的那样，例如可以将第一换热管41设置成位于中间，第二连通部件52位于其的两侧。这也适用于第二换热管42和第一连通部件51，在此不再详述。
通过设置一主隔板61将中间集流管30分割成彼此独立的第一腔体31和第二腔体32。可以理解，主隔板61的形状可以设置成任何适当的形式，只要保证分隔出第一腔体31和第二腔体32即可，不限于图1所述的形式。例如主隔板61可以设置成从中间集流管30的上部倾斜地、竖直地、弯曲地或蜿蜒地延伸至中间集流管30的下部。
另外，需要说明的是，图1仅示出了一个制冷剂循环。当然，还可以将第一换热器系统设置成具有多个制冷剂循环，即在增加上部集流管10、中间集流管30和下部集流管20的纵向长度的情况下，在图1所示的结构布置的两侧根掘需要设置重复的结构单元，以实现上述的目的。
通过设置如图1所示的弯折型的主隔板61，沿着中间集流管30的纵向方向将其分隔成两个腔体，即第一腔体31和第二腔体32。
在第一换热器为冷凝器且第二换热器为蒸发器的情况下，以扁管作为换热管为例说明本发明的第一换热器系统在制冷时的工作原理。具体地，冷凝器中的制冷剂气体放热后，变为液体制冷剂，因重力的影响从放热扁管(第一换热管41)流下；在流入到蒸发器中之后在蒸发器内吸收热量，变为气体制冷剂，从吸热扁管(第二换热管42)流上去，并最终流入到冷凝器中；如此循环，达到了制冷的作用。
在此需要说明的是，图2-7所示的根据本发明的第一实施例的第二至第七换热器系统都是第一换热器系统的变形例。因此，关于第一换热器系统所作的结构设置或说明都适用于它们，故在此不再详细说明它们的相同之处，而仅着重说明它们与第一换热器系统的不同之处。
参见图2，示出了根据本发明的第一实施例的第二换热器系统120的结构示意图。通过比较图1和2可知，该第二换热器系统120与第一换热器系统110的不同之处在于中间集流管30内的腔体的分隔方式不同，其余部分均与第一换热器系统110 相同。
具体地，通过从中间集流管30的左端沿中间集流管30的纵向方向延伸至所述中间集流管30的右端的主隔板621以及设置在主隔板621和中间集流管的上壁和/或下壁之间的至少一个副挡板622、623将中间集流管30的腔体分隔成所述第一腔体31、所述第二腔体32和两个流通腔33和34。
在此，需要说明的是，副挡板622、623的设置方式可以是从中间集流管的上部或下部倾斜地、竖直地、弯曲地或蜿蜒地延伸至主隔板621，只要能够分隔出第一腔体和第二腔体即可。本发明对此不做限制。
在本示例中，第一腔体31和第二腔体32分别通过对应地设置在主隔板621上的第一开口71和第二开口72与相对应的连通腔33、34连通。
在第二换热器系统120的制冷剂的循环过程中，所述上部集流管10中的制冷剂从第一换热管41向下流动到所述第一腔体31中，之后经过第一开口71流入到流通腔33中。流通腔33中的制冷剂经由第一连通部件51流入到下部集流管30的腔体中，此后所述制冷剂从第二换热管42向上流入到所述第二腔体32中，该第二腔体32中的制冷剂经过第二开口72流入到另一流通腔34中，进而经由第二连通部件52返回流入到上部集流管10中。
参见图3，示出了根据本发明的第一实施例的第三换热器系统130的结构示意图。通过比较图2和3可知，该第三换热器系统130与第二换热器系统120的不同之处在于中间集流管30内的腔体的分隔方式和第一和第二连通部件的设置方式不同，其余部分均与第二换热器系统120相同。
在本示例中，第一连通部件51和第二连通部件52设置成多根扁管的形式，在图3的下部的视图是示出了主隔板60上的用于容纳扁管的扁管孔的俯视图。
中间集流管30通过沿其纵向方向延伸的主隔板60分隔成上下两个腔体，即第一腔体31和第二腔体32；在主隔板60上与第一和第二连通部件51和52的多根扁管相对应的位置处设置有第一开口71和第二开口72(在本实例中，具体是多个扁管孔)。第一和第二连通部件51、52的每一扁管的一端插入穿过每个对应的扁管孔71、72进入了第一腔体31或第二腔体32中，以形成用于制冷剂的回路。可以理解，用作第一和第二连通部件51、52的扁管的数量可以根据需要进行设置，而不仅限于图示的数量。优选地，为了减小压降，通常将用于连通的扁管设置成较大或较多内部流通通道的扁管，这可能会需要较大尺寸(较宽、较高)的扁管，所以和扁管配合的连接件需要根据选用的扁管的尺寸而变化。因此可以将第一开口71和/或第二开 口72即用于连接所述用于连通的扁管的扁管孔设置成较大或者宽度或高度方向较大。
在第三换热器系统130的制冷剂的循环过程中，所述上部集流管10中的制冷剂从第一换热管41向下流动到所述第一腔体31中，之后经过第一连通部件51中的扁管流入到下部集流管30的腔体中，此后所述制冷剂从第二换热管42向上流入到所述第二腔体32中，进而经由第二连通部件52的扁管返回流入到上部集流管10中。
参见图4，示出了根据本发明的第一实施例的第四换热器系统140的结构示意图。通过比较图3和图4可知，该第四换热器系统140与第三换热器系统130的不同之处仅在于第一连通部件51和第二连通部件52选择成了等当量直径的圆管来替代扁管。这样做，可以在有限的安装空间内尽可能地增大单排换热器的换热面积。这样，在主隔板60上形成至少一个用于容纳圆管的第一开口71和第二开口72，具体是圆管孔71、72。
鉴于第四换热器系统140和第三换热器130的结构布置和工作原理相同，故在此不再详细说明。
参见图5，示出了根据本发明的第一实施例的第五换热器系统150的结构示意图。通过比较图1和图5可知，该第五换热器系统150与第一换热器110的不同之处在于，第一连通部件51和第二连通部件52为设置在对应的集流管的腔体外面的接管，并且通过沿中间集流管30的纵向方向设置的主隔板60被分隔成上下两个腔体，即第一腔体31和第二腔体32。
具体地，第一连通部件51和第二连通部件52分别设置成等当量直径的第一接管和第二接管，主隔板上不用进行任何加工，例如加工出开口、设置有副挡板等。第一接管51的两端通过相应的开孔分别插入到第一腔体31和下部集流管20的腔体中，而第二接管52的两端通过相应的开孔分别插入到第二腔体32和上部集流管10的腔体中。
在第五换热器系统的制冷剂的循环过程中，所述上部集流管10中的制冷剂从第一换热管41向下流动到所述第一腔体31中，之后经过第一接管51流入到下部集流管30的腔体中，此后所述制冷剂从第二换热管42向上流入到所述第二腔体32中，进而经由第二接管52返回流入到上部集流管10中。
参见图6，示出了根据本发明的第一实施例的第六换热器系统160的结构示意图。通过比较图6和图5可知，该第六换热器系统160与第五换热器系统150的区别仅在于在下部集流管20的腔体中还设置有分配来自第一接管51的流体的分液结构 80。所述分液结构80可以为与第一接管51连接或一体形成的导流管，所述导流管上设置有间隔分布的开口。
对于具有较长的集流管的换热器来说，在用作蒸发器的一侧的集流管中增设分液结构，可以有效地利用换热面积。
参见图7，示出了根据本发明的第一实施例的第七换热器系统170的结构示意图。通过比较图2和图7可知，该第七换热器系统170与第二换热器系统120的区别在于设置了更多数量的副挡板。通过设置更多的副挡板，可以调整第一换热器和第二换热器中的第一换热管和第二换热管的相对位置，使得它们不一定完全是严格的左右布置(如图1-6中所示的)。这样做可以根据换热器表面风场的分布，将主要起换热作用的第一和第二换热管布置在风速最高的地方，增大换热量。
具体地，通过从中间集流管30的左端沿中间集流管30的纵向方向延伸至所述中间集流管30的右端的主隔板621以及设置在主隔板621和中间集流管的上壁之间的两个副挡板622、在主隔板621与中间集流管的下壁之间的两个副挡板623将中间集流管30的腔体分隔成两个第一腔体31、一个第二腔体32和三个流通腔33和34。
在此，需要说明的是，副挡板622、623的设置方式可以是从中间集流管的上部或下部倾斜地、竖直地、弯曲地或蜿蜒地延伸至主隔板621，只要能够分隔出第一腔体和第二腔体即可。本发明对此不做限制。
在本示例中，第一腔体31和第二腔体32分别通过对应地设置在主隔板621上的第一开口71和第二开口72与相对应的连通腔33、34连通。
在第七换热器系统的制冷剂的循环过程中，所述上部集流管10中的制冷剂从位于左右两侧的第一换热管41分别向下流动到相对应的第一腔体31中，之后经过第一开口71流入到对应的流通腔33中。流通腔33中的制冷剂经由两个第一连通部件51分别流入到下部集流管30的腔体中，此后所述制冷剂从第二换热管42向上流入到所述第二腔体32中，该第二腔体32中的制冷剂经过第二开口72流入到流通腔34中，进而经由第二连通部件52返回流入到上部集流管10中。
也就是说，可以通过设置副挡板、在主隔板上设置开口等方式根据需要使得在第一和第二换热器之间形成多个制冷剂循环回路。虽然在图1-7中图示的第一至第7换热器系统中，大部分换热器系统仅图示出具有一个制冷剂循环回路，但是本领域技术人员可以根据需要重复这样的结构布置或以替代的方式改变换热器内的结构布置来实现具有多个制冷剂回路的目的。这样的替代或变形都将落入到本发明的保护范围内。
参见图8，示出了根据本发明的第二实施例的换热器系统200。该换热器系统200包括从上到下依次布置的上部集流管210、第一中间集流管230、第二中间集流管240和下部集流管220，上部集流管210与第一中间集流管230之间设置有第一换热管241并且第二中间集流管240和下部集流管220之间设置有第二换热管242。
所述第一中间集流管230设置有将所述第一中间集流管230分隔成相互独立的至少一个第一腔体231和至少一个第一连通腔234的第一隔板261。所述第二中间集流管240设置有将所述第二中间集流管240分隔成相互独立的至少一个第二腔体232和至少一个第二连通腔233的第二隔板262。
在制冷剂循环过程中，所述上部集流管210中的制冷剂从第一换热管241向下流动到第一腔体231中，经由第一连接管281进入到第二连通腔233内并通过第一连通部件251流入到下部集流管220的腔体中，此后所述制冷剂从第二换热管242向上流入到第二腔体232中，经由第二连接管282进入到第一连通腔234中，进而经由第二连通部件252返回流入到上部集流管210中。
如图8所示，第一中间集流管230通过设置的第一隔板261分隔成第一腔体231和第一连通腔234；第二中间集流管240通过设置的第二隔板262分隔成第二腔体232和第二连通腔233。显然，本领域技术人员可以根据需要分别在第一和第二中间集流管230、240内设置多个隔板261、262以形成多个制冷剂循环回路。在此不再显示和详细描述如何设置成多个制冷剂回路，本领域技术人员可以根据需要设置。
此外，本领域技术人员可以根据需要在第一和第二中间集流管230、240上合适的位置处设置开口以连接第一连接管281和第二连接管282，而不限于图8所显示的在第一中间集流管230的下部设置两个开口和在第二中间集流管240的上部设置两个相对应的开口。
在此，需要说明的，第一连通部件251和第二连通部件252可以是起连通作用的连通管或接管。优选地，如图8所示，所述第一连通部件251是设置在下部集流管220和第二中间集流管230之间的至少一个圆管或扁管，并且所述圆管或扁管与第二换热管242排列成一排设置在下部集流管220和第二中间集流管240之间。所述第二连通部件252是设置在上部集流管210和第一中间集流管230之间的至少一个圆管或扁管，并且所述圆管或扁管与第一换热管241排列成一排设置在上部集流管210和第一中间集流管230之间。
所述上部集流管210和第一中间集流管230以及它们之间的第一换热管241构成第一换热器，所述第二中间集流管240和下部集流管220以及它们之间的第二换热 管242构成第二换热器。在本发明中，为了说明的目的，将第一换热器称为冷凝器，而将第二换热器称为蒸发器。当然，本领域技术人员可以根据需要将第一和第二换热器设置成冷凝器、蒸发器或其他类型的换热器，本发明对此不做任何限制。
第一换热管241和第二换热管242可以是任何类型的换热管。通常，第一换热管241和第二换热管242被选择成圆管和扁管中的任一种。在同一换热器系统中，第一换热管241和第二换热管242不必设置成同一种类型的换热管，例如不必都是圆管或扁管，可以是其中的一种是圆管，而另一种是扁管，也可以是第一和第二换热管241、242中的一部分是圆管，而另一部分是扁管。也就是说，本文所述的第一和第二换热管241、242可以根据需要设置成任何类型的可行的换热管，本发明对此不做任何特殊限制。
另外，相邻的两根第一换热管241或相邻的两根第二换热管242之间可以是设置有翅片，而不必考虑换热管的类型。
可以理解，如果将第一换热管241和第二连通部件252例如都设置成是圆管和/或扁管；那么可以将第一换热管241和第二连通部件252排列成一排设置在上部集流管210和第一中间集流管230之间，如图8所示。同理，如果将第二换热管242和第一连通部件251例如都设置成是圆管和/或扁管；那么可以将第二换热管242和第一连通部件251排列成一排设置在下部集流管220和第二中间集流管240之间，如图8所示。这样做可以简化第一换热器和/或第二换热器的制造工艺和制造难度，并且能够减少第一换热器和/或第二换热器的厚度。
如图8所示，在第一换热器中，多根第一换热管241设置在第一换热器的左侧，而第二连通部件252设置在第一换热器的右侧。另外，在第二换热器中，多根第二换热管242设置在第二换热器的右侧，而第一连通部件251设置在第二换热器的左侧。可以理解，本领域技术人员可以根据需要设置第一换热管241和第二连通部件252的相对位置，而不必限制成如图所示的那样，例如可以将第一换热管241设置成位于中间，第二连通部件252位于其的两侧。这也适用于第二换热管242和第一连通部件251，在此不再详述。
通过设置第一隔板261和第二隔板262将第一和第二中间集流管230、240分割成彼此独立的第一腔体231、第二腔体232以及相应的连通腔233、234。可以理解，第一和第二隔板261、262的形状可以设置成任何适当的形式，只要保证分隔出第一腔体231和第二腔体232即可，不限于图8所述的形式。例如第一和第二隔板261、262可以设置成从第一中间集流管230或第二中间集流管240的上壁倾斜地、竖直 地、弯曲地或蜿蜒地延伸至其的下壁。
另外，需要说明的是，图8仅示出了一个制冷剂循环。当然，还可以将所述换热器系统设置成具有多个制冷剂循环，即在增加上部集流管210、第一中间集流管230、第二中间集流管240和下部集流管220的纵向长度的情况下，在图8所示的结构布置的两侧根据需要设置重复的结构单元，以实现上述的目的。
在第一换热器为冷凝器且第二换热器为蒸发器的情况下，以扁管作为换热管为例作为本发明的图8所示的换热器系统的在制冷时的工作原理。具体地，冷凝器中的制冷剂气体放热后，变为液体制冷剂，因重力的影响从放热扁管(第一换热管241)流下；在流入到蒸发器中之后在蒸发器内吸收热量，变为气体制冷剂，从吸热扁管(第二换热管242)流上去，并最终流入到冷凝器中；如此循环，达到了制冷的作用。
参见图9，示出了根据本发明的第三实施例的换热器系统300。该换热器300包括上部集流管310、中间集流管330和下部集流管320。上部集流管310与中间集流管330之间设置有第一换热管341并且中间集流管330和下部集流管320之间设置有第二换热管342。
所述上部集流管310和中间集流管330以及它们之间的第一换热管341构成第一换热器，优选地为冷凝器，所述中间集流管330和下部集流管320以及它们之间的第二换热管342构成第二换热器，优选地为蒸发器。
根据本发明的第三实施例的换热器系统300可以具有根据本发明的第一实施例所述的第一至第七换热器系统相类似的结构，但是其不同之处在于：所述第一换热器或第二换热器中的一部分被折弯，以便于能够安装在更加紧凑的空间中。或者说，在根据本发明的第三实施例的换热器系统中上部集流管310、中间集流管330和下部集流管320不是从上到下依次设置的(或者它们大体处于同一竖直平面中)，而是相互之间成一定的角度。具体的相互之间的角度可以根据需要进行设置。例如图9所示的，上部集流管310可以与中间集流管330设置成45°的角度，而中间集流管330和下部集流管320设置成大体处于同一水平面中。
具体地，可以将第一换热器或第二换热器中的第一换热管341或第二换热管342被折弯，以实现折弯换热器的目的。
另外，还可以将第一换热管341和第二换热管342相对彼此倾斜地插入到中间集流管330中(例如在中间集流管330上的安装孔设置成不是彼此直接对准，而不是相互之间成一定的角度)而实现折弯换热器的目的。
当然，上述的使得第一换热器和第二换热器倾斜设置的构思也适用于根据本发明第二实施例所述的换热器系统。例如，可以将第一换热器或第二换热器中的第一换热管241或第二换热管242折弯，以使得实现折弯换热器的目的。
另外，还可以将第一换热管241和第二换热管242相对彼此倾斜地插入到相应的第一和第二中间集流管中(例如在第一中间集流管和第二中间集流管上的安装孔设置成不是彼此直接对准，而是相互之间成一定的角度)，从而可以使得第一换热器和第二换热器相对彼此倾斜地布置。
在第三实施例中，通过将第一换热器和/或第二换热器折弯或相对彼此倾斜地设置，可以使得对于某些有安装空间要求的系统，更加方便风机、风道的安装布置。
需要说明的是，在本发明的第一至第三实施例所示出的各种换热器系统中，都是以单排换热器为例如说明了如何设置蒸发器、冷凝器，但是本领域技术人员可以将蒸发器和/或冷凝器设置成多排换热器，本发明对此不做限制。另外，虽然在本发明的第一至第三实施例所示出的各种换热器系统中，所述换热器系统可以仅包括彼此连通的冷凝器和蒸发器即可实现制冷剂循环的目的，但是为了增加制冷剂的循环效率，还可以在该制冷剂的循环路径中增设压缩机。
另外，可以理解，在本发明的第一至第三实施例中，第一连通部件和第二连通部件可以相同或不同，以及第一连通部件与第一腔体的连通方式和第二连通部件与第二腔体的连通方式可以相同或不同。或者说，本领域技术人员可以根据本发明的图1-8中所示的方式根据需要选择或适当地组合第一连通部件、第二连通部件、第一连通部件与第一腔体的连通方式和第二连通部件与第二腔体的连通方式。
通过上述的可知，本发明的第一至第三实施例所述的换热器系统至少具有以下优点中的至少一个：
1、加工可行性高；
2、成本低；
3、系统安全失效风险较小；
4、需要的安装空间小；
5、对于集流管较长的蒸发器，可以更加分液结构，有效地利用换热面积；
6、可以根据风场的分布灵活地布置换热管，增加换热量；
7、折弯蒸发器和/或冷凝器；或者倾斜地布置蒸发器和冷凝器，可以更加方便地布置风机和风道，适应不同的安装需求。
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。
