Description

换热器及其集流管组件 技术领域
本发明涉及换热技术领域，具体地，涉及一种用于换热器的集流管组件，还涉及具有所述集流管组件的换热器。
背景技术
在相关技术中，在将换热器(尤其是多通道全铝换热器)的连接管(进口连接管或出口连接管)与换热器的集流管连接时，是将连接管与集流管直接焊接，或者连接管与转接管焊接，转接管再与集流管焊接。然而，在焊接过程中，存在焊料难以均匀地填充在连接管与转接管之间、连接管与集流管之间或转接管与集流管之间，焊缝中普遍出现气孔现象(即焊缝中具有气孔)，极大地降低了整个焊接结构的可靠性。
发明内容
本发明是基于发明人对以下事实和问题的认识作出的。
现有的换热器在组装时，如果连接管通过转接管安装在集流管上，则在集流管与转接管之间放置焊料件(例如焊料环)且在连接管与转接管之间放置焊料件，如果连接管直接安装在集流管上，则在集流管与连接管之间放置焊料件。然后，采用NB炉钎焊方式将上述部件焊接在一起。但是，焊料难以均匀地填充在转接管与集流管之间、连接管与转接管之间、连接管与集流管之间，焊缝中普遍出现气孔现象(即焊缝中具有气孔)，极大地降低了整个焊接结构的可靠性。
经过发明人深入地研究后，发现了产生上述问题的原因：由于在进行NB炉钎焊时，连接管、转接管和集流管的转接块水平放置，因此不仅导致该转接块与转接管之间的间隙不均匀、转接管与连接管之间的间隙不均匀、该转接块与连接管之间的间隙不均匀，而且导致转接管、连接管产生径向位移和轴向位移，最终导致焊料难以均匀地填充在转接管与集流管之间、转接管与连接管之间、连接管与集流管之间以及焊缝中具有气孔。
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本发明的一个目的在于提出一种具有焊接牢固、密封性能好、结构稳定、使用寿命长的优点的用于换热器的集流管组件。

由此在焊接集流管100和转接管200以及焊接转接管200和连接管300时，该导流部不仅可以对融化的焊剂产生毛细效应，促进钎剂进一步流动，使钎剂可以很好地漫流在整个焊接面上，并使钎剂填充在转接管200的第一端210与集流管100的整个焊接面(接触面)以及转接管200的第二端220与连接管300的整个焊接面(接触面)，以便获得较好的钎剂填充率，增大焊接的连接面积(焊合面积)，而且可以提供空气排出的通道，以便排除钎剂中的空气，减少气孔，加强焊接强度，提高焊接质量以及后续的使用寿命和抗腐蚀能力。
而且，可以取消焊环的使用，避免了由于焊环放置或者固定等问题造成的焊接不良，提高了焊接质量控制。其中，转接管200和集流管100的焊接质量以及转接管200和连接管300的焊接质量可以通过肉眼直接地从外观看出，有助于控制产品的质量。
因此，根据本发明实施例的用于换热器10的集流管组件1具有焊接质量好、焊接强度高、使用寿命长、抗腐蚀能力强等优点。
如图1-图22所示，根据本发明实施例的用于换热器10的集流管组件1包括集流管100、转接管200和连接管300。其中，连接管300为不锈钢管。连接管300的第一端310具有圆形横截面，连接管300的第二端320连接有铜管600。
为了进一步保证连接管300与转接管200的焊接强度以及转接管200与集流管100的 焊接强度，连接管300的第一端310过盈配合或过渡配合在转接管200的第二端220内，转接管200的第一端210过盈配合或过渡配合在插孔110内。由此可以提高连接管300与转接管200的连接紧密性以及转接管200与集流管100的连接紧密性。
有利地，该导流部为导流槽400和导流孔600中的至少一个。
连接管300的第一端310与转接管200的第二端220套设。也就是说，在本发明的一个示例中，连接管300的第一端310设在转接管200的第二端220内，即转接管200的第二端220套装在连接管300的第一端310上。在本发明的另一个示例中，转接管200的第二端220设在连接管300的第一端310内，即连接管300的第一端310套装在转接管200的第二端220上。
连接管300的第一端310的壁面和/或转接管200的第二端220的壁面上设有导流孔600。也就是说，连接管300的第一端310的壁面上设有导流孔600且转接管200的第二端220的壁面上不设置导流孔600，或者转接管200的第二端220的壁面上设有导流孔600且连接管300的第一端310的壁面上不设置导流孔600，或者连接管300的第一端310的壁面上设有导流孔600且转接管200的第二端220的壁面上设有导流孔600。
如图3-图5所示，连接管300的第一端310配合在转接管200的第二端220内，连接管300的第一端310的壁面上设有导流孔600。导流孔600为通孔(如图3所示)或凹口(如图4所示)。由此可以将转接管200和连接管300更加牢固地焊接在一起。其中，该凹口可以是半圆形、柜形、三角形、梯形或锯齿形等。
有利地，连接管300的第一端310的壁面上设有多个导流孔600和/或转接管200的第二端220的壁面上设有多个导流孔600。其中，多个导流孔600中的每一个均为通孔或凹口，或者多个导流孔600中的一部分为通孔且多个导流孔600中的其余部分为凹口。
多个导流孔600可以在转接管200的周向上和/或连接管300的周向上均匀地分布，多个导流孔600也可以在转接管200的周向上和/或连接管300的周向上上下交叉分布。
其中，导流孔600的总面积与连接管300和转接管200相互配合的部分的周面面积的比值小于70％。换言之，导流孔600的总面积与连接管300配合在转接管200内的部分的外周面积的比值小于70％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而可以获得更好的钎剂填充率，进而可以进一步提高焊接强度。
有利地，导流孔600的总面积与连接管300配合在转接管200内的部分的外周面积的比值在3％-50％的范围内。换言之，导流孔600的总面积与连接管300配合在转接管200内的部分的外周面积的比值大于等于3％且小于等于50％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而获得更好的钎剂填充率，进而可以进一步提高焊接强度。
如图6所示，连接管300的第一端310的壁面上设有导流孔600，且转接管200的第二 端220的壁面上设有导流孔600。有利地，当转接管200的第二端220和连接管300的第一端310均形成有导流孔600时，转接管200的第二端220配合在连接管300的第一端310内。
在本发明的一个实施例中，形成在转接管200的第二端220的壁面上的导流孔600与形成在连接管300的第一端310的壁面上的导流孔600在转接管200的径向上对齐。由此不仅可以进一步促进钎剂流动，而且可以更多地排除钎剂中的空气，进一步减少气孔。
有利地，转接管200的热膨胀系数大于连接管300的热膨胀系数。由此可以将转接管200和连接管300更加牢固地焊接在一起，提高该接口管转接组件的焊接强度。
如图6所示，转接管200配合在连接管300内的第二端220的外径小于转接管200的其余部分的外径。由此转接管200上可以形成台阶部，转接管200的第二端220配合在连接管300内时，连接管300可以抵靠在该台阶部上。
如图6所示，转接管200的第二端220的壁面上设有导流孔600，连接管300的第一端310的壁面上也设有导流孔600。通过在转接管200上形成台阶部且使连接管300抵靠在该台阶部上，从而可以使形成在转接管200的第二端220的壁面上的导流孔600与形成在连接管300的第一端310的壁面上的导流孔600更加容易地、精确地在转接管200的径向上对齐。
在本发明的一个示例中，如图2所示，转接管200的第二端面上设有插槽，连接管300的第一端310插入配合在该插槽内，导流孔600至少形成在转接管200的第二端220上，且导流孔600与该插槽连通。通过在转接管200的第二端面上设有插槽，从而可以使转接管200和连接管300更加方便地、容易地配合在一起。
转接管200的第一端210的外壁面和插孔110的壁面中的至少一个上设有导流孔600。如图7和图8所示，导流孔600还形成在转接管200的第一端210。换言之，转接管200的第一端210上设有导流孔600。由此可以将集流管100和转接管200更加牢固地焊接在一起。
如图7所示，转接管200的第一端210的外壁上设有台阶，该台阶抵靠到集流管100的外壁面上。由此可以使集流管组件1和换热器10的结构更加合理。
有利地，导流孔600的总面积与转接管200配合在插孔110内的部分的外周面积的比值小于70％。换言之，导流孔600的总面积与转接管200和插孔110相互配合的部分的周面面积的比值小于70％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而可以获得更好的钎剂填充率，进而可以进一步提高焊接强度。
更加有利地，导流孔600的总面积与转接管200配合在插孔110内的部分的外周面积的比值在3％-50％的范围内。换言之，导流孔600的总面积与转接管200配合在插孔110内 的部分的外周面积的比值大于等于3％且小于等于50％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而获得更好的钎剂填充率，进而可以进一步提高焊接强度。
如图9和图10所示，转接管200的第一端210的外壁面和插孔110的壁面上均设有导流槽400。由此可以使融化的焊剂流入转接管200的第一端210和插孔110上的导流槽400，从而增大转接管200的第一端210与插孔110的焊合面积，进而提高转接管200和集流管100的焊接强度。
进一步地，连接管300的第一端310的外壁面和转接管200的第二端220的内壁面上均设有导流槽400。由此可以使融化的焊剂流入连接管300的第一端310和转接管200的第二端220上的导流槽400，从而增大连接管300的第一端310与转接管200的第二端220的焊合面积，进而提高连接管300和转接管200的焊接强度。
可选地，导流槽400为直线槽、螺旋槽或通过滚花形成的槽。
举例而言，导流槽400可以为分别设在插孔110的壁面、转接管200的第一端210的外壁面、转接管200的第二端220的内壁面和连接管300的第一端310的外壁面上的螺旋槽(如图9所示)。
导流槽400可以为分别设在插孔110的壁面、转接管200的第一端210的外壁面和连接管300的第一端310的外壁面上的直线槽(如图10所示)。
本领域的技术人员需要理解地是，本发明对导流槽400在转接管200的第一端210和第二端220的壁面、插孔110的壁面和连接管300的第一端310的壁面上的具体位置以及导流槽400的形状和个数不做具体限定，只要在连接管300、转接管200和集流管100三者之间的焊接面上形成缝隙即可。
如图13、图14、图19-图22所示，插孔110的至少一部分的横截面为第一形状，转接管200的第一端210的横截面为第二形状，转接管200的第二端220的横截面为第三形状，连接管300的第一端310的横截面为第四形状。
其中，该第二形状和该第四形状中的至少一个不同于该第一形状和该第三形状中的相应的至少一个，插孔110的至少一部分与转接管200的第一端210以及连接管300的第一端310与转接管200的第二端220中的至少一对之间形成用于对焊剂产生毛细力且被焊剂填充的导流空隙。该导流空隙为该导流部。
具体而言，该第二形状不同于该第一形状以便在插孔110的至少一部分与转接管200的第一端210之间形成该导流空隙，或者该第四形状不同于该第三形状以便在连接管300的第一端310与转接管200的第二端220之间形成该导流空隙，或者该第二形状不同于该第一形状以便在插孔110的至少一部分与转接管200的第一端210之间形成该导流空隙且该第四形状不同于该第三形状以便在连接管300的第一端310与转接管200的第二端220 之间形成该导流空隙。
有利地，该第二形状和该第四形状中的至少一个为非圆形且该第一形状和该第三形状中的相应的至少一个为圆形，或者该第二形状和该第四形状中的至少一个为圆形且该第一形状和该第三形状中的相应的至少一个为非圆形。
如图13所示，该第一形状为非圆形，该第二形状为圆形，该第三形状为非圆形，该第四形状为圆形。有利地，该非圆形为正多边形。更加有利地，该多边形的边数大于等于5个。
如图13、图14、图19和图20所示，转接管200的第二端220具有正多边形孔，这样不仅可以方便转接管200的加工，且转接管200的第二端220的该正多边形孔的相邻两个内壁面之间可以与连接管300的第一端310的外周面之间形成该导流空隙，以将融化的焊剂吸入其中。
如图13和图14所示，插孔110与转接管200的第一端210中的一个具有非圆形横截面，且插孔110与转接管200的第一端210中的另一个具有圆形截面。图13和图14中示出了插孔110具有非圆形横截面且转接管200的第一端210具有圆形横截面的示例。当然，也可以将插孔110构造成具有圆形横截面且将转接管200的第一端210构造成具有非圆形横截面。这样转接管200的第一端210配合在插孔110内时，转接管200的第一端210与插孔110之间形成焊剂导流缝，焊接时融化的焊剂可以流入该导流空隙中，从而增大转接管200的第一端210和插孔110的焊合面积，进而提高转接管200和集流管100的焊接强度。
具体地，转接管200的第一端210和插孔110中的一个具有圆形横截面，转接管200的第一端210和插孔110中的另一个具有正多边形横截面。
举例而言，插孔110具有圆形横截面，转接管200的第一端210具有非圆形横截面，且转接管200的第一端210上设有插入集流管100内的圆柱段(图中未示出)，该圆柱段具有圆形横截面。换言之，转接管200的第一端210的配合在插孔110内的部分具有非圆形横截面，转接管200的第一端210的插入集流管100内的部分具有圆形横截面。
在本发明的另一些具体示例中，转接管200的第一端210和插孔110也可以均具有多边形横截面，即转接管200的第一端210和插孔110多边形配合。
如图14、图19-图22所示，连接管300的第一端310的外壁面、转接管200的第二端220的内壁面、转接管200的第一端210的外壁面和插孔110的壁面中的至少一个上设有导流槽400和导流孔600中的至少一个。
换言之，连接管300、转接管200和集流管100三者之间的焊接面中的至少一个上设有导流槽400和导流孔600中的至少一个。焊接时，融化的焊接不仅可以通过焊接面之间的 该导流空隙流入两个焊接部件之间，而且可以通过导流槽400和导流孔600中的至少一个进一步流入，由此可以进一步提高焊接强度。
可选地，导流槽400为直线槽、螺旋槽或通过滚花形成的槽。
举例而言，导流槽400可以为分别设在连接管300的第一端310的外壁面、转接管200的第二端220的内壁面、转接管200的第一端210的外壁面和插孔110的内壁面上的直线槽(如图14所示)。导流槽400可以为设在转接管200的第一端210的外壁面上的螺旋槽(如图19所示)。导流槽400可以为通过转接管200的第一端210的外壁面上的滚花形成的槽(如图20所示)。导流槽400可以为设在插孔110的内壁面上的螺旋槽(如图21所示)。导流槽400可以为设在插孔110的内壁面上的直线槽(如图22所示)。
本领域的技术人员需要理解地是，本发明对导流槽400在连接管300的第一端310的外壁面、转接管200的第二端220的内壁面、转接管200的第一端210的外壁面和插孔110的壁面上的具体位置以及导流槽400的形状和个数不做具体限定，只要在连接管300、转接管200和集流管100三者之间的焊接面上形成缝隙即可。
如图8所示，根据本发明的另一个实施例用于换热器10的集流管组件1包括集流管100和连接管300。集流管100的壁面上设有插孔110。连接管300具有第一端310和第二端320，连接管300的第一端310配合在插孔110内，连接管300的第一端310与集流管100焊接。其中，插孔110的壁面和连接管300的第一端310的外壁面中的至少一个上设有用于对焊剂产生毛细力的导流部。
也就是说，在该实施例中，集流管组件1不包括转接管200，而是将连接管300直接焊接在集流管100上。
根据本发明实施例的用于换热器10的集流管组件1通过在插孔110的壁面和连接管300的第一端310的外壁面中的至少一个上设有用于对焊剂产生毛细力的导流部，从而可以在插孔110的壁面与连接管300的第一端310的壁面之间形成缝隙。
由此在焊接集流管100和连接管300时，该导流部不仅可以对融化的焊剂产生毛细效应，促进钎剂进一步流动，使钎剂可以很好地漫流在整个焊接面上，并使钎剂填充在连接管300的第一端210与集流管100的整个焊接面(接触面)，以便获得较好的钎剂填充率，增大焊接的连接面积(焊合面积)，而且可以提供空气排出的通道，以便排除钎剂中的空气，减少气孔，加强焊接强度，提高焊接质量以及后续的使用寿命和抗腐蚀能力。
而且，可以取消焊环的使用，避免了由于焊环放置或者固定等问题造成的焊接不良，提高了焊接质量控制。其中，连接管300和集流管100的焊接质量可以通过肉眼直接地从外观看出，有助于控制产品的质量。
因此，根据本发明实施例的用于换热器10的集流管组件1具有焊接质量好、焊接强度 高、使用寿命长、抗腐蚀能力强等优点。
有利地，该导流部为导流槽400和导流孔600中的至少一个。
如图8所示，集流管100的壁面上设有圆形的插孔110，连接管300为圆管且具有第一端310和第二端320，连接管300的第一端310配合在圆形的插孔110内且与集流管100焊接，连接管300的第一端的外壁面上设有导流孔600。
导流孔600为通孔或凹口。其中，该凹口可以是半圆形、柜形、三角形、梯形或锯齿形等。
有利地，连接管300的第一端310的壁面上设有多个导流孔600和/或插孔110的壁面上设有多个导流孔600。其中，多个导流孔600中的每一个均为通孔或凹口，或者多个导流孔600中的一部分为通孔且多个导流孔600中的其余部分为凹口。
多个导流孔600可以在连接管300的周向上和/或插孔110的周向上均匀地分布，多个导流孔600也可以在连接管300的周向上和/或插孔110的周向上上下交叉分布。
其中，连接管300的第一端310的外壁面和插孔110的壁面中的至少一个上设有导流孔600，导流孔600的总面积与连接管300的第一端310的配合在插孔110内的部分的外壁面的面积的比值小于70％。换言之，导流孔600的总面积与连接管300的第一端310和插孔110相互配合的部分的周面面积的比值小于70％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而可以获得更好的钎剂填充率，进而可以进一步提高焊接强度。
有利地，导流孔600的总面积与连接管300的第一端310的配合在插孔110内的部分的外壁面的面积的比值在3％-50％的范围内。换言之，导流孔600的总面积与连接管300的第一端310的配合在插孔110内的部分的外壁面的面积的比值大于等于3％且小于等于50％。由此可以进一步确保钎剂在毛细效应下漫流在整个焊接面上，从而获得更好的钎剂填充率，进而可以进一步提高焊接强度。
在本发明的一个实施例中，形成在连接管300的第一端310的壁面上的导流孔600与形成在插孔110的壁面上的导流孔600在连接管300的径向上对齐。由此不仅可以进一步促进钎剂流动，而且可以更多地排除钎剂中的空气，进一步减少气孔。
如图11所示，连接管300的第一端310的外壁面上设有导流槽400，插孔110的壁面上没有设置导流槽400。如图12所示，连接管300的第一端310的外壁面上设有导流槽400，插孔110的壁面上也设置导流槽400。
由此可以使融化的焊剂流入连接管300的第一端310和插孔110上的导流槽400，从而增大连接管300的第一端310与插孔110的焊合面积，进而提高连接管300和集流管100的焊接强度。
可选地，导流槽400为直线槽、螺旋槽或通过滚花形成的槽。
本领域的技术人员需要理解地是，本发明对导流槽400在连接管300的第一端310的外壁面和插孔110的壁面上的具体位置以及导流槽400的形状和个数不做具体限定，只要在连接管300和集流管100二者之间的焊接面上形成缝隙即可。
如图15-图18所示，插孔110的至少一部分的横截面为第一形状，连接管300的第一端310的横截面为第二形状。其中，该第二形状不同于该第一形状。由此，插孔110的至少一部分与连接管300的第一端310之间形成用于对焊剂产生毛细力且被焊剂填充的导流空隙。该导流空隙为该导流部。
有利地，该第二形状为非圆形且该第一形状为圆形，或者该第二形状为圆形且该第一形状为非圆形。
如图15-图17所示，该第一形状为非圆形，该第二形状为圆形。如图18所示，该第二形状为非圆形，该第一形状为圆形。有利地，该非圆形为正多边形。更加有利地，该多边形的边数大于等于5个。
具体地，插孔110具有圆形横截面，连接管300的第一端310具有非圆形横截面，且连接管300的第一端310上设有插入集流管100内的圆柱段(图中未示出)，该圆柱段具有圆形横截面。换言之，连接管300的第一端310的配合在插孔110内的部分具有非圆形横截面，连接管300的第一端310的插入集流管100内的部分具有圆形横截面。
如图18所示，连接管300的第一端310的外壁面和插孔110的壁面中的至少一个上设有导流槽400和导流孔600中的至少一个。
换言之，连接管300和集流管100二者之间的焊接面中的至少一个上设有导流槽400和导流孔600中的至少一个。焊接时，融化的焊接不仅可以通过焊接面之间的该导流空隙流入两个焊接部件之间，而且可以通过导流槽400和导流孔600中的至少一个进一步流入，由此可以进一步提高焊接强度。
本领域的技术人员需要理解地是，本发明对导流槽400在连接管300的第一端310的外壁面和插孔110的壁面上的具体位置以及导流槽400的形状和个数不做具体限定，只要在连接管300和集流管100二者之间的焊接面上形成缝隙即可。
