具体实施方式
下面结合附图及具体实施方式对本发明做进一步说明。
参见图1至37，根据本发明的实施例的无翅片换热器100包括：换热管1，所述换热管1包括主体；和形成在所述主体中的流体通道11；以及与换热管1连接的集流管2。
参见图4至5，在本发明的实施例中，在横截面中观看时，所述换热管1的主体具有至少两个直线状的主体部分10。例如，如图4所示，在横截面中观看时，所述换热管1的主体包括三个直线状的主体部分10，三个直线状的主体部分10中的第一主体部分10沿第一方向延伸，三个直线状的主体部分中的第二主体部分10从第一主体部分的端部沿相对于第一方向倾斜的第二方向延伸，三个直线状的主体部分10中的第三主体部分10从第二主体部分10的远离第一主体部分的端部沿与第一方向大致平行的第三方向延伸。作为选择，第三方向可以相对于第一方向和第二方向倾斜。例如，如图5所示，在横截面中观看时，所述换热管1的主体包括四个直线状的主体部分10，且所述换热管1的主体为倒W状。
参见图3，在本发明的实施例中，所述换热管1还包括形成在所述主体的相对的表面中的至少一个上的突起12。所述突起12可以沿所述换热管1的纵向方向连续延伸。突起12可以是肋部。
由于换热管1具有突起13，设置成阶梯状和倒W状，因此在空气通过换热管1时形成紊流，由此改善换热性能，同时，也提高了换热管1的抗弯强度。
参见图6至9，在本发明的实施例中，所述无翅片换热器100还包括：换热管支架3，所述换热管支架3包括支架主体以及贯穿支架主体的通孔31，所述换热管1分别穿过所述换热管支架3的通孔31。在本发明的实施例中，所述换热管1包括第一排换热管1和第二排换热管1，所述集流管2包括第一集流管2和第二集流管2，第一排换热管1和第二排换热管1的第一端部与第一集流管2连接，第一排换热管1和第二排换热管1的第二端部与第二集流管2连接。第一集流管2和第二集流管2中的至少一个具有纵向隔板，纵向隔板将第一集流管2和第二集流管2中的至少一个的内腔分隔成两个腔室。所述换热管支架3可以是板状件。例如，板状件的厚度是大约1毫米。板状件可以在一侧或两侧具有覆层，以便能够与换热管焊接在一起。
参见图10至21，在本发明的实施例中，所述换热管1包括第一排换热管1和第二排换热管1，第一排换热管1和第二排换热管1在 换热管1的排列方向DA上相互错开。由此，通过第一排换热管1的空气将撞击第二排换热管1并分开，由此将破坏边界层并改善换热器的热性能。
参见图10至21，在本发明的实施例中，所述集流管2包括分别与第一排换热管1和第二排换热管1连接的第一集流管2和第二集流管2，第一集流管2的用于插入第一排换热管1的端部的开口的位置与第二集流管2的用于插入第二排换热管1的端部的开口的位置在第一排换热管1或第二排换热管1的排列方向DA上相互错开。
参见图10至21，在本发明的实施例中，第一集流管2和第二集流管2的在所述排列方向DA上的同一侧的端面21在所述排列方向DA上大致对齐，或第一集流管2与第二集流管2的在所述排列方向DA上的同一侧的端面21在所述排列方向DA上相距预定距离。
参见图10至12、16至18，在本发明的实施例中，第一集流管2是一对第一对集流管2，并且第二集流管2是一对第二对集流管2。
参见图13至15、19至21，在本发明的实施例中，第一集流管2和第二集流管2分别与换热管1的第一端部和第二端部连接，通过使换热管1在中部弯曲，构成第一排换热管1和第二排换热管1，且第一集流管2和第二集流管2位于换热器的同一侧。
参见图10至12，在本发明的实施例中，所述集流管2包括分别与第一排换热管1和第二排换热管1连接的第一对集流管2和第二对集流管2，第一对集流管2的用于插入第一排换热管1的端部的开口的位置与第二对集流管2的用于插入第二排换热管1的端部的开口的位置在第一排换热管1或第二排换热管1的排列方向DA上相互错开，且第一对集流管2和第二对集流管2的在所述排列方向DA上的同一侧的端面21在换热管1的排列方向DA上大致对齐。即，第一对集流管2和第二对集流管2的用于插入换热管1的端部的开口的位置在集流管的纵向方向上不同。位于换热器的一侧的第一集流管2和第二集流管2可以通过连接管连接。
参见图13至15，在本发明的实施例中，所述集流管2包括分别与换热管1的第一端部和第二端部连接的第一集流管2和第二集流管 2，通过使换热管1在中部弯曲，第一集流管2和第二集流管2位于换热器100的同一侧(图13中的左侧)，第一集流管2的用于插入换热管1的第一端部的开口的位置与第二集流管2的用于插入换热管1的第二端部的开口的位置在换热管1的排列方向DA上相互错开，且第一集流管2和第二集流管2的在所述排列方向DA上的同一侧的端面21在换热管1的排列方向DA上大致对齐。即，第一集流管2和第二集流管2的用于插入换热管1的端部的开口的位置在集流管的纵向方向上不同。需要说明的是“中部”并不限于换热管1的长度方向上的中心，而是指相对于换热管1长度方向上的两端而言的中间部分。
参见图16至18，在本发明的实施例中，所述集流管2包括分别与第一排换热管1和第二排换热管1连接的第一对集流管2和第二对集流管2，第一对集流管2的用于插入第一排换热管1的端部的开口的位置与第二对集流管2的用于插入第二排换热管1的端部的开口的位置在第一排换热管1或第二排换热管1的排列方向DA上相互错开，且第一对集流管2与第二对集流管2的在所述排列方向DA上的同一侧的端面21在第一排换热管1或第二排换热管1的排列方向DA上相距预定距离。即，第一对集流管2和第二对集流管2的用于插入换热管1的端部的开口的位置在集流管的纵向方向上相同，但是通过第一对集流管2和第二对集流管2在第一排换热管1或第二排换热管1的排列方向DA上相互偏移，使第一排换热管1和第二排换热管1错开。位于换热器的一侧的第一集流管2和第二集流管2通过连接管连接。
参见图19至21，在本发明的实施例中，所述集流管2包括分别与换热管1的第一端部和第二端部连接的第一集流管2和第二集流管2，通过使换热管1在中部弯曲，第一集流管2和第二集流管2位于换热器100的同一侧，第一集流管2的用于插入换热管1的第一端部的开口的位置与第二集流管2的用于插入换热管1的第二端部的开口的位置在换热管1的排列方向DA上相互错开，且第一集流管2和第二集流管2的在所述排列方向DA上的同一侧的端面21在换热管1 的排列方向DA上相距预定距离。即，第一集流管2和第二集流管2的用于插入换热管1的端部的开口的位置在集流管的纵向方向上相同，但是通过第一集流管2和第二集流管2在换热管1的排列方向DA上相互偏移，使通过弯曲换热管而形成的第一排换热管1和第二排换热管1错开。
根据本发明的实施例，参见图22和23，利用捆扎带4捆扎集流管2，将组装的换热器100捆扎在一起，以进行焊接。
参见图22，在本发明的实施例中，所述换热管1的两个端部具有相对于换热管1的纵向方向倾斜的端面13。所述换热管1的两个端部的倾斜的端面13可以彼此大致平行。由此，在形成换热管1时可以没有废料。由于两个端部的倾斜的端面使端部能够更深地插入集流管2中，而支撑集流管2的内壁，同时由于倾斜的端面也保证了不会由于端部更深地插入集流管2而增加换热管1出口处的流阻。倾斜的端面13可以从换热管1的第一边缘14延伸到所述换热管1的在宽度方向上与第一边缘14相对的第二边缘15。对于传统的有翅片的换热器，是利用捆扎带4沿着平行于集流管长度方向的方向捆扎换热管1，将组装的换热器100捆扎在一起，以进行焊接。本发明的实施例中，用捆扎带4捆扎集流管2，将组装的换热器100捆扎在一起，可以防止使用上述传统方法捆扎而导致的由于换热管1间没有翅片的支撑，换热管1受捆扎带4的压力而发生塌陷的问题。由于端部支撑在集流管2的内壁上，使得利用捆扎带4捆扎集流管2，将组装的换热器100捆扎在一起成为可能。
参见图23，在本发明的实施例中，所述换热管1的两个端部中的每一个具有从换热管1的第一边缘延14伸到所述换热管1的宽度方向上的中部且相对于换热管1的纵向方向倾斜的第一端面部分131；和从换热管1的在宽度方向上与第一边缘14相对的第二边缘15延伸到所述换热管1的宽度方向上的中部且相对于换热管1的纵向方向倾斜的第二端面部分132。在第一端面部分131和第二端面部分132之间形成尖部16，所述尖部16与集流管的内壁接触。需要说明的是此处的“中部”并不限定于是换热管1的宽度方向上的中心， 而是指相对于换热管1宽度方向上的两端而言的中间部分。由于端部的倾斜的端面使端部能够更深地插入集流管2中，而支撑集流管2的内壁，同时由于倾斜的端面也保证了不会由于端部更深地插入集流管2而增加换热管1出口处的流阻。由于端部支撑在集流管2的内壁上，可以利用捆扎带4捆扎集流管2，将组装的换热器100捆扎在一起。
在本发明的一些示例中，换热管1上设置有与集流管2外壁相接触的阻挡结构，例如凸起、换热管1端部进行缩口设置形成的肩部。
参见图24至29，在本发明的实施例中，集流管2具有用于插入换热管1的端部的开口，以及与该开口相对的支撑件插入口，所述换热器100还包括支撑件5，所述支撑件5从支撑件插入口插入集流管2，与从所述开口插入的换热管1的端部的端面邻接。所述支撑件5可以具有方头螺栓状的形状。所述支撑件5可以具有插入所述插入口的杆部51和与杆部51连接的位于集流管2外部的头部52，所述头部51覆盖所述插入口。由于所述支撑件5与插入集流管2的换热管1的端部的端面邻接，
参见图22和29，所述换热管1的端部支撑集流管2的内壁，所述换热管1的端面与集流管2的内壁接触，或者所述换热管1的端面通过支撑件5支撑集流管2的内壁或所述换热管2的端面与连接于集流管的支撑件5接触。支撑件5可以在捆扎换热器100之前焊接(例如点焊)固定在集流管2的管壁上，由此在利用捆扎带4捆扎集流管2，将组装的换热器100捆扎在一起，以进行焊接。支撑件5与集流管2的管壁的密封焊接可以与换热器100的其它部件的焊接同时进行。在捆扎换热器之前也可以将支撑件5过盈配合在集流管2上对应的孔中，或者在支撑件5和集流管2对应的孔上设置相互配合的螺纹，将支撑件拧入所述孔中。在本发明的一些示例中，所述换热管2的端面与连接于集流管的支撑件5接触，可以将条状件放置在支撑件5的头部52上，防止在捆扎换热器100时支撑件5掉落。将捆扎好的换热器放入炉内钎焊，支撑件5与集流管2的管壁的焊接可以与换热器100的其它部件的焊接同时进行，简化了步骤。
