技术领域
本申请涉及翅片弯曲技术领域，具体而言，涉及一种翅片及具有其的换热器。
背景技术
目前，现有技术中的部分换热器具有折弯段，换热器的扁管在折弯预留区会发生扭转以实现扁管的弯折。为了避免不便于对翅片进行弯折以及翅片在折弯时出现弯折不稳定的情况，一般在扁管的折弯预留区没有设置翅片，因而在换热器的折弯段形成了无翅片区域。
然而，在无翅片区域将会出现较大的缝隙，产生漏风，影响换热性能。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
如图1至图6所示，本申请的实施例一提供了一种翅片10，该翅片10包括第一连接段11、第二连接段12和第三连接段13，第二连接段12设置在第一连接段11和第三连接段13之间，第二连接段12用于进行弯曲，第二连接段12具有相对设置的第一连接端和第二连接端，第一连接端设置在第二连接端远离第三连接段13的一侧；沿第一连接端至第二连接端的延伸方向为第二连接段12的长度方向。沿第二连接段12的长度方向，第二连接段12能够发生弯折变形，以使直条结构的第二连接段1)在弯曲后为形成弧形条结构，也可以理解为：第二连接段12在弯曲前为直条结构，第二连接段12在弯曲后为弧形条结构。
采用这样的结构，能够便于使得第二连接段12在长度方向进行适应性的弯曲，以形成弧形条结构，避免第二连接段12发生严重扭曲变形。
第二连接段12为波纹结构，沿第二连接段12的波谷位置至第二连接段12的波峰位置的方向为第二连接段12的高度方向，第二连接段12的高度方向和第二连接段12的长度方向均垂直于第二连接段12的宽度方向。其中，第二连接段12上设置有第一开窗口141，第一开窗口141为条形口，第一开窗口141沿第二连接段12的宽度方向延伸。具体地，TW为翅片宽度对应的英文单词的缩写，TW代表翅片的宽度，附图中TW方向代表宽度方向。
采用本实施例提供的翅片10，由于第二连接段12上的第一开窗口141沿第二连接段12的宽度方向延伸，这样使得翅片10具有沿第二连接段12的宽度方向延伸的间隙，当第二连 接段12在长度方向被弯曲时，由于第一开窗口141的延伸方向与第二连接段12的长度方向垂直，使得第一开窗口141会随第二连接段12在长度方向上的变形而发生变形，也就是说，第二连接段12在长度方向被弯曲的过程中第一开窗口141处就会适应性地拉伸和收缩变形，即第一开窗口141能够随着第二连接段12的弯曲变形进行拉伸和收缩，便于对第二连接段进行弯曲并形成弧形条结构。由此可知，通过在翅片10上增加开窗的结构，有效地增加了翅片的弯曲变形量，便于对第二连接段12在长度方向上进行弯曲，避免了翅片在弯曲变形过程中结构发生严重扭曲变形。因此，上述结构第一开窗口141会发生适应性的变形，便于对第二连接段12进行弯曲并形成弧形条结构，也便于第二连接段12在弯曲时第一开窗口141能够较大程度上维持开窗状，避免弯曲作用力的浪费；同时第一开窗口141还能够便于有效提高换热效果。此外，通过设置待弯曲段结构，也能够避免出现无翅片10区域，减小了漏风情况，有效保证了换热性能。本实施例中的翅片10能够提高产品的迎风面积，折弯区域也有翅片10增强换热，整体换热能力加强；加强产品防腐能力，延长了产品寿命，提升了可靠性。保证产品整体美观性。折弯加工方便，效率高。
需要说明的是，在弯曲时，折弯滚轮与换热器的换热扁管40接触，换热扁管40被折弯并弯曲成U形结构，且换热扁管40在U形处具有一定的扭曲变形，以便于使得板状结构的换热扁管40的板体能够形成有效遮挡。同时换热扁管40带动与换热扁管40连接的翅片10进行弯曲，具体为第二连接段12发生弯曲，并使得第二连接段12弯曲成U形，且第二连接段12具有一定的扭曲变形，以便于使得第二连接段12能够形成有效遮挡。如图7至图10所示，换热器弯曲成双排结构。或者如图11至图13所示，换热器弯曲成A型结构。
本实施例中的第一连接段11和第三连接段13可以均与第二连接段12连接设置。或者，第一连接段11和第三连接段13均与第二连接段12间隔设置，这样在弯曲时能够使得第二连接段12具有一定的弯曲变形空间，便于第二连接段12的弯曲变形。
本实施例中的第一开窗口141可以为多个，多个第一开窗口141间隔设置在第二连接段12上。采用这样的结构设置，通过多个第一开窗口141能够便于进一步提高换热效果，也便于第二连接段12的弯曲成型，避免第一开窗口141在弯曲时发生变形，避免弯曲作用力的浪费，便于顺利进行弯曲。
在一个实施例中，可以使多个第一开窗口141沿第二连接段12的长度方向间隔设置，这样便于优化第一开窗口141的排布，提高第一开窗口141的个数，以便于有效进行换热。同时也不会出现因第二连接段12弯折导致第一开窗口141变形的情况。
在另一实施例中，可以使多个第一开窗口141沿第二连接段12的宽度方向间隔设置，采用这样的结构设置，能够沿第二连接段12的宽度方向并排设置多个第一开窗口141，避免第一开窗口141沿第二连接段12的宽度方向延伸过长导致结构不稳定的情况，提高了第二连接段12的结构稳定性。
在又一实施例中，可以使多个第一开窗口141形成多个第一开窗组，多个第一开窗组中的各个第一开窗组均包括多个沿第二连接段12的长度方向间隔设置的第一开窗口141，多个 第一开窗组沿第二连接段12的宽度方向间隔设置。采用这样的多个第一开窗组的结构，能够便于增加第一开窗口141的布置范围和位置，也不会使得第一开窗口141在弯曲时发生较大的变形，从而便于有效进行弯折。此外，采用这样的结构布局，还能够有效保证第二连接段12的结构强度。
在本实施例中，第二连接段12上还设置有第二开窗口142，第二开窗口142与第一开窗口141间隔设置，第二开窗口142为条形口，第二开窗口142沿第二连接段12的长度方向延伸。采用这样的结构设置，通过设置第二开窗口142能够便于保证第二连接段12在长度方向上结构强度，增加弯曲的部分阻力，避免弯折过渡失控的情况。
具体地，本实施例中的第二开窗口142为多个，多个第二开窗口142间隔设置，以更好地避免第二连接段12弯曲过渡变形的情况。
在本实施例中，多个第二开窗口142沿第二连接段12的宽度方向间隔设置。采用这样的结构设置，能够便于更好地保证第二连接段12在长度方向上的结构强度，避免翅片10因弯曲过渡变形失效的情况。
具体地，第二开窗口142设置在第一开窗口141的端部。采用这样的结构设置，能够便于有效通过第二开窗口142提高结构的强度，减小弯曲变形失控的情况，同时优化了开窗结构的结构布局，便于有效进行换热。
本实施例中的第一开窗口141可以为多个，多个第一开窗口141形成多个第一开窗组，多个第一开窗组中的各个第一开窗组均包括多个沿第二连接段12的长度方向间隔设置的第一开窗口141，多个第一开窗组沿第二连接段12的宽度方向间隔设置。可以在多个第一开窗组的相邻两个第一开窗组之间设置有至少一个第二开窗口142，以有效保证结构强度，避免弯曲变形失效的情况。或者，在第二开窗口142为多个，多个第二开窗口142中的至少一个第二开窗口142设置在多个第一开窗组的一端，多个第二开窗口142中的至少一个第二开窗口142设置在多个第一开窗组的另一端，以有效保证两端的结构强度，避免弯曲失控的情况。
在本实施例中，第一连接段11和第三连接段13均为波纹结构，第一连接段11具有第一波距Fp1，第二连接段12具有第二波距Fp2，第三连接段13具有第三波长波距Fp3；其中，Fp2＞Fp1，Fp2＞Fp3。采用这样的结构设置，能够便于翅片10的弯曲变形。这样使得翅片10产品在疏翅区域进行折弯，折弯可行性高，可以折出一定角度或者对折。采用本实施例提供的翅片10，通过使第二波距大于第一波距、第二波距大于第三波距，使得第二连接段12形成疏翅区，在第二连接段12处的翅片10波纹弯折平缓，降低了工艺加工难度，便于进行弯折，避免因翅片10弯折程度大导致弯折时受力较大，避免对第二连接段12的翅片10造成损害的情况。此外，通过第二连接段12能够提高空气侧换热面积，进而提高整体换热器的换热能力。因此，采用本实施例提供的翅片10，能够解决现有技术中不便于对翅片10进行弯折的技术问题。
需要说明的是，在弯曲时，折弯滚轮与换热器的换热扁管40接触，换热扁管40被折弯并弯曲成U形结构，且换热扁管40在U形处具有一定的扭曲变形，以便于使得板状结构的换 热扁管40的板体能够形成有效遮挡。同时换热扁管40带动与换热扁管40连接的翅片10进行弯曲，具体为第二连接段12发生弯曲，并使得第二连接段12弯曲成U形，且第二连接段12具有一定的扭曲变形，以便于使得第二连接段12能够形成有效遮挡。如图7至图10所示，换热器弯曲成双排结构。或者如图11至图13所示，换热器弯曲成A型结构。
优选地，本实施例中的2Fp1≤Fp2≤6Fp1，2Fp1≤Fp2≤6Fp1，这样能够使得第二连接段12处于合适的范围内，便于第二连接段12进行弯曲。
需要说明的是，在第二连接段12进行弯曲折弯后，第二连接段12将存在部分扭曲情况，且相邻两片之间也会存在压塌情况。
在本实施例中，第二连接段12的长度方向和第二连接段12的高度方向均垂直于第二连接段12的宽度方向，沿第二连接段12的宽度方向第二连接段12的宽度为Fw2，第一连接段11的宽度为Fw1，第三连接段13的宽度为Fw3；其中，Fw1＝Fw2＝Fw3。采用这样的结构设置，便于进行生产制造，减小了生产难度。
具体地，本实施例中的第二连接段12的长度为BL(BL为折弯长度对应的英文单词的缩写)，第二连接段12的宽度为Fw2；其中，1.5Fw2≤BL≤5.5Fw2。采用这样的结构设置，能够便于使得第二连接段12具有足够的延伸长度，以便于使得第二连接段12的波纹弯折平缓，从而便于对第二连接段12在长度方向上进行弯折，便于生产制造。具体地，当长度小于1.5Fw2时，容易出现折弯损坏翅片10的情况；当长度大于5.5Fw2时，使得第二连接段12(第二连接段12可以理解为疏翅段)太长进而会影响翅片10单位面积换热能力，使得换热能力下降。具体地，Fw为翅片宽度对应的英文单词的缩写，Tw为扁管宽度对应的英文单词的缩写，Fw和Tw分别代表宽度值。
在本实施例中，第二连接段12的宽度为Fw2，第二连接段12的弯曲半径为R弯；其中，2Fw2≤R弯≤7Fw2。采用这样的结构设置，能够便于有效对第二连接段12进行弯折，避免因弯曲半径过小带来不便于弯折的情况，也避免因弯曲半径过大影响整体布局的情况。同时，通过设置在该尺寸范围内，能够降低工艺加工的难度。
具体地，第一连接段11与第二连接段12间隔设置，以便于第二连接段12在受到弯曲时能够在第一连接段11和第二连接段12之间的间隙内有一定的伸展空间，避免第一连接段11对第二连接段12的变形限制，便于第二连接段12靠近第一连接段11的部位发生弯曲变形。或者，第三连接段13与第二连接段12间隔设置，以便于第二连接段12在受到弯曲时能够在第三连接段13和第二连接段12之间的间隙内有一定的伸展空间，避免第三连接段13对第二连接段12的变形限制，便于第二连接段12靠近第三连接段13的部位发生弯曲变形。或者，第一连接段11和第三连接段13均与第二连接段12间隔设置，以便于第二连接段12在受到弯曲时能够在第一连接段11和第二连接段12之间的间隙以及第三连接段13和第二连接段12之间的间隙内具有一定的伸展空间，避免第一连接段11和第三连接段13对第二连接段12的变形限制，以便于第二连接段12的整体变形。
优选地，本实施例中的第一连接段11和第三连接段13均与第二连接段12间隔设置，以便于第二连接段12的弯曲变形。具体地，第一连接段11与第二连接段12之间的距离为Gap1，第三连接段13与第二连接段12之间的距离为Gap2。
本实施例中的第一连接段11和第二连接段12之间具有第一间隙Gap1，第二连接段12和第三连接段13之间具有第二间隙Gap2；其中，Gap1＞0；和/或，Gap2＞0。
具体地，第一连接段11的高度为Fh1，第二连接段12的高度为Fh2，第三连接段13的高度为Fh3；其中，Fh2≤Min(Fh1，Fh3)。采用这样的结构设置，能够便于形成第二连接段12和第一连接段11、或者第二连接段12和第三连接段13之间具有高度差，通过高度差的设置也便于对第二连接段12进行弯曲。同时，这样使得第二连接段12没有焊接到扁管上，从而便于进行弯曲。
具体地，可以使Fp1＝Fp3。采用这样的结构设置，便于使得第一连接段11和第三连接段13形成一样的结构，以便于生产制造。
具体地，可以使Fh1＝Fh3。采用这样的结构设置，能够便于使得第一连接段11和第三连接段13形成一样的结构，便于进行生产制造。
在第一实施例中，翅片10为采用和本体换热器一体化的一整条翅片10，但又为了方便工艺加工和生产，一般的Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3。为了工艺加工和生产的可行性，一般的Fw1＝Fw2＝Fw3＝Tw且Gap1≥0和Gap2≥0。
为了工艺折弯便捷性，经过大量实验证明，一般的1.5Tw≤BL(疏翅区长度或叫做折弯区长度)≤5.5Tw)为最佳范围。
产品折弯半径和扁管宽度有一定的关系，满足，2Tw≤R弯(折弯半径)≤7Tw。
折弯后的产品夹角θ在0°到180°范围内都可以。
疏翅区域的翅片10高度Fh2≤Fh1，且Fh2≤Fh3，由于翅片10高度降低，中间折弯疏翅区域的焊接率降低或翅片10未完全焊接到扁管上是允许的。
这样，可以提高产品的迎风面积，折弯区域也有翅片10增强换热，整体换热能力加强；加强产品防腐能力(没有无翅扁管裸露)，延长了产品寿命，提升了可靠性。保证产品整体美观性。整体一条翅片10方便设备一次性加工翅片10；产品在疏翅区域进行折弯，折弯可行性高，可以折出一定角度或者对折。
在第二实施例中，两侧翅片10高度一致，两侧片距一致，中间翅片10高度降低。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3；Fw2＜Fw1＝Fw3且Gap1≥0且Gap2≥0。
在第三实施例中，两侧翅片10高度一致，两侧片距一致，中间翅片10高度加高。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3；Fw2＜Fw1＝Fw3。
在第四实施例中，两侧翅片10高度不一致，两侧片距一致，中间翅片10高度小于等于两边其中最低高度的翅片10。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3；Fw2≤Min(Fw1，Fw3)。
在第五实施例中，两侧翅片10高度不一致，两侧片距一致，中间翅片10高度大于等于两边其中最高的翅片10。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3；Fw2≥Max(Fw1，Fw3)。
在第六实施例中：两侧翅片10高度不一致，两侧片距一致，中间翅片10高度大于两边其中最低翅片10，小于最高翅片10。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＝Fp3；Min(Fw1，Fw3)＜Fw2＜Max(Fw1，Fw3)。
在第七实施例中：符合以上任意替代方案要求，且两侧片距允许不一致也在本专利保护范围内。
Fp2＞Fp1且Fp2＞Fp3，同时Fp1＞Fp3或Fp1＜Fp3。
在第八实施例中：弯折区域的翅片10从中间至两端逐渐稀疏，以应对折弯区域的变形量。
如图3至图6所示(附图中的Tw方向即为翅片10的宽度方向)，在上述所有实施例中，第一连接段11、第二连接段12和第三连接段13上均设置有开窗结构(开窗结构可以包括第一开窗口141、第二开窗口142和第三开窗口143)，第一连接段11和第三连接段13上的开窗结构的开窗口均沿垂直于翅片10的宽度方向延伸。第二连接段12上的开窗结构的一部分窗口沿垂直于翅片10的宽度方向延伸，第二连接段12的开窗结构的另一部分窗口沿翅片10的宽度方向延伸，通过沿翅片10的宽度方向延伸的窗口能够便于第二连接段12进行弯曲，以更好地适应翅片10在长度方向上的变形。
具体地，在本实施例中在第一连接段11和第三连接段13上均设置有第三开窗口143，第三开窗口143为多个，各个第三开窗口143沿翅片10的长度方向(翅片10的长度方向与第二连接段12的长度方向相同)延伸，多个第三开窗口143沿翅片10的宽度方向(翅片10的宽度方向与第二连接段12的宽度方向相同)间隔设置，以便于提高换热效果。具体地，第一连接段11和第三连接段13可以为相同的结构。
本申请的另一实施例提供了一种换热器，本实施例中的换热器包括上述实施例提供的翅片10。换热器还包括换热扁管40、进口集流管20和出口集流管30，进口集流管20和出口集流管30分别设置在换热扁管40的两侧。换热扁管40为多个，相邻两个换热扁管40之间设置有翅片10。
在本实施例中，换热器还包括进口集流管20和出口集流管30，进口集流管20设置在翅片10的一端，进口集流管20的半径为R1；出口集流管30设置在翅片10的另一端，出口集流管30的半径为R2；其中，Fw2＜R1＜R2。采用这样的结构设置，能够降低介质在换热器内部的阻力，尤其进出口集管的阻力。
相邻两个换热扁管40的插接端的距离为Tp，可以使得Fh2＜Tp，以便于第二连接段12进行弯曲。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：提高产品的迎风面积，折弯区域也有翅片增强换热，整体换热能力加强，便于待弯折段进行弯折。

在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
