请参见图1-3，本申请提供一种翅片结构100，应用于微通道换热器中，与换热管插接配合，用于增大换热器与空气的接触面积，提升换热效率。
一种翅片结构100，翅片结构100开设有扁管槽10，扁管槽10贯穿翅片结构100的侧部以形成开口12，扁管槽10中穿设有扁管，扁管从开口12处插入扁管槽10内，扁管供介质流动，以与翅片结构100配合对空气进行吸热或放热；
翅片结构100包括多个倾斜段20，多个倾斜段20均从翅片结构100的一端延伸至另一端，多个倾斜段20依次首尾连接，构成波浪形状，倾斜段背向的两侧面均为相对于开口12的朝向倾斜设置的倾斜面。
如此设置，空气流经波浪形状的翅片结构100能够在总宽度不变的情况下，使空气在翅片结构100表面的流动路径变长，延长空气与翅片结构100表面接触的时间，增大空气与翅片结构100的接触面积，从而提高换热效率，波纹状的翅片还会增强空气流动受到的阻力，使空气流速减缓，同样能够提高空气在翅片结构100表面停留的时间，提升换热效率；此外，由于倾斜段20从翅片结构100的一端延伸至另一端，所以排水会更加顺畅，防止水分停留甚至凝结在翅片上。
可以理解地，请参见图1，本申请所述的开口12朝向的方向为开口12朝向远离扁管槽10的槽底的方向。
具体地，请参见图2，多个倾斜面21与开口12朝向的方向的夹角α为5°-20°，例如5°、8°、12°、13°、15°、18°或20°，如此设置能够使倾斜面21的斜度处于合理值，若倾斜角度小于5°，则翅片结构100对于换热效率的提升不大；若倾斜角度大于20°，则对于外部吹风元件的功率要求过高，功率损耗也过大，同时倾斜角度过大，扁管与翅片结构100组装时存在变形的风险。
可以理解地，此处的夹角是指倾斜面21与扁管槽10之间形成的最小正角，在本实施例中，夹角α体现为锐角。
进一步地，多个倾斜面21与开口12朝向的方向的夹角均相同。如此设置，翅片结构100的成型更为方便，降低了工艺成本，并且装配的过程中，多个翅片结构100的一致性更好。
可选地，倾斜面21与开口12朝向的方向的夹角α均为8°。在该倾斜度下，换热效率和对外部吹风元件的功率要求的比例达到最佳。
在一实施例中，靠近扁管槽10的倾斜面21与开口12的朝向的夹角小于远离扁管槽10的倾斜面21与开口12的朝向的夹角，从而提高翅片结构100与空气的换热效率，具体地，在本实施例中，倾斜面21靠近扁管槽10的一侧为迎风侧，远离扁管槽10的一侧为背风侧，空气中的水分易于在远离扁管槽10的背风侧处凝结，并且沿着背风侧的倾斜面21流淌和滴落，便于排水。
倾斜面21之间的连接曲率连续。如此设置，翅片结构100表面更加光滑，减少灰尘累积，使液体的流动更加流畅。
曲率连续是指各个倾斜面21之间通过光滑的过渡段连接起来，倾斜面21之间的连接不存在不连续的落差。
翅片结构100包括三个、四个或五个倾斜段20。倾斜段20数量的增加能够使翅片结构100表面的波峰和波谷数量更加密集，也就进一步增加了空气的流动路径、提高了翅片结构100与空气的接触面积以及对于空气的流动阻力等等因素，从而提高翅片结构100的换热效率，当翅片结构100的倾斜段20为三个时，能够降低对于外部吹风元件的功率要求，翅片结构100的倾斜段20为五个时，则能够提高翅片结构100的换热效率。
翅片结构100通过折弯工艺形成波浪形状。如此设置，翅片结构100通过本身材质弯折成型，无需另外增设结构，减少耗材，降低成本。
当然，可以理解地，翅片结构100也能通过其他工艺形成波浪形状，例如冲压工艺。
请参见图3，扁管槽10的内壁形成有翻边，翻边包括第一翻边40和第二翻边50，第二翻边50环绕于扁管槽10的边缘，第一翻边40设置在第二翻边50上，以加强翻边的强 度。第二翻边50与扁管抵接，能够增加翅片结构100与扁管之间的接触面积，从而提高两者连接的稳固性，同时第二翻边50能有效控制换热器多个翅片结构100之间的间距，便于换热器的组装。
扁管槽10的边沿处设有凸起30，凸起30设置在第一翻边40上，凸起30朝向与开口12朝向的方向垂直的方向延伸。如此设置，方便多个翅片结构100与扁管配合时，相邻多个翅片结构100之间的间距控制，也能保证多个翅片结构100之间的间距一致性。
凸起30朝向相邻的翅片结构100的表面为平面，能够更好地与相邻的翅片结构100的侧面贴合。
凸起30为多个，相邻的翅片结构100上的凸起30可以互相抵接，也能够交错设置，从而调整相邻翅片结构100之间的间距。
扁管槽10的槽口处设有引导段11，引导段11与扁管槽10的内壁连接，能够在扁管装配时，引导其方向，便于扁管插入扁管槽10中。
在一实施例中，引导段11为斜面，通过倒角形成，在其他实施例中，引导段11还可为弧面，通过倒圆角形成。
请参见图4，本申请还提供一种换热器200，包括如上所述的翅片结构100。
相较于相关技术，本申请提供的翅片结构100通过波纹式的设计，空气流经波浪形状的翅片结构100能够在总宽度不变的情况下，使空气在翅片结构100表面的流动路径变长，延长空气与翅片结构100表面接触的时间，增大空气与翅片结构100的接触面积，从而提高换热效率，波纹状的翅片还会增强空气流动受到的阻力，使空气流速减缓，同样能够提高空气在翅片结构100表面停留的时间，提升换热效率；此外，由于倾斜段20从翅片结构100的一端延伸至另一端，所以排水会更加顺畅，防止水分停留甚至凝结在翅片上。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
