 本发明的实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
本发明实施例的核心构思之一在于，采用多种组合式铆接使组件以达到快速安装、结构牢固、散热均衡效率高的效果。
参照图2，本发明示出一种散热组件，包括：
基板10，所述基板10的平面上均布有多条相互平行的挡筋11，两相邻的挡筋11形成安装槽12；
散热齿板20，所述散热齿板20的底端向外侧直角折弯形成翅片21安装于所述安装槽12内，所述翅片21的底面与所述安装槽12的底面相贴合，所述翅片21上沿其长度方向均布有多个连接孔22；
铆接件23，所述铆接件23的两端分别为承压部24和连接部、中间为连接承压部24和连接部的过渡部，所述连接部与所述安装槽12的底面连接，所述过渡部的外周与所述连接孔22的内壁对应，所述承压部24位于翅片21的顶面上方、受压力后沿连接孔22的周向延展并与所述翅片21的顶面贴合。
上述实施例中，散热齿板20与翅片21一体成型，通过折弯处理，增加散热齿板20本身与基板10的接触面积，以增强与基板10连接的稳固性；安装槽12的槽宽可适配翅片21的宽度，以安装槽12的槽边限制翅片21左右位移，便于在压铆连接时提供限位的作用；翅片21作90度直角弯折，保证翅片21与安装槽12槽底贴合时，散热齿板20呈竖直设置，从而保证一个基板10上多个散热齿板20能均匀设置，以提高整体的散热性能。
通过铆接件23将翅片21连接在安装槽12内，通过对铆接件23的承压部24施加压力后，使铆接件23的体积向下压缩，内部沿四周涨开，与翅片21上的连接孔22紧密连接，同时，承压部24也受力变形，其承压部24超出翅片21顶面的部分受挤压后沿四周延展，进而将连接孔22顶部边沿盖住，进一步加强了翅片21与基板10的连接。
本实施例中，所述铆接件23的连接部与所述安装槽12的底面一体成型，也可以是通过焊接等方式在安装之前就已经连接牢固，每个所述铆接件23分别与每个所述连接孔22对应设置，通过将铆接件23与安装槽12一体成型设置，便于翅片21快速安装。
在本实施例中，又如图2，所述铆接件23为圆形柱，所述过渡部的外周与所述连接孔22的内壁对应贴合，圆形柱作为铆接件23最简单的结构，类似于铆钉结构，制造容易，圆形柱的顶部为承压部24，如图6，对其承压部24施加压力后，圆形柱的顶部发生塑性变形，形成类似于螺帽25的形状盖柱连接孔22的顶部边沿，内部向外膨胀，与连接孔22紧密贴合，实现与翅片21牢固连接，其安装快捷方便。
在本实施例中，如图3，所述铆接件23为矩形柱，所述过渡部的外周与所述连接孔22的内壁对应贴合，矩形柱的长边沿翅片21的长度方向排列，相较圆形柱而言，在该长度方向，矩形柱能够更好地起到限制作用。
铆接件23在保证翅片21能顺利安装的情况下，可以为多种形状。
在本实施例中，如图4、图5所示，所述承压部24的中部设有凹坑、边沿形成侧围，所述侧围上均布有多个缺口，当翅片21安装在安装槽12内时，已固定在安装槽12底面上的铆接件23的承压部24位于翅片21的顶面上方，为提高在施加压力时承压部24向周边快速均匀延展，提高连接效率，固在其承压部24中部设置凹坑，使边沿形成侧围，并在侧围上预先设置缺口，便于向外翻边，快速盖合翅片21，又如图7所示，侧围受到垂直压力后，快速向四周翻折并与翅片21顶面贴合，某种程度上，侧围受到压力与翅片21贴合后便可将散热齿板20紧固在安装槽12内，以减少继续施加的压力，避免翅片21部分材料受压过大出现变形，影响质量。
在本实施例中，所述散热齿板20的竖侧壁与相邻的挡筋11侧壁相贴合，安装好后的散热齿板20的翅片21底面与凹槽底面贴合，基板10受热热量可通过底面传输给散热齿板20，将基板10上的挡筋11（挡筋11、基板10和散热齿板20均为都为金属材质）即安装槽12的槽侧边与散热齿板20的侧壁贴合，可增大散热面积，提高散热效率。
进一步地，与所述散热齿板20的竖侧壁相贴合的挡筋11沿高度方向延伸设有扩热部13，所述扩热部13与所述散热齿板20的竖侧壁相贴合，扩热部13可与挡筋11自成一体，可以根据实际情况自由加装，与散热齿板20接触面越大则散热效果越好，但同时也要考虑整体重量以及相邻散热齿板20之间的间隙，间隙过小则又导致散热效果不佳。
在本实施例中，如图8，所述安装槽12的底面上设有与所述连接孔22相对应的安装孔14，所述连接部、过渡部分别与所述安装孔14、连接孔22过盈配合，所述承压部24上设有螺帽25，即安装前，铆接件23与安装槽12分开设置，散热齿板20和基板10上的孔位均可一体加工成型，加工效率更高，安装前，铆接件23与安装孔14和连接孔22为过盈配合，以便在铆接件23受压前跑偏，影响连接效果。
参照图2至图8，本发明还公开了一种散热组件的安装方法，包括：
S1，铆接件23与所述安装槽12一体成型时，将翅片21底部平行于安装槽12底面上方，使每个连接孔22与相对应的铆接件23同时共轴线；
安装槽12内设有安装孔14时，将翅片21底部平行于安装槽12底面上方，使每个连接孔22与相对应的安装孔14同时共轴线；
S2，沿轴线将翅片21以及散热齿板20放置在安装槽12内，铆接件23或安装孔14与连接孔22相对应，翅片21的底面与安装槽12的底面贴合；
S3，若安装槽12内设置的是安装孔14，则将多个铆接件23的连接部分别穿过多个连接孔22放置在相对应的安装孔14内；
若安装槽12内设置的是铆接件23，则铆接件23直接位于连接孔22内；
S4，对安装槽12最侧边的铆接件23的承压部24施加压力，使翅片21的侧端与基板10铆接完成；
S5，从安装槽12的中部沿侧边依次对承压部24施加压力，逐步将翅片21与基板10完全铆接。
其中，所述铆接件23采用316L不锈钢材质。
