具体实施方式
下面结合图1～图6对本公开提供的技术方案进行更为详细的阐述。
参见图1，本公开实施例提供一种电控箱，包括箱本体1以及树形翅片2，树形翅片2设于箱本体1。
树形翅片2作为电控箱的主要散热翅片，散热面积大，散热效果好。除该树形翅片2外，比如电控箱还设置有其他结构形式的散热翅片。
树形翅片2比如有多种结构形式，比如为：由树干和单层或多层树枝形成，树枝比如为弧形、直线形，各同层树枝之间不相交。若树枝为弧形的，各树枝弧形的弯曲方向相同或不同，在一些实施例中位于树干部22同一侧的树枝部21的弯曲方向相同为例。
参见图1，箱本体1包括U形本体11和箱盖。U形本体11包括侧部和底部，树形翅片2设于U形本体11的底部外表面。U形本体11的侧部的内表面可设置第一辅助散热翅片111、外表面比如还设置第二散热翅片112，以辅助散热，后文还将详述此处。箱盖上比如设置肋型翅片，以进一步改善散热。U形本体11内、外表面的所有翅片都与U形本体11一体挤压成型。且位于U形本体11内外表面的散热翅片都可成排布置，一次挤压成型形成所有的散热翅片。
在一些实施例中，箱本体1除了包括U形本体11和箱盖之外，还包括两个端板，U形本体11为三侧开口的结构，箱盖、两个端板用于封堵开口以形成箱本体1。
下面详细介绍在一些实施例中使用的树形翅片2的结构。
参见图1，树形翅片2包括树干部20和树枝部21，树干部20设于箱本体1，树枝部21设于树干部20。
树枝部21比如根据需要设置为弧形、直线形，单层或多层。
图1所示为设置单级、多层树枝部21的情形，每个树干部20上形成有多个树枝部21，这些树枝部21都是第一级。可以理解的是，树枝部21可设置为多级，比如在图1所示的树枝部21上再设置第二级树枝部21、第三级、甚至更多级树枝部21。设置多级树枝部21时，整个树形翅片2的尺寸更大，散热面积也更大。实际应用中，根据电控箱所需要的散热面积确定树形翅片2的树枝层数及总高度。
在一些实施例中，树枝部21包括两层或两层以上，图1所示为每个树干部20上设置三层树枝部21。在电控箱整体尺寸不变的前提下，多层树枝部21使得散热面积更大，散热效果更好。
参见图1，树形翅片2还包括顶部22，顶部22与树干部22的尖端相连，顶部22具有尺寸大于树干部20尖端的平面。
顶部22垂直于树干部20且平行于箱本体1的散热底面，上述结构使得电控箱外部散热翅片防护好，不易刮伤使用者和损坏散热翅片。
参见图1，树形翅片2是多个，各树形翅片2的顶部22是平齐的。该结构使得树形翅片2不会形成凸起的尖端，便于放置电控箱。
参见图1，树形翅片2成排设于箱本体1的外表面。所有的树形翅片2与箱本体1的U形本体一体成型，且树形翅片2排布整齐，一次加工就能形成所有的树形翅片2。
可选地，树形翅片2是多个，各树形翅片2的结构、尺寸是相同的。该结构不仅使得电控箱整体结构整洁、比例合适。
可选地，树干部20从根部到尖端逐渐变薄。该结构的树形翅片2结构稳固可靠、质量轻便。
下面介绍树形翅片2可选的尺寸参数。
具体地，树形翅片2是多个，相邻两个树干部20的间距L为10mm-15mm。比如为10mm、11mm、12mm、13mm、14mm、15mm等。
可选地，树枝部21的厚度D为0.6mm-1.2mm。比如为0.6mm、0.7mm、1.0mm、1.13mm、1.14mm、1。2mm等。
可选地，相邻两个树枝部21之间的间距H为5mm-7mm，比如为5mm、6mm、7mm。
上述技术方案，电控箱整体散热性能较普通电控箱散热性能好，除了采用新型的树形翅片2作为主要散热翅片外，还通过在箱体侧面设置侧面散热翅片、面板上设置 面板散热翅片辅助散热。
在一些实施例中，电控箱是无风扇结构。树形翅片2包括顶部22、树枝部21和树干部20。树干部20垂直于箱本体1表面，作为树形翅片2的主干且承担主要散热任务；树干部20从底部到顶部由厚到薄。树枝部21由底面开始生长，向两边展开，呈一定弧度展开，树枝部21层数由具体情况而定，散热要求越高树枝部21层数增加，图1所示为三层树枝部结构。顶部22垂直于树干部20且平行于散热底面。上述结构使得电控箱外部散热翅片防护好，不易刮伤使用者和损坏散热翅片。树形翅片2拥有更大的散热面积，在翅片根部树枝部更有利于散热，其散热效果较传统散热翅片更佳，外加侧面散热翅片辅助散热较现有电控箱的散热性能有很大提高。并且，实现了全铝电控箱360°无死角散热设计。树形翅片2简单美观，配合整体电控箱黄金比例的造型更加美观。
进一步地，树形翅片2的数量为多个，位于边缘的树形翅片2设有安装结构，通过安装结构能将电控箱与地面或其他部件安装在一起。
安装结构比如为孔、凹槽等。设置安装结构后，在安装电控箱时，无需再在电控箱上焊接吊耳、安装座等部件。
为了整齐、稳固排布多个电控箱，树形翅片2的数量为多个，位于边缘的树形翅片2设有内凹部24，内凹部24能与另一个电控箱对应位置的内凹部24拼凑形成用于穿插导轨的凹槽，通过导轨能将两个电控箱并排连接在一起。通过凹槽，能将多个独立的电控箱连接在一起，使得各电控箱不易移位，保证了放置后电控箱位置的稳定性。
可选地，树形翅片2设于箱本体1的内部和/或外部。在一些实施例中，以将树形翅片2设于箱本体1外表面为例，这样不会占用箱本体1内部的空间。
参见图3至图5，箱本体1包括U形本体11和箱盖；U形本体11和箱盖之间设有密封件3。
在箱型材开口面两边预留安装防水凹槽113，装上密封件比如密封圈、密封条3满足了U形本体11和箱盖之间密封安装要求。
参见图6，在设计U形本体11时左右两侧壁厚基材厚度A为2mm-4mm，并在U形本体11左右两侧壁外面设计为第一辅散热翅片111，第一辅散热翅片111间距B有效为3mm-8mm最佳距离。
参见图6，在U形本体11左右两侧壁的内壁也设计了第二辅散热翅片112，相邻第二辅散热翅片112的间距C为1.5mm-2.5mm，散热效果好，散热面积大。
此处，树形翅片2、第一辅助散热翅片111及第二辅助散热翅片112都与U形本体11一体挤压成型，利用铝合金材料导热性，有效扩大了散热面积，达到U形本体11与各翅片共同散热效果且免连接安装。
参见图6，在设计U形本体11时后壁基材厚度M为7mm-10mm，既满足安装螺丝孔深度同时也为导热最佳厚度。在U形本体11后壁背面设计为树形翅片2，在同等体积散热器中，有效把散热面积最大化。散热翅片2间距有效为10mm-15mm较佳散热通道距离。树枝间散热通是5mm-7mm，树枝部片厚度D为0.6mm-1.2MM为理想散热状态。
上述各实施例中，箱本体1是热传导材质，具体为铝合金；和/或，树形翅片2是热传导材质，比如铝合金。
在一些实施例中，电控箱的横截面是矩形的，且宽与长的比例为黄金比例。电控箱箱体总宽度与总长度的比值为黄金比例，即0.618。
上述技术方案，树形翅片2与箱本体1的U形本体11一体挤压成型，利用铝合金材料导热性，有效扩大了散热面积，达到箱本体1树形翅片2共同散热效果且免连接安装；一体成形的工艺，避免了油漆或氧化层的阻隔，大大提高了导电性能，实现最大化有效接地。并且，有效减少了零部件与工人安装，节省了物料成本和人工成本，并提高生产效率。
下面介绍电器件在电控箱内的一种安装形式。
参见图2，根据PCBA6或其它电器件的定位孔位置在U形本体11后壁基材上设计对应的安装螺丝孔，通过螺丝4来固定器件或PCBA6，使发热的器件5紧贴在U形本体11底部上，以将发热的器件的热量传导到底部基材中并通过底部基材再传导到外部散热翅片上，以此达对发热器件有效散热降温效果。
当PCBA6或其它电器件在接地时通过电线7将PCBA6或其它电器件与U形本体11连接并用螺丝4固定。
参见图1和图6，本公开另一实施例提供一种树形翅片，该树形翅片比如用于上述实施例提供的电控箱。该树形翅片包括树干部20、树枝部21和顶部22，树枝部21与树干部20相连，顶部22与树干部22的尖端相连，顶部22具有尺寸大于树干部20尖端的平面。
树枝部21比如根据需要设置为弧形、直线形，单层或多层。
图1所示为设置单级、多层树枝部21的情形，每个树干部20上形成有多个树枝 部21，这些树枝部21都是第一级。可以理解的是，树枝部21比如设置为多级，比如在图1所示的树枝部21上再设置第二级树枝部21、第三级、甚至更多级树枝部21。设置多级树枝部21时，整个树形翅片2的尺寸更大，散热面积也更大。实际应用中，比如根据电控箱所需要的散热面积确定树形翅片2的树枝层数及总高度。
顶部22垂直于树干部20且平行于箱本体1的散热底面，上述结构使得电控箱外部散热翅片防护好，不易刮伤使用者和损坏散热翅片。
在一些实施例中，树枝部21包括两层或两层以上，图1所示为每个树干部20上设置三层树枝部21。在电控箱整体尺寸不变的前提下，多层树枝部21使得散热面积更大，散热效果更好。
树干部20的根部粗于其尖端。可选地，树干部20从根部到尖端逐渐变薄。该结构的树形翅片2结构稳固可靠、质量轻便。
参见图6，下面介绍树形翅片2可选的尺寸参数。
可选地，树枝部21的厚度D为0.6mm-1.2mm。比如为0.6mm、0.7mm、1.0mm、1.13mm、1.14mm、1。2mm等。
可选地，相邻两个树枝部21之间的间距H为5mm-7mm，比如为5mm、6mm、7mm。
在一些实施例中，树形翅片的材质是铝合金的。铝合金的树形翅片散热性能好。
本公开又一实施例提供一种散热结构，包括本公开任一技术方案所提供的树形翅片。散热结构比如为散热板等。
在本公开的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开保护范围的限制。
