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。Referring to Fig. 1, the tree fin 2 includes a trunk portion 20 and a branch portion 21, the trunk portion 20 is provided in the box body 1, and the branch portion 21 is provided in the trunk portion 20.
树枝部21比如根据需要设置为弧形、直线形，单层或多层。The branch portion 21 is, for example, curved, linear, or a single layer or a plurality of layers as needed.
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。Fig. 1 shows a case where a single-stage, multi-layered branch portion 21 is provided, and each of the trunk portions 20 is formed with a plurality of branch portions 21, which are all first stages. It can be understood that the branch portion 21 can be arranged in multiple stages, such as the second-level branch portion 21, the third-stage, or even more-level branches 21 on the branch portion 21 shown in FIG. When the multi-stage branch portion 21 is provided, the entire tree-shaped fin 2 has a larger size and a larger heat dissipation area. In practical applications, the number of branches and the total height of the tree fins 2 are determined according to the heat dissipation area required by the electric control box.
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。In some embodiments, the branch portion 21 includes two or more layers, and FIG. 1 shows three branches 21 on each trunk portion 20. Under the premise that the overall size of the electric control box is constant, the multi-layer branch portion 21 makes the heat dissipation area larger and the heat dissipation effect is better.
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。Referring to Figure 1, the tree fin 2 further includes a top portion 22 that is coupled to the tip end of the trunk portion 22 and that has a flat surface that is larger in size than the tip end of the trunk portion 20.
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。The top portion 22 is perpendicular to the trunk portion 20 and parallel to the heat dissipating bottom surface of the box body 1. The above structure makes the heat dissipating fins of the electric control box shielded well, and is not easy to scratch the user and damage the heat dissipating fins.
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。Referring to Figure 1, the tree fins 2 are plural, and the top 22 of each of the tree fins 2 is flush. This structure allows the tree fins 2 to not form a raised tip for easy placement of the electrical control box.
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。Referring to FIG. 1, the tree fins 2 are arranged in rows on the outer surface of the tank body 1. All the tree fins 2 are integrally formed with the U-shaped body of the box body 1, and the tree fins 2 are arranged neatly, and all the tree fins 2 can be formed in one process.
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。Alternatively, the tree fins 2 are plural, and the structure and size of each of the tree fins 2 are the same. The structure not only makes the overall structure of the electric control box neat and tidy, and the proportion is appropriate.
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。Optionally, the trunk portion 20 tapers from the root to the tip. The tree fin 2 of the structure is stable and reliable in structure and light in weight.

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。Specifically, the tree fins 2 are plural, and the pitch L of the adjacent two trunk portions 20 is 10 mm to 15 mm. For example, it is 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and the like.
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。Alternatively, the thickness D of the branch portion 21 is from 0.6 mm to 1.2 mm. For example, it is 0.6 mm, 0.7 mm, 1.0 mm, 1.13 mm, 1.14 mm, 1.2 mm, and the like.

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。According to the above technical solution, the overall heat dissipation performance of the electric control box is better than that of the ordinary electric control box, except that the new tree fin 2 is used as the main heat dissipating fin, and the side heat dissipating fins are arranged on the side of the box body, and the panel is arranged on the panel. The panel heat sink fins assist in heat dissipation.
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。In some embodiments, the electrical control box is a fanless structure. The tree fin 2 includes a top portion 22, a branch portion 21, and a trunk portion 20. The trunk portion 20 is perpendicular to the surface of the box body 1 as the trunk of the tree fin 2 and bears the main heat dissipation task; the trunk portion 20 is thick to thin from the bottom to the top. The branch portion 21 starts to grow from the bottom surface, spreads to both sides, and expands in a certain arc. The number of the branches 21 is determined by the specific situation. The higher the heat dissipation requirement, the higher the number of the branches 21, and the three layers of the branch structure are shown in FIG. The top portion 22 is perpendicular to the trunk portion 20 and parallel to the heat dissipating bottom surface. The above structure makes the heat-dissipating fins of the electric control box well protected, and is not easy to scratch the user and damage the heat-dissipating fins. The tree-shaped fins 2 have a larger heat-dissipating area, and are more favorable for heat dissipation in the branches of the fin roots, and the heat-dissipating effect is better than the conventional heat-dissipating fins, and the side-side heat-dissipating fins help the heat dissipation compared with the existing electric control box. There is a big improvement. Moreover, the 360 degree non-dead temperature heat dissipation design of the all-aluminum electric control box is realized. The tree-shaped fins 2 are simple and beautiful, and the shape of the overall electric control box is more beautiful.

After the installation structure is installed, it is no longer necessary to solder the lifting lugs, mounting seats and other components on the electric control box when installing the electric control box.
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。In order to arrange a plurality of electric control boxes neatly and stably, the number of the tree fins 2 is plural, and the tree fins 2 located at the edges are provided with inner concave portions 24, and the inner concave portions 24 can be corresponding to another electric control box. The inner recess 24 is pieced together to form a groove for inserting the guide rail, and the two electric control boxes can be connected side by side through the guide rail. Through the groove, a plurality of independent electric control boxes can be connected together, so that the electric control boxes are not easily displaced, and the stability of the position of the electric control box after the placement is ensured.

The shaped body 11 and the fins share a heat dissipating effect and are free from connection and installation.
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。Referring to FIG. 6, when the U-shaped body 11 is designed, the thickness of the rear wall substrate M is 7 mm to 10 mm, which satisfies both the installation screw hole depth and the heat conduction optimum thickness.

The ratio of the total width of the electrical control box to the total length is the golden ratio, which is 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。In the above technical solution, the tree-shaped fin 2 is integrally extruded with the U-shaped body 11 of the box body 1, and the heat dissipation property of the aluminum alloy material is utilized to effectively expand the heat dissipation area, thereby achieving the common heat dissipation effect of the tree-shaped fin 2 of the box body 1 and being free from Connection and installation; the integrated forming process avoids the barrier of paint or oxide layer, greatly improves the electrical conductivity and maximizes effective grounding. Moreover, it effectively reduces the installation of parts and workers, saves material costs and labor costs, and improves production efficiency.
