Create a precise parametric 3D CAD model of a straight-fin aluminum heatsink with exact engineering dimensions. The model must follow these constraints strictly and numerically.
Overall dimensions:
Width: 40 mm
Depth: 40 mm
Total height: 15 mm
Base:
Thickness: 4 mm
Solid rectangular block
Size: 40 mm × 40 mm × 4 mm
Fins:
Quantity: EXACTLY 20 fins (not 19, not 21)
Fin height: 11 mm (measured from top surface of base)
Fin thickness: 0.8 mm
Fin depth: full 40 mm
Orientation: fins run parallel along the depth (40 mm direction)
Spacing:
Fin-to-fin spacing: 1.2 mm clear gap between each adjacent fin
Total pitch (center-to-center): 2.0 mm
Number of gaps: 19
Total fin width: 20 × 0.8 mm = 16 mm
Total gap width: 19 × 1.2 mm = 22.8 mm
Combined occupied width: 38.8 mm
Remaining margin: 1.2 mm total
Left margin: 0.6 mm
Right margin: 0.6 mm
Placement:
First fin starts 0.6 mm from left edge
Fins distributed using exact linear array with 2.0 mm pitch
Last fin must end 0.6 mm before right edge
Material:
Brushed aluminum (Alu

生成一个车载功放的3D模型，要求：功放产品由散热上壳，PCBA，底壳三部分组成，其中散热上壳使用ADC12材料，使用压铸工艺，外表面为散热鳍片，内表面有散热凸台与PCBA进行接触，且四周包裹PCBA。PCBA为绿色，上面存在连接器，芯片与高电容。底壳材料为AL5052，使用冲压工艺；
3D生成可参考网络上现有的车载功放产品，细节满足对应工艺需求且无干涉

一张清晰的结构示意图，展示一个单头加热管在金属模具内部的剖面图。视角是从模具板的侧面切开，看到内部构造。
主体是一个厚重的金属方块，剖面处有标准的斜剖面线。金属方块内部，一根细长的加热管紧紧嵌在孔中。加热管本身也是剖开的：最核心是一圈圈像弹簧一样的红色螺旋电热丝；中间层是密密麻麻的灰色细小颗粒（氧化镁粉）；最外层是紧贴孔壁的银色金属管。
画面的引线端（模具外部）伸出两根带陶瓷接头的导线。大箭头或标签线指示“电热丝”、“绝缘粉末”、“金属管壁”、“模具”，技术插图风格，白色背景，高清。
