核心结论

铝制散热块采用6063-T5铝合金,热阻0.62 K/W,翅片1.0 mm、片距3.0 mm,底板厚1.0 mm,平面度0.10 mm/100 mm。冲压一体成型,5万件批量内片距±0.05 mm,一般尺寸±0.15 mm,关键尺寸±0.05 mm。标配黑色阳极氧化Type II 10-15 µm,单件重650克,适配LED工矿灯2.0 m/s强制风冷。

面向 LED 工矿灯 设计的该 铝制散热块,6063-T5 铝合金 热阻为 0.62 K/W。翅片实测 1.0 mm、片距 3.0 mm,底板厚 1.0 mm,出货前平面度确认到 0.10 mm/100 mm。

设计思路与工艺

冲压可稳定实现挤出无法保持的 1.0 mm 翅型:模具一次行程成型全部翅片,因此在 5 万件 批量内片距始终控制在 ±0.05 mm。

底板与翅片一体冲压成型,不存在钎焊接头失效风险。安装面 0.10 mm/100 mm 的平面度直接由模具保证,使界面材料的接触更均匀。

一体式结构省去了双件式散热器的胶层,缩短热传导路径。6063-T5 铝合金 与气流之间只隔着冲压表面本身,没有中间介质。

冲压结构对抗批次波动的能力优于挤出:模具磨损首先表现为可测量的片距漂移,检测环节通过 三坐标 + 100% 液压机气密测试 就能发现,无需等到客户端。

冲压 6063-T5 铝合金 让 铝制散热块 保持轻量,按包络不同重量为 650 克,同时不牺牲翅片密度——这在机箱风道长度已固定的场合尤其关键。

材料选择与表面处理

标准材料为 6063-T5 铝合金,标配表面处理 黑色阳极氧化 Type II,10-15 µm。若服役环境存在 LED 工矿灯 工况腐蚀顾虑,我们建议走钝化路线;若导热优先于重量,则改用紫铜 C110,热性能提升的同时单件重量约翻倍。

可选公差等级

一般尺寸按 ±0.15 mm 控制,±0.05 mm(底板厚度) 等关键特征单独管控。成型几何继承模具重复精度 ±0.05 mm,孔位控制在 ±0.15 mm。更严等级需要增加一道冲压工序,因此在开模前而非开模后决定更划算。

出货前检验

每批附 三坐标 + 100% 液压机气密测试 出具的三坐标报告,记录平面度、片距、底板厚度与孔位,超出 ±0.15 mm 的零件在离开产线之前即被标记。

另请参阅:BQUQ挤压铝散热器系列 – 精密CNC精加工,无起订量。

抽样标准为关键尺寸 AQL 0.65、一般尺寸 1.5,每件首件套 measurement 由 三坐标 + 100% 液压机气密测试 执行。超出 ±0.15 mm 会触发整批全检。

成型后我们检查 1.0 mm 翅尖的毛刺与开裂——冲压可能在未改变任何图纸尺寸的情况下撕裂翅根。毛刺限值按零件单独设定。

最终防护方式为 PE 袋 + 出口纸箱,每箱 20 kg。每箱标注批次、数量与检验状态,记录按 ISO9001 文件要求保存 10 年。

应用场景

当 铝制散热块 在 LED 工矿灯 批量下运行时,一致性决定售后返修率。5 万件 生产中 ±0.05 mm 的稳定性让热曲线始终落在同一带宽内。

LED 工矿灯 的包装与振动要求推动结构设计走向一体成型。冲压 铝制散热块 没有会蠕变的胶层,而这正是双件式散热器的典型失效模式。

FAQ:下单前常见问题

可以针对我们的应用定制 铝制散热块 吗?

可以。提供图纸或样品,我们在 3 个工作日内回复 DFM 说明。大多数 LED 工矿灯 定制仅调整 3.0 mm、1.0 mm 或孔位排布,三项都属于现有 110 吨 压力机的改模,无需新增设备。

铝制散热块 的交期多久?

图纸确认后打样周期 72 小时;首件签样后量产周期 12 个工作日。新品开发模具周期 。我们按 EXW 工厂交货 报价,订舱后海运到欧洲约 25 至 30 天。

模具多久需要更换?

在 6063-T5 铝合金 与常规冲压吨位下,模具寿命约 ;按 5 万件 计算约 6 至 12 个月。我们为 LED 工矿灯 项目就地备用模具组,出现平面度异常时无需等待。

可以要求组装后交付吗?

可以。我们可增加卡扣、螺丝或风扇导风罩作为组件包,按套分装贴标。这在 LED 工矿灯 项目中较为常见,约增加 3 个工作日。

有哪些质量认证?

工厂通过 ISO9001 认证,可按需提供 RoHS 与 REACH 声明;封柜前可安排第三方 SGS 验货,这也是多数 LED 工矿灯 采购方的指定流程。

生产与交付

产线位于东莞同一 ISO9001 工厂内。110 吨 压力机群覆盖该 铝制散热块 系列,目前月承诺产能为 5 万件。

我们的 LED 工矿灯 经验可回溯至 2015 年首个模具项目。正因为这段积累,标准 黑色阳极氧化 Type II,10-15 µm 与 ±0.15 mm 的标定偏保守而非乐观。

工厂通过 ISO9001 认证,可随 PE 袋 + 出口纸箱,每箱 20 kg 提供 RoHS 与 REACH 文件;如需第三方 SGS 验货,可在封柜前安排。
