这是一系列带集成安装底座的CNC加工铝散热器,专为需要平整、稳定热界面且无需二次组装的工程师设计。我们将底座平面度控制在0.05 mm(覆盖整个接触区域),所有安装孔的位置公差为±0.01 mm。每件产品均从我们东莞工厂在10天内发货,我们提供无起订量政策,您可以根据自己的节奏进行打样或批量生产。

为什么安装底座能消除热界面失效

大多数挤压铝散热器在不平整的PCB表面会晃动,产生气隙,破坏导热性能。我们的安装底座与散热鳍片阵列在同一装夹中加工,确保底座与鳍片完全垂直。这种一体式结构在大多数应用中无需导热胶带或夹紧框架。您可以在底座上获得一致的0.02 mm表面轮廓,这意味着您的导热垫或导热膏的性能完全符合其数据表承诺。

我们使用的材料与热处理

我们常备6063-T5和6061-T6铝合金,其中6063的布氏硬度最低为80 HRC,6061为95 HRC。对于高振动环境,我们提供硬质阳极氧化选项,可将表面硬度提升至300 HV,并增加800 VDC的介电击穿电压。每笔订单均附带原材料证书,我们可追溯至铸造厂的熔炼批次。

与您的热模型匹配的加工公差

您的仿真假设了特定的接触压力和平面度。我们按此假设交付。底座厚度公差为±0.05 mm,鳍片间距公差为±0.1 mm,配合表面加工至Ra 0.8 µm。如果您的设计使用热管或均温板,我们可以加工深度公差为±0.02 mm的凹槽,以确保完全接触。如需深入了解我们如何控制这些变量,请阅读我们的CNC加工公差指南

鳍片几何选项:直齿、铲齿和交错齿

直齿鳍片是我们自然对流的标准配置。铲齿鳍片在强制气流下可提供每体积高20%的表面积。交错针状鳍片可破坏边界层,在高风速风道中可将传热效率提升最多15%。我们可以在同一安装底座上组合任意这些几何形状,无需额外刀具成本。我们的CNC切削刀具根据鳍片间距选择,您可以查看我们的CNC切削刀具选择指南,了解我们如何防止薄鳍片产生毛刺。

表面处理与阳极氧化:防腐与电气隔离

我们提供三种表面处理。透明阳极氧化(8-12 µm)适用于标准室内环境。黑色阳极氧化(18-20 µm),发射率为0.85,适用于辐射传热。硬质阳极氧化(50 µm)适用于户外或化学暴露环境。所有阳极氧化均在厂内完成,与外包阳极氧化相比,交期缩短5天。如果您需要裸露铝以获得最大导热性,我们还会对安装底座接触区域进行遮蔽。

每次发货前的检验

每件散热器均通过测量不确定度为±1.5 µm的三坐标测量机(CMM)检测。我们对100%的零件测量底座平面度、孔位、鳍片高度和表面粗糙度。随货附送包含实际测量值的数字检验报告。如果任何尺寸超出您的图纸公差,该零件将被报废而非返工——因为我们知道返工零件带有隐藏应力和表面损伤。

防止运输中鳍片损坏的包装

鳍片很脆弱。我们使用定制瓦楞纸内衬,将每件散热器固定在刚性槽内,底座侧配有ESD泡沫。零件密封在带有干燥剂的防静电袋中。对于超过500件的订单,我们使用真空成型托盘,可直接从箱中进行自动化取放。从1.2米高度的跌落测试显示,使用我们的标准包装时鳍片零变形。

带安装底座的铝散热器系列的最小起订量是多少?

无起订量——我们接受单件订单用于打样,并可扩展至数千件,且不改变您的单价结构。

你们能否根据我的PCB布局定制安装底座的孔位模式?

可以,我们可根据您的STEP文件加工任何孔位模式、沉孔或螺纹镶件,并可添加定位销以支持自动化装配。

你们如何确保阳极氧化后底座保持平整?

我们使用专有的挂架系统,在阳极氧化过程中将底座固定在精密夹具上,并在涂层后重新检验平面度,确保其保持在0.05 mm以内。

定制散热器设计的典型交期是多久?

标准设计10天发货;带新刀具的定制几何形状需15-18天,包括首件检验。

我们是一家位于中国东莞的精密制造工厂,拥有20年的CNC加工、冲压和弹簧生产经验。带安装底座的铝散热器系列在中国制造,受ISO 9001:2015体系管控。立即发送您的图纸,12小时内获取确定报价。
