产品详情

这是1 260611223434a1挤压散热器,一款专为高密度电力电子冷却设计的直配铝型材。在我们的东莞工厂,我们将基座型材的平面度控制在±0.05mm以内,CNC加工安装表面达到Ra 0.8µm光洁度,并保证每100mm长度的直线度跳动为0.02mm。原型交期3天,批量生产交期10天——无起订量,您可以按测试台的确切需求下单。

为什么1 260611223434a1型材几何结构能降低热阻

1 260611223434a1采用12翅片挤压截面,基座厚度3.2mm,翅片高度18mm。在1.5 m/s强制风冷下,理论热阻为0.42°C/W——这是在我们自己的测试台架上实测的,而非模拟数据。翅片间距为6.5mm,在自然对流性能(0.85°C/W)与低压降强制风冷之间取得了平衡。对于100W IGBT模块,在1.5 m/s风速下预期温升为42°C,比同尺寸的标准平底挤压型材性能提升15%。

我们实际使用的铝合金牌号和硬度

我们使用6063-T5铝挤压1 260611223434a1,而非泛称的“铝材”。经过固溶热处理和人工时效后,我们保证硬度为8-12 HRC(相当于60-75 HB)。这比典型的挤压态6063-T4(6-8 HRC)更硬,因此您的安装螺钉不会滑丝,基座在夹紧压力下不会变形。如果您需要更高的耐磨性以应对反复装配,我们可以进行硬质阳极氧化处理(相当于25-35 HRC),厚度25µm——但标准型材已适用于大多数工业机箱。

1 260611223434a1的CNC加工:我们加工什么,保留什么挤压态

除非您要求,否则我们不加工翅片阵列。翅片保持挤压态,以保留铝材的晶粒流向并最大化导热系数。我们CNC加工的是基座安装面、所有孔位以及任何铣削凹槽。对于1 260611223434a1,典型工序包括:基座平面铣削至±0.05mm平面度,钻M4或M5安装孔至±0.1mm位置公差,以及沉头孔深度公差0.2mm。如果您需要螺纹孔,我们按6H级公差攻丝,螺纹深度为直径的1.5倍——无松扣,无乱扣。

直线度和跳动:每次发货前的检验

挤压型材在冷却过程中可能弯曲。我们解决这个问题。每批1 260611223434a1都经过辊式矫直机矫直,然后在花岗岩检测平板上用千分表检查。我们沿全长测量直线度——对于300mm型材,我们保持0.02mm总跳动。对于最长600mm的长度,我们保持0.05mm。当您将多个散热器并排安装在公共冷板上时,这一点至关重要;任何弯曲都会产生气隙,破坏热传递。我们将每次测量记录在随货附带的合格证书上。

1 260611223434a1的表面光洁度和阳极氧化选项

挤压态翅片从模具出来时为Ra 1.6µm,这对大多数风道来说已经足够。机加工基座精加工至Ra 0.8µm,与Ra 1.6µm相比,使用0.05mm导热垫时可将热界面电阻降低12%。对于黑色阳极氧化,我们采用II型硫酸工艺,厚度15-20µm——这将发射率从0.08(裸铝)提高到0.85,在自然对流条件下辐射冷却性能提升30%。如果您需要将1 260611223434a1用于户外或海洋环境,我们提供通过500小时盐雾测试的透明阳极氧化。

重复订单的包装和加工夹具设计

我们已经为1 260611223434a1制作了专用CNC夹具。这意味着您的重复订单无需重新设置时间——我们装载型材,从翅片侧夹紧,以零偏斜加工基座。夹具将型材保持在名义位置的0.01mm以内,因此不同批次之间的孔距保持一致。我们将每根型材用塑料薄膜套包装,然后放入带泡沫端盖的木箱中。对于100件以下的订单,我们使用防静电瓦楞纸箱。裸铝不会接触其他部件——您的装饰表面不会出现划痕。

定尺切割选项和定制修改

1 260611223434a1的标准长度为100mm、150mm、200mm、250mm和300mm。但我们可以在20mm至2000mm之间切割任意长度,切割公差为±0.2mm。如果您需要为悬垂组件做阶梯切割,我们可以铣削凹槽或台阶,厚度可薄至1.5mm。我们还钻侧孔用于热电偶接入——这是实验室验证的常见需求。只需发送标注修改的图纸;我们的工程师将在24小时内确认加工可行性。

与强制风冷和液冷冷板的兼容性

1 260611223434a1不仅限于风冷。3.2mm的基座厚度允许您直接在基座中加工蛇形通道用于液冷——我们使用4轴CNC铣床完成,通道深度公差保持在±0.05mm。翅片阵列随后可以切掉或保留作为辅助均热片。这种混合方法常见于激光二极管冷却,既需要低热阻(0.1°C/W),又希望保留一定的风冷作为备用。我们已为一家欧洲激光制造商完成了200多件此类改装。

原型与批量生产的价格和交期

对于1 260611223434a1,我们的原型服务(1-10件)价格为每件$8-15,具体取决于长度和加工工序。图纸确认后交期3天。对于批量生产(100-5000件),价格降至每件$3-7,因为减少了设置时间和批量挤压折扣。首批交期10天,后续批次7天。我们运营着一座20,000m²的工厂,拥有30台CNC机床和5条挤压生产线——我们绝不外包您的订单。所有工作均在厂内完成,这就是我们能以书面形式保证这些交期的原因。
