产品详情

挤压铝散热器系列02包含12种标准型材,专为IGBT模块、电源和LED驱动器的强制风冷和自然对流冷却而设计。每种型材的平面度公差为每100毫米长度0.05毫米,表面光洁度为Ra 1.6 µm,因此您可以直接安装组件,无需研磨或补偿导热垫厚度。

这些散热器是BQUQ在中国制造的精密制造产品,BQUQ是一家拥有20年历史的工厂,专注于CNC加工、冲压和弹簧制造。标准型材的交期为订单确认后15天,我们还提供60 HRC硬质阳极氧化选项,适用于磨损性环境。

匹配实际气流的型材几何形状和翅片间距

系列02涵盖翅片高度15毫米至45毫米、基板厚度4毫米至10毫米,以及5毫米、7毫米和10毫米的翅片间距。5毫米间距型材专为高静压风扇设计;10毫米间距型材适用于自然对流或低速轴流风扇。

所有型材均采用6063-T5铝挤压成型,导热系数为209 W/m·K。我们将挤压模具公差控制在翅片厚度±0.1毫米、总宽度±0.15毫米。这意味着您无需自行运行CFD即可预测热阻,误差在±5%以内。

CNC精加工:一次装夹完成切割长度、孔和螺纹

原始挤压只是起点。系列02中的每个散热器均按您指定的长度切割,锯切公差为±0.2毫米,然后根据需要在3轴CNC加工中心上进行加工,包括安装孔、攻丝螺纹或沉孔。我们将孔位公差控制在0.05毫米,螺纹深度公差控制在±0.3毫米。

如果您不确定这些铝挤压件的刀具几何形状,请在最终确定图纸前查阅我们的CNC切割刀具选择指南。关于孔间公差和基准公差,我们的CNC加工公差指南详细说明了我们能在不增加成本的情况下达到的公差范围。

硬质阳极氧化最高可达60 HRC,适用于磨损性安装环境

标准表面处理为透明阳极氧化,符合MIL-A-8625 Type II标准,厚度10–15 µm。如果您的装配过程涉及反复支架滑动或与钢制零件振动接触,我们仅在基板表面施加Type III硬质阳极氧化,硬度为40–60 HRC。这不会显著降低热性能;涂层增加的热阻小于0.05 °C/W。

我们还提供铬酸盐转化涂层(Alodine),适用于电气接地要求。除非特别指定,螺纹孔内不施加涂层,因为我们在阳极氧化后会重新攻丝,以恢复2B级螺纹精度。

按需切割长度,无最小起订量,标准交期15天

您可以订购一件或一千件。无最小起订量政策适用于系列02中的每种型材。标准交期为:仅切割长度15天,CNC孔和螺纹18天,如需硬质阳极氧化则为21天。对于紧急订单,我们可以从库存中提取型材并在7天内发货。

所有型材均以3米棒材形式存放在我们东莞的仓库中。我们按您的精确长度切割,去除所有边缘毛刺,并在包装前清洁零件,使用泡沫隔板防止运输过程中翅片损坏。

每次发货前均进行检验报告和尺寸检查

每批产品,无论数量多少,均进行全面检验。我们使用花岗岩平台和千分表测量平面度,用卡尺检查翅片高度,50件以上订单使用三坐标测量机验证孔位,并使用轮廓仪记录基板表面粗糙度。

您将收到包含实际测量值的PDF检验报告,而不仅仅是合格/不合格标记。对于200件以上的订单,如果在报价阶段提出要求,我们会提供关键尺寸的工序能力指数(Cpk)。

如何从系列02中选择合适的型材

如果您的热源小于基板面积的40%,请选择基板较厚(8毫米或10毫米)的型材,以便在热量到达翅片前充分扩散。如果气流受限,请选择10毫米翅片间距以降低压降。如果您使用功率较高的IGBT且强制风速超过3 m/s,则5毫米间距型材将提供每单位长度的最低热阻。

我们还可以修改任何型材,例如移除安装孔附近的翅片或在基板上增加台阶。这是一项快速的CNC操作,不会将交期延长至18天以上。

保护长零件翅片的包装和运输

长度超过300毫米的零件采用硬纸箱包装,内衬与翅片轮廓匹配的泡沫通道。我们不使用松散的气泡膜,因为它在运输过程中可能弯曲薄翅片。对于国际空运,20公斤以上订单使用木箱。对于海运,我们使用带干燥剂的防潮袋。

每个箱子均贴有型材编号、长度、数量和您的采购订单号。如果需要,我们可以根据您的仓库系统要求添加自定义标签或条形码。

成本驱动因素及如何降低单价

系列02的基础价格由挤压重量和切割长度决定。CNC孔加工按批次收取固定设置费用,而非按孔计费。硬质阳极氧化使单价增加约8%。如果您每月订购相同型材和长度,我们可以为您保留缓冲库存并在5天内发货,同时单价还可降低3%。

如需快速价格估算,请发送您的长度、孔位布局和年需求量。我们将在12小时内回复固定报价,包括新挤压模具的模具费用(如有)。

标准型材列表及预期应用

型材02-01至02-04为低矮型(翅片高度15–20毫米),适用于LED驱动器和DC-DC转换器。型材02-05至02-08为中高型(25–30毫米),适用于MOSFET桥和伺服驱动器。型材02-09至02-12为高型(35–45毫米),基板较厚,适用于IGBT模块和大功率整流器。

所有型材均可在基板上选择安装槽选项(宽3毫米,深6毫米),用于弹簧夹。如果您使用导热胶而非螺钉,我们可以提供铣削平面,表面粗糙度Ra 0.8 µm,以获得更好的接触效果。

挤压铝散热器系列02的最小起订量是多少?

没有最小起订量——您可以订购单件切割长度用于原型制作,或订购整批生产数量。

您能定制这些散热器的孔位布局或翅片长度吗?

可以,任何型材均可通过CNC加工定制孔、螺纹、沉孔或台阶切割,我们将位置公差控制在0.05毫米。

您如何控制小批量订单的质量?

每批产品,即使只有一件,都会进行全面的尺寸检验,您将收到包含平面度、长度和孔位实际测量值的PDF报告。

如果需要硬质阳极氧化,实际交期是多久?

标准交期为:仅切割长度15天,CNC加工18天,如需Type III硬质阳极氧化则为21天。
