产品详情

这是一款挤压铝散热器,配有预装弹簧夹,适用于通孔或表面贴装功率器件。我们使用五轴CNC加工中心进行加工,确保翅片间距保持在±0.05 mm,基座平面度每100 mm控制在0.02 mm以内。弹簧夹采用65Mn钢制成,热处理至45–48 HRC,在10,000次循环中提供18–22 N的稳定夹紧力。标准尺寸交期为15天,该产品线支持无起订量

弹簧夹如何以18 N力固定IGBT和MOSFET

该夹片并非普通弯曲钢丝。我们使用0.6 mm厚的65Mn弹簧钢冲压成型,然后经过油淬和回火处理至45–48 HRC。每个夹片在2吨压力机下预装到散热器槽内,确保接触点精确落在器件中心线上。实测夹紧力:18–22 N,重复精度±1 N。这可以防止热循环过程中的微振动,而微振动是导热硅脂泵出效应的主要原因。每批产品发货前,我们使用5,000次推拉循环夹具测试夹片保持力。

挤压型材限制:可保持的翅片间距、高度和基座厚度

我们的2,000吨挤压机可生产宽度达300 mm的型材。对于此散热器,我们将翅片间距控制在4.0 mm或6.0 mm,翅片高度15至60 mm,基座厚度3至10 mm。直线度通过拉伸矫直机校正至每米0.5 mm。挤压后,我们通过CNC加工安装孔、沉孔和夹片槽。孔位公差为±0.05 mm,我们使用三坐标测量机验证首件及每第50件产品。

表面光洁度Ra 0.8:为何默认不阳极氧化,除非您要求

标准表面处理为光亮浸渍和透明阳极氧化(Ra 0.8 µm),以提高耐腐蚀性。如果您的应用需要最大热接触性能,我们可以跳过阳极氧化,将基座加工至Ra 0.4 µm。阳极氧化层的导热系数低于裸铝,因此对于高热密度设计,我们推荐使用带微蚀表面的裸AL6063-T5。我们使用泰勒霍普森表面轮廓仪对每批产品进行表面粗糙度记录——而不仅仅是抽样检测。

夹片和挤压件使用的材料及热处理工艺

挤压件:AL6063-T5或AL6061-T6。6063-T5因其导热系数(201 W/m·K)和挤压性能而成为标准选择。当您需要在振动剧烈环境中获得更高机械强度(屈服强度240 MPa)时,使用6061-T6。夹片:65Mn弹簧钢,45–48 HRC。如需耐腐蚀性能,我们可替换为SUS301不锈钢,回火至40–45 HRC。我们绝不使用无钢厂证书的再生铝——每根铝棒均可追溯至冶炼厂。

每次发货前的检验:三坐标测量、拉力测试和表面轮廓仪

每个散热器均经过三项检查。首先,三坐标测量机测量孔位和基座平面度(0.02 mm)。其次,夹片拉力测试使用数字测力计验证18 N的力。第三,表面轮廓仪检查Ra值。我们还进行100%目视检查,检查划痕、凹痕和阳极氧化缺陷。对于500件以上的订单,我们随货附上由QC工程师签字的尺寸报告。我们遵循ISO 9001:2015标准,如您的客户要求,可提供PPAP Level 3。

包装、防静电保护及打样与量产交期

打样(1–10件)通过DHL快递5天内发货,使用ESD泡沫和防静电袋包装。量产(100–10,000件)15天内发货,使用带泡沫内衬的分隔纸箱包装,防止翅片弯曲。每箱装50件,纸箱上标注零件号、批次代码和RoHS合规标签。我们不使用松散填充物——每个散热器均单独套袋,防止表面磨损。

如何为非标准器件高度修改夹片

标准夹片高度为10 mm,专为TO-247和TO-220封装设计。如果您使用不同器件,请将封装图纸发送给我们,我们将调整夹片折弯角度和槽深。我们有12套标准夹片模具,定制模具费用为$400–$800,交期7天。对于大批量订单,定制模具费用将分摊到单价中。我们还可以在夹片上增加肩台,以适配宽度达62 mm的IGBT模块等较大器件。

热性能数据:50 W和100 W负载下的预期表现

在50 W负载下,翅片间距4.0 mm、翅片高度30 mm时,热阻为1.1 °C/W(自然对流,环境温度25 °C)。在100 W负载下,由于边界层效应,热阻升至1.8 °C/W。若增加2 m/s的强制风冷,热阻降至0.4 °C/W。对于500件以上订单,我们免费提供热仿真(Fluent)。这些数据为实测值而非仿真值——我们使用带加热模具的风洞进行验证。

为何我们是精密制造合作伙伴,而非普通供应商

我们在东莞拥有20年历史,具备内部模具、冲压和CNC能力——全部自主完成,无外包。这就是精密制造中国制造的全流程管控。我们拥有40台CNC机床、15台冲压机和2条挤压生产线。您只需一个对接窗口即可完成挤压、夹片和最终组装。我们的准时交付率稳定在99.2%,并保持3,000件标准散热器的安全库存,支持当日样品发货。
