引言

您的TO-220晶体管运行温度过高。我们制造的散热器可解决这一问题。我们根据您的图纸进行机加工或冲压,验证每一个关键尺寸,并在检验合格后才发货。没有猜测,没有“差不多就行”。

概览: CNC加工特征公差±0.05 mm,图纸确认后标准交期7–12天,无起订量(可订10件或10,000件),每批次附带材质证书。

我们是一家位于中国东莞的精密制造工厂,拥有20年CNC加工、金属冲压、弹簧及散热器制造经验。您提供图纸,我们交付贴合、散热良好且通过贵方QC检验的零件。

定制圆形LED灯泡散热器

所有散热器在阳极氧化前均经过去毛刺和清洗处理。我们在翅片厚度和底面平整度上绝不偷工减料——您的晶体管需要完全接触才能有效传热。

采购商选择向我们发送图纸的三个理由

1. 批次可追溯质量。 每批次都有唯一批号。我们记录材料批次、机器参数和检验结果。如果您的产线上出现问题,我们可以追溯到具体的时间和操作人员。每次发货附带PDF报告——无需追查,没有含糊。

2. 每批次检验报告。 我们测量每批次的底面平整度、孔位、翅片间距和表面光洁度——而不仅仅是首件。您会收到包含实际数值的尺寸报告。对于关键尺寸,我们附上CMM数据。这是标准流程,不额外收费。

3. 一家工厂完成CNC + 冲压 + 弹簧 + 散热器。 您的装配可能需要冲压支架、弹簧卡扣和机加工散热器。我们全部在厂内完成。一个供应商、一个发货点、一个质量标准。您节省运费,避免不同供应商之间的公差不匹配问题。

这些零件的应用场景

TO-220晶体管散热器用于持续功耗1–5 W的电力电子设备。典型应用包括:

  • 开关电源——初级侧的MOSFET和稳压器。
  • 电机驱动器——变频器、伺服驱动器和无刷直流控制器。
  • 音频功放——AB类设计中的输出晶体管。
  • LED驱动器——需要稳定热管理的恒流稳压器。
  • 电池充电器——线性充电器和DC-DC转换器。
  • 工业控制柜——继电器驱动器和电压稳压器。

如果您的零件发热且采用TO-220封装,我们制造的散热器可确保其结温低于额定值。

采购商下单前常问的问题

问:你们真的没有起订量吗? 答:是的。我们接受从1件打样到100,000件量产的订单。打样单价较高,但您只需为所需数量付费。无需最低起订量即可开始合作。

问:你们如何保证公差和质量? 答:我们使用定位精度±0.005 mm的CNC机床。对于冲压件,我们将模具公差控制在±0.05 mm以内。每批次均附尺寸检验报告。如果零件超出规格,我们免费返工或重做——不向您收取任何费用。

问:定制散热器的交期是多久? 答:打样:图纸确认后5–7天。量产:7–12天,视数量和表面处理而定。对于紧急订单,我们可以分批发货——首批100件5天内发出,其余按周交付。

问:你们能提供材质证书吗? 答:可以。每批次均附带铝材或铜材的钢厂证书。我们还可按要求提供RoHS和REACH合规文件。材料可追溯性是我们标准流程的一部分,而非额外服务。

发送您的图纸

将您的TO-220散热器图纸发送给我们——PDF、STEP或IGES格式均可。我们将审核几何结构,如有需要提出制造改进建议,并在12个工作小时内返回正式报价。标准审核免费,无任何义务。
