按设备类型选择散热风扇

风扇好不好,取决于它和机箱是否匹配。对 350kW 充电桩机柜正确的答案,放到球机护罩上就是错的——哪怕两者风量数字相同。这一节按设备类型拆解:每类设备真正决定选型的是什么、常用什么尺寸、以及对应的型号页。

云帆能量科技自 2005 年在深圳制造散热风扇:20–280mm 直流无刷轴流风扇、80–280mm 交流轴流风扇、EC 节能风扇与 40–120mm 直流鼓风机。下面这些设备类型,是我们每天都在供货的场景。

按设备找到合适的风扇

设备类型选型关键常用尺寸选型指南
UPS 与开关电源连续运行,排风 45–60℃60–172mmUPS 与电源
CCTV 与安防护罩密闭小空间,防雨防尘25–80mmCCTV 安防
充电桩滤网与百叶压降、IP68、PWM92–280mm充电桩
LED 舞台灯狭窄风道、70℃ 气温、噪音红线40–97mmLED 舞台灯
通信机柜过滤强制风冷,十五年寿命目标92–280mm通信机柜
医疗器械低噪音、低振动、转速稳定25–92mm医疗器械
3D 打印机24V 母线,风道送风30–50mm3D 打印机
电焊机粉尘与金属颗粒,60–70℃92–280mm电焊机

为什么我们从应用出发,而不是从型号出发

两个外框都是 120×120×38mm 的风扇,静压可能相差三倍,60℃ 下的轴承寿命可能相差十倍。只对型号,会买到「参数对、装上不好用」的产品。我们更愿意先问四件事:

  • 工作点—— 在你的机箱实际阻力下能给出多少风量,而不是样本上的自由风量。
  • 进风温度—— 在风扇位置、设备运行一小时后测得,而不是规格书上的室温。
  • 工作制与寿命—— 每天运行小时数与质保所依据的 L10 寿命,它决定选含油、液压还是双滚珠轴承。
  • 接口—— 电压与容差、端子、线长,以及主控是否需要 FG 测速或 RD 停转反馈。

这些页面共同说明的几件事

  • 列出的型号都是已有模具的机型——图示尺寸不额外收取开模费。
  • 电压、轴承、端子、线长与防护等级都可在同一机座上配置。
  • 可提供 CE 与 RoHS 声明,以及所供型号的 SGS 检测报告。
  • 工程验证样品与量产分开报价,你可以先测试再决定。

把设备类型、可用空间和风扇进风处的环境温度告诉我们,我们会回复两到三个方案,并说明各自的取舍理由。获取选型建议或了解我们的OEM / ODM 定制服务如何运作。
