5G基站热管理的最新趋势是什么?
5G基站热管理的最新趋势是什么?

最直接的答案是,5G基站热管理正从被动式铝挤压散热器转向混合主动-被动系统、液冷和相变材料,其驱动力在于相比4G,功率密度提升了3倍。现代5G远端射频单元(RRU)每个单元产生300W至1000W的热量,需要结温保持在85°C以下,以确保15年的使用寿命。行业正在标准化采用压铸铝或铜热管结合强制风冷,同时探索用于大规模...

2026年全球散热器市场规模是多少?驱动因素有哪些?
2026年全球散热器市场规模是多少?驱动因素有哪些?

全球散热器市场预计到2026年将达到约89亿美元,2024年至2026年复合年增长率(CAGR)为6.2%。这一增长主要由三大领域驱动:需要高性能液冷的人工智能(AI)数据中心、需要高效电池热管理的电动汽车(EV),以及需要为高密度射频组件提供被动散热的5G/6G电信基础设施。对于采购工程师而言,这意味着交货周期更紧、...

均温板、热管与铲齿散热片的技术路线图是什么?
均温板、热管与铲齿散热片的技术路线图是什么?

均温板 vs 热管 vs 铲齿散热片技术路线图问题的直接答案是什么?技术路线图很清晰:铲齿散热片仍然是热通量低于150 W/cm²的风冷设计中成本最低的解决方案,热管在50 W至250 W范围内主导对成本敏感的远程热传输,而均温板则是高于200 W/cm²的高热通量、空间受限电子设备以及大型处理器芯片均热场景的必然选择...

AI服务器液冷应用如何影响散热器设计?
AI服务器液冷应用如何影响散热器设计?

AI服务器液冷的快速普及正在从根本上改变散热器的设计,从大型翅片式铝挤型材转向紧凑、高密度的铜制微通道和冷板结构。虽然风冷对于350W以下的处理器仍然可行,但热设计功耗(TDP)超过700W的AI GPU现在需要液冷,这促使散热器体积减少40%至60%,但制造成本和复杂性却增加了200%。这一转变直接影响了像BQUQ这...

边缘AI热管理的最佳紧凑型冷却解决方案有哪些?
边缘AI热管理的最佳紧凑型冷却解决方案有哪些?

针对分布式AI系统,最有效的紧凑型散热解决方案是将高密度散热片与强制对流相结合,使用微型鼓风机或合成射流,以在小于10升的机箱内管理5至25 W/cm²的热通量。对于大多数边缘部署,混合方案——铝或铜均温板底座,搭配15至30毫米高的鳍片堆和40毫米x 40毫米的鼓风机——能在热性能(外壳至环境热阻0.5至2.0 °C...
