【应用】Nidec在超薄PC专用的风扇马达中使用液压轴承技术,实现小型化、轻量化设计,有效解决风量和噪音问题
日本电产将硬盘驱动器主轴马达研发过程中积累下来的FDB(液压轴承)技术应用于风扇马达,致力于研发更加小型化、超薄化的风扇马达。
将在硬盘驱动器方面拥有众多实例的FDB(液压轴承)适用于风扇马达
由于服务器的风扇振动会给硬盘驱动器的存储和读取带来影响,于是顾客纷纷提出要求希望解决此问题。因硬盘驱动器的高密度化使外部振动容易受到影响,另一方面,作为解决CPU超频发热的对策,服务器专用的高转速风扇在不断进化,转速高达20,000rpml的强风量风扇马达也面世了。日本电产用FDB(液压轴承)代替了曾是主打产品的滚珠轴承,因此迅速解决了硬盘驱动器用主轴马达的振动问题。于是,诞生了把FDB充分运用在风扇马达轴承上的想法,在这种创想的指引下,风扇马达轴承的FDB化得到了推进。
近年来,超薄PC的高性能化得到不断发展,搭载的CPU也在向高频驱动转变,但是CPU产生热量的排散却成为一个大问题。同时,噪音也成为关注的焦点,人们对低噪音风扇马达的的需求逐渐增多。FDB(液压轴承)在硬盘驱动器用的主轴马达方面拥有众多佳绩,因此日本电产将其应用在了风扇马达中并作为UFF(UltraFlo FDB)系列推向了市场。但是超薄PC的轴承市场竞争非常激烈,为了提高竞争力,对此风扇马达的性能进行了改良。渗透到磁路、金属部件的树脂化、轴径等用硬盘驱动器构筑的结构,从风扇马达的视角进行了全方位改善。
全面改善马达构造,使风扇马达适合化。进而实现更具强大竞争力的马达构造。
充分利用超级计算机的计算机辅助工程以解决风量、噪音等问题
风量及噪音问题的解决是与FDB(液压轴承)和磁路的风扇马达的适合化同时推进的。一般来说,风扇马达使风量增大的话,噪音比例也随之增大。不仅是办公室,一般家庭也在普遍追求笔记本PC的静音化。
因此,在利用计算机辅助工程技术确保指定的风量的同时,也挑战了为探索可实现低噪音的风扇叶片的尺寸和形状的设计方案。于是构建了可整合分析风量和噪音的耦合分析技术。解析“风扇—经由路线—冷却对象”这一过程的空气流动和噪音的相关性,并将其充分运用在设计中,从而找出合适的叶片规格。不仅要降低噪音带来的总耗能量,还要击破特定频带的峰值,通过转换成适合人类听觉的音色,从而实现静音化。
利用耦合分析技术对风量和噪音进行整合分析,以确立一种可确保指定的风量并可以降低噪音的设计方案。

【经验】浅析如何选择合适的散热风扇
散热有三种方式:对流、传导和辐射。在大气环境中,对流又分强制对流和自然对流。强制对流一般首选风扇进行吹风或抽风式风冷散热。风扇其实是个组件,包括马达、扇叶、导线、连接器,控制PCB等。那么该如何选择风扇呢?本文中笔者将给出一般经验供参考。
