LC-L5G 具有高输出,采用专有的风冷方法。传统 UV-LED 光源无法实现高通量,但 LC-L5G 可以。
专利型空气制冷法 ThoMaS (*1) 由三个要素组成:“热观察”、“Sylphy Air”和“材料”。
*1:ThoMaS 仅适用于 GH-103A 型号。
“热观察”是一种用于高效制冷 UV-LED 光源的热分析技术。
通过将模拟与实际设备评估相结合,我们获得了对加热值的了解。基于速度矢量和温度分布,在短时间内就气流在预期目标上的“循环”、“定向”和“接触”方式实现优化。
滨松的工程师凭借热分析方面的专业知识,不断致力于追求高性能制冷机理。
“Sylphy Air”是滨松正在申请专利的专利型制冷结构。
优化了进气口、散热器、风道和制冷风扇在专用设计中的布置,将制冷性能水平提高到极致,而制冷性能正是提高光输出的关键。
通过产品侧面的进气口吸入空气,然后将其送入散热器。
在散热器内安装空气导流翅片会在散热器内产生气流,继而改善制冷性能。
将新型散热器的性能与传统散热器在其速度矢量和温度分布方面的性能进行比较,表明气流能够更有效地接触新散热器的基材表面,从而实现更好的制冷。
穿过散热器的气流通过位于产品中心的排气管,从产品顶部的制冷风扇排出。
排气管采用双壁绝缘结构。排气管的所有侧面都被制冷空气包围,因此不与外壳接触。这种布置可防止外壳温度升高。当采用菊花链运行两个或多个光源单元时,这种双壁绝缘结构有助于抑制外壳之间因相互影响而出现的温升,以消除对照射分布特性的不利影响,并减少 UV-LED 光源本身的热负载。
“材料”是由滨松开发的一种独特的制冷材料。
这种新型散热器“Sylphy air”具有前所未有的高制冷性能,体积为 795 cm3,重量为 1060 g。
滨松力争进一步缩小尺寸并改善性能,并已开始开发采用专利型制冷材料的下一代散热器,计划将该散热器尺寸缩小一半,重量缩小三分之二,但在未来仍能提供与新型散热器相同的制冷性能。下一代散热器的这一进步将导致 UV-LED 光源的尺寸大幅减小,在提供相同性能水平的同时实现体积减半。此外,如果保持相同尺寸,UV-LED 光源可能会具有更高的性能和更广的用途。
