Title: (ZH) 带螺旋纽带的片式散热器
Abstract: front page image
(ZH) 一种带螺旋纽带的片式散热器,包括进油管、回油管及一组散热片,一组散热片各由前、后散热板片组成,前、后散热片之间的上部区域构为散热片进油腔,下部区域构为散热片回油腔,中部区域构为散热油道,散热片进油腔与进油管相通,散热片回油腔与回油管相通,散热油道内设螺旋纽带,特点:螺旋纽带设在散热油道的上部或中部,且该螺旋纽带的长度与散热油道的高度之比为3.5‑4.5∶100。可使油液产生二次流,促使油液充分混合,及破坏油液的热边界层而得以增大传热系数,避免增大油液的流阻,确保散热效率;减小散热器的规格尺寸以及减少散热器在油浸式变压器上的配置组数,降低成本及增进对安装空间的适应程度。
