Title: (EN) Take gilled radiator of spiral tie
(ZH) 带螺旋纽带的片式散热器
Abstract: front page image
(EN) The utility model provides a take gilled radiator of spiral tie, includes into oil pipe, returns oil pipe and a set of fin, each comprises a set of fin preceding, rear radiating plate piece, upper portion between preceding, the rear radiating plate piece is regional constructs for fin oil feed chamber, lower region constructs for fin oil return chamber, the middle part is regional constructs for the heat dissipation oil duct, fin oil feed chamber with advance oil pipe and communicate with each other, fin oil return chamber communicates with each other with returning oil pipe, establishes spiral tie, characteristics in the oil duct that dispels the heat: is the spiral tie established at the upper portion or the middle part of heat dissipation oil duct, and the comparing for 3.5 of the height of the length of this spiral tie and heat dissipation oil duct 4.5: 100. Can make fluid produce the secondary flow, make the fluid intensive mixing, and destroy the thermal boundary layer of fluid and can increase coefficient of heat transfer, avoid increasing the flow resistance of fluid, ensure the radiating efficiency, reduce the specification and dimension of radiator and reduce the configuration group number of radiator on oil -immersed transformer, reduce cost and the adaptedness of enhancement to installation space.
(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、后散热板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。
