  • In order to investigate effects of structural parameters of heat exchanger on fluid flow, heat transfer and overall performance in helical mini-channels with fan cavities, the helical mini-channels with different radiuses and pitches of fan cavities were designed in present work. The fluid flow, heat transfer and overall performance characteristics in these mini-channels under different Re were studied using numerical simulation. The results showed that the fan cavities had obvious influences on the fluid flow performance in the helical mini-channel. At the range of 168<Re<2016, the flow resistance increased with the increase in the radius of fan cavity. The flow resistance descreased with the rise in the pitch of fan cavity when Re>336. But this trend was inversed when Re<336. The variations for structural parameters of fan cavity had no significant influence on heat transfer performance. Also these variations can't improved obviously the overall performance in helical mini-channel.The helical mini-channels with fan cavities were suitable for the low ranges of Re.
