摘要: Abstract In this study, the effectiveness of plain fin-and-tube heat exchangers constructed using anisotropic, micro-patterned aluminum fins has been explored. These which can more completely drain condensate that forms on transfer surface during normal operation were selected with aim improving thermal-hydraulic performance exchanger. This study presents and critically evaluates efficacy four full-scale by measuring comparing dry/wet air-side pressure drop data. The prototype fin surfaces shown to reduce wet from 9.3% 53%, while at same time having a negligible effect sensible coefficient under both dry conditions. That is say, novel design ability, through improved management, enhance Data pertaining durability alkyl silane coating used in work are also presented.
