Abstract:
A fin-and-tube heat exchanger comprises: fins (31) which each have flat sections (35), first sloped sections (36), and second sloped sections (38); and heat transfer pipes (21). If a flat plane which is in contact, from the side opposite the crest of a ridge (34), with the upstream end and downstream end of the first sloped sections (36) in the air flow direction is a reference flat plane (H1), the angle between the reference flat plane (H1) and each of the second sloped sections (38) measured in a region upstream of a through-hole in the air flow direction is θ2, then the range of θ2 is determined by the relationship 0°
