Abstract
A heat exchanger includes a plurality of heat transfer tubes, a liquid header distributor, and a gas header distributor. The heat transfer tubes include U-shaped bent portions. The heat exchanger includes a heat exchanger core. A relationship between the liquid header distributor and the plurality of heat transfer tubes is established such that 9≤ζ is satisfied, where Lh [m] is the length of the liquid header distributor, Lb [m] is the length of the shortest one of the heat transfer tubes, and ζ is the ratio of the length Lb of the shortest heat transfer tube to the length Lh of the liquid header distributor and is expressed by ζ=Lb/Lh.
