Abstract (en)
The title of the invention is a heat exchanger and a refrigeration cycle apparatus including the heat exchanger. A first pipe has an inflow port for a heat medium and an outflow port for the heat medium, the inflow port and the outflow port communicate with a first flow path. The first pipe includes a crest portion, which protrudes in a diameter-increasing direction in which a diameter of the first pipe is increased, and a trough portion having an outer diameter smaller than that of a part in which the crest portion is formed, and a second pipe is wound around the trough portion. The crest portion is formed in a helical shape in the first flow path in a direction in which the heat medium flows. The trough portion is formed in a helical shape along the crest portion. The trough portion includes a plurality of concave portions, which are formed so as to be aligned with each other in a helical direction that is a direction in which the trough portion is formed, and are recessed in a diameter-decreasing direction in which the diameter of the first pipe is increased.
