A heat exchanger (1) is adapted to be used in a vapor compression system, and includes a shell (10), a distributing part (20) and a tube bundle (30). The tube bundle (30) includes a plurality of heat transfer tubes (31) arranged in a plurality of columns extending parallel to each other when viewed along the longitudinal center axis of the shell (10). The heat transfer tubes (31) has at least one of: an arrangement in which a vertical pitch between adjacent ones of the heat transfer tubes (31) in at least one of the columns is larger in an upper region of the tube bundle (30) than in a lower region of the tube bundle (30); and an arrangement in which a horizontal pitch between adjacent ones of the columns is larger in an outer region of the tube bundle (30) than in an inner region of the tube bundle (30). |
