PURPOSE:To obtain a heat exchanging device, capable of reducing the installation area of the same, by a method wherein the heat exchanging device is provided with a structure, through which an air passage can be provided between the device and a wall surface easily. CONSTITUTION:A heat exchanger 2 is arranged with an angle alpha of inclination so as to be arranged in parallel substantially to the angle beta of inclination of the blade of an axial-flow fan 3 having sweepforward or sweepback blades 3a. According to this method, an air passage, expanding gradually toward the outside lateral direction between a wall surface 6 behind the heat exchanger 2, can be taken whereby a gap L between the wall surface 6 can be reduced. |
