<p>A motor case (24) in which a motor (22) for driving a fan (2) is housed is provided to a cabinet (3) in a dismountable manner, and the motor case (24) is in contact with and supported by the support member (45) of the cabinet (3). The hook (50) of the motor case (24) is engaged with a guide groove (51), and the motor case (24) is guided to one side in the axial direction while being supported by the support member (50). When the motor case (24) has been moved to an access space (S) located at a position separated from the fan (2), the hook (50) disengages from the guide groove (31) and the support by the support member (45) is lost. It becomes possible that the motor case (24) is mounted to and dismounted from the cabinet (2). As a consequence, the motor can be easily mounted and dismounted without removing a heat exchanger.</p> |
