PURPOSE:To facilitate the maintenance of a lateral flow fan by inserting a rod-shaped supporter (driver) of a heat exchanger into a boss hole provided through a flange of the heat exchanger and holding the supporter by a holding hole. CONSTITUTION:In a heat exchanger 6, a boss hole 13 is loosely engaged with a boss 12 and a flange 6a is contacted with the end surface of a holding part 11a to fix the flange by a fastener. During maintenance, the end of a driver 14 is inserted deeply into a holding hole 12a provided on a boss 12, following which, after the fastener is removed, one side of the exchanger 6 is pulled in a direction of arrow (a). At this moment, the boss hole 13 comes into engagement with the axis 14a of the driver 14 and hence it is not necessary to support the exchanger 6 by hand and the exchanger 6 is guided approximately horizontally, so that it can be positioned at any location. Next, a lateral flow fan 7 is pulled in a direction of arrow (b) and then it can be drawn out from between the exchanger 6 and a rear side case 12. In this manner, the maintenance of the fan 7 can be easily performed. |
