PROBLEM TO BE SOLVED: To improve fitting workability of a dustproof net by accurately guiding a lower end of the dustproof net toward a net receiving frame when inserting and fitting the dustproof net from the upper side of the net receiving frame.SOLUTION: A rear partition cover 19 is arranged in an inclined manner so that the outer end side thereof faces a front side more than the inner end thereof. A net receiving frame 16 is provided on an inflow side of cooling air flowing into a heat exchanger 11 and on a lower side of a support frame body 12 of the heat exchanger 11. A dustproof net 17 is provided at a position facing the inflow side of cooling air flowing into the heat exchanger 11. Thereon, a dustproof net guide 20 vertically extending in a position corresponding to the rear end of the net receiving frame 16 and guiding the dustproof net 17 to the net receiving frame 16 is provided in the rear partition cover 19. Thereby, a lower end 17D of the dustproof net 17 can be guided toward the net receiving frame 16 while a rear end 17B of the dustproof net 17 is positioned along the dustproof net guide 20. |
