| 摘要 |
The invention discloses a construction machinery used for removing the dust from the heat radiator and other heat exchanger. The construction machinery is provided with heat exchangers (24). The refrigerant flowing in the plurality of heat exchangers (24A-24E) can be cooled by the cooling wind (39). A dustproof device (40) is provided with a pair of carrying racks (41A,41B) disposed on the frame (25) by being separated by the heat exchangers (24). An upper dustproof mesh (51) and a lower dustproof mesh (52) are detachably disposed on the carrying racks (41A,41B). The dustproof device (40) is disposed on the upstream side of the heat exchangers (24) with respect to the flowing direction of the cooling wind (39). |
