<P>PROBLEM TO BE SOLVED: To improve air flow performance and raise suction efficiency up by disposing an air cleaner in an intake chamber. <P>SOLUTION: A first air inlet 14 is disposed on a top wall of the inlet chamber 9 disposed at the air-inlet side of a heat exchanger 7 in an engine room 4, while a duct 19 having a second air inlet 15 for introducing air into a core surface 7a of the heat exchanger is disposed at the air inlet side of the core surface 7a of the heat exchanger. On the assumption of the foregoing, the cooling structure of a construction machine has such a configuration that: the air cleaner 16 is disposed at the position which is below a straight line L for connecting an outer end most distant from the duct 19 in the first air inlet 14 and a lower end of the second air inlet 15 and which is near the straight line L in the air entrance side of the duct 19; and an air flow Fo of an outer edge side is guided to the second air inlet 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
