ABSTRACT:
To improve soundproof performance on an air intake side of a cooling structure of a construction machine without enlarging an air intake chamber. An air intake chamber is provided on the air intake side of a heat exchanger in an engine room, and a first air intake port is formed in a top face of the air intake chamber. In the air intake chamber, a duct independently formed as a shield member is disposed so as to partition the air intake chamber into two chambers, and also such that the core surface of the heat exchanger is enclosed airtightly from the surrounding atmosphere. A second air intake port is formed in the duct; thereby, the air intake chamber is constituted in a doubled duct structure, and air sucked from the first air intake port is guided through an air intake passage to the core surface of the heat exchanger, the air intake passage being bent so as to be roughly L-shaped.
