Title
(EN) COOLING STRUCTURE OF CONSTRUCTION MACHINE
Abstract
(EN) To improve a soundproof performance on an air intake side of a cooling structure of a construction machine without enlarging an air intake chamber.Solution: An air intake chamber (16) is provided on the air intake side of a heat exchanger (15) in an engine room (12), and a first air intake port (17) is formed in a top face of the air intake chamber (16). In the air intake chamber (16), a duct (18) independently formed as a shield member is disposed so as to partition the air intake chamber (16) into two chambers (16a), (16b), and also in a manner such that the core surface (15a) of the heat exchanger (15) is enclosed airtightly from the surrounding atmosphere. A second air intake port (24) is formed in the duct (18); thereby, the air intake chamber (16) is constituted in a doubled duct structure, and air sucked from the first air intake port (17) is guided through an air intake passage to the core surface (15a) of the heat exchanger (15), the air intake passage being bent so as to be roughly L-shaped.
