摘要： In an engine intake structure for a construction machine, to prevent suction of hot exhaust gasses or heated cooling air without disturbing the maintenance/inspection work, intake ports 30a, 30b are provided in a hingeable door 19 located in a side panel 6c of a machine compartment 6. An intake duct 31 made of elastic material such as rubber is extended from an air cleaner 13 to a position near the intake ports 30a, 30b, and a joint duct 32 for operatively connecting the intake ports 30a, 30b with the intake duct 31 when the door 19 is closed is attached to the inner side of the door 19 by welding or the like. The intake ports 30a, 30b are formed as two horizontally extending, elongate apertures in order to ensure a sufficient inlet area. The joint duct 32 comprises a box-shaped portion 32a and a tapered tubular portion 32b. The box-shaped portion 32a of the joint duct 32 has a bottom wall inclined downwardly to smoothly connect with a bottom surface of the lower intake port 30b so that rainwater eventually entered into the joint duct 32 is drained through the lower intake port 30b. When the door 19 is closed, a distal end of the tubular portion 32b of the joint duct 32 comes into close contact with the intake duct 31 preventing noise from spreading to the environment.

摘要： In a cooling structure for a construction machine, to minimize the occurrence of a turbulent flow of air, provide a better cooling ability, and reduce noise pollution, a recess 20 is formed in a portion of an engine cover 6d above a front portion of an engine 8, and exhaust ports 15a are provided in an inclined portion of the recess 20 facing a fan 9. A space "A" having a proper size is thereby delimited by a portion 21 of the engine cover 6d, which is positioned radially outwardly of the fan 9, the exhaust ports 15a and the fan 9. Said portion of the engine cover 6d forms a first guide 21 for guiding part of the cooling air which has passed the fan 9, in a laminar flow, to the exhaust ports 15a. The opposite slope of the recess 20 forms a second guide 22 for guiding the cooling air discharged through the exhaust ports 15a in a laminar flow to the environment. A distal end 22a of the second guide 22 is positioned at a lower level than a distal end 21a of the first guide 21, and the exhaust ports 15a extend between said distal ends 21a and 22a.

摘要： In a cooling structure for a construction machine, a condenser (50) of an air conditioning system is installed in a machine compartment (6) in a manner whereby a superior cooling ability for a radiator (11) and a oil cooler (10) is obtained, while cooling the condenser (50). Ambient air is sucked in by a fan (9) through intake ports 14a, 14b and 14c, successively cooling the condenser (50), the oil cooler (10) and the radiator (11), whereafter it is discharged to the environment through exhaust ports (15a, 15b, 15d, 15e). The oil cooler (10) is erected parallel to the radiator (11), while the condenser (50) is inclined so as to extend from an area near a lower end of the uppermost intake port (14b) formed in a side wall of an engine cover (6d) towards a bottom end of the oil cooler (10).
