Abstract
A heat exchanging device includes a frame member assembled having a square frame shape by using a lower frame extending in a front and rear direction and mounted on a revolving frame, side frames extending to an upper side from both ends of the lower frame, and an upper frame extending on an upper part of the side frames. A cooling fan is disposed in a state in which each of the blades enters into the frame member from an engine side end surface with respect to the frame member. An oil cooler and a radiator are mounted on a mounting surface plate on an opposite side to the engine and interposing said cooling fan at an interval from the cooling fan with respect to the frame member. A flat plate shaped shroud surrounding each of the blades of the cooling fan and forming a fan accommodating chamber among the frame member, the oil cooler, and the radiator is mounted on the engine side end surface of the frame member.
