An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2. Reference numeral 1 denotes a cooling fan driven by an engine of a hydraulic power shovel (not shown), and the left side of the cooling fan in FIG. That is, an engine cooling water radiator 2 is disposed on the upstream side of the cooling air, and the radiator 2 is fixed to a radiator frame 4 having a U-shaped cross section and fixed to the main body of a hydraulic power shovel (not shown) via a substrate 3. has been done. Further, on the upstream side of the radiator 2, a hydraulic oil cooler 5 for cooling the hydraulic oil is disposed with a small gap from the left end of the radiator frame 4 in FIG. Bolt 7 to radiator frame 4
Fixed by A substrate 3 is provided between the radiator 2 and the hydraulic oil cooler 5 so that the cooling air that has passed through the hydraulic oil cooler passes through the radiator 2.
A cooling air passage 9 is provided by a shroud 8 consisting of a cooling air passage 9 and two radiator frames 4, and the upper part of the shroud 8 in FIG. Furthermore, a lid 11 is disposed in the opening 10 and is configured to open and close the opening. The lid 11 is pivotally supported on the radiator frame 4 via a shaft 12, and further fixed to a stopper plate 13 fixed to the radiator frame 4 with bolts 14. According to the above configuration, even if the distance between the radiator 2 and the hydraulic oil cooler 5 is made larger than before, the amount of cooling air passing through the radiator 2 will not decrease because the cooling air passage 9 is provided by the shroud 8. In addition, an upwardly directed opening 10 is formed in the upper part of the shroud 8, and the opening 10 is configured to be able to be opened and closed by a lid 11, so that if dust or the like adheres to the front surface of the radiator 2, the bolt 1
4 is removed, the lid 11 is opened, and dirt and the like adhering to the front surface of the radiator 2 can be easily cleaned from the opening 10. Therefore, in the past, the radiator 2 and the hydraulic oil cooler 5 were disposed close to each other, which caused problems such as overheating due to difficulty in cleaning dust etc. adhering to the front surface of the radiator 2. However, the present invention has been improved. Accordingly, the above-mentioned conventional problems are improved.

and two radiator frames 4,
A plate may be placed horizontally between the radiator frames 4, 4 in the upper part of FIG. 1, and an opening may be provided in the plate, and the opening may be opened and closed by a lid. Furthermore, the lid 11 is attached to the stopper plate 1 with the bolt 14.
3, but the invention is not limited to this, but it may be fixed in such a way that the lid 11 does not vibrate due to vibrations of the hydraulic power shovel body and can be easily opened and closed when opening and closing the lid 11. It's good. Further, in the above embodiment, the radiator and hydraulic oil cooler of a hydraulic power shovel have been described, but the present invention is not limited to a hydraulic power shovel.
