PROBLEM TO BE SOLVED: To provide an engine-cooling device for a construction machine, having a separately-structured shroud consisting of a first shroud supported on the side of an engine and a second shroud supported on the side of a heat exchanger, enabling applicability to a compact construction machine and improved fan efficiency by making the installation space in an engine room smaller. SOLUTION: This engine-cooling device for a construction machine has a shroud rear portion 10b supported on the side of an engine 8 for enveloping a cooling fan 11, a shroud front portion 10a supported on the side of the heat exchanger 9 for introducing cooling air P into the shroud rear portion 10b, and a sealing member 43 for sealing them, while allowing relative displacement. An inside diameter Da on the downstream end 10a1 of the shroud front portion is made larger than an outside diameter Db of an upstream end 10b1 of the shroud rear portion and a downstream end 10a1 of the shroud front portion and the upstream end 10b1 of the shroud rear portion are set so as to be at almost the same position in the horizontal direction. |
