Abstract
A construction machine of the present invention is provided, in a compartment formed by a cover, with an engine, a centrifugal fan, and a heat exchanger for exchanging heat between cooling air blown by the centrifugal fan and a specified medium, wherein the centrifugal fan and the heat exchanger are arranged further upstream than the engine with respect to flow of cooling air, so that cooling air sucked in by the centrifugal fan is led to the engine after passing through the heat exchanger.
