Construction machine with machine component

The machine (1) has a primary drive (2) configured to generate waste heat. Multiple machine components (4) are arranged in an area of the primary drive. A housing accommodates one of the machine components and includes a flow passage through which ambient air is sucked using underpressure or ambient air is supplied using overpressure such that air current is created. A fan generates pressure difference that creates the air current. The primary drive includes a cooling device for generating the pressure difference. The housing includes cooling fins that extend into the flow passage. The machine components are selected from a group consisting of electric or electronic components, hydraulic components, tanks and arbitrary components. The primary drive is an internal combustion engine.
