Abstract: A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, particularly a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, and wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device in the closed position of the door element, when the cooling device is in the slide-in position.

Abstract: A system for reducing the time that it takes a vehicle fuel cell engine to reach its operating temperature at vehicle start-up. The system includes a radiator and a fan, where a cooling fluid from the engine is directed through the radiator where it is cooled by airflow from the fan during high load conditions. The radiator also receives ambient air through a front grill from movement of the vehicle. During vehicle start-up, when the engine is below its optimal operating temperature, the fan is operated in a reverse direction at variable speeds depending on the speed of the vehicle, so that the airflow through the grill that may otherwise convectively cool the engine is significantly reduced or eliminated.
