Cooling device, in particular for the cooling of accommodated in a control cabinet components, and to a corresponding use and method

The invention relates to a cooling device, in particular for the cooling of accommodated in a control cabinet components, with a first fan for the flow of a first heat exchanger with control air and a second fan for the flow of a second heat exchanger with ambient air, characterized in that the cooling device further comprising a power supply (1) with an upward and / or down-converter (2) which is connected via a rectifier (3) with a wide range input (4) for single or multi-phase AC voltage, and a capacitor (5) charges to an intermediate circuit voltage which is above or below one at the wide input range (4) applied mains voltage, a power supply unit (6) of at least one of the two fans in parallel with the capacitor (5) is connected. The invention further relates to the use of such a cooling apparatus and a corresponding method for the operation of the refrigerator.
