Cooling device, particularly a cooling device for cooling a switch gear cabinet built-in part, use of the cooling device, and a cooling method for the cooling device

摘要

The disclosure relates to a cooling device, in particular for cooling components that are housed in a switchgear cabinet, comprising a first cooling fan for blowing air from the switchgear cabinet through a first heat exchanger, and a second cooling fan for blowing ambient air through a second heat exchanger, characterized in that the cooling device further comprises a voltage supply having a step-up and/or step-down converter, which is connected via a rectifier to a wide-range input for single-phase or multiphase AC voltage, and which charges a capacitor to a DC link voltage which is higher or lower than a mains voltage across the wide-range input, a power supply unit of at least one of the two cooling fans being connected in parallel to the capacitor. The disclosure further relates to the use of such a cooling device and to a corresponding method for operating the cooling device.
