COOLING DEVICE, IN PARTICULAR FOR COOLING COMPONENTS HOUSED IN A SWITCHGEAR CABINET, CORRESPONDING USE AND CORRESPONDING METHOD

摘要

The invention relates to a cooling device, in particular for cooling components housed in a switchgear cabinet, having 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, the cooling device being characterised in that it further comprises a power supply (1) with a step-up and/or step-down converter (2) connected via a rectifier (3) to a wide-range input (4) for single-phase or multiphase alternating voltage, and charges a capacitor (5) to a DC link voltage higher or lower than a mains voltage across the wide-range input (4), a mains power pack (6) of at least one of the two cooling fans being connected in parallel to the capacitor (5). The invention further relates to the use of such a cooling device and to a corresponding method for operating the cooling device.
