Switch cabinet for accommodating e.g. electrical and/or electronic component, has passage opening and channel section designed for installation of radial fan, such that recirculation air flow is generated from radial fan

摘要

The cabinet (2) has an air recirculation channel (10) for re-circulation of air from an inner area (6) of the cabinet. A passage opening (20) is formed from a channel section (22) of the channel, and another passage opening (60) is formed from another channel section (62). The latter opening (60) and the latter section (62) are designed for installation of a radial fan (64), such that a recirculation air flow is generated from the fan, where the air flow flows through an air-liquid heat exchanger (30) in a same flow direction as a recirculation air flow of another radial fan (24).
