Cooling device for cooling a switchgear cabinet

A cooling device for cooling of a switchgear cabinet, comprising an air inlet side for warm air and an air outlet side for cooled air, wherein a heat exchanger and at least one fan unit having a radial fan are located between the air inlet side and the air outlet side, and wherein the fan unit creates an air stream through the heat exchanger having a main flow direction between the air inlet side and the air outlet side, wherein the fan unit is located in the main flow direction behind the heat exchanger, and wherein the fan unit comprises an intake and an ashlar-shaped fan box in which the radial fan is received, wherein the fan box comprises an air outlet at at least one of four sides oriented parallel with respect to the main flow direction and parallel with respect to a rotational axis of the radial fan, characterized in that the fan unit comprises an air guide geometry, which air guide geometry comprises an end section that is connected to and extends perpendicularly from a side of the fan box to a 90°-curvature, so that air exhausted from the radial fan is redirected into the main flow direction, and wherein a separative element extends from the side of the fan box, and the end section of the air guide geometry and the separative element extend the same height from the side of the fan box, wherein

• the cooling device further comprises a plurality of fan units, wherein adjacent fan units are arranged in such a way with respect to each other that they adjoin to each other at least in sections along their respective air guide geometry, and
• wherein the plurality of fans form a fan assembly with a suction side and an exhaust side, and the fans in the fan assembly are stacked one above the other so that the suction side of the fan assembly is fluidically separated from the exhaust side, and
• wherein the end sections of adjacent 90° bent air guide geometries that are placed at the same height as free ends of the separative elements are configured to be stacked one above the other;
• and
• wherein the end sections of adjacent 90° bent air guide geometries that are placed at the same height as the free ends of the separative elements are configured to be form-locking to one another.
