Abstract
The invention relates to 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, characterized in that the fan unit comprises an air guide geometry, so that air exhausted from the radial fan is redirected into the main flow direction.
