A fan unit for cooling units, such as electrical / electronic components, devices and the like

The blower unit has a supporting body are disposed on the at least two fans with fan wheels. You create airflow to cool the unit. In order to obtain optimum acoustic characteristics in a compact form and good efficiency, the fans are radial. The axes of rotation of the impellers of the centrifugal fans are at an angle to the axis of at least one flow-through opening of the support body, which connects an interior space of the support body in fluid communication with an ambient space. Due to the angular position of the rotational axis and the axis of the flow-through to each other, the blower unit can be made very compact so that it requires little installation space.
