A heat exchanger comprising a body part and a cooling fin system having an inlet end and an outlet end. The cooling fin system has a plurality of cooling fins, and is adapted to provide a flow path for a coolant flow through the cooling fin system in a longitudinal direction. The coolant flow is adapted to enter the cooling fin system through an inlet surface of the cooling fin system. The inlet surface of the cooling fin system is a non-planar surface.

A fan apparatus is disclosed having a first fan and a second fan, both of which are centrifugal fans. Impellers of the first fan and the second fan can be located adjacent one another and adapted to rotate in opposite directions. A first outlet opening (ot) provided on a housing of the first fan can be located relative to a second outlet opening (ot) provided on a housing of the second fan such that a flow pattern of the first fan overlaps at least partially with a flow pattern of the second fan when viewed from a direction of a rotation axis of an impeller of the first fan.

A capacitor fastening for fastening a capacitor to a panel, whereby the capacitor, when mounted in place, is positioned in the panel, fastened at its lower part. The capacitor fastening includes a retainer in the panel at the mounting point of the capacitor for preventing lateral movement of the capacitor in at least one selected direction; a tightening plate arranged above the panel and to be fastened to the panel, which tightening plate has a hole substantially corresponding to the diameter of the capacitor above the mounting point of the panel; and a wedge between the panel and the tightening plate for tightening the retainer of the panel and the edge of the hole in the tightening plate from opposite directions against the capacitor.
