Abstract
Embodiments discussed herein include an inverter with a multi-part housing and internal cooling-air duct. In one example, the inverter can comprise a first housing part with direct current connections, a second housing part with alternating current connections, a third housing part for accommodating power-electronics components of a DC voltage converter, a fourth housing part for accommodating power-electronics components of an inverter bridge circuit, and a heat sink. The housing parts each have an essentially planar rear wall and are arranged in such a way that they enclose a cooling-air duct with an essentially rectangular cross section, wherein the first housing part is arranged opposite the second housing part and the third housing part is arranged opposite the fourth housing part. The heat sink has two essentially planar cooling faces opposite one another arranged in the cooling-air duct.
