摘要： An inverter for converting an input-end direct current into an output-end alternating current to be fed into an AC voltage supply system includes a first housing part with direct current connections for receiving direct current lines of a direct current generator, a second housing part with alternating current connections for receiving alternating current lines of an AC voltage supply system, a third housing part for accommodating power-electronics components of a DC voltage converter, and a fourth housing part for accommodating power-electronics components of an inverter bridge circuit. 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 inverter also includes a heat sink, which has two essentially planar cooling faces opposite one another arranged in the cooling-air duct, wherein the cooling faces are assigned to the rear walls of the third housing part and the fourth housing part and are in thermal contact with power-electronics components arranged in these housing parts.

摘要： A seal for an International Protection (IP)-sealing and electromagnetic capability (EMC)-shielding connection between a first housing component and a second housing component of an electrical or electronic device is disclosed. The seal includes an elastomer-containing sealing body and a metallic support that is embedded to some extent in the sealing body. The sealing body and the metallic support are connected to one another in an adhesive and/or form-fitting manner and thus form a material bond, and the metallic support has a plurality of contact segments, which project out of the sealing body and are configured such that the contact segments make electrical contact in resilient fashion with a first boundary surface that is assigned to the first housing component, and a second boundary surface that is assigned to the second housing component, the seal being pressed in between said boundary surfaces in an installed state.

摘要： The disclosure relates to an inverter having a first housing module, a second housing module, removably connected to the first housing module, and power-electronic components in both housing modules, wherein a cooling air channel, opening in the surroundings of the inverter, is delimited in the circumferential direction partially by the first housing module and partially by the second housing module. The first housing module is configured to mount to an external structure and the second housing module is configured to mount to the first housing module. The cooling air channel extends at a distance to a mounting plane of the inverter defined by the first housing module opposite the external structure.

摘要： 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.
