Abstract
Official abstract text for this publication.
A control unit for a vehicle with at least one electric motor and a transmission includes a housing and a heat sink. The housing supports transmission control electronics and converter electronics for controlling an electric motor. The heat sink is arranged between a housing upper part and a housing lower part such that the heat sink forms a part of the housing. The housing upper part is arranged on a raised peripheral rim of the heat sink in a thermally conductive way such that the housing upper part and the heat sink form a media-tight cavity. The converter electronics are connected directly to the heat sink, and the transmission control electronics are connected to the inner side of the housing upper part such that the transport of heat takes place from the transmission control electronics, via the housing upper part, to the rim of the heat sink.
First claim
Opening claim text (preview).
What is claimed is: 1 . A control unit for a vehicle with at least one electric motor and a transmission, the control unit comprising: a housing configured to accommodate transmission control electronics and converter electronics for controlling an electric motor, the housing comprises: a housing upper part, and a housing lower part; and a heat sink, the heat sink arranged between the housing upper part and the housing lower part in such a way that the heat sink forms a part of the housing, the heat sink including a raised peripheral rim, wherein the housing upper part is arranged on the rim in a thermally conductive way such that the housing upper part and the heat sink form a media-tight cavity for accommodating the converter electronics and the transmission control electronics, wherein the converter electronics are connected directly to the heat sink in a thermally conductive way, and wherein the transmission control electronics are connected to an inner side of the housing upper part in a thermally conductive way such that a transport of heat takes place from the transmission control electronics, via the housing upper part, to the rim of the heat sink. 2 . The control unit of claim 1 , further comprising a heat-conductive material providing a thermally conductive connection between the converter electronics and the heat sink and a thermally conductive connection between the transmission control electronics and the housing upper part. 3 . The control unit of claim 2 , wherein the heat-conductive material is a heat-conductive paste or a heat-conductive adhesive. 4 . The control unit of claim 1 , further comprising at least one connector mechanically connecting the transmission control electronics and the housing upper part. 5 . The control unit of claim 1 , further comprising at least one connector connecting the housing upper part and the heat sink to each other in a thermally conductive way and mechanically. 6 . The control unit of claim 5 , wherein the at least one connector is a screw or a rivet. 7 . The control unit of claim 1 , further comprising a flat shield arranged in the housing upper part between the transmission control electronics and the converter electronics. 8 . The control unit of claim 1 , further comprising a sealant is arranged between the rim of the heat sink and the housing upper part. 9 . The control unit of claim 1 , wherein the housing upper part is a deep-drawn sheet-metal part. 10 . The control unit of claim 1 , wherein the housing upper part is an aluminum high-pressure die-cast part with cooling fins.
