Arrangement for a power electronics unit in a HEV (1, 16, 24, 42, 43), said HEV comprising a combustion engine (2, 17, 25), an electric motor/generator (3, 21, 28, 26, 41), a transmission (5, 18, 27), said power electronics unit is shaped as a plate. Said plate is extended along a transmission side, said power electronics unit is fixed to said power train with a first attachment point (10, 23, 33, 34, 39). All attachment points (10, 11, 13, 14, 15, 23, 33, 34, 35, 36, 39, 42, 54, 55, 59) have a total thermal conductivity corresponding to more than 10 degrees temperature difference on a Kelvin-scale between said power electronics unit and outside surface of said first transmission side and/or outside surface of said motor/generator for 5kW of heat originating from one side of said attachment point. Embodiments also comprising sound damping capabilities are disclosed. Advantage is less parts and increased functionality. |
