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 substantially as a plate, where a first biggest cross-sectional area of said plate is extended along and within a first transmission side of a transmission housing, said power electronics unit is fixed to said hybrid vehicle 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) has a total thermal conductivity corresponding to less than 10 degrees temperature increase on a Kelvin-scale 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. |
