Abstract
A cooling system includes one cooling circuit configured to flow a coolant and to distribute the coolant at least throughout an integrated drivetrain assembly. The cooling circuit includes a fluid turbulent passage formed by a plurality of cooling spikes and arranged onto an inner surface of a heatsink configured for cooling at least one power switching device provided with the power inverter. The heatsink comprises at least one cooling plate with one corresponding cover, the plurality of cooling spikes are provided on the cooling plate and the corresponding cover. The plurality of cooling spikes include the cooling spikes with an increased or decreased size, the location of the cooling spikes with an increased or decreased size depends on the location of the electrical components provided by the at least one power of switch device so as to modulate the rate and flow of the coolant within the fluid turbulent passage.
