Toro Rosso STR9 - cooling solutions 17 March 2014
The new 2014 power units mean all the teams have had to increase their cars' radiator cooling, leading to some quite complex layouts. Toro Rosso's is unique, with two oil radiators (1) cooled by a duct behind the driver's head (a solution that raises the car's centre of gravity), water radiators (2), intercoolers (3) (quite a heavy solution, but one with superior cooling results), and an accumulator (4) to manage the water temperature. Missing in this drawing is the pipe (5) that connects the turbocharger and the intercooler. Also shown is the wastegate (6) used should the turbo go into safety mode.
