Abstract
A heat exchanging system includes two cooling fans for cooling heat exchanging medium of a heat exchanger, and a control device for controlling rotational speeds of the cooling fans. The control device is attached to an outer surface of a fan shroud so that radiation fins of the control device is disposed inside the fan shroud. Further, the radiation fins of the control device is disposed between two fan accommodating portions each having a cylindrical shape. That is, the control device is disposed in a comparatively large space formed by two fan accommodating portions. Therefore, the control device can be readily attached to the fan shroud on a vehicle, and the size of the radiation fins can be made larger. Thus, the heat exchanging system cools the control device sufficiently while improving ventilation performance of the cooling fans.
