An air to air intercooler 5 for an engine (2, fig.7) of a motor vehicle is disclosed in which a flow control device 10 is located on the intercooler 5 to vary the flow of ambient air through the intercooler 5. The flow control device 10 includes a number of louvres or slats 11 that are moveable between respective closed and open positions by an actuator (20, fig.3). The position of the slats 11 is adjusted based upon either the temperature of the charge air exiting the intercooler 5 or the temperature of the ambient air exiting the intercooler 5 so as to vary the temperature of the charge air flowing through the intercooler 5 and thereby prevent condensation of water vapour in the heat transfer matrix 6. |
