An air-to-air intercooler comprising a charge air inlet 15 and outlet 16, a front face 8 via which ambient air enters the intercooler, a rear face 7 via which ambient air exits the intercooler, and an ambient air flow control device 10 located on the rear face and controlled based upon the temperature of the ambient air exiting the intercooler. The flow control device preferably includes a number of flow control members, for example rotatable slats 11, opened and closed by a single temperature responsive actuator 20 or by individual respective actuators. The front and rear faces may be of a heat transfer unit, which may be a heat transfer matrix. Preferably, the flow control device extends along only part of the length of the heat transfer unit and is positioned at the charge air inlet end. The invention reduces the risk of condensation forming within the intercooler by avoiding overcooling of the charge air. |
