An air-to-air intercooler 5 comprising a charge air inlet 15 and outlet 16, a heat transfer unit 17, for example a matrix, having a front face via which ambient air enters and a rear face via which ambient air exits, and an ambient air flow control device 10, positioned towards the inlet, preferably on the rear face, and extending for less than the full length of the heat transfer unit, preferably less than half the full length, controlled based upon either the temperature of the charge air exiting the heat transfer unit or in the outlet. The flow control device preferably includes a number of flow control members, for example rotatable slats 11, opened and closed by a powered actuator 20, for example a rotary or solenoid actuator, in response to the temperature sensed by a sensor positioned in the outlet. The intercooler reduces the risk of condensation forming by avoiding overcooling of the charge air. |
