A charge air cooler arrangement, a charge air cooler tank, and method are disclosed. The charge air cooler arrangement includes a charge air cooler having an operable thermal transfer area configured to transfer heat from inside the charge air cooler to outside of the charge air cooler. The charge air cooler arrangement may also include a valve configured to change the operable thermal transfer area from a relatively large area to a relatively small area.

1. A method for an engine charge air cooler including an adjustable plate and a volume, the volume including a non-zero sub-volume and a non-zero remaining volume, comprising: passing airflow into the volume by moving the plate to provide inlet of the airflow into all tubes of the charge air cooler; andpassing the airflow into only the sub-volume by moving the plate to close off inlet of the airflow into the remaining volume, the plate including a first exposed area on a first side of the plate and a second exposed area on a second side of the plate, the second side opposite the first side and the second exposed area larger than the first exposed area. 2. The method of claim 1, wherein moving the plate to provide inlet of the airflow into all tubes of the charge air cooler includes moving the plate into an open position and wherein moving the plate to close off inlet of the airflow into the remaining volume includes moving the plate into a closed position. 3. The method of claim 2, wherein when the plate is in the closed position, the first exposed area is closest to the sub-volume and the second exposed area is closest to the remaining volume. 4. The method of claim 2, wherein when the plate is in the open position, the first exposed area is nearer all tubes of the charge air cooler than the second exposed area. 5. The method of claim 2, wherein moving the plate into the closed position includes moving the plate into sealing engagement with a hole of a divider, the divider dividing the volume into the sub-volume and the remaining volume. 6. The method of claim 5, wherein during passing the airflow into only the sub-volume, the first exposed area engages with the hole, the hole sized to expose the first exposed area. 7. The method of claim 1, wherein moving the plate includes providing a motive force to open or close the plate with an actuator in order to change the plate from an open state to a closed state but not providing force with the actuator to keep the plate open or to keep the plate closed. 8. The method of claim 1, wherein moving the plate includes hinge-ably moving the plate via a hinge coupled to a proximal end of the plate. 9. A method for an engine charge air cooler including an adjustable plate and a volume, the volume including a non-zero sub-volume and a non-zero remaining volume, comprising: passing airflow into the volume by moving the plate to provide airflow into all tubes of the charge air cooler; andpassing airflow into only the sub-volume by moving the plate to close off airflow into the remaining volume, the plate including a first side with a first exposed area and a second side with a second exposed area, the second side opposite the first side and the second area larger than the first area. 10. The method of claim 9, wherein moving the plate to provide airflow into all tubes of the charge air cooler includes moving the plate into an open position and wherein moving the plate to close off airflow into the remaining volume includes moving the plate into a closed position. 11. The method of claim 10, wherein all tubes of the charge air cooler include a first set of tubes defining the sub-volume and a second set of tubes defining the remaining volume, the sub-volume divided from the remaining volume by a divider. 12. The method of claim 11, wherein when the plate is in the closed position, the first exposed area is exposed to the airflow and the second exposed area is exposed to a static pressure resulting substantially from a fluidic communication between an outlet side of the charge air cooler with the second side of the plate via the second set of tubes. 13. The method of claim 12, wherein moving the plate into the closed position includes moving the plate into sealing engagement with a hole of the divider, the hole sized to expose the first exposed area. 14. The method of claim 13, wherein moving the plate to provide airflow into all tubes of the charge air cooler includes moving the plate away from the hole to allow airflow through the hole. 15. The method of claim 14, wherein the plate is hinge-ably coupled with the divider. 16. The method of claim 13, wherein moving the plate to close off airflow into the remaining volume includes moving the plate toward the hole to not allow airflow through the hole. 17. The method of claim 9, wherein moving the plate includes moving the plate via a hinge, the hinge positioned at a junction between a tank of the charge air cooler and a side of the charge air cooler. 18. The method of claim 9, further comprising passing airflow into the volume by moving the plate to provide airflow into all tubes of the charge air cooler when the engine is operating under hot ambient conditions. 19. The method of claim 9, further comprising passing airflow into only the sub-volume by moving the plate to close off airflow into the remaining volume when the engine is operating under humid or cooler conditions.
