I think you need a special core to do this. If you push air into the core from one side and let it exit on the same side (assuming you use a standard core), the air will not be cooled because its flowing the fastest way out and not through the core.
The air should enter the core from the bottom left, flow to the right on the lower side, then turn around 180° and back from right to left on the upper side and exit. There are some cores with this design on ther market.
