I have recently put a tumble dryer in a cupboard, some might argue it does not fit as there is not much air flow around the unit. As you can see i have a door above the main door. I would like to shut the main door leaving the top one open for air. I am looking to put a fan on the wall on the inside as high as possible.

My questions are:

Do i want the fan blowing air into the cudboard or blowing the hot air out of the cudboard?

Because i want it up high, should i have the fan pointing down towards the unit or towards the top door?

Thanks in advance and sorry if this is not the right sort of post for this page but who else to ask about heat than a thermodynamics engineer, am i right...
