See http://ww4.choice.net/~pbfred/Horizontalsphere.htm where I run a test which to me indicates that heat can flow easier downwards than upwards. Refridgerators are build on the principle that coldness can flow better downward than upward. To me this is another indication that in a solid heat can flow better downwards than upwards. Also it is written on cold pack to put them on top of the food for coldness flows better downward than upwards.
