But that's why there should be a fan inside the case to move the static air around inside (recirculating within the sealed case), as well as something outside the sealed case - road air, coolant pipes, forced air from a fan, etc - cooling the casing. That should be more than enough to cool the pack internally.
This could actually backfire in areas with high ambient, such as Phoenix, making the cells hotter during the day!

It's on-board. While it is possible to do this externally, it would be significantly more expensive, as well as being cumbersome and a hassle to use. On-board it's automatic, and you don't have to do anything more than you currently do, just plug and go. Externally it would require lugging the "box" around, which would have to be built to handle this, (read: Heavier) along with the expensive and bulky CHAdeMO connector. Then you'd still have to provide power, which means you'd now have 2 power cords. I can see the logic in making it off-board when you get around 10kW or higher, but as long as you can easily power it from J1772, it's more sensible to have it on-board.
The only argument I can see for off-board is the fact that it has to be installed. While the process is easy, (and makes no permanent modification to the Leaf) it's nonetheless still something not everyone will be able and/or willing to do.
The 6.7kW upgrade is mainly targeted at fleet operators.
