How do I prevent my adapter from overheating?

I had this sort of problem in the Philippines for a TV adapter. Due to the extreme heat of the country and the lack of airflow the ac adapter was overheating and the TV would turn off after a certain amount of time. So I had on of those Gel Cooling Pads for a laptop which I was not using. Mine looked like this.

Anyway I wrapped it around the power adapter brick and rubber-banded it on.

OF course you might use something else but remember you are dealing with power so be careful.
