Default tda8924 power supply

Hi

I have some tda8924 chips, Im maybe the first one here who has these
Anyway, I have made some simple ab amplifiers but never d-class.
is it real that +-24v gives 240w rms?
And I would like to make converter 12vdc to +-24v dc 500w as the two chips needs. Maybe someone has some good circuit for that.
the chip itself is so small 2x1cm maybe max. There are written in the datasheet that it gives 37w heat if listening with max 240w. Even the 37w heat seems too much for so little area to give the heat away.

Here is the datasheet:
