Indeed the newer dual sided pqfn packages are really neat, both from a thermal perspective but also electrcally. The lead inductance on those is quite low and so also very exciting.
Though in this case the op is using to220s. I've never seen to220s with the dual sided cooling .
However it gets accomplshed, more cooling is the way to lower temps.
In many cases this could be something as simple as adding a better thermal interface material between the device and heatsink.in other cases the only way to get there is through more drastic measures such as adding more heat spreading, thermal mass or making what is already there work more efficiently.
