Usually the entire enclosure needs to be cooled. The cheap industrial way to cool a cabinet is to use a Exair type vortex compressed air powered cooler. They are relatively cheap, and bulletproof, but they eat a lot of compressed air. But if you have a lot of compressed air available, then that can be a good solution.
In general, I like to keep water away from electronics and high voltages... :-) Although... the low rider lighting is attractive.. ;-) I have worked on a few high power induction heating units that use water to cool just about everything, including the power conductors. I find them a bit scary. 480 volts, SCRs the size of hockey pucks, mixed with hoses and water all in the same cabinet! I close the cabinet and stand around the corner when I throw the disconnect switch on after a repair.
