Question about the radiator

I have six radiators(170mm X 145mm X 50mm) , plan to make ZEN V4 I wonder whether it is enough or not?

From my experience, you need about 65cm^2 per watt of dissipation. The amplifier dissipates about 90W per channel, so I think that your six is just about right for one channel. Oh, that is with a separate heatsink for the transistor in the voltage regulator. Seven for each channel would be ideal. You could build one channel with the six you have, but it would be a bit warm. No disaster.

I hope you can find six or seven more!

We usully call them "heatsinks," but you are right, they are indeed radiators.

Good luck!
 
Hmm - those heatsinks looks very same as the ones I used for my Zen v4 prototype ... They didn't seem - but they were OK (when bias was set to arround 1.3 A) - BUT - you must allow air-flow from both sides!
Well - OK - mine are 100x115x65; so they are quite smaller - well later I've found a datasheet for them - each one has K/W koefficient arround 0,7K/W ..
