Why a large waterblock?

Who says I'm not already doing this nozzle design and just haven't showed the other side of the plate? It's not a perfect nozzle inlet in the ASME sense, but it's not a straight cut either.

The reason why the solid metal plate is there is to provide a strong bracing pressure against the tops of the fins. With the very thin base-plates I'm using this is an essential part of the design. I investigated the inlaid nozzle plate idea, but for the low volumes of blocks I'm making, the tooling costs required to setup and stamp out some plates or make up a plastic mount, it was cheaper to just get the copper plate made up as is.

But not nearly as "l337" looking

I've been experimenting some with molding tops for blocks from plastic resin. Sadly I have just tried with the stuff I had at hand, which looks like muddy water, as well as being quite brittle. It wouldn't work very good for supporting thin baseplates, but that could be fixed quite easily with an extra copper plate between the baseplate and the lid. It would be a good way to get smooth flow down to the cooling spot..

Now if only my father could hurry up with building his new place (building new house and a 2 car garage + lots of workspace + 2 car carport) I use his place for my experiments as my apartment isn't very well suited for this kind of work
