Kheldar, I did that experiment. It takes a bit more work to simulate the system, though. With what you are describing, the force vectors from the outlets are pointing toward the center of the bucket, hence no swirling. If the outlets are cut in an oval shape and hoses are strung into the bucket and taped down to the sides (similar in layout to the block picture), the force vectors are now forcing th flow in a circular pattern.

The whole idea of this block is to solve the problems with EVERY block on the market.

1) The coldest flow needs to hit closest to the core. By having the entry directly over the core being forced downward, we are achieving that.

2) Stagnant water flow, or "slow spots" need to be eliminated. Even in the elegant design of MeltMan (see his post, he has an easy and outstanding design idea) keeps the fastest flow on the top of the block and the flow nearest the core is slower. By causing a swirling in the block, ALL areas of the block are in motion at all times eliminating slow spots.

The caveat is that the water stays in the block a fraction of a second longer (depending on flow rate), but since the coldest flow is hitting the block, this would possibly facilitate heat xfer.

3) You want minimal resistance in your block. There is no switchbacks in this block. It shouldn't slow flow much more than an elbow. You'll probably have as much slowdown in the Y adapter after the block as you will in the block.

4) Wh1rlp00ls are n33t. Talk about bragging rights! Heh. While this is unsuitable for peltier use (since the cooling is only going to be spread over about a 30-35mm diameter circle, it won't evenly cool the pelt), it should ensure maximum cooling of the core.

Upon further thinking, you could build arc shaped channels parallel to the flow of current to ensure circular flow, but it would increase manufacturing complexity. True, it could provide for more revolutions in the water before it exited the block, but even if the water only completes 1/2-3/4 revolutions, it serves its purpose. The entire purpose of the swirling is to agitate the entire coolant mass in the block to keep it at maximum speed. Any more swirling than that might hamper flow and efficiency. I'm trying to figure out an easy way to make something like this (I've got a good idea on that).
