I have a design engineer that specializes in heat exchangers as it is what he does for a living. He has thrown in some input and done some calculations on the subject and thinks the design i just came up with should do pretty good. I have a 1/2" wide 3/8" deep channel that lets the water flow very well and with the semi maze design it has planty of serface area. if I can hold 4C above water temp with 1/4" barbs and a 185GPH pump and an Aluminum block I am doing something right. The flow is great. It comes out the water block nearly as fast as it goes in.
I have already got the kinks worked out and the code written up for the CNC mill for the final version. I will make some up after new years and send them off for review. The Aluminum block should perform aswell if not better than Danger Den's Maze 2 and only cost no more than $25 US. the Copper version will be around $30 or so. We will see what the reviewers say in about a month.
