Not meaning to hi-jack lee's topic, but I'd like to get some opinions on a design for a copper finned waterblock.
I'm studying Design & Technology at college and for my manufacturing project I've decided to attempt the creation of a waterblock.
So far
this is what I've come up with.
The green/grey thing is the lid and the purple thing is the base. I haven't added the three inlet/outlet holes on the lid yet because I'm not sure of the dimensions of the fittings I'm going to use.
What I am sure of is that the water will enter in the centre of the lid where the circular plane closes up into a slightly curved rectangle then passes over the fins and leaves from either side through two outlet fittings. The design was stronlgy influenced by previous images I've seen in this thread.
One thing I was uncertain about what the size of the fins. I've read this thread from start to finish, people tend to suggest 3-5mm so I made them 3mm tall.
They are 1mm thick with 1mm spacings and about 15-20mm in length. The thickness of the copper plate is 4.76mm and therefore the thickness of the base inbetween the copper fins will be 1.76mm (1.76mm of copper between the CPU core and the water).
The circular indents in both the base and the lid are for an o-ring.
I have free access to a CNC machine at college so this is what I'll use to make the block. The lid will probably be made from acrylic sheets. The thickest sheets of acrylic they have in stock is 3mm so I will probably laminate 5 layers together for the lid.
The newer copper waterblock will be replacing
this older aluminium one that I currently use.
Comments or questions are welcome.
