Water Block thickness question???

jaydee · 03-13-2002, 07:43 PM

What do you think is the ideal thickness the material should be for the WB? 1/2" 5/8" 3/4"??? I have benn using 1/2" for the main part and 1/8" for the top. I see DD used 1/2" for the bottom and 1/4" for the top. Looks like Fixittts Spir@l uses 3/4"??? Hummm, would a taller block with a deep 1/2"-5/8" channels be better?

Anyone try different sizes?

But then wouldn't the water slow down through the block?

Can't see why. If you are using a 1/2"id barbs it should work great with a 1/2x1/2" channel.

But is to much material a bad thing as it may store to much heat or something?

The water would be slower with a larger bore size. But if you decrease the width of the chanels you can still have the same flow velocity with a larger surface area (useable). Plus the base should bve quite thick for heat spreading, I can't remember the optimal value for a maze2 size block on a tbird but it was around 1/2 inch in copper, more on Al. But that would make it too heavy for me.

PS. Ever get any info back from those heatpipe heat spreader people?

Nope, not a thing.

How rude of them. ;']

1/4" thick base, 1/2" tall channels, 1/4" top

I use 1/4" bottom with 3/16" top, most of the time but is changes with custom jobs..... the base thikness is also not constant... (VDFC)

very cool #Rotor, that pic and the theory are very very interesting.

Came up with the idea a couple of months ago, while building a HD block, and I had to device a way to insure uniform cooling over a large area.... turned out to be very effective, in all my other blocks too, anything that uses a grid design, can utilize this concept, and as everyone know

I Like my grid designs, gives me the ability to make blocks of allmost any shape an size,

Thanks for the input guys. Working on ideas for next layoff season.

I will try a monster block like Brad describes. 1/4" base, 1/2" deep channels, and a 1/4" top. Thats is 1" thick block!!

Also I want to try a grid design!!! I like the looks of it. I got a new drill press to do it with to.

jaydee, I've seen simulations where 6.5mm thick base is the best. the channel depth is just logical with 1/2" inlet, and the top is just what would be easiest.
