Man, I love your CAD skills. VERY VERY NICE.

I recently had gotten Master Cam v9 and managed to get some tutorial books. Now Ll I have to do is get myself to sit down and learn it. That is always a hard thing to do.

I have gotten pretty descent in solid works and am hoping to bring my designs over into master cam.

Also, I finally got my CNC machine back from a friend who has had it for almost a year. So now maybe Just maybe I can start the learning all over again fresh. Hopefully produce some crap!

Nice! but you still need to get rid of the inner chamber wall: there's nothing to cool there.

no no wait you interpreded me wrong. I didn't say that you have to change you other channels or tubulante fins to spiral, i just posted that picture to make you see the dimplets. that spiral design, i don't know how much it will help in your case. my point was to make some dimplets between those fins.

but you still managed to make me say :eek: with your cad skills

wow 3 posts in 3 minutes. when i was writing my post, the last one was posted by tex707. when i clicked submit reply, i found another 2 post after that :eek:

btw i agree with ben, i think that wall is there for nothing

and i think your block is too tall (thick).

Thank you...

It's good to work with CAM as well, so you are on the right track for sure. I intend to start learning some CAM, but, unfortunately, have no access to a CNC machine...:(

Here's a close up...

I am aware of that...however, still want some comment on this. I have provided that wall just to keep some water trapped inside that inner chamber hoping to get some local turbulence...if you take a closer look you will notice that there are 6 "exits" for the water made in the wall, made with different cross-sectional areas to ensure correct separation of the flow around the outer groove (or channel, if you like).

No, I'm not....I have said that the dimplets are not visible on the screencapture...:)...I'm aware what you are trying to tell me...

Glad to see that you guys like my CAD.

Do you think it could hurt the performance?

Ok, I didn't see that logic, until you explained it. It would be nice if you could run a plastic prototype through flow testing, then figure out if it's really needed. Otherwise, it only adds to the pressure drop across the block, and unless you plan to use a hefty/beefy pump, you might be missing out on some extra performance.

Yes, the extra height lowers your flow speed, which decreases turbulence.

i think actually your block would perform better with those spirals :D

Very nice looking, and they would not make the same restriction as the fins you put in your block first, but it would be very very difficult to mill. how wide are the channels between each spiral fin??

Tex email me the cad files from that last render you just did, the double spirals. I wanna play with it some and see if I cant machine it.


that is if you dont mind.

As I have said previously, this block is, very likely, never going to be made. A person who this block was intended for has taken it to the workshop and people there told him that it is too much trouble to machine it, so I made another, much simpler design.

I don't have enough courage to show you guys that design....:)

Could you, please, make it more clear for me what you mean when you mention flow testing.

I am aware of the machining problem with this design...:(

Here's the dimension....

are those measurments in mm????????????????????????? :drool: :drool: :drool:

how is it possible to mill in a circular direction with 0.59mm endmill :eek: :drool:

i think that now you will have to reshape the "holes" in the second wall from where the water exits. Hope that you understands my next diagram.

the circular motion of the water will not let it pass with ease through certain walls because of their direction.

i also included the dimplets for you :dome: (the blue spots)

allow me to drop an asteroid into the pond :D

don't design the block with the aim to make life easy for the coolant to get through it.... that is what bigass pumps are for!

design the block to maximize the energy stored in the velocity of the coolant, by converting it in as much turbulence as possible. Turbulence is the "scrubbing agent" you need to get the hot layer of coolant hugging the surface of the block, to let go.

you will find this philosophy to have a double edged effect, in the form of....... the more imaginative the turbulating inventions are you come up with, the more surface area you are going to end up with... Now that is a double positive. Believe me! not too many of those around these days...

Yes, this is in mm...and no, it is not possible to machine this...not easily, anyway...:)....however, maybe the following could be.:

You are definitely right about this...

It looks like I'm going to move that inner wall for good...:)

This ia a good idea...and easy to be brought to life...

Maybe we should try to provide "vortex generators", a solution used in aerospace engineering for creating local turbulence...

That would take a looong time to program on a cnc. Also, keep channels to dimensions like for example 1mm 1.5mm 2mm. Get it?

hey man, if you remove that wall it will become exacly as our (me and hara) block.

if you want i can send you the cad file of it. it has 10channels of 2mm each. originnally it was designed to have 1.5mm channels and 12 channels, but the machinist had no 1.5mm endmills for us so we had to change the design a little bit.

Balinju and hara, would it be possible for you to send me your CAD files just for me to take a look at them? I want to try to see how to work it, lol...

Which CAD program do you use?

Sure, I know what you mean. However, I think that if one doesn't keep a "standard" channel dimension, that could lead to only one more tool pass per channel, right?

Sure, I would like to see the CAD files you've made...please e-mail them.

BTW....how do you like this design...it is similar to the one you've made, with a little extra:

Ooooops….I apologize for the mistake….here’s the assembly as it should look like.

give me your email or prv me your email, one of them and i will send you the cad file. we used autocad, and secondly sorry for the delay in time, yesterday I had my Maths A-Level Exam. No more maths for this year :evilaugh:

ok to say what differences there are from your design to ours, our dimplets were way smaller. 0.7mm each. we opted for 0.4mm but the chunk of that kind of drill bid was wider than the space between the channels and the cone, so we had to do with 0.7mm. secondly we have that cone in the middle, its there for turbulance, and flow separation. then that outer line you have made at the end of the fins. that is extra. that channel is way outside the cpu core, it will only restrict the water flow.

If i were you, i would make those spirals more twisted than the block we made, and make more spirals, or channels.
Nigozeg once posted his idea which was somthing similar, but with extremely small spirals and extremly long channels which was extreemly impossible to cnc it.

i would like to see improvements on that design though ;)
