Could it be done with a lathe and a mill?

Balinju · 05-08-2003, 11:01 AM

I guess you would need a rotary table too :shrug:

I doubt that a lathe could be useful here....

Balinju · 05-08-2003, 05:55 PM

i have a suggestion for you, maybe it will increase performace a little in the block. i would make some dimplets around the centre, under the inlet to produce more turbulace.

if you did not understand me, look what we (me and hara) did to our block (look around the cone)

Dimplets...sure...they are easy to be made.
Here is a change in design according to your block (dimplets not visible).

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!

bigben2k · 05-09-2003, 01:01 PM

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

Balinju · 05-09-2003, 01:02 PM

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

with your cad skills

Balinju · 05-09-2003, 01:04 PM

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

Balinju · 05-09-2003, 01:05 PM

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

hara · 05-09-2003, 01:33 PM

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.

Balinju · 05-09-2003, 02:16 PM

i think actually your block would perform better with those spirals

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??

Fixittt · 05-09-2003, 03:24 PM

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....

Balinju · 05-09-2003, 04:44 PM

are those measurments in mm?????????????????????????

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

Balinju · 05-09-2003, 04:49 PM

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

(the blue spots)

#Rotor · 05-09-2003, 06:22 PM

allow me to drop an asteroid into the pond

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...
