chilly evap mod/new enclosure

[bazx]

Here is a modification to the chilly evaporator that I used when using the new enclosure

In order for the new chilly1 enclosure to be able to rotate and be fitted to the cpu socket with ease and without the cap tube getting in the way


You need to get the cap tube as close as possible to the suction return or centre of the evap

i did this by drilling a hole the diameter of the cap tube i was using around 3mm from the outer edge of the suction return hole on the evaporator

Just deep enough so I could intersect it by drilling another hole at 90 degrees at around 2.5mm/3mm dia to allow the refrigerant to enter the evaporator

Then taking the 3/8 copper tube to be used for the suction return
And slightly crushing it to form a small flat around 50mm long for the cap tube
To sit in

Once the evap has been brazed and cleaned the cap tube can be soft soldered to the suction return along the flat to keep it nice and tight

Once you have the evap complete

You need to make a little mod to the inner enclosure

After crushing the suction return it will have increased in size across its width
So you will need to measure this and open up the centre hole shown here
In the yellow inner part

I also cut a 2mm 45 degree chamfer here to help things out

Looks good, it's a lot nicer when they rotate freely.

Nice Guide Baz, I will be doing this in the next few days when my suction line arrives

This is how a Evap has to look like!
Great!

Just the base really needs to be that clean, but its beautiful work. I simply have been widening the hole in the foam...

Actually it's not a bad idea to clean it up real good like he did. Remember the other day Walt was talking about the leak that didn't leak? Underneath that excess solder could have been a leak waiting to happen. That's why I always clean mine.

Like you say though N.O.L. - it's nothing you have to do.

Nice job bazx but where's the mod?

Very true ron, I didnt even think of that.

Ron can you see the difference between the way i drilled the cap tube hole in the evap

And the way the hole is drilled in this unit

My intention here is to get the cap entry point closer to the centre

Allowing free movement of the enclosure or are you saying you already do this?

No I never did locate the cap tube like that. Great idea!!

My mistake, I thought you ment you modded the enclosure.

I find the same problem with the enclosure myself. It is very difficult or dangerous to twist the enclosure to line up with mobo holes. That is the main reason we are making the part of the enclosure where the insulation is , round. That way the insulation can lock down on the evap no matter where the cap tube and suction are located. You will be able to spin the insulation and evap inside the enclosure.

Sounds like a great idea to fix the enclosure like that as it will make the whole evap
Assembly much easier in the future

When do you think the modified enclosure will be ready to ship?

less than two weeks -

simply and good mod bazx

less than two weeks -

this will be make on injection machine ??
I have the same idea some times ago, but three pieces enclousure: muff, holddown and foam
Three pieces because I don't have form to injection machine

Enclosure is not injection molded. Machined 1 pc.
Insulation is 2 pc.
