New Coil design

[locke2121]

I've been looking at coils for a while now...and they all seem to follow the same theme...wrap the wick with wire and hook it up! Well...lets look at some facts. The purpose of the coil is to burn off or atomize the fluid in the wick. But in reality, the wick only burns off the fluid on the OUTSIDE of the wick..leaving the middle fairly wet. So what about a new coil design. I call this the zipper coil. I really think it would be for DIYers because of the time involved. Basically, instead of wrapping the wick with wire...you zip it back and forth THROUGH the wick. There is wire on the outside of the wick...and some running straight through it. I honestly don't know if it will work, I haven't bought any wick or wire to attempt it. This was just something tickling the back of my brain and I had to scratch lol. So...if anyone wants to give it a shot and see if there is better vapor production from this...please throw some results, good or bad, back at us!

I did a coil with SS mesh as a wick and diaper around the coil, originally to eliminate the cotton in dual coils, later I used it with success as a drip coil. It is a ..... to keep oxidized.

I am eventually going to try a straight piece of nichrome wrapped in stainless. I would need a high resistance wire, so it would be thin and maybe prone to breaking. Any thoughts?

Here is one I did a while back with 32awg. The wire was wrapped in the mesh and half way thru the wrapping it was folded back down and the remaining mesh wrapped around the two. 3.5 ohms and produces good vaper at 7v. Have to invent something to use it in..lol

This idea may work okay with ss, as it looks to be thinner, but I don't see it working well with fiber silica or fiberglass. The coil wrapped around the wick properly, with the proper supply of juice, will atomize the juice that lays on the wire. With what the OP is suggesting, the part of the wire passing through the wick, one would think there would be a flooding effect on that part of the coil that is covered with the wick. The covered part in the wick would have to get hotter to atomize, than the wire on the outside. The outer part of the wire would naturally tend to get hotter, thus a source of failure.
This is only my observation with having rebuilt many carto and attys. Not saying it wouldn't work, and if someone could get it to work, I think the results would be interesting. There has been a few surprises in my adventure of e-cig modding, so I'm not ruling it out. It just raises some questions.
I have never worked with the ss mesh, only silica fiber and fiberglass.

Ok...I'll throw this in for thought.....if you have a wire inside the wick vaporizing the liquid that vapor will immediately get reabsorbed in the wick around it...so your wasting a lot of energy.

Had that thought, just not in those words, which makes sense.

 

[locke2121]

ah....I didn't think of that! The outer "layer" of juice would have to atomize FIRST...then the inner layer...hmmm...back to the drawing board he he....maybe an inner coil and an outer one....if it could be done.

And I hear good things about SS mesh...I just prefer something I can use straight out of the box without having to spend a bunch of time oxidizing it!

Just remember, T. Edison tried a lot of different materials, some being quite strange, before he came up with tungsten for his light bulb.

 

[locke2121]

yep...bamboo being one of the strangest!

And I thought seaweed was, lol. Or was it horse hair.

The stainless steel gets red hot from the wire in the center of the wick and it does put out good vapor.

My only argument against this is that while inhaling, air is swirling in and around the wick, passing through the center. I don't know though, I think I'm going to sit down and test all this out, the ideas been bugging me lol

Warning: the following statement was typed in a moment of lunacy. I will leave it here just for lulz.

Great discussion, peeps! Lemme throw in my couple of pennies...

In its current configuration, as air is drawn through the center "tube" formed by the wick, it forms a high pressure stream which simultaneously creates low pressure elsewhere inside the atomizing chamber. The vaporized liquid from the coil/wick junction gets pulled along or "hitches a ride", if you will, with this stream. Sort of like how carburetors work, where the air stream pulls fuel along with it.
I think if you place a coil within this high pressure stream, it would cool down the inner coil instantly, negating any usable vapor production from it.

I warned you. This is your brain on...

I'm missing something..how would air be swirling in the wick...the wick has liquid in it coming from the tank so it either has air in it or liquid. Strong air current around the coil is beneficial...just like fanning the flames of a fire.

What configuration is this..how can the wick act as the air inlet and still wick at the same time? Not saying there isnt...I just havent seen one like that yet. When you take a drag on the atty it creates a low pressure (vacuum) evacuating the chamber....atmospheric pressure...if thats what you mean by high pressure stream...would be rushing in to replacing the air/vapor thats being evacuated. Then again I only got an hour and a half of sleep last night so...............lol!

One benefit of having wire inside the wick would be that the heat would reduce the viscosity of the liquid in the wick and possibly help push it to the surface of the wick where the outer coil would easily vaporize the preheated liquid. But we are also dealing with an intense amount of heat in a small area already...so heating the wick is not the problem...its surface area of the wick thats available to create vapor.

Another member here..Sci...has had some interesting results by wrapping silica loosely around a wire...then forming the coil with that. He had some good vapor production...but I think he is still playing with the idea.

No by all mean...dont give up on the idea....I was just kicking the can a little also...I often have no idea what I'm talking about!!.....now where was I??

LOL! Forgive me, guys, but I just went back and re-read my post and I just realized I didn't just have a brain fart; more like brain ........!
I honestly don't know WTH I was thinking! When I read Nico's post talking about fanning the flames I face-palmed again! Why the hell I thought passing air would cool down a coil is... IDK. I must need sleep... or vitamins or something.
Sorry guys! Carry on.

LOL....I hear ya bud...but your right that an air stream directly at the coil will take the red hot off the wire some....but the vapor will start flying from the air blowing the liquid in the wick and making it contact the still very hot wire I guess. Now add a stream of pure oxygen and you would have a cutting torch!!! lol....well...and a melted wire!!

I dont know....I'm goin to bed!! LOL
