New Atomizer Prototype

[crazyhorse]

Thanks rkd. That's disappointing. For some reason I had the warped notion that borosilicate may be highly conductive of heat. Ah well, can't make diamond out of doggie doodoo.

Proceeding on to the next brain fart, I wonder how a nichrome coil dipped in molten copper would do? Or a coil plated with high % silver solder?

I've got a question (maybe important IDK). I remember reading something a while back about PG (or maybe it was VG) turning from lovely vape to deadly poison gas at a certain temp.
Again, I have tried to go back and find this info now that I am looking into playing with atty re-design, but I can't find anything.
Has anyone else heard of this?
Anybody know what that critical temp is? for PG? for VG?
I've got lots of ideas on efficient ways to get a hot vapor producer (lots of great ideas on this thread too BTW) but I don't want to go "d**k in the dirt" in the process.
Any answers or insights would be greatly appreciated.

Search for "acrolein"
This looks promising:

As you guys toy with ideas for new atomizer designs (and believe me, I'm all for it!), there's something that you really need to think about. And that is thermal efficiency and insulation.

Look at the traditional 510 atty for example. Generally speaking, the thing consumes something like 4W. Of that 4 watts, a tremendous amount of that power is WASTED! Feel the outside of the atty body.. often it is smoking hot! That means that power, a LOT of power is being used to heat the atty body and internals, parts that do not generate vapor. You want the power to generate localized heat.. heat right where the liquid is being vaporized. And you don't want any of that heat to be conducted, convected, or radiated away to parts that play no role in the actual production of vapor.

Just think how much longer your 510 batteries would last if they weren't wasting a substantial amount of their capacity just heating up the outer shell!

Just something to think about.

Would this be to prevent the Nichrome from touching the liquid? Because copper can be toxic too. Not sure about silver...

It seems like cartomizers would be the most efficient since the first thing they heat up is the juice vs. a metal bridge, air, etc. Also, if we're going for insulation, I guess we should just model the way a thermos works. I think the best design will be some sort of cartomizer built like a simple thermos with an internal heating element.

Not that it really matters, but I'm still stuck on glass.... And looking at this, 'cus I'd be able to use it for other things too...

the best way for temperatur regulation is when you make a condom with

porcelain on this atomizer then we have not a high temperature !

Don't know costs, but something like this may help. enclose the coil...

and this. Maybe something like this could encapsulate the coil, or partially?

Looking at Jacko's first link, the smallest they make is 10mm OD. E-cigs are typically 8mm.


Then I thought: Who cares? E-cigs were made to resemble cigarettes. Do we really care, especially those of us with 3/4" Chucks or Prodigies?

Bigger diameter = bigger coil = more vapor?

Stuck on glass as well, that looks excellent. Looking into maybe taking a glassworking class even (just from looking into this project, it looks really fun ).

Wouldn't using glass be better and safer though? I posted a link on page 2: Pyrex Glass Tubing, 4mm OD x 0.8mm Wall Thickness 12" Length (Pack of 5) - $2.95 (Amazon)

We would also need high-temp, food-grade epoxy if it was exposed to the liquid.

Well, I guess my ultimate goal is a 100% DIY ecig. I'll probably go with a larger diameter just so I can use bigger/cheaper batteries. I don't know much about ecigs other than the 510 but that thick Bling ecigar looks pretty sweet. With one that size, it should be real easy to slide batteries (AAs or CR123's or some standard, readily available size) in/out like a flashlight vs. special, thin $12 batteries.
