Simple Nichrome Loop Around Wick Concept

[cadcoke5]

I just got privileges to create a new thread, and have also done a bit more investigation to determine some preliminary feasibility. So, here goes a new thread about creating a high density atomizer that is viable for a puppet stage smoke machine or perhaps a pipe.

Attached is an image of what I am thinking about. A simple loop of nichrome wire that is wrapped around a loop of wicking material. I think the wick can be a flameproof fiberglass ribbon, like that used for seals on a wood stove.

The idea is that there is a large amount of wick available to each portion of wire, as opposed to the standard tight coil of nichrome. The standard tight coil will tend to use up all the available juice when it is used for a longer than normal time period (i.e. over 5 seconds).

I've attached two images. One with a short, fat coil, perhaps best for a pipe. In this case, the nichrome may be best located on the inside of the wick, and actually threaded through the wick to facilitate drawing the smoke through the center. The 2nd version has the nichrome wrapped around the wick.

I don't have any nichrome wire to test these ideas out, but will probably order some soon. Any one else want to try it out?

I was pondering the idea of a round wick, and like your drawing of the same makes me want to get off my duf and find some of that wicking material to play with Thanks Man

Note the amperage values in the Current/Temperature Table. For estimating purposes you can assume that the amperage value for a *coiled* wire is roughly 50% less than the capacity of a *straight* wire as referred to in the table. (So divide amps in the table by 2 for your initial calculations)

Its a year later... Looks like the new cartomizers are using concept #2. Anyone remember the old bug be gone burners? Remember the shape of them? Incense?

And you came to this conclusion, how?

Drawing #2 looks a lot like a genesis atty.

You said.

That doesn't make sense. That coiling a wire reduces its amperage by 50%.It throws ohms law out the window. So something had to be missing.
Like this.
approx amperes to heat a straight oxidizes wire to given temperature.
(Note: For *Coiled* elements divide *straight* wire amps by 2 for approximation purposes.
That purpose would be to reach a certain temperature.
it makes sense that a coiled wire would produce more heat than a straight one. The coiled wire of the same length would be in a much smaller area and reflecting heat off each coil to the next. Easier to raise and maintain temperature.
So in therory the smaller you wrap the coil wire the hotter it will become with the same amperage.
The next step would be to see how small one can wind a coil and still get a wick through.
if it gets to hot you could raise the ohms and get the same vape and conserve battery power.
