Coil diameter and amount of wraps

[tljnfo]

I know this might be silly... We are curious about why the hell certain things work the way they do on a very small level. We don't necessarily need an answer involving individual electron behavior but... The smaller and more specific the better. Here it goes:
Say we have 8inches of 24 gauge kanthol wire (or any amt really). The point is, given the same Guage and same length of wire, what effects exactly does the variance in amount of wraps/coil diameter have on vape production? Why does a nanocoil burn hotter than a microcoil??? We have read so many answers to these questions and none of them really satisfy our need for specificity. Please help us out! If you don't know about particle physics, we would appreciate your input anyways. Thanks!

hi @tljnfo, I found this thread to answer : Nano coil vs Micro coil, is there a standard definition? | E-Cigarette Forum

Welcome tljnfo I'm no Einstein or Stephen Hawking, but from an observational perspective, I'm going to suppose that a nano coil (in my definition < 2mm diameter) typically might be compressed, so there's less airflow around the individual wraps of a coil. A micro coil (larger diameter) might be wrapped with space between the individual wraps, so there's opportunity for more airflow to cool the individual wraps. Also, you're going to have more wicking material (thereby pulling more juice) which could also lend itself to keeping the coil cooler from a temperature perspective.

NONE of this is scientific, by any stretch, but just visualizing, I could buy into that kind of logic. I'm probably dead wrong, but it's my story and I'm sticking to it.....

Welcome to the forums!

More wraps vs less at same OHM?? Difference is Heat concentration and wicking.

I wonder if somebody still uses nanocoils.

A nano-coil will be compact and tiny taking more wraps (we'll say 1.5mm or less in diameter)(inches of wire we are talking about, resistance increases more wire is present) and have more surface contact to the wick and liquid due to the length of the final wrapped coil, such a compact heating element, inner wraps will be hotter than the out wraps, and heat will transfer, in essence making a heating tunnel, down side, a lot of times these nano-coils will dry out or get choked for juice wicking very quickly.

A micro-coil (1.5mm to 2.5mm we'll say internal diameter), to reach the same resistance as say the nano-coil above, would take less wraps, still using close to the same amount of wire in beginning length, will have less surface to wick and juice contact persay, but with the proper amount of wicking and airflow can produce just as good if not better flavor, but also in my experience more vapor due to the airflow and heat flux.

A macro-coil (3.0mm and above internal diameter), to reach the same resistance as both the nano and micro above, will again use less wraps still using roughly the same amount of wire, cloud chasers especially love macro-coils due to the amount of wicking that can flow more juice quickly to the coil, airflow needs to be even greater than a micro-coil, flavor is reduced due to less concentrated surface area contact with wick and juice, but they vaporize juice rapidly, more juice vaporizing, the more vapor produced.

In essence that is a little layman description to give you a better grasp I hope.

Yup, the smaller the diameter, the more wraps which means more surface area to the coil

How so?
The same length of wire = the same surface area. Does not depend on coil diameter.

I do.... in my RSST 26 - 28 ga. wrapped on a sewing needle 10 -16 wraps

You know, your right lol. I was thinking about something else when i answered and preoccupied with getting away from work, good catch.

I use traditional spaced coils anyways. Never a dry hit from over drying the wick

 

[Bunnykiller]

Yup, the smaller the diameter, the more wraps which means more surface area to the coil

hows that when the same length of wire is being used? lets say its 3" of wire used in both cases... the surface area is the same on macro or nano coils

 

[Matty316]

The differance between nano/micro coils and spaced coils or coils with a larger diamiter is their efficiency in producing heat.
A nano contact coil may have the same surface area but is more compact so heat is transfered and distributed more efficiently throughout the coil. Because each wrap is touching and the diamiter of the coil is smaller the heat from each wrap is helping more to heat the next wrap and the next and so on. So the ramp up time is quicker and so less power is needed to heat the coil.
