Hi all, some background info, thanks for reading and helping!
I'm working on a project, the portable device is to vaporize glycerol(300 C). In an attempt to maximize vapor production, I've decided to skip the experimentation and calculate the optimal specs for each part. Also pardon my vocabulary, computer science major with about 5 hours of research done in resistance heating and general electrical engineering.
These are the limits on the circuit board:
PWM (Pulse Width Modulation) output, up to 5 amps
Variable Volt: 3~6.0V
(2) 1200mAh 18350 batteries
1.2ohm minimum coil
20mm maximum length of coil
My goal is to create a heating coil that will vaporize as much glycerol as possible on this board. I did some research and people say the lower the ohms the more heat is released so is it safe to assume we should stick to a 1.2ohm coil? We also want it to have as much surface area as possible, to heat up more liquid. The preferred heating wire is 28awg Kanthal A1. We also need the coil to reach the desired heat relatively quickly(0-2 seconds). So would it be better to use a lower gauge wire so we can put in more wraps and get a longer coil? Or should I stick with the common build of 10 wraps around a needle for around 1.5ohm. What would be the best coil design and wire material and wire type(round vs ribbon/flat).
Cheers,
Eric
