Welcome to ECF, buck...
I've interpreted your build to be a:
- Single 0.3Ω coil.
- 24 gauge/8 wraps/.511mm (.020") mandrel.
- And what I figure, based on the photo, a net leg length of 6-8mm.
- Using a 18650 unregulated mod, with a discharge @ 4.2v of 59 watts.
This correct?
If it is, your problem is not wicking, but rather a ridiculously high heat flux of 868 mW/mm² - which is about 400~500 mW/mm² higher than most RDA fans. "Heat flux" is the radiant coil temperature, expressed as milliwatts per millimeter squared.
As you can't independently adjust the wattage output with a unregulated mod - but only control output with resistance, you can't lower the wattage if you remain at 0.3Ω, to obtain a lower HF.
If you reduce your wire gauge to 21 gauge, build a single 0.3Ω 10 wrap coil on a 1.19mm (3/64") mandrel, you can lower your HF to 306 mW/mm².
Options at 0.3Ω:
- 22 gauge - 433 mW/mm².
- 23 gauge - 613 mW/mm².
- 25 gauge dual parallel coils - 307 mW/mm².
- 26 gauge dual parallel coils - 435 mW/mm².
Use both Steam Engine and the SE user guide -
found below in the sigline links - to optimize your builds a balance of gauge, resistance, surface area, wattage, heat flux, heat capacity and leg power loss.
