Problem of hot attys solved?
When you are chain TC vaping and the vapor (and flavor) starts to drop off. This has bugged me for years. The hotter the atty gets, the less vapor and flavor it produces. If you guessed this is a wicking issue not keeping up. Yes it sounds like it until you add the same tank on a SXmini SL Class keeps up just fine.
For example, I noticed this first with an Atlantis EVO tank with a Triton 0.15Ω Ni200 coil head. I'm sure it was happening even much earlier. But on a DNA mod, the EVO tank gets hot very fast while chain vaping. With a Legend/X it takes much longer to get just as hot. And on a YiHi SL Class, it never seems to get the atty really hot. The YiHi makes sense since it isn't firing 100% of the time with PWM. Not really sure why the Legend/X is better than the DNAs in this department.
Then I have noticed that RDAs and tanks that doesn't get warm much doesn't experience this problem. Like the cooler the juice is before it reaches the hot coil, the better the vapor and flavor will be. This probably explains why RDAs has very good flavor and vapor. As you drip room temperature juice on the coils which cools them very quickly and the juice doesn't get very warm at all in the process. And then you fire that coil and it is so good!
This got me thinking that maybe the board doesn't play a major part in this, maybe it is how well the mod acts as a heat sink. The largest DNA mod I have that would act as a great heat sink is my HOG DNA400C. It's like a pound of aluminum with a heavy SS 510 mounted on top. I threw a tank that gets hot on it and chain vaped away with TC. And it is performing very well. I can't get the tank hotter than lukewarm. The SXmini SL Class mod is a tube mod which also works well as a heat sink.
