Can you elaborate on the hybrid part? That makes absolutely no sense to me. You're saying there's no such thing as hybrid heating? Then what is the Mighty/Crafty/Arizer Air/Fury doing? They all claim hybrid and we have evidence that they are hybrids.
Sure. From a scientific POV (not a marketing one.....), there can be no such animal. That's not how Thermodynamics works. 'Follow the heat'.
In a convection vape, super heated air enters the load at substantially higher than 'magic temperature' and
cools as it gives up heat energy to the load (warming it and eventually making vapor as it gets near 390F). IIRC the maker claims something like 700F on low? This is, however, not a fixed reading since the harder you pull, the cooler it gets? With no flow you can see a glow in the heater that indicates something like 1300F.
The key is the hottest thing in the vape is quite hot. It has to be to heat the air to hundreds of degree hotter going in than coming out?
This means unless you sense the actual air temperature somehow, and also the flow rate, it's impossible to display the actual delivered temperature?
Regulation to a fixed temperature is also
just not possible. Unless you can foretell the future, of course. If the vape has such a feature like display of working temperature or temperature regulation, it can't be Convection based.
With conduction, OTOH, the hottest part is the cup/oven body. Everything has to be cooler to satisfy Thermodynamics. There is no way to heat at substantially hotter, nor any way to regulate the effect of the super heated air. If you did something clever, like put a second heater in running at a higher temperature to heat the air to several hundred degrees above 'magic temperature' (which nobody does?) before introducing the air to the already preheated (by conduction) load you'd get
instant combustion..... Every time. Them's the rules.
Many of the sellers who claim Hybrid technology are using more preheating of incoming air, but as long as that air is below 390 or so
it's simply preheated air, it makes no vapor! It simply 'robs less heat from the load than otherwise it would. Again, to produce vapor it needs to be hundreds of degrees hotter than it can possibly be if the hottest part of the heater system is much cooler than that. That's the way heat really works, 'flows from hot to cold'?
Heat soaks are a good clue. If the vape benefits from them it's because extra time allows more heat to conduct in to replace that lost from the previous hit. If, OTOH, a longer pause between hits lessens production on the following hit it's a Convection effect, the load having cooled off due to no conduction in but rather out of the load, the load is cooling. This is heat that the heated airflow must replace before further heating and vapor production can happen. Pauses in Conduction mean less, not more, vapor immediately available on the next hit. One or the other?
Claiming Hybrid technology no doubt scores big points in vape marketing, folks take it at face value as a positive feature and lay their money down. And under the tough and tumble rules of marketing ('first liar don't stand a chance'....), once one maker claims it, the rest are under serious pressure to jump on or lose sales. The Suits can be depended on for such things, it's their job? But doing so and insisting it's really happening will get you flunked out of a serious Physics class in short order. It's not only not happening in real world vapes, it can not. Follow the heat......that's what Thermodynamics is all about.
Please, if you will, tell me what's behind "we have evidence that they are hybrids". What is this evidence, and what do you believe is behind it? TIA
Sorry to ramble, but you asked.....
Regards to all.
