Atomizer gets Hot

[DiscoPotato]

Hi guys,

Is it really normal for an atomizer to get hot especially when using dual coils?
I just created a dual coil a couple of minutes ago using 24 gauge kanthal wire, 10 wraps each on a 2.4mm precision screw driver. My meter shows that the resistance is at 0.4 ohms, being curious and all since this is the first time that I made a dual coil, i decided to test it out.
Got some good flavor and vapor, though the vapor is warmer than I would want it to be ( I prefer cold vapor)

After taking a couple of 5 secs drag, I notice that my atomizer became hot, not warm, but hot. Is this something that I should be concerned about? I am doing something wrong or have I done something wrong when creating my coils?
Please help.

Here are some pictures of my device and atomizer. ( Philbox wood mod running on 2 pcs of AWT 18650 2600mah battery, my atty is Haze by vapehead origins)

by the looks of it, your atomizer doesnt really have any heat fins. And if your airholes are small, the airflow is not enough to cool down the coils. The power that goes to the coils turns into heat and if there is insufficient cooling for the heat dissipation, then .... gets hot.


you're also subohming on a mech right? You are going to get warmer vapor and stuff is gonna get hotter. If you're inhaling slow then theres not enough air passing over the coils which also lead to ur atomizer being hot. There COULD be something else but those are the usual culprits for me.

Some do. My Silverplay has huge heat fins, but it gets hot. My Orchid never did though with the same build. Both have good airflow.

Personally, I would use more cotton than what you have in there. Also, more airflow will lessen the atty getting hot.

Yea, your only pulling 50 watts at 10 amps ,you basically put a small space heater in the volume of a walnut,

Thank you so much for the answers. This be my first time to work with a dual coil so please pardon my ignorance. And as mentioned, aside from increasing the amount of cotton on my coils, would it make a difference if I increase the diameter of the coil from 2.4 to a 3.0 mm?
Would really look forward to more suggestions and tips. Thanks.

higher resistance coils will pull less watts so yes to your answer. increasing the amount of wire you use will increase the resistance of the coil, which in return will lower the amp draw from your battery and result in less heat dissipation.

for mech mods, just remember:

more wire = higher resistance (ohms) = cooler vape
less wire = less resistance (ohms) = warmer vape


i know this is a forum to learn, buttt, just for safety reasons im putting this out there, if you dont understand the capabilities of your batteries/mod then you should probably look into that. Knowing the capabilities will prevent lots of headache and injury if you do something wrong. Make sure you know the lowest build your setup can handle otherwise you're going to be diving into dangerous territory. It just seems to me like you need to inform yourself about ohms law.

something like this is what you want for sub ohm and dual coils see the big air holes and also the drip tip has a coating so it wont get hot alot of the sub ohm dippers also put a plastic sleeve for the drip tip for the same propose. You can drill your current air holes bigger or get a atty alreade made for sub ohms. I prefer none contact coils my self I think they get hot quicker and dont generate as much conductive heat.

edit: 5 no contact wraps with 28 guage dual coils will give you some nice clouds with alot less heat build up.

This is exactly the atomizer that I have sir, the Haze from Vapehead Origins. The one Im using is the one where you can put a drip tip on and the one which has a built in metal tip covered with a plastic on the chimney like mouthpiece tube.

well you have the right atty ;-) I think you are making your coils with to many wraps try 5 wraps as I said I like no contact coils you have to do a little more fiddeling to get them spaced right but IMO they are better than contact or micro coils.

I could surely fry an egg on any one of my drippers. Just need the worlds tiniest eggs, LOL.

 

[Thrasher]

Even with adjustments dual coils are hard to keep cool, should have seen some of the quad setups about a year ago you could practically see the metal start to get soft lol
Lots of airflow is all you can do

 

[Bunnykiller]

ever consider going to 28 or 26 ga.? thinner wire requires less energy to heat up, thus resulting in less overall heat production.... ( and your batteries will last a bit longer too )

I think a few people in here need to learn a little (lot) more about ohms law...and thermodynamics / thermal conductivity. I've been around for...well, a little while and I've honestly never seen so much bad advice and misunderstanding in a single thread, ever.

I can't even be bothered to sort you people out because I am 100% convinced the vast majority of you won't listen due to vape-egos.

What I will say is this; To OP: Yes, your atty should get hot...this would be very normal under these conditions. Also, please please please please please learn ohm's law like the back of your hand. Then read a bit about thermodynamics, battery chemistry, safe battery use, etc...The life you save could be your own...literally.

Please lend credible assistance rather than recommending a 4yr. degree.

Are you even sure The Vaping temp comments come from a Hot vape or might it even be in comparison to a preference of say.........Hookah Vapor.......

He didn't say anything about a 4 year degree, but is saying anyone doing rebuilding should know the basics, and isn't that what we tell people all the time (or should be anyways)?

 

[Vatigu]

heat capacitance of 24gaugex20 wraps 2.4mm ID is going to be very high... even when the coil is no longer powered it still bleeds that heat to the posts and warms the atty
75.53 mJ K-1 That is a very high number
I assume this build takes a while to "fire up" that is the coil storing heat as it's produced before finally hitting boiling point and evaporating the heat production away. Even after you stop pressing the button this 75.53 mJ k-1 needs to go somewhere.

Who said anything about a degree? A person can learn ohm's law backward and forward in a weekend if they put any effort in at all. I think you're thinking about an electronic engineering degree which is...well...NOT ohm's law.

Your cynical reply and foul attitude are the exact reason I'm NOT going to make a more thorough post in this thread. Because people like you think they know everything and that someone with less posts than them is clearly inferior and not to be taken seriously.

 

[Rule62]

Looking at the build, I'd have the coils closer to the air holes. They appear to be close to the center post, but fairly far away from the air inlets. Generally, the farther away the coils are, the harsher the vape will be.

Nice to see even the simplest of questions can result in a brawl....

Its going to be a little difficult to get a cold vape from a dual coil RDA. Buzzlove gave some good advice. Spaced coils and a .28 ga wire will reduce the heat some. A really long drip tip will cool it off too.
Big airflow. The harder you draw, the cooler your vape will be. More air=less heat.
