what is the link to buy that specific type of large heatsink you attach the fan to? The heat sink you provided a link for will not allow airflow through it to the panel and sink below it

Additionally, I have found circular heat sinks, but none with the round copper plate attached, is that something you purchased separately and attached? Or were you able to buy one with it already on there? Thanks!

Some of those circular CPU heat sinks have a copper middle and some of them are just aluminum. depends on which one you get, when it was made, and what company you buy it from. I can't tell you which companies sell which. The ones with the copper slug in the middle, cool a little better but not by much. most companies just make them completely aluminum to cut down cost but if you find one that has the copper slug in the middle you should spend a little more to get it if you care about performance. The best thing you can get are CPU heat sinks with heat pipes because the copper heat pipes spread out the heat to the fins more evenly and quicker. If you want to spend more money and/or are doing this for a permanent project, you can get AIO units with are cheap and easy water cooling devises which work a little better than the air cooling setups and are generally easy to install.

RCLifeOn donkeys

RCLifeOn is my favourite video

Did you know that steel has a very low thermal conductivity?

Since I'm seeing this after 5 years. I'm give some context. Most of the point of heat in a dehumidifier is to expand the air, which makes the existing vapor spread out. Which allows the air to absorb additional moisture from surrounding air. (Like a vacuum for moisture.) Then when it hits the cold, it then loses that extra space. And so the water is pushed back out of the air. Along with additional moisture it might have at ambient temperatures. I don't think those screws have much of an effect on efficiency. Plenty it's already wrong with it. IE using peltiers to begin with... there should be some space between the hot and cold radiators, which you can't do with peltiers. And they already use a lot of power, for what they do. (I'd argue that most home dehumidifiers are made too compact. But that's me nitpicking.) This though, is good for learning how things work. And a fun project you can do on your own... without learning how to hook up condensors.

​@@josholin31 that's... Not how dehumidifiers work...

@@platinumsky845 I checked what I typed. Are you misunderstanding it?

@@platinumsky845 "A dehumidifier works by drawing warm air currents into its coils via a fan. The warm air contracts as it's fed through the refrigerated coils of the machine, and condensation is left inside the dehumidifier." straight from Google, that is exactly how they work lol.

I know right

he should watch linustechtips linus shows the correct way to use thermal paste

well i like his content (apart from the ads) 40% of the video runtime is sponsor ads that have nothing to do with the video

The additional amount of thermal paste is to compensate for the lack of pressure being placed on both heat sinks, where in a computer, the heatsink mount puts pressure on the CPU and heatsink, spreading out the thermal paste. EDIT: Just watched the entire video, I though he put two pea sized blobs, not a freaking giant blob. That is too much thermal paste.

Thanks for watching!

That's the major downside of Intel stock cooler. The fan blows air into the heatsink instead of blowing it out onto the surroundings. And also it has small surface contact. So it doesn't transfer the heat very well. And he's putting way too much thermal paste in it as well. You could try to grab one of those heat pipe based cooler like deepcool ice edge 200M ( the only cooler I know that heat pipe based ) for the hot side so that it'll has less interference with the cold side...

@@atalakeanumonarshi129 You know you can just turn the fan around, right? I've done this on a few personal PC builds and it works as well if not better than the standard arrangement.

Or install a drainage tube that leads to a wasteway. No need to remove and service the drip pan that way.

Hey thanks! I connected the LED lights, peltier chip and the electric fan.

How? How do you maximise the water pull?

@@japreet_kah build 50 of them :)

Thanks for commenting :)

Thats wat it is 😂🤣

You are not the only one who has thought of that. When you live in the desert you start getting creative

Ponerle paneles solares en lugar de la bateria

You can use a freezer powerd with solar to cool water down, pump this water with an electric water pump through cooperpipes (outside of the freezer in a shady place) and back in the freezer. Through this circulation, colling water down, pump it through an cooperpipe outside of the freezer, back into the freezer and if you manage to finde the perfect pumping speed and freezer temperature, you can create water drops on the surface of the cooperpipes, collect them and you have drinkable water.

There are thousands of dehumidifiers on the market. To condense more water using less electricity you would use a heat pump dehumidifier not a thermometric dehumidifier. But even with heat pumps you will still needs A LOT OF ELECTRICITY and it will not work in COLD places.

peltiers are WAY too inefficient to be used as an air conditioning device.

+Prashant Sharma Awesome, thanks for watching!

Sorry, I have no data regarding performance. I scrapped the project due to the inefficiency.

I looked into it a little farther yesterday and determined that the cost to build a dehumidifier using this technology would be at least 10 times the cost of a consumer level dehumidifier with the same performance. That aligns well with the inefficiency you mentioned. Thanks for posting.

@@RcLifeOn hello, i was wondering if you came up with a more efficent model i would like to run off a solar pannel and only need to collect approx 100ml 1/4 a pint in 24 hours

@@Marc9889 hello, i was wondering if you came up with a more efficent model i would like to run off a solar pannel and only need to collect approx 100ml 1/4 a pint in 24 hours

1/5th or even 1/10th of what he used would be better tbh.....

There are heat sink compounds that also works as glue.

No it doesn't work

12 volts?

hot side, you want the hot side to be cooled as best as possible

Is there a heatsink on the hot side? A peltier cooler will not work correctly without a heat sink. By the law of conservation of energy, you cannot remove heat without moving it somewhere, in other words, you cannot get one side to become cold without pulling enough of the heat away.

dehumidifiying means taking out the humidity by condensing the air the water droplets that formed means its a dehumidifier

there are a few flaws in the project: 1: the peltier is not coller properly, the round cooler surface does not cover the complete square surface of the peltier, making the peltier run warmer and become less efficient. so make sure the cooler covers the complete surface of the warm side of the peltier. his can be solved by attaching an alluminum or copper plate between peltier and the round cooler. 1.1: use a bigger heatsink on the hot side, the more heat you are able to get rid of the more effiient your peltier cooling. so use a CPU heatsink with at least 95 watts of cooling rating. 2: even if you cover the complete surface of the peltier, the peltier may actually be to cool for water condensation, instead the water drops may freeze. one possible solution would be to increase the surface area of the cool side or attach a small fan, to keep the cool side from freezing but maintaining a minimal temp. to allow condensation p.s. make sure you don't make the cool side to big either, in that case you may not achieve the condensation temperature. 3: allign the cooling alluminium finns in vertical position. gravity is going to help you to form bigger drops, which are going to run down faster and allow more surface to exposed to the cool side. (accumulation of water drops works more or less as an insulator and keeps the moisture from condesation on the cooler). 4: use a power supply for the Peltier., batteries are sometimes to wea give enough current in order to power the system properly, and if the do, they will be dry after 10-30 minutes and need to recharged. thefore not the best solution if you want to power the system for more than 1h. use a normal 12V 6A power brick that should cover the most common peltiert types (such as 12706) and their required cooling. 5: peltiers are ineffizient AF, it's cool as a learning project or to make your own small DIY fridge etc. but they are really ineffcient. and if you use cheap peltier elements then they are even worse. but for learning they are awesome! 6: humidity. if the humidity in your room is low but temperatures are high, then your little small peltier dehumidifier will not work. its because the relative water content in the air is low. instead if the temp. in the room is low and the humidity is high then you are able to condensate a lot of water. but in generall, the higher the moisture in the room the better works the dehumidifier, but also the higher the risk for getting mould ;-) 7: thermal grease: thermal grease is primary made to get warm, not cold. it becomes more rigid when it cold and is less conductive. looking for special thermal grease which supports up to -20°C is one way to make it more efficient. the hot side is not an issue at all for the grease hope it's going to support you in your future projects!

Mads Bekker this is depends upon the RH value.....

Thanks dude! It will work fine, though you probably need a bigger one if you are gonna use it in big rooms.

the higher the humidity the more effective the condensation, the more water you are able to get from the air. but this construction has a few flaws. 1. Battery powered, the LiPo is expensive and difficult to handle 2. the peltier is very inefficient when it comes to cooling but is awesome when you don't need massive cooling power, as well when you lack space 3. use a simple 12V 75W AC adapter to power this thing;-), the most common peltier unit (12706) uses 6amps of power better buy a normal dehumidifier at the local hardware store or even better a transportable air conditioner. i use a suntec in my apartment when the moistiness is breaking the 85% mark and it really sucks the water out from the air.

It doesn't change the temperature, it only removes moisture from the air.

short, unfortunatelly. the battery he is using has a capacity of 11,1V*2,2Ah=34Wh, the peltier consumes between 40-60w per hour, thefore the battery is going to last between 20-45min use a 12V 6A power brick instead. cheaper than a battery and way easier to take care of. plus you can run it for muliple hours without worring about the current state of the battery

Sorry about that! Place a piece of paper or plastic container underneath to collect the water.

Heat is moved from the cold side to the hot side, so the difference is zero, if it was 100% efficient, which is impossible. In reality, electrical resistance adds additional waste heat, but that is basically negligible.

Is it better than old compressor cooling systems?

nope. peltiers have roughly half of the efficiency of compressor cooling their benefits are: no moving parts and their small size

Jag brukar köpa från detta ställe: www.epp-versand.de/ Dock är det depron och inte foamboard.

You can look at it two ways, it collects water from the air or it removes water from the air. Basically it could be a cool device in certain situations where you need to find water, or if you wish to remove water in order to "dry out" the air.

peter allridge These modules are almost indestructable in that regard.

Outdoor humidity is often too high. Optimal relative humidity is said to be between 45% and 55%.
