Here is a thermoelectric peltier cooler module coupled with modular heat sink with two fans – making ice super fast. I have used rubber bands to keep the peltier in place & to support the thermometer probe – used ordinary heat sink paste – No copper slabs, No thermal glue !!! ;) Better cooling characteristics can be achieved with the introduction of a copper block/slab between the hot side of the peltier module & the heat sink surface. However, the purpose of this video is to show what can be achieved even without a copper block/slab. ENJOY THE VIDEO FOLKS !!!!!………….Please feel free to comment & make suggestions. LONG LIVE SCIENCE !!! ;)

@prodigytechus, you just put water on the cold side such that the peltier forms crystals? I am currently working on a prototype room air conditioner project and I am looking for materials to build a suitable enclosure for the cold side to concentrate its cold and its density. I propose building a cubicle out of styrene foam. Any suggestions?

@PUNKROCKINTHISSHIT
You can apply it ANYWHERE where spot cooling is necessary – CPU, GPU, Laser modules, IC’s, portable devices etc etc etc.
Use your imagination !!! :)

what exactly is this applied to? and do you suppose you could apply it to cooling a computer’s Cpu/Gpu.

@doynick
It isn’t very efficient at generating electricity too – you will need a hot side at one end & a real cold side at the other to cause any meaningful flow of atomic vibrations (heat) and produce useful amps at a meaningful voltage.
Plus, using a TEC is further inefficient, a TEC is a Thermo Electric Cooler, its not designed for generation. You need a TEG, Thermo Electric Generator (again inefficient). But, experimenting is GOOD !!! just know the disadvantages and advantages :)

@prodigytechus
Thanks for your reply. If thats the case, I think its better to use my
thermoelectic as generator instead of cooler.

@doynick
It isn’t enough to cool you car & it isn’t efficient too even if you invest in 500W peltiers.
Get a better air conditioner if your present one isn’t good – remember, peltiers are not for bulk quantity cooling, but for *precise* cooling solutions ONLY.
Remember, ONLY for PRECISE cooling, where cost & efficiency are sacrificed for precision cooling and performance.

@NetJunkDumpster
A 121 W peltier (consumption), actual cooling wattage is about 30W.
However, mere power ratings are useless unless you are not interested in precision & deep engineering. You should NEVER bother about electrical wattage – but think in terms of voltage and current rating.
Never bother about thermal wattage but think in terms of Thermal potential (deg) and joules (analogous to current). That’s the correct approach to true engineering.

Im planning of using this TEC as a replacement of my car’s aircon. Do you think its enough to cool my car? My idea is to pump the cooled water to evaporator while the hot water will be pump to the radiator for cooling.

how meant W is that TEC?

That small a space?……Go for the peltier. However, you need big peltiers if you want rapid cooling, but then you need bigger heat sinks.
Or are you willing to use water block cooling?

i cant see anyone making a small drinks cooler for the car as the compressor itself is twice the size of a can of beer plus u then got the copper pipes etc.i wanna us a peltier as i have more than enough power in the car for it and i need t to be small so it doestn take up much space.a peltier is perfect of the job if i can get it cold enough which i think i can because of your explantion which is greatwhat else would you suggest i have space about half the size of a normal glove box space.?

Is it that you want to make a drinks cooler using peltiers because you love using peltiers or is it that only because they provide cooling?
I am asking this because – peltiers are very very inefficient, you’ll waste too much money & battery power powering your peltier based cooling device. Its cheaper & more efficient to use the regular compressor based mini coolers you get for cars.
Best Wishes

im impressed thank you very much for the explanation. now i can get to work on making the drinks cooler in my car i have a perfect space in my car for a big massive heatsink and fan which should keep the hot side cool enough to produce _ minus degrees on the cold side. any other projects you have done i make stuff all the time and just dont have enought time in the day to get all my projects finished.
thank you

You see – all that the peltier does is transfer heat from one side to the other & maintains a fixed temperature difference between the hot & cold side depending on the voltage (also current consumed).
So if you cool the hot side, the cold side gets colder to the extent of the temperature difference.
Say the temp. difference maintained is 50 deg centigrade. The room temp. is 25 degrees,
so if you manage to bring the hot side to 30 deg using a heat sink, the cold side will get to be -20 deg

whats the raing of the peltier because i have a small one and its not cold enough for freezing i dont think i tested it agin today bit dont have a thermometer ??
thanks for replying

Pretty simple buddy!!
Peltier module + Heavy duty heat sink + 2 fans (serial air push-pull config) + Heat sink paste/Thermal glue.
Hot side coupled to the heat sink – cold side used for cooling…….

how did you make this because im researching this at moment ive finally got some time and wanted to start maiing a drinks cooler for my car.i found you vidoe and wondered how you made this as it freezes water etc ? please reply thanks
