peltiers on IC possible?

[loreak]

I thought it would be interesting to see if you could put peltiers on the top and bottom and sides of the intercooler and u could flip a switch to turn them on...screw the bag of ice idea just use peltiers.

for anyone who doesnt know what a peltier is, for cooling processors in computers a while back some people used peltiers, u run 12v through it and one side gets super cold and the other side gets really hot. Well you would put the cold side on the processor and the hot side u just had a fan blow away the heat.

If you could line the top and side of your IC with it and have a switch you could flip, its totally run on electricity and temperatures get super cold like as low as -50 etc.

I dont know how it would work in reality but i thought it was a kewl idea. Im sure you could at least turn it on before runs while waiting or inbetween runs and cool the IC down signifigantly.

I posed this same question to my Chem Professor several years ago and here are the problems he pointed out to me.

Compared to a CPU, a FMIC has a lot more mass to cool down. The power requirements to run a peltier on something that size will require a lot of power. And the other point to consider is there is also a hot side to the peltier. You will need a heatsink big enough to dissipate all the heat being drawn out of the FMIC.

But all in all I think it is do-able...... just not worth all that trouble.

:rolleyes:

do you even know how much amperage and wattage it takes to run a even small peltier? please find more realistic ideas.

One way that peltiers might aid is with air to liquid intercoolers. If you would take a longer block of aluminum and mill a snaking channel or groove (about say 1/2" deep into the block) and then drop a mating aluminum plate on top of the block (sealed to the block of course), you will have made a nice water passage. Now secure pipe fittings at the ends of the block, throw down some thermal paste and a few peltiers/heatsinks-fans on the top cover plate and your water snaking through the channel gets cooled (the water that either heads toward the IC or reservoir).


I wouldn't mind trying it out to see if it's practical, wouldn't cost too much and should draw around 5-10 amps, depending on how many and of which size peltiers are used. Would be interesting to see how much (if any) your intake temps would drop.

i said it was just an idea and i dont know how it would work in reality ass

[RippinGSX]

It would be cool if it could be done efficiently and effectively. Just think of it.......Energizing IC captain...........:D

[Stephen]

HEHE, that would be quite funny. I always wondered about welding heatsinks on the endtanks.... I wonder if that would help at all?? Have the heatsink sticking down under the bumper catching some air....

I think you should use Liquid cooled intercooler, And For the Heat echange for the liquid, Line it with pelters, and put heatsinks on the ends, It would be Alot better then a Radiator Type Heat Exchanger and it would be cooler. I think you might wana check out overclockers.com and read there Extreem moding stuff, Pritty cool. heres a IMG i made in Paint really quick What I think Would be a Great system. and cheep.http://www.imagestation.com/picture/sraid74/pb14ee59030a9b88e329c403a60d9f309/fb6247d8.jpg

Loreak,
I've been thinking about that for a long time, it's a great idea indeed, don't worry about the people that made stupid comments, they never overclocked a CPU and never even felt what a small piece of ceramic called 'peltier' can do.

And they used to sell it is various sizes, too.

Too bad my FMIC is top-to-bottom and there's not enough surface to mount them as it would be for a side-to-side...

But I fully support your idea, let me know if you ever try it.

Running the peliters would take more energy from the car than would be produced by the cooler intake temp.

[doug]

Huh?

[PogiTSI]

Obviously no one has delt with peilters.

[James92TSi]

All a peltier does is move energy from the cold side to the hot side. You still have to have a heatsink and good airflow on the hot side in order to get cooling on the cold side. All you're doing is introducing another transfer agent (the peltier) into a system with the same cooling capacity (ambient airflow across the core) that it already had. The only difference I see it possibly making is cooling the IC down more when off-boost, similar to spraying water on the IC before a run. During a pull, it would not make any difference in cooling IMO, since the ambient airflow across the peltier heatsink is the same airflow that would have been contacting the IC directly. The peltier is just a middleman in this case.

Then you have the electricity requirements. This would be one large heap of peltiers to cool an entire IC... is it worth it? Peltiers aren't cheap either.

here is what i did. i have water injection, one nozzle right after the turbo, one right before the throttle body. i have a manual override switch, so i can activate the system when not under boost. if you touch the pipe coming off the turbo, it is hot to the touch, if i rev the motor, and activate the wi, the pipe gets COLD in seconds. you can reach down and feel in intercooler inlet tank, and it will be warm. rev and activate, and it gets cold in seconds. the whole intake gets cold. all the pipes, intake manifold, etc. this is the AIRFLOW cooling the pipes and intercooler, which is a lot faster than cooling the intercooler, and having it cool the airflow. add in some methanol, and it cools even more.

[PogiTSI]

ok, put the peltiers in the trunk, and heatsinks on the hot side of the Pielter is enough. Though Peltiers are NOT efficent, They take ALOT of power for something so small. The CO2 from DropZone is a better idea, Co2 is cheep, and more Available then the Nitrious Oxide.
