Bit of a thought. How about other thoughts on peltier cooling systems on the intake pipes of our intake systems. We are talking 50 degree drops from ambient. My only concern is the amount of airflow thru that pipe. For some reason being cold came up when I was thinking of spending next week in Norman Wells, Northwest Territories, CA .

interesting idea you have there, like cooling the heat sink on a microprocessor..... but dont those things draw massive amounts of current to make it not worth it? :?

Takes ALOT of power to keep 'em working at their full potential, plus the gains might not be worth the costs (mainly labor). I see where your going with this, but I personally wouldn't recommend attempting it. Many other options to decrease intake temps.

What is it?

Peltiers are probably used in many industrial scenarios, but to most people they are for extreme computer cooling options. Mostly supercomputers, but some people use them for personal use when overclocking their CPU'* mad-style. One side gets VERY cold and the other gets VERY hot.

It still intrigues me. Cool the air charge AND intercool it. Right on. Current draw isn't too much of a concern, I've already got nutty power reserves for my friggin' audio habit.
It is good to hear other folks thoughts though.

like a heat sink on the pipe? Would that work?

My biggest concern would be the velocity of the air. To put it simply, would it even have an effect on the air temp.? Maybe somebody could give a thought off the top of their head. Otherwise, given it may take some time, I'm going to try and get our Solidworks junkies at work to due a model for me. God only knows how much beer this will require.

How would you use the peltier? Would you attatch it to the pipe? I don't see how you'd incorporate it. Airflow isn't a problem, the velocity is not our #1 issue with intakes. Laminar flow of high velocity is the biggest. If you have too big a pipe, you're loosing HP.

A heatsink won't do much, because there'* not too much heat really in the pipe. Making it colder then outside temps is what'* really beneficial. Thourough shielding, and good induction (ram air, etc) will be more effective then any heatsink. The heatsink would be warmer on the engine side too, actually heating up the pipe.
