I intend to experiment with a racing automotive use for Peliter cooling and have some questions.
I will be attempting to use/integrate Peltier plates into a system to cool automotive engine coolant for a specific purpose.
My question is in reference to the ambient temp issue. I will be using Peltier coolers to attempt to cool fluid rather than heat it. (opposite of a water cooled CPU). Coolant comes out of an engine far above ambient. And ambient could be as much as 110 degrees with <5% humidity.(I live in Vegas. Please to not pry as to what/why exactly I am doing this and/or it\'s benefits, this is for racing and not for actual engine coolant. It will be mounted in the front of the car with lots of airflow...although variable outside air temp for use in all the hotter states)
Now, with the coolant being +- 200F and ambient being, say 90F, can Peltier coolers work better than just a radiator by itself. I wish to integrate P-coolers into the structure of a radiator and/or a seperate structure post radiator through something like a CPU water cooler, where the pipe gets flattened widely so as to promote maximum surface area for heat absorbtion. (kinda like a \'cool can\' that is filled with ice with a fuel line coiling through it for cooling fuel for a race car).
Is a peltier worth it in your opinion?
What high energy/high performance manufacturers do you recommend?
I am most likely going to use several 4x4in plates to make something three rows, approx 16in long x 4in wide, 4 plates per row, with the coolant making 3 passes before exiting. There will be LARGE heat sinks (think automotive audio amps) and large fans (think 2 motorcycle radiator fans)...
Any pratfalls you can think of right away?
Ambient too high for any gain in cooling performance? |
