Cooling Air Pipes: Questions and Answers

[rlingineni]

I have a automatic air pump like this one(http://www.thatpetplace.com/silent-air-x-5-air-pump-80-gal-2-outlets) and pass it through a metal pipe, while the metal pipe is cooling at 32 degrees and the air within the pipe cools and goes somewhere and then that same pipe(no breaks anywhere) loops back and releases the cool air back into the chamber where the original pipe passed through for cooling. For some reason the pipe feels warm, is it supposed to do this? How may I get it cool again? Also, if two masses of air at the same temperature collide what will happen?

"goes somewhere"? Like through a heater...?

Are you accounting for the heat added by the pump?

 

[rlingineni]

Going somewhere refers to basically a coil, the pipe loops around and comes back, it basically is supposed to cool the air. The pump specifications say about 2psi is released, how much heat would that generate... would it be significant?

Where does the pipe feel warm at? Before it re-enters your cooling device? After? Does the whole pipe slowly heat up? It could be that whatever you are using to cool your air simply cannot handle the amount of heat transfer needed to keep the air in the pipe cool.

The pipe feels warm where it loops back around, and the pipe starts cool but gradually heats up. What do you mean the air pump cannot handle the amount of heat transfer. Is it too weak or strong, it is basically a fish tank aquarium pump like this :(http://www.thatpetplace.com/silent-a...-gal-2-outlets )

Not the pump. I'm talking about whatever you are cooling the air in the pipe with.
