  • a/c air to the trunk?

    anyone ever tried to get the a/c air from the front to the trunk of a compact car or any car in fact?
    perhaps by means of some kind of tubing..... I hate hot weathers, I get really scared of turning on the PC.

    Yes I have thought of that in fact, I even tried it. What you need is some large like 1/2" tubing with a fan in about the first foot of it to push the air through it. There def is not enough pressure to just have a tube. If anyone else has ideas, im interested as well

      I think I will jsut connect straight into my CPU fan, it's one of those used for overclocking.. YStech fan. It's loud and pushes a lot of air...

      I jsut wanna know if anyone actually done this. I have a 97 civic and there is just not much space to run a decent diameter tube all the way to the trunk without looking too ugly...

      I will need to make some sort of connectors too I suppose....
      ACK! this is like a neverending project.. always something to mod with, no matter what you have done. LOL

        I've thought about running some sort of tubing to the trunk as well, but it would just be too ugly. So if it ever gets really hot, I just fold down one of my rear seatsand I get all sorts of air flow to the back.

          Well, you could run the tube under the car. Just tap off the AC under the dash, and straight down through the floor. Then come up through the floor of the trunk...But a better idea may be to just duct in some already cool air from under the seat or something....Have one fan push cold air into the trunk, the other fan remove the hot so it circulates properly.

            Think for a moment, about the air temp running through there in the winter. Or for the first few minutes after you turn on your car on a hot day...just make sure you figure in some way to cut the air supply.

              I actually did this using plastic tubing from Home Depot. It is not easy. It's a big job especially if you want it inconspicuous. It's rather difficult to achieve satisfactory result tho; like ppl said above you need a powerful AC and a very efficient airpath to the trunk. In my cheap design the AC air lost most of its cool by the time it reached the trunk. So I hooked the tubing to the computer case and added extra fan to blow the AC air directly into it. When I use this on the hottest day, the ambient temp in the case drops from 130F to about 100F so I guess it could be worthwhile for some people in hot climates.

                Old vacuum cleaner hose...

                  Vacuum hose is good, just don't get the plastic stuff. In a hot car, it will collapse. Use the old fabric stuff with the metal spring inside. By far, it's the best quality vacuum hose. Might be hard to find though, as vacuum stores pay a premium for good used hose when rebuilding vacuums. The new stuff is just so expensive.

                    You might want to avoid running the hose under the car, unless it is well insulated. Running cold air through a hose on the outside of a car to the boot (trunk) will make the air rather warm, very quickly. Maybe some sort of pickup under the back seat, fed by fans to the boot (trunk) is the best option.

                      Wouldn't this be a risky thing to do? Hooking up a direct air source from your A/C into your carputer? I'd think that the possible condensation would be a much greater risk than heat. Perhaps piping the A/C into the trunk itself would be better to allow a gradual temperature drop?

                        Depending on availability, and the space you have... you could always try to find an old rear A/C unit in a junkyard... many conversion vans have these... but unfourtunately I can assume many get picked up quickly or have many leaks... but its worth a try. Of course if you have too much money to know what's good for yah, you could probably get one from a dealer. Just a suggestion since running a tube seems to be hard. The only problem I see with the fans under the backseat to the trunk is the back of the car usually doesn't get cool enough quick enough, or at all if your A/C really sucks...lol

                        I'm sure someone out there has a good idea on how to do it... I'm actually really interested in the idea now even though I drive an SUV and dont have a trunk. It could be useful no matter where the computer is just to make sure you don't have any skipping problems... a cool computer is a happy computer!

                          I would try using a water cooling system and extend the tubes, this way you can hide the tubing and get a decent setup. Just have the radiator of the water cooler in front of one of your AC vents, or you could even put it into one of your AC vents if you wanted to.Also, you may want to add antifreeze to the water. You would also need to make sure that your connections are tight, your tubes won't get squished and your pump has enough power to move the water.

                            Since I live in florida and with august coming, I need to cool my system quick. Other wise it will cook in the trunk. Since some people are interested in cooling their trunks, this is what i plan to do before my carputer catches fire. (yes i already had one do that).

                              ok i think this is a very bad idea, evaporative cooling works by doing just that, it evaporates water into the air, which makes the air very moist, this can lead to your computer getting moist and we all know what happens then. on the other hand air conditioning take the moisture out of the air, so its perfectly fine to use to cool a computer, i dont know where these ides come from that air conditioning will cause condensation on your computer unless you cool the computer to very cold then turn the air con off there shouldnt be any condensation.
