  • Neat idea for heat control

    I know some people have ran ducting from their a/c to their case for cooling. For a while I wondered what people do in the winter when its blowing heat instead of cool air. So I had an idea to get a butterfly valve(like out of a carburetor) and control it with a servo motor programed to rotate the valve 90deg from wide open to closed and vice versa. Take it one step further and put a temperature sensor before the butterfly valve and modify the app controlling the servo to close the valve if the temp is >=X degrees and BAM! your computer will automatically get a/c but not heat. Yes I know it's on over the top solution for a small(non?) issue, but its one of those things to do if only for the sake of doing it and showing off. I'm probably not going to do it but I always like hearing new ideas so I figured I'd share mine.

      Condensation is bad.

        This is what I am doing (ducting a/c on the processor/board). I really have no choice since I am in AZ and the heat is a killer for something like a carputer. I would like to do something like you described, but have not seen a suitable buterfly valve yet.

          go to a junk yard and look..
          i would think a air box -the part with the blower moter would do well
          most car from japan use what i am talking about, you may be able to find on with a steper moter already on it. that can make life easier since your range and travel will be corect for the fresh air door.

            I could be mistaken but I believe a/c's dehumidify, hence the water puddles under the compressor after the car is parked.

              You are correct. In fact that is why your A/C compressor runs when you turn on your defrosters.

              edit> However, any moisture in the car that drops below the dew point will condense onto hot electornics.

                the a/c drain s not 100% effecent.
                when you turn off your car the condensor is still cold and condensation runs to the bottom of the a/c box. this is where you will get a musty smell from the a/c.
                when you first start your fan this humid air is push out and into the cabin (or your pc)
                witch may or may not be cooler if it is cooler then it will condence on the MB , drives or whatever. if you set it up with a delay would defintly help this or you may want to get a case fan control that uses a temp sensor to turn on a fan, but use the control to open the vent to allow air flow from the a/c. this may delay opening long enough for the a/c to dry out. also most case fans are 12 volt and so are most automotive steper moters. just remember to use a relay.
