Re: Heat exchanger design - Flat vs Rround Tube
On both vehicles the cabin air filter is in the cowl panel (between the hood and windshield). It appears to be for fresh air only, but its very difficult to see in. when you pop the panel you just stick your hand in the slot and pull it out, so no idea how its plumbed. I will be glad to have fresh o...

Re: Heat exchanger design - Flat vs Rround Tube
Again, thank you tbird. the lead 'piccolo' has lead me to condenser design, and a better understanding of the construction of these heat exchangers. And this topic has been discussed numerous times. I can observe that on a parallel flow there is not one, but multiple orifices in the lines, and that ...

Re: Heat exchanger design - Flat vs Rround Tube
Not sure why you keep on about the cabin air filter? Looks fine to me :) Seriously, It may be moot with regard to the AC . This vehicle has not discreet recirc control. There is MAX AC, and AC. Max is recirc, while AC is fresh air. You can believe that that and the passenger side gas fill tube are m...

Re: Heat exchanger design - Flat vs Rround Tube
Thank for the good inf tbird, I'm not doubting parallel flow condensers ability for thermal exchange; Rather the modification of the OEM design. Its worth mentioning that phase exchange systems are balanced with numerous considerations. There are a number of departures on this vehicle. For one, VIN ...

Re: Heat exchanger design - Flat vs Rround Tube
Interesting, was unaware that pressures were taken at load. I will get that and the vent temps. Actually the OEM design is R134a with a dual core, tube condenser; Hence my concern for the single core flat tube. It does have 3 or 4 more runs, but I doubt that would make up for orifice size. Those hol...

Heat exchanger design - Flat vs Rround Tube
What I wanted to talk about was the design differences between flat tube and round tube design in heat exchangers. Traditional radiator, condensers etc used round tubes. Now however most certainly due to reduced production cost, most all are flat tube. I have a real world problem that has presented ...
