Redneck A/C Cletus style REVISTED

[unclefish]

So will you just attach the heater core to the lid with epoxy too? How heavy is that core?

Looking good so far.

No, I'm going to use zip ties. If this doesn't work like I hope it does I want to be able to reuse the heater core for the next build. I'm thinking the fan would work best inside the cooler blowing cold air out. I had that thought after I had the fan epoxied to the lid.

Well fellas made my own today here's prices and how well it works. I got all me supplies at Walmart other than the pvc 4" elbow. I used a foam cooler because I didn't have an old one laying arould that I was willing to cut holes in. A 6" dual speed fan and a smaller single speed for the exhaust I epoxied the large fan in place as my inflow and epoxied the small fan to the 4" pvc elbow just used foam from the craft section to make the center air diverter total cost of all my supplies was $36.56 and that's incuding paying obama!

TEST: I'm not only using my cooler a/c for the blind but for my truck too so that when I go to the store I don't have to leave the truck running while my dog is in there. So I started my truck and let the temp get down to what a normal car ride would be. I plugged in the fans to the outlet in my truck and turned of the truck. My truck is sitting in the sun and is black its also a f250 crew cab so its a pretty large area. It was 74* in there 45 min ago and is now 76 I think this thing is actually working quite well in the truck!8

Where's the pics or it didn't happen

[Coach W]

Ok following this one... Not sure how I missed the first one!

[hillcountrytx]

Hey cletus ill try and post up a pic of my cooler a/c tomorrow I don't have internet att my house and we don't have 3g in my area so ill have to try and steal WiFi from someone Haha. And like I said before I used the cooler to sustain a current temp not actually make it colder so I think it works for that quite well. Sorry I didn't take pics of the thermometers cuz I figured I wouldn't be able to post em anyways!

Iv also seen a few different ones that instead of using ice jugs as the cooling agent the used an old coil from a fridge and got a 12v fountain pump and used it to circulate the freon and also used the coin and added water in the winter and the heat produced from the pump running heats the water and is used as a heater as well but that may be a little too in depth for me!

[CletusBodeen]

Well, I got the heater core attached and put some water and ice in the cooler for a little test. Test didn't go so great. The ice water chills the crap out of the heater core but I'm not getting air flow throw it. The only way this will work is with another fan pushing air out of the vent. I think I wasted money trying this style. My original redneck a/c works a whole lot better than this one. I will keep tinkering with it and i'll get a fan like on my other one to use to push air out the vent. I'll have to get something different for my vent than what I had planned.

Where did you get the heater core?
How much?
What model car is it for?
With that fan, you need a larger diameter vent pipe. should be same as, or close to fan diameter. the small vent is restricting the air flow.
Does that fan have a varible speed switch?

need bigger vent!!!!!!!!!!!!

[txfireguy2003]

I agree with Sticks. The heater core idea, in theory, should be much more efficient than just blowing air over chunks of ice, but you have to have enough pressure from the blower to push the air through the core AND out of the vent. So, you either need a bigger vent pipe, OR a different style fan. That style fan is not designed to push air with a lot of back pressure, so something's gotta give.

No vent cut yet. I was running it with the lid open and felt very little air coming through the heater core.

Maybe its the type of heater core. Sticks said he used an 87 chevette core....and you used a ford escort. Maybe the chevette core is more porous than the escort's.

Could be but a Ford heater core is a lot cheaper. I have a change in mind to make to it and see what it does.
