I'm looking for even just a little cool air for a hot summer trip in my '69 Beetle this August. I've been looking at the Koolaire thing which fits atop a cooler: http://www.kooleraire.com/index.htm but of all the reviews I've seen online, it seems like a 50/50 chance it's worth the $40. I took a look at the size of the cooler it fits and they aren't all that big. Does anyone have any experience with this product? The thing that bothers me is that I can't find cfm's listed for the fan.
This gave me an idea though, and I'm hoping this will kick off some new thinking and maybe some help. I'd seen this Heater/Defroster Assist Kit, that boosts the heater airflow with a couple of fans. Take a look: http://www.mamotorworks.com/acvw-1-54-6320.html
Well, these two ideas sorta merged in my head. I'm thinking I might be able to rig one or two of these fans to a foam cooler full of ice packs, frozen 2-liters or frozen 20oz bottles of water. I found this fan online, which looks like the same fan on the last link: http://www.shipstore.com/SS/HTML/ATT/ATT17334.html?zip=50265&Do+it=+submit
I've found these same fans on a couple different websites. They're 145 cfm open flow or 100 cfm inline. I’m not sure how exactly I’d go about this, but since I have no stereo in my Beetle, I’m thinking I could stick the cooler in the trunk, hook up the fans in there with it and run a little 3” hose into the cab through that opening. I can cut out a wood ‘grill’ for the air hose…
So, chime in with ideas, thoughts, discouragements…I’m not going to waste any money until I’m sure it’s worth it. I’m thinking of just getting one of those fans anyway since it's got a pretty good cfm rating and runs 12v. The big question on that is how to pull power for it... right off the battery? Do I need a fuse or something? I’m not all that good with wiring. Any ideas on what fuse to use or where to pull the power? Thanks in advance everyone :-)
