Without spending a ton of money, I wonder if anyone has come up with a suitable idea for providing cool air for an animal (maybe a kid, too...) that is left in the vehicle for short periods of time (say up to a 1/2 hour) so that the SPCA won't impound your vehicle and dog!
Today, I'm using a 12v oscillating fan that moves the interior air, with the rear windows down 4". It doesn't cool, but does provide an evaporation effect due to moving air. I have a "start pack" battery for this to plug into, as we know, the 12v port turns off with the key--I'm working on that issue, too!
I have an idea I want to pass by those "techies" in the group: There are these drink/food coolers that plug into 12v that promise to reduce the temp. by about 40 degrees F from ambient. So on a 100 F day outside, the inside could get up to 120-130?, so 40 degrees differential doesn't seem adequate.
I'm going to get a "cheap" cooler, take it apart to see how the mechanism and electronics are packaged, and see if I can make a "blow gun with chilled air" sort of gadget. The cooling modules are quite inexpensive, some offer up to 67 degrees C differential, and perhaps a couple of these mounted to some finned heat sinks would allow a "forced-air" cooling breeze.
Any ideas, thoughts, concerns why it wouldn't work, etc. I'd like to hear from those of you out there that are real techies. My industrial engineering expertise (before retiring 5+ years ago) was in thermal hydraulics as in moving a fluid of 400 F at 600-1000 psi. No cooling experience!
Rather than post on this forum, please PM me.
Thnx, ja
