Cooler or Refrigerator? Want to eat healthy on the road.

Colman 12v cooler is about $100 and the lunchbox cooker that will heat soup and other food is about $25. Both well worth the $$ and seem to last a while

 

Im pretty sure the outside fan is 92mm but i would still double check

edit-- someone posted this one a while back as a replacement but it may have said you have to do some modifications to the cover Amazon.com: Swellder Delta FFB0912VHE 92mmx38mm High Power Cooling Fan Ball bearing fan DC 12V Brushless Fan -0.75A- 85 CFM: Computers & Accessories

 

You are going to love it. Makes an enormous difference to life on the road.

 

I am going to glue one of those to the wall of my fridge. It will make it work more efficiently I think.

 

Not so sure about that. Piezocoolers work by removing heat with electricity being passed through oddball materials. Its not very fast, but it is pretty darn efficient. The fans are on the outside of the cooler and have no impact on the air in the cooler. They just cool the 'hot' side of the heat transfer system.

If you put a circulating fan inside the cooler, then you will be putting a small heat source in the cooler. In a normal fridge, that heat source is nothing compared to how fast the gas coolant system can suck heat out. In a piezocooler, that tiny heat source could make a significant difference in the efficiency of the system.

Also, I'm fairly confident that piezocoolers don't remove heat fast enough that convection will help much. The natural inclination for heated air to rise to the top of the cooler doesn't use any energy, or generate any extra heat.

It's worth trying, but I don't think you will get the results you want.

 

read my post again Bob. The one you quoted.

 

Hem. Looks like I goofed. I read cooler instead of fridge, since most of the discussion has been about coolers. My bad.

 

OK, I am getting ready to go OTR, I have been reading the electric cooler vs ice chest threads.... I am leaning towards a Yeti modified with the drain pulg option, attached to tubing leading out of the truck. In theory all I have to do is add ice. My logic is that I'll avoid the converter, melted wires, blown fuses, etc. What am I missing?

 

Maybe it is just me. However I never had much luck with those new non-moving cooling systems. I could put a 1/2 gallon of milk in one say one day 1 all was OK. Then on day 2 the package was 1/2 frozen. Honestly if I had it to do all over again I would have got a small refrigerator. The thing is something one of my cousins told me 10 years or so ago sticks in my claw. He said his dad started driving as a part of the Red Ball Express then drove from the end of the war until around 1992 as an OTR driver. He got by just fine with nothing in his truck to keep stuff cool. I often wonder how those guys did it all those years. Must have been pure hell!
