Time to replace defective and potentially dangerous absorption fridge

Uh-Oh, I think I've been had haven't I??? LOL :-)

I'd like to add that slowing down coolant flow thru a radiator to engineer a top and bottom rad tank temp difference actually decreases heat transfer. The driving force for heat transfer is the temperature difference between the hot coolant and the cooler ambient air. To maximize heat transfer we want this delta-T to be large across the entire face of the radiator. By slowing down the coolant we're decreasing the delta-T across the face of the rad. (Look up log mean temperature difference). If an engine is happy with a 5 deg top/bottom tank delta rather than the more usual 15 deg, then heat transfer would increase. This seems intuitively correct because the difference in temperature between the coolant in the tubes and the ambient air across the full area of the radiator is higher if the top/bottom tank temp diff is less.

Shoot! I did it again didn't I??? Okay, I'll stop now!
