Monty is also correct about the need for studying steady state conditions.  You need to do that and the transient stuff to get the whole picture.  I posted a transient snapshot because it illustrated a few points I was interested in and the fact that a bunch of straight lines on a graph are much less visually interesting.

Years ago I built a Camel Lights car (rotary powered of course) with nice gull wing doors and a nose mounted radiator just a few inches above the track. Using 140 degree track temp air for cooling paid off with poor cooling in the 120 plus area. I installed a "Marginal" Harrison Evaporator core in a partially submerged duct in the right side of the car, about a foot above the track, and the temp dropped to 160 degrees max. I just plugged it into the heater core supply connection.

 

Trans Am cars with huge radiators use spray bars on the radiators and in the brake ducting. In aircraft the spray bar should be mandatory. The switch you throw right after nearest and "What the heck was that?
