Karen, you were way ahaead of my know what this thing was, but I did understand what you meant with out your hubbies clarifications.Quote:ok he agreed, it's a resistive heating setup, where the flow of electricity from one point to another is causing the heat. he said it's the flow of electricity that causes the heat, not the resistance to flow... I had it backwards.a radiator and similar heating/cooling systems would have a liquid flowing thru, and the fins are used as a heat exchanger. since it doesn't appear to be fluid filled,
this looks more like a resistive heating setup, where current is passed thru the metal and the resistance of the metal is causing it to heat up... i'll ask hubby (the automotive and electronics wiz) a bit later and see what he thinks.
do you have any larger/higher quality images?
