Re: Old radiator shot, thinking about Jeg's Universal Aluminum, any one done this?
I would like to add another question to this debate. Alum. radiators are left unfinished (no paint). Copper Radiators are painted. I think that the paint on a copper unit would diminish it's transfer capabitlities. While the alum. is left unfinished, it would transfer heat at a faster rate.
I would imagine that all of this is cost related. But with a Be Cool costing upwards of $500, Construction cost does look to be an issue. For that kind of money performance should be the only concern. If copper worked better, I would think copper is what they would use. Aluminum is used on all kinds of heat sinks, not copper. Heck, if I want to thaw meat out quickly I put it on an alum cookie sheet and place it where air can move around it. Meat will thaw up to 3-4 times the rate vs just setting it out on the counter. Of course we have no copper cookie sheet so I can't test the alternative. I do know this. Copper will scale up faster than alum. inside, thus decreasing it's transfer rate. Alum. will not scale like copper, and would transfer better over the life of the unit. This is probably one of the biggest factor in the material used, aside from cost. I also question wether copper will TRANSFER heat to air, any faster than aluminum? I know coppper CONDUCTS better, but TRANSFER to air is another matter. Then the paint comes into play as well. The paint is an insulator. It's not meant to be that, but IS none the less. When mine goes, it will get replaced w/aluminum. Jay
