rztmartini Posted November 5, 2007 Share Posted November 5, 2007 I hear of people painting their intercoolers black to hide them, well why shouldn't I get it anodized? I have a hook-up with an anodizer, so other than the cost differences, why would it not be a god idea?? the reason i ask is cause im worried about the affects of heat transfer through the paint would be...not sure if these worries are valid or not... any input appreciated! -Jimmy Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted November 5, 2007 Share Posted November 5, 2007 anodizing usually looks funny on cast material, from what ive seen. There is suposedly special 'radiator' paint you can use on the cooler if you wanted to. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted November 5, 2007 Share Posted November 5, 2007 Eastwood sells the black radiator paint that's not supposed to impede heat transfer too much. Depending on how my grill turns out I might do that to mine. Mario Quote Link to comment Share on other sites More sharing options...
rztmartini Posted November 5, 2007 Author Share Posted November 5, 2007 are the cores of the ic's cast? i know the endtanks are, but they can be painted...its the core that worries me. Quote Link to comment Share on other sites More sharing options...
240hoke Posted November 5, 2007 Share Posted November 5, 2007 Just the cores are cast usually and it depends on how your center section is made, some are extruded and some are brazed bar and plate. I ended up powder coating my end tanks and then spraying a light coat of high heat spray paint on the center. Quote Link to comment Share on other sites More sharing options...
TheNeedForZ Posted November 6, 2007 Share Posted November 6, 2007 Anodized coating have thermal insulation property, not something you want on a heat exchanger. Fresh aluminum surface will have a very thin layer of oxide after exposed to oxygen, but anodized layer is much thicker. Quote Link to comment Share on other sites More sharing options...
badjuju Posted November 6, 2007 Share Posted November 6, 2007 My thoughts exactly. You probably won't notice a cooling difference, but it's like the idea of having a light inside your computer case. It'll generate some amount of heat, which is enough to offset the 'cool' look in my eyes. I say go for it though, the fact that we don't get IC's to begin with makes the heat argument a little silly. Your car. Find a sexy color and go to town. Quote Link to comment Share on other sites More sharing options...
Tony D Posted November 6, 2007 Share Posted November 6, 2007 Actually, testing on cases milspec anodized black recorded slightly better emissivity than bare aluminum. Milspec black or dark grey will help with corrosion prevention as well. many anodizers will not do cast because of customer complaints about 'splotchy' appearance...but the emissivity increase and corrosion prevention is worth it.

TheNeedForZ Posted November 7, 2007 Share Posted November 7, 2007 Interesting info on the emissivity test. Was the test done on emissivity alone or did the entire heat flow increase overall? With a radiator, I believe a bigger portion of heat is conducted away thru contact with air. If you put your hand near the radiator you will feel the heat but if you touch the radiator it'll be very hot. If the anodize coating promote heat radiation without hurting any contact transfer I'd say go for it. Quote Link to comment Share on other sites More sharing options...
