general question about condensers

hardbody on Tue April 26, 2011 9:08 PM User is offline

Just curious, why would a manufacturer paint/coat a condenser black? wouldn't the paint/coating effect the cooling properties of the metal in terms of it acting as a heat sink?

Looks - Yes you lose maybe 7 percent depending on how thick of a paint job they put on the condenser.


When considering your next auto A/C purchase, please consider the site that supports you:

because the buyer wants it that way for styling....

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Thanks, was just curious about that.

A black body radiates heat better, e.g., Harley's cylinder head cooling fins are painted black.
Painted condensers provide better countermeasure for corrosion.

My two GM vehicles have bare aluminum condensers. Anodizing is the preferred method for aluminum protection and even aids dissipation, my Supra has that.

So who is painting condensers? There are special radiator paints available that have an extremely thin coating. Use of conventional paints is never recommended.
