Black is a good emitter of infra-red radiation than white or any other light colours, so it will allow the temperature of the cooling fins to fall quickly.

Why are the cooling fins at the back of the refrigerator usually painted black and have a rough surface?
Usually it is rough so anything in there or by the inside can be broken up, I think.
What colour are the cooling fins of a refrigerator?
black
What is the purpose of the fins on the condenser?
cooling
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
Why does the number of cooling fins affect the rate of energy transfer from the radiator?
Because the more coolant passed through the fins, the more energy can be emitted.

What colour are the cooling fins of a refrigerator?
black
Why is cooling fins painted dull black?
A black body radiates more heat than any other. Therefore if you want to lose heat, paint it black (unless of course it is in the sun where the black paint might have some heat absorption properties for unrelated reasons.)

What material are cooling fins?
Aluminum or copper.
What does a cooling fin do on a motorbike?
cooling fins are used to cool down the engine by having the cool air pass through the fins which gets transferred down to the engine, so on a motorbike like all other engine's the cooling fins cool down the engine.
What is the use of fins in tri gate transistors?
cooling
How does an air cooled system work?
An air cooled system uses cooling fins, in which air is either blown past these fins by a flywheel or a cooling fan, this air that is blown into these fins carries residual heat away from the cylinder jug.
What effect will bent cooling fins on the condenser have on the refrigerant system?
Efficiency drops dramatically depending on how badly bent the fins are.
Why is the cooling fins of the refrigerator placed near the top of its cabinet?
answ2. The cooling fins are actually the device by which the frig gets rid of its unwanted process heat. Thus they are warmer than the surrounding air.Where they are placed is entirely at the discretion of the manufacturer.Indeed, many chest type deep freezers have no cooling fins at all! They use the external carcase of the device to dissipate the unwanted heat, and rely on superior insulation to keep this heat away from the cold interior. For chest type deep freezers are opened much less often than a kitchen frig, and therefore have much less work to do.A1. Since the cooling fins are at the top of the refridgerator, it will cool down the air at the top. Then, this cool air will sink and the warmer air will rise to be cooled again efficiently by the cooler.-ASHWIN
Does the cooling fins on a car engine?
On cars that have them they are air cooled since there is no radiator.
