737NG extra hole ?

Just out of curiosity - I notice the NG 737's have sprouted an extra hole just above the APU exhaust ( about 6" dia ). Anyone know what it's for ? Anti-icing air outlet perhaps ?

Thanks in advance

According to my Black Book it is the Cooling Air Inlet. Cooling air enters here and circulates around the APU, through the oil cooler and leaves via the exhaust outlet.The engine air for the APU still enters at the air inlet door on the starboard side of the aircraft though. I know it seems strange to have an air intake at the back of the a/c but now you know!!
