A320 Hydraulic Cooling
Hi there Ladies and Gents,
Had a look through the manuals and can't find where or how the Hydraulic Fluid on an A320 series aircraft is cooled.
From pervious experience, I know 737s have heat exchangers in the fuel tanks. What about the A320s?
Ta!

It doesn't require any additional cooling on the 320, there are merely overheat warnings for the pumps and reservoirs but the design is such that it doesn't need fuel cooling or other external cooling.

Look in the FCOM 1.70.40 (or 45) for "IDG Cooling System" .

IDG Cooling
ASFKAP:
You did remember correctly.
As I also remembered this I did some homework for you all, sorry this has deviated from the hyd cooling question.
The Integrated Drive Generator (IDG) oil-cooling system (Ref. 24-21-00) uses part of the fuel supply to each engine. During oil cooling the temperature of the fuel increases. The fuel recirculation for the cooling system (recirculation system) moves the warm fuel from the IDG cooling system to the wing tank.
Each engine has a recirculation pipe which moves the warm fuel to the wing tank. The interface between each IDG oil-cooling system and each recirculation pipe is a Fuel Return Valve (FRV).
The operation of the FRV is controlled by the Full Authority Digital Engine Control (FADEC) system.
