2.10. FUEL OIL-COOLER

Some turbine engines use a fuel oil-cooler or heat exchanger to cool the lubricating oil. This unit is discussed under the lubrication system because its prime function is to help cool the oil. It consists of a cylindrical oil chamber surrounded by a jacket through which the fuel passes. Heat from the oil is transferred to the fuel via conduction*. Figure 2.11 shows a typical fuel oil-cooler.
