What is the primary function of a turbine's heat exchanger?

To cool the engine oil

To manage engine temperatures by exchanging heat between fluids

The primary function of a turbine's heat exchanger is to manage engine temperatures by exchanging heat between fluids. In turbine engines, maintaining optimal temperature is crucial for efficient performance and longevity of components. The heat exchanger facilitates this by transferring heat from the hotter fluid, typically engine oil or fuel, to a cooler fluid, helping to prevent overheating. This process not only enhances the efficiency of the engine but also contributes to maintaining the structural integrity of sensitive components. By regulating temperatures effectively, the heat exchanger plays a vital role in the overall thermal management system of turbine engines. This function is essential for ensuring the safe and reliable operation of the engine during various phases of flight and conditions.
