Where is the hydraulic fluid heat exchanger for hydraulic System B located?

• A. Main fuel tank No. 1
• B. Main fuel tank No. 2
• C. In the hydraulic reservoir
• D. In the auxiliary fuel tank

Answer: (B)

The hydraulic fluid heat exchanger for hydraulic System B is located in Main fuel tank No. 2 due to its integral design that accommodates synchronization with the fuel system and enhances operational efficiency. Placing the heat exchanger here allows for effective heat transfer during hydraulic fluid circulation, as the fuel tank serves both as a reservoir for fuel and as a medium for heat exchange. This design is particularly beneficial because it helps maintain optimal fluid temperatures, ensuring the hydraulic system operates within the desired temperature range, thereby prolonging component life and maintaining system performance.

While the hydraulic reservoir and other tanks might be practical locations for heat exchangers in different system designs, for System B specifically, the choice of Main fuel tank No. 2 aligns with the overall engineering and thermal management considerations needed in that setup.
