2.2. Heat Exchange Structure

– Hot oil from the hydraulic system or gearbox is pumped into the heat exchanger core of the cooler.
– The aluminum heat exchanger core consists of numerous tubes and fins to increase the heat transfer surface area.
– A cooling fan creates a forced airflow through the fins.
– Heat from the oil is transferred through the tube walls to the fins.
– The air carries the heat away from the environment, reducing the oil temperature before it returns to the system.
